Teb: Vim hais tias lub hauv paus cov ntaub ntawv ntawm cov kua ntxiv silicone yog vinyl triethoxysilane ua cov khoom tseem ceeb, thiab nws tus neeg sawv cev kho yog platinum catalyst.Vim tias platinum yog cov khoom siv hlau hnyav thiab yog qhov muag heev, nws ntshai tshaj plaws ntawm cov tshuaj tin, yog li cov hlau xws li hlau tuaj yeem ua rau tsis muaj zog.Yog tias nws tsis kho, qhov saum npoo yuav nplaum, uas yog hu ua lom lossis tsis tiav kev kho.
Teb: Vim hais tias tus neeg sawv cev curing ntawm condensation hom chav tsev kub pwm silicone yog ua los ntawm ethyl orthosilicate, yog hais tias lub platinum catalyst curing agent reacts nrog peb silicone, nws yuav tsis kho.
Teb: Thaum cov khoom yuav tsum tau ua los ntawm ntau hom silicone, nco ntsoov tsis txhob siv cov khoom siv los ua condensation-type silicone los ua cov khoom siv silicone ntxiv.Yog tias cov khoom siv sib xyaw ua ke, kev kho tsis tuaj yeem tshwm sim.
Teb: Ua ntej, thaum ua pwm, peb yuav tsum xaiv silicone nrog hardness tsim nyog raws li qhov loj ntawm cov khoom.Qhov thib ob, cov roj silicone tsis tuaj yeem muab ntxiv rau hauv silicone, vim tias qhov ntau dua ntawm cov roj silicone ntxiv, cov pwm yuav ua softer thiab lub zog tensile yuav raug txo.thiab lub zog tsim kua muag yuav raug txo.Silicone ib txwm ua tsis tshua muaj zog thiab nws lub neej kev pab yuav raug txo.Nws raug nquahu kom cov neeg siv khoom tsis txhob ntxiv cov roj silicone.
Teb: Yog.Txawm li cas los xij, thaum txhuam cov pwm, lub thickness ntawm silicone yuav tsum zoo ib yam, vim hais tias yog nws tsis txhuam tusyees thiab tsis muaj fiberglass daim ntaub ntxiv, cov pwm yuav torn yooj yim.Qhov tseeb, fiberglass daim ntaub zoo li yog vim li cas hlau thiab kub ntxiv rau pob zeb.
Teb: Qhov kom zoo dua ntawm cov silica gel ntxiv yog tias nws tsis tso cov molecules tsawg thaum siv.Tsawg molecules suav nrog cov dej me me, cov kua qaub dawb, thiab qee cov cawv me me.Nws shrinkage yog qhov tsawg tshaj plaws thiab feem ntau tsis tshaj Ob txhiab.Qhov txiaj ntsig loj tshaj plaws ntawm kev sib ntxiv-hom silicone yog nws lub neej ua haujlwm ntev, thiab lub zog tensile thiab lub zog tsim kua muag yuav tsis txo qis lossis txo qis thaum khaws cia.Qhov zoo ntawm condensation silica gel: Condensation silica gel yog yooj yim rau kev khiav lag luam.Tsis zoo li ntxiv silica gel, uas yooj yim lom, nws tuaj yeem siv tau nyob rau hauv txhua yam mob.Lub zog tensile thiab lub zog tsim kua muag ntawm cov pwm ua nrog condensation silicone zoo dua thaum pib.Tom qab tso tseg rau ib lub sijhawm (peb lub hlis), nws lub zog tensile thiab lub zog tsim kua muag yuav txo qis, thiab qhov shrinkage tus nqi yuav ntau dua li ntawm cov silicone ntxiv.Tom qab ib xyoos, pwm tsis siv lawm.
Teb: Qhov kub ntawm cov pwm tsis tuaj yeem qis dua 150 degrees, thiab nyiam dua tsis tshaj 180 degrees.Yog tias qhov kub ntawm pwm qis dhau, lub sijhawm kho yuav ntev dua.Yog tias qhov kub thiab txias heev, cov khoom siv silicone yuav raug hlawv.
Teb: Cov khoom ua los ntawm additive molding roj hmab tuaj yeem tiv taus qhov kub ntawm 200 degrees mus rau rho tawm 60 degrees thiab tuaj yeem siv tau.
