Abstract: Tsab xov xwm no qhia txog cov ntsiab lus tseem ceeb ntawm cov txheej txheem ntawm kev siv acov khoom sib xyaw uas tsis muaj kuab tshuajlub hnab yas aluminium kub siab, thiab taw qhia txog qhov zoo ntawm cov khoom sib xyaw uas tsis muaj kuab tshuaj.
Cov txheej txheem tsis muaj kuab tshuaj ua ke ntau yam zoo xws li kev tiv thaiv ib puag ncig thiab tus nqi, thiab maj mam hloov cov khoom sib xyaw qhuav hauv ntau qhov chaw siv. Txawm li cas los xij, ntau lub tuam txhab tsis kam sim cov khoom ua noj kub siab, tshwj xeeb tshaj yog cov uas muaj cov qauv ntawv ci txhuas. Vim tias ntau tus neeg txhawj xeeb txog kev pheej hmoo ntawm kev siv cov khoom sib xyaw tsis muaj kuab tshuaj: lawv puas tuaj yeem tiv taus kev ua noj kub siab? Puas yog nws yuav raug txheej? Lub zog tev tawv yog dab tsi? Puas yuav attenuation sai dhau? Nws ruaj khov npaum li cas?
Cov no yog cov ntsiab lus tseem ceeb ntawm kev siv cov khoom siv kub siab uas tsis muaj kuab tshuaj sib xyaw ua ke, thiab tsab xov xwm no yuav tshawb nrhiav cov teeb meem no ib qho zuj zus.
1,Cov qauv dav dav thiab cov qauv kev tsim nyog rau cov khoom ua noj kub siab
Tam sim no, raws li tus neeg siv xav tau, hom ntsiab lus, thiab cov qauv ncig, cov qauv khoom ntawm cov hnab ua noj kub siab feem ntau muab faib ua peb pawg: ob txheej membrane, peb txheej membrane, thiab plaub txheej membrane qauv. Ob txheej membrane qauv feem ntau yog BOPA/RCPP, PET/RCPP; Peb txheej membrane qauv yog PET/AL/RCPP, BOPA/AL/RCPP; Plaub txheej membrane qauv yog PET/BOPA/AL/RCPP lossis PET/AL/BOPA/RCPP.
Peb paub cov qauv ntawm lub hnab ua noj, peb yuav soj ntsuam li cas seb lub hnab ua noj puas tsim nyog?
Los ntawm qhov kev xav tau ntawm kev lag luam thiab cov khoom ntim khoom, feem ntau nws raug txiav txim siab los ntawm cov hauv qab no:
1.1 、 Kev ua noj ua haus tsis kam: feem ntau yog hais txog ntau qib kev ua noj tsis kam, xws li npau ntawm 100 ° C, 121 ° C, thiab ua noj kub ntawm 135 ° C rau 30-40 feeb. Txawm li cas los xij, kuj tseem muaj qee cov chaw tsim khoom uas xav tau lwm qhov kub;
1.2, Lub zog tev tawv yog dab tsi;
1.3 、 Kev tiv thaiv kev laus; Feem ntau, qhov kev sim no ua nyob rau hauv qhov cub 60 ° C lossis 80 ° C, thiab lub zog tev tawv raug ntsuas tom qab 7 hnub ntawm kev ziab
1.4, Tam sim no, muaj ntau yam khoom siv rau cov neeg siv khoom uas tsis tas yuav ua noj, tab sis lub tuam txhab xav txog cov ntsiab lus ntawm cov ntsiab lus ntim khoom, xws li 75% cawv ntxuav tes, tshuaj ntxhua khaub ncaws, hnab npog ntsej muag uas muaj cov kua nplaum thiab lwm yam khoom kuj tsim los ntawm cov kua nplaum ua noj kub.
2,Kev sib piv nqi
2.1. Tus nqi ntawmcov khoom sib xyaw uas tsis muaj kuab tshuajyog 0.15 yuan ib square meter tsawg dua li ntawm cov khoom sib xyaw qhuav. Yog tias xam raws li kev tsim khoom txhua xyoo ntawm 10 lab square meters ntawm cov khoom ua noj kub siab los ntawm lub tuam txhab ntim khoom, nws tuaj yeem txuag cov nqi nplaum los ntawm 1.5 lab yuan ib xyoos, uas yog cov nyiaj tau los ntau.
3,Lwm yam zoo
Ntxiv rau tus nqi, cov khoom sib xyaw uas tsis muaj kuab tshuaj kuj muaj cov txiaj ntsig zoo li nram no: Txawm hais tias hais txog VOCs emissions, kev siv hluav taws xob, kev ua haujlwm zoo, lossis kev poob ntau lawm, cov khoom sib xyaw uas tsis muaj kuab tshuaj muaj cov txiaj ntsig zoo, tshwj xeeb tshaj yog nrog kev paub txog ib puag ncig ntawm cov neeg, cov pa phem ntawm cov kuab tshuaj tuaj yeem txo qis.
Xaus lus
Raws li kev tshuaj xyuas saum toj no, cov txheej txheem sab hauv ua noj ua haus kub siab uas tsis muaj kuab tshuaj tuaj yeem ua tau raws li qhov xav tau ntawm feem ntau ntawm cov khoom lag luam hauv kev ua lag luam, thiab zoo dua li cov khoom qhuav hauv kev siv tus nqi, VOC emissions, kev ua haujlwm zoo, thiab lwm yam. Tam sim no, cov khoom siv tsis muaj kuab tshuaj tau raug siv hauv kev ua lag luam hauv xyoo 2013. Raws li cov lus tawm tswv yim ntawm kev ua lag luam hauv 10 xyoo dhau los, nws tau siv dav hauv ntau yam khoom noj braised, khoom noj txom ncauj, tshuaj txhua hnub, thiab ntim khoom hnyav.
