Ib tus kav dej zoo yuav tsum tsis txhob tsuas muaj kev lag luam zoo nkaus xwb, tab sis kuj muaj qhov zoo xws li kev ruaj khov thiab txhim khu kev qha, los tiv thaiv cov khoom siv, kev tiv thaiv, kev laus ua hauj lwm thiab kev ua kom tsis muaj zog. HDPE yeeb nkab yeeb nkab yog ib qho khoom siv hluavtaws nrog cov additives ua los ntawm melting thiab molding. Cov khoom siv no muaj xws li: plasticizers, stabilizers, fillers, lubricants, colourants, ultraviolet absorption agents, modifiers, thiab lwm yam. HDPE yeeb nkab yog siv rau: municipal engineering dej khoom, tsev dej hauv tsev tu dej, sab nrauv faus dej thiab lub thaj chaw, thaj chaw ntawm qhov faus dej, qhov kho qhov qub qub, kho dej thiab kho dej, lub vaj tsev botanical, kev ywg dej thiab lwm qhov chaw ntawm cov kav dej thiab lwm yam. Sib piv nrog cov tshuaj yeeb nkab, wei lub hnub qub Hdpe yeeb nkab muaj cov nram qab no: 1. Cov kev txuas yog txhim khu kev ruaj ntseg, polyethylene yeeb nkab uas siv hluav taws xob kub ntu kev sib txuas nruab nrab ntawm, lub zog ntawm kev sib koom tes yog siab dua lub zog ntawm cov yeeb nkab lub cev. 2. Kev ua kom tsis muaj qhov kub ntxhov: Cov tshuaj polyethylene uas tsis tshua muaj siab kub hnyiab tau tsawg kawg, tuaj yeem siv tau 60-60 ℃ ntawm qhov ntsuas kub kom zoo. Thaum lub sij hawm lub caij ntuj no kev tsim kho, vim hais tias ntawm qhov zoo kuj tsis kam ntawm cov khoom, lub yeeb nkab yuav tsis keej. 3. Zoo tiv thaiv kev nyuab siab: HDPE muaj tsawg tshaj thais kev rhiab heev, siab tsho lub zog thiab zoo ua haujlwm rau khawb, thiab ib puag ncig kev ntxhov siab yog qhov tseem ceeb heev. 4. Kev quav tshuaj tiv thaiv zoo: lub raj xa hluav taws xob HDPE muaj peev xwm tiv tau qhov corrosion ntawm ntau yam tshuaj tawm, thiab cov tshuaj muaj nyob rau hauv cov av yuav tsis ua teeb meem ntawm cov yeeb nkab. Polyethylene yog ib qho hluav taws xob insulator, yog li yuav tsis muaj lwj, xeb lossis electrochemical corrosion; Tsis yog nws txhawb kev loj hlob ntawm algae, kab mob los yog fungi. 5. Kev laus ua haujlwm thiab lub neej ntev kev ua haujlwm: 2-2.5% tus qauv roj carbon polyethylene yeeb nkab tuaj yeem khaws cia rau hauv cov cua qhib rau 50 xyoo thiab yuav tsis ua puas los ntawm ultraviolet hluav taws xob.
Nyob hauv thaj teb ntawm cov av nkos, HDPE yog sib piv nrog cov yeeb nkab.
Lub raj xa dej tau zoo dua coj los ua haujlwm, uas txhais tau hais tias HDPE pipeline muaj kev pab cuam lub neej thiab kev ua lag luam zoo dua.
