Yuav siv cov ntaub qhwv ua kom zoo li cas
1. Kev siv qhov tseeb: Thaum siv silicone log, thov siv txoj kev tom qab dov rov qab. (Tshwj xeeb tshaj yog ntxuav cov khoom tsis sib xws, xws li PCB pawg)
2. Kev Tu Silicone: Thov so nrog qhuav cawv, los yog qhuav nrog cua phom.
3. Tsis txhob kov cov tshuaj benzene thiab ester solvents (xws li dej Tianna, dej ntxuav dej, zaj duab xis dej, ethyl acetate, thiab lwm yam) thaum siv. Ib zaug hu rau, tam sim ntawd so nrog dej cawv qhuav thiab tshuab kom qhuav nrog cua phom.
4. Rau txhua lub sijhawm 5,000 zaus ntawm kev siv, yog tias qhov viscosity poob qis, thov nco ntsoov tias qhov tshwm sim no tshwm sim los ntawm cov roj hmab log sib kis tau. Ua raws li kev kho mob hauv qab no, ntxuav nws nrog dej cawv kom tsis txhob nyob rau hauv lub sijhawm, muab tso rau hauv qhov cub, thiab qhuav ntawm 50 ° C. Ci rau 30 feeb thiab lub viscosity sawv. Siv tus qauv no. Kev pab cuam lub neej ntawm peb lub log silicone yog ntau dua 60,000 zaug. Yog tias cov xwm txheej tsis muaj, ntxuav lawv nrog haus cawv, qhwv lawv hauv ntim ntim huv, thiab tso lawv rau 48 teev. Kuj tau muaj kev nce viscosity.
Teeb meem xav tau kev saib xyuas:
1. Nws raug txwv tsis pub siv cov tshuaj benzene thiab ester (xws li dej Tianna, dej ntxuav dej, zaj duab xis dej, ethyl acetate, thiab lwm yam) txhawm rau ntxuav cov silicone. Cov kuab tshuaj no yuav ua rau lub ntsej muag silicone, hnub nyoog, deform, thiab txo viscosity sai. qhov tshwm sim.
2. Thov tsis txhob siv lub log silicone los ntxuav cov hauv pem teb, phab ntsa, thiab pob zeb nchav: nws yog qhov yooj yim rau kos cov silicone.
3. Thov tsis txhob txhuam cov silicone nrog lub ntsej muag ntse.
3. Kev tu thiab cia:
Tom qab siv: Thov siv lub log log kom dov thiab ua dua ntawm daim ntawv nplaum ob peb zaug kom cov silicone silicone huv si.
Cia: Thov khaws cia ntawm benzene cov kuab tshuaj, inks thiab cov tshuaj tua kab mob, thiab muab tso rau hauv lub ntim huv.
Thaum tsis siv: Txav deb rau thaj chaw muaj peev xwm kub thiab lub hnub ncaj qha.
