Kev tsim kho niaj hnub no tsis tiav yam tsis muaj cov khoom xws li polycarbonate. Cov ntaub ntawv raw khoom no muaj cov khoom tshwj xeeb, yog li ntawd, nws tau ntseeg khov kho qhov qub thiab paub txog ntau yam acrylics thiab iav los ntawm kev tsim kho kev lag luam. Polymer yas muaj zog, siv tau, ruaj, yooj yim rau nruab.
Txawm li cas los xij, feem ntau cov neeg nyob hauv lub caij ntuj sov thiab cov neeg tsim khoom tau txaus siab rau lo lus nug ntawm seb cov khoom no puas kis kab mob ultraviolet (UV rays) . Tom qab tag nrho, nws yog tus yam ntxwv no uas tsis yog lub luag haujlwm rau lub neej ntawm kev ua haujlwm, tab sis kuj rau kev nyab xeeb ntawm yam khoom, kev nyob zoo ntawm ib tus neeg.
Puas yog polycarbonate kis ultraviolet rays thiab vim li cas nws thiaj txaus ntshai?
Qhov ib txwm tshwm sim los ntawm ultraviolet hluav taws xob yog hom hluav taws xob hluav taws xob uas nyob hauv txoj haujlwm ib puag ncig ntawm pom thiab X-hluav taws xob thiab muaj peev xwm hloov pauv cov qauv tshuaj ntawm cov cell thiab cov nqaij. Hauv qhov nyiaj nruab nrab, UV duab hluav taws xob muaj txiaj ntsig zoo, tab sis yog tias muaj ntau dhau lawv tuaj yeem tsim teeb meem:
- Kev kis mus ntev rau lub hnub tshav ntuj tuaj yeem ua rau kub hnyiab ntawm daim tawv nqaij ntawm ib tus neeg, kev sunbathing tsis tu ncua ua rau muaj kev pheej hmoo ntawm cov kab mob oncological;
- UV tawg tsis zoo cuam tshuam rau lub qhov muag ntawm lub qhov muag;
- cov nroj tsuag nyob rau qhov tsis raug rau ultraviolet hluav taws xob tig daj thiab tsis tiav;
- vim yog kis tau ntev mus rau hluav taws xob ultraviolet, yas, roj hmab, ntaub, ntawv dawb lias ntawv siv tsis tau.
Nws tsis yog qhov xav tsis thoob uas tib neeg xav tiv thaiv lawv tus kheej thiab lawv cov khoom kom ntau li ntau tau los ntawm qhov cuam tshuam tsis zoo. Thawj cov khoom polycarbonate tsis muaj peev xwm tiv taus qhov cuam tshuam ntawm tshav ntuj. Yog li ntawd, tom qab 2-3 xyoos ntawm kev siv lawv hauv thaj chaw tshav ntuj (tsev cog khoom, tsev cog khoom, gazebos), lawv yuav luag tag nrho lawv cov peev txheej qub.
Txawm li cas los xij, cov neeg tsim khoom niaj hnub no ntawm cov khoom siv tau saib xyuas kev ua kom hnav tsis kam ntawm cov yas polymer . Txog qhov no, cov khoom lag luam polycarbonate tau pleev xim nrog txheej tshwj xeeb tiv thaiv uas muaj cov tshuaj tshwj xeeb ruaj khov - tiv thaiv UV. Ua tsaug rau qhov no, cov ntaub ntawv tau txais lub peev xwm los tiv thaiv qhov tsis zoo ntawm UV hluav taws xob rau lub sijhawm ntev yam tsis tau poob nws thawj cov txiaj ntsig zoo thiab yam ntxwv.
Kev ua tau zoo ntawm txheej txheej txheej txheej, uas yog ib txoj hauv kev tiv thaiv cov khoom siv los ntawm hluav taws xob thaum lub sijhawm lav kev pab lub neej, nyob ntawm qhov siab ntawm cov tshuaj ntxiv.
Dab tsi yog hluav taws xob tiv thaiv polycarbonate?
Hauv cov txheej txheem tshawb fawb cov ntaub ntawv, cov tuam ntxhab hloov pauv thev naus laus zis ntawm kev tiv thaiv los ntawm lub hnub raug mob. Thaum xub thawj, cov kua roj vanish tau siv rau qhov no, uas muaj tus lej tsis zoo: nws tawg sai, ua huab, thiab tau faib tsis sib luag ntawm daim ntawv. Ua tsaug rau kev txhim kho ntawm cov kws tshawb fawb, thev naus laus zis tshiab ntawm kev tiv thaiv hluav taws xob ultraviolet siv cov txheej txheem sib txuas ua ke tau tsim.
Cov neeg tsim khoom ntawm polycarbonate nrog tiv thaiv UV tsim ntau hom khoom, uas txawv ntawm qhov hnav tsis kam thiab, raws li, tus nqi.
Kev tiv thaiv UV tuaj yeem siv rau daim hlau polymer hauv ntau txoj hauv kev
- Txau . Txoj hauv kev no suav nrog siv cov yeeb yaj kiab tiv thaiv tshwj xeeb rau cov yas yas, uas zoo ib yam li cov xim pleev xim. Vim li ntawd, polycarbonate tau txais lub peev xwm los cuam tshuam feem ntau ntawm cov duab hluav taws xob ultraviolet. Txawm li cas los xij, cov khoom siv no muaj qhov tsis zoo: txheej tiv thaiv tuaj yeem ua puas yooj yim thaum thauj mus los lossis teeb tsa. Thiab tseem nws yog tus yam ntxwv tsis muaj zog tiv taus huab cua nag lossis daus. Vim tias cuam tshuam rau polycarbonate ntawm cov xwm txheej tsis zoo saum toj no, txheej tiv thaiv raug tshem tawm, thiab cov khoom ua rau muaj kev phom sij rau UV tawg. Lub neej kwv yees kwv yees yog 5-10 xyoo.
- Extrusion . Qhov no yog txheej txheem nyuaj thiab kim rau cov chaw tsim khoom, uas suav nrog kev cog cov txheej tiv thaiv ncaj qha mus rau hauv cov polycarbonate nto. Xws li daim ntaub thaiv yuav tiv taus txhua yam kev nyuab siab thiab qhov tshwm sim ntawm huab cua. Txhawm rau ua kom zoo dua qub, qee cov tuam ntxhab thov siv 2 txheej txheej tiv thaiv rau polycarbonate, uas ua rau txhim kho qhov khoom tau zoo. Cov chaw tsim khoom muab lub sijhawm lav thaum lub sijhawm cov khoom yuav tsis poob nws cov khoom. Raws li txoj cai, nws muaj hnub nyoog 20-30 xyoo.
Qhov ntau ntawm cov ntawv polycarbonate yog qhov dav: lawv tuaj yeem ua pob tshab, xim, tinted, nrog cov nplaim paj. Kev xaiv cov khoom lag luam tshwj xeeb yog nyob ntawm ntau qhov xwm txheej, tshwj xeeb, ntawm thaj chaw npog, nws lub hom phiaj, tus neeg yuav khoom pob nyiaj siv thiab lwm yam. Cov qib kev tiv thaiv ntawm cov yas polymer yog pov thawj los ntawm daim ntawv pov thawj tias tus xa khoom ntawm cov khoom yuav tsum muab rau tus neeg siv khoom.
Daim ntawv thov thaj tsam
Canvases ua los ntawm cov yas yas nrog tiv thaiv UV tau siv hauv ntau thaj chaw ntawm kev tsim kho
- Txhawm rau npog gazebos, tsev noj mov nyob ruaj ruaj thiab cov khw noj mov qhib . Tib neeg, rooj tog thiab ntau yam khoom siv hauv tsev tuaj yeem nyob hauv qab qhov chaw tiv thaiv los ntawm kev tiv thaiv polycarbonate ntev.
- Rau kev tsim cov ru tsev ntawm cov qauv loj: cov chaw nres tsheb ciav hlau, tshav dav hlau . Cov ntaub ntawv muaj zog thiab ntseeg tau yuav ua rau tib neeg nyob hauv nws kom xis nyob thiab nyab xeeb li sai tau.
- Rau cov tuam tsev raws caij nyoog: pavilions, stalls, sheds over the shopping arcade . Rau canopies hla lub qhov rooj nkag thiab lub qhov rooj, cov phaj polymer zoo tib yam tau xaiv ntau dua - cov khoom lag luam nrog cov tuab 4 hli yuav tiv thaiv los ntawm huab cua phem thiab tib lub sijhawm yuav muaj txiaj ntsig ntau dua thiab pheej yig dua plexiglass lossis cov ntaub thaiv npog.
- Rau cov tsev ua liaj ua teb: tsev cog khoom, tsev cog khoom lossis tsev cog khoom . Nws tsis tsim nyog cais cov nroj tsuag los ntawm hluav taws xob UV vim qhov tseeb tias lawv tau koom nrog hauv kev cog ntoo cog paj ntoo. Yog li ntawd, qib kev tiv thaiv ntawm cov phaj polymer uas tau siv rau lub hom phiaj no yuav tsum muaj tsawg.
Cov neeg nyob hauv lub caij ntuj sov thiab cov neeg tsim khoom tau nce pib siv cov yas yas, uas tiv thaiv UV hluav taws xob, uas qhia nws qhov kev ua tau zoo. Cov ntaub pua plag polycarbonate ruaj khov, hnyav, nyab xeeb thiab muaj qhov zoo nkauj zoo nkauj.
Cov ntaub ntawv raug xaiv raug yuav pab tsis tsuas yog khaws cov cuab yeej, tab sis kuj ua rau tus neeg nyob hauv nws yooj yim li sai tau.
