Iyini i-Polypropylene Fabric?
Indwangu ye-polypropylene yigama elisetshenziselwa ukuchaza noma yimuphi umkhiqizo wendwangu osuselwe ku-thermoplastic polymer polypropylene. Lolu hlobo lwepulasitiki luyingxenye yeqembu le-polyolefin, futhi aluyona i-polar futhi i-crystalline ingxenye. Eduze kwe-polyethylene, i-polypropylene iwupulasitiki wesibili ovame ukukhiqizwa emhlabeni, futhi isetshenziswa kakhulu ekupakishweni, utshani, nezinye izinhlobo zezimpahla ezithengwayo nezimboni kunezokukhiqiza izindwangu.
Lolu hlobo lwepulasitiki ekuqaleni lwasungulwa yinhlangano yaseMelika iPhillips Petroleum ngo-1951. Osokhemisi uRobert Banks no-J. Paul Hogan babezama ukuthola uphethiloli ku-propylene, futhi benza i-polypropylene ngephutha. Nakuba lokhu kuhlolwa kuthathwe njengokungaphumeleli, kwasheshe kwaqashelwa ukuthi le nhlanganisela entsha inamandla okuba ilingane ne-polyethylene ezinhlelweni eziningi.
Kwaze kwafika ngo-1957, nokho, lapho i-polypropylene yenziwa into efanelekile ukukhiqizwa ngobuningi. Ngo-1954, usokhemisi wase-Italy u-Giulio Natta kanye nozakwabo waseJalimane baphumelela ukwenza le nto ibe i-polymer ye-isotactic, futhi inhlangano yase-Italy i-Montecatini yaqala ngokushesha ukukhiqiza le nto ukuze isetshenziswe futhi isetshenziswe abathengi.
I-Polypropylene ekuqaleni yayimakethwa ngaphansi kwegama elithi “Moplen,” futhi leli gama lisewuphawu lokuthengisa olubhalisiwe lwenhlangano ye-LyondellBasell. Nokho, kuvame kakhulu ukuthola le nto ebizwa ngokuthi i-polypropylene noma “i-polypro” ngamafuphi.
Isihlalo sedekhi esinokhanopi nesihlilingi ngendwangu ye-polypropylene empunga yejuba
Njengoba ukusetshenziswa kwe-polypropylene kuya ngokuya kuthandwa kakhulu kubasebenzisi abaningi kanye nezicelo zezimboni, kancane kancane kwatholakala ukuthi lolu hlobo lwepulasitiki lubonisa amandla njengendwangu. Indwangu ye-polypropylene iyindwangu engalukiwe, okusho ukuthi yenziwe ngokuqondile ngempahla ngaphandle kwesidingo sokuphotha kokuluka. Inzuzo eyinhloko ye-polypropylene njengendwangu yikhono layo lokudlulisa umswakama; le ndwangu ayikwazi ukumunca noma yikuphi umswakama, futhi esikhundleni salokho, umswakama udlula indwangu ye-polypropylene ngokuphelele.
Lesi sici sivumela umswakama okhishwayo ngenkathi ugqoke ingubo ye-polypropylene ukuba uhwamuke ngokushesha kakhulu kunengubo egcina umswakama. Ngakho-ke, le ndwangu idumile ezindwangu ezigqoke eduze kwesikhumba. Nokho, i-polypro inomkhuba wokumunca nokugcina iphunga lomzimba lapho isetshenziselwa izingubo zangaphansi, futhi iphinde incibilike emazingeni okushisa aphansi kakhulu. Indwangu ye-polypro encibilikisiwe ingabangela ukushisa okukhulu, futhi le nkinga yenza kube nzima ukugeza le ndwangu emazingeni okushisa aphezulu.
Indwangu ye-polypropylene ingenye yemicu yokwenziwa elula kunazo zonke ekhona, futhi imelana ngendlela emangalisayo kuma-acid amaningi nama-alkali. Ngaphezu kwalokho, i-thermal conductivity yale nto iphansi kunaleyo yezintambo eziningi zokwenziwa, okusho ukuthi ifaneleka kahle ukugqoka isimo sezulu esibandayo.

Ngaphezu kwalokho, le ndwangu imelana kakhulu nemihuzuko, futhi imelana nezinambuzane nezinye izinambuzane. Ngenxa yezimfanelo zayo eziphawulekayo ze-thermoplastic, kulula ukubumba ipulasitiki ye-polypro ibe yizimo namafomu ahlukahlukene, futhi ingashintshwa ngokuncibilika. Le plastiki nayo ayithinteki kakhulu ekuqhekekeni kwengcindezi.
Kodwa-ke, i-polypro idume kanzima ukudaya ngemuva kokwakhiwa, futhi kunzima nokubumba le ndwangu ibe yizinto ezahlukahlukene. Le ndwangu isengozini yokulimala kwe-UV, futhi ayibambeleli kahle ku-latex noma i-epoxies. Njengazo zonke ezinye izindwangu zokwenziwa, indwangu ye-polypropylene nayo inomthelela omubi kakhulu emvelweni.
Yenziwa Kanjani Indwangu Ye-Polypropylene?
Njengezinhlobo eziningi zamapulasitiki, i-polypro yenziwe ngezinto ezitholakala kumafutha e-hydrocarbon njengowoyela we-petroleum. Okokuqala, i-monomer propylene ikhishwa kuwoyela ongahluziwe ngendlela yegesi, bese le monoma ibe sengaphansi kwenqubo ebizwa ngokuthi i-chain-growth polymerization ukuze kwakhiwe i-polymer polypropylene.
Uma inani elikhulu lama-propylene monomers selihlanganiswe ndawonye, kwakheka impahla yepulasitiki eqinile. Ukuze wenze indwangu esebenzisekayo, i-polypropylene resin kufanele ixutshwe nezinhlobonhlobo zamapulasitiki, iziqinisi, nezigcwalisi. Lezi zithasiselo zingeniswa ku-polypro encibilikisiwe, futhi uma into oyifunayo isitholiwe, le pulasitiki ingase ivunyelwe ukupholisa ibe izitini noma ama-pellets.
Lawa ma-pellets noma izitini abe esedluliselwa embonini yendwangu, futhi ayancibilika. Ezimweni eziningi, le polypropylene ibe isibunjwa ibe amashidi, noma ingase ivunyelwe ukupholisa ezibunjeni. Uma amashidi enziwe, le micu emincane ibe isisikwa ibe yisimo oyifunayo bese ithungwa noma inamathiselwe ukuze kwakhiwe izingubo noma amanabukeni. Kusetshenziswa izindlela ezahlukahlukene zokukhiqiza ukwenza i-polypropylene ibe yimikhiqizo engagqoki.
Isetshenziswa Kanjani Indwangu Ye-Polypropylene?
Indwangu ye-Polypro ivame ukusetshenziswa ezimpahleni zokugqoka lapho kufunwa ukudluliswa komswakama. Isibonelo, lolu hlobo lwepulasitiki luvame ukusetshenziselwa ukwenza amashidi aphezulu amanabukeni, okuyizingxenye zamanabukeni athintana ngqo nesikhumba. Ngokusebenzisa i-polypropylene yale ngxenye ye-diaper, kuyaqinisekiswa ukuthi akukho umswakama ozohlala uthintana nesikhumba somntwana, okunciphisa amathuba okuba ama-rashes akheke.
Le ndwangu engalukiwe yokudlulisa umswakama nayo iyenze yaba yindwangu ethandwayo yegiya lesimo sezulu esibandayo. Isibonelo, lokhu kokwenziwa kwakusetshenziselwa ukwenza izingubo zangaphansi nezikhindi zangaphansi ezasetshenziswa esizukulwaneni sokuqala se-US Army's Extended Cold Weather Clothing System (ECWCS). Kwatholakala ukuthi izingubo ezenziwe ngale ndwangu zathuthukisa ukunethezeka kwamasosha esimweni sezulu esibandayo, kodwa izinkinga ngezindwangu ze-polypro ziye zabangela ukuthi amasosha ase-United States ashintshele esizukulwaneni sakamuva sendwangu ye-polyester yezinhlelo zabo zeGeneration II kanye neGeneration III ECWCS.
Kwezinye izimo, indwangu ye-polypropylene ingase isetshenziselwe ukwenza izingubo zezemidlalo, kodwa izinkinga ezimbalwa ngalolu hlobo lwepulasitiki zenze izinguqulo ezintsha ze-polyester zithandwa kakhulu kulolu hlelo lokusebenza. Nakuba izici zokudlulisa umswakama zale ndwangu zifiseleka kakhulu ezimpahleni zemidlalo, ukungakwazi ukugeza le ndwangu ngamanzi ashisayo kwenza kube nzima ukususa iphunga elivela ku-polypropylene sportswear. Ngaphezu kwalokho, ukuthambekela kwale ndwangu ekulimaleni kwe-UV kuyenza ibe ukukhetha okungalungile kunoma yiluphi uhlobo lwezingubo zangaphandle.
Ngale kwezwe lezingubo, ipulasitiki ye-polypropylene isetshenziswa ezinkulungwaneni zezicelo ezahlukahlukene. Okunye okudume kakhulu ukusetshenziswa kwalesi sithako ukuphuzwa ngotshani; kuyilapho utshani benziwe ngephepha ekuqaleni, i-polypropylene manje isiyinto ekhethwayo yalolu hlelo lokusebenza. Lo pulasitiki usetshenziselwa nokwenza izintambo, amalebula okudla, ukupakisha ukudla, izibuko zelanga, kanye nezinhlobonhlobo zezinhlobo zezikhwama.
Ikhiqizwa kuphi Indwangu yePolypropylene?
I-China njengamanje ingumthengisi omkhulu kakhulu wemikhiqizo ye-polypropylene. Ngo-2016, amafekthri kuleli zwe akhiqize ivolumu yamapulasitiki e-polypro enenani lama-dollar ayizigidi eziyizinkulungwane ezingu-5.9, futhi kulinganiselwa ukuthi lo mzila uzohlala uzinzile esikhathini esizayo esibonakalayo.
Inqwaba yale nto yenziwa eJalimane; leli zwe likhiqize cishe amabhiliyoni angu-2.5 we-polypropylene ngo-2016, kanti i-Italy, i-France, i-Mexico, ne-Belgium nazo zingabakhiqizi ababalulekile bale nto. Ngo-2016, i-United States yakhiqiza i-$ 1.1 billion emikhiqizweni ye-polypro.
Umdlali omkhulu embonini yamazwe ngamazwe yokukhiqiza i-polypropylene yiLyondellBasell. Le nkampani ifakwe eNetherlands, futhi inezisekelo zokusebenza eHouston naseLondon.
Iqembu eliphume isibili kulo mkhakha yiSinopec Group, eseBeijing, kanye nePetroChina Group, nayo ezinze eBeijing. Abakhiqizi abaphezulu abayi-10 balesi sidakamizwa benza amaphesenti angama-55 okukhiqizwa okuphelele kwe-polypropylene emhlabeni jikelele.
I-Polypropylene icutshungulwa ibe yindwangu emhlabeni wonke. Umkhiqizi omkhulu wezindwangu eziqediwe ze-polypro yiShayina, futhi lolu hlobo lwendwangu luphinde luthungelwe ezingutsheni nezinye izinhlobo zezindwangu eNdiya, ePakistan, e-Indonesia nakwamanye amazwe amaningana.
Ibiza Malini Indwangu Ye-Polypropylene?
