Hnub no, muaj ntau yam khoom siv hauv tsev thiab pheej yig rau kev tsim cov tsev niaj hnub. Ib qho nrov tshaj plaws yog polycarbonate, los yog, raws li nws tseem hu ua, polycarbonate iav. Dab tsi yog nws thiab siv qhov twg?
Kev piav qhia
Polycarbonate iav yog cov khoom siv hluavtaws uas muaj tshuaj lom neeg muaj carbonic acid polyester thiab phenols. Cov khoom siv raw, uas yog tsim rau hauv cov ntawv tiav, zoo li pob tshab granules hauv cov qauv.
Ntawm ntawm kev muag khoom koj tuaj yeem nrhiav cellular lossis monolithic ntawv yas. Nws tuaj yeem dyed rau hauv cov xim sib txawv thiab muaj qhov sib txawv ntawm cov pob tshab.
Properties
Cov khoom tuaj yeem hu ua universal, txij li cov yam ntxwv uas nws muaj ua rau nws xyaum ua kom tsis muaj zog:
- cuam tshuam;
- ua haujlwm kub ntawm -45 txog +120 degrees;
- transparency;
- ua haujlwm load ntawm 60 txog 120 kg / m;
- yas, uas yog, haum rau khoov;
- hluav taws kub.
Cov khoom ntawm polycarbonate iav tuaj yeem raug hu ua qhov zoo tagnrho. Txawm li cas los xij, cov khoom siv muaj qhov tsis zoo - thaum siv los yog ntxuav nrog cov tshuaj abrasive, khawb me me tuaj yeem tsim rau ntawm cov khoom siv polymer, uas ua rau nws pos huab. Hmoov tsis zoo, tshem tawm lawv tsis tuaj yeem ua tau. Txawm li cas los xij, abrasion-resistant coated yas ntawv tau raug tsim los siv.
Monolithic polycarbonate
Polymeric yas ntawm hom no zoo li acrylic iav hauv cov yam ntxwv. Txawm li cas los xij, nws cov khoom siv kho tshuab deb tshaj cov iav. Nws yog pob tshab thiab nyob rau tib lub sijhawm zam qhov kub siab thiab qis qis.
Vim nws cov yas siab, monolithic polycarbonate yog siv los tsim cov khoom siv tiv thaiv glazing - shields, laj kab. Tsis tas li ntawd, nws tuaj yeem siv rau glazing vaj tse thiab kev lag luam, chaw ua liaj ua teb, dav hlau, tsheb npav. Cov tsom iav thiab kaus mom hlau yog tsim los ntawm nws.
Vim nws cov cuab yeej plasticity, monolithic polycarbonate iav yog qhov zoo tagnrho rau kev tsim cov khoom nkhaus, xws li canopies lossis domes nrog cov duab plaub, puag ncig lossis square puag. Cov khoom siv dav siv rau kev tsim cov teeb ntawm qhov sib txawv ntawm qhov nyuaj, tiv thaiv kev thaiv ntawm txoj kev, kos npe.
Cellular polycarbonate
Zoo li nosiv los tsim ib lub polymer uas muaj ntau txheej txheej ntawm cov paib tiv thaiv kev tiv thaiv, uas yog sab hauv kev sib txuas los ntawm kev sib txuas ntxiv ntawm cov tav. Nws cov khoom yog melting ntawm granules thiab tsim ntawm ib tug mos mos nrog kev pab los ntawm tshwj xeeb cov ntaub ntawv uas txiav txim seb lub tsos ntawm nplooj.
Lub hom phiaj tseem ceeb ntawm cellular polycarbonate yog siv los ua cov khoom siv vov tsev. Qhov no yog vim nws cov khoom kom tiv taus qhov kub thiab txias, pob tshab thiab tiv taus daus. Vim li no, cov khoom siv tsis yog tsuas yog rau ntsug glazing, tab sis kuj rau kab rov tav. Lub ru tsev rau tsev cog khoom, tsev, tsev, lub vaj lub caij ntuj no, lub qhov rais khw thiab lwm yam khoom zoo nkauj thiab kev tiv thaiv yog ua los ntawm polycarbonate iav.
Cellular polycarbonate yog cov khoom siv hluav taws kub heev, yog li nws muaj npe nrov rau nws qhov hluav taws kub. Qhov no ua rau nws haum rau siv nyob rau hauv ib puag ncig kev phom sij.
Qee lub sij hawm cov khoom yog them nrog ib txheej ntxiv ntawm kev tiv thaiv kev tshwm sim ntawm condensation los yog ultraviolet hluav taws xob. Nyob rau tib lub sijhawm, nws lub neej kev pabcuam nruab nrab yog 10-12 xyoo. Polycarbonate feem ntau siv rau hauv kev tsim kho thiab vim nws cov nqi-zoo thiab muaj.
Installation nuances
Pob tshab polycarbonate iav yog nyob rau hauv qhov kev thov tsis yog rau nws cov yam ntxwv zoo, tab sis kuj rau nws yooj yim ntawm installation, uas txawm tias tus pib tuaj yeem ua tau. Cov khoom siv yog lub teeb thiab cov nplooj ntawv tuaj yeem npogqhov chaw loj heev, yog li kev teeb tsa tsis siv sijhawm ntau dhau. Txawm li cas los xij, nws yog ib qho tseem ceeb rau nruab nws kom raug kom cov polymer kav ntev li ntev tau:
- daim ntawv yas yuav tsum tau muab ntsia hlau rau hauv cov hlau lossis ntoo ncej siv tus kheej tapping screws, nyob rau hauv uas cov ntxhua khaub ncaws yuav tsum muab tso rau;
- yog tias nws yuav tsum siv ob lossis ntau daim ntawv ntawm cov khoom, lub installation yog sib tshooj;
- nyob rau hauv rooj plaub no, ib qho me me ntawm cov sealant yuav tsum tau siv ntawm cov txheej txheem polymer;
- yog tias tsim nyog, txiav rau hauv daim, koj tuaj yeem siv cov cuab yeej ntse - grinder, jigsaw, hacksaw.
Thaum ua haujlwm nrog polycarbonate, koj yuav tsum ua raws li kev ceev faj txog kev nyab xeeb, uas yog: hnav looj tsom iav thiab siv hnab looj tes, vim nws cov npoo tuaj yeem ntse heev.
Cov ntaub ntawv ntawm cov polymer, uas tau them nrog txheej tshwj xeeb tiv thaiv hluav taws xob tiv thaiv ultraviolet, tuaj yeem khaws ncaj qha rau hauv huab cua qhib yam tsis ntshai poob lawv cov khoom. Ib txwm polycarbonate yuav tsum tau khaws cia nyob rau hauv ib lub canopy kom txog thaum installation.
Thaum lub sijhawm ua haujlwm, nws yog txwv tsis pub siv cov ntaub ntawv ntxhib thiab cov khoom siv los ntxuav. Kev ntxuav ntawm qhov chaw tsuas yog tso cai siv cov ntaub txhuam hniav lossis cov ntaub, nrog rau cov tshuaj ntxuav tes. Cov tshuaj ntxuav abrasive tau pom zoo siv rau ntawm cov ntawv resin uas muaj txheej tshwj xeeb los tiv thaiv khawb. Tsis tas li ntawd, tsis txhob siv cov tshuaj detergents uas suav nrog cov khoom xws lixws li alkali, aldehydes, ntsev, isopropanol, ethers.
