Tom qab ob lub Cheebtsam A thiab B ntawm textile screen printing silicone khoom yog sib tov, ib tug flowing kua silicone xeev yuav tsim. Hauv qab no yog cov lus piav qhia ntxaws ntawm lub xeev sib xyaw:
1. Kev tshwm sim
Lub tshuab luam ntawv sib xyaw ua ke ntawm silicone yog nyob rau hauv lub pob tshab los yog cov kua hauv lub xeev, nrog fluidity, uas yooj yim rau dispensing, luam ntawv thiab lwm yam haujlwm.
2. Lub cev muaj zog
Fluidity:Cov khoom sib xyaw silicone muaj fluidity zoo thiab muaj peev xwm ua tau zoo dhau los ntawm kev tshuaj ntsuam luam ntawv lossis cov khoom siv xa tawm kom ntseeg tau tias qhov sib xws thiab raug ntawm luam ntawv lossis xa tawm.
viscosity:Nyob ntawm seb cov khoom lag luam tshwj xeeb thiab cov txheej txheem yuav tsum tau ua, cov khoom sib xyaw silicone yuav muaj cov viscosities sib txawv. Nyias silicone yog tsim nyog rau kev luam cov kab zoo los yog nyias txheej, thaum thicker silicone yog ntau haum rau luam ntawv tuab kab los yog tuab txheej.
Kev ruaj ntseg:Cov khoom sib xyaw silicone muaj qee qhov kev ruaj ntseg ntawm chav tsev kub thiab tuaj yeem tswj tau nws cov fluidity thiab luam ntawv ua tau zoo rau qee lub sijhawm. Txawm li cas los xij, nrog rau qhov kub thiab txias los yog ncua sij hawm, qhov fluidity ntawm silicone yuav maj mam txo, yog li nws yog ib qho tsim nyog yuav tsum tau npaj cov kua nplaum kom tsim nyog thiab siv sij hawm raws li qhov kub thiab txias thiab kev tsim khoom.
3. Cov khoom siv tshuaj
Curing tshuaj tiv thaiv:Cov khoom sib xyaw silicone yuav raug kho cov tshuaj tiv thaiv nyob rau hauv cov cua kub kom tsim cov txheej silicone nrog qee lub zog thiab elasticity. Cov txheej silicone kho tau zoo adhesion thiab hnav tsis kam, thiab tuaj yeem ua raws li cov ntaub ntawv ruaj khov.
Environmental kev ua tau zoo:Cov khoom siv silicone sib xyaw feem ntau ua tau raws li kev tiv thaiv ib puag ncig, tsis muaj tshuaj lom thiab tsis muaj ntxhiab, thiab yuav tsis ua rau tib neeg lub cev thiab ib puag ncig. Nyob rau tib lub sijhawm, cov txheej txheem kho silicone kuj muaj cov huab cua tsis zoo thiab tshuaj lom neeg ruaj khov, thiab tuaj yeem tswj tau nws qhov kev ua tau zoo thiab zoo li lub sijhawm ntev.
4. Kev ceev faj ua haujlwm
Mixing ratio:Qhov sib xyaw ntawm cov khoom A thiab B yuav tsum tau ua nruj me ntsis raws li cov lus qhia ntawm cov khoom kom ntseeg tau tias cov nyhuv curing thiab cov khoom zoo.
Lub tshuab nqus tsev degassing:Cov sib xyaw silicone xav tau lub tshuab nqus tsev degassed kom tshem tawm npuas thiab impurities kom ntseeg tau tias qhov sib xws thiab qhov tseeb ntawm kev luam ntawv lossis xa tawm.
Cia tej yam kev mob:Cov khoom sib xyaw silicone yuav tsum tau siv nyob rau hauv lub sijhawm teev tseg thiab khaws cia rau hauv qhov chaw txias thiab qhuav, tsis txhob tshav ntuj ncaj qha thiab qhov kub thiab txias.
Hauv cov ntsiab lus, cov ntaub ntawv luam tawm cov khoom siv silicone yog cov pob tshab lossis cov kua dej ntws tawm tom qab ob lub ntsiab lus A thiab B sib xyaw, thiab muaj cov yam ntxwv ntawm fluidity, stability thiab kev tiv thaiv ib puag ncig. Thaum siv, xyuam xim rau cov teeb meem xws li kev sib tov sib xyaw, lub tshuab nqus tsev degassing thiab kev cia khoom kom ntseeg tau tias qhov zoo thiab muaj txiaj ntsig ntawm kev luam ntawv lossis xa tawm.
