Bakelite powder is a common new material and has good applications in many aspects. There are also many bakelite powder manufacturers. In order to survive in the industry, how can Zhejiang bakelite powder manufacturers improve the quality and production process of bakelite powder? It has become a problem that many manufacturers need to pay attention to.

The influence of the size change of the bakelite cage during the oil immersion process on the processing size of the process size, reasonable preparation of each process and analysis of the processing points and difficulties of some processes to obtain stable process size and accuracy

Bakelite powder, also known as bakelite powder, has good insulation properties and is used to manufacture electrical appliances and daily industrial products. It is a phenolic plastic mainly made of wood powder as a filler, which is made by pressing.

When the formaldehyde/phenol (molar ratio) is less than 1, a thermoplastic product can be obtained, called a thermoplastic phenolic resin, that is, a novolak phenolic resin, which does not contain further polycondensation groups, and can be cured by adding a curing agent and heating. For example, using hexamethylenetetramine as the curing agent, the curing temperature is 150 ℃, and the molding powder mixed with filler is commonly known as bakelite powder. When the formaldehyde/phenol (molar ratio) is greater than 1, first-stage resin, ie thermosetting phenolic resin, can be obtained under alkali catalysis, which can be dissolved in organic solvents. The first-stage resin contains hydroxymethyl which can be further polycondensed, so no It can be cured by adding a curing agent: the B-stage resin is obtained by reaction under heating, also known as semi-soluble phenolic resin, which is insoluble and infusible but can swell and soften.
