Yini i-PVB ?& Yini i-PVB egaywe kabusha?
I-Polyvinyl butyral (noma i-PVB) iyinhlaka esetshenziselwa kakhulu izinhlelo zokusebenza ezidinga ukubopha okuqinile, ukucaca okubonakalayo, ukunamathela ezindaweni eziningi, ukuqina kanye nokuguquguquka.Ilungiswa kusuka ku-polyvinyl alcohol ngokusabela nge-butyraldehyde.Isicelo esikhulu ingilazi yokuphepha e-laminated yama-windshields emoto.Amagama okuhweba amafilimu e-PVB ahlanganisa i-KB PVB, i-Saflex, i-GlasNovations, i-Butacite, i-WINLITE, i-S-Lec, i-Trosifol ne-EVERLAM.I-PVB iphinde itholakale njenge-3D printer filament enamandla futhi imelana nokushisa kune-polylactic acid (PLA).I-Polyvinyl butyral (PVB) ithathwa njenge-acetal futhi yakhiwe ngenxa yokusabela kwe-aldehyde notshwala.Isakhiwo se-PVB siboniswe ngezansi, kodwa ngokuvamile ayenziwa ngaleli fomu.Yenziwe ngendlela yokuthi i-polymer iyingxube ye-PVB, i-polyvinyl alcohol (PVOH), namasegimenti e-polyvinyl acetate njengoba kukhonjisiwe emfanekisweni.Amanani ahlobene alawa masegimenti alawulwa kodwa ngokuvamile asatshalaliswa ngokungahleliwe ngochungechunge lwamangqamuzana.Izakhiwo zama-polymers zingenziwa kahle ngokulawula izilinganiso zamasegimenti amathathu.
I-Recycled PVB (RPVB), eyaziwa nangokuthi i-Recycled Polyvinyl Butyral, iyisikhumba sokwenziwa esenziwe ngokugaywa kabusha kwama-windshields kusuka ezimotweni zokwakha ezilahliwe.Njengempahla ye-polymeric, lesi sikhumba se-post-consumer PVB sisetshenziswa kakhulu izimboni ze-upholstery, ukupakisha, nezimboni zezimoto.
Kungani i-PVB egaywe kabusha iyinto eqhubekayo?
1.Izigxivizo zekhabhoni ze-PVB ezenziwe kabusha zingaphansi izikhathi ezingama-25 kune-PVB emsulwa.Khulisa impilo ebonakalayo yemikhiqizo yethu.Amanzi amancane, awekho amakhemikhali anobuthi, kanye nokulawulwa kwe-eco kwenziwa.
2.Ngokuhlukanisa, ukuhlanza, nokulungisa, i-PVB egaywe kabusha ingaguqulwa ibe izinto eziqediwe.Ngokuqhubeka nokukhiqiza, kwenziwa amafilimu athambile ahlukahlukene, izintambo eziboshiwe, nezinto eziphuma amagwebu.
3.Ukusebenzisa le nto kunciphisa i-carbon footprint ye-precoat ngo-80% uma kuqhathaniswa ne-latex evamile.Wonke amathayela okhaphethi we-tuff ajwayelekile manje akhiqizwa ne-precoat yawo, ehlisa umthelela wendawo kakhulu.
4. I-PVB egaywe kabusha yenziwa ngokugaywa kabusha kwama-windshield kusuka ezimotweni zokwakha ezilahliwe.Ngakho-ke ukuguqula lokhu okubalulekile okwakungaphinde kusetshenziswe kabusha kube impahla eluhlaza yekhwalithi ephezulu.Lokho kusho ukwehlisa udoti wamawindi omoya, okuhle endaweni yethu.Ngesikhathi esifanayo phendukela kumfucumfucu emthonjeni, lokho nakho kuhle emhlabeni wethu.
Kungani sikhetha izinto ezigaywe kabusha ze-PVB?
1. Izinto ze-PVB azikwazi ukungcola futhi zinomswakama, kulula kakhulu ukuhlanza izikhwama zethu.
2. Njengoba impahla ye-PVB inamandla kakhulu.Imikhiqizo eyenziwe nge-PVB egaywe kabusha iqinile futhi iyaphahlazeka.
3.Isakhiwo esiyingqayizivele se-PVB esenziwe kabusha sesikhumba sinikeza ukuguquguquka kwezinhlelo zokusebenza ezibanzi, futhi siyindlela engcono kakhulu kune-PVC.
4. I-PVB egaywe kabusha i-eco-friendly futhi ayinabungozi kumuntu ngokunciphisa i-carbon footprint ngenkathi ikhulisa impilo yezinto ezibonakalayo yemikhiqizo.Akubandakanyi amakhemikhali anobuthi njenge-Dimethylformamide (DMF) ne-Dimethylfumarate (DMFu).
5. I-PVB egaywe kabusha ayiqukethe i-No BPA, No Plasticizers, No Phthalates, iphephile.
6. I-PVB egaywe kabusha iyonakala, iyinto evumelana nemvelo.
7. Imikhiqizo eyenziwe nge-PVB egaywe kabusha ibukeka iwubukhazikhazi kakhulu, iqondile, mihle, ingangeni manzi futhi ihlala isikhathi eside.Abantu abaningi bayayithanda le nto.
8. Izindleko ze-PVB egaywe kabusha aziphezulu kangako.Ngakho-ke abathengi abaningi bangamukela intengo yemikhiqizo eyenziwe nge-PVB egaywe kabusha.
