Y Plastic, lossis yas, yog cov khoom siv organic raws li cov tshuaj macromolecular - polymers. Kev xav tias yas yog cov khoom siv ruaj khov thiab zoo tshaj li cov yas yog qhov yuam kev. Qhov txawv ntawm cov tswv yim no tsuas yog nyob rau hauv lawv lub npe. Hom yas, nws hom, kev faib tawm, sau npe, thaj chaw siv yog loj.
cov khoom yas tau ruaj khov rau hauv peb lub neej. Plastics raws li hluavtaws polymers yog tshwj xeeb tshaj yog dav siv. Cov txheej txheem tsim khoom yog kev hloov pauv ntawm cov khoom siv nyob rau hauv lub zog ntawm cov cua sov thiab lub siab los ntawm cov kua hauv lub xeev mus rau lub xeev khoom. Txoj kev loj hlob ntawm plastics pib nrog kev siv cov khoom xyaw ntuj. Tom qab ntawd lawv tau hloov kho cov khoom siv tshuaj lom neeg. Tam sim no, rau kev tsim cov yas, tag nrho cov khoom siv hluavtaws yog siv - polyethylene, polyvinyl chloride, epoxy. Thiab qhov tsis pub leej twg paub yog raws li hauv qab no: yooj yim ntawm kev tsim khoom, kev ua tau zoo, tus nqi pheej yig.
Key Features
Hom thiab cov khoom ntawm cov yas, nws cov weldabilityFeem ntau yog nyob ntawm cov polymer uas nws tau ua. Txhua yam additives, additives, stabilizers, pigments, organic thiab inorganic fibers kuj muaj feem xyuam rau lub cev thiab mechanical yam ntxwv ntawm plastics. Qee qhov, piv txwv li, tiv thaiv yas los ntawm hluav taws xob ultraviolet.
Mas cov khoom yog dawb los yog pob tshab. Nrog rau qhov sib ntxiv ntawm dyes, yas tuaj yeem tau txais txhua yam xim. Ua li no, ib daim iav yas tuaj yeem tsim tau. Plastics feem ntau yog cov khoom siv sib xyaw thiab cov khoom sib xyaw. Yas muaj qhov ntom ntom. Resistant rau acids thiab alkalis. Nws muaj tsawg thermal thiab hluav taws xob conductivity. Feem ntau hom yog cov txheej txheem yooj yim. Qhov no tso cai rau kev tsim cov khoom molded los ntawm cov khoom siv raw, nrog rau kev siv cov ntawv yas, sib txuas cov thermoforming nrog cov tshuab ua haujlwm.
siv yas
Cov txheej txheem ntawm cov yas yog qhov loj. Pib nrog kev siv hauv nkoj tsim, tsim dav hlau, xaus nrog kev ua liaj ua teb, tshuaj thiab lub neej txhua hnub. Cov hom yas yog amazing. Cov duab qhia tsuas yog ib feem me me ntawm cov khoom:
- Plastics yog siv dav hauv kev tsim khoom ntawm cov tsheb loj, nrog rau kev txiav sab hauv.
- Txoj kev loj hlob ntawm kev ua liaj ua teb suav nrog kev siv cov yas hauv av reclamation, tsim cov khoom ntim rau kev khaws cov khoom ua liaj ua teb, kev tsim cov vaj tsev nyob thiab tsev cog khoom.
- Ntau yam cuab yeej kho mob, cov khoom siv tshwj xeeb, ntim khoomrau tshuaj yog ua los ntawm yas.
- Hauv kev tsim kho, cov no yog cov kav hlau-yas thiab fittings. Ib qho ntxiv rau iav yog tsim los ntawm lub teeb lossis pob tshab yas.
- Nyob hauv lub neej txhua hnub - kev siv txhua yam ntim, fwj, hnab, khoom ua si menyuam yaus thiab ntau ntxiv.
pob tshab yas
Plastic hom muaj xws li thermoplastic PVC, uas yog siv rau cov ntaub ntawv. Nws yog siv rau hauv kev tsim kho, kev tshaj tawm sab nraum zoov thiab lwm yam kev lag luam. Ib hom ntawv cov khoom yog pob tshab yas. Nyob ntawm qhov muaj peev xwm kis tau tus mob, cov khoom tuaj yeem thaiv lossis kis tau qee yam ntawm cov kab hluav taws xob ultraviolet. Nws tuaj yeem yog cov ntaub ntawv pob tshab thiab cov xim pob tshab.
Hom pob tshab yas yog plexiglass, polycarbonate, polystyrene, polyester iav, pob tshab PVC nplooj ntawv. Ua ntej tshaj plaws, lawv muaj kev cuam tshuam resistant. Ntau ruaj yog polycarbonate. Polyester iav yog suav tias yog qhov elastic tshaj plaws. Lub teeb kis tau tus mob yog siab dua rau plexiglass, nws yog cov pob tshab thiab meej tshaj plaws, nws tau ua tiav zoo. Cov yas pob tshab yog siv rau glazing qhov rais, tsom iav thiab tub ceev xwm shields, ua lub raj mis yas. Cov yas pob tshab tuaj yeem muaj qhov sib txawv.
YPlastic facades
Hom yas rau facades muab faib ua daim ntawv thiab yob. Cov ntaub ntawv nyuaj thiab cov khoom siv yog yassiab. Txias lossis nruab nrab siab yob yas yog qhov zoo thiab pheej yig dua li cov ntawv yas. Cov khoom no hauv cov yob zoo li PVC zaj duab xis. Nws kuj yog siv rau hauv kev tsim cov rooj tog zaum pem hauv ntej.
Hom yas rau chav ua noj muaj qhov sib txawv. Qee qhov yog tsim los ntawm chipboard, thiab nws yog pheej yig dua li lub hauv paus ntawm MDF. Cov ntawv yas yog thermally ruaj khov, nws tsis raug khawb, chips, cuam tshuam, tsis deform, tsis ploj lossis ploj. Cov khoom tsis tev tawm ntawm lub hauv paus, tsis ntshai ntawm noo noo, thiab yooj yim los ntxuav. Qhov tsis zoo ntawm cov ntsiab lus façade yog tias lawv tuaj yeem tsuas yog txawm tias tsis muaj milling, thiab du hauv kev ntxhib los mos.
Tiav
Hnub no, yas tseem yog cov khoom siv hauv tsev nrov. Feem ntau ntau hom yas yog siv rau kev kho kom zoo nkauj hauv chaw ua haujlwm. Tab sis nyob rau hauv lub xub ntiag ntawm kev xav thiab nrog ib tug muaj peev xwm tsim, xws li cov khoom yuav saib zoo nyob rau hauv lub kho kom zoo nkauj ntawm lub tsev apartment. Yas tuaj yeem raug sheathed ntawm txhua qhov chaw, txawm tias nws yog lub qab nthab lossis phab ntsa. Lub ntsiab ntawm cov khoom siv rau lub qab nthab yog PVC panels. Vaj huam sib luag loj sib txawv. Cov ntsiab lus sib cais yog sib cuam tshuam nrog kev pab cuam ntawm cov tav tav (lub vaj huam sib luag muaj qhov zawj ntawm ib sab, thiab ib qho ntsia hlau loj ntawm lwm qhov). Cov khoom siv yog lub teeb thiab nyab xeeb. Yooj yim thauj thiab yooj yim rau nruab.
Yas, muaj dej tsis kam, yog siv hauv chav dej thiab thaum lub balconies. Nws yog siv rau kev teeb tsa cov nqes hav thiab ua tiav ceilings. Nrog kev xaiv zoo thiab muaj peev xwm ntawm cov yas, koj tau txais ib qho chaw nkag zoo heev. Cov vaj huam sib luag yas tuaj yeem frostedlos yog glossy, xyaum ntoo lossis pob zeb.
Qhov zoo thiab qhov tsis zoo
Hauv qee thaj chaw ntawm tib neeg kev ua haujlwm, ntau hom yas tau pom zoo siv los ntawm Ministry of He alth:
- Huab cua resistant khoom. Nws muaj hluav taws xob rwb thaiv tsev zoo thiab tsis yog-flammable.
- Yooj yim rau ua. Yooj yim rau weld thiab kua nplaum. tuaj yeem txiav thiab ua raws li qhov xav tau.
- Cov khoom pheej yig. Rau ib ntev lub sij hawm khaws nws thawj tsos. Tsis ntshai moist.
- Nws muaj xim nplua nuj. Daim ntawv pob tshab yas muaj cov khoom poob siab-resistant thiab hluav taws-resistant. Los ntawm nws koj tuaj yeem tau txais cov khoom ntawm ntau yam duab.
- Foamed PVC tiv taus qhov kub thiab txias. Thaum ua tiav chav tsev, nws plays lub luag hauj lwm ntawm lub suab thiab cua sov insulator. Haum rau awnings, txoj kev paib, paib, advertising khoom.
Zoo ib yam khoom, yas muaj qee qhov tsis zoo:
- Muaj feem cuam tshuam rau ntau cov kuab tshuaj organic.
- Cov khoom yas yuav deform nyob rau hauv hnyav loads los yog kub kub.
