Dab tsi yog kev pab cuam lub neej ntawm luv luv fiber ntau geotextile?
Cov tib neeg yeej ib txwm nyiam tshawb nrhiav cov hauv kev ntawm lub sijhawm ntev tiv thaiv UV thiab HDPE geomembrane tiv thaiv, vim hais tias ntawm lub ntuj laus ntawm luv luv fiber geotextile. Feem ntau, lub cev kev laus dhau los thiab cov khoom hloov ntawm lub neej-lub sij hawm tshwm sim los ntawm lwm qhov chaw ib puag ncig yog txhua qhov hu ua kev laus. Cov kev hloov pauv ntawm cov khoom siv tuaj yeem raug txiav txim los ntawm kev tshawb nrhiav cov tshuab yam ntxwv hloov ntawm cov khoom. Qee qhov xwm txheej, peb tuaj yeem kwv yees cov khoom siv lub neej ntev los ntawm kev hloov pauv ntawm cov khoom ntiag tug.
Luv luv luv geotextile yog tsim los ntawm cov qib siab zoo polyethylene cob. Txhawm rau tiv thaiv kev laus los ntawm Ultraviolet teeb, peb ntxiv 2% -3% hmoov carbon dawb dub rau hauv cov khoom siv. Cov pa roj carbon dub tuaj yeem tiv thaiv kom tsis txhob muaj cov cuab yeej los ntawm kev laus dhau los ua kom zoo txog li 50years. High-density polyethylene muaj kev ruaj khov ua hauj lwm ntawm anti-ultraviolet lub teeb thiab cua sov nyob rau hauv anaerobic tej yam kev mob. Lub tshuab nruab nrab ntawm cov polyethylene niaj zaus saw saw sib cais thiab sib xyaw ua ke thiab cov cuam tshuam ntawm lub cev hloov thaum lub sij hawm tshav kub poob, Molecular saw tawg txoj kev puas tsuaj tsuas yog tshwm sim ntawm qhov kub siab tshaj 350 ° C, Kev hloov kho cov khoom yog ethylene, propylene, butene thiab ntev dua olefin tawg nrog cov roj molecular. Tsis tsuas yog qhov zoo ntawm cov tshuaj pleev ib qho tseem ceeb xwb, tab sis polyethylene resin nws tus kheej kuj tseem yog qhov tseem ceeb hauv UV tsis kam. Ntau yam ntawm cov khoom ntawm cov tuaj yeem kho kom nws muaj peev xwm tiv taus UV hluav taws xob. Tam sim no nws tau pom tias txo qis ntawm qhov ceev ntawm polyethylene puag resin txo qhov kev laus thiab tshuaj lom neeg tiv thaiv ntawm cov resin thaum tseem txo cov kev cuam tshuam ntawm cov tshuaj stabilizers thiab carbon dub.
