Izinto ze-Polythene sezibe yisisekelo kulo lonke uhlobo lokukhiqiza, ukupakisha, ezolimo, ukwakha, kanye nezimpahla zabathengi ngenxa yezici zazo eziguquguqukayo nezindleko ezingabizi. Amabhizinisi athembele ku-polythene ukuze enze izingxenye ezilula, ama-film okuvikela, nezitsha eziqinile ezingakhiqizwa ngesivinini esikhulu nangendleko ephansi yeyunithi. Emikhakheni eminingi, ukulinganisela kwe-polythene kwamandla omshini, ukumelana namakhemikhali, nokucubungula kuvumela abaklami nabanjiniyela ukuthi bahlangabezane nemigomo yokusebenza ngaphandle kwezindleko ezingaphezu kwemali. Ukusetshenziswa kabanzi kwe-polythene kuphinde kuholele ekucatshangweni kwezixhumanisi zokuhlinzekwa, kusukela ekutholeni i-resin kuya ezinhlelweni zokugaywa kabusha, futhi kuthinta amasu okuthenga izinto ezibonakalayo. Ezinkampanini ezihlola ozakwethu bezinto ezibonakalayo noma ezihlukanisa imigqa yemikhiqizo, ukuqonda izigaba ze-polythene nezinketho zokuhlinzekwa kubalulekile ukunciphisa ubungozi nokwenza ngcono ukukhiqiza. Izinhlangano ezifana ne-Qingdao Xinfeng Jincheng International Trade Co., Ltd. zivame ukubizwa njengezihlinzeki zomhlaba wonke futhi zingathintwa ngekhasi lazo le-HOME noma le-Products ukuze uthole izinketho zokuthenga nokusekelwa kwezobuchwepheshe.

I-Polythene, evame ukubizwa nge-polyethylene noma i-polyethylene polythene emibhalweni yezobuchwepheshe, iyipolima ye-thermoplastic eyakhiwe ngamayunithi aphindaphindayo e-ethylene monomer (–CH2–CH2–)n ahlelwe emaketangeni amade e-hydrocarbon. Izimo ze-polymerization nama-catalyst anquma ubude beketango, ukuhlukana, nokusatshalaliswa kwesisindo samamolekyuli, okonaquma izakhiwo zemishini, ezokushisa, nezokugeleza. Ngokwemvelo, umgogodla we-polythene uyikhabhoni eligcwele, okuyinika ukumelana nokuhlukana kwamanzi nezincibilikisi eziningi ngenkathi ihlaselwa ukubola kwe-oxidative ngaphansi kokuchayeka ku-UV ngaphandle kokuthi iqiniswe. Ubuchwepheshe obuhlukahlukene be-polymerization (isb., izinqubo ezishukumiswa yi-free radical vs. catalyst) zikhiqiza izakhiwo ezincane ezihlukene njengokuhlukana okude kweketango noma uqondile, lokhu okokugcina kuvamile ku-polyethylene enesisindo esikhulu (i-polyethylene enesisindo esikhulu noma i-HDPE). Ngokombono wokucubungula, ukuziphatha kwe-melt kwezintandokazi ze-polythene kuthinta ukukhethwa kwezindlela zokukhiqiza—ukukhipha ifilimu, ukubumba ngomjovo, ukubumba ngomoya, nokubumba okujikelezayo zonke izindlela ezivamile ezisetshenziswa nezinhlobonhlobo ezahlukene ze-polythene.

I-polythene enobuningi obuncane, evame ukubizwa nge-LDPE, ibonakala ngokuba namagatsha amaningi amafushane namade anciphisa ukwakheka kwayo futhi enze impahla enokuguquguquka okuphezulu nokucaca. I-LDPE isetshenziswa kabanzi ezinhlelweni zokupakisha eziguquguqukayo njengezikhwama zegrosari, ama-shrink films, nama-multilayer laminates adinga ukuqina nokwelulwa. Ubuningi obuncane bempahla buphinde buphumelele ekunciphiseni isisindo ekupakisheni, okunganciphisa ukukhishwa kwezinto zokuthutha ngeyunithi lapho kuklanywe kahle. Ukucubungula i-LDPE kuvame ukubandakanya i-film extrusion kanye ne-blown film techniques, lapho amandla okuncibilika kanye ne-draw-down ratios kuyizinto ezibalulekile zenqubo ezichaza ukusebenza kwe-film. Ngenkathi i-LDPE inikeza ukumelana okuhle kakhulu nokukwazi ukubopha, amabhizinisi kufanele alawule imifudlana yayo yokugaywa kabusha ngokuhlukile kwezinhlobo eziqinile ukuze kuqinisekiswe ukubuyiselwa kahle kwezinto kanye nokujikeleza.

I-High density polyethylene (i-polyethylene enobuningana obuphezulu noma i-HDPE) iyipholimela eliqondile elinomkhawulo omncane wokuhlukana, okwenza izinga eliphezulu lokukristaliswa futhi kuholele ezintweni eziqinile, eziqinile ezifanele izicelo eziqinile. I-HDPE iyisinqumo esikhethwayo seziqukathi ezibunjwe ngomoya, izimbiza zobisi, iziqukathi zamakhemikhali, nezinhlelo zokudlulisa amanzi ngenxa yokumelana kwayo okuhle kakhulu nokungathathi hlangothi kwamakhemikhali. Engqalasizinda, ukudlulisa amanzi kwe-HDPE kukhethwa kakhulu ekusabalaliseni amanzi, ukudonsa amanzi, nokudlulisa igesi ngenxa yokuguquguquka kwayo, ubuqotho bezixhumanisi (nge-heat fusion), nokuphila isikhathi eside. Ngokombono wokucubungula, i-HDPE idinga amaphrofayili okushisa ahlukene kanye nemiklamo yezikrufu ekukhipheni nasekubunjweni uma kuqhathaniswa ne-LDPE, futhi ukusebenza kwayo kungathuthukiswa ngezithako ezinjengezihlanganisi ze-UV nezokuvimbela i-oksijeni. Izinto ezithinta uchungechunge lokuhlinzekwa kwe-HDPE zihlanganisa ukukhethwa kwebanga lokubunjwa ngomoya ngokumelene nokukhipha kanye nokusetshenziswa kokuqukethwe kwe-HDPE okusebenzisekayo ukuze kufezekiswe izinhloso zokusimama ngaphandle kokudela ukusebenza komshini.

I-Linear low-density polythene, noma i-LLDPE, ikhiqizwa kusetshenziswa izindlela zokuhlanganisa ezethula amagatsha amafushane alawulwayo ngama-comonomers afana ne-butene noma i-hexene. I-LLDPE ihlanganisa amandla aphezulu okwelula namandla angcono okumelana nokubhoboza, okwenza ilungele izicelo ezifana ne-stretch wrap, ama-agricultural films, kanye nama-flexible liners. Ukuqina kwayo okulinganiselayo kanye nezakhiwo zokunamathela kubalulekile ekwelulweni kwe-pallet nasezintweni ezimboza i-silage, lapho ukugcinwa komthwalo nokumelana nesimo sezulu kubalulekile. Abacubunguli bavame ukukhetha i-LLDPE ezinhlelweni ze-cast ne-blown film ngoba ingahlanganiswa ukuze kwakhiwe izakhiwo eziningi ezinezici ezihlukahlukene zokuvimbela kanye nezemishini. Ezinkampanini ezihlosiwe ama-performance films, ukuhlanganisa i-LDPE, i-LLDPE, kanye ne-HDPE ezintanjeni ze-co-extrusion kuvumela ukuthuthukiswa kwezindleko, ukucaca, namandla ezidingweni zomkhiqizo ezithile.

Ngaphandle kwe-LDPE, i-HDPE, ne-LLDPE, kunezinhlobo eziningi ezikhethekile ze-polythene njenge-expanded polyethylene (evame ukusetshenziswa ukuvikela ukushaqeka nokufakelwa okushisayo) nezinhlobo ezixhunyiwe ukuze kuthuthukiswe ukuzinza okushisayo. I-expanded polyethylene, ngezinye izikhathi ethengiswa ngaphansi kwamabanga e-foam, iyinto evaliwe-cell evame ukusetshenziswa ekupakisheni okuvikelayo, ezintweni zemidlalo, nasekuvikeleni ngoba ihlanganisa isisindo esilula nezici zokunqamula. Ngaphezu kwalokho, i-polypropylene (i-pp polyethylene kwezinye izimo zokuhweba) ivame ukuhlanganiswa noma ukucutshungulwa ndawonye ezinhlelweni eziningi lapho kudingeka ukumelana nokushisa okuphezulu noma ukuqina okuhlukile; lezi zingxube zingandisa ukusebenza kodwa zidinga ukuklama okunakekelayo ukuze kuqinisekiswe ukusebenziseka kabusha nokuhambisana nokucubungula. Ezinye izinhlobo ezikhethekile zifaka phakathi izinhlobo ezikhuthazwe yi-metallocene, i-bimodal HDPEs zezicelo zamapayipi, nezinhlobo eziguqulwe i-viscosity ukuze kuthuthukiswe ukucubungula ezindaweni eziyinselele zokukhipha. Ukukhetha phakathi kwalokhu okuhlukahlukene kuncike ezintweni ezibalulekile zesicelo njengokusebenza komgoqo, amandla okushaqeka, imingcele yokushisa, nezindlela zokuphela kwempilo.

Izinto ze-Polythene zinikeza inhlanganisela ebalulekile yokuqina komshini, ukumelana nomswakama namakhemikhali amaningi, kanye nokuminyana okuphansi okunciphisa isisindo somkhiqizo ngaphandle kokudela ukusebenza. Lezi zici zenza i-polythene ibe yisinqumo esisebenza kahle kwezindleko zokupakisha abathengi, iziqukathi zezimboni, nezingxenye lapho ukusebenza kwesikhathi eside kanye nezindleko zokukhiqiza eziphansi kubalulekile. Ukucubungula kwempahla nakho kuvumela abakhiqizi ukuthi bakhiqize izimo eziyinkimbinkimbi nezingxenye ezinezinga eliphansi ezizoba nzima noma zibize kakhulu ngezinto ezihlukile. Ngokombono wezinto zokuhambisa, imikhiqizo ye-polythene elula inciphisa izindleko zokuthumela kanye nokukhishwa kwegesi elibangela umphumela wokushisa uma nje umklamo wokupakisha ulungisiwe ukuze ugweme ukuchitha okungadingekile. Ukugcinwa nokuqina kwezicelo ezifana namapayipi namafilimu angaphandle kuyaqhubeka nokuqinisa inani eliphelele lesikhathi sokuphila, njengoba i-polythene ivame ukudinga ukushintshwa kaningi kunezinye izinto ezisebenza ngaphansi kwezimo ezifanayo.

Nakuba i-polythene inezinzuzo eziningi ezisebenzayo, umthelela wayo emvelweni uhlala ubalulekile kubakhiqizi nabalawuli. Ukugaywa kabusha komshini wezinhlobo ze-polyethylene polythene—ikakhulukazi i-HDPE ne-LDPE—sekuyiminyaka eminingi, futhi kunezinhlelo ezivalekile zezinhlobo ezithile zezitsha nezokupakisha. Kodwa-ke, ukungcola, udoti wezinhlobo ezixubile, kanye nezingqimba eziningi kwenza kube nzima ukugaywa kabusha futhi kunciphise ikhwalithi yomkhiqizo, okudala izinselele ekujikelezeni. Izinketho ezithuthukisiwe njengokugaywa kabusha kwamakhemikhali (i-depolymerization noma i-pyrolysis) zingaguqula udoti we-polyethylene oxubile ube ama-monomers okudla noma amafutha, kodwa ubuchwepheshe buphelele buyanda futhi budinga ezomnotho ezinhle kanye nezakhiwo zokulawula. Izinto ezikhulisiwe ze-polyethylene foams kanye nezingqimba ezixubile zethula izithiyo ezengeziwe; ngakho-ke, ukuklama umkhiqizo ukuze ugaywe kabusha, ukulebula okucacile, kanye nokubambisana nabalingani abaphatha udoti kuyizinyathelo ezibalulekile zokuthuthukisa imiphumela yokuphela kwempilo. Izinkampani zingabandakanya abahlinzeki nabasizi—bona amakhasi e-Products kanye ne-Contact Us ukuze uthole ubudlelwano obungaba khona—ukuze zisebenzise izinhlelo zokugaywa kabusha futhi zithole izinhlobo ezisetshenziswe kabusha ezihlangabezana nezinhloso zokulawula nezokumaketha.

Ukwamukela izindlela ezingcono kakhulu kuwo wonke umklamo womkhiqizo, ukuthengwa, nokuphathwa kokuphela kokuphila kusiza amabhizinisi ukunciphisa udoti we-polythene futhi kuthuthukise izilinganiso zokuzinza. Amasu omklamo ahlanganisa ukunciphisa ubukhulu bezinto ngenkathi kugcinwa ukusebenza ngokusebenzisa i-geometry elungisiwe, ukukhetha imiklamo ye-mono-material ukwenza lula ukugaywa kabusha, nokucacisa izinhlobo ezisetshenziswe kabusha lapho kufanele khona. Ngokusebenza, ukuqaliswa kwezinhlelo zokubuyisa, ukubambisana nabagayeli abaqinisekisiwe, nokutshala imali ekuhlukaniseni endaweni yemfucuza yangemuva kokukhiqiza kungabuyisa inani futhi kunciphise isidingo sezinhlobo ezintsha. Lapho ukusetshenziswa kwe-polythene kungagwenywa khona, izinto ezisebenza njengekhadibhodi engagaywa kabusha, ama-film angakwazi ukubola (ezinhlelweni ezifanele), noma iziqukathi ezingasetshenziswa kabusha kungaba ngcono; noma kunjalo, ukuhlola kufanele kucabangele imiphumela ephelele yomjikelezo wokuphila kunokugxila ezicini ezingezona ezibalulekile. Abahlinzeki njengenkampani emelwe ngamakhasi e-HOME kanye ne-About Us bavame ukuhlinzeka ngosizo lobuchwepheshe ukusiza amakhasimende ukuthi alungise amafomula ukuze agaywe kabusha futhi ahlolisise i-pp polyethylene noma okunye ukuhlanganiswa kwe-polymer kwezidingo ezithile.

Izinkampani ezifuna imigqa yokuhlinzekwa kwe-polythene ethembekile kufanele zihlole abahlinzeki ngokwesekhono, izinhlelo zokuqinisekisa ikhwalithi, kanye neziqu zokuzinza. Izinto okufanele zihlolwe zihlanganisa izitifiketi, ukulandelelwa kwe-resin, amashidi ezobuchwepheshe atholakalayo, kanye nokuzimisela ukuthuthukisa izigaba ezihambisana nezidingo zomkhiqizo. Ukuvakashela izincwadi zemikhiqizo zabahlinzeki kanye nezinsiza zebhulogi kungahlinzeka ngokuqonda ngezici zezinto, izindaba ezithile, nezincomo zokucubungula ezinganciphisa ubungozi bokukhetha izinto. Ngokwesibonelo, amakhasi Emikhiqizo kanye Nebhulogi axhunywe kulesi sihloko angaba izindawo zokuqala zokuhlola izinhlu zamasampula, ukuhambisana kwemishini, kanye nezibuyekezo zemboni. Ukusungula imingcele ecacile yekhwalithi nokufaka izinhlinzeko zezinhloso zokuqukethwe okusebenzisekayo kabusha ezinkontilekeni zokuthenga kuzohambisana nezinhlelo zokuhlinzekwa nezinjongo zokuzinza ezinkampanini ngenkathi kugcinwa amazinga okusebenza.

Izinto ze-Polythene zisadingeka kakhulu ezimbonini ezahlukahlukene ngenxa yokusebenza kwazo okuhlukahlukene, ukubiza okuncane, nezici zokucubungula ezithandayo. Ukuqonda umehluko phakathi kwe-LDPE, i-HDPE, i-LLDPE, i-polyethylene eyandisiwe, namaxube akhethekile njenge-pp polyethylene kubalulekile ukukhetha impahla efanele yesicelo esithile nokuklama imikhiqizo ehambisana nokusebenza nokusimama.
