MST produces building grade HPMC, which is an important building material and plays an important role in building materials. Building grade HPMC has good water retention: building grade HPMC can significantly reduce the water absorbed by the wall and has good water retention. On the one hand, it can ensure that the cement has a longer compounding time. On the other hand, it can ensure that workers can scrape the putty on the wall multiple times. To ensure the quality of building.

ZnO should be an insulator at room temperature. ZnO is decomposed at high temperature. Excessive zinc enters the gap due to ionization, forming interstitial ions, causing shared movement of electrons in the structure, forming an n-type semiconductor, which is an important raw material for the production of zinc oxide varistors.
