ʻO ka mīkini hana ʻeke he mīkini no ka hana ʻana i nā ʻeke plastik a i ʻole ʻeke mea ʻē aʻe. ʻO kāna ʻano hana ʻo ia nā ʻano plastik a i ʻole nā ​​​​ʻeke mea ʻē aʻe me nā ʻano nui, mānoanoa a me nā kikoʻī. ʻO ka ʻōlelo maʻamau, ʻo nā ʻeke plastik nā huahana nui.

Mīkini hana ʻeke ʻeke

1. Hoʻohui a me ka hoʻohana ʻana i nā ʻeke plastik

1. Nā ʻano ʻeke plastik
(1) Puke kiʻekiʻe polyethylene ʻeke plastik
(2) ʻeke plastik polyethylene haʻahaʻa haʻahaʻa
(3) ʻeke plastik polypropylene
(4) ʻeke plastik PVC

2. Ka hoʻohana ʻana i nā ʻeke plastik

(1) Ke kumu o ka ʻeke plastik polyethylene kiʻekiʻe:
A. Hoʻopili meaʻai: nā keke, ka lole, nā mea palai, nā kuki, ka pauka waiu, ka paʻakai, ke kī, a pēlā aku;
B. ʻO ka pulupulu pulupulu: nā pālule, nā lole, nā huahana pulupulu nila, nā huahana fiber kemikala;
C. Packaging o nā huahana kemika i kēlā me kēia lā.
(2) Ke kumu o ka ʻeke plastik polyethylene haʻahaʻa haʻahaʻa:
A. ʻeke ʻōpala a me ka ʻeke kānana;
B. ʻeke ʻoluʻolu, ʻeke kūʻai, ʻeke lima, ʻeke ʻeke;
C. ʻeke mālama hou;
D. ʻeke ʻeke ʻeke i loko
(3) Ka hoʻohana ʻana i ka ʻeke plastik polypropylene: hoʻohana nui ʻia no ka hoʻopili ʻana i nā textiles, nā huahana pulupulu, nā lole, nā pālule, etc.
(4) Hoʻohana i nā ʻeke plastik PVC: A. ʻeke makana; B. ʻeke ʻeke ukana, ʻeke ʻeke pulupulu mea kūʻai aku, ʻeke ʻeke hoʻonaninani;

C. (zipper) ʻeke palapala a me ka ʻeke ʻikepili.

2.Composition o ka plastics

ʻO ka plastic a mākou e hoʻohana mau ai, ʻaʻole ia he mea maʻemaʻe. Hana ʻia ia me nā mea he nui. I waena o lākou, ʻo ka polymer molecular kiʻekiʻe (a i ʻole synthetic resin) ka mea nui o nā plastics. Eia kekahi, i mea e hoʻomaikaʻi ai i ka hana o nā plastics, pono e hoʻohui i nā mea kōkua like ʻole, e like me nā mea hoʻopihapiha, plasticizer, lubricants, stabilizers a me nā kala, i lilo i plastics me ka hana maikaʻi.

1. ʻO ka resin synthetic
ʻO ka resin synthetic ka mea nui o nā plastics, a ʻo kāna ʻike i loko o nā plastics he 40% ~ 100%. Ma muli o kona kiʻekiʻe kiʻekiʻe a me ke ʻano o ka resin e hoʻoholo pinepine i ke ʻano o nā plastics, manaʻo pinepine ka poʻe i ka resin ma ke ʻano he synonym no nā plastics. No ka laʻana, huikau ka PVC resin a me PVC plastic, phenolic resin a me phenolic plastic. ʻO ka ʻoiaʻiʻo, ʻelua mau manaʻo like ʻole ka resin a me ka plastic. ʻO Resin kahi polymer kumu i hana ʻole ʻia. ʻAʻole i hoʻohana wale ʻia e hana i nā plastics, akā hoʻohana ʻia hoʻi e like me nā mea maka no ka uhi ʻana, nā adhesives a me nā fiber synthetic. Ma waho aʻe o kahi hapa liʻiliʻi o nā plastics i loaʻa ka 100% resin, pono ka hapa nui o nā plastics e hoʻohui i nā mea ʻē aʻe i hoʻohui ʻia i ka resin mea nui.

2. Hoopiha
Hiki i nā mea hoʻopihapiha, i ʻike ʻia he hoʻopihapiha, hiki ke hoʻomaikaʻi i ka ikaika a me ke kūpaʻa wela o nā plastics a hoʻemi i nā kumukūʻai. No ka laʻana, hiki i ka hoʻohui ʻana o ka pauka lāʻau i ka resin phenolic ke hoʻemi nui i ke kumukūʻai, hana i ka plastic phenolic kekahi o nā plastics cheapest, a hoʻomaikaʻi nui i ka ikaika mechanical. Hiki ke hoʻokaʻawale ʻia nā mea hoʻopihapiha i nā mea hoʻopihapiha organik a me nā mea hoʻopiha inorganic, nā mea mua e like me ka pauka lāʻau, nā lole lole, ka pepa a me nā ʻano lole lole like ʻole, a me nā mea hope e like me ke aniani fiber, diatomite, asbestos, carbon black, etc.

3. Mea hoʻopalapala
Hiki i nā plasticizers ke hoʻonui i ka plasticity a me ka palupalu o nā plastics, e hōʻemi i ka brittleness a me ka maʻalahi o ka hana ʻana a me ke ʻano. ʻO ka plasticizer ka mea maʻamau i nā mea hoʻoheheʻe e hoʻolapalapa ʻia me ka resin, ʻaʻohe mea ʻawaʻawa, ʻala ʻole a kūpaʻa i ka māmā a me ka wela. ʻO Phthalates ka mea maʻamau i hoʻohana ʻia. No ka laʻana, i ka hana ʻana i nā plastik PVC, inā hoʻohui ʻia nā plasticizers hou, hiki ke loaʻa nā plastic PVC palupalu. Inā ʻaʻole i hoʻohui ʻia nā plasticizers a liʻiliʻi paha (dosage <10%), hiki ke loaʻa i nā plastik PVC paʻa.

4. Mea hoʻopaʻa
No ka pale ʻana i ka resin synthetic mai ka decomposed a hōʻino ʻia e ka māmā a me ka wela i ke kaʻina hana a me ka hoʻohana ʻana, a hoʻolōʻihi i ke ola lawelawe, pono e hoʻohui ʻia kahi stabilizer i ka plastic. ʻO ka mea maʻamau ka stearate, epoxy resin, etc.

5. Mea kala
Hiki i nā kala kala ke hana i nā plastic i nā waihoʻoluʻu nani a nani. Hoʻohana mau ʻia nā mea waihoʻoluʻu a me nā puaʻa inorganic ma ke ʻano he kala.

6. Lubricant
ʻO ka hana o ka lubricant ka pale ʻana i ka plastik mai ka pipili ʻana i ka ʻeleʻele metala i ka wā e hoʻoheheʻe ʻia, a e hoʻomaʻamaʻa a nani hoʻi ka ʻili plastik. ʻO nā lubricants maʻamau ka stearic acid a me kāna mau paʻakai magnesium calcium.

Ma kahi o nā mea hoʻohui i luna, hiki ke hoʻohui ʻia nā mea pale ahi, nā mea hoʻoulu a me nā mea antistatic i nā plastics e hoʻokō i nā koi noi like ʻole.

Mīkini hana ʻeke lole

ʻO ka ʻeke lole e pili ana i kahi ʻeke i hana ʻia me ke kiʻi ʻoniʻoni OPP a i ʻole PE, PP a me CPP kiʻiʻoniʻoni, ʻaʻohe kiʻi paʻa i ka puka komo a hoʻopaʻa ʻia ma nā ʻaoʻao ʻelua.

Ke kumu:

Hoʻohana nui ʻia mākou no ka hoʻopaʻa ʻana i nā lole kauwela, e like me nā pālule, nā pālule, nā pālule, nā ʻōpala, nā kāwele, ka berena a me nā ʻeke mea nani. ʻO ka mea maʻamau, loaʻa i kēia ʻano ʻeke kahi paʻa ponoʻī iā ia, hiki ke hoʻopaʻa pono ʻia ma hope o ka hoʻouka ʻana i ka huahana. Ma ka mākeke kūloko, kaulana loa kēia ʻano ʻeke a pili nui. Ma muli o kona ʻike maopopo ʻana, he koho maikaʻi nō hoʻi ia no nā makana hōʻailona.
