What is the solvent?
The solvent cement brings the thermoplastic leaves and the pipe by softening the surface of the connected material. Unlike the sticking, which solidifies the material together, the material softened with cement cement trades molecules to form a welded solvent that has the power of the superior material. Primers and proper preparation allow the solvent to create a binding without contamination from grease, inks and oils. In addition to proper cleaning, the type of cement of the solvent compatible with thermoplastic or plastic surface will be melted correctly and the joint will not have a strong bond. The designation of the three letters listed on the canister label must correspond to the designation of the three letters printed on the thermoplastic surface to ensure that the finished welded joint has the power to maintain the amount of pressure required from the connection. Conventional three -girds plastic identification are polyvinyl chloride (PVC), chlorinated polyvinyl chloride (CPVC) and acrylonitril -butadien styren (ABS). One thing that has common cements of thermoplastic meltsYou are strong fumes emitted from the chemical during use.
The chemicals used to soften the surface of three conventional thermoplastics have a strong odor that can become overwhelmed in limited areas in which they are used. Proper ventilation ensures a constant flow of fresh air that prevents the construction of solvent in the area and reduces the chances of a solvent user that succumbs to asphyxiation. When the canister of the solvent is opened and a strong odor cannot be felt, the liquid cement inside the container can be dried or frozen at once.
The common symptoms that the cement has deteriorated is a gel consistency, lumps hovering inside a container or a dauber that cannot be remaped from the canister. Unlike colors or other solvent -based materials, the solvents cannot be reduced to bring them back to their original consistency. Dilution of solvent cement sonsObviously, solvents are used to soften the surface of the plastic to disintegrate and not allow for a strong binding to create between pieces of material. Cooling is another factor that inhibits the ability of cement to connect plastic. The optimum temperature for the application of the solvent cement to the thermoplastic will be printed on the canister label and the product should not be applied at temperatures sitting outside the optimum temperature range.
