Khoom Description
Thaum tshav kub kub hloov luam ntawv (rov qab) yog ib txoj hauv kev nrov los ua cov ntawv sau ntawm cov tsoos tsho.Muaj ntau lub tshuab luam ntawv tau txaus siab rau kev luam ntawv kub kub (rov qab).Tam sim no kuv yuav qhia cov txheej txheem luam ntawv.
KAUJ RUAM 1: Base txheej
Silicone number case AS6212 sib tov xim muab tshuaj txhuam ntawm qhov sib piv li 10%-15% los ntawm qhov hnyav (siv lub ntsuas hluav taws xob) thiab do zoo ces ntxiv catalyst AS-3(Lub caij nplooj zeeg thiab lub caij ntuj no siv) lossis AS{{4 }}(lub caij nplooj ntoos hlav thiab lub caij ntuj sov siv) ntawm qhov sib piv 10: 1 los ntawm qhov hnyav (siv lub ntsuas hluav taws xob), ntxiv qee cov silicone thinner P-2 raws li qhov xwm txheej tiag tiag.print ntawm PET tso zaj duab xis, luam tawm lub sijhawm nyob ntawm qhov tseeb Qhov xwm txheej, tom qab txhua qhov luam ntawv yuav tsum tau ua kom qhuav qhov chaw kom tsis txhob lo tom qab ntawd rov ua tib lub luam ntawv, CEEB TOOM: qhov kawg 2 zaug tsis tas yuav ci qhuav ntawm qhov chaw.
KAUJ RUAM 2: Sau nruab nrab txheej silicone AS6820NKB ua tus txuas txuas
Sib tov nruab nrab txheej silicone AS6820NKB nrog catalyst AS-A100 ntawm qhov sib piv 100: 5 los ntawm qhov hnyav (siv lub ntsuas hluav taws xob) thiab do zoo, luam tawm 3 zaug, txhua zaus yuav tsum tau ua kom qhuav saum npoo kom tsis txhob lo ces rov ua tib yam luam ntawv.
STEP 3: Luam kub-melt kua nplaumAS-HMT-6,
Sib tov 5-10% cyclohexanone rau cov kua nplaum vim yog cov kua nplaum tuab heev yuav ua rau lub ntsej muag lub ntsej muag, luam tawm txog 10 zaug, tom qab txhua qhov luam ntawv yuav tsum ci kom qhuav ntawm qhov chaw, tom qab ntawd cov ntawv luam tawm hloov pauv tiav.
Kauj ruam 4:Muab daim ntawv lo ua tiav rau hauv qhov cub kom ci, thawj zaug ci 30min ntawm qhov kub thiab txias
Ci rau 65 feeb, tom qab ntawd ci rau 40 feeb ntawm qhov kub ntawm 110 degrees.
KAUJ RUAM 5: Sau daim ntawv hloov chaw ntawm daim ntaub. Siv tshuab xovxwm kub nias daim ntawv lo rau ntawm daim ntaub, qhov kub thiab txias 160 degree @ 15 vib nas this rau kev hloov mus rau ob sab, tom qab nws txias, rhuav daim ntawv.
