Ntau cov khoom lag luam txhua hnub zoo li daim npog kho mob txhua hnub, ntaub so ntswg, thiab lwm yam, muaj qhov tsis muaj kev ywj pheej ntawm kev tswj hwm qhov zoo ntawm ntau cov ntsiab lus me me. Cov qauv no kom tau txais cov neeg siv khoom tuaj yeem tau txais cov khoom lag luam nrog kev txaus siab, thiab cov tuam ntxhab yuav tsum tau txhim kho lawv cov txheej txheem thiab kev ua tau zoo tsis tu ncua. Tus qauv xeem yuav hloov kho raws ntau txhiab tus ntawv ceeb toom thiab cov neeg siv khoom 'tom qab muag cov lus qhia.
Hais txog tus PE Sarp lossis Vinyl Tarp xeem, muaj ntau cov kev ntsuam xyuas xws li xim xim, muaj ntau yam khoom siv ua ntej, Kuv yuav qhia cov txheej txheem ant-resistant qhov tseem ceeb.
Dab tsi yog cov ntsiab lus tseem ceeb ntawm cov polyethylene lossis ntaub vab tshayl UV tiv taus?
● Kev siv hluav taws xob
Qhov ntau ntawm UV hluav taws xob muaj ntau, ntawm <0.1nm rau> 1mm. Lub hnub ci ultra-kev ua phem yog ntawm 300 tawm ntev ntev rau peb cov tawv nqaij, tab sis cuam tshuam rau ntau cov tawv nqaij 'kev ua kom muaj ntau cov tawv nqaij zoo li cov polyethylene lossis vinyl.
PE TARP tuaj yeem siv rau 1-2 xyoos. Tab sis qhov tseeb, ib puag ncig nrog ntau qhov kev laus uas muaj ntau yam kev laus tuaj yeem txo cov kav lub neej ntawm tarps. Ua ntej UV kuaj, tus kws tshaj lij yuav teeb tsa ntau txoj kev ib puag ncig zoo li nag, av noo, thiab lwm yam kev sib cais los simulate cov txheej txheem laus hauv lub tshuab. Qib irradiance yuav yog 0.8-1.0 w / ㎡ / nm, zoo ib yam li lub hnub ci tiag.
● LAMB hom & thov
Fluorescent ulaviolet teeb tuaj yeem thov rau ASTM G154 xeem. Vim muaj ntau hom ntawm cov khoom tsis yog hlau, cov kev qhia tshwj xeeb ntawm cov teeb yuav txawv. Tus thib 3 saib xyuas kev ib puag ncig yuav kos cov ntsiab lus ntawm lub teeb hauv daim ntawv qhia.
Lub chaw kuaj kub sab hauv tsev & kev nrug deb kuj tseem yuav cuam tshuam txog qhov ntsuas hluav taws xob tiag tiag los ntawm cov qauv ntaub. Yog li qhov kawg hluav taws xob ntsuas hluav taws xob yuav xa mus rau cov ntes tshwj xeeb.
Yuav ua li cas mus ua UV kev kuaj mob
Thaum xub thawj, cov qauv ntaub yuav raug txiav los ntawm 75x150mm lossis 75 x300mm thiab tom qab ntawd kho nrog Aluminium Voj. Tso cov qauv rau hauv QUV xeem Chamber thiab teeb txhua yam tsis muaj.
0, 100, 300, 500, 750, 1000, 1500, 2000 teev tuaj yeem txhawb nqa. Cov QV xeem Chamber muaj lub zog ua si nrawm nrog 4 x 6 x ... Yog tias qhov parameter yog 85 teev tiag tiag los txhawb qhov raug ntawm lub ntuj 1000 teev.
Hais txog PE lossis Vinyl tarp, nws yog txaus rau cov qauv kom tau txais 300-500 stimululated teev 'kis tau. Tom qab ntawd, cov kuaj sim yuav pib ntsuas hauv qab no, xws li xim xim, kua muag yeem, dej tsis kam, dej tsis kam, dej tsis kam. Piv nrog cov qauv qub, daim ntawv tshaj tawm zaum kawg yuav raug sau tseg.
