HDPE dej yeeb nkab nyob qhov twg?
Vim nws qhov tshwj xeeb zoo,HDPE yeeb nkab dejyog dav siv nyob rau hauv engineering siv dej mov yeeb nkab, faus cov kav dej, engineering siv central cua sov, roj pipeline, vuam thiab kev sib txuas lus cov cuab yeej tu waterproof lub tes tsho, industrial qib pipeline, ua liaj ua teb thiab tsiaj nyeg pipeline, thiab lwm yam Nws yog tsuas yog siv nyob rau hauv lub hwj chim mov, ntuj. roj thiab kev ua liaj ua teb dej hauv nroog loj.Cov khoom tensile zoo heev ua rau cov khoom siv ntau dua.Cov khoom tensile ntawm PE cov yeeb nkab dej yuav qhia kom ntxaws hauv qab no.
Hauv HDPE cov kav dej siv cov kav dej, cov khoom siv polymer muaj lub cev tsim nyog.Cov khoom siv lub cev ntawm cov polymers feem ntau zoo dua rau cov khoom tensile ntawm lwm cov khoom siv HDPE.Ntau tus neeg siv khoom ntseeg tias thaum siv HDPE cov khoom siv los ua cov kav dej, peb tsis quav ntsej txog cov khoom tensile raws li qhov ntsuas kev ua tau zoo, tab sis thaum siv cov khoom siv raw, peb xav tau cov khoom ntawm cov khoom siv polymer.
Feem ntau, muaj cov cua sov shrinkable films thiab shrinkable films, uas yuav tsum tau siab dua tensile zog ntawm raw cov ntaub ntawv.Qhov tseeb, cov khoom siv HDPE tshwj xeeb feem ntau muaj cov khoom tensile ntawm ib ncig ntawm 200%.Raws li nrog HDPE rub accessory daim ntawv thov, qhov kev txheeb xyuas no zoo tagnrho thiab cov khoom tensile zoo kawg nkaus.Vim yog overstretch, HDPE dej muab yeeb nkab accessory nplhaib hlau tsis muaj qhov tsis ntseeg.
HDPE ua lub luag haujlwm li cas hauv cov khoom tensile ntawm cov kav dej?
Thaum cov polymers siv los ua cov ntaub ntawv, ntau tus neeg siv khoom tsis txaus siab rau cov khoom siv kho tshuab.Nyob rau hauv feem ntau cov kev siv ntawm polymers, txhua yam khoom yog arguably tseem ceeb tshaj li lwm yam khoom ntawm lub cev.Ntawm tag nrho cov ntaub ntawv paub, polymers muaj qhov dav tshaj plaws ntawm cov khoom siv kho tshuab.Qhov no yog vim macromolecules yog tsim los ntawm cov saw ntev molecules nrog rau qhov tseem ceeb molecular motion relaxation zog.Thaum cov polymer elongation siab, qhov tawg elongation ntawm PE zoo tib yam yog 90% mus rau 950% (linear low density polyethylene LLDPE muaj ntau dua elongation).Los ntawm cov txheej txheem tsim khoom tshwj xeeb, tus nqi tensile ntev ntawm qee cov ntaub ntawv tuaj yeem yog ntau dua 1000%, thiab qhov elongation ntawm kev tawg ntawm cov khoom siv polymer tuaj yeem ncav cuag 50% -10%.Feem ntau hais lus, tshav kub shrinkable zaj duab xis, tensile zaj duab xis, thiab lwm yam, lub tensile zog ntawm cov khoom yuav tsum siab dua.
HDPE dej xa dej yeeb nkab tensile kev ua tau zoo, tsis yooj yim rau kev puas tsuaj, kev pab lub neej ntev.Tshwj xeeb tshaj yog tsim rau kev siv dej.Kev saib xyuas yog nqa tawm thaum siv los txuas lub sijhawm siv.
