Iyini Indwangu Ye-Polypropylene?
Indwangu ye-polypropylene yigama elisetshenziselwa ukuchaza noma yimuphi umkhiqizo wendwangu otholakala ku-polypropylene ye-thermoplastic polymer. Lolu hlobo lwepulasitiki luyingxenye yeqembu le-polyolefin, futhi aluyona i-polar futhi luyi-crystalline kancane. Eceleni kwe-polyethylene, i-polypropylene iyipulasitiki yesibili ekhiqizwa kakhulu emhlabeni, futhi isetshenziswa kakhulu ekupakisheni, ezitsheni, nakwezinye izinhlobo zezimpahla zabathengi nezezimboni kunasekukhiqizweni kwezindwangu.
Lolu hlobo lwepulasitiki lwasungulwa ekuqaleni yinkampani yaseMelika iPhillips Petroleum ngo-1951. Osokhemisi uRobert Banks no-J. Paul Hogan babezama ukuthola uphethiloli ku-propylene, futhi ngengozi badala i-polypropylene. Nakuba lokhu kuhlola kwabhekwa njengokwehluleka, kwasheshe kwaqashelwa ukuthi le nhlanganisela entsha inamandla okulingana ne-polyethylene ezinhlotsheni eziningi zokusebenza.
Nokho, kwaze kwaba ngo-1957 lapho i-polypropylene yenziwa khona into efanelekile ukukhiqizwa ngobuningi. Ngo-1954, isazi semithi sase-Italy uGiulio Natta kanye nozakwabo waseJalimane baphumelela ekwakheni le nto ibe yi-polymer e-isotactic, futhi inkampani yase-Italy iMontecatini yaqala ngokushesha ukukhiqiza le nto ukuze isetshenziswe kwezentengiselwano nabathengi.
I-Polypropylene ekuqaleni yayithengiswa ngaphansi kwegama elithi “Moplen,” futhi leli gama lisalokhu liwuphawu lokuhweba olubhalisiwe lwenkampani iLyondellBasell. Kodwa-ke, kuvame kakhulu ukuthola le nto ibizwa ngokuthi i-polypropylene noma “i-polypro” ngamafuphi.
Isihlalo sedekhi esinekhanophi kanye nesilingi ngendwangu ye-polypropylene enombala ompunga ophuzi
Njengoba ukusetshenziswa kwe-polypropylene kwanda kakhulu ezindleleni eziningi zabathengi kanye nezimboni, kwatholakala kancane kancane ukuthi lolu hlobo lwepulasitiki luphinde lubonise amandla njengendwangu. Indwangu ye-polypropylene iyindwangu engalukiwe, okusho ukuthi yenziwe ngqo ngezinto ngaphandle kwesidingo sokuphotha ukuluka. Inzuzo eyinhloko ye-polypropylene njengendwangu amakhono ayo okudlulisa umswakama; le ndwangu ayikwazi ukumunca noma yimuphi umswakama, futhi esikhundleni salokho, umswakama udlula endwangu ye-polypropylene ngokuphelele.
Lesi sici sivumela umswakama okhishwa ngenkathi ugqoke ingubo ye-polypropylene ukuba uphele ngokushesha kakhulu kunokuba bekungenza ngengubo egcina umswakama. Ngakho-ke, le ndwangu ithandwa kakhulu ezindwangu ezigqokwa eduze kwesikhumba. Kodwa-ke, i-polypro inomkhuba wokumunca nokugcina iphunga lomzimba uma isetshenziselwa izingubo zangaphansi, futhi iyancibilika futhi emazingeni okushisa aphansi. Indwangu ye-polypro encibilikisiwe ingabangela ukusha okukhulu, futhi le nkinga yenza kube nzima ukugeza le ndwangu emazingeni okushisa aphezulu.
Indwangu ye-polypropylene ingenye yezintambo zokwenziwa ezilula kakhulu ezikhona, futhi imelana kakhulu nama-acid amaningi nama-alkali. Ngaphezu kwalokho, ukuhanjiswa kokushisa kwalesi sici kuphansi kunokwezintambo zokwenziwa eziningi, okusho ukuthi ifaneleka kahle kakhulu ekugugeni kwesimo sezulu esibandayo.

Ngaphezu kwalokho, le ndwangu imelana kakhulu nokuklwebheka, futhi imelana nezinambuzane nezinye izinambuzane. Ngenxa yezimfanelo zayo eziphawulekayo ze-thermoplastic, kulula ukubumba ipulasitiki ye-polypro ibe yizimo nezinhlobo ezahlukene, futhi ingaguqulwa ngokuncibilika. Le pulasitiki futhi ayithinteki kakhulu ekuqhekekeni kokucindezeleka.
Kodwa-ke, i-polypro idume ngobunzima bokuyidaya ngemva kokukhiqizwa kwayo, futhi kunzima nokuyibumba ibe yizimo ezahlukene. Le ndwangu isengozini yokulimala kwe-UV, futhi ayinamatheli kahle ku-latex noma kuma-epoxies. Njengazo zonke ezinye izindwangu zokwenziwa, indwangu ye-polypropylene nayo inomthelela omubi kakhulu emvelweni.
Yenziwa Kanjani Indwangu Ye-Polypropylene?
Njengezinhlobo eziningi zepulasitiki, i-polypro yenziwe ngezinto ezitholakala kumafutha e-hydrocarbon njengamafutha e-petroleum. Okokuqala, i-monomer propylene ikhishwa kumafutha aluhlaza ngesimo segesi, bese le monomer ifakwa enkambisweni ebizwa ngokuthi i-chain-growth polymerization ukudala i-polymer polypropylene.
Uma inani elikhulu lama-propylene monomers selihlanganisiwe, kwakheka into eqinile yepulasitiki. Ukuze kwenziwe indwangu engasetshenziswa, i-polypropylene resin kumele ixutshwe nezinhlobonhlobo zama-plasticizer, ama-stabilizer, kanye nama-filler. Lezi zithasiselo zifakwa ku-polypro encibilikisiwe, futhi uma into oyifunayo isitholiwe, le pulasitiki ingavunyelwa ukuthi iphole ibe yizitini noma ama-pellet.
Lawa ma-pellet noma izitini abese edluliselwa efektri yezindwangu, bese encibilikiswa. Ezimweni eziningi, le polypropylene ibe isikhiwa ibe amashidi, noma ingavunyelwa ukuthi iphole ezikhumbeni. Uma kudalwa amashidi, lawa ma-fibre amancane abe esesikwa abe yisimo esifunwayo bese ethungwa noma anamathiselwe ukuze kudalwe izingubo noma amanabukeni. Izindlela ezahlukahlukene zokukhiqiza zisetshenziswa ukwakha i-polypropylene ibe imikhiqizo engeyona eyezingubo.
Isetshenziswa Kanjani Indwangu Ye-Polypropylene?
Indwangu ye-polypro ivame ukusetshenziswa ezimpahleni lapho kudingeka khona ukudluliselwa komswakama. Isibonelo, lolu hlobo lwepulasitiki luvame ukusetshenziswa ukwenza amashidi aphezulu ama-nappies, okuyizingxenye zama-nappies athintana ngqo nesikhumba. Ngokusebenzisa i-polypropylene kule ngxenye ye-nappies, kuyaqinisekiswa ukuthi akukho mswakama ozohlala uthintana nesikhumba somntwana, okunciphisa amathuba okuba kube nokuqubuka.
Izakhiwo zokudlulisa umswakama zale ndwangu engalukiwe nazo zenze yaba yindwangu ethandwayo yezingubo zesimo sezulu esibandayo. Isibonelo, lokhu okwenziwe ngokwenziwa kwasetshenziswa ukwenza izingubo zangaphansi kanye namahembe angaphansi ayesetshenziswa esizukulwaneni sokuqala se-US Army's Extended Cold Weather Clothing System (ECWCS). Kwatholakala ukuthi izingubo ezenziwe ngale ndwangu zithuthukisa induduzo yamasosha ezimweni zesimo sezulu esibandayo, kodwa izinkinga ngezindwangu ze-polypro zenze ukuthi ibutho lase-United States lishintshele esizukulwaneni sakamuva sezindwangu ze-polyester zezinhlelo zabo ze-Generation II kanye neGeneration III ECWCS.
Kwezinye izimo, indwangu ye-polypropylene ingasetshenziswa futhi ukwenza izingubo zemidlalo, kodwa izinkinga eziningana ngalolu hlobo lwepulasitiki zenze izinhlobo ezintsha ze-polyester zathandwa kakhulu kulolu hlelo lokusebenza. Nakuba izakhiwo zokudlulisa umswakama zale ndwangu zifiseleka kakhulu kwezemidlalo, ukungakwazi ukugeza le ndwangu ngamanzi ashisayo kwenza kube nzima ukususa iphunga elivela ezingutsheni zemidlalo ze-polypropylene. Ngaphezu kwalokho, ukuthambekela kwale ndwangu ekulimaleni kwe-UV kwenza kube ukukhetha okubi kunoma yiluphi uhlobo lwezingubo zangaphandle.
Ngaphandle kwezwe lezingubo, ipulasitiki ye-polypropylene isetshenziswa ezinkulungwaneni zezicelo ezahlukene. Enye yezindlela ezidumile zokusebenzisa lesi sithako kusezitsheni zokuphuza; ngenkathi izitsha zazenziwe ngephepha ekuqaleni, i-polypropylene manje iyinto ethandwayo yalolu hlelo. Le pulasitiki isetshenziselwa futhi ukwenza izintambo, amalebula okudla, ukupakishwa kokudla, izibuko zelanga, kanye nezinhlobo ezahlukene zezikhwama.
Ikhiqizwa Kuphi Indwangu Ye-Polypropylene?
IShayina njengamanje ithumela ngaphandle imikhiqizo ye-polypropylene enkulu kunazo zonke. Ngo-2016, amafektri kuleli lizwe akhiqize inani elikhulu lamapulasitiki e-polypro anenani elingamaRandi ayizigidi eziyizinkulungwane ezingu-5.9, futhi kulindeleke ukuthi lo mzila uzohlala uzinzile esikhathini esizayo esibonakalayo.
Iningi lale nto lenziwa naseJalimane; leli lizwe likhiqize cishe amaRandi ayizigidi eziyizinkulungwane ezingu-2.5 e-polypropylene ngo-2016, kanti i-Italy, iFrance, iMexico, neBelgium nazo zingabakhiqizi ababalulekile balo mkhiqizo. Ngo-2016, i-United States ikhiqize amaRandi ayizigidi eziyizinkulungwane ezingu-1.1 emikhiqizweni ye-polypro.
Umdlali omkhulu embonini yokukhiqiza i-polypropylene yamazwe ngamazwe yiLyondellBasell. Le nkampani ibhaliswe eNetherlands, futhi inezisekelo zokusebenza eHouston naseLondon.
Iqembu eliphume endaweni yesibili kulo mkhakha yiSinopec Group, eseBeijing, kanye nePetroChina Group, nayo eseBeijing. Abakhiqizi abayi-10 abaphambili balo mkhiqizo bakha amaphesenti angama-55 omkhiqizo wonke we-polypropylene emhlabeni jikelele.
I-Polypropylene icutshungulwa ibe yizindwangu emhlabeni wonke. Umkhiqizi omkhulu wezindwangu ze-polypro eziqediwe yiShayina, futhi lolu hlobo lwendwangu luthungelwa ezingutsheni nakwezinye izinhlobo zezindwangu eNdiya, ePakistan, e-Indonesia, nakwamanye amazwe amaningi.
Ingakanani Indwangu yePolypropylene Ebizayo?

Njengoba i-polypro ingenye yezinhlobo zepulasitiki ezikhiqizwa kakhulu, ngokuvamile ayibizi kakhulu ngobuningi. Inani elikhulu lezimboni ezinkulu ezahlukene liyancintisana ukuze libambe imakethe yepulasitiki yomhlaba, futhi lo mncintiswano wehlisa amanani.
Kodwa-ke, indwangu ye-polypropylene ingase ibize kakhulu. Isizathu esiyinhloko salokhu kukhuphuka kwentengo ukuntuleka kwesidingo; kuyilapho indwangu ye-polypropylene yayivame ukusetshenziselwa ukwenza izingubo zangaphansi ezishisayo kaningi, intuthuko yakamuva ekukhiqizweni kwe-polyester yenze lolu hlobo lwendwangu lwaphelelwa yisikhathi kakhulu. Ngakho-ke, lolu hlobo lwendwangu lubiza kakhulu kubakhiqizi bezindwangu kunezindwangu zokwenziwa ezifanayo, njenge-polyester, futhi le ndleko ekhuphukile ngokuvamile idluliselwa kumthengi wokugcina.
Nokho, kubalulekile ukucacisa ukuthi le ndleko ekhuphukile isebenza kuphela endwangu ye-polypropylene eyenzelwe ukwenziwa izingubo. Izinhlobo ezahlukene zendwangu ye-polypropylene ezingafaneleki izingubo zithengiswa ngamanani aphansi, futhi ngokuvamile azibizi kakhulu. Lezi zindwangu ziza ngemibala ehlukahlukene kanye nokuthungwa okuhlukahlukene.
Yiziphi izinhlobo ezahlukene zendwangu ye-polypropylene ezikhona?
Izinhlobo ezahlukene zezithasiselo zingafakwa ku-polypro ngenkathi isesimweni sayo soketshezi ukushintsha izimfanelo zale nto. Ngaphezu kwalokho, kunezinhlobo ezimbili ezinkulu zale pulasitiki:
• I-polypropylene ye-homopolymer: Ipulasitiki ye-polypro ibhekwa njenge-homopolymer uma isesimweni sayo sokuqala ngaphandle kwezithasiselo. Lolu hlobo lwepulasitiki ye-polypro ngokuvamile alubhekwa njengento enhle yendwangu.
• I-Copolymer polypropylene: Izinhlobo eziningi zezindwangu ze-polypropylene ziyi-copolymer. Lolu hlobo lwepulasitiki ye-polypro luhlukaniswe kabanzi nge-block copolymer polypropylene kanye ne-random copolymer polypropylene. Amayunithi e-co-monomer ngesimo se-block sale pulasitiki ahlelwe ngamaphethini ajwayelekile esikwele, kodwa amayunithi e-co-monomer ngesimo esingahleliwe ahlelwe ngamaphethini angahleliwe. Noma yiliphi i-block noma i-polypropylene engahleliwe ifanele ukusetshenziswa kwendwangu, kodwa i-block polypro plastic isetshenziswa kakhulu.
