Cov kev sib tsoo tshwj xeeb (ceev) ntawm kev txhaj tshuaj silicone yog feem ntau cuam tshuam nrog cov hauv qab no:
Ntaus thiab cov ntsiab lus ntawm lub hauv paus polymer:
Lub hauv paus polymer ntawm cov tshuaj txhuam silicone yog nws lub ntsiab tivthaiv, thiab ntau hom polymers muaj ntau qhov sib txawv. Yog li ntawd, kev xaiv ntawm lub hauv paus polymer thiab nws cov ntsiab lus yuav cuam tshuam ncaj qha cuam tshuam rau cov kev nqus tau ntawm cov nqus ntawm silicone. Piv txwv li, qee qhov hnyav molecular phaus polymers muaj ntau dua, yog li nce cov kev nqus tshwj xeeb ntawm silicone.
Hom thiab tus nqi ntawm cov tub lim ntxiv:
Cov fitters yog cov siv sib xyaw ua ke hauv kev txhaj tshuaj silicone los kho cov yam ntxwv ntawm silicone. Cov hom muab tub lim (xws li cov carbon dub dub, diatomaceous ntiaj teb, thiab lwm yam) thiab tus nqi ntxiv yuav cuam tshuam qhov tshwj xeeb ntawm kev sib nqus ntawm silicone. Qhov kev sib ntxiv ntawm cov tuab tuab tuab yuav nce cov kev nqus tshwj xeeb ntawm silicone, thaum ntxiv ntawm cov chav ua haujlwm tsawg yuav txo cov kev sib tsoo.
Crosslinking ntom:
Kev txhaj tshuaj silicone yuav ua rau tus qauv sib txuas thaum lub sijhawm ua kom muaj kev sib cav, thiab cov kev sib cav sib ceg tseem yuav cuam tshuam cov kev sib tsoo ntawm silicone. Feem ntau hais lus, siab dua tus ntoo khaub lig ntom ntom ntom ntom, lub tig rov qab cov intermolecular bonding ntawm silicone, uas tej zaum yuav ua rau muaj kev nce ntxiv hauv kev sib nqus. Txawm li cas los xij, cov nyhuv no tsis yog linear, vim tias qhov nce hauv kev ntom ntom ntom ntom tej zaum kuj yuav hloov lwm yam khoom ntawm silicone.
Sib tov thiab vulcanization txheej txheem:
Qhov kub thiab txias, lub sijhawm, sib xyaw ua ke thiab lwm yam kev sib xyaw ua ke hauv cov txheej txheem sib xyaw, thiab cov txheej txheem kub, yuav muaj qee qhov cuam tshuam ntawm kev sib tsoo ntawm silicone. Cov txheej txheem no yuav cuam tshuam cov qauv molecular thiab kev npaj sab hauv ntawm silicone, yog li tsis ncaj rau nws lub ntiajteb txawj nqus.
Ntxiv thiab auxiliaries:
Ua kua muag silicone kuj tseem tuaj yeem muaj ntau yam tshuaj ntxiv thiab cov tshuaj txhuam, antioxidants, thiab lwm yam ntawm cov khoom sib xyaw ntawm silicone, txawm hais tias cov nyhuv no feem ntau yog me me.
Hauv cov ntsiab lus, cov kev sib nqus tshwj xeeb ntawm cov kua muag silicone cuam tshuam los ntawm ntau yam, nrog rau cov khoom siv sib xyaw, cov txheej txheem sib xyaw, thiab cov quav ntxiv thiab cov zauv. Hauv kev siv cov kev siv, nws yog ib qho tsim nyog los xaiv cov txheej txheem raw thiab cov txheej txheem ntau lawm raws li cov kev xav tau thiab cov khoom siv ua kom zoo tshaj plaws nrog cov kev nqus kom zoo tshaj plaws.
