Yabụ, kedu uru na njirimara nke iji polylactic acid anaghị kpara akwa dị ka iheihe nzacha ikuku?
Biodegradability
Maka ihe nzacha nkpuchi, biodegradability bụ njirimara dị oke mkpa. Ihe nzacha ihe nkpuchi ọdịnala na-eji akwa agbaze okpukpu abụọ gbazere PP anaghị kpara akpa, nke fọrọ nke nta ka ọ bụrụ ihe na-emebi emebi. Ihe mkpuchi ndị a gbahapụrụ agbahapụ, ma ọ bụ na-asọba n'osimiri na oke osimiri ma ọ bụ nke e liri n'ala, na-etinye nnukwu ihe egwu na gburugburu ebe obibi.
Ihe mkpuchi nzacha oyi akwa merepolylactic acid iheọ bụghị naanị na-enyocha ihe ndị na-emerụ ahụ nke ọma dị ka uzuzu na nje bacteria na ikuku, kamakwa ọ na-eweda ala mgbe ejiri ya na mkpofu, na-ebelata nrụgide na gburugburu ebe obibi.
Mgbe ngwaahịa fiber polylactic acid ekpughere na gburugburu eke nwere ụfọdụ okpomọkụ na iru mmiri (dịka ájá, silt, mmiri oké osimiri), polylactic acid nwere ike mebie kpamkpam n'ime carbon dioxide na mmiri site na microorganisms. Ọ bụrụ na a na-eli eriri polylactic acid n'ime ala, oge mmebi eke bụ ihe dị ka afọ 2-3; Ọ bụrụ na agwakọta eriri polylactic acid na ihe mkpofu organic wee lie ha, ha ga-ere ere n'ime ọnwa ole na ole.
Enwere ike imebi ngwaahịa polylactic acid kpamkpam ka ọ bụrụ carbon dioxide na mmiri n'okpuru ọnọdụ composting nke ụlọ ọrụ (okpomọkụ 58 ℃, iru mmiri 98% na ọnọdụ microbial) maka ọnwa 3-6.
Antibacterial na deodorizing ihe
Ihe dị iche iche nke eriri polylactic acid dabere na ikike ya ọ bụghị naanị nweta "nyocha anụ ahụ", kamakwa "nyocha ndụ".

N'ihe gbasara deodorization, ọ na-adabere na acidity nke ya iji mebie nhazi cell nke isi na-akpata nje bacteria, gbuo isi na-akpata nje bacteria, ma nweta mmetụta nke deodorization.
Dabere na njirimara a, polylactic acid nwere ike iwepu ihe mkpuchi biodegradable nwere mmetụta deodorizing dị ukwuu na enwere ike eyi ya ogologo oge na-enweghị iku ume.
