Vim li cas thiaj tsis tuaj yeem siv cov kev ntsuas roj los hloov cov dej siab tom qab kev teeb tsa PE kav dej? Cov ntaub ntawv qhia txog PE yeeb nkab vuam ua haujlwm tuaj yeem tau txais: vuam kub: 220 ° C ± 10 ° C. Yog li ntawd. Lub sij hawm cua sov: yeeb nkab phab ntsa thickness 9-12 vib nas this. Cov khoom tuab, PE yeeb nkab, feem ntau yog siv los ua kom paub qhov txawv ntawm kev siv thiab kev siv tshuab ntawm cov khoom. Cov khoom thickness yuav tsum nyob rau hauv tus txheej txheem ntau yam, thiab tsis muaj qhov sib txawv tseem ceeb nyob rau hauv txawv cross-sectional thickness tests.
Kev ntub dej yuav cuam tshuam rau kev ua haujlwm ntawm cov khoom siv hauv kev tsim cov kav dej PE, yog li cov ntaub ntawv feem ntau qhuav ua ntej siv, uas tuaj yeem txo qee yam uas cuam tshuam rau lawv kev siv thaum lub sij hawm tsim cov PE kav. Raws li kev npaj thiab kev siv cov raj xa dej, yog tias muaj teeb meem nrog kev vuam, muaj peev xwm ua kom muaj dej txaus lossis txawm tias cov yeeb nkab tawg thaum lub sij hawm thauj mus los tom ntej.
PE muaj kev tiv thaiv zoo rau feem ntau ntawm cov tsev neeg thiab cov khoom siv tshuaj. Tsis tas li ntawd, qhov kub tsis tshua muaj kev cuam tshuam ntawm cov kav dej PE yog qhov zoo heev, thiab qhov kub thiab txias ntawm polyethylene tsis tshua muaj, uas tuaj yeem siv tau zoo nyob rau hauv qhov kub ntawm -60-60 degree. Kev sib txuas yooj yim rau cov kav dej PE. Kev siv tseem ceeb ntawm kev sib txuas ntawm kub yaj thiab hluav taws xob yaj txuas rau kev sib txuas ntawm cov kav dej; Thiab nws muaj kev tiv thaiv zoo rau dej rauj siab, welded pob qij txha ua ke nrog PE kav, thiab PE kav dej muaj peev xwm tiv thaiv kev txav hauv av thiab qhov kawg loads.
Cov khoom siv molten siv nyob rau hauv vuam ntawm PE kav yog txias rau ntawm lub puab nto ntawm lub tes tsho sizing, tsim ib txheej ntawm agglomerated nto txheej los xyuas kom meej meej txheej txheej ntawm cov kav dej thiab ruaj khov thiab ib txwm traction thiab extrusion ntawm cov kav dej. Yog li ntawd, cov qauv thiab kev ua kom txias ntawm lub tes tsho sizing.
