Dab tsi yog cov xwm txheej cuam tshuam rau cov yam ntxwv ntawm silicone khob hau?

Viscosity: Cov tshuaj tiv thaiv kev ntws tawm cov yam ntxwv ntawm cov kua, pseudo-kua lossis pseudo-cov khoom siv, uas yog, kev sib txhuam sab hauv lossis sab hauv ntws tsis kam ntawm cov qauv molecules thaum nws ntws nyob rau hauv qhov kev txiav txim ntawm sab nraud quab yuam. Nyob rau hauv ib txwm muaj tshwm sim, viscosity yog ncaj qha sib luag mus rau lub hardness.

Hardness: Muaj peev xwm ntawm cov khoom siv ib cheeb tsam tiv thaiv cov khoom tawv uas nias rau hauv nws cov nplaim yog hu ua hardness. Cov roj hmab Silicone muaj qhov Shore hardness ntau txog 10 txog 80, uas muab cov tsim qauv muaj kev ywj pheej tag nrho los xaiv qhov xav tau qhov nyuaj txhawm rau ua kom tiav qhov haujlwm tshwj xeeb. Ntau cov txiaj ntsig hauv nruab nrab cov tawv tawv tuaj yeem ua tiav los ntawm kev sib xyaw nrog cov polymer substrates, cov tshuaj ntsaws thiab cov khoom sib ntxiv hauv cov khoom sib txawv. Zoo sib xws, lub sijhawm thiab kev ntsuas kub ntawm kev ua kom sov thiab kho kom zoo kuj tuaj yeem hloov qhov tawv tawv yam uas tsis rhuav tshem lwm cov yam ntxwv ntawm lub cev.

Lub zog Tensile: Lub zog Tensile txhais tau hais tias lub zog uas xav tau rau txhua chav ua haujlwm ua rau ib qho khoom ntawm cov khoom siv roj hmab los rhuav. Lub zog tensile ntawm thermally vulcanized khoom silicone roj hmab yog nruab nrab ntawm 4.0-12.5MPa. Lub zog tensile ntawm fluorosilicone roj hmab yog nruab nrab ntawm 8.7-12.1MPa. Lub zog tensile ntawm kua roj hmab silicone yog nyob rau hauv thaj tsam ntawm 3.6-11.0MPa.

Cov kua muag dag zog: Qhov ua tsis kam rau qhov nthuav ntawm kev txiav lossis thais thaum sib zog siv rau cov qauv txiav. Txawm hais tias nws muab tso rau hauv qab qhov kev txhawj xeeb siab kawg tom qab txiav, cov ntaub npog lub cev muaj peev xwm tso cov roj hmab silicone tsis tuaj yeem nrawm. Lub zog kua muag ntau ntawm kub-vulcanized khoom silicone roj hmab yog nruab nrab ntawm 9-55 kN / m. Lub zog kua muag ntau ntawm fluorosilicone roj hmab yog nruab nrab ntawm 17.5-46.4 kN / m. Lub zog tsim kua muag ntawm cov kua roj hmab kua roj hmab muaj txog 11.5-52 kN / m.

Elongation: Feem ntau hais txog" Qhov kawg Txhaum Elongation" lossis qhov feem pua ​​nce piv rau qhov ntev ntev thaum cov qauv tawg. Thermally vulcanized solid silicone rubber feem ntau muaj elongation nyob rau hauv thaj tsam ntawm 90 txog 1120%. Kev dav dav ntawm fluorosilicone roj hmab yog thaj tsam li 159 thiab 699%. Qhov dav dav dav ntawm cov kua roj kua roj silicone yog nruab nrab ntawm 220 thiab 900%. Kev ua cov txheej txheem sib txawv thiab kev xaiv ntawm cov hardener tuaj yeem hloov pauv nws cov elongation. Lub elongation ntawm silicone roj hmab muaj ntau qhov uas yuav tsum tau ua nrog kev ntsuas kub.

Lub sijhawm ua haujlwm 1: Lub sijhawm ua haujlwm tau muab suav los ntawm lub sijhawm thaum colloid ntxiv rau tus neeg saib xyuas vulcanizing. Muaj tiag tiag tsis muaj kev txwv tsis pub dhau lub sijhawm ua haujlwm no thiab lub sijhawm tom qab lub sijhawm vulcanization. Lub colloid tau dhau los lawm vulcanization los ntawm lub sijhawm tus neeg sawv cev vulcanizing ntxiv. Lub sijhawm ua haujlwm no txhais tau hais tias 30 feeb ntawm qhov tshwm sim vulcanization ntawm cov khoom tsis cuam tshuam rau qhov zoo ntawm cov khoom tiav. Yog li no, ntau lub sijhawm khaws cia rau hauv cov txheej txheem cov khoom lag luam, cov txiaj ntsig ntau nws yog rau cov khoom tiav.

Lub sijhawm Vulcanization: Qee qhov chaw yuav hais tias nws yog curing lub sijhawm. Hauv lwm lo lus, qhov tshwm sim ntawm vulcanization ntawm silica gel yog qhov tom qab tom qab ntawd ntev. Qhov no pib xaus, uas txhais tau hais tias cov khoom lag luam twb muaj lawm, tab sis qhov tseeb tseem muaj qee qhov me me ntawm cov tshuaj tiv thaiv uas tsis tau xaus. Yog li, cov khoom lag luam ua los ntawm cov roj hmab silicone, xws li silicone pwm pwm, feem ntau yuav siv sij hawm ua ntej siv.
