Kev siv ntawm PVB
1. Cov zaj duab xis nyias yog siv los ua cov khoom siv sandwich kom muaj kev ruaj ntseg iav.Cov iav muaj kev nyab xeeb yog qhov zoo thiab muaj lub zog muaj zog.Nws yog dav siv nyob rau hauv aviation thiab tsheb teb.
2. Nws yog siv los tsim cov hlau hauv qab coatings thiab cov xim txias uas muaj zog adhesion thiab dej tsis kam nrog muaj zog adhesion thiab dej tsis kam.
3. Nws yog siv los tsim ib lub ci ci paj paj ntawv, uas tuaj yeem hloov cov ntawv paj paj.Kev lag luam resin yog siv los tsim cov yas crusher rau cov hlau uas tsis yog-ferrous xws li hlau thiab txhuas, uas tuaj yeem sib phim rau ntau yam nplaum.Nws yog dav siv rau kev sib txuas ntawm ntoo, ceramic, hlau, yas, tawv, txheej ntawm cov ntaub ntawv siab.
4. Siv los ua cov tshuaj kho cov ntaub thiab cov ntaub qhwv lub raj.Kev lag luam zaub mov yog siv los ua cov khoom ntim tshuaj lom.
5. Kev lag luam papermaking yog siv los ua cov ntawv kho mob.Tsis tas li ntawd, nws tuaj yeem siv los tsim cov khoom tiv thaiv shrinkables, cov neeg ua haujlwm nruj thiab lwm yam khoom siv dej tsis zoo.
6. Nws tuaj yeem siv rau kev sib tw ntawm kev lag luam luam ntawv, concave printing, convex printing, silk net printing, heat transfer, vim nws yog yaj hauv cawv thiab tsis muaj tshuaj lom, lub foob tsis nyob hauv qhov tsw, uas tuaj yeem siv tau. nyob rau hauv kev lag luam khoom noj khoom haus uas yog rhiab rau cov ntxhiab tsw hauv kev lag luam khoom noj.Xws li tshuaj yej / luam yeeb.Vim hais tias cov resin yog hom cedic, nws muaj cov adhesion zoo heev ntawm lub iav nrog lub zog yin ion, uas yog tshwj xeeb tshaj yog haum rau iav phaj kho kom zoo nkauj silk prints.
