I-PE ingacutshungulwa futhi yenziwe ngezindlela ezihlukahlukene.Ukusebenzisa i-ethylene njengento eyinhloko eluhlaza, i-propylene, i-1-butene ne-hexene njengama-copolymers, ngaphansi kwesenzo se-catalysts, kusetshenziswa inqubo ye-slurry polymerization noma inqubo ye-polymerization yegesi, i-polymer etholwe ukuhwamuka kwe-flash, ukuhlukaniswa, ukomisa kanye ne-granulation ukuze uthole izinhlayiya ezifanayo ze-polymerization. umkhiqizo oqediwe.Lokhu kubandakanya izinqubo ezifana ne-extrusion yeshidi, ifilimu extrusion, ipayipi noma iphrofayili extrusion, ukubumba igalelo, ukubumba umjovo, kanye nokubumba roll.
I-Extrusion: Ibanga elisetshenziselwa ukukhiqizwa kwe-extrusion ngokuvamile inkomba encibilikayo ingaphansi kuka-1, i-MWD ububanzi obuphakathi.I-MI ephansi ngesikhathi sokucubungula iphumela emandleni afanelekile ancibilikayo.Amabanga abanzi e-MWD afaneleka kangcono ama-extrusions ngoba anezinga eliphezulu lokukhiqiza, ingcindezi ephansi yokuvula ukufa, kanye nokuthambekela okuphansi kokuncibilika kokuncibilika.
I-PE inezinhlelo zokusebenza eziningi ze-extrusion ezifana nezintambo, izintambo, amapayipi, amashubhu namaphrofayili.Ukufakwa kwamapayipi kusuka kumashubhu aphuzi esigaba esincane segesi yemvelo kuya kumashubhu amnyama anezindonga eziwugqinsi angamayintshi angu-48 ububanzi kumapayipi ezimboni kanye nawomasipala.Amapayipi amakhulu odonga angenalutho akhula ngokushesha njengezinye izindlela ezingasetshenziswa esikhundleni semisele yemvula yeziphepho kanye nezinye indle zikakhonkolo.
1.Ishidi kanye ne-Thermoforming: Ulwelwesi lwe-thermoforming lwezipholile eziningi zohlobo lwepikiniki lwenziwe nge-PE ukuze kube nokuqina, isisindo esincane nokuqina.Eminye imikhiqizo yeshidi kanye ne-thermoforming ihlanganisa iziphehli, izingqimba zamathangi, amapuleti nonogada bezitsha, amabhokisi okuthutha kanye namathangi.Ngokusekelwe eqinisweni lokuthi i-MDPE iqinile, imelana nokugqwala kwamakhemikhali futhi ayingeneli, inani elikhulu nelikhula ngokushesha lezicelo zeshidi liyi-mulch noma i-pool bottom i-Muri.
2.I-Blow molding: Ngaphezu kwengxenye eyodwa kwezintathu ye-HDPE ethengiswa e-United States ingeyokubumba izinhlelo zokusebenza.Lokhu kusuka emabhodleleni aqukethe i-bleach, uwoyela wemoto, okokugeza, ubisi namanzi acwengekile kuya eziqandisini ezinkulu, amathangi kaphethiloli wemoto kanye namabhokisi kayinki.Amabanga okubumba anomsindo anezincazelo zokusebenza ezifana namandla ancibilikayo, i-ES-CR nokuqina okufana nalawo asetshenziselwa izinhlelo zokusebenza zeshidi ne-thermoforming, ukuze amamaki afanayo asetshenziswe.
Ukubumba igalelo lomjovo kuvamise ukusetshenziselwa ukwenza iziqukathi ezincane (ngaphansi kwama-ounces angu-16) zokupakisha izidakamizwa, ama-shampoos, nezimonyo.Inzuzo yale nqubo ukuthi amabhodlela akhiqizwa ngokuzenzakalelayo ukususwa kwe-bottleneck, ukususa isidingo sezinyathelo zokuqeda ngemva kokuqeda ngokuvamile ezihlotshaniswa nezinqubo zokubumba i-blow.Ngenkathi amanye amamaki amancane e-MWD esetshenziswa ukwenza ngcono ukuqedwa kwendawo, amamaki e-MWD aphakathi nendawo ukuya kobubanzi avame ukusetshenziswa.
3.Ukubumba komjovo: I-HDPE inezinhlelo zokusebenza ezingenakubalwa, kusukela ezinkomishini zesiphuzo ezinezindonga ezincane ezingasetshenziswa kabusha ukuya kumakani angu-5-gsl adla ingxenye eyodwa kwesihlanu ye-HDPE ekhiqizwa ekhaya.Amabanga omjovo ngokuvamile anenkomba yokuncibilika kuka-5 kuya ku-10 futhi anikeze amamaki okugeleza aphansi okuqina kanye namamaki okugeleza aphezulu okusebenziseka kalula.Ukusetshenziswa kuhlanganisa izidingo zansuku zonke nokudla okuncane odongeni emaphaketheni;Amathini okudla aqinile namakani opende;Ukumelana okuphezulu nezinhlelo zokusebenza zokuqhekeka kwengcindezi yemvelo njengamathangi kaphethiloli wenjini encane kanye namathini kadoti angama-gallon angama-90.
I-4.Rolling: Izinto ezisebenzisa le nqubo ngokuvamile zichotshozwa zibe izinto eziyimpuphu ezingancibilika futhi zigeleze emjikelezweni wokushisa.Izinhlobo ezimbili ze-PE zisetshenziselwa ukugoqa: inhloso evamile kanye nokuxhumanisa.Inhloso evamile ye-MDPE/HDPE ngokuvamile inokuminyana kububanzi obungu-0.935 ukuya ku-0.945 g/CC obune-MWD encane, okuholela kumkhiqizo onomthelela ophezulu one-warp encane kanye nenkomba yenkomba encibilikayo engu-3-8.Amabanga e-MI aphakeme ngokuvamile awafaneleki ngenxa yokuthi awanakho ukumelana nomthelela kanye nokumelana nokuqhekeka kwemvelo okudingekayo emikhiqizweni ebunjiwe.
Ukusebenza okuphezulu kwezinhlelo zokusebenza zisebenzisa izici zayo ezihlukile zamamaki axhumene ngamakhemikhali.Lawa mabanga ageleza kahle phakathi nengxenye yokuqala yomjikelezo wokubumba futhi abe esexhunyaniswa ukuze athuthukise ukumelana kwawo nokuqhekeka kokucindezeleka kwemvelo okuphakeme kanye nokuqina.Ukumelana nokugqoka nesimo sezulu.I-Crosslinked polyethylene ifaneleka ngokukhethekile ezitsheni ezinkulu, kusukela emathangini angama-500 amalitha asetshenziselwa ukuthutha amakhemikhali ahlukahlukene kuya kumathangi okugcina ezolimo angama-20,000.
I-5.Ifilimu: Ukucutshungulwa kwefilimu ye-PE ngokuvamile kusebenzisa ukucubungula ifilimu evunguzayo noma indlela yokucubungula i-flat extrusion.I-PE eminingi ingeyamafilimu amancane futhi ingasetshenziswa ne-Universal Low density PE (LDPE) noma i-Low Density PE (LLDPE) yomugqa.Amamaki efilimu we-HDPE avame ukusetshenziswa lapho kudingeka khona izakhiwo ezinhle kakhulu zokushuba kanye nokungangenisi okuhle kakhulu.Isibonelo, amafilimu e-HDPE avame ukusetshenziswa ezikhwameni zezimpahla, izikhwama zokudla kanye nokupakisha ukudla.
