Dab tsi yog qhov tseem ceeb ntawm kev txhaj tshuaj silicone?

Cov ntsiab lus tseem ceeb ntawm kev txhaj tshuaj ua kua silicone suav nrog cov hauv qab no:

1. Lub xeev lub xeev thiab tsos
Lub xeev lub cev:Ua kua, feem ntau yog nyob rau hauv daim ntawv ntawm ob-tiv (tivthaiv ib, tivthaiv B) ntim.
Zog:Cheebtsam A thiab B yog pob tshab thiab tsis muaj qhov tsis txaus ntseeg. Tom qab sib tov, lawv yuav tshwm sim translucent lossis hauv cov xim tshwj xeeb (kho raws li cov neeg siv khoom xav tau).
2. Viscosity thiab fluidity
Viscosity:Lub viscosity ntawm Cheebtsam A thiab B ua ntej sib xyaw yog feem ntau, thiab lub viscosity tom qab ua kua silicone tuaj yeem ntws los cuam tshuam thiab sau cov pwm thaum lub cev sib txhuam. Cov nqi tshwj xeeb ntawm viscosity yuav sib txawv nyob ntawm cov qauv khoom thiab cov neeg siv khoom xav tau.
Fosure:Silicone kua muaj cov kua zoo thiab tuaj yeem nkag mus rau cov pwm zoo ntawm cov pwm kom ntseeg tau tias muaj kev ncaj ncees thiab precision ntawm cov khoom.
3. Kev sib xyaw sib piv thiab lub sijhawm ua haujlwm
Sib tov sib piv:Cheebtsam A thiab B yog feem ntau sib xyaw hauv qhov sib piv ntawm 1: 1 kom ntseeg tau qhov kev ua tau zoo tshaj plaws ntawm cov khoom.
Lub sijhawm ua haujlwm:Cov sib xyaw ua kua silicone muaj qee lub sijhawm ua haujlwm, uas tuaj yeem khaws cia ntawm chav sov rau ntau tshaj 1 teev. Lub sijhawm tshwj xeeb nyob ntawm cov khoom qauv thiab kev ua kom vulcanization.
4. Vulcanization tej yam thiab hardness
Vulcanization tej yam kev mob:Lub pulcanization kub ntawm cov kua silicone yog feem ntau nyob rau hauv thaj tsam 80 {} {1} qib vulcanization yuav nyob nruab nrab ntawm 139 degree {3}} degree. Lub sijhawm ua kom tsis muaj zog sib txawv raws li cov tuab thiab cov duab ntawm cov khoom lag luam, feem ntau nruab nrab ntawm ob peb feeb thiab ntau dua kaum feeb.
Hardness:Lub hardness ntawm cov kua silicone muaj peev xwm tswj tau los ntawm kev kho cov mis thiab vulcanization tej yam kev mob, feem ntau ntawm 20 thiab 70 degrees ntug dej nyuaj.
5. Cov Khoom Siv Neeg Kho Tshuab
Lub zog tensile:Silicone kua muaj lub zog siab tensile lub zog thiab tuaj yeem tiv taus qee qhov kev quab yuam sab nraud yam tsis muaj tawg.
Ntuag lub zog:Kua muag lub zog tseem yog ib qho ntawm cov kws ua kua tseem ceeb ntawm cov kua Silicone, uas txiav txim siab cov tshuaj tiv thaiv ntawm cov khoom thaum raug rhuav tshem.
6. Thermal stability thiab huab cua tsis kam
Thermal Stability:Silicone kua muaj cov khoom siv ua kom zoo thiab muaj peev xwm tswj tau ruaj khov ua tau zoo ntawm qhov kub uas tsis muaj ntshav lossis laus.
Huab cua Kuj:Silicone kua kuj muaj huab cua zoo tiv thaiv, tuaj yeem tiv thaiv cov yaig ntawm ib puag ncig xws li ultraviolet rays thiab ozone, thiab tswj cov khoom lag luam tshiab ntawm cov khoom.
7. Lwm yam tsis muaj
Ntawj ntom:Qhov ceev ntawm cov kua silicone kua feem ntau yog nruab nrab ntawm 1. {}}}}} ~ 1.2g / thiab tus nqi tshwj xeeb nyob ntawm cov qauv khoom thiab cov qauv mis.
Lineear Shrinkage:Silicone kua yuav txiav rau qee yam thaum lub sij hawm vulcanization, thiab kab shrinkage feem ntau yog ib puag ncig 2%.

Hauv cov ntsiab lus, cov ntsiab lus tseem ceeb ntawm kev txhaj tshuaj ua kua roj xws li lub xeev thiab lub sijhawm ua haujlwm, cov khoom siv hluav taws xob, thiab lwm yam kev sib xyaw ua ke xws li ntom thiab linear shrinkage. Cov kev tsis ua haujlwm no txiav txim siab txog kev ua tau zoo thiab kev ua tiav ntawm kev txhaj tshuaj silicone.
