He aha ka Polypropylene Fabric: Nā waiwai, pehea i hana ʻia ai a ma hea
na Sewport Kākoʻo Hui • Mei 25, 2022
He aha ka Polypropylene Fabric?
ʻO ka lole polypropylene kahi huaʻōlelo i hoʻohana ʻia e wehewehe i nā huahana textile i loaʻa mai ka polypropylene polymer thermoplastic. ʻO kēia ʻano plastic kahi ʻāpana o ka hui polyolefin, a he polar ʻole a he ʻāpana crystalline. Ma hope o ka polyethylene, ʻo ka polypropylene ka lua i hana pinepine ʻia ma ka honua, a ʻoi aku ka maʻamau o ka hoʻohana ʻana i ka ʻeke, nā ʻōpala, a me nā ʻano mea kūʻai aku a me nā waiwai ʻoihana ma mua o ka hana textile.
Ua hoʻokumu mua ʻia kēia ʻano plastic e ka hui ʻAmelika ʻo Phillips Petroleum i ka makahiki 1951. Ke hoʻāʻo nei nā mea kemika ʻo Robert Banks lāua ʻo J. Paul Hogan e kiʻi i ka ʻaila mai propylene, a ua hana hewa lākou i ka polypropylene. ʻOiai ua manaʻo ʻia he hemahema kēia hoʻokolohua, ua ʻike koke ʻia he hiki ke hoʻohālikelike ʻia kēia pūhui hou me ka polyethylene i nā noi he nui.
ʻAʻole hiki i ka makahiki 1957, akā naʻe, ua hana ʻia ka polypropylene i mea kūpono no ka hana nui. I ka makahiki 1954, ua lanakila ka Italian chemist ʻo Giulio Natta a me kāna hoa Kelemania i ka hana ʻana i kēia mea i loko o ka polymer isotactic, a ua hoʻomaka koke ka hui Italia ʻo Montecatini e hana i kēia mea no ka hoʻohana ʻana i nā mea kūʻai aku.
Ua kūʻai mua ʻia ka Polypropylene ma lalo o ka inoa ʻo "Moplen," a ʻo kēia inoa kahi inoa inoa inoa inoa o ka hui ʻo LyondellBasell. Eia naʻe, ʻoi aku ka maʻamau o ka loaʻa ʻana o kēia mea i kapa ʻia he polypropylene a i ʻole "polypro" no ka pōkole.
ʻO ka noho deck me ka uhi a me ka maʻa i ka lole polypropylene i ka hina hina
I ka lilo ʻana o ka polypropylene i mea kaulana loa i ka nui o nā mea kūʻai aku a me nā noi ʻoihana, ua ʻike liʻiliʻi ʻia ua hōʻike pū ʻia kēia ʻano plastic i hiki ke ʻano he textile. ʻO ka lole polypropylene kahi lole lole ʻaʻole i ulana ʻia, ʻo ia hoʻi, ua hana pololei ʻia ia mai kahi mea me ka pono ʻole o ka wili o ka ulana. ʻO ka pōmaikaʻi nui o ka polypropylene ma ke ʻano he lole ʻo ia kona hiki ke hoʻololi i ka wai; ʻAʻole hiki i kēia textile ke komo i ka makū, a ma kahi o, hele ka maʻamau i loko o ka lole polypropylene holoʻokoʻa.
Hāʻawi kēia ʻano i ka makū i hoʻokuʻu ʻia i ka wā e ʻaʻahu ana i ka lole polypropylene e hoʻoheheʻe ʻoi aku ka wikiwiki ma mua o ke kapa hoʻopaʻa wai. No laila, kaulana kēia lole i nā lole i hoʻokomo kokoke i ka ʻili. Eia nō naʻe, hiki i ka polypro ke komo a mālama i nā mea ʻala kino ke hoʻohana ʻia no nā ʻaʻahu lalo, a heheʻe nō hoʻi ia i nā haʻahaʻa haʻahaʻa. Hiki i ka lole polypro hoʻoheheʻe ke kumu i ke kuni koʻikoʻi, a hiki ʻole i kēia pilikia ke holoi i kēia lole i nā wela kiʻekiʻe.
ʻO ka lole polypropylene kekahi o nā fiber synthetic māmā loa i ke ola, a he kūpaʻa nui ia i ka hapa nui o nā waikawa a me nā alkalis. Eia kekahi, ʻoi aku ka haʻahaʻa o ka conductivity thermal o kēia mea ma mua o ka hapa nui o nā fibers synthetic, ʻo ia hoʻi, kūpono ia no ka lole anuanu.
Ka lole ʻeke ʻeke a me ke keʻokeʻo i ulana ʻia i ka Polypropylene Upholstery
Eia kekahi, ʻaʻole kūpaʻa loa kēia lole i ka abrasion, a pale pū i nā iniseti a me nā mea ʻino ʻē aʻe. Ma muli o kāna mau ʻano thermoplastic kaulana, maʻalahi ke hoʻoheheʻe i ka plastic polypro i nā ʻano like ʻole a me nā ʻano, a hiki ke hoʻololi ʻia ma o ka hoʻoheheʻe ʻana. ʻAʻole hiki ke maʻalahi kēia plastic i ka pohā koʻikoʻi.
Eia nō naʻe, kaulana ka polypro i ka paʻakikī ke kala ʻia ma hope o ka hana ʻia ʻana, a paʻakikī hoʻi ke hoʻohālikelike ʻana i kēia lole i nā ʻano like ʻole. Hiki ke maʻalahi kēia lole i ka pōʻino o UV, a ʻaʻole ia e pili pono i ka latex a me nā epoxies. E like me nā lole synthetic ʻē aʻe, ʻo ka lole polypropylene kekahi hopena maikaʻi ʻole i ke kaiapuni.
Pehea i hana ʻia ai ka lole polypropylene?
E like me ka hapa nui o nā plastics, hana ʻia ka polypro mai nā mea i loaʻa mai nā wahie hydrocarbon e like me ka aila ʻaila. ʻO ka mua, lawe ʻia ka monomer propylene mai ka ʻaila ʻaila i loko o ke ʻano kinoea, a laila hoʻokomo ʻia kēia monomer i kahi kaʻina i kapa ʻia ʻo chain-growth polymerization e hana i ka polymer polypropylene.
I ka wā e hui pū ʻia ai ka nui o nā monomer propylene, ua hoʻokumu ʻia kahi mea plastik paʻa. No ka hana ʻana i kahi textile hiki ke hoʻohana ʻia, pono e hui pū ʻia ka resin polypropylene me nā ʻano plasticizers, stabilizers, a me nā mea hoʻopihapiha. Hoʻokomo ʻia kēia mau mea hoʻohui i loko o ka polypro i hoʻoheheʻe ʻia, a i ka manawa e loaʻa ai ka mea i makemake ʻia, hiki ke ʻae ʻia kēia plastic i loko o nā pōhaku lepo a i ʻole nā palapala.
Hoʻoili ʻia kēia mau pellets a i ʻole nā pōhaku i kahi hale hana lole, a hoʻoheheʻe ʻia lākou. I ka hapanui o nā hihia, hana ʻia kēia polypropylene i ʻāpana, a i ʻole e ʻae ʻia e hoʻolili i loko o nā mole. Inā hana ʻia nā pepa, ʻokiʻoki ʻia kēia mau ʻili lahilahi i ke ʻano i makemake ʻia a humuhumu ʻia a hoʻopili ʻia e hana i nā lole a i ʻole nā pepe. Hoʻohana ʻia nā ʻano hana hana like ʻole e hana i ka polypropylene i nā huahana ʻaʻahu ʻole.
Pehea e hoʻohana ʻia ai ka lole polypropylene?
Hoʻohana mau ʻia ka lole polypro i nā noi lole kahi e makemake ʻia ai ka hoʻololi ʻana i ka makū. No ka laʻana, hoʻohana mau ʻia kēia ʻano plastic no ka hana ʻana i nā ʻili o luna no nā diapers, ʻo ia nā ʻāpana o nā diapers e pili pono ana i ka ʻili. Ma ka hoʻohana ʻana i ka polypropylene no kēia ʻāpana diaper, ua hōʻoiaʻiʻo ʻia ʻaʻole e mau ka makū e pili ana i ka ʻili o kahi pēpē, e hōʻemi ana i ka hiki ke hoʻokumu ʻia.
ʻO kēia ʻano mea hoʻoneʻe wai ʻole o kēia lole i hoʻolilo ʻia ia i mea lole kaulana no nā mea anu. No ka laʻana, ua hoʻohana ʻia kēia synthetic no ka hana ʻana i nā lole lalo a me nā pālule i hoʻohana ʻia i ka hanauna mua o ka Pūnaehana ʻAi ʻAi Kūlohelohe o ka US Army's Extended Cold Weather Clothing System (ECWCS). Ua ʻike ʻia ʻo nā lole i hana ʻia mai kēia lole i hoʻomaikaʻi i ka hōʻoluʻolu o nā koa i nā kūlana anuanu, akā naʻe nā pilikia me nā lole polypro ua hoʻololi ka pūʻali koa ʻAmelika i ka hanauna hou o nā textiles polyester no kā lākou Generation II a me Generation III ECWCS system.
I kekahi mau hihia, hiki ke hoʻohana ʻia ka lole polypropylene no ka hana ʻana i nā lole haʻuki, akā ua hoʻonui ka nui o nā pilikia me kēia ʻano plastic i nā mana hou o ka polyester no kēia noi. ʻOiai makemake nui ʻia nā waiwai hoʻoili wai o kēia lole no nā lole haʻuki, ʻo ka hiki ʻole ke holoi i kēia lole me ka wai wela e paʻakikī ke wehe i nā ʻala mai nā lole haʻuki polypropylene. Eia kekahi, ʻo ka maʻalahi o kēia textile i ka pōʻino o UV ke koho maikaʻi ʻole ia no nā ʻano lole waho.
Ma waho aʻe o ka honua o ka lole, hoʻohana ʻia ka plastic polypropylene i nā kaukani o nā noi like ʻole. ʻO kekahi o nā mea kaulana loa o kēia mea i loko o ka mauʻu inu; ʻOiai ua hana mua ʻia nā ʻōpala mai ka pepa, ʻo ka polypropylene ka mea i makemake ʻia no kēia noi. Hoʻohana pū ʻia kēia plastic i ka hana ʻana i nā kaula, nā lepili meaʻai, ka ʻeke meaʻai, nā aniani, a me nā ʻano ʻeke like ʻole.
Ma hea i hana ʻia ai ka lole polypropylene?
ʻO Kina ka mea kūʻai nui loa i nā huahana polypropylene i kēia manawa. I ka makahiki 2016, ua hana nā hale hana ma kēia ʻāina i ka nui o nā plastic polypro i kūʻai ʻia ma $5.9 biliona, a ua manaʻo ʻia e paʻa mau kēia alahele no ka wā e hiki mai ana.
He nui no keia mea i hanaia ma Geremania; Ua hana kēia ʻāina ma kahi o $2.5 biliona o ka polypropylene i ka makahiki 2016, a ʻo Italia, Farani, Mekikoka, a me Belgium kekahi mau mea hana nui o kēia mea. Ma 2016, ua hana ʻo ʻAmelika i $ 1.1 biliona i nā huahana polypro.
ʻO ka mea pāʻani nui loa i ka ʻoihana hana polypropylene honua ʻo LyondellBasell. Hoʻohui ʻia kēia hui ma Netherlands, a he mau kumu hana ma Houston a me Lākana.
ʻO ka mea lanakila ma kēia ʻoihana ʻo Sinopec Group, kahi i hoʻokumu ʻia ma Beijing, a me PetroChina Group, aia hoʻi ma Beijing. ʻO nā mea hana 10 kiʻekiʻe o kēia mea waiwai no 55 pakeneka o ka nui o ka hana ʻana o ka polypropylene ma ka honua holoʻokoʻa.
Hoʻopili ʻia ka polypropylene i mau lole a puni ka honua. ʻO Kina ka mea hana nui loa o nā lole polypro, a ua humuhumu ʻia kēia ʻano lole i nā lole a me nā ʻano lole ʻē aʻe ma India, Pakistan, Indonesia, a me nā ʻāina ʻē aʻe.
ʻEhia ke kumu kūʻai o ka lole polypropylene?
Hoʻokomo ʻia ka liner lole polypropylene i loko o kahi moena kedera
No ka mea ʻo polypro kekahi o nā ʻano plastik i hana nui ʻia, ʻoi aku ka maʻalahi o ka nui. He heluna nui o nā hale hana nui like ʻole e hoʻokūkū kekahi i kekahi e hopu i ka mākeke plastik o ka honua, a ʻo kēia hoʻokūkū e hoʻohaʻahaʻa i nā kumukūʻai.
Eia nō naʻe, ʻoi aku ke kumukūʻai o ka lole polypropylene. ʻO ke kumu nui o kēia kumukūʻai hoʻonui ʻia ʻo ka nele o ka noi; ʻOiai ua hoʻohana pinepine ʻia ka lole polypropylene no ka hana ʻana i nā lole lole wela, ʻo ka holomua hou o ka hana ʻana i ka polyester ua lilo kēia ʻano lole i mea kahiko loa. No laila, ʻoi aku ke kumukūʻai o kēia ʻano lole i nā mea hana lole ma mua o nā lole synthetic like, e like me ka polyester, a hāʻawi ʻia kēia kumukūʻai hoʻonui i ka mea kūʻai aku.
He mea nui e akaka, akā, pili wale kēia kumukūʻai i ka lole polypropylene i hoʻolālā ʻia e hana ʻia i ʻaʻahu. Kūʻai ʻia nā ʻano lole polypropylene like ʻole i kūpono i nā lole i nā kumu kūʻai haʻahaʻa, a ʻaʻole i kūʻai ʻia. Hiki mai kēia mau lole i nā ʻano kala like ʻole a me nā ʻano like ʻole.
He aha nā ʻano like ʻole o ka lole polypropylene ma laila?
Hiki ke hoʻohui ʻia nā ʻano mea hoʻohui like ʻole i ka polypro ʻoiai aia i kona ʻano wai e hoʻololi i nā ʻano o kēia mea. Eia kekahi, ʻelua ʻano nui o kēia plastic:
• Homopolymer polypropylene: Ua manaʻo ʻia ʻo Polypro plastic he homopolymer i kona kūlana mua me ka ʻole o nā mea hoʻohui. ʻAʻole manaʻo ʻia kēia ʻano plastic polypro he mea maikaʻi no ka lole.
• Copolymer polypropylene: ʻO ka hapa nui o nā lole polypropylene he copolymer. Hoʻokaʻawale hou ʻia kēia ʻano ʻilika polypro i poloka copolymer polypropylene a me random copolymer polypropylene. Hoʻonohonoho ʻia nā ʻāpana co-monomer i loko o ke ʻano poloka o kēia plastik i nā hiʻohiʻona huinahā maʻamau, akā ua hoʻonohonoho ʻia nā ʻāpana co-monomer ma ke ʻano maʻamau. Ua kūpono nā poloka a i ʻole polypropylene maʻamau no nā noi lole, akā ʻoi aku ka maʻamau o ka polypro plastic block.
