diphenylphosphineoxide CAS:4559-70-0

Diphenylphosphineoxide e sebetsa e le karolo ea bohlokoa tlhahisong ea lintho tse thibelang malakabe bakeng sa li-polymer, masela le thepa ea kaho. Ho kenyelletsoa ha eona mefuteng ea lintho tse thibelang malakabe ho tšehetsa nts'etsopele ea thepa ka khanyetso e matla ea mollo, ho thibela mosi le botsitso ba mocheso, ka hona ho netefatsa polokeho le ho latela melaoana ea ho thibela malakabe lits'ebetsong tse fapaneng. Bokhoni ba motsoako ba ho sitisa ts'ebetso ea ho tuka bo etsa hore e be karolo ea bohlokoa mahlaleng a thibelang malakabe ho pholletsa le liindasteri. Lefapheng la tlhahiso ea lintho tse phelang, Diphenylphosphineoxide e sebelisoa e le sesebelisoa se feto-fetohang bakeng sa phetoho ea limolek'hule tsa lintho tse phelang le ho thehoa ha meaho e rarahaneng ea lik'hemik'hale. Ho arabela ha eona ho nolofalletsa ho hlahisoa ha lihlopha tse sebetsang tse nang le phosphorus, ho nolofalletsa ho kopanngoa ha lik'hemik'hale tse ikhethang, metsoako ea meriana le metsoako ea temo. Karolo ea motsoako phetohong ea lintho tse phelang le ho hlahlobisisa e kenya letsoho tsoelo-peleng ea tlhahiso ea lik'hemik'hale le nts'etsopele ea thepa e ncha e nang le thepa e etselitsoeng eona. Ho feta moo, motsoako o bapala karolo ea bohlokoa e le setsibi le antioxidant indastering ea polymer. Bokhoni ba eona ba ho senya li-free radical le ho thibela liketso tsa oxidation bo thusa ho boloka thepa ea thepa, bo eketsa bophelo ba tšebeletso le ts'ebetso ea thepa ea polymer e sebelisoang likoloing, kahong le thepa ea bareki. Ho feta moo, Diphenylphosphineoxide e sebetsa e le thuso ea ts'ebetso le ho tsamaisana le metsoako ea polymer, e ntlafatsa ho lumellana le thepa ea mechini ea litsamaiso tsa polymer tse tsoakiloeng, e tlatsetsa nts'etsopele ea thepa e ncha e nang le litšobotsi tse ntlafetseng tsa ts'ebetso. Ho feta moo, motsoako ona o sebelisoa ho etseng li-additives tse khethehileng bakeng sa li-lubricant, maro a sebetsang ka tšepe le li-coat tsa indasteri. Maro a eona a lik'hemik'hale a nolofalletsa ho thehoa ha li-additives tse sebetsang hantle tse ntlafatsang ho tlotsa, tšireletso ea mafome, le botsitso ba mocheso lits'ebetsong tse fapaneng tsa indasteri. Ka ho ntlafatsa ts'ebetso ea maro ana le li-coat, Diphenylphosphineoxide e thusa ho etseng hantle le ho tšoarella ha mechine, likarolo le libaka ho pholletsa le makala a fapaneng a indasteri. Ka bokhutšoanyane, Diphenylphosphineoxide e bontša ts'ebeliso ea eona e pharaletseng e le motsoako o feto-fetohang o nang le lits'ebetso tse fapaneng ho pholletsa le liindasteri, ho kenyeletsoa le li-retant tsa malakabe, tlhahiso ea organic, li-additives tsa polymer, le lik'hemik'hale tse ikhethang. Sebopeho sa eona se ikhethang sa limolek'hule le reactivity li thusa ho ntlafatseng le tsoelo-pele ea saense ea thepa, boenjiniere ba lik'hemik'hale le lits'ebetso tsa indasteri.
