Silica gel tau siv dav hauv kev ua lag luam vim nws tsis tso cov tshuaj lom, muaj qhov muag muag thiab xis nyob, thiab muaj lub cev zoo thiab tshuaj lom neeg ntawm qhov kub thiab txias (-60c ~ + 300c). Muaj ob peb lwm cov polymers uas tuaj yeem phim nws.
Muaj zog elastomer, zoo dua li cov roj hmab sealing, zoo heev hluav taws xob rwb thaiv tsev, thiab tiv thaiv cov tshuaj, fuels, roj, thiab dej, ib tug zoo cov ntaub ntawv los tiv thaiv tej yam tsis zoo.
Hauv kev lag luam, xws li roj foob, cov yuam sij keyboard, cov khoom siv hluav taws xob rwb thaiv tsev, cov khoom siv hauv tsheb, cov khoom siv niaj hnub xws li pacifiers, catheters dag, lub tshuab ua pa, qag iav, tawv khau thiab khau ntaub, ntim khoom noj, thiab lwm yam.
Yog tias koj muaj qee qhov sliicone xav tau kev tsim khoom, tsuas yog hu rau peb kom tau txais kev paub ntau ntxiv.
Dab tsi yog qhov sib txawv ntawm cov kua silica gel thiab cov khoom silica gel?
Silicone kua
Liquid silica gel yog ib hom khoom kub-kub vulcanized silicone roj hmab. Nws yog cov kua gel nrog zoo fluidity, ceev vulcanization, kev nyab xeeb thiab kev tiv thaiv ib puag ncig, thiab tuaj yeem ua tau raws li cov kev cai ntawm qib zaub mov.
Khoom siv silica gel
Cov khoom siv silica gel yog ib yam khoom siv saturated polymer elastic, uas muaj cov yam ntxwv ntawm qhov kub thiab txias, tiv taus txias, hnyav ua haujlwm, tiv thaiv kev tiv thaiv, tiv thaiv nplaum, hluav taws xob rwb thaiv tsev, tshuaj tiv thaiv thiab muaj ntau yam kev thov.
1. Cov kua silica gel thiab cov khoom zoo li qub
(1) Raws li lub npe implies, kua silica gel yog kua thiab muaj liquidity
(2) Cov khoom silica gel yog khoom, tsis muaj kuab lom!
2. Kev siv cov kua silica gel thiab cov khoom silica gel
(1) Cov kua silica gel feem ntau yog siv rau hauv cov khoom me me, cov khoom siv hauv chav ua noj, thiab cov khoom siv kho mob, uas tuaj yeem tiv tauj cov zaub mov thiab tib neeg lub cev.
(2) Cov khoom siv silica gel feem ntau yog siv rau hauv cov khoom siv niaj hnub thiab cov khoom lag luam thiab cov khoom pib, thiab lwm yam., daim ntawv thov ntau yam kuj dav.
3. Kev nyab xeeb ntawm cov khoom silica gel thiab kua silica gel
(1) Cov kua silica gel yog cov pob tshab thiab cov khoom noj khoom haus muaj kev nyab xeeb siab, molding tsis ntxiv vulcanizing tus neeg saib xyuas thiab lwm yam khoom siv pabcuam, ntim khoom noj molding.
(2) Cov khoom siv silica gel yog cov khoom siv tiv thaiv ib puag ncig pob tshab, kev tsim cov khoom yuav tsum tau ntxiv tus neeg saib xyuas kom ua kom lub sijhawm kho kom zoo, thiab qhib pwm pub molding.
4. Ua kua silica gel thiab khoom silica gel molding txoj kev
(1) Cov kua silicone yog txhaj tshuaj molding kua silicone roj hmab (LSR): tag nrho lub npe rau kev txhaj tshuaj molding kua silicone roj hmab, kho cov cuab yeej rau kev txhaj tshuaj molding tshuab.
Kev txhaj tshuaj molding tshuab muaj cov txheej txheem thev naus laus zis uas yooj yim heev, tsis tas yuav yog cov txheej txheem ntawm cov khoom siv kua nplaum kub kub, sib tov, blanking, cov khoom siv thiab cov txheej txheem, tsuas yog ib tus neeg ua haujlwm coj cov khoom), cov khoom lag luam siab (hmoov molding ua ntej tag nrho. phau ntawv kev pab cuam yuav hloov los ntawm A tshuab), siab tso zis (A / B kua nplaum sib tov, nyob rau hauv ib tug tej yam kub rau ib tug ob peb vib nas this kom zoo), txuag, txuag hluav taws xob, txuag cov ntaub ntawv thiab lwm yam zoo, muaj peev xwm tsim tag nrho cov kub-kub kua nplaum. cov khoom tsim tawm! Nws yog ib qho tseem ceeb ntawm silicone roj hmab cov ntaub ntawv kev loj hlob nyob rau hauv ob peb xyoos tom ntej no.
(2) Cov khoom siv silica gel molding yog cov khoom siv raw uas yog ib qho ntawm cov khoom, los ntawm kev sib xyaw tshuab sib xyaw, lub tshuab txiav yog txiav rau hauv cov khoom thiab txhaj pwm qhov tsim nyog loj thiab tuab, thiab tom qab ntawd mus rau hauv pwm, siab molding tshuab hauv qab. ib qho kub molding. Demoulding thiab cov khoom yas txog tib yam, kuj yuav tsum tau ntxuav cov pwm.
5. Cov khoom ua kua silica gel thiab cov khoom siv silica gel yuav ua li cas kom paub qhov txawv
Cov kua silica gel pob tshab yog siab, tsis muaj ntxhiab tsw, thiab cov khoom muaj lub qhov ncauj txhaj tshuaj kua nplaum. Khoom ntxhib pore silica gel pob tshab hauv qab, vulcanizing tus neeg saib xyuas lossis lwm lub npog vulcanizing tus neeg sawv cev tshuaj tsw qab, ib yam khoom tsis muaj qhov ncauj txhaj
