ngethimba lokusekelwa kwe-SEWORT • Meyi 25, 2022
Iyiphi indwangu ye-polypropylene?
Indwangu ye-polypropylene yigama elisetshenziselwa ukuchaza noma yimuphi umkhiqizo wezindwangu osuselwa ku-thermoplastic polymer polypropylene. Lolu hlobo lwepulasitiki luyingxenye ye-polyolwefin Group, futhi yi-non-polar ne-crystalline ngokwengxenye. Eduze kwe-polyethylene, i-polypropylene iyipulasitiki yesibili ekhiqizwa kakhulu emhlabeni, futhi ivame ukusetshenziswa kakhulu ekuphayisheni, utshani, kanye nezinye izinhlobo zabathengi nezimpahla zezimboni kunangaphambili.
Lolu hlobo lweplastiki ekuqaleni lwakhiwa yi-American Corporation Phillips Petroleum ngo-1951. Amakhemikhali ama-Robert Banks noJ. Paul Hologan bebezama ukuthola uphethiloli kusuka kuPoppylene, futhi badale ngephutha polypropylene. Ngenkathi lokhu kuhlolwa kuthathwa njengokuhluleka, kwaqashelwa ngokushesha ukuthi le nhlanganisela entsha inamandla okuba se-POLYETYLENE ngezicelo eziningi.
Nokho, kwaze kwaba ngu-1957, ukuthi i-polypropylene yenziwa yaba yinto efanele ukukhiqizwa kwabantu abaningi. Ngo-1954, usokhemisi wase-Italy uGiulio Natta futhi uzakwabo waseJalimane waphumelela ukwakha le nto ku-asotactic polymer, futhi i-Italian Corporation Montecatini yaqala ukukhiqiza le nto ukuze isebenze ngokuthengisa nabethengi.
I-Polypropylene yasungulwa ekuqaleni ngaphansi kwegama elithi "Mplen," futhi leli gama lisewuphawu lokuthengisa olubhalisiwe lweLoondellbasell Corporation. Kodwa-ke, kuvame kakhulu ukuthola le nto ebizwa ngokuthi yi-polypropylene noma i- "PolyPro" ibe mfushane.

Njengoba ukusetshenziswa kwe-polypropylene kwathandwa kakhulu futhi kuthandwe kakhulu kwizicelo eziningi zabathengi nezimboni, kwatholakala kancane kancane ukuthi lolu hlobo lwepulasitiki luphinde lubonise amandla njengendwangu. Indwangu ye-polypropylene iyindwangu engeyona eyezincwadi, okusho ukuthi yenziwa ngokuqondile kusuka kokuqukethwe ngaphandle kwesidingo sokuxubha kokusolwa. Inzuzo enkulu ye-polypropylene njengendwangu yayo yokudlulisa umswakama; Le ndwangu ayikwazi ukudonsa noma yimuphi umswakama, futhi esikhundleni salokho, umswakama udlula ngendwangu ye-polypropylene ngokuphelele.
Le mfanelo ivumela umswakama oxoshwa ngenkathi ugqoke ingubo ye-polypropylene ukuhwamuka ngokushesha okukhulu kunalokho obekuzogcina ngengubo yomswakama. Ngakho-ke, le ndwangu iyathandwa ngezindwangu ezigqokwa eduze kwesikhumba. Kodwa-ke, i-PolyPro inomkhuba wokuthola nokugcina amaphunga omzimba lapho isetshenziselwa izigqoko zangaphansi, futhi futhi iyancibilika emazingeni okushisa aphansi. Indwangu ebilayo polypro ingadala ukushiswa okukhulu, futhi lolu daba luphinde lwenze lube nzima ukugeza le ndwangu emazingeni okushisa aphezulu.
I-Polypropylene Fabric ingenye yemicu emihle kakhulu yokwenziwa ebukhoneni, futhi kuyamelana kakhulu nama-acids kanye ne-alkalis. Ngaphezu kwalokho, ukuthuthuka okushisayo kwale nto kuphansi kunaleyo yemicucu yokwenziwa kakhulu, okusho ukuthi ilungele ukugqokwa kwesimo sezulu esibandayo.
Indwangu ye-beige ne-white
Ngaphezu kwalokho, le ndwangu imelana kakhulu ne-abrasion, futhi nayo iyamelana nezinambuzane nezinye izinambuzane. Ngenxa yezimpawu zayo eziphawuleka ze-thermoplastic, kulula uku-MoldPro Plastistap Plastice ngezimo ezahlukahlukene namafomu, futhi kungaguqulwa ngokuncibilika. Lepulasitiki nayo ayitholakalanga kakhulu ekucindezelekeni.
Kodwa-ke, i-polypro inzima ukudaya ngokudabukisayo ngemuva kokukhiqizwa, futhi kunzima futhi ukwakheka le ndwangu ibe ukwakheka okuhlukile. Le ndwangu itholakala ekulimaleni kwe-UV, futhi ayinamathele kahle ku-latex noma epoxies. Njengazo zonke ezinye izindwangu zokwenziwa zendwangu, i-polypropylene yendwangu nayo inomthelela omubi kakhulu emvelweni.
Kwenziwa kanjani i-polypropylene yendwangu?
Njengezinhlobo eziningi zamapulasitiki, i-polypro yenziwa ngezinto ezisuselwa kumafutha e-hydrocarbon njengamafutha kaphethiloli. Okokuqala, i-monomer propylene ikhishwe kumafutha aluhlaza efomini legesi, futhi le monomer ifakwa kwinqubo ebizwa ngokuthi yi-polymerization yokukhula kwe-chain ukudala i-polymer polypropylene.
Lapho iningi lama-monomers e-propelene ahlanganiswe ndawonye, kwakhiwa impahla eqinile yepulasitiki. Ukwenza indwangu yezindwangu esebenzisekayo, i-polypropylene resin kumele ihlanganiswe nezinhlobonhlobo zamapulasitiki, izitebhisi, kanye nama-fillers. Lezi izengezo zingeniswa e-molten polypro, futhi lapho into oyifunayo itholakele, lolu pulasitiki lungavunyelwa ukuba luphole kwizitini noma ama-pellets.
Lawa ma-pellets noma izitini ahanjiswa efektri yezindwangu, futhi ayathethelwa. Ezimweni eziningi, le polypropylene yabe senziwa ngamashidi, noma kungavunyelwa ukupholisa isikhunta. Uma amashidi edaliwe, le micu emincane bese igawulwa esimeni esifiselekayo futhi sithungwe noma sithambekele ukudala izingubo noma ama-diaper. Izindlela ezahlukahlukene zokukhiqiza ezahlukahlukene zisetshenziselwa ukwakha i-polypropylene ibe yimikhiqizo engeyona isendlalelo.
Isetshenziswa kanjani i-polypropylene yendwangu?
Indwangu ye-polypro ivame ukusetshenziswa ezisetshenzisweni sezingubo lapho okufunwa khona umswakama. Isibonelo, lolu hlobo lwepulasitiki luvame ukusetshenziswa ukwenza amashidi aphezulu ama-diapers, okuyingxenye yama-diaper athinta ngqo isikhumba. Ngokusebenzisa i-polypropylene yale nto ye-diaper, kuyaqinisekiswa ukuthi akukho umswakama ozohlala uthintana nesikhumba sengane, esehlisa amathuba okubalwa kwakheka.
Le ndawo eyisangumungwane yendwangu engekho emswakama nayo iye yakwenza kube yindwangu ethandwayo yegiya lesimo sezulu esibandayo. Isibonelo, lokhu okwenziwe kwasetshenziselwa ukwenza izingubo zangaphansi futhi zingaphansi ezisetshenziswa esizukulwaneni sokuqala sohlelo lwe-US Army Extended Swelvel System (ECWCS). Kwatholakala ukuthi izingubo ezenziwe kuleli ndwangu zithuthukise ukunethezeka kwamasosha ezimweni zezulu ezibandayo, kepha izinkinga ezinezindwangu ze-polypro zibangele ukuba amasosha ase-United States azoshintshela esizukulwaneni sakamuva se-polyester izindwangu zakamuva ze-polyester II kanye nezizukulwane ze-ecwcs Systems zabo.
Kwezinye izimo, indwangu ye-polypropylene nayo ingahle isetshenziselwe ukwenza izinto zezemidlalo, kepha izingqinamba eziningi ngalolu hlobo lwepulasitiki zenze izinguqulo ezintsha ze-polyester ethandwa kakhulu lolu hlelo lokusebenza. Ngenkathi izakhiwo zendwangu zokuswakama zomswakama zifiseleka kakhulu ezemidlalo, ukungakwazi ukugeza le ndwangu ngamanzi ashisayo kwenza kube nzima ukususa iphunga kusuka ezintanjeni ze-polypropylene. Ngaphezu kwalokho, lokhu kuthambekela kwezindwangu kumonakalo we-UV kwenza kube ukukhetha okungekuhle kunoma yiluphi uhlobo lwe-Outerwear.
Ngaphandle kwezwe lezingubo, ipulasitiki ye-polypropylene isetshenziswa ezinkulungwaneni zezicelo ezahlukahlukene. Okunye kokusetshenziswa okudumile kwale nto ku-string ephuzayo; Ngenkathi ama-STRITS enziwe ekuqaleni ephepheni, i-polypropylene manje seyinto ekhethwayo yalolu hlelo lokusebenza. Lepulasitiki nayo isetshenziselwa ukwenza izintambo, amalebula okudla, ukupakishwa kokudla, izibuko, kanye nezinhlobo ezahlukahlukene zezikhwama.
Ikhiqizwa kuphi i-polypropylene yendwangu?
I-China njengamanje ingumthumeli omkhulu we-polypropylene. Ngo-2016, amafektri kuleli lizwe akhiqize umqulu wePolyPro Plastics abiza ngama- $ 5.9 billion, futhi kucatshangwa ukuthi le trajectory izohlala iqinile ngekusasa elibonakalayo.
Kwenziwa le nto enkulu eJalimane; Leli lizwe likhiqize cishe ama- $ 2,5 billion of polypropylene ngonyaka we-2016, ne-Italy, eFrance, iMexico, futhi iBelgium lingabakhiqizi ababalulekile bale nto. Ngo-2016, i-United States ikhiqize ama- $ 1.1 billion kwimikhiqizo yePoyppro.
Umdlali omkhulu ku-InternationalPropylene Production Production InguLlondellbasell. Le nkampani ifakiwe eNetherlands, futhi inezisekelo zokusebenza eHouston naseLondon.
