Solid surface stone (also known as "artificial marble") is a new kind of composite material, made from unpolyester resin, chips, pigment. adding a small amount of auxiliary agent, through a certain process.
Solid surface stone production process specification
Materials used for solid surface quartz stones: 1.unspolyster resin; 2.ATH; 3.curing agent.
The main process: ingredients, mixing, vacuum, solid, sanding, curing, polishing, inspection, warehousing
Process: mixing the and auxiliary agent with 2min, then putting pigment and continue mixing for 5 minutes then add ATH and curing agent and mixing for 20min under vacuum condition. Then casting to the auto-production line, at this moment, hardness of sheet is 70%, then curing (that is, in the constant temperature within the space between 50 and 80 degrees for 3 to 6 hours). The same color solid surface sheet, curing agent and auxiliary agent should be same, mixing time should also be the same, vacuumizing time will be the same.
