HDPE yog ib qho thermoplastic polyolefin uas yog los ntawm ethylene copolymer. Txawm hais tias HDPE twb pib nyob rau xyoo 1956, lub hnab yas tsis tau txog nws cov theem paub tab. Cov ntsiab lus tseem ceeb no tseem tsim los tsim nws cov kev siv tshiab thiab kev lag luam. Ib thermoplastic cob. Cov tsos ntawm cov haiv neeg HDPE yog cov xim dawb thiab yog luv luv nyob hauv qhov nqaim nqaim. PE muaj cov khoom zoo heev uas tiv taus ntau lub neej thiab muaj tshuaj. Qee hom tshuaj tsim cov tshuaj lom neeg muaj zog, xws li cov kab coustic oxidants (concentrated nitric acid), cov ntxhuav roj (xylene), thiab hydrogen carbon (halogenated hydrocarbons) (carbon tetrachloride). Lub polymer tsis nqus noo thiab muaj kev tiv thaiv zoo
PE tuaj yeem tsim nyob rau hauv ntau hom kev sib txawv. Xws li ntawv extrusion, zaj duab xis extrusion, yeeb nkab lossis profile extrusion, tshuab molding, txhaj tshuaj molding thiab yas.
HDPE raj
HDPE yeeb nkab yog ib yam khoom tshiab ntawm cov yeeb nkab cov yeeb nkab thiab polyvinyl chloride haus dej yeeb nkab.
HDPE yeeb nkab yuav tsum dais ib lub siab, feem ntau yog xaiv ib lub cev loj loj thiab muaj cov khoom zoo ntawm cov khoom PE, xws li cov HDPE reag. LDPE rein muaj lub zog tsis muaj zog, muaj zog tsis kam, tsis rigidity, tsis ruaj ntseg stability thaum lub caij sib tw thiab tsis yooj yim txuas. Nws tsis tsim nyog siv los ua khoom siv rau cov dej haus yeeb nkab. Tab sis vim nws txoj kev ntsuas siab siab, LDPE, tshwj xeeb tshaj yog LLDPE cob, tau dhau los ua ib qho khoom siv los tsim cov kav dej. Lub viscosity ntawm LDPE thiab LLDPE cob yog me me, lub flowability zoo thiab qhov ua yog yooj yim, yog li qhov ntau ntawm lawv cov melt Performance Index yog dav, thiab MI yog feem ntau ntawm 0.3-3g / 10min.
