Qhov nyuaj yog ib qho tseem ceeb ntawm qhov zoo ntawm silicone. Feem ntau hais lus, qhov siab dua cov roj hmab cov ntsiab lus, qhov qis dua qhov nyuaj. Qhov nyuaj ntawm silicone yog feem ntau raws li tus qauv Shore hardness, thiab lub tester kuj siv lub Shore hardness tester. Qhov nyuaj sib txawv ntawm 0 txog 100 degrees, nyob ntawm qhov ua haujlwm ntawm cov khoom siv. Cov khoom silicone muaj qhov nyuaj sib txawv raws li cov txheej txheem, thiab cov txheej txheem muaj ob hom kua-khoom.

 

Cov txheej txheem silicone kua siv tau los ua cov khoom siv roj hmab silicone "qib qis", xws li 0 txog 20 degrees, txawm tias koj tau txais nws ntawm tes, nws nplaum heev. Cov khoom silicone no feem ntau tsis tshua muaj, thiab kev tsim cov pwm silicone kua kim heev. Rau ob peb tug, nws feem ntau raug nqi kaum tawm txhiab daus las. Feem ntau cov txheej txheem kua yog ua tiav ntawm kwv yees li 10 txog 20 degrees. Rau qee cov khoom siv roj hmab silicone ua nrog cov thev naus laus zis kua, cov khoom silicone ua nrog cov thev naus laus zis kua tsis yooj yim tshem tawm tus kheej thiab tuaj yeem ua rau muaj teeb meem nrog cov npoo tsis du vim yog cov khoom siv. Yog li ntawd, cov txheej txheem kua yog qhov tsim nyog rau cov khoom silicone qis, uas tsis tas yuav tsum tau sib dhos nruj heev. Cov khoom silicone kua raug pom zoo: silicone pacifiers

 

2. Cov txheej txheem khov kho, tam sim no, qhov mos mos tsawg kawg nkaus ntawm cov txheej txheem silicone khov kho yog li 30 degrees, thiab qib siab tshaj plaws yog 80 degrees, txawm hais tias nws kuj tuaj yeem ncav cuag qib siab dua, tab sis tus nqi ua tsis tiav siab dhau, thiab cov khoom lag luam yog brittle heev thiab tsis yooj yim rau disassemble los ntawm lawv tus kheej. Yog li ntawd, qhov mos mos zoo tshaj plaws ntawm cov txheej txheem khov kho yog ntawm 30 degrees thiab 70 degrees. Cov khoom mos mos tsis tuaj yeem ua tau, tab sis ntug tshem tawm tus kheej zoo dua, thiab cov khoom muaj qhov zoo nkauj, tsis muaj burr.
