Incazelo Eningiliziwe Yezimpawu, Amasu Okucubungula kanye Nokusetshenziswa Kwezinto Ze-PE kanye Ne-PP

1. Ukubuka Konke Okubalulekile

I-PE, i-PP, i-PVC, i-PS, i-PC, i-PF, i-EP, i-ABS, i-PA, i-PMMA, njll. zibizwa ngokuthi izinto zepulasitiki, ezaziwa nangokuthi izinto ze-polymer. Ziwuhlobo lwezinto zokwenziwa ezine-plasticity ezenziwe ngamakhemikhali anama-molecule amaningi ngezindlela ezahlukene zokucubungula. Izinto zepulasitiki zinezinzuzo zokuba lula, ezinamandla aphezulu, ukumelana nokugqwala okuhle, kanye nokuvikela okuhle kakhulu. Zisetshenziswa kabanzi ekupakisheni, ekwakheni, ezimotweni, kuma-elekthronikhi, nakweminye imikhakha eminingi.

I-Polyethylene (PE): Iyi-thermoplastic elula, eguquguqukayo enokumelana okuhle kwamakhemikhali. Kuye ngobuningi, ingahlukaniswa phakathi kwe-polyethylene ephezulu (HDPE) kanye ne-polyethylene ephansi (LDPE).

I-Polypropylene (PP): Iyakwazi ukumelana nokushisa okuphezulu, ukumelana namakhemikhali kanye nokuqina, futhi ivame ukusetshenziswa ezingxenyeni zezimoto kanye nezinto zasekhaya.

2. I-Polyethylene (PE)

Izakhiwo Zomzimba Nezamakhemikhali: I-Polyethylene (PE) iyi-polymer eqondile enama-molecule amaningi enesakhiwo sama-molecule esilula kakhulu, esakhiwe ngamayunithi aphindaphindayo "-CH2-CH2-". Lesi sakhiwo sinikeza i-PE izimfanelo ezahlukahlukene zomzimba nezamakhemikhali.

Isisindo Esilula: I-PE inobuningi obuphansi, cishe phakathi kuka-0.91 no-0.96 g/cm³, okwenza kube yinto emele izinto ezilula.

Ukumelana Namakhemikhali: I-PE ikhombisa ukuzinza okuhle kwamakhemikhali maqondana nezixazululo eziningi zama-asidi, izisekelo, kanye nosawoti.

Ukufakwa Kokushiswa Kogesi: Njengento engeyona i-polar, i-PE inokusebenza okuhle kakhulu kokufakwa kogesi.

Ukumelana Nokushisa Okuphansi: I-PE ingagcina izakhiwo zayo ezibonakalayo emazingeni okushisa aphansi njengo-70°C. I-PE ingashintshwa ngemva kokushisa, okwenza kube lula ukuphinda kusetshenziswe futhi kucutshungulwe kabusha.

Izindlela Zokucubungula: Izindlela zokucubungula i-polyethylene ziyahlukahluka futhi zifaka phakathi okulandelayo.

Ukukhipha: okusetshenziselwa ukukhiqiza amapayipi, izendlalelo zokushisa izintambo nezintambo, njll.

Ukubumba Ngemijovo: kufanelekile ukukhiqiza izitsha ezincane, amathoyizi, njll.

Ukubumba Okuvunguzayo: okusetshenziselwa ukukhiqiza amabhodlela nezitsha ezingenalutho.

Ukubumba Okucindezelwe: kufanelekile ukukhiqiza izingxenye zepulasitiki ezinkulu, ezisetshenziselwa ukukhiqiza izinto zokupakisha ezinodonga oluncane kanye namathileyi.

Izinkambu Zohlelo Lokusebenza: I-Polyethylene inezinhlobo eziningi zezinkambu zokusetshenziswa. Nazi ezinye izibonelo zokusetshenziswa okuyinhloko.

Izinto Zokupakisha: Amafilimu e-PE asetshenziswa kabanzi ekupakisheni ukudla nasekupakisheni izimpahla ngenxa yesisindo sawo esincane kanye nokusebenza kahle kokuvikela.

Amapayipi Epulasitiki: Amapayipi e-HDPE avame ukusetshenziselwa ukuthuthwa kwamanzi negesi ngenxa yokumelana kwawo namakhemikhali kanye nokumelana nokuguguleka.

Izintambo Nezintambo: I-PE isetshenziswa kabanzi njengento yokuvikela ekukhiqizeni izintambo nezintambo.

Ezolimo: I-PE isetshenziselwa ukukhiqiza amafilimu ezolimo, njengobuchwepheshe bokumboza inhlabathi.

Insimu Yezokwelapha: Ngenxa yokuhambisana kwayo nezinto eziphilayo kanye nokumelana namakhemikhali, i-PE isetshenziswa nasekukhiqizweni kwamadivayisi athile ezokwelapha.

Imboni Yezimoto: I-PE isetshenziswa ekukhiqizweni kwezingxenye zezimoto, njengezithangi zikaphethiloli nama-bumper, ngenxa yesisindo sayo esincane kanye nokumelana nokushayisana.

3. Izakhiwo Zomzimba Nezamakhemikhali ze-Polypropylene (PP)

I-Polypropylene (PP) iyi-polymer ye-thermoplastic eqondile eyenziwe nge-polymerization yama-monomers e-propylene. I-PP inezakhiwo ezilandelayo ezibonakalayo zomzimba nezamakhemikhali

Ukumelana Nokushisa: Izinga lokuncibilika kwe-PP liphakathi kuka-160 no-170°C, okwenza likwazi ukumelana nokushisa futhi lifanele imikhiqizo edinga ukumelana namazinga okushisa aphezulu.

Ukumelana Namakhemikhali: I-PP iqinile emanzini, usawoti ongaphili, ama-asidi, kanye nezisekelo kodwa isengozini yezinye izinyibilikisi eziphilayo.

Ukuqina: I-PP inokuqina okuphezulu, okuvumela ukuthi igcine isimo sayo ngaphansi kwemithwalo esindayo.

Ukumelana Nokukhathala: I-PP inokumelana okuhle nokukhathala futhi ifaneleka ezinhlelweni ezidinga ukugoba noma ukusonta okuphindaphindiwe. I-PP ingashiswa futhi ipholiswe ngokuphindaphindiwe ngaphandle kokulahlekelwa yizakhiwo zayo zomzimba, okwenza kube lula ukuyiphinda isetshenziswe.

Izindlela Zokucubungula: I-Polypropylene ingacutshungulwa ibe imikhiqizo ehlukahlukene ngokusebenzisa amasu amaningi.

Ukwengezwa: Kusetshenziselwa ukukhiqiza amapayipi e-PP, amashidi, izinduku, njll.

Ukubumba Ngemijovo: Kufanelekile ukukhiqiza imikhiqizo yepulasitiki emincane kuya kwephakathi njengezitsha, izivalo, kanye nezingxenye zezimoto.

Ukubumba Okufuthayo: Kusetshenziselwa ukwenza imikhiqizo emikhulu yepulasitiki engenalutho njengamabhodlela namabhakede. Kusetshenziselwa ukudala izitsha noma amathileyi epulasitiki anezindonga ezincane.

Ukukhiqizwa Kwefayibha: I-PP ingenziwa futhi ibe yifayibha ngezinqubo zokwelula nokweluka izintambo, amakhaphethi, njll.

Izindawo Zokufaka IsiceloI-Polypropylene inezinhlobo eziningi zezicelo, kufaka phakathi izibonelo ezilandelayo.

Imboni Yezimoto: I-PP isetshenziswa kabanzi embonini yezimoto ezingxenyeni zangaphakathi nezangaphandle ngenxa yesisindo sayo esincane kanye nokumelana nokushisa, njengamaphaneli ezinsimbi kanye nama-bumper.

Imboni Yezindwangu: Imicu ye-PP isetshenziswa ekukhiqizeni izintambo, amakhaphethi, nezingubo.

Izinto Zokupakisha: Ngenxa yesisindo sayo esincane kanye nokumelana namakhemikhali, i-PP ivame ukusetshenziswa ezintweni zokupakisha kokubili ukudla kanye nezinto ezingezona ukudla.

Izinto Zasekhaya: I-PP isetshenziswa ekwenziweni kwezitsha eziphephile kuma-microwave, amadrowa esiqandisi, nezinye izingxenye zemishini yasekhaya.

Imboni Yokwakha: Amapayipi e-PP namashidi asetshenziswa ekwakheni izinhlelo zamapayipi nezinto zokuhlobisa.

Insimu Yezokwelapha: Ngenxa yokuhambisana kwayo nezinto eziphilayo, i-PP isetshenziswa nasekukhiqizweni kwezinye izinto zokwelapha ezilahlwayo, njengezirinji namashubhu okuhlola.
