Add 2 ml of CuCl2 solution to the test tube, then add a certain amount of NaOH solution, and shake to obtain a blue-green turbid solution. This turbid liquid was heated to boiling. No signs of decomposition and black formation of CuO were observed. The light green precipitate was basic copper chloride Cu4 (OH) 6Cl2 with very little solubility.

It plays a very important role in the production of tires and rubber products. The development of foreign rubber extruders has experienced plunger-type extruder, screw-type hot-feed extruder, ordinary cold-feed extruder, main and auxiliary thread cold-feed extruder, cold-feed exhaust extrusion Machine, pin cold feed extruder, compound extruder and other stages.
Basic Information
The screw extrusion of silicone rubber extruder mixing rubber is one of the older fields of extrusion technology, which can be traced back to the 19th century. Silicone rubber extruders are significantly different from thermoplastic extruders. First, rubber extrusion is carried out at lower temperatures (up to 130 ° C). Secondly, rubber extrusion is often added to rubber strips (particulates are added only in exceptional cases), and they do not undergo phase changes or a large degree of thickening... less

As early as 1700, Europe printed the first labels for drug and cloth identification. Therefore, labels are now used to mark your product goals and categories or content, such as the keywords you give your goals, which is a tool for you and others to find and locate your goals. Most labels in the printing industry are printed materials that are used to identify the relevant instructions of their products, and most of them are self-adhesive on the back. But there are also some that are not glued when printing, which can also be called labels. The label with glue is commonly called "self-adhesive label". The problem of labeling the instrument after calibration. This is a label that is uniformly regulated by the country (or its own province). The label can clearly explain the details of the instrument after being calibrated.

There are many methods for processing Sheet Metal Parts. Each processing method will produce different stamping parts, such as sheet metal parts stretch processing, bending processing and so on. So, what is the commonly used hardware process when stamping raw materials?

Thermoplastic Vulcanizate (English: Thermoplastic Vulcanizate), TPV for short, Chinese name for Thermoplastic Vulcanized Rubber (English Thermoplastic Rubber), TPR for short, but this name is easily confused with other types of thermoplastic elastomers (English: Thermoplastic Elastomer) Together, because usually thermoplastic elastomers are also called thermoplastic rubbers, especially styrenic elastomers. At least in China at present it seems that "TPR" has become its proper name. When referring to TPR, it means SBS, SEBS Such styrene-based elastomers are thermoplastic elastomers based on the base material, which is inseparable from the large consumption of styrene-based elastomers in the field of consumer and end consumer products.
If the name of the thermoplastic vulcanizate is more detailed, it should be a thermoplastic dynamic vulcanizate (English: Thermoplastic Dyamic Vulcanizate). The word "dynamic" is added to specify the process of producing this thermoplastic... less

And in the face of the lack of this situation of Chinese ANSI B18.2.1 bolt brands, companies must also consider it.

You can explore the differences here.
Similarities and differences
Similarities – Threaded and compression fittings both use threads to help make their connections. However, they use the threads differently.
Differences – Threaded fittings have a 1-piece connection end that is used to connect to port/block. These threads create the seal for the connection with the support of Teflon tape or pipe dope and are manufactured in a tapered, cone-shape. Whereas compression fittings have a 3-piece connection that is tasked with its connection to tubes. Compression ends typically are a parallel shape and instead of sealing on the threads, the seal point is created with the assistance of a ferrule (ring, olive or sleeve) and a compression nut. So in this case,... less
