Kedu ihe dị iche n'etiti akpa nri na akpa rọba nkịtị?

1. Polyethylene: Isi ihe dị na ya bụ polyethylene resin, na-agbakwunye obere mmanụ mmanu, onye na-eme agadi na ihe mgbakwunye ndị ọzọ.Polyethylene bụ ihe na-esi ísì ụtọ, nke na-adịghị egbu egbu, na-acha ọcha na-acha ọcha.A na-ekewa HDPE n'ime polyethylene dị elu, polyethylene dị obere na obere njupụta polyethylene dị ka morphology, ọdịnaya na usoro nhazi nke polymer.
A na-akpọkarị plastik polyethylene dị ka nrụgide ala HDPE.E jiri ya tụnyere polyethylene dị ala na LLDPE, plastik polyethylene nwere nguzogide okpomọkụ dị elu, nguzogide abrasion, mmiri vapor hydrophilicity na nrụgide mgbawa na gburugburu ebe obibi.Na mgbakwunye, plastik polyethylene nwere ike dielectric magburu onwe ya, nguzogide mmetụta na nguzogide oyi.Ọ dabara maka ngwaahịa oghere (dị ka karama iko, karama mmiri), ịkpụzi injection, ịkpụzi injection na ụlọ ọrụ ndị ọzọ.
Polyethylene dị ala dị ala (LINEARLOWDENSYPOYETHYLENE, LLDPE) bụ polymer mepụtara site na polymerization nke ethylene na obere obere olefins dị elu n'ihu onye na-eme ihe.Ọdịdị ya dị ka nke polyethylene dị ala, ma gloss elu ya dị mma, na obere okpomọkụ elongation na elu Modulus, na-ehulata na-eguzogide, iguzogide ala nrụgide cracking, ala okpomọkụ mmetụta compressive ike na ndị ọzọ uru.
A na-ejikarị ya maka ịkpụzi injection, extrusion, ịfụ ụfụ na ụzọ ịkpụzi ihe ndị ọzọ iji mepụta fim, ihe ndị dị mkpa kwa ụbọchị, ọkpọkọ, wires na eriri.
2. Polypropylene: Akụkụ bụ isi bụ polypropylene resin, nke nwere nnukwu gloss na nnyefe ọkụ.Ọrụ mkpuchi okpomọkụ dị njọ karịa PE, mana ọ dị mma karịa ihe ndị ọzọ plastik.
1. Ọrụ mgbochi dị mma karịa PE, ike ya, ike ya na isi ike dị mma karịa PE;
2. Ahụike na nchekwa dị elu karịa egwuregwu
3. Ọ nwere ezigbo okpomọkụ na-eguzogide ma nwee ike iji ya mee ihe ruo ogologo oge na okpomọkụ nke 100 degrees Celsius, ma oyi oyi na-eguzogide na-eme ka arụmọrụ nke HDPE dịkwuo mma ma ghọọ ihe na-egbuke egbuke na -17 degrees Celsius.
Akpa nkwakọ ngwaahịa nke ihe nkiri plastik dị elu karịa platinum, ihe ndị na-emepụta ihe na-egbuke egbuke na ihe ndị na-adịghị akwa akwa n'ihe banyere nkwụsị nke iyi na mmiri na-eguzogide, ma mmetụta mbipụta akwụkwọ na-adịghị mma na ọnụ ahịa dị ala.Enwere ike iji ya maka nkwakọghachi azụ nke lollipops na nri nri.Enwere ike ime ya ka ọ bụrụ ihe nkiri nkwakọ ngwaahịa okpomọkụ na-ebelata ihe oriri, dị ka nri na nri plastik akpa akpa na akpa nkwakọ ngwaahịa ndị ọzọ mejupụtara.
3. Polystyrene: A polymer na styrene monomer dị ka isi akụrụngwa.Ihe a na-egbuke egbuke ma na-egbuke egbuke.
1. Mgbochi mmiri dị njọ karịa PE, nkwụsi ike nke kemịkal bụ n'ozuzu, ike siri ike dị elu, ma brittleness dị ukwuu.
2. Ezi obere okpomọkụ na-eguzogide, ma ogbenye elu okpomọkụ eguzogide, enweghị ike gafere 60≤80 ℃.
3. Ezi ihe nchekwa.
