plastic injection tooling/dry compound is in the first substrate coated with a layer of adhesive, classics drying processing, make the adhesive solvent evaporates, adhesive under dry condition, a method of composite and the second substrate to. Plastic is dry type composite substrate in a molten state under one of the most commonly used method of composite, the base material for the film, sheet and other manufactured goods, and coating composite at room temperature.
plastic dry type composite modified with materials: 1. Base material, plastic dry type composite substrate range is very wide, almost include all the base material. 2. Adhesives, choose one-component pressure-sensitive adhesive or two-component polyurethane adhesive, including commonly used two-component polyurethane adhesive.
plastic dry compound modification technology, the processing of base material, adhesive coating, drying, composite, cooling, crimp, maturation and finished products.
substrate processing main purpose is to improve the strength of the base material compound. Adhesive concentration determination of major need according to the amount of glue, glue quantity is the base area of every square metre how many weight of stem base adhesive, glue amount by the factors such as composite materials and end use purposes.
glue dry dry compound modification process is important working procedure, its transparency on composite materials, such as composite strength has direct impact. Within the general drying on the drying tunnel, drying temperature is generally divided into three sections, the temperature gradually increased. Drying effect on how to measure the volume of solvent residual, general requirements amount of residual solvents should be under 10. Using gc-ms residual solvent quantity can measurement and weight measurement method.
composite soon after drying of glue and the first substrate and the second substrate by the composite heating device, a process with the compression joint together. In a composite process mainly pay attention to the two kinds of substrate tension control, composite temperature and composite pressure and other factors.
cooling of the composite material. After the first substrate and the second substrate composite, after cooling on the steel cooling treatment, only can be curled up. Cooling effect: one is to make composite material, ensure the smooth during winding is not wrinkled; The second binder in the composite material is fully cooled, generate more cohesiveness, prevent the base material to produce relative displacement.
composite curing processing. Curing is also known as curing, its purpose is to let the two-component polyurethane adhesive between the main agent and curing agent react adequately, generate mesh structure, thus improve the adhesive strength and heat resistance, etc.
plastic dry compound problems
1. Material transparency problem
2. Material of wrinkling problem
3. Material is the problem of low bonding strength of
