For buyers, the main point when buying silicone products is to find a reliable supplier, because high-quality manufacturers can provide you with good sources of goods, and these manufacturers have one thing in common,  silicone compression molding   that is, their supporting industries are very complete. Hardware workshop: It needs related hardware operation lines. The hardware factory is a very traditional processing factory. The scale of the factory is large and small, and some silicone products also use hardware. Printing workshop: Quite a lot of products need to be printed with various patterns. Now many custom silicone products customers will require related patterns and LOGOs to be printed on the surface and inner side of the product. Oil spray workshop: Because silica gel has a more hand feel, it is generally used to spray hand feel oil, and such silica products are mostly silica gel protective covers, silica daily necessities and other silica products that come into co...

What is the role of network firewall

In general, the goal of information security is to ensure confidentiality and integrity, and the industrial network can only be put into operation after multiple encryptions. So what is the role of the network  industrial firewall ? 1. Strong pertinence A firewall is software or hardware that restricts access between systems or networks according to specific security policies. Network segment division and virtual local area network can make the division of security domains more detailed, so as to better deploy firewalls. 2. Safety The firewall acts as a gatekeeper between different security domains. The function of the firewall is to isolate different security domains, monitor the communication data of the network, and provide a trusted path for legitimate users and legitimate devices only when the relevant rules are effectively configured. channel of letter. 3. All-round protection Firewalls include two categories: host firewalls and network firewalls. The main form of host firew...

How to identify whether the mattress has good elasticity

In order to identify the elasticity of the mattress, you can use your knees to test the surface of the bed,  online mattress store or sit down in the corner of the bed to see if the compressed mattress can quickly return to its original shape. A good mattress with good elasticity can return to its original shape immediately after being compressed. When buying a mattress, the touch of your hand is not enough to identify a good or bad mattress. The most reliable way to identify it is to lie down and turn left and right. A good mattress has absolutely no bumps, sagging edges, or shifting linings. like: How to choose the right mattress for home What are the advantages and disadvantages of latex mattresses?

Characteristics of railway logistics transportation

Railway logistics transportation is generally calculated according to the truck container section by section.  railway transport services  The disadvantage of railway logistics transportation is that it takes a long time to wait, and then does not support door-to-door delivery, but compared with land logistics transportation, Its one-time delivery volume is relatively large, and its safety is relatively high. The logistics company stated that the difference between railway logistics transportation and land logistics transportation is not very big, but we still need to consider the safety of transportation and the time of arrival when choosing, and the transportation company needs to strengthen the logistics transportation management to achieve these. like: How to choose a logistics and transportation company?  Advantages of rail transport logistics   The scope of application of railway transportation 

The difference between wifi module and wireless module

The wireless module includes a communication module and a positioning module including a  router module , a Bluetooth module, and a GPS module; the WiFi module is just one of the non-cellular communication modules in the wireless module. The WiFi solution is based on the WiFi module that conforms to the IEEE802.11 protocol stack network standard and has a built-in TCP/IP protocol stack, so as to realize any transparent conversion between the three interfaces of the user serial port, Ethernet and wireless network (WIFI), making the The traditional serial device is better to join the wireless network. The type of WiFi module can be roughly known from the WiFi solution. At present, SKYLAB's WiFi modules in the market are roughly divided into three series: USB WiFi module, AP/Router WiFi module and UART WiFi module. like: How to Choose the Right Wi-Fi Router for Your Own Use How to choose a WiFi module manufacturer Factors to Consider When Choosing a Modular Router

Features and functions of LED rainproof power supply

LED rain-proof power supply is a kind of  rainproof led power supply 400w  It is a voltage converter that converts the power supply into a specific voltage and current to drive LED lighting. Usually, the input of LED driving power supply includes high-voltage power frequency AC (ie mains). , low-voltage DC, high-voltage DC, low-voltage high-frequency AC (such as the output of electronic transformers), etc. The output of the LED drive power supply is mostly a constant current source that can change the voltage with the change of the LED forward voltage drop value. It is different from the general LED driving power supply in the rainproof function. According to different needs, it can be designed to be IP65, IP66, IP67, IP68 and other waterproof and dustproof grades. Among them, the IP68 grade can be completely immersed in water. like: What are the characteristics of led rainproof power supply? What is the main function of the rainproof power supply?

The role of transcutaneous electrical nerve stimulation

Transcutaneous electrical nerve stimulation is mainly used to treat pain caused by various reasons, and can also be used to promote healing after wound surgery. Its frequency is generally in the low frequency range between 2-160 Hz, the pulse should be short or shorter, and the width is generally between 9-350 μm. transcutaneous electrical nerve stimulation A pulse that is too wide activates pain-transmitting fibers and activa tes ions under the motor, which may make pain worse. The intensity is generally a comfortable intensity, and the afferent nerve response that stimulates proprioception can be selected, and the efferent nerve response that does not trigger movement is mainly used. The current intensity varies in form. Currently, there are dual-current or single-current, bi-directional pulse, and single-wave direction. There is also an asymmetrical bidirectional pulse that can be used with either of these methods. like: What is the main effect of electrical nerve stimulation? ...
