What are the similarities and differences between domestic and imported latex emulsion?
![]()
Latex is generally divided into domestic and imported, generally used as emulsion products. Latex products mainly to do with latex, latex sheet, latex belt etc.. The similarities and differences between domestic and imported latex emulsion is very simple is a centrifugal and two centrifugal problem. Below small make up a detailed explanation of the similarities and differences between domestic and imported latex emulsion.
Two centrifugal imported latex
According to the characteristics of rubber material latex most distributed in the whey phase and small particles of non more glue matter content, ammonia preserved fresh latex first centrifugal time, add about one times of water diluted the centrifuged rubber latex, and then the second centrifugal, further remove non rubber substance. Latex concentrate income, save with 0.7% ammonia, called two centrifuged rubber latex. The latex total dry difference is less than a half of the centrifuged rubber latex. But after two times of centrifugal retained after stabilizing protein and soap are still above 60%, which shows that most of the binding protein and soap in the rubber phase. After the two centrifuge enrichment, to the stability of components such as non-volatile acid group, carbonate / bicarbonate and volatile fatty acid is substantially reduced 1/3. Potassium concentration also reduced. Two centrifugal not to reduce the extent of the corresponding KOH value, this is because the whey in latex soap hardly transferred to be separated and loss. Two centrifugal latex film low water absorption, film colour, with electrical insulation and good biological inert,
A centrifugal domestic latex
According to the characteristics of rubber material latex most distributed in the whey phase and small particles of non more glue matter content, ammonia preserved fresh latex centrifugal time
The similarities and differences between domestic and imported above is emulsion latex, latex using imported two centrifugation, domestic latex is a centrifugal, compared with domestic latex containing fewer impurities, good stability.
Can be used for making rubber than pure products, such as electrician gloves, surgical operation activities, such as condoms.
