Puas muaj cov kua silicone ua kom sov thiab khov?
Muaj silicone yog ib hom condensation silicone uas tuaj yeem kho tau ib txwm nyob hauv chav sov.Yog tias koj xav tau kev kho kom ceev ceev, koj tuaj yeem ua kom sov li ntawm 50 degrees.Tshaj 50 degrees Celsius yuav txo tau lub neej kev pab cuam ntawm cov pwm tiav.
Condensation silicone pwm ua cov kauj ruam ua haujlwm
1. Ntxuav cov pwm thiab kho nws
2. Ua ib lub thav duab ruaj khov rau cov pwm thiab sau qhov khoob nrog rab phom kub yaj kua nplaum
3. Txau tus neeg sawv cev tso rau ntawm pwm los tiv thaiv adhesion.
4. Sib tov cov silicone thiab curing agent kom huv si hauv qhov sib piv ntawm qhov hnyav ntawm 100: 2 thiab do tusyees (kwv rau hauv ib qho kev taw qhia kom tsis txhob muaj cua ntau dhau los ntawm kev nkag mus)
5. Muab cov silica gel sib xyaw rau hauv lub tshuab nqus tsev thiab tso pa tawm
6. Ncuav lub nqus tsev vacuumed silicone rau hauv lub thav duab ruaj
7. Tom qab tos 8 teev, tom qab kho tiav, demould thiab tshem tawm cov pwm.
Cov kev ceev faj
1. Lub sijhawm ua haujlwm ib txwm siv ntawm cov khoom siv silicone yog 30 feeb thiab lub sijhawm kho yog 2 teev.Nws tuaj yeem demoulded tom qab 8 teev thiab tsis tuaj yeem ua kom sov.
2. Qhov kev faib ua feem ntawm condensation silicone curing tus neeg sawv cev hauv qab 2% yuav ncua lub sij hawm kho, thiab qhov kev faib ua feem saum toj no 3% yuav ua kom qhov curing.
