Lub hardness ntawm cov kua silicone yog li ntawm 0 degree A txog 100 degree A, nrog ib chav tsev ntawm txhua 5 degrees nyob rau nruab nrab. Cov kua silicone ntawm txhua qhov hardness muaj kev siv sib txawv. Ntawm no peb qhia txog cov khoom siv silicone, uas yog ib hom kua silicone. Feem ntau, lub hardness ntawm additive kua silicone yog muab faib ua high hardness, medium hardness, thiab soft hardness. Hauv qab no, peb yuav qhia txog kev siv silicone uas phim cov qib hardness sib txawv.
Ib. khoom ntiag tug
Elongation thiab tensile lub zog ntawm silicone:
Silicone mos mos heev (0 degree A): muaj qhov siab elongation thiab tsis muaj zog tensile, nrog lub zog tsim kua muag tsawg thiab siab elongation ntawm pwm silicone.
Mos silicone (5-10 degree A): Nruab nrab elongation thiab tensile zog, haum rau ntau yam kev siv.
Medium hardness silicone (20-30 degree A): nyuaj dua li mos silicone, tab sis kuj muaj qee qhov elasticity thiab compressibility.
Ib qho nyuaj silicone (40-50 degree A): Cov tawv nqaij nruab nrab, nrog qee qhov elasticity thiab compressibility.
Hard silicone (60-90 degree A): Nyuaj heev, nrog kev hnav zoo heev thiab kub ua haujlwm.
Ob. daim ntawv thov cheeb tsam
1. Cov silicone mos mos heev: haum rau cov ntaub ntawv uas yog mos, nkhaus, stretchable, los yog viav vias, xws li menyuam yaus cov khoom ua si, qauv, thiab lwm yam.
2. Mos silicone: haum rau ua cov mos mos gaskets, sealing gaskets, automotive qhov chaw, thiab lwm yam.
3. Medium hardness silicone: feem ntau siv rau cov khoom siv hluav taws xob, cov ntaub ntawv tiv thaiv, thiab lwm yam.
4. Silicone tawv me ntsis: tuaj yeem siv rau hauv tsheb ntsaws ruaj ruaj, pwm, tiv thaiv plam, thiab lwm yam.
5. Hard silicone: haum rau kev txhaj tshuaj pwm, ntau yam pob qij txha, sealing rings, hnav-resistant qhov chaw, thiab lwm yam.
6. Super hard silicone: feem ntau yog siv hauv teb xws li kub tsis kam, acid thiab alkali tsis kam, thiab hnav tsis kam.
Peb. Khoom nta
1. Squeezing zog: Tsawg hardness cov khoom yuav maj mam txo nyob rau hauv quab yuam, thaum siab hardness yuav nce.
2. Cov kua muag tsis kam: qhov siab dua qhov hardness, qhov tsis muaj zog ntawm cov khoom tsim kua muag, thiab qhov qis zog, qhov zoo dua cov kua muag kuj.
3. Tensile quab yuam: Nws muaj ib qho kev sib raug zoo nrog hardness thiab cuam tshuam cov deformation ntawm cov khoom.
4. Hnav tsis kam thiab qaug zog degree: Raws li qhov hardness nce, kev khiav mus ntev yuav cuam tshuam qhov txo qis ntawm qaug zog thiab qhov tshwm sim ntawm kev hnav tsis txaus.
5. Elasticity: Silicone nrog sib txawv hardness muaj qhov sib txawv elasticity, uas cuam tshuam rau kev ua tau zoo ntawm cov khoom siv.
Zuag qhia tag nrho, qib kev faib tawm, ntsuas txoj kev, thiab daim ntawv thov ntawm silicone hardness txawv. High hardness silicone nrog hardness ntawm {{0}} degree A yog haum rau fixture pwm thiab precision qhov chaw. Vim nws cov hardness siab, tsis muaj elasticity, thiab tsis kam mus rau deformation, nws muaj peev xwm txig replicate zoo qauv. Medium hardness silicone nrog 10-30 degree A yog dav siv hauv kev tsim cov pwm me me yooj yim, xws li xab npum, tswm ciab, thiab khoom noj pwm, nrog tsim kua muag zoo thiab rov siv dua. 0 degree Ib puag ncig tus phooj ywg zoo silicone yog tsim los ua kua nplaum DIY pwm thiab tib neeg lub cev qauv. Vim nws tsis tshua muaj hardness, zoo elasticity, thiab yooj yim foaming, nws muaj peev xwm replicate exquisite qauv. Qhov kev xaiv ntawm qhov sib txawv ntawm silicone hardness nyob ntawm qhov yuav tsum tau thiab kev siv scenarios ntawm cov pwm, kom ntseeg tau cov nyhuv ntawm cov pwm thiab zoo ntawm pwm. Peb xaiv cov khoom uas tsim nyog silicone hardness raws li cov kev xav tau tshwj xeeb txhawm rau ua kom tau raws li qhov xav tau ntawm ntau qhov chaw.
