Tin Silicone Roj Hmab rau Resin Crafts Pwm Ua Cov Duab Duab

Tin Silicone Rubber rau Resin Crafts Moulds Ua

piav qhia luv luv:

Cov kauj ruam rau kev ua plaster crafts nrog kua pwm silicone yog raws li nram no:

Ntxuav tus tswv pwm thiab tshuaj tsuag ib txheej ntawm tus neeg sawv cev tso rau ntawm nws kom tiv thaiv nws los ntawm kev lo.
Siv lub tsev thaiv los puag ncig ib puag ncig pwm raws li qhov loj ntawm cov pwm.Feem ntau, nws yog li 1 mus rau 2 centimeters loj dua cov pwm.Rau lub teeb thiab cov pwm me me, cov kua nplaum yuav tsum tau siv los kho lawv kom tsis txhob muaj kev txaj muag ntawm tus tswv pwm floating tom qab sau cov kua nplaum.
Ntsuas tus nqi tsim nyog ntawm cov pwm ua kua silicone raws li qhov loj ntawm pwm, ntxiv tus neeg sawv cev kho kom raug, thiab tom qab ntawd do kom huv si.
Muab cov pwm sib xyaw ua kua silicone rau hauv cov pwm pwm, zoo dua npog qhov siab ntawm pwm los ntawm 1 mus rau 2 cm.
Tom qab sau cov kua nplaum, muab tso rau hauv qhov chaw ruaj khov thiab tos kom nws khov kho.
Tom qab lub plaster tau solidified, tshem lub tsev blocks thiab tshem tawm.

Nta ntawm condensation pwm silicone

1. Condensation silica gel muab faib ua ob ntu: silica gel thiab curing agent.Thaum lub sijhawm ua haujlwm, sib tov ob qho tib si raws li qhov hnyav piv ntawm silica gel thiab kho tus neeg sawv cev ntawm 100: 2 thiab do sib npaug.Lub sijhawm ua haujlwm yog 30 feeb thiab lub sijhawm kho yog 2 teev, nws tuaj yeem demoulded tom qab 8 teev thiab tuaj yeem kho tau ntawm chav sov yam tsis muaj cua sov.

2. Condensation silicone muab faib ua ob yam tshwj xeeb: translucent thiab milky dawb: cov pwm ua los ntawm translucent silicone yog smoother, thiab milky dawb pwm tuaj yeem tiv taus qhov kub siab tshaj 100 degrees Celsius.

3. Lub hardness ntawm condensation silica gel yog 10A / 15A / 20A / 25A / 30A / 35A, 40A / 45A yog milky dawb high-hard silica gel, thiab 50A / 55A yog super-hard silica gel, uas yog siv tshwj xeeb rau pwm tig ntawm tin, txhuas thiab lwm yam tsawg melting point hlau.

4. Lub cev kub viscosity ntawm condensation silica gel yog 20000-30000.Feem ntau, qhov siab dua qhov hardness, siab dua qhov viscosity.Nws kuj tuaj yeem kho tau.

5. Condensation silica gel kuj hu ua organotin kho silica gel.Thaum lub sijhawm ua haujlwm, vulcanization tshwm sim los ntawm organotin catalyst.Tus neeg sawv cev curing piv yog 2% -3%.

6. Condensation silica gel yog cov kua pob tshab los yog kua mis dawb.Pigments kuj tuaj yeem muab ntxiv los ua txhua yam xim.

7. Condensation silica gel tsis yooj yim rau cov tshuaj lom neeg, thiab cov pwm tsim tuaj yeem siv los ua cov khoom xws li gypsum, paraffin, epoxy resin, unsaturated resin, polyurethane AB resin, cement pob zeb, thiab lwm yam.
