Cov kua roj hmab ntxiv yog ua raws li polydimethylsiloxane uas muaj cov yas, thiab polyorganosiloxane muaj ntau Si-H daim ntawv cog lus raws li tus neeg sawv cev sib txuas. Nyob rau hauv qhov kev txiav txim ntawm platinum catalyst, qhov sib ntxiv cov tshuaj tiv thaiv yog nqa tawm nyob rau hauv chav tsev kub los yog cua sov kom tau txais peb-dimensional cross-linked qauv ntawm silicone roj hmab. Cov tshuaj tiv thaiv mis yog qhia raws li hauv qab no:
Nyob rau hauv daim ntawv thov ntawm ob lub ntsiab additive hom kua silicone roj hmab, thaum ob lub Cheebtsam yog tov, nws xav tau ib tug tsim nyog lub sij hawm khiav hauj lwm ntawm chav tsev kub. Lub sij hawm ntev dhau lawm, vulcanization qeeb dhau, yog khi kom txo cov kev ua haujlwm ntau lawm; Thiab lub sijhawm luv luv, kev tsim kho yog nruj, tab sis kuj ua rau cov khoom siv roj hmab pov tseg. Rau ib qho khoom siv ntxiv ua kua silicone roj hmab, nws yuav tsum muaj kev ruaj ntseg ntawm chav tsev kub, tuaj yeem khaws cia rau lub sijhawm ntev. Tab sis thaum nws nce mus rau qhov kub thiab txias, nws tuaj yeem ua tau sai vulcanized. Yog li, txhawm rau ua kom tau raws li daim ntawv thov, feem ntau yuav tsum tau ntxiv cov tshuaj tiv thaiv kab mob (xws li alkynyl cawv thiab vinyl siloxane, thiab lwm yam). Tshwj xeeb, txhawm rau ua tiav qhov kev hloov pauv mus rau ib qho yooj yim dua ib qho colloids, micro encapsulated platinum catalyst tau tsim, uas yog, platinum catalyst yog encapsulated nyob rau hauv ib tug tsawg softening point (50-200 degree) resin (xws li. organic resin thiab silicone resin), thiab qhov loj ntawm cov tshuaj ntsiav yog tsawg dua 100μM. Nyob rau hauv chav tsev kub los yog kub tsis tshua muaj, vim yog kev sib cais ntawm platinum, tsis tuaj yeem ua lub luag haujlwm catalytic, thaum kub nce siab tshaj qhov muag ntawm cov resin, platinum catalyst raug tso tawm, yog li catalyzing ntxiv cov tshuaj tiv thaiv, hla kev txuas mus rau elastomer.
