Cov khoom loj thiab cov yam ntxwv ntawm cov khoom siv silicone

1. Txwv qhov loj: 15 ~ 20MM tuaj yeem ua tiav ntawm qhov chaw thickest. Yog tias nws yog tus kheej, nws tuaj yeem yog 30 hli diam. Cov lus pom zoo tuab rau cov tuab tuab tsis tshaj 3MM. Thaum nws loj dua 3MM, nws yuav siv nyiaj ntau dua lub sijhawm ua haujlwm thiab nce tus nqi. Kev ua cov khoom thinnest tuaj yeem ncav cuag 0.2MM, tab sis cov qauv siv feem ntau yog qhov thinnest 0.3MM, 0.4MM pom zoo.

2, tus txheeb ze qhov loj me: hauv cov tuab sib txawv, qhov sib txawv thiab qhov tuab tshaj yog pom zoo kom tsis txhob ntau tshaj 3 zaug. Cov teeb meem zoo li no feem ntau yog txiav txim siab los ntawm qhov kub thiab siab qhov xav tau ntawm cov khoom siv vulcanization.

3. Txo tus nqi: Lub shrinkage tus nqi ntawm cov khoom siv silica gel muaj feem xyuam rau lub hardness ntawm cov khoom. Cov khoom siv theem nrab los ntawm cov khw yog feem ntau ntawm 1.022 txog 1.042. Rau cov khoom siv nrog 40 txog 50 qib, qhov shrinkage tus nqi ntawm 1.03 feem ntau noj. Piv nrog rau plastics, cov khoom lag luam silicone tsis tsim cov tsis zoo li thaj chaw tsis xws luag vim shrinkage.

4, ntsuas qhov tseeb: Vim tias cov khoom lag luam silicone feem ntau yog ntau lub qhov, tus lej ntawm qhov txheeb ze rau cov khoom yas yog ntau heev. Yog li ntawd, tsis muaj qhov yooj yim hauv kev tswj hwm qhov loj ntawm cov khoom yas. Qhov tseeb ntawm qhov tseeb yog ntxiv lossis rho tawm 0.1, thiab cov khoom lag luam siab yog ntxiv lossis rho tawm 0.05. Thaum qhov siv tau los siv rau qhov haum ntawm qhov lub qhov thiab khawm ntawm cov feem yas, qhov sib txawv tsawg kawg yog 0.1, thiab tus nqi pom zoo yog 0.2 ntawm ib sab.

5. Cov qauv tsim: Rau cov tes tsho ntawm cov roj hmab, cov kos duab qub tuaj yeem muab rau lub Hoobkas pwm raws li cov phiaj xwm txheej txheem ntawm cov khoom. Cov teeb meem ntawm cov txuam yog piav qhia los ntawm lub Hoobkas pwm. Nyob rau hauv ib txwm muaj xwm txheej, nyob ntawm seb qhov loj me li cas, qhov haum ntawm lub tes tsho roj hmab rau cov khoom lag luam feem ntau muaj qhov tsis zoo ntawm 0.2 txog 0.5 ntawm ib sab.
