Ua ʻike anei ʻoe i kahi huinakolu ma lalo o ka ipu plastik?He aha nā helu like ʻole o ka huinakolu?E alakaʻi ʻo LGLPAK.LTD iā ʻoe e hoʻomaopopo i ke ʻano o nā helu.
Aia nā helu 1-7 i loko o ka huinakolu ma lalo o ka ipu plastik, e hōʻike ana i nā mea plastik like ʻole, a ʻo kēia mau code mea plastic kahi kumu nui no kona palekana.
1-PET PET omole
Hana ʻia ia me ka polyethylene terephthalate, ʻaʻohe mea ʻawaʻawa, maikaʻi ka paʻa ʻana o ka ea, ʻaʻole ia e hana i nā flocs.Ma hope o ka hana hou ʻana, lilo ia i mea lua me nā pōmaikaʻi waiwai, no ka mea, ʻoi aku ka nui o ka hoʻohana ʻana., Hāʻawiʻia nā mea lua ma ka home a ma waho, a laweʻia hoʻi i ka'āina nui o Kina, hiki ke hoʻohanaʻia e like me nā fibers non-woven, zippers, filling materials, etc.
2-HDPE kiʻekiʻe kiʻekiʻe polyethylene
ʻO ka pauka keʻokeʻo a i ʻole ka huahana granular, ʻaʻohe mea ʻawaʻawa a me ka ʻono ʻole, ʻo ka crystallinity he 80% ~ 90%, kahi palupalu he 125～l 35℃, hiki i ka mahana o ka lawelawe ke hiki i 100℃, ʻoi aku ka ikaika o ka polyethylene haʻahaʻa haʻahaʻa, ʻeke ʻeke mea maʻamau.
3-PVC polyvinyl chloride
I kēia manawa, ʻo ia ka lua o ka huahana plastik nui loa ma ka honua ma hope o ka polyethylene.Loaʻa iā ia kahi ʻano amorphous o ka pauka keʻokeʻo, me kahi liʻiliʻi liʻiliʻi o ka lālā, kahi pili pili ma kahi o 1.4, kahi mahana hoʻololi aniani o 77 ~ 90 ° C, a me kahi decomposition ma kahi o 170 ° C.He ʻino kona kūpaʻa wela a hoʻoheheʻe ʻia e hana i ka hydrogen chloride ma nā mahana ma luna o 100°C a i ʻole ka ʻike ʻana o ka lā.
4-LDPE polyethylene haʻahaʻa haʻahaʻa
ʻO ia ka mea i hoʻohana nui ʻia i loko o ka ʻeke plastik a me ka ʻoihana paʻi ma nā ʻāina like ʻole.Hoʻohana ʻia ia i loko o kahi kiʻiʻoniʻoni tubular e ke ʻano hoʻoheheʻe ʻana a kūpono ia no ka hoʻopili ʻana i ka meaʻai, ka hoʻopili kemika i kēlā me kēia lā, ka pahu huahana fiber, a me nā mea ʻē aʻe.Inā ʻōwili ʻia ka meaʻai i ka ʻili plastik a wela, e hoʻoheheʻe ia i nā mea ʻino.
5-PP polypropylene
ʻOi aku ka maikaʻi o kona ikaika mechanical, ka ikaika peʻa, ka ea, a me ka pale maʻamau ma mua o ke kiʻi ʻoniʻoni maʻamau.No ka mea, ʻoi aku ka maikaʻi o kēia kiʻiʻoniʻoni plastik, ʻo ka waihoʻoluʻu i hana ʻia ma hope o ka paʻi ʻana he nani loa a nani hoʻi, a he mea koʻikoʻi ia no ka hoʻopaʻa ʻana i ka plastic composite flexible packaging.He kūpaʻa ia i ka corrosion e nā waikawa, alkalis, nā paʻakai paʻakai a me nā ʻano mea hoʻoheheʻe kūlohelohe ma lalo o 80 ℃, a hiki ke decompose ma lalo o ke kiʻekiʻe kiʻekiʻe a me ka oxidation.
6-PS polystyrene
ʻO nā mea i hoʻohana ʻia no ka hana ʻana i nā pahu noodle hikiwawe ahiahi a me nā pahu meaʻai wikiwiki ke kūpaʻa maikaʻi i ka wela, akā ʻaʻole hiki ke waiho ʻia i loko o ka umu microwave.E hoʻokuʻu ka wela kiʻekiʻe i nā kemika ʻona.Hiki i nā ʻakika ikaika a me nā alkalis ke hoʻoheheʻe i ka polystyrene i mea pōʻino i ke kino o ke kanaka.E akahele i ka hoʻohana ʻana.
7-PC polycarbonate a me nā mea ʻē aʻe
ʻO ka PC kahi mea i hoʻohana nuiʻia, hoʻohana nuiʻia i ka hanaʻana i nā'ōmole pēpē, nā kīʻaha ākea, a me nā mea'ē aʻe.No laila, mai hoʻohana i ka ʻōmole PC no ka hoʻopaʻa ʻana i ka wai wela a ʻaʻole hoʻi e hōʻike i ka lā.
Manaʻo wau ua maopopo i nā mea a pau ke ʻano o nā helu.Hiki iā ʻoe ke noʻonoʻo hou aku iā ia i kou ola a hoʻāʻo e pale i nā mea ʻino i kou kino.E lawe ʻo LGLPAK.LTD iā ʻoe e hoʻomaopopo i ka ʻoihana plastik mai kahi hiʻohiʻona ʻoihana.
