PVB yog dab tsi? & Dab tsi yog recycled PVB?
Polyvinyl butyral (los yog PVB) yog cov resin feem ntau siv rau cov ntawv thov uas yuav tsum tau muaj zog khi, kho qhov muag pom tseeb, adhesion rau ntau qhov chaw, toughness thiab yooj.Nws yog npaj los ntawm polyvinyl cawv los ntawm cov tshuaj tiv thaiv nrog butyraldehyde.Daim ntawv thov loj yog laminated kev nyab xeeb iav rau tsheb windshields.Cov npe lag luam rau PVB-films suav nrog KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol thiab EVERLAM.PVB kuj muaj raws li 3D tshuab luam ntawv filament uas muaj zog thiab kub resistant dua polylactic acid (PLA).Polyvinyl butyral (PVB) yog suav tias yog ib qho acetal thiab yog tsim los ntawm cov tshuaj tiv thaiv ntawm aldehyde thiab cawv.Cov qauv ntawm PVB yog qhia hauv qab no, tab sis nws feem ntau tsis ua raws nraim li daim ntawv no.Nws yog tsim nyob rau hauv ib txoj kev xws li cov polymer yog sib tov ntawm PVB, polyvinyl cawv (PVOH), thiab polyvinyl acetate ntu raws li qhia hauv daim duab.Cov nqi txheeb ze ntawm cov ntu no tau tswj hwm tab sis lawv feem ntau muab faib los ntawm cov saw hlau molecular.Cov khoom ntawm cov polymers tuaj yeem ua kom zoo los ntawm kev tswj xyuas qhov sib piv ntawm peb ntu.
Recycled PVB (RPVB), tseem hu ua Recycled Polyvinyl Butyral, yog cov tawv hluavtaws ua los ntawm cov khoom siv rov ua dua tshiab los ntawm cov tsheb tso tseg lub tsev iav.Raws li cov khoom siv polymeric, cov khoom siv tom qab PVB tawv feem ntau yog siv los ntawm cov khoom siv, ntim khoom, thiab kev lag luam tsheb.
Vim li cas PVB rov ua dua yog cov khoom siv ruaj khov?
1.Recycled PVB carbon hneev taw yog 25 npaug qis dua PVB nkauj xwb.Ua kom cov khoom noj qab haus huv ntawm peb cov khoom.Tsawg dej, tsis muaj tshuaj lom, thiab kev tswj hwm eco tau cog lus.
2.Los ntawm kev sib cais, ua kom huv, thiab hloov kho, rov ua dua PVB tuaj yeem hloov mus rau hauv cov khoom tiav.Los ntawm kev tsim khoom ntxiv, ntau cov yeeb yaj kiab mos, cov xov paj coated, thiab cov ntaub ntawv foaming yog tsim.
3.Siv cov khoom no txo cov pa roj carbon hneev taw ntawm precoat los ntawm 80% piv rau cov tshuaj latex.Tag nrho cov txheej txheem micro tuff cov ntaub pua plag yog tam sim no tsim nrog nws cov precoat, txo cov kev cuam tshuam ib puag ncig.
4. Recycled PVB yog tsim los ntawm kev siv lub tshuab ua cua sov los ntawm cov tsheb tso tseg lub tsev iav.Yog li transforming no ib zaug unrecyclable khoom mus rau hauv high quality raw khoom.Qhov ntawd txhais tau hais tias txo cov cua ntsawj ntshab pov tseg, uas yog qhov zoo rau peb ib puag ncig.Nyob rau tib lub sij hawm tig mus rau cov pov tseg mus rau ib qho chaw, uas kuj zoo rau peb ntiaj chaw.
Vim li cas peb xaiv cov khoom siv PVB rov ua dua?
1. Cov khoom siv PVB yog Dirt-proof thiab Moisture-proof, nws yooj yim heev los ntxuav peb lub hnab.
2. Vim tias cov khoom siv PVB muaj zog heev.Cov khoom tsim los ntawm cov khoom siv rov ua dua PVB yog qhov muaj zog thiab tsim nyog.
3.Recycled PVB tawv cov qauv tshwj xeeb muab ntau yam rau kev siv dav, thiab nws yog lwm txoj hauv kev zoo tshaj plaws rau PVC.
4. Recycled PVB yog eco-phooj ywg thiab tsis muaj teeb meem rau tib neeg los ntawm kev txo cov pa roj carbon hneev taw thaum ua kom cov khoom noj qab haus huv ntawm cov khoom.Nws tsis suav nrog cov tshuaj lom neeg xws li Dimethylformamide (DMF) thiab Dimethylfumarate (DMFu).
5. Recycled PVB tsis muaj BPA, Tsis muaj Plasticizers, Tsis muaj Phthalates, nws muaj kev nyab xeeb.
6. Recycled PVB yog degradable, nws yog eco-friendly khoom.
7. Cov khoom tsim los ntawm cov khoom siv rov ua dua tshiab PVB zoo li khoom kim heev, upright, zoo nkauj, tsis muaj dej thiab ruaj khov.Cov neeg feem coob nyiam cov khoom no.
8. Tus nqi ntawm PVB rov ua dua tsis yog siab heev.Yog li cov neeg siv khoom feem ntau tuaj yeem lees txais cov khoom lag luam tus nqi tsim los ntawm PVB rov ua dua tshiab.
