Lub hauv paus ntsiab lus kho ntawm 107 silicone roj hmab yog cov txheej txheem nyuaj uas cuam tshuam nrog cov tshuaj lom neeg thiab kev hloov pauv ntawm cov khoom siv. Lub hauv paus yog nyob rau hauv qhov sib txuas sib txuas ntawm cov roj hmab silicone thiab lub luag haujlwm ntawm tus neeg sawv cev kho.
Ua ntej tshaj plaws, kev sib txuas sib txuas ntawm cov roj hmab silicone yog ib qho tseem ceeb hauv kev kho. Nyob rau hauv cov txheej txheem no, silicon atoms ntawm cov saw molecular ntawm silicone roj hmab react nrog cov nquag hydrogen atoms nyob rau hauv tus neeg sawv cev kho kom tsim silicon-oxygen bonds thiab disulfide bonds. Kev tsim ntawm silicon-oxygen bonds ua rau kev sib txuas ntawm cov saw hlau molecular ntawm silicone roj hmab, uas ua rau muaj kev sib txuas ntawm peb sab. Cov qauv no tsis tsuas yog txhim kho lub zog ntawm silicone roj hmab, tab sis kuj txhim kho nws elasticity. Kev tsim cov ntawv cog lus disulfide txuas ntxiv ua rau kev sib txuas ntawm tus neeg sawv cev kho thiab ua kom nrawm nrawm ntawm silicone roj hmab.
Hauv 107 silicone roj hmab, feem ntau siv cov tshuaj tua kab mob feem ntau yog diethylmercaptan (DET) thiab dimethylmercaptan (DMS). Thaum cov tshuaj tua kab mob no ntxiv rau cov roj hmab silicone, cov active hydrogen atoms nyob rau hauv tus neeg sawv cev curing react nrog cov silicon atoms ntawm cov saw molecular ntawm silicone roj hmab los tsim sulfur-silicon bonds. Qhov tsim ntawm no sulfur-silicon daim ntawv cog lus ua rau kev sib txuas ntxiv ntawm cov saw hlau molecular ntawm silicone roj hmab, uas hloov cov roj hmab silicone los ntawm cov kua hauv lub xeev mus rau lub xeev ruaj khov.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias tus nqi ntawm tus neeg sawv cev kho tau ntxiv thiab qhov kho qhov kub thiab txias yog qhov tseem ceeb uas cuam tshuam rau qhov curing ceev thiab curing nyhuv. Qhov zoo ntawm tus neeg saib xyuas kho thiab qhov kub kho kom raug tuaj yeem ua kom ntseeg tau tias cov roj hmab silicone tau kho tag nrho thiab ua tiav qhov kev xav tau.
Tsis tas li ntawd, cov txheej txheem kho ntawm 107 silicone roj hmab cuam tshuam nrog cov tshuaj tiv thaiv polymerization, diffusion, thiab thermodynamic tsav tsheb thiab kev tswj kinetic. Cov tshuaj tiv thaiv polymerization ua rau cov monomeric molecules khi rau hauv cov saw ntev, cov txheej txheem diffusion ua rau cov molecules rov kho dua hauv cov khoom, thiab cov thermodynamic tsav tsheb thiab kev tswj kinetic cuam tshuam rau tag nrho cov txheej txheem kho.
Zuag qhia tag nrho, lub hauv paus ntsiab lus kho ntawm 107 silicone roj hmab yog cov txheej txheem tshuaj lom neeg cov tshuaj tiv thaiv, los ntawm kev sib txuas cov tshuaj tiv thaiv thiab kev ua ntawm tus neeg sawv cev kho, cov roj hmab silicone muaj peev xwm hloov tau los ntawm cov kua hauv lub xeev mus rau lub xeev ruaj khov, thiab nthuav tawm lub cev zoo thiab tshuaj muaj zog.
