Polycarbonate yog ib pawg ntawm cov thermoplastics uas muaj ib qho qauv thiab ntau yam kev siv. Cov khoom tau txais nws lub npe los ntawm derivatives ntawm carbonic acid - carbonates. Ua tsaug rau kev txhim kho cov thev naus laus zis niaj hnub no, cov khoom siv polycarbonate zoo dua li nws cov khoom siv hauv kev tsim kho.
Polycarbonate, nws cov khoom muaj qhov txawv ntawm lub zog siab thiab tawv, yog siv rau kev tsim kho ntawm ntau yam qauv - ob qho tib si loj hauv kev lag luam thiab cov qauv me me. Nyob rau tib lub sijhawm, muaj pes tsawg leeg ntawm cov nplooj ntawv polycarbonate tuaj yeem ntim cov iav fiber ntau los txhim kho cov khoom siv kho tshuab.
Nyob hauv lub neej txhua hnub, polycarbonate yog siv los tsim cov awnings, CDs, canopies, laj kab, arbors, tsev cog khoom, ru tsev, lo ntsiab muag, thiab lwm yam. Polycarbonate nplooj ntawv yog muag nyob rau hauv unlimited ntau thiab ntau yam.
Daim ntawv polycarbonate manufacturers tsim obhom:
- Cellular polycarbonate. Cov khoom siv - cov qauv muaj zog, tsis muaj qhov hnyav, zoo thermal rwb thaiv tsev thiab plasticity. Sawv cev rau hollow multilayer panels, uas txuas nrog ntsug stiffening tav.
- Monolithic polycarbonate. Cov no yog cov khoom vaj huam sib luag, cov khoom uas yog lub zog siab tshaj plaws ntawm txhua qhov kev lag luam ntawv-hom yas thiab kev ua haujlwm kub kub txwv.
Cellular polycarbonate yog tsim los ntawm melting polymer granules. Lub resulting sib tov yog squeezed tawm los ntawm ib tug tej yam duab, uas txiav txim siab tus tsim thiab qauv ntawm daim ntawv. Ntau yam xim ntawm polycarbonate ho nthuav dav ntawm cov khoom siv hauv tsev no. Nws raug tso cai siv ib qho tshwj xeeb muaj pes tsawg leeg rau nws qhov chaw, uas yuav tsis khaws cov condensate tawm.
Khoom ntawm polycarbonate:
- tawm tsam cov tshuaj phem;
- ductility thiab cuam tshuam lub zog;
- siab optical transparency;
- zoo suab rwb thaiv tsev;
- tiv taus huab cua hnyav thiab tshav ntuj;
- flammable;
- siab hnav tsis kam;
- lub teeb yuag.
Cellular polycarbonate yuav tsum tau sau tseg nyias, cov khoom uas qhia txog kev nyab xeeb hluav taws kub. Thaum ib yam khoom ua los ntawm polycarbonate ignites, lub hlwb nyob rau hauv nws panels pab tshem tawm cov khoom combustion thiab pa luam yeeb. Txawm li cas los xij, cov khoom nws tus kheej tsis yogkis hluav taws thiab tsis tsim cov dej kub poob. Thaum lub sij hawm combustion, nws swells, nyias thiab lub teeb threads tshwm, uas instantly txias nyob rau hauv huab cua.
Polycarbonate. Nta thiab Daim Ntawv Thov
Vim nws lub teeb, yoog raws, xim ntau yam, lub zog, yooj yim ntawm kev teeb tsa, ruaj khov ntawm cov khoom thiab lawv cov khoom siv kho qhov muag zoo heev, polycarbonate yog siv rau hauv qab no:
- kev tsim kho - glazing ntawm cov qauv thiab cov qauv rau kev ua liaj ua teb thiab kev lag luam;
- decorative design - sab hauv partitions, canopies, qhov rooj, khw qhov rais;
- sab nraum zoov tshaj tawm - cov paib, tshaj tawm xov xwm loj, ntawv tshaj tawm, sawv, thawv, pedestals.
