Khoom siv:
PP cov ntaub ntawv yog ua los ntawm propylene monomer polymerization, muaj ib tug siab ntawm crystallinity, yog li nws muaj ib tug siab hardness thiab rigidity.
Cov khoom siv PE yog tsim los ntawm ethylene monomer polymerization, muab faib ua high density polyethylene (HDPE) thiab low density polyethylene (LDPE) thiab lwm yam sib txawv, nrog rau kev ua haujlwm siab thiab ductility.
Lub cev muaj zog:
PP cov ntaub ntawv feem ntau muaj qhov kub thiab txias ntau dua li cov ntaub ntawv PE, yog li lawv tuaj yeem tiv taus qhov kub siab dua.
PE cov khoom muaj qhov zoo toughness thiab txias tsis kam, haum rau qhov kub thiab txias ib puag ncig.
Chemical Properties:
PP cov ntaub ntawv feem ntau muaj qhov zoo corrosion kuj nyob rau hauv qhov kev txiav txim ntawm cov tshuaj thiab cov kuab tshuaj, thiab yuav siv tau stably nyob rau hauv ntau chemical ib puag ncig.
PE cov ntaub ntawv tuaj yeem nkag siab rau qee yam tshuaj, thiab kev ruaj ntseg ntawm ntau hom PE rau cov khoom siv tshuaj kuj txawv.
Daim ntawv thov teb:
Cov khoom siv PP feem ntau yog siv los ua cov thawv ntim khoom, cov kav dej, cov khoom siv hauv tsheb, cov khoom siv hauv tsev, qhov cub thiab lwm yam khoom uas yuav tsum tau ua kom muaj zog thiab thermal stability.
PE cov khoom siv feem ntau yog siv los ua cov thawv insulated, hnab yas, fwj, xaim thiab cable rwb thaiv tsev thiab lwm yam khoom uas xav tau kev hloov pauv thiab txias.
Summary ntawm qhov zoo thiab qhov tsis zoo:
Qhov zoo ntawm cov khoom PP:
Zoo rigidity thiab hardness.
Zoo tiv taus kub thiab tshuaj lom neeg corrosion.
Haum rau cov ntawv thov uas xav tau cov cuab yeej siv siab thiab thermal stability.
Disadvantages ntawm PP khoom:
Cov tawv nqaij tawv, tsis yoog raws li cov khoom PE.
Tej zaum yuav ua nkig ntawm qhov kub thiab txias.
Qhov zoo ntawm cov khoom siv PE:
Zoo elasticity thiab ductility.
Zoo txias tsis kam, tseem yoog raws nyob rau hauv qhov kub thiab txias ib puag ncig.
Qhov zoo tshaj plaws rau cov ntawv thov uas xav tau kev tiv thaiv txias thiab kev sib cais.
Qhov tsis zoo ntawm cov khoom siv PE:
Feem ntau yog mos, tsis nruj li PP khoom.
Tej zaum yuav ua mos los yog deformed ntawm qhov kub thiab txias.
Tej zaum yuav rhiab rau tej yam tshuaj.
Kev xaiv ntawm PP lossis PE cov khoom yuav tsum tau txiav txim siab raws li cov kev xav tau tshwj xeeb, xav txog kev ua haujlwm, ib puag ncig, tus nqi thiab lwm yam uas yuav tsum tau ua los ntawm cov khoom.
Yog tias koj tsis kam yuav cov khoom siv twgkhau npog, koj tuaj yeem nyeem tsab xov xwm no los pab koj txiav txim siab zoo.
