Los ntawm kev xav ntawm kev siv cov khoom siv silicone, cov khoom ua los ntawm cov khoom tsis muaj tshuaj lom, tsis muaj ntxhiab thiab tsis muaj teeb meem silicone yog cov khoom zoo.
Hom silicone no yog hu ua ntxiv-hom silicone, platinum-catalyzed silicone lossis khoom noj khoom haus-qib silicone hauv kev lag luam.
Tam sim no, muaj ob hom kua silicone roj hmab ntawm lub khw. ib qho yog thawj cov khoom lag luam hauv kev lag luam silicone roj hmab-condensed silicone roj hmab (organic tin-catalyzed industrial silicone roj hmab), thiab lwm yam yog vim muaj kev tiv thaiv ib puag ncig ntawm lub teb chaws nyob rau xyoo tas los no. , thiab cov kev tshawb fawb thiab tsim ntxiv-hom silicone roj hmab (platinum catalysis); ntau hom silicone roj hmab yog siv nyob rau hauv cov khoom sib txawv, yog tias muaj hom silicone roj hmab siv nyob rau hauv lub teb ntawm ntxiv-hom silicone roj hmab, nws yuav ua rau muaj kev puas tsuaj rau tib neeg lub cev; Tom qab ntawd yuav ua li cas kom paub qhov txawv hom kev lag luam Yuav ua li cas txog silicone thiab ntxiv silicone?
1. Nws tuaj yeem txawv ntawm daim ntawv thov:
Kev lag luam silicon roj hmab feem ntau yog siv rau hauv cov khoom siv iav, pwm tsim kev lag luam, gypsum khoom plig kev lag luam, khoom ua si yas kev lag luam, khoom siv tes ua khoom plig, kev lag luam kho kom zoo nkauj, rooj tog kho kom zoo nkauj, kev lag luam kho vaj tse, kev lag luam khoom siv tes ua, kev lag luam khoom siv tes ua tsis zoo, tswm ciab paj ntaub, Gypsum duav kab, etc.; Ntxiv-hom silicone feem ntau yog siv rau hauv kev tsim cov ncuav mog qab zib qauv pwm, silicone gaskets, kev kho mob-qib thiab khoom noj khoom haus-qib kev kho mob hoses, haus dej kav, lub cev kua dej diversion hlab, cov neeg laus cov khoom, precision kev lag luam qauv ua, thiab lwm yam.
2. Qhov txawv ntawm qhov ua tau zoo thiab qhov chaw ntawm silicone roj hmab
Kev lag luam-hom silicone roj hmab tsis nruj raws li cov khoom siv silicone roj hmab ntxiv raws li kev siv thev naus laus zis thiab kev ua lub sijhawm vulcanization, yog li nws tsis tuaj yeem ncav cuag qhov kev ua tau zoo ntawm cov roj hmab silicone ntxiv rau qhov kub thiab txias (-50-250) , feem ntau nyob ib ncig ntawm 180 degrees, tom qab tshaj 180 degrees Kev ua haujlwm ntawm silicone roj hmab yuav cuam tshuam zoo heev; Qhov thib ob, vim tias nws yog catalyzed los ntawm organotin, cov khoom tsim tawm yuav muaj qhov tsis hnov tsw zoo thaum pib, thaum ntxiv-hom silicone roj hmab yog catalyzed los ntawm platinum thiab tsis muaj ntxhiab tsw (koj tuaj yeem siv tsis hnov tsw thaum txheeb xyuas txoj kev txheeb xyuas); Thib peb, muaj silicone roj hmab feem ntau yog dawb los yog translucent, thaum cov zaub mov-ntxiv silicone roj hmab tsis yog dawb, thiab feem ntau yog translucent thiab pob tshab. Nrog rau lub sijhawm dhau los, cov khoom lag luam ua los ntawm cov khoom siv silicone roj hmab yuav oxidized thiab yellowed los yog cov kab tsaus yog tias cov khoom tsis zoo, thaum ntxiv hom silicone roj hmab kuj ruaj khov thiab yuav tsis tshwm sim hauv qhov xwm txheej no.
Yuav ua li cas txiav txim seb cov khoom ntawm cov khoom siv silicone tau mus txog qib zaub mov?
Nrog rau kev nkag siab ntawm pej xeem kev paub txog cov khoom siv silicone, cov khoom siv silicone kuj nyiam los ntawm cov neeg siv khoom feem ntau. Thaum xaiv ntau yam khoom siv hauv tsev, cov khoom siv silicone yuav tsum tau muab qhov tseem ceeb, xws li cov pacifiers me nyuam, hnab ris, thiab lwm yam. nyob rau hauv ib qho xwm txheej, cov khoom siv silicone yuav tsum yog cov khoom noj khoom haus silicone, thiaj li xyuas kom meej tias lawv yuav tsis ua rau muaj kev phom sij. cuam tshuam rau tib neeg lub cev thaum siv cov neeg siv khoom. Yog li, yog tias koj xav kho cov khoom siv silicone, yuav ua li cas txiav txim siab seb cov khoom ntawm cov khoom siv silicone tau mus txog qib zaub mov?
Cov khoom noj khoom haus qib silicone tsis muaj tshuaj lom thiab tsis muaj ntxhiab, nrog lub siab transparency, ruaj khov tshuaj, softness, zoo elasticity, txias tsis kam, kub tsis kam, muaj zog nqus dej, tsis muaj tshuaj lom thiab phiv rau tib neeg lub cev, thiab cov tshauv hlawv. yog dawb. Cov khoom siv silicone roj hmab zoo tib yam siv cov roj hmab silicone zoo tib yam, uas muaj qhov tsis hnov tsw, thiab yuav tig daj lossis tsaus ntuj nrog lub sijhawm, thiab cov tshauv hlawv yog xim dub.
Raws li cov kev cai ntawm US FDA, cov khoom siv roj hmab silicone uas tuaj yeem tiv nrog cov zaub mov yuav tsum ua raws li peb yam hauv qab no:
1. Nws yuav tsis tso cov khoom uas ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv. Qhov no yuav tsum tau hais tias cov khoom nws tus kheej yuav tsis muaj tshuaj lom, thiab cov khoom yuav tsum muaj cov tshuaj ruaj khov txaus thiab yuav tsis corroded los ntawm ntuj oxidation.
2. Nws tsis tuaj yeem ua rau tsis tuaj yeem hloov pauv hauv cov khoom noj muaj pes tsawg leeg. Cov khoom tsis tuaj yeem hnov mob chemically nrog cov khoom nws kov, thiab cov khoom muaj pes tsawg leeg tsis tuaj yeem hloov pauv vim yog kev sib cuag nrog cov khoom noj.
3. Cov khoom noj khoom haus tuaj yeem txo qis (hloov saj, tsw, xim, thiab lwm yam ntawm cov khoom noj).
Tau kawg, cov qauv xeem ntawm ntau lub teb chaws hauv ntiaj teb no txawv me ntsis. Piv txwv li, tus qauv German LFGB yuav tsum muaj cov kev ntsuam xyuas hauv qab no rau cov khoom siv roj hmab silicone: ① 3 cov kev xeem tsiv teb tsaws chaw; ② (VOC) organic volatile teeb meem cov ntsiab lus; ③ kuaj tus nqi peroxide; ④ organotin compounds Test; ⑤ Kev ntsuas ntsuas.
