ʻO ke kaula polymer polyethylene kiʻekiʻe i hana ʻia me ka polymer polyethylene fiber kiʻekiʻe kiʻekiʻe loa i ka fiber synthetic, hiki i kona ikaika ke hiki i 1.5 mau manawa o ka uea kila kikoʻī like, a haʻahaʻa loa ka elongation, hiki ke hoʻohālikelike ʻia me ka lōʻihi haʻihaʻi o ke kila kila. uea.ʻO ke kaula i hanaʻia mai ia mea he mau hiʻohiʻona o ke kū'ēʻana o ka radiation ultraviolet, ke kū'ēʻana o ke kai, kaʻakika a me ka alkali, ke kūpaʻa luhi, ke aniau a me ka likeʻole o ka mahana, ka lōʻihi o ka lawelaweʻana, etc.

He aha ka polyethylene?

ʻO ka pōkole o ka polyethylene PE, ʻo PE ka polyethylene abbreviation, ʻo ia ka polyethylene [-CH2-CH2-] N. ʻO ka ethylene he polymer o ka ethylene, he resin thermoplastic hoʻi, i ka ʻoihana, ethylene a me kahi mea liʻiliʻi o ka α-olefin copolymerization nā huahana. Loaʻa iā ia nāʻano o ka meaʻawaʻawaʻole, kaʻalaʻole, ka paʻi a me ka lama kukui ua aneane likeʻole.

ʻO ka PE (polyethylene) kahi mea maʻamau, hoʻohana maʻamau mākou i ka ʻeke ola ʻoluʻolu i hana ʻia me ka polyethylene (PE), he mea maʻalahi loa ka PE o ka polymer, ua hoʻohana nui ʻia nā mea, ua haku ʻia he helu o - CH2 - ʻāpana. nā loulou, ʻo ka polyethylene ma o ka ethylene (CH2=CH2) hoʻohui polymerization reaction.

PE(polyethylene) i ka hana paʻa kemika o a, hoʻokahi, hydrochloric acid, hydrofluoric acid, formic acid, phosphoric acid, potassium hydroxide, a me nā ʻakika ʻē aʻe a me nā kumu he mea kōkua ʻole i ka lumi wela. ʻO ke kukui ultraviolet he mea maʻalahi loa ka decompose, he mea kōkua nui ia i ka hoʻohaʻahaʻa ʻana i nā ʻeke plastik.

E hoʻohana: PE (polyethylene) hana ʻano hana kiʻekiʻe kiʻekiʻe, ʻano kaomi maʻamau a me ke ʻano haʻahaʻa haʻahaʻa ʻekolu, hiki ke hoʻohana ʻia ke kuleana o ka mea PE no ka hana kiʻiʻoniʻoni, hoʻohana nui ʻia i ka meaʻai, ka lāʻau lapaʻau, ka mea hoʻomomona a me ka ʻoihana. e hana i nā lako mīkini, ka hana ʻana i nā mea pāpaʻi paipu, hiki i ka PE ke hana i ka fiber, ke kaula polyethylene a me nā lako ola ʻē aʻe.
