Vulcanizing tus neeg sawv cev
1. Vulcanizing tus neeg saib xyuas kev ua tau zoo tuaj yeem muab faib ua hom zoo tib yam thiab daj tsis kam Nws daim ntawv thov muaj xws li ob yam hauv qab no;
2. Ordinary non yellowing curing agent, siv rau qee yam khoom tsis raug silica gel nrog cov xim sib sib zog nqus lossis xim tsis tshua muaj;
3. Anti yellowing vulcanizing tus neeg sawv cev yog siv rau cov khoom uas yuav tsum tau nthuav tawm, muaj xim sib zog thiab ci dua, thiab muaj cov kev xav tau ntau dua rau cov xim. Qhov zoo ntawm vulcanizing tus neeg saib xyuas muaj feem xyuam nrog hydrogen uas muaj cov roj silicone. Dow Corning hydrogen muaj cov roj silicone muaj tus nqi hydrogen ntau dua 1.6; Cov nyhuv zoo dua thaum cov kua qaub qis dua.
Txheej txheem:
Thaum lub sij hawm molding ntawm pob tshab silica gel cov khoom, cov xim ntawm pob tshab silica gel cov khoom tig daj tom qab molding. Cov teeb meem tseem ceeb yog:
1. Pwm kub siab dhau lawm;
2. Lub sijhawm kho tau ntev dhau lawm;
3. Tom qab cov tshuaj sulfur ntxiv.
Qhov zoo ntawm raw cov ntaub ntawv tsis zoo heev:
Qee zaum peb ntxiv cov tshuaj tiv thaiv yellowing vulcanizing rau cov roj hmab, tab sis cov khoom pob tshab silica gel tseem zoo li daj tom qab molding. Tej zaum nws yuav yog tias lub peev xwm los tiv thaiv yellowing ntawm cov ntaub ntawv raw yog qhov tsis zoo. Nws raug pom zoo kom hloov ncaj qha cov ntaub ntawv raw nrog tsis zoo los tiv thaiv yellowing peev xwm.
