Dab tsi yog qhov txawv ntawm PE cov kav dej thiab PE roj yeeb nkab

PE cov yeeb nkab dej thiab PE roj yeeb nkab yog ob hom PE kav dej, tab sis ntau tus neeg siv muaj kev nkag siab zoo txog lawv txoj kev siv thiab tsis paub meej txog kev paub qhov txawv ntawm lawv li cas. Txhawm rau pab txhawb cov neeg siv kev siv thiab xaiv zoo dua, peb yuav nkag siab thiab nkag siab lawv los ntawm ntau yam.
1. Kev tshwm sim:
Txhawm rau paub qhov txawv ntawm PE cov kav dej thiab cov kav dej PE, ua ntej saib xyuas cov kav dej. Nws tuaj yeem pom tseeb tias muaj plaub kab xiav nyob rau saum npoo ntawm cov kav dej, thiab qee cov tuam ntxhab yuav tsim cov kav dej dawb lossis lwm yam xim, tab sis lawv tag nrho nrog cov kab xiav; Nyob rau saum npoo ntawm cov yeeb nkab roj, muaj ib txoj kab txiv kab ntxwv lossis daj, yog li lawv tuaj yeem txawv ntawm sab nraud.

2. Daim ntawv thov:
Kuj tseem muaj qhov sib txawv tseem ceeb hauv daim ntawv thov, vim tias ob qho tib si PE cov kav dej thiab cov kav dej PE yog ua los ntawm polyethylene. Tam sim no, polyethylene tau muab faib ua tsib qib: PE32, PE40, PE80, PE100, thiab PE63. Cov qib PE100 thiab PE8O feem ntau yog siv rau cov kav dej PE thiab cov kav dej PE. Yav dhau los, tsis muaj kev faib tawm rau cov ntaub ntawv polyethylene hauv Suav teb, uas ua rau ntau lub tuam txhab muaj teeb meem tshwj xeeb hauv kev xaiv cov khoom siv dej thiab cov kav dej, thiab tseem muaj qee qhov kev phom sij zais.
3. Muaj cov kev hloov pauv tseem ceeb hauv cov qauv, nrog rau qib sib txawv ntawm PE100 thiab PE80 muaj qhov sib txawv compressive zog, ua rau muaj zog compressive zog. Nyob rau tib lub sijhawm, lub zog tensile zog hauv cov qauv qub tau raug tshem tawm, yog li ua kom lub elongation ntawm kev tawg (ntau dua 350 feem pua) thiab ntxiv dag zog rau qhov yooj yim toughness ntawm cov khoom.
Los ntawm kev nkag siab saum toj no, nws tuaj yeem pom tias qhov sib txawv ntawm PE cov kav dej thiab cov kav dej PE yog qhov yooj yim heev, tab sis lawv cov kab zoo li tuaj yeem siv los ua qhov txawv ntawm lawv zoo dua.
