plz tell it in about 1000 words full detail be clearCan Any1 tell me the processing of rubber after the collection of latex?
After collection of the tapped latex, rubber is recovered from emulsion by coagulation with formic acid, creating crumbs that resemble curds of milk. The crumbs are washed, dried between rolls, and compacted into blocks. The blocks are then wrapped in polyethylene sheets and packed into crates for shipping. Other production is as smoked sheet, where the coagulum is pressed into thin sheets that are washed and then dried over a smoky wood fire. The smoke contains natural fungicides that protect against mold growth and impart a characteristic amber colour. Dried sheets are packed into bales for shipping.About 10 percent of all natural rubber is shipped as latex, concentrated to a rubber content of approximately 60 percent and used for making dipped goods such as surgical gloves, prophylactics, and toys. If latex is allowed to evaporate naturally, the film of rubber that forms can be dried and pressed into usable articles such as bottles, shoes, and balls.
