LSR 1: 1 silicone pwm ua kev qhia ua haujlwm
1. Cov qauv tu thiab kho
2. Ua ib lub thav duab ruaj khov rau tus qauv thiab sau qhov sib txawv nrog kub yaj kua nplaum phom
3. Txhaj tshuaj molding tus neeg sawv cev rau tus qauv kom tsis txhob muaj adhesion
4. Sib tov tag nrho thiab nplawm cov A thiab B raws li qhov hnyav piv ntawm 1: 1 (do hauv ib qho kev taw qhia kom tsis txhob nkag mus rau huab cua ntau dhau)
5. Muab cov silicone sib xyaw rau hauv lub tshuab nqus tsev thiab tso tawm cua
6. Ncuav cov silicone rau hauv lub thawv ruaj
7. Tom qab 8 teev ntawm kev tos, lub solidification tiav, ces tshem tawm cov qauv
Cov yam ntxwv ntawm LSR silicone
1.LSR silicone yog AB dual pawg faib, sib xyaw thiab nplawm tusyees A thiab B los ntawm qhov hnyav piv ntawm 1: 1, .
Lub sijhawm ua haujlwm yog ~ 30 feeb, lub sijhawm kho yog ~ 2 teev, thiab de-pwm hauv 8 teev.
2. Lub hardness muab faib ua: super mos silicone -hauv qab 0A, 0A-60A pwm silicone,
muaj qhov zoo ntawm cov xim ntev ntev thiab zoo elasticity3.Nyob rau hauv ib txwm kub, lub viscosity ntawm LSR silicone yog hais txog 10,000, uas yog ntau sparse tshaj cov condensation pwm silicone,
yog li nws tuaj yeem siv los ua kev txhaj tshuaj molding raw khoom
4. LSR silicone tseem hu ua platinum curing silicone.Cov khoom siv silicone no siv platinum ua cov khoom siv hauv cov tshuaj tiv thaiv polymerization.Yuav tsis muaj cov khoom decomposition.
nrog ze li ntawm tsis muaj ntxhiab tsw, LSR silicone yog dav siv los ua pwm zaub mov thiab cov neeg laus.Nws yog cov khoom siv silicone zoo tshaj plaws.
5. LSR silicone yog cov kua pob tshab, tuaj yeem siv cov xim zoo nkauj rau cov xim zoo nkauj.
6. LSR silicone tuaj yeem kho tau los ntawm chav tsev kub, kuj tuaj yeem ua kom sov thiab nrawm.
Qhov ntsuas kub cia tuaj yeem mus los ntawm qis -60 ° C mus txog qhov kub siab ntawm 350 ° C, uas tsis cuam tshuam rau cov ntsiab lus ntawm cov zaub mov-qib ib puag ncig silicone.
Dab tsi yog tus curing tus neeg sawv cev rau ntxiv silicone roj hmab?
Tus neeg sawv cev kho ntawm ntxiv silicone roj hmab yog platinum catalyst
Ntxiv silicone roj hmab feem ntau kho los ntawm platinum catalysts, xws li zaub mov qib silicone, txhaj molding silicone, thiab lwm yam.
Ob lub ntsiab lus ntxiv silicone roj hmab yog tsim los ntawm vinyl polydimethylsiloxane thiab hydrogen polydimethylsiloxane.Nyob rau hauv catalysis ntawm platinum catalyst, ib tug hydrosilylation cov tshuaj tiv thaiv tshwm sim, thiab tus ntoo khaub lig-txuas network yog tsim.lub cev elastic
