Ntau lub sijhawm: Tsawg tsawg tshaj Crosslinking tom qab qhov kev pom zoo; Tshaj li no, tsis muaj kev txhim kho tseem ceeb tshwm sim.
Qho kawg: Kom lub sijhawm tsim nyog ua kom muaj kev tsim kho thiab ruaj khov av me me.
2. Kev tshem tawm ntawm cov zaub mov
Cov nyhuv ntawm lub sijhawm:Lub luv luv luv luv: Residual volatiles (piv txwv li, siv tau cov siloxannesed lossis kho cov khoom noj) nyob twj ywm, uas tuaj yeem ua rau:
Outgassing.
Txo kev coj dawb huv (tseem ceeb rau kev kho mob lossis khoom noj).
Cov tshuaj tsis zoo lossis ib puag ncig ruaj khov.
Optimized Dim: Tag nrho tshem tawm cov khoom tsis huv, txhim kho cov tshuaj lom neeg ua kom huv, huv, thiab thermal stability.
Ntau lub sijhawm: Tsis muaj txiaj ntsig ntxiv thaum tau tshem tawm ib zaug li; Cov cua sov txuas ntxiv tuaj yeem ua rau cov khoom siv tsis zoo.
Qho kawg: Ua kom lub sijhawm tsim nyog ua raws li cov kev cai tswj hwm thiab cov kev pheej hmoo tsis txaus.
3. Cov Khoom Siv Kho Tshuab
Cov nyhuv ntawm lub sijhawm:Lub luv luv luv luv:
Qhov muag qis dua, tensile lub zog, thiab elongation.
Cov kev hloov siab compression teeb tsa (rov qab los tsis zoo tom qab compression).
Optimized Dim: Kev tsim kho txhua yam, ntsuas elasticity, lub zog, thiab kev thev taus.
Ntau lub sijhawm: Kev kho mob dhau los tuaj yeem ua rau embrittlement lossis txo qis dua, tshwj xeeb tshaj yog thaum muaj kub.
Qho kawg: Lub sijhawm kom zoo rau cov neeg siv khoom siv.
4. Kev teeb tsa
Cov nyhuv ntawm lub sijhawm:
Lub luv luv luv luv: Cov kev teeb tsa siab dua, lub ntsiab lus ntawm cov ntaub ntawv khaws cia deformation tom qab lub sijhawm ntev compression.
Optimized Dim: Txo cov kev ntxhov siab ntau dua, txhim kho elasticity, thiab ua kom zoo dua los ntawm deformation.
Ntau lub sijhawm: Tsis muaj kev txhim kho tseem ceeb tom qab kev ua kom ntev.
Qho kawg: Lub sijhawm ua kom tiav kom zoo dua kev sib khi ua tau zoo hauv gaskets, O-rings, thiab lwm yam kev siv compression.
5. Thermal stability
Cov nyhuv ntawm lub sijhawm:Lub luv luv luv luv:
Thermal stability nyob tsis tiav, ua rau cov khoom siv tsis txaus ntawm cov sijhawm kub dhau sijhawm.
Optimized Dim: Txhim kho tshav kub tiv thaiv thiab ua kom cov khoom tiv thaiv tau pom ntev ntev kom muaj kev ntxhov siab yam tsis muaj kev nyab xeeb.
Ntau lub sijhawm: Lub sijhawm ntev tuaj yeem ua rau muaj oxidation silicone oxidation lossis kev tsis txheeb xyuas kev, txo lub neej.
Qho kawg: Ua kom muaj cov sijhawm ua kom tiav kev ua tau ntev ntev hauv qhov chaw kub.
6. Ua raws li cov qauv
Cov nyhuv ntawm lub sijhawm:
Lub luv luv luv luv: Ua tsis tau raws cov qauv (piv txwv li, FDA, USP chav VI, lossis tsheb) vim tias tsis tiav kev kho lossis muaj cov khoom tsis tiav.
Optimized Dim: Ua tau raws cov kev cai tswj kev cai rau kev kho mob, khoom noj khoom haus, lossis kev siv tsheb.
Ntau lub sijhawm: Tsis muaj txiaj ntsig ntxiv thaum ua raws li ua tiav tau tiav.
Qho kawg: Ua kom haum kom ua kom cov Silicone ntsib kev nyab xeeb thiab kev ua tau zoo.
Nrhiav Qhov Zoo Kawg
Qhov zoo tshaj plaws tom qab-rov qab los tu ncua nyob ntawm ntau yam:
Khoom Siv Khoom: Cov qhab nia LSR muaj qhov sib txawv ntawm cov cuab yeej tau zoo; Xa mus rau cov chaw tsim khoom siv cov tswv yim rau cov lus pom zoo.
Feem Thickness: Thicker qhov uas xav tau tu ncua kom ntseeg tau tias muaj kev sib tw kub thiab kev kho kom zoo.
Qho so: Kev kho dua tshiab ntxiv rau qhov kub thiab txias txo lub sijhawm uas yuav tsum tau ua, thaum txo qhov kub thiab txias tas sij hawm.
Daim Ntawv Thov Yuav Tsum Tau: Cov ntawv thov tseem ceeb (piv txwv li, kho mob, cov khoom noj-qib, yuav thov cov chaw txuas ntxiv kom ntseeg tau kev coj dawb huv thiab kev ua tau zoo.
Cov lus qhia dav dav rau cov neeg raug xaiv tom qab
| Qho so | Txog kawg | Daim ntawv thov |

| 250℃(482℃f) | 1-2 teev | Daim ntaub ntawv tseem ceeb (kev kho mob, cov khoom noj-qib) |
Cov ntsiab lus ntawm lub sijhawm ntev
| Txog kawg | Cuam tshuam rau cov khoom |
|---|---|
| Luv heev | Kev kho tus mob kho tsis tiav, qis dua lub zog, seem ntawm cov neeg hloov chaw, kev teeb tsa ntau compression. |
| Zoo rau | Siab tsim cov ntoo khaub lig, txhim kho mechanical tshuab, thermal, thiab tshuaj lom neeg. |
| Ntev dhau lawm | Muaj peev xwm cov ntaub ntawv tsis txaus ntseeg, embrittlement, txo kev txo qis (ntawm temps loj heev). |
Los ntawm kev thov qhov tseeb rov qab los kho lub sijhawm, koj tuaj yeem ua tiav cov khoom ua tiav tag nrho cov khoom siv ntawm cov neeg kho tshuab, kev ruaj khov, thiab ua raws li cov qauv kev lag luam.
