Kev phom sij ntawm silica gel thiab silica hmoov thiab kev nyab xeeb ntawm peb cov khoom pom zoo FDA

Silica gel, raws li cov khoom siv, muaj ntau yam kev siv hauv ntau yam.Hauv kev tsim cov txheej txheem silicone, cov hmoov silicon qee zaum ntxiv los txhim kho qee yam khoom ntawm cov khoom.Txawm li cas los xij, silica gel hauv cov hmoov silicon kuj tuaj yeem ua rau muaj kev phom sij, uas kuj yog ib qho kev txhawj xeeb ntawm ntau tus neeg.Txawm li cas los xij, nws tsim nyog hais tias peb cov khoom siv silicone tau raug lees paub los ntawm FDA daim ntawv pov thawj qib zaub mov kom ntseeg tau tias muaj kev nyab xeeb ntawm cov khoom.

Ua ntej tshaj plaws, peb xav kom paub meej tias tsis yog txhua yam ntawm silica hmoov yog haum rau ntxiv rau silica gel.Qee cov hmoov silicon uas tsis kho yuav muaj impurities, uas yuav raug tso tawm thaum siv silicone, ua rau muaj kev hem thawj rau tib neeg kev noj qab haus huv.Txawm li cas los xij, hauv peb cov khoom, peb nruj me ntsis tshuaj ntsuam thiab tswj qhov chaw thiab zoo ntawm silicon hmoov los xyuas kom meej nws purity thiab kev nyab xeeb.

Qhov thib ob, qhov nyiaj ntawm silicon hmoov ntxiv kuj yog ib qho tseem ceeb uas xav tau kev saib xyuas.Qhov sib ntxiv ntawm cov hmoov silica ntau dhau tuaj yeem ua rau muaj kev hloov pauv hauv lub cev ntawm silica gel, xws li nce hardness thiab txo elasticity.Cov kev hloov pauv no tuaj yeem cuam tshuam rau kev ua haujlwm ntawm cov khoom lag luam thiab tseem tuaj yeem tso cov khoom tsis zoo thaum siv.Txawm li cas los xij, peb cov khoom lag luam silicone tau dhau los ua cov qauv tsim qauv thiab cov txheej txheem tsim khoom nruj kom ntseeg tau tias cov khoom siv silicon ntxiv nyob rau hauv qhov chaw nyab xeeb thiab yuav tsis ua rau muaj kev phom sij rau kev ua haujlwm ntawm cov khoom thiab tib neeg kev noj qab haus huv.

Txhawm rau suav nrog, txawm hais tias silica gel hauv cov hmoov silicon tuaj yeem ua rau muaj kev phom sij, tab sis dhau los ntawm kev tswj cov khoom siv nruj thiab kev tswj cov txheej txheem tsim khoom, cov kev phom sij no tuaj yeem zam tau.Peb cov khoom siv silicone tau dhau FDA daim ntawv pov thawj qib zaub mov, uas txhais tau hais tias peb cov khoom tau raug kuaj xyuas nruj thiab ntsuas raws li kev nyab xeeb, huv si thiab zoo, kom ntseeg tau tias cov neeg siv tuaj yeem tau txais cov khoom lag luam muaj kev nyab xeeb thiab txhim khu kev qha thaum siv.Yog li ntawd, xaiv peb cov khoom siv silicone, koj tuaj yeem so kom paub tseeb tias koj tsis tas yuav txhawj xeeb txog kev puas tsuaj los ntawm silica hmoov.
