Chii chinonzi PVB?& Chii chinodzokororwazve PVB?
Polyvinyl butyral (kana PVB) iresin inonyanya kushandiswa kune zvikumbiro zvinoda kusunga kwakasimba, kujeka kwemaziso, kunamatira kune akawanda maficha, kusimba uye kuchinjika.Yakagadzirirwa kubva ku polyvinyl doro nekuita nebutyraldehyde.Iyo huru yekushandisa ndeye laminated kuchengetedza girazi remota windshields.Mazita ekutengesa ePVB-mafirimu anosanganisira KB PVB, Saflex, GlasNovations, Butacite, WINLITE, S-Lec, Trosifol uye EVERLAM.PVB inowanikwawo se 3D printer filament iyo yakasimba uye inodzivirira kupisa kupfuura polylactic acid (PLA).Polyvinyl butyral (PVB) inoonekwa seacetal uye inoumbwa kubva pakuita kwealdehyde uye doro.Chimiro chePVB chinoratidzwa pazasi, asi kazhinji hachiitwe nenzira iyi chaiyo.Inogadzirwa nenzira yekuti iyo polymer musanganiswa wePVB, polyvinyl doro (PVOH), uye polyvinyl acetate zvikamu sezvakaratidzwa mumufananidzo.Huwandu hwezvikamu zvezvikamu izvi zvinodzorwa asi dzinowanzo kugoverwa zvisina tsarukano kuburikidza neketani yemamorekuru.Zvimiro zvemapolymers zvinogona kuvandudzwa nekudzora mareshiyo ezvikamu zvitatu.
Yakadzokororwa PVB (RPVB), inozivikanwawo seRecycled Polyvinyl Butyral, idehwe rekugadzira rakagadzirwa nekudzoreredza mahwindi emhepo kubva kumotokari dzakasiiwa dzekuvaka girazi.Sechinhu chepolymeric, iyi post-mutengi PVB dehwe rinonyanya kushandiswa neupholstery, kurongedza, uye maindasitiri emotokari.
Sei PVB yakadzokororwa ichive chinhu chakasimba?
1.Recycled PVB carbon footprint is 25 times yakaderera pane mhandara PVB.Wedzera hutano hwezvinhu zvezvigadzirwa zvedu.Mvura shoma, hapana makemikari ane chepfu, uye eco regulation yakaitwa.
2.Nekuparadzanisa, kuchenesa, nekugadzirisa, PVB yakashandiswa zvakare inogona kushandurwa kuita zvinhu zvakapedzwa.Kuburikidza nekumwe kugadzira, mafirimu akasiyana-siyana akapfava, shinda dzakavharwa, uye zvinhu zvinopupuma zvinogadzirwa.
3.Kushandisa chinhu ichi kunoderedza carbon footprint ye precoat ne 80% kana ichienzaniswa neyekare latex.Ese akajairwa diki tuff kapeti mataira ave kugadzirwa neayo precoat, achidzikisa kukanganiswa kwezvakatipoteredza zvakanyanya.
4. Yakagadzirwazve PVB inogadzirwa nekudzokorora magirazi emhepo kubva kumotokari dzakasiiwa dzekugadzira magirazi.Saka kushandura iyi yaimbove isingagadzirike zvakare kuita yemhando yepamusoro mbishi.Izvi zvinoreva kuderedza marara emagetsi, izvo zvakanaka kune zvakatipoteredza.Panguva imwecheteyo tendeukira kumarara kune sosi, izvo zvakare zvakanaka kune yedu pasi.
Sei tichisarudza zvakashandiswazve PVB zvinhu?
1. Iyo PVB zvinhu ndeye Dirt-proof uye Moisture-proof, zviri nyore kwazvo kuchenesa mabhegi edu.
2. Sezvo zvinhu zvePVB zvakasimba zvikuru.Zvigadzirwa zvakagadzirwa kubva kuPVB yakadzokororwa zvakasimba uye zvinoputsika.
3.Recycled PVB dehwe rakasiyana chimiro rinopa versatility nokuda kwakakura kushandiswa, uye ndiyo yakanakisisa imwe nzira PVC.
4. Yakagadzirwazve PVB inoshamwaridzana uye haina ngozi kumunhu nekudzikisa kabhoni tsoka uku uchiwedzera hutano hwezvigadzirwa.Iyo haisanganisi makemikari ane chepfu seDimethylformamide (DMF) uye Dimethylfumarate (DMFu).
5. Yakagadzirwazve PVB haina Hapana BPA, Hapana Plasticizers, Hapana Phthalates, yakachengeteka.
6. Recycled PVB inoora, chinhu eco-ushamwari zvinhu.
7. Zvigadzirwa zvakagadzirwa kubva kuPVB yakadzokororwa zvinotaridzika zvakanyanya, zvakatwasuka, zvakanaka, zvisingapindi mvura uye zvinogara.Vanhu vazhinji vanoda zvinhu izvi.
8. Mutengo wePVB yakadzokororwa hauna kunyanya kukwirira.Saka vatengi vazhinji vanogona kugamuchira mutengo wezvigadzirwa wakagadzirwa kubva kuPVB yakadzokororwa.
