Then after a long time of use, it will inevitably adsorb some dust or oil on the ANSI B18.2.1 bolts. If it is left untreated for a long time, it will easily cause corrosion. The daily cleaning work is particularly important, but the ANSI B18.2.1 bolts are properly cleaned Do you really know the method?

The main materials of rubber products are raw rubber, compounding agents, fiber materials and metal materials. Raw rubber is the basic material; compounding agents are auxiliary materials added to improve certain properties of rubber products; fiber materials (cotton, hemp, wool and various artificial fibers, synthetic fibers) and metal materials (steel wire, copper wire) It is used as the skeleton material of rubber products to enhance mechanical strength and limit product variations.
In the raw material preparation process, the ingredients must be accurately weighed according to the formula. In order to make the raw rubber and the compounding agent evenly mix with each other, some materials need to be processed:
The raw rubber should be softened in a 60-70C drying room, and then cut and broken into small pieces;
The bulk compound such as paraffin, stearic acid, rosin, etc. must be crushed;
If the powdery compound contains mechanical impurities or coarse particles, it needs... less

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.
