Dab tsi yog qhov ua rau cov khoom siv silicone ua meem
Tso lus
Nrog rau kev siv dav ntawm silicone khoom lag luam, muaj ntau yam khoom siv silicone uas yuav siv tau rau txhua qhov chaw ntawm lub neej. Txawm hais tias cov khoom siv silicone no tsis tsim nyog, lawv tuaj yeem ua lub luag haujlwm tseem ceeb, tab sis qee cov khoom siv silicone tau yooj yim los ua brittle thaum siv. Tom qab tau nkig, cov khoom siv silicone tsis tuaj yeem siv tsis tau lawm, yog li ntau tus neeg hnov mob taub hau. Tsis ntev los no, cov neeg muas zaub ntau tau sab laj cov khoom siv silicone kom ua tiav qhov nyuaj ntawm 70-80 degrees, yuav dhau los ua "nkig" heev, peb cov lus teb yog: tau.
Qhov tseeb, qhov laj thawj tseem ceeb rau lub brittleness ntawm silicone cov khoom lag luam yog qhov laj thawj tseem ceeb rau cov khoom siv silicone yog tias tom qab lub hardness ntawm cov khoom silicone nce mus txog 60 degrees lossis ntau dua, kua muag tsis kam thiab elasticity yuav plummet, uas ua rau cov khoom lag luam silicone ua. nkig heev! Yog tias koj xav tau cov khoom lag luam silicone ua qhov tsis khov, koj tuaj yeem nrhiav txoj hauv kev kom ua tiav qhov nyuaj hauv qab 60 degrees. Peb tuaj yeem ua tiav 20-80 degree hardness ntawm silicone khoom raws li tus neeg yuav tsum tau ua. Kom paub meej, thov hu rau cov neeg siv khoom lag luam. Tau kawg, qee qhov txheej txheem kev tsim kho tshuab tuaj yeem cuam tshuam qhov brittleness ntawm silica gel.
Hauv qab no yog qhov teeb meem ntau lawm, uas yuav muab rhaub rau qhov kub thiab txias thaum lub sij hawm ua cov txheej txheem ntau lawm ntawm cov khoom siv silicone, tab sis yog tias qhov ntsuas kub tsis txaus lossis lub sijhawm cua sov dhau lawm ntev, cov khoom lag luam silicone yuav ua nkig, ntxiv rau, Hauv kev siv thiab khaws cia, nws tsis tuaj yeem ua kom muaj qhov cua zoo, lossis qhov ntev ntawm theem nrab ntawm lub cev ntev dhau lawm, uas yuav ua rau qhov tshwm sim no. Qhov tseem ceeb tshaj plaws yog cov khoom teeb meem ntawm cov khoom siv silicone nws tus kheej. Yog tias cov khoom siv tsis zoo, nws tsis tuaj yeem hu. Lub zog tsim kua muag, yog li cov khoom lag luam silicone ua ntau yam tsis yooj yim.
Ntxiv rau cov no, lub brittleness ntawm silicone khoom kuj muaj feem xyuam nrog cov qauv tsim pwm. Yog tias cov qauv pwm tsis tsim nyog lossis cov qauv tsim tsis tsim nyog, nws tuaj yeem ua rau cov khoom siv silicone, uas yuav ua rau txhaws thaum lub sijhawm txheej txheem ntau lawm. Qhov tshwm sim no tshwm sim tiag tiag, thiab cov khoom lag luam silicone tsim tawm yuav ua rau nkig, yog li nws yuav tsum sim ua kom cov txheej txheem los yog pwm qauv ua ntej kev tsim thiab ua. Cov khoom uas pom zoo: silicone pwm
Qhov no yog ib qho ntawm cov laj thawj tseem ceeb ua rau lub brittleness ntawm silicone khoom. Tsis tas li ntawd, yog tias qhov ntsuas cua kub tsawg dhau los yog siv lub sijhawm siv sijhawm ntev dhau lawm, qhov tshwm sim kev laus yuav tshwm sim, uas tseem yuav ua rau cov khoom lag luam silicone ua nkig, yog li rau cov khoom lag luam silicone hais tias tom qab siv cov khoom rau ib lub sijhawm lub sijhawm, nws yuav tsum tau hloov rau lub sijhawm.
