النظافة والتعقيم كما نعرف جميعنا انهم من الضروريات المهمة جدا سواء كانت نظافة شخصية او نظافة المنازل وتعقيمها لان هذه العملية تحافظ على صحة الانسان جيده دون حدوث اى امراض له وكما نعرف ايضا ان هناك مرض لعين قد انتشر في الفترة الاخيرة بطريقة كبيرة جدا فيروس كورونا المستجد فكان لابد من التعقيم المستمر لتجنب انتشار هذا المرض او العدوى ولكي نحافظ على اسرتنا واطفالنا من هذا الفيروس كان لابد من وجود نصائح للتعقيم الصحيح كما سنذكرها لكم الان وتكون الطرق المثالية للتعقيم من خلال مواد معقمة سريعة جدا وغير مكلفة وبدون جهد كبير تكاد تكون متواجدة في كل منزل او يمكنك الحصول عليها من خلال شركة تعقيم المنازل.

قبل ان نبدأ بخطواتنا الاولي لتعقيم المنزل لابد اولا ان ننظفه بالكامل لان معظم الاوساخ التى تتراكم على الاسطح هى المكون الاساسي للميكروبات والجراثيم فيجب عليكي ان تحضرى فوطة غير مبللة وتقومى بازالة جميع الاتربة التى توجد بالمنزل من الاعلى الى الاسفل دون استخدام الماء حتى لا تحدث اي ترسبات، والان انتهينا من الاتربة احضرى بعض الماء وسائل المنظف وامسحي الاثاث والقطع التى قمتى بازالة الاتربة عنها ثم قومى بغسل يديكى جيدا بالمياه والصابون  لمدة 30 ثانية تبعا لنصائح شركة تعقيم.

 

لقد انتهينا من التنظيف الان يمكننا ان نقوم بتعقيم المنزل بالكامل بكل سهولة من خلال احضار بعض المطهرات مثل الكلور من خلال خلط  4 ملاعق صغيرة منه في ربع لتر من الماء او مجموعة مناديل مبللة تحتوي على تركيز كحول 70% أو أكثر

او مطهرات الأيدي التي تحتوي على تركيز الكحول بنسبة 60% على الأقل او استخدام بيروكسيد الهيدروجين وهذه تكون المواد التى يمكننا استخدامها في التعقيم بالنسب المناسبة التى قدرتها منظمة الصحة العالمية و شركات تعقيم المنازل.

الان نبدأ بالاسطح عليك  ارتداء قفازات الايدى واحضار قطنة نظيفة وفرشاة تنظيف والكلور واغمسي القطنة هذه بالكلور ثم خذيها وعقمى جميع اجزاء المنزل بحرص ولكن يجب الا يلامس الكلور يديكى ابدا.

ثم ننتقل الى الحمامات التى تكون اكثر عرضة للجراثيم ونقوم باستخدام بيروكسيد الهيدروجين والماء وخلطهم جيدا وتطهير الحمام بهم جيدا ثم استخدمى قطنة جافة لمسح الحمام من وجود اى ترسبات كما تفعل شركة تعقيم منازل.

والان احضرى بعض المطهرات الاخرى والماء كما ذكرنا في السابق وقومى بمسح الارضيات جيدا وتعقيمها من اثار اى جراثيم والان اصبح المنزل معقم بالكامل وقد حصلتى على الوقاية الكاملة لعائلتك لان الوقاية في اغلب الحالات تكون افضل من العلاج

ملحوظة:- ان كنتى تريدين استخدام الكحول الإيثيلي لابد ان يكون بنسبة 70% حتى يقتل الفيروسات والميكروبات وبعد الانتهاء يجب التأكد من إحكام غلق محلول الكحول لأنه يتطاير سريعًا كما يجب التخلص من القفازات بعد الانتهاء من التنظيف بعد الانتهاء من عملية التعقيم والتنظيف يجب غسل اليدين جيدًا وعدم ملامسة اليد للوجه أثناء التنظيف والتعقيم حتى مع ارتداء القفازات، ينبغي عدم ملامسة اليد للوجه أثناء تنظيف الأسطح

Status And Future Of 5G New Radio Technology

Edit setfor Status And Future Of 5G New Radio Technology

What is 5G New Radio (NR)?

5G New Radio (NR) is a new radio access technology (RAT) developed by 3GPP for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G New Radio (NR) networks.

The 3GPP specification 38 series provides the technical details behind NR, the RAT beyond LTE.

The study of NR within 3GPP started in 2015, and the first specification was made available by the end of 2017. While the 3GPP standardization process was ongoing, the industry had already begun efforts to implement infrastructure compliant with the draft standard, with the expectation that the first large-scale commercial launch of 5G NR would occur in 2019.

The 5G core network (5GC) is the brain of the 5G mobile communication network, which is responsible for managing and controlling the entire network.

The 5G core network is a collective name of many 5G NE equipment and is not specifically referred to as a network element device.

AMF (Access and Mobility Management Function Access and Mobility Management) supports a UE with different mobility management requirements. AMF can be classified as 4G MME.

Store and manage the permanent user ID (SUPI) of the 5G system;

AN (Access Network) is the access network, which can be a 3GPP access network (such as LTE, 5G-NR), or a Non-3GPP access network (such as common WiFi access).

While 5G has been a hot topic for years, there is still a great deal of work to be done behind the scenes in refining and effectively iterating on 5G standards.

5G NR (New Radio) Release 16 brings critical reliability and latency improvement technologies in several key areas, most notably an enhanced 5G URLLC base to deliver better link reliability (up to 99.9999%).

These networks have gained significant traction in industrial IoT use cases, enabling enterprises to deploy 5G industrial IoT networks with dedicated resources immediately, rather than waiting for broader 5G network deployments. Other benefits include specific optimizations for local applications and customized security and privacy settings when needed.

How To Make A 433MHz Antenna Design

Edit setfor How To Make A 433MHz Antenna Design

For a wireless system, a problem needs to be considered in the 433MHz antenna design. The 433MHz antenna design is a very precise task. A good 433MHz antenna needs to consider issues such as frequency band, impedance, and gain.

The simplest 433MHz antenna design is a whip antenna design, which is a 1/4-wavelength line placed on a ground plane. The most common examples are used in wireless broadcast radios, cable equalization amplifiers, amateur radio stations, and cellular phones.

All antennas, like any other element, have at least two connection points. For whip antennas, there must be a connection point and ground connection, although there is only one circuit trace and one battery in the ground layer area.

The whip antenna and the ground layer combine to form a complete circuit. A magnetic field is established between the whip antenna and the ground wire layer. When current passes through the field, the entire circuit is formed. The ideal ground plane should extend at least 1/4 wavelength around the whip antenna base, or more.

Apple's first use of UWB is to provide positioning data. Location Supports Many applications in the fields of reality (AR), virtual reality (VR), games, equipment recovery, file sharing, and advertising beacons.

Development of UWB technology

With the growth of wireless communication demand in 1990, the advantages of ultra-wideband (UWB) become more obvious.

In 2002, Wi-Fi is still a relatively new technology. The 802.11b router was launched in 1999, the theoretical maximum speed of the 2.4 GHz band is 11 Mbit / s.

802.11A standard is also defined in 1999 and promised that the theoretical speed in the 5 GHz band is 54 Mbit / s, but due to its higher chip group cost, there is no attention in the consumer.

The 7.5 GHz bandwidth allocated between 3.1 GHz and 10.6 GHz is extremely valuable for wireless communication engineers.

How To Solve The Warpage Defect In Injection Molding Of Thin-Walled Products?

Edit setfor How To Solve The Warpage Defect In Injection Molding Of Thin-Walled Products?

What is a warpage defect in injection molding?

Warpage defect in injection molding is one of the common defects in injection molding of thin-walled plastic parts.

When the warpage deformation exceeds the allowable error, it becomes a molding defect, which affects the product assembly. Accurate analysis of the warpage defect in injection molding of a large number of thin-walled products is a prerequisite for effective control of warpage defects.

Most of the warpage defect in injection molding analysis adopts qualitative analysis, and measures are taken from the aspects of product design, mold design, and injection molding process conditions to minimize the degree of warpage deformation.

The injection mold acceptance standard is recognized from the product quality, mold structure, injection molding process requirements, etc., accordingly, the injection mold quality is evaluated.

The cooling water juice should be used in the plastic block insertion mouth, and the customer needs to request.

The hardness of the mold components should not be less than 50 HRC, or the surface hardening treatment hardness should be higher than 600 hV.

The reset spring should be used as a standard piece, and the spring should not be ground and cut.

Below are the 18 basic injection molding technologies that injection molding technicians must know.

The melt usually flows from the nozzle into the nozzle, but in some injection molds, the nozzle is part of the mold because it extends to the bottom of the mold. There are also two main types of nozzles: open nozzles and closed nozzles. In injection molding, open nozzles should be used more because they are cheaper and less likely to stay.

Make sure that the nozzle is correctly connected to the nozzle bushing, and the top hole is slightly smaller than the nozzle sprue bushing.

Edit setfor How To Solve The Warpage Defect In Injection Molding Of Thin-Walled Products?

What is a warpage defect in injection molding?

Warpage defect in injection molding is one of the common defects in injection molding of thin-walled plastic parts.

When the warpage deformation exceeds the allowable error, it becomes a molding defect, which affects the product assembly. Accurate analysis of the warpage defect in injection molding of a large number of thin-walled products is a prerequisite for effective control of warpage defects.

Most of the warpage defect in injection molding analysis adopts qualitative analysis, and measures are taken from the aspects of product design, mold design, and injection molding process conditions to minimize the degree of warpage deformation.

The injection mold acceptance standard is recognized from the product quality, mold structure, injection molding process requirements, etc., accordingly, the injection mold quality is evaluated.

The cooling water juice should be used in the plastic block insertion mouth, and the customer needs to request.

The hardness of the mold components should not be less than 50 HRC, or the surface hardening treatment hardness should be higher than 600 hV.

The reset spring should be used as a standard piece, and the spring should not be ground and cut.

The melt usually flows from the nozzle into the nozzle, but in some injection molds, the nozzle is part of the mold because it extends to the bottom of the mold. There are also two main types of nozzles: open nozzles and closed nozzles. In injection molding, open nozzles should be used more because they are cheaper and less likely to stay.

Make sure that the nozzle is correctly connected to the nozzle bushing, and the top hole is slightly smaller than the nozzle sprue bushing.

Status And Future Of 5G New Radio Technology

Edit setfor Status And Future Of 5G New Radio Technology

What is 5G New Radio (NR)?

5G New Radio (NR) is a new radio access technology (RAT) developed by 3GPP for the 5G (fifth generation) mobile network. It was designed to be the global standard for the air interface of 5G New Radio (NR) networks.

The 3GPP specification 38 series provides the technical details behind NR, the RAT beyond LTE.

The study of NR within 3GPP started in 2015, and the first specification was made available by the end of 2017. While the 3GPP standardization process was ongoing, the industry had already begun efforts to implement infrastructure compliant with the draft standard, with the expectation that the first large-scale commercial launch of 5G NR would occur in 2019.

Apple's first use of UWB is to provide positioning data. Location Supports Many applications in the fields of reality (AR), virtual reality (VR), games, equipment recovery, file sharing, and advertising beacons.

Development of UWB technology

With the growth of wireless communication demand in 1990, the advantages of ultra-wideband (UWB) become more obvious.

In 2002, Wi-Fi is still a relatively new technology. The 802.11b router was launched in 1999, the theoretical maximum speed of the 2.4 GHz band is 11 Mbit / s.

802.11A standard is also defined in 1999 and promised that the theoretical speed in the 5 GHz band is 54 Mbit / s, but due to its higher chip group cost, there is no attention in the consumer.

The 7.5 GHz bandwidth allocated between 3.1 GHz and 10.6 GHz is extremely valuable for wireless communication engineers.

For a wireless system, a problem needs to be considered in the 433MHz antenna design. The 433MHz antenna design is a very precise task. A good 433MHz antenna needs to consider issues such as frequency band, impedance, and gain.

The simplest 433MHz antenna design is a whip antenna design, which is a 1/4-wavelength line placed on a ground plane. The most common examples are used in wireless broadcast radios, cable equalization amplifiers, amateur radio stations, and cellular phones.

All antennas, like any other element, have at least two connection points. For whip antennas, there must be a connection point and ground connection, although there is only one circuit trace and one battery in the ground layer area.

The whip antenna and the ground layer combine to form a complete circuit. A magnetic field is established between the whip antenna and the ground wire layer. When current passes through the field, the entire circuit is formed. The ideal ground plane should extend at least 1/4 wavelength around the whip antenna base, or more.

While 5G has been a hot topic for years, there is still a great deal of work to be done behind the scenes in refining and effectively iterating on 5G standards.

5G NR (New Radio) Release 16 brings critical reliability and latency improvement technologies in several key areas, most notably an enhanced 5G URLLC base to deliver better link reliability (up to 99.9999%).

These networks have gained significant traction in industrial IoT use cases, enabling enterprises to deploy 5G industrial IoT networks with dedicated resources immediately, rather than waiting for broader 5G network deployments. Other benefits include specific optimizations for local applications and customized security and privacy settings when needed.

Apple's first use of UWB is to provide positioning data. Location Supports Many applications in the fields of reality (AR), virtual reality (VR), games, equipment recovery, file sharing, and advertising beacons.

Development of UWB technology

With the growth of wireless communication demand in 1990, the advantages of ultra-wideband (UWB) become more obvious.

In 2002, Wi-Fi is still a relatively new technology. The 802.11b router was launched in 1999, the theoretical maximum speed of the 2.4 GHz band is 11 Mbit / s.

802.11A standard is also defined in 1999 and promised that the theoretical speed in the 5 GHz band is 54 Mbit / s, but due to its higher chip group cost, there is no attention in the consumer.

The 7.5 GHz bandwidth allocated between 3.1 GHz and 10.6 GHz is extremely valuable for wireless communication engineers.

9 Common Injection Molding Defects

Edit setfor 9 Common Injection Molding Defects

This article mainly describes 9 common injection molding defects and the causes and solutions for these injection molding defects.

During the injection molding process, the gate stacks to the sprue bushing, making it difficult to pull out. Opening the injection mold will crack and damage the product. In addition, the tip of the copper rod must be knocked out from the nozzle to loosen it, which greatly affects production efficiency.

Since it is difficult to machine the tapered hole of the sprue bush, you need to use standard parts as much as possible, and if you need to machine it yourself, you need to make it yourself or purchase a special reamer. The taper hole needs to be polished to Ra0.4 or higher. In addition, you need to have a gate pull rod or gate eject.

To solve the above problems, high-strength positioning keys have been added to each of the four sides of the mold parting surface. The easiest and most effective way is to use a cylindrical key. The verticality of the guide pin holes and the parting surface is very important.

Below are the 18 basic injection molding technologies that injection molding technicians must know.

The melt usually flows from the nozzle into the nozzle, but in some injection molds, the nozzle is part of the mold because it extends to the bottom of the mold. There are also two main types of nozzles: open nozzles and closed nozzles. In injection molding, open nozzles should be used more because they are cheaper and less likely to stay.

Make sure that the nozzle is correctly connected to the nozzle bushing, and the top hole is slightly smaller than the nozzle sprue bushing.
