HDPE bụ abbreviation nke elu njupụta polyethylene, nke bụ a thermoplastic polyolefin kpụrụ site copolymerization nke ethylene.HDPE bụ opaque ọcha waxy ihe onwunwe.Nnukwu ike ndọda ya dị mfe karịa mmiri, dị nro ma sie ike, mana ọ siri ike karịa LDPE.
Ọ dịkwa ntakịrị na-agbanwe, anaghị egbu egbu na enweghị ụtọ.Ọ bụ ngwaahịa nke polymerization n'okpuru ọnọdụ nrụgide dị ala catalyzed site na Ziegler catalyst, ya mere a na-akpọkwa polyethylene dị elu dị elu. nkesa, na mgbakwunye.A na-eji ihe dị iche iche eme ihe iji mepụta polymer pụrụ iche omenala.Ụdị mgbanwe ndị a na-ejikọta iji mepụta akara ule HDPE maka ojiji dị iche iche;
Uru nke HDPE:
1. HDPE nwere ezigbo nguzogide ọtụtụ kemịkalụ ụlọ na ụlọ ọrụ.Ọ na-eguzogide corrosion na mgbasa site na oxidants siri ike, acid-base salts and organic solvents.
2. HDPE bụ onye na-abụghị hygroscopic ma nwee ezigbo ihe mgbochi mmiri na steaming.Enwere ike iji ya mee ihe ngosi mmiri, mgbochi seepage ma ọ bụ nkwakọ ngwaahịa.

3. HDPE nwere ezigbo ọkụ eletrik, karịsịa ike dielectric dị elu, na-eme ka ọ dị mma maka waya na eriri.Ọkara na ogo molekụla dị elu nwere ezigbo nguzogide mmetụta, ma na ọnọdụ okpomọkụ yana ọbụlagodi na obere okpomọkụ nke -40F.
4. HDPE nwere ezigbo nhazi na ikpo ọkụ ọkụ.
5. HDPE nwere ọkwa dị elu nke akwụkwọ, isi ike na oghere, ike siri ike bụ 4 ruo 5 ugboro nke ihe nkiri LDPE.Ike elu ya, ike nkwụsịtụ, ike siri ike na ike ndị ọzọ na-arụ ọrụ dị nso na PP, nke siri ike karịa PP.
6. HDPE adịghị egbu egbu na enweghị isi, a pụkwara iji ya mee ihe maka nri, uwe, knitwear na ihe nkwakọ ngwaahịa ndị ọzọ, akụ na ụba.
Ọdịmma nke HDPE:
1. Mmegide ya ịka nká na nrụgide gburugburu ebe obibi adịghị mma dị ka LDPE, karịsịa thermal oxidation ga-ebelata ọrụ ya.Ya mere, a na-agbakwunye polyethylene dị elu na mgbochi-oxidant na UV absorber iji mee ka ọ ghara ezuru mgbe a na-eme ya ka ọ bụrụ eriri plastik.Ebee.
2. HDPE nwere obere nghọta na ihe mgbochi na-adịghị mma maka ikuku oxygen na gas ndị ọzọ.
3. siri ike ibipụta, mgbe a na-ebipụta akwụkwọ, a na-achọ ọgwụgwọ nkwụsị elu, enweghị ike ịmegharị ya, elu ahụ na-agwụ ike.
