Ntiaj teb Silicone network qhia thaum Lub Ib Hlis 16: Xws li cov pob zeb uas muaj cov roj av uas muaj pob zeb, thiab cov roj ntsha yas (si-vinyl Silicone Resin, thiab lwm yam) thiab Si -H Hydrogen-muaj cov roj polymers (xws li hydrogen-muaj cov tshuaj tiv thaiv Silicone)
Piv nrog lwm cov ntaub ntawv polymer, platinum vulcanized silicone roj hmab muaj cov txheej txheem uas tsis muaj zog, muaj kev nyab xeeb thiab ib puag ncig molding, luvfib ntawm Automation, lub zog zoo ntawm cov khoom tiav, pob tshab, yooj yim mus kom dav siv cov khoom noj thiab cov tawv nqaij (silicone tsheb silicone ua npuas thiab lwm daim teb.
Ntxiv rau-hom silicone, platinum catalyst yuav tsum tau ntxiv ua kom cov hydrosilylation cov yeeb yam mus. Txawm li cas los xij, kev ua si ntawm platinum catalyst yog siab heev. Tom qab sib tov nrog vinyl polymer thiab hydrogen-muaj polymer, lub sijhawm ua haujlwm yog luv heev. Kev hla kev sib txuas yuav tshwm sim sai li cas hauv ob peb feeb lossis feeb, ua rau cov roj hmab uas tawv ntawm cov roj hmab silicone lossis tsis tuaj yeem siv roj hmab. Yog li ntawd, nws yog feem ntau tsim nyog los ntxiv inibitors (retarders) rau tus qauv los kho cov tshuaj kho kom nrawm.
Tus txheej txheem ua haujlwm ntawm tus kws muaj kev sib koom tes yog tsim ib txoj kev sib koom ua ke nrog cov platinum catalyst nyob rau hauv chav sib koom tes los tiv thaiv kev sib koom tes ntawm Si-H thiab SI-VI; Tom qab muab cua sov kom muaj qhov kub thiab txias, kev ua haujlwm sib cog lus tsis muaj zog lossis decomposes, rov kho dua cov kev ua si ntawm cov platinum catalyst, thiab Si-H thiab SI-VI tuaj yeem tshwm sim sai. Ntau dua inibitors tau ntxiv, qhov zoo dua qub inhibitions cov nyhuv zoo thiab siv sijhawm ntev dua, tab sis ceev volcanization ceev yuav kuj ua kom qeeb.
Qhov feem ntau siv siv inhibitor hauv kev lag luam silicone yog EthyNy beadition 30} Lub ntsej muag me me: 124O, muaju kub, thiab cov muaju dawb ntawm cov kub. EthyYL Cyclohexanol muaj qhov zoo ntawm cov neeg nyob hauv tsev loj loj, cov nqi ntxiv, siv tau muaj zog, thiab tus nqi tsawg. Nws yog dav siv hauv kev sib xws platinum vulcanized silicone roj hmab thiab khoom noj, tus menyuam, cov neeg siv khoom, cov neeg siv khoom thiab lwm yam khoom lag luam.
Txawm li cas los xij, Ethynnyl cyclohexanol kuj muaj qee qhov tsis zoo:
1. Nws yog ib qho yooj yim kom khov nyob rau lub caij nplooj zeeg thiab lub caij ntuj no, uas yog tsis yooj yim siv;
2. Tseem tshuav ib qho me me ntawm cov ntxhiab tsw;
3. Lub sijhawm cia khoom ntawm cov khoom npaj roj hmab ntawm chav tsev kub tsis zoo;
4. Platinum extruded Silicone roj hmab khoom uas yog vulcanized los ntawm huab cua kub yog tus siv cov npuas.
