The processing steps of hydraulic prop are less, the surface adjustment process can be omitted, and the tank liquid can be reused.
Effectively improve the adhesion of steel acrow props paint to substrate. It can deal with many kinds of substrates such as iron sheet, galvanized sheet, aluminum sheet, etc. In the 1990s, the United States began to carry out theoretical research on the pretreatment technology of metal silane, and in the mid-1990s, Europe began to carry out exploratory research on silane.
At the beginning of this century, major research institutions and production enterprises in China began to study silane. There are also projects to turn waste into treasure and protect the ecological environment. Leading production technology of QY biodiesel at home and abroad;
The hydraulic prop invented by China Coal Group Co., Ltd. has the characteristics of excellent chemical stability, acid and alkali resistance and microbial erosion resistance. Real time temperature display, time decreasing display, double time and temperature setting, acrow prop automatic fault detection and buzzer alarm function. Temperature deviation calibration function, convenient module replacement, easy to clean and disinfect, built-in over temperature protection device, blue LCD display, membrane switch.
Silane contains two different chemical functional groups, one end can react with hydroxyl groups on the surface of inorganic materials (such as glass fiber, silicate, metal and its oxide) to form covalent bond, the other end can form covalent bond with resin, so as to combine the two materials with very different properties. Silylation is a process of surface treatment of metal or nonmetal materials with organosilane as the main raw material. Compared with traditional phosphating, silylation has the following advantages: no harmful heavy metal ions, no phosphorus, no heating of monomer steel acrow props. The process of silane treatment does not produce sediment, the treatment time is short and the control is simple.
