Sib txawv silicone hardnesses muaj ntau daim ntawv thov sib txawv
0 Ntug A thiab 0 Ntug 30C hardness.Hom silicone no yog mos heev thiab muaj Q-elasticity zoo.Nws yog feem ntau siv los ua cov khoom tiav uas simulate qee qhov ntawm tib neeg lub cev, xws li lub hauv siab pads, lub xub pwg pluaj, insoles, thiab lwm yam.
5 ~ 10 hardness.Nws yog tsim rau sau thiab flipping khoom qauv nrog zoo heev qauv thiab yooj yim demoulding, xws li zus tau tej cov silicone pwm rau soaps thiab tswm ciab.
20 degree hardness.Nws yog tsim los ua cov khoom siv me me.Nws muaj viscosity tsawg, zoo fluidity, ua haujlwm yooj yim, yooj yim tso npuas, zoo tensile thiab tsim kua muag lub zog, thiab yooj yim pouring.
40 degree hardness.Rau cov khoom loj, nws muaj viscosity tsawg, zoo fluidity, ua haujlwm yooj yim, yooj yim tso npuas, zoo tensile thiab tsim kua muag lub zog, thiab yooj yim sau.
Yog tias koj siv cov txheej txheem ntau txheej txhuam pwm, koj tuaj yeem xaiv cov silicone hardness, xws li 30A lossis 35A, uas yooj yim rau kev khiav lag luam thiab tsis yooj yim rau deform.
Nta
Cov roj hmab series muaj cov kua Part B puag thiab Part A accelerator, uas tom qab sib tov ntawm qhov sib piv ntawm qhov hnyav, kho ntawm chav tsev kub kom hloov tau, siab tsim kua muag lub zog, RTV (chav kub vulcanizing) silicone rubbers.Lawv zoo tagnrho rau pwm qhov twg. Kev tso tawm yooj yim lossis kub ua haujlwm yog xav tau.Lawv tau pom zoo rau polyurethane, polyester, epoxy resins, thiab siv quav ciab.
Silicone roj hmab feem ntau yog siv rau casting kua yas resins, xws li polyurethane, epoxy los yog polyester vim hais tias cov resins los yog barrier coats siv nrog lawv tsis yuav tsum tau tso tawm tus neeg sawv cev.Yog li, cov khoom yas los ntawm silicone pwm feem ntau yog npaj txhij rau kev ua tiav yam tsis muaj kev ntxuav tawm lossis qhov tsis zoo ntawm qhov chaw vim yog tso tawm cov neeg ua haujlwm.
Silicone pwm kuj tuaj yeem tiv taus qhov kub siab (+ 250 ° F) ntawm qee cov polyester lossis acrylic resins lossis cov hlau melting tsawg zoo dua li lwm cov roj hmab.
