The quartz stone resin content includes 7-12% of all liquid excipients. Less than 7% of toughness is insufficient, easy to break; more than 12% is easy to deform. Many domestic manufacturers have a resin content of about 15%, so it is a fake quartz stone. root
According to different requirements, different formulations are determined; different formulations have different properties of the resin. The resin on the market is a general-purpose resin. Unless you have special requirements and engineers know the resin well.
From saturated dibasic acid: o-phenyl resin and m-phenylene resin. The general-purpose resin is 100% o-phenyl resin, the so-called meta-phenyl resin does not have 100% excluding o-benzene, and the heat-resistant resin is mostly m-phenylene resin.
Divided from diol: general purpose resin and special resin. General-purpose resin --- propylene glycol, ethylene glycol, diethylene glycol three or one or two kinds of reaction with o-benzene; special resin --- used alcohols are more complex, such as neopentyl glycolWait.
From the monomer: general-purpose resin - monomer 100% with styrene; special resin - more complex. The so-called composite acrylic resin on the market is to add 10% or less of methyl methacrylate (MMA) to the general-purpose resin.Instead of part of the styrene, it is not acrylic. Resin resin plexiglass, artificial teeth and other resins. Quartz stone with special requirements is used.
Acrylic resins are available in two manufacturing angles: dissolving acrylic resins and prepolymerized acrylic resins. Generally, the prepolymerized type is better than the dissolved type. Resin is made of quartz stone matrix material in quartz stone plate
Bonding and providing toughness to quartz stone sheets.
There are two main types of resins used in quartz stone: one is an unsaturated polyester resin, and the other is an acrylic resin. However, 100% of domestic manufacturers use unsaturated polyester resin, and acrylic quartz stone does not exist in China.
