What are the differences of natural latex, latex tube in the raw material of synthetic latex and synthetic latex?
What are the differences of natural latex, latex tube in the raw material of synthetic latex and synthetic latex? Latex tube also has advantages and disadvantages, the advantages and disadvantages of raw materials mainly depends on the latex tube. Raw material latex tube there are three main sources: natural latex, synthetic latex and synthetic latex. Then what is the difference between them? Below small make up between the detailed introduction of their similarities and differences.
First, natural latex rubber tree tapping is the outflow of the liquid, milky white, the solid content is 30% ~ 40%, the average particle diameter of 1.06 microns rubber. Natural latex rubber containing ingredients fresh 27% - 41.3% (mass), water 44% ~ 70%, protein 0.2% ~ 4.5%, 2% ~ 5% natural resin, sugar 0.36% ~ 4.2%, ash 0.4%. In order to prevent the natural latex because of microbial, enzymatic action and solidification, often adding ammonia and other stabilizers. Natural latex is mainly for the production of sponge products, extrusion products and impregnated product.
Secondly, synthetic latex was prepared by emulsion polymerization, such as polybutadiene latex, styrene butadiene latex. In order to make the solid content reached 40% ~ 70%, first of all to make rubber particles agglomerate into larger particles, and then using methods similar to natural rubber latex concentrate. Synthetic latex is mainly used for carpets, papermaking, textile, printing, coating and adhesives and other industrial sectors.
Artificial latex is a kind of non emulsion polymerization rubber latex. To solution polymerization generation in colloid adding water and surface active agent, so that the rubber particles dispersed in the water, and then vaporizing the solvent to prepare. If the rubber can not be fully dissolved in the solvent, raw rubber and compound material can be exist in the aqueous phase containing emulsifier conditions continue kneading, until the formation of rubber stable aqueous dispersions.
In a word, use of artificial latex and synthetic latex is basically the same. Among the three difference is very big, natural latex not only material made of natural, environmental protection, mattress, good permeability, strong elasticity; synthetic latex is added some chemical products in latex basis; and synthetic latex is derived from oil in the material, the price is low.
