Yuav ua li cas thiaj ua rau kev tshuaj ntsuam luam ntawv silicone pob tshab?
Nov yog qee txoj hauv kev los ua kev tshuaj ntsuam luam ntawv silicone pob tshab:
Kev xaiv raw khoom
Xaiv cov khoom zoo hauv qab polymers:
Xaiv cov pob tshab silicone puag polymer cov ntaub ntawv raw yog qhov tseem ceeb. Cov ntaub ntawv zoo polysiloxane lawv tus kheej muaj cov khoom siv kho qhov muag zoo dua, cov qauv molecular tsis tu ncua, thiab cov ntsiab lus tsis zoo, uas tuaj yeem lav qhov pom tseeb ntawm cov khoom siv silicone tiav. Piv txwv li, qee lub npe nrov tau tsim thiab tsim cov roj hmab silicone tshwj xeeb rau cov khoom lag luam siab, uas ua tau zoo dua nyob rau hauv cov nqe lus ntawm lub teeb transmittance.
Ua kom haum additives:
Catalysts:Xaiv cov catalysts uas yuav tsis muaj kev cuam tshuam tsis zoo rau cov pob tshab, xws li platinum catalysts, uas muaj cov catalytic siab thiab yuav tsis qhia cov xim impurities thaum cov txheej txheem tshuaj tiv thaiv, uas yuav pab tshuaj ntsuam luam ntawv silicone kom muaj kev pom zoo tom qab kho.
Plasticizers:Siv cov xim tsis muaj xim, pob tshab, thiab cov khoom siv sib xws, xws li qee qhov hnyav-hnyav silicone roj plasticizers, uas tuaj yeem txhim kho qhov yooj yim ntawm silicone thiab yuav tsis ua rau silicone turbid, uas yog qhov zoo rau kev txhim kho pob tshab tag nrho.
Cov txheej txheem ntau lawm
Precisely tswj cov txheej txheem stirring:
stirring ceev thiab sij hawm: Thaum stirring thiab sib tov ntau yam khoom ntawm silicone, stirring ceev thiab sij hawm yuav tsum tau tswj kom tsim nyog. Kev nrawm nrawm thiab lub sijhawm ntev dhau lawm yuav yooj yim ua rau huab cua ntau dhau los ua npuas, uas yuav ua rau cov khoom siv silicone zoo li opaque thiab pos huab. Nws yog feem ntau pom zoo kom siv nruab nrab qis-ceev stirring, thiab lub sij hawm yuav tsum tau tswj kom cov khoom xyaw tag nrho thiab sib npaug. Piv txwv li, do ntawm qhov ceev ntawm 30-50 revolutions ib feeb li ntawm 5-10 feeb (nyob ntawm seb tus qauv thiab tus nqi).
Kev kho degassing: Tom qab nplawm, nco ntsoov ua haujlwm zoo degassing. Koj tuaj yeem siv lub tshuab nqus tsev degassing los muab cov silicone tso rau hauv lub tshuab nqus tsev thiab khaws cia ntawm lub tshuab nqus tsev tsim nyog (feem ntau yog li ntawm - 0.08 txog - 0.1MPa) rau ib lub sijhawm (xws li {{4} }} feeb) kom tso cai rau cov pa npuas sib xyaw kom tso tawm tag nrho, ua rau cov khoom siv silicone zoo sib xws thiab pob tshab.
nruj me ntsis tswj cov kev kho mob:
Kev tswj qhov kub thiab txias:Ua haujlwm raws li qhov ntsuas kub kub tau pom zoo hauv cov khoom siv silicone, feem ntau kho ntawm chav tsev kub lossis cua sov kom tsim nyog (xws li 60-100 degree , nyob ntawm cov khoom). Qhov kub thiab txias dhau lawm yuav ua rau muaj kev hloov pauv hauv cov qauv hauv cov silicone, ua rau cov xim daj hauv zos thiab lwm yam teeb meem, thiab cuam tshuam rau pob tshab; Qhov kub qis dhau yuav ua rau kev kho tsis tiav thiab tsis pom qhov pom tseeb.
Humidity tswj:Nws tseem yog ib qho tseem ceeb kom cov av noo ntawm curing ib puag ncig qis. Yog tias cov av noo siab dhau lawm, cov dej noo tuaj yeem koom nrog hauv kev kho cov tshuaj tiv thaiv los yog condense ntawm lub silicone kom tsim pos huab thiab txo cov pob tshab. Cov av noo zoo tshaj plaws ntawm kev kho ib puag ncig yuav tsum tau tswj nyob ib puag ncig 40%-60%.
