Kev siv kub ntau ntawm platinum catalyst

Kev siv kub ntau ntawm platinum catalyst yog qhov dav, tab sis qhov tshwj xeeb yuav txawv me ntsis nyob ntawm qhov sib txawv daim ntawv thov scenarios thiab cov qauv silicone:
General kub ntau yam:
Raws li ib txwm muaj, platinum catalyst tuaj yeem kho cov kua silicone ntawm chav tsev kub (kwv yees li 20 degree -25 degree), tab sis qhov kev kho ceev kuj qeeb. Nyob rau hauv chav tsev kub, nyob ntawm seb tus qauv ntawm silicone thiab tus nqi ntawm cov catalyst ntxiv, nws yuav siv sij hawm ob peb teev los yog ntev dua los kho tag nrho.
Tom qab cua sov, qhov curing ceev yuav ceev heev. Feem ntau hais lus, kua silicone tuaj yeem kho tau hauv lub sijhawm luv dua nyob rau hauv qhov kub ntawm 60 degree -150 degree . Piv txwv li, ntawm qhov kub ntawm txog 100 degree -120 degree, nws tsuas yog siv kaum feeb kom ua tiav cov txiaj ntsig zoo.
Qhov kub tshwj xeeb:
Hauv qee daim ntawv thov tshwj xeeb, qhov kub ntawm platinum catalyst yuav dav dua. Piv txwv li, qee cov khoom tsim tshwj xeeb platinum curing silicone cov khoom tseem tuaj yeem tswj tau qee qhov kev kho kom zoo ntawm qhov kub qis ntawm -60 degree , thiab tseem tuaj yeem tswj nws qhov kev ua tau zoo tom qab kho qhov kub ntawm 250 degree lossis siab dua. Txawm li cas los xij, qhov no tsuas yog qhov ua tau zoo nyob rau hauv cov xwm txheej tshwj xeeb. Qhov tshwj xeeb kev khiav hauj lwm qhov kub thiab txias yuav tsum tau txiav txim siab raws li cov kev cai tshwj xeeb ntawm cov khoom thiab kev sim tiag tiag.
