ʻO Cellophane ka mea kahiko loa i hoʻohana ʻia no ka uhi ʻana i nā kuki, nā lole a me nā nati.Ua kūʻai mua ʻia ʻo Cellophane ma ʻAmelika Hui Pū ʻIa i 1924 a ʻo ia ke kiʻi ʻoniʻoni mua i hoʻohana ʻia a hiki i ka makahiki 1960.Ma ka mākeke ʻike kaiapuni i kēia lā, ke hoʻi mai nei ka cellophane.No ka mea he 100% biodegradable ka cellophane, ʻike ʻia ʻo ia he mea ʻoi aku ka maikaʻi o ke kaiapuni i ka hoʻopili ʻana.Loaʻa i ka Cellophane ka helu wai wai awelika a me ka machinability maikaʻi loa a me ka hoʻopaʻa ʻana i ka wela, e hoʻohui ana i kona kaulana i kēia manawa i ka mākeke ʻai meaʻai.
ʻAʻole like me nā polymers i hana ʻia e ke kanaka i loko o nā plastics, ka mea i loaʻa nui mai ka petroleum, cellophane he polymer kūlohelohe i hana ʻia mai cellulose, kahi ʻāpana o nā mea kanu a me nā lāʻau.ʻAʻole hana ʻia ka cellophane mai nā kumu lāʻau ua, akā mai nā kumu lāʻau i ulu a ʻohi ʻia no ka hana cellophane.
Hana ʻia ʻo Cellophane ma ka ʻeli ʻana i ka lāʻau a me ka pulupulu pulp i loko o ke ʻano o nā ʻauʻau kemika e wehe i nā haumia a wāwahi i nā kaulahao loloa i loko o kēia mea maka.Hoʻololi hou ʻia i loko o kahi kiʻiʻoniʻoni ʻoniʻoni me nā kemika plasticizing i hoʻohui ʻia e hoʻomaikaʻi i ka maʻalahi, ʻo ka cellophane ka hapa nui o nā molekole cellulose crystalline.
ʻO ia hoʻi, hiki ke wāwahi ʻia e nā microorganism i loko o ka lepo e like me nā lau a me nā mea kanu.Aia ʻo Cellulose i kahi papa o nā pūhui i loko o ke kemika organik i kapa ʻia ʻo carbohydrates.ʻO ka ʻāpana kumu o ka cellulose ka mole glucose.Hoʻopili pū ʻia nā kaukani o kēia mau molekala glucose i ka wā o ka ulu ʻana o ka mea kanu e hana i nā kaulahao lōʻihi i kapa ʻia he cellulose.ʻO kēia mau kaulahao, ma ka huli ʻana, e wāwahi i ka wā o ka hana ʻana e hana i nā kiʻiʻoniʻoni cellulose i hoʻohana ʻia ma ke ʻano i uhi ʻole ʻia a i uhi ʻia i loko o ka pahu.
Ke kanu ʻia, hoʻohaʻahaʻa pinepine ʻia nā kiʻiʻoniʻoni cellulose uncoated i 10 a 30 mau lā;Ua ʻike ʻia nā kiʻiʻoniʻoni i uhi ʻia e PVDC e hoʻohaʻahaʻa i ka 90 a 120 mau lā, a ua hoʻohaʻahaʻa ʻia ka cellulose i uhi ʻia i ka nitrocellulose i 60 a 90 mau lā.
Ua hōʻike ʻia nā hoʻokolohua ʻo ka awelika o ka manawa e hoʻopau ai i ka biodegradation o nā kiʻiʻoniʻoni cellulose he 28 a 60 mau lā no nā huahana uncoated a me 80 a 120 mau lā no nā huahana cellulose i uhi ʻia.I loko o ka wai loko, he 10 mau lā no ka kiʻiʻoniʻoni uncoated a me 30 lā no ke kiʻi cellulose i uhi ʻia.ʻO nā mea i manaʻo ʻia he degradable loa, e like me ka pepa a me nā lau ʻōmaʻomaʻo, ʻoi aku ka lōʻihi o ka hoʻohaʻahaʻa ʻana ma mua o nā huahana cellulose film.ʻO ka ʻokoʻa, hōʻike liʻiliʻi nā hōʻailona o ka hōʻino ʻana ma hope o ke kanu lōʻihi ʻana i nā plastics, polyvinyl chloride, polyethylene, polyethylene terephthalate a me oriented polypropylene.
Hoʻohana ʻia nā kiʻi ʻoniʻoni cellophane i nā ʻano palapala hoʻopihapiha, me:
- Candy, ʻoi aku ka wili wili
– Lamination pepa
– He hu
– kīʻaha palupalu
- Hoʻopili ʻia ʻo Tampon
- ʻO nā noi ʻoihana like ʻole e like me nā substrate no nā lipine paʻa ponoʻī, nā membrane permeable i nā ʻano semi-kekahi mau ʻano o nā pila, a me nā mea hoʻokuʻu i ka hana ʻana i nā huahana fiberglass a me nā huahana.
