ATPB Amino-terminated polybutadiene (ATPB)
ATPB ke rabara ea polybutadiene e metsi e nang le lihlopha tsa amine lipheletsong tse peli tsa ketane ea limolek'hule. Ha e bapisoa le lihlopha tsa hydroxyl, lebelo la karabelo pakeng tsa lihlopha tsa amine le isocyanate le potlakile, 'me karabelo e potlakile mochesong oa kamore. Eketsa ka ho lekaneng. E ka phekoloa ka sesebelisoa sa ho phekola sa isocyanate kapa ea arabela ka lihlopha tsa epoxy bakeng sa ho phekola.
Thepa e phekotsoeng ea ATPB e na le thepa e ntle ea ho thibela motlakase le thepa ea mechine, haholo-holo ho hanyetsa asiti le alkali, ho hanyetsa ho tsofala, le ho hanyetsa mocheso o tlase.
ATPB e sebediswa haholo bakeng sa dikhomaretsi, dikobo, dikhomaretsi tsa ho etsa dipitsa tsa polyurethane, mabili a polyurethane, di-elastomer tsa polyurethane tse hanelang mocheso o tlase, jj.
E pakiloe ka 50kg/moropa, 170kg/moropa, Nako ea polokelo ke selemo se le seng.
Litaelo tsa polokeho:
Polokelo e lokela ho ba sebakeng se pholileng, se omileng le se nang le moea o kenang. Boemo bo botle ka ho fetisisa ke pakeng tsa -20 ~ 38℃. Nako ea ho boloka ke likhoeli tse 12, haeba e fela, e ntse e sebelisoa haeba e le maemong a tloaelehileng nakong ea tlhahlobo hape. Ha lipalangoang li lokela ho qoba pula, khanya ea letsatsi. U se ke ua kopanya le oxidizer e matla.
