Txhawm rau txiav txim siab seb silicone muaj cov tshuaj phem, koj tuaj yeem ua nws los ntawm cov hauv qab no:
1. Kev soj ntsuam thiab kuaj
Kev tshuaj xyuas qhov tshwm sim:
Saib xyuas seb cov xim ntawm cov khoom siv silicone zoo li cas, seb lub ntsej muag yog du, thiab seb puas muaj flash, burrs, thiab lwm yam.
Cov khoom zoo silicone feem ntau yog translucent lossis pob tshab, nrog cov xim dawb me ntsis.
Kev ntsuas kub:
Ntuj silicone yuav tsim cov ntxhiab tsw tsw zoo ib yam li cov plaub hau hlawv thaum hlawv, vim tias silicone yuav decompose rau hauv silica thiab dej vapor thaum hlawv.
Yog tias muaj ntxhiab tsw ntxhiab lossis tsw ntxhiab thaum hlawv, nws yuav ua tsis tau zoo silicone nrog cov khoom tsis zoo ntxiv.
2. Kev kuaj xyuas lub cev
Elasticity thiab resilience:
Cov khoom siv silicone zoo muaj qhov zoo elasticity thiab resilience. Lawv yuav deform tab sis tsis tawg thaum rub nyuaj, thiab yuav sai sai rov qab mus rau lawv cov qub qub tom qab tso tawm.
Inferior silicone tej zaum yuav tsis zoo elasticity thiab tsis muaj zog resilience vim qhov sib ntxiv ntawm cov muab tub lim ntau dhau.
Hardness thiab tensile zog:
Ntsuam xyuas qhov hardness thiab tensile lub zog ntawm silicone kom paub meej tias nws ua tau raws li cov khoom specification.
3. Tshuaj ntsuam xyuas muaj pes tsawg leeg
Heavy hlau ntes:
Siv cov cuab yeej tshaj lij los xyuas seb cov silica gel muaj cov hlau hnyav (xws li txhuas, cadmium, mercury, thiab lwm yam). Thaum cov hlau hnyav no sib sau ua ke rau qee yam hauv tib neeg lub cev, lawv yuav ua rau muaj kev puas tsuaj rau lub paj hlwb, lub plab zom mov, cov ntshav, thiab lwm yam.
Kev kuaj xyuas cov organic tebchaw (VOCs):
Tshawb xyuas seb cov silica gel puas muaj cov organic sib txuas, uas yuav ua rau muaj kev phom sij rau tib neeg kev noj qab haus huv.
Plasticizer thiab residual monomer nrhiav kom tau:
Plasticizers (xws li phthalates) yuav raug qhia ua cov khoom ntxiv thaum lub sij hawm tsim cov silica gel, uas yuav ua rau muaj kev phom sij rau tib neeg lub cev xeeb tub.
Residual monomers kuj yuav muaj kev cuam tshuam rau tib neeg kev noj qab haus huv.
4. Kev kuaj xyuas cov kab mob microbial thiab kev tshuaj ntsuam toxicological
Kev kuaj xyuas microbial:
Rau cov khoom noj khoom haus sib cuag nrog cov khoom siv roj hmab silicone, nws yog ib qho tsim nyog los kuaj xyuas cov kab mob sib kis, pwm thiab lwm yam kab mob ntawm qhov chaw thiab sab hauv.
Kev ntsuam xyuas toxicological:
Los ntawm kev sim tsiaj los yog kev sim hauv vitro, ntsuas qhov ua rau muaj kev phom sij ntawm silica gel thiab nws cov khoom rho tawm rau tib neeg kev noj qab haus huv.
5. Kev kuaj xyuas lub koom haum
Txhawm rau kom ntseeg tau qhov tseeb thiab kev ntseeg siab ntawm qhov kev xeem, nws raug nquahu kom xa cov qauv silica gel mus rau ib lub koom haum kuaj kev tshaj lij nrog cov kev tsim nyog thiab kev paub dhau los rau kev sim ntsuas. Cov tsev kawm ntawv no feem ntau yog nruab nrog cov cuab yeej ntsuas qib siab thiab cov neeg ua haujlwm kuaj, thiab tuaj yeem txiav txim siab seb cov silica gel puas muaj cov tshuaj phem.
Hauv cov ntsiab lus, kev txiav txim siab seb cov roj hmab silicone muaj cov khoom puas tsuaj yuav tsum tau ua tib zoo xav txog ntau yam, suav nrog kev tshuaj xyuas zoo li, kev kuaj lub cev, tshuaj lom neeg muaj pes tsawg leeg, kuaj microbial thiab tshuaj ntsuam toxicological. Nyob rau tib lub sijhawm, txhawm rau txhawm rau ua kom qhov tseeb thiab kev ntseeg siab ntawm qhov kev xeem, nws raug nquahu kom nrhiav kev pab los ntawm cov koom haum tshaj lij.
