I-PE inokucutshungulwa kwaye yenziwe ngeendlela ezahlukeneyo.Ukusebenzisa i-ethylene njengeyona nto iphambili, i-propylene, i-1-butene kunye ne-hexene njenge-copolymers, phantsi kwesenzo se-catalysts, usebenzisa i-polymerization ye-slurry okanye inkqubo ye-polymerization yegesi, i-polymer efunyenwe ngokunyuka kwe-flash evaporation, ukwahlukana, ukomisa kunye ne-granulation ukufumana amasuntswana afanayo. imveliso egqityiweyo.Oku kuquka iinkqubo ezifana ne-sheet extrusion, ifilimu extrusion, umbhobho okanye iprofayili extrusion, ukubumba ukuvuthela, ukubumba inaliti, kunye nokubumba umqulu.
Extrusion: Ibakala elisetyenziselwa imveliso extrusion ngokubanzi ukunyibilika index ngaphantsi kwe 1, MWD ububanzi medium.I-MI ephantsi ngexesha lokucubungula iziphumo kumandla anyibilikayo afanelekileyo.Amabanga abanzi e-MWD afaneleka ngcono kwi-extrusions kuba anezinga eliphezulu lemveliso, uxinzelelo olusezantsi lokuvula ukufa, kunye nokuthambekela okusezantsi kokunyibilika.
I-PE inezicelo ezininzi ze-extrusion ezifana neengcingo, iintambo, imibhobho, iityhubhu kunye neeprofayili.Ukusetyenziswa kwemibhobho ukusuka kwinqanaba elincinci letyhubhu etyheli yerhasi yendalo ukuya kwiityhubhu emnyama enodonga olungqingqwa eyi-intshi ezingama-48 ububanzi kwimizi-mveliso nemibhobho kamasipala.Imibhobho yodonga olunomngxuma omkhulu edayamitha emikhulu ikhula ngokukhawuleza njengezinye iindlela ezizezinye kwimisele yezaqhwithi kunye neminye imibhobho ehambisa amanzi amdaka.
I-1.Sheet kunye ne-Thermoforming: I-thermoforming lining ye-coolers ezininzi ezinkulu zepikiniki zenziwe nge-PE yokuqina, ubunzima obulula kunye nokuqina.Amanye amaphepha kunye neemveliso ze-thermoforming ziquka iifenders, itanki linings, iipleyiti kunye ne-basin guards, iibhokisi zokuthumela kunye neetanki.Ngokusekwe kwinto yokuba i-MDPE yomelele, iyamelana nokudleka kweekhemikhali kwaye ayingeneli, inani elikhulu nelikhula ngokukhawuleza lezicelo zamaphepha yi-mulch okanye i-pool bottom Muri.
I-2.Blow molding: Ngaphezu kwesinye kwisithathu se-HDPE ethengiswa e-United States yeyokubumba izicelo zokuvuthela.Ezi bhotile zisusela kwiibhotile ezineblitshi, i-oyile yemoto, isefu, ubisi kunye namanzi adiyiweyo ukuya kwiifriji ezinkulu, iitanki zamafutha emoto kunye neekhatriji ze-inki.Amabakala okubumba avuthela anemilinganiselo yokusebenza efana namandla okunyibilika, i-ES-CR kunye nokuqina okufana nezo zisetyenziselwa usetyenziso lwephepha kunye ne-thermoforming, ngoko ke amabakala afanayo angasetyenziswa.
I-injection blow blowing idla ngokusetyenziswa ukwenza izikhongozeli ezincinci (ngaphantsi kwe-16 ounces) zokupakisha amayeza, iishampu, kunye nezinto zokuthambisa.Inzuzo yale nkqubo kukuba iibhotile ziveliswa ngokukhutshwa kwebhotile ngokuzenzekelayo, ukuphelisa imfuno yamanyathelo okugqiba emva kokugqiba ngokuqhelekileyo ezinxulumene neenkqubo zokubumba.Ngelixa amanye amabakala emxinwa e-MWD esetyenziselwa ukuphucula umphezulu wokugqiba, amabanga aphakathi ukuya kububanzi be-MWD aqhele ukusetyenziswa.
I-3.I-injection molding: I-HDPE inezicelo ezingenakubalwa, ukusuka kwiikomityi zesiselo ezinqabileyo ezinodonga oluncinci ukuya kwii-5-gsl iinkonkxa ezisebenzisa i-fifth ye-HDPE eveliswa ekhaya.Amabakala okutofa aqhele ukuba nesalathiso sokunyibilika kwe-5 ukuya kwe-10 kwaye abonelele ngamabakala asezantsi okuqukuqela kokuqina kunye namabakala ahambayo aphezulu obuchule.Usetyenziso lubandakanya iimfuno zemihla ngemihla kunye nokutya okubhityileyo eludongeni lokupakisha;Iitoti zokutya ezinzima kunye neetoti zokupeyinta;Ukuchasana okuphezulu kuxinzelelo lokusingqongileyo kwezicelo zokuqhekeka ezifana neetanki ze-injini ezincinci kunye ne-90 gallon trash cans.
I-4.Rolling: Izinto ezisebenzisa le nkqubo zidla ngokutyunyuzwa zibe ngumgubo onokunyibilika kunye nokuhamba kumjikelezo we-thermal.Iintlobo ezimbini ze-PE zisetyenziselwa ukuqengqeleka: injongo-jikelele kunye ne-cross-linked.Injongo ngokubanzi i-MDPE / HDPE ngokuqhelekileyo inobuninzi kwi-0.935 ukuya kwi-0.945 g / CC uluhlu kunye ne-MWD emxinwa, okubangela imveliso yempembelelo ephezulu kunye ne-warp encinci kunye ne-melt index range ye-3-8.Amabakala aphezulu e-MI awafanelekanga ngenxa yokuba awanakho ukuchasana nempembelelo kunye noxinzelelo lokusingqongileyo oluxhathisayo olufunekayo kwiimveliso ezibunjiweyo.
Ukusetyenziswa okuphezulu kokuqengqeleka kwentsebenzo kuthabatha ithuba leempawu zalo ezikhethekileyo zamabakala adityaniswe ngamachiza.La mabanga ahamba kakuhle ngexesha lenxalenye yokuqala yomjikelezo wokubumba kwaye emva koko adityaniswe ngokunqamlezileyo ukuphuhlisa ukunyanzeliswa koxinzelelo oluphezulu lokusingqongileyo kunye nokuqina.Ukumelana nokunxiba kunye nemozulu.I-Crosslinked polyethylene ifaneleka ngokukodwa kwiibhotile ezinkulu, ukusuka kwiitanki ezingama-500 ezisetyenziselwa ukuthutha iindidi zeekhemikhali kwii-20,000 zeetanki zokugcina ezolimo.
I-5.Film: Ukusetyenzwa kwefilimu ye-PE ngokuqhelekileyo kuthatha inkqubo yokuvuthela ifilimu ngokubanzi okanye indlela yokucubungula i-flat extrusion.Uninzi lwe-PE yeyefilimu ezibhityileyo kwaye ingasetyenziswa nokuba yi-Universal Low density PE (LDPE) okanye i-linear Low Density PE (LLDPE).Amabanga efilimu ye-HDPE aqhele ukusetyenziswa apho iipropathi ezigqwesileyo zokuqina kunye nokungangeni okugqwesileyo kufuneka.Ngokomzekelo, iifilimu ze-HDPE zisetyenziswa ngokuqhelekileyo kwiingxowa zempahla, iingxowa zokutya kunye nokupakishwa kokutya.
