Door Bolts And Dust Proof Sockets Dust Proof Strike is normally for use with the bottom bolt of flush bolts. The conventional material of Dust Proof Strike are Brass and Stainless Steel 304, and it usually come with Satin Nickel Finish. Whenever the flush bolt retracts, the spring-loaded plunger returns to the floor or threshold level, eliminating the need to clean standard floor strikes.

When using anionic polyacrylamide, you can choose different molecular weight PAM based on your specific needs.
Anionic polyacrylamide is widely used in wastewater treatment across various industries. In this article, we will explore the applications of anionic polyacrylamide and how it can be effectively utilized depending on the application and user requirements. Different molecular weights of PAM are suitable for different scenarios.
1) In industrial wastewater treatment, especially for wastewater containing coarse suspended particles with a positive charge and high concentration, such as steel plant, electroplating, metallurgical, and coal washing wastewater, anionic polyacrylamide proves highly effective. 2) For drinking water treatment, many water plants in China source water from rivers that are low in mud but high in minerals, making the water relatively turbid. Even after sedimentation, the water may not meet quality standards. Adding a flocculant helps clarify the water. While inorganic flocculants are commonly used, they require large dosages, increasing sludge volume. Anionic polyacrylamide, however, uses half the dosage of inorganic agents but achieves much better results—sometimes several times more effective. Our company’s polyacrylamide has a residual monomer level below 0.05%, meeting food-grade standards and approaching international advanced levels. It is non-toxic and ideal for treating drinking water, river water, and water polluted by organic matter. 3) In starch and alcohol plants, anionic polyacrylamide is used to recover lost starch and distiller’s grains. Many starch factories discharge high-starch waste, which harms the environment and wastes resources. By adding PAM, the starch precipitates and can be filtered into a cake. Similarly, alcohol plants use this process to recycle distiller’s grains, achieving significant economic benefits. One of Asia’s largest alcohol plants in Heilongjiang uses PAM as a flocculant for this purpose. 4) It is also used as a water-blocking agent in oil fields for profile control and water shutoff, as well as an oil recovery agent in tertiary oil recovery processes. 5) In papermaking, PAM serves as an auxiliary, acting as a dispersant, wet/dry strength enhancer, retention aid, filter aid, and flocculant for papermaking wastewater.
