Izinto ze-Polythene, ezaziwa kabanzi njenge-polyethylene noma i-polythene, zakha omunye womndeni omkhulu kakhulu we-polymers osasetshenziswa embonini yesimanje. Lezi zinto ziyi-thermoplastics ezitholakala kuma-monomers e-ethylene futhi zenziwa ukuhlangabezana nezidingo ezahlukahlukene zokusebenza komshini, ezokushisa, nezokhemikhali. Kulesi sihloko, sizobeka isiteji sokuthi izinhlobo ze-polythene zikhethwa kanjani ezokupakisha, ezokwakha, izingxenye zezimoto, imishini yezokwelapha, nemikhiqizo yabathengi. Ukuqonda i-chemistry eyisisekelo nezindlela zokucubungula kusiza amabhizinisi akhethe izinga elifanele izicelo ezithile nezinjongo zokujikeleza kwempilo. Njengomphakeli kanye nomlingani wokuhweba kulo mkhakha, izinkampani ezifana ne-Qingdao Xinfeng Jincheng International Trade Co., Ltd. (ebhekiselwe kuyo ekhasini le-HOME) zinikeza i-portfolio yezinto zokwakha zamaplastiki ezihlanganisa izigaba eziningi ze-polythene nemishini ehlobene yokucubungula.

Izinto ze-Polythene zihlukaniswa ngokuminyana nokuhlukana: i-high density polyethylene, i-low density polyethylene, i-linear low density polyethylene, ne-expanded polyethylene phakathi kwezinye. Uhlobo ngalunye lunikeza ukuziphatha okuhlukile komshini: i-high density polyethylene (evame ukufushaniswa njenge-HDPE) ibonisa amandla aphezulu okudonsa, ukumelana namakhemikhali, nokuqina, okwenza ilungele iziqukathi, imibhobho, nezingxenye zezimboni. Izinhlobo ze-low density polyethylene ne-linear low density zigxila ekuguquguqukeni, ukumelana nomthelela, nokubeka uphawu, okufanele amafilimu, imibhobho eguquguqukayo, nokupakisha okubeka uphawu ngokushisa. I-Expanded polyethylene (EPE) yakhelwe ezakhiweni ezifana neseli noma i-foam enikeza ukugcwalisa nokuvikela ukushisa ekupakisheni kwezokuthutha nasezifakweni zokuvikela. I-polythene egaywe kabusha iyatholakala njalo, inikeza inketho eqaphela imvelo ezinhlotsheni eziningi zokugcina izinto ngenkathi idinga ukukhethwa ngokucophelela ukuze ihambisane nokusebenza kwe-virgin-grade.

Ukukhetha phakathi kwezinhlobo lezi kuncike ezintweni ezithinta ukusebenza njengemodulus, ukunwebeka lapho kuphuka, inkomba yokugeleza kwe-melt, kanye nokumelana nokudabuka kwemvelo okubangelwa ingcindezi. I-polyethylene enobuningi obuphezulu iyathandwa lapho kudingeka ukuqina nokumelana nokudabuka kwengcindezi, kanti i-polyethylene enwetshiwe ikhethwa ukuze kube nokuvikela okungasindi. I-polyethylene egaywe kabusha inikeza izinzuzo zezindleko nokusimama kodwa ingase yethule ukungafani kombala, iphunga, kanye nezakhiwo zemishini ngaphandle kokuthi igaywe kabusha futhi ihlolwe kahle. Izithako zesimanje kanye nama-compatibilizers avumela amafomula alinganisa okuqukethwe okugaywe kabusha nezinhloso zokusebenza, okuvumela izinhloso zomnotho oyindilinga ngaphandle kokudela ukwethembeka komkhiqizo. Abahlinzeki nabakhiqizi basebenzisana ukucacisa amabanga ahlangabezana nezindinganiso zomthetho kanye nezinqubo zokuhlola ezithile zezicelo.

Izinto ze-Polythene zihambisa isiphakamiso senani esiphumelelayo kuyo yonke imikhakha ngoba zihlanganisa izindleko eziphansi, ukukhiqizwa, kanye nemikhakha ebanzi yezakhiwo ezibonakalayo. Imvelo yazo ye-thermoplastic ivumela izindlela zokucubungula ezisebenzayo ezisheshayo njengokukhipha, ukubumba ngomoya, ukubumba ngomjovo, nokubeka ifilimu, okwehlisa izindleko ngeyunithi ekukhiqizeni okukhulu. Ezokupakisha, amafilimu e-polyethylene polythene ahlinzeka ngezithiyo ezinhle kakhulu zomswakama, ukubeka uphawu, nezinketho zokucaca; lezi zici zivumela isikhathi eside sokugcina kanye nokunciphisa ukulimala komkhiqizo ngesikhathi sokusabalalisa. Ekwakhiweni nasezingqalasizinda, izinhlelo zemibhobho ye-HDPE zinikeza isikhathi eside sokuphila, ukumelana namakhemikhali, nokugcinwa okuphansi uma kuqhathaniswa nezinto zendabuko ezifana nensimbi noma ukhonkolo.

I-Polythene iphinde ixhaswe izinhlelo zokunciphisa isisindo ezimotweni nasezintweni zabathengi, lapho isisindo esincishisiwe siholela ekunciphisweni kokusetshenziswa kwamandla nezindleko zokuhambisa. Ukumelana namakhemikhali kwempahla kanye nokungangeni kwayo kubenza balungele izitsha zamakhemikhali, ukupakisha kwemithi, namafilimu ezolimo. Ngaphezu kwalokho, ukwakheka kwe-polythene enezinto ezivikela i-UV, izivimbeli zomlilo, nezishintshi zomthelela kwandisa uhla lwezicelo ezisebenzisa ngaphandle nasezindaweni ezibalulekile zokuphepha. Ngokombono wokukhiqiza, abahlinzeki abanikeza ukwesekwa kwezobuchwepheshe, ikhwalithi ehambisanayo, kanye ne-supply chain ebonakalayo—njengalokhu kuchazwe ekhasini lemikhiqizo—basiza amakhasimende ebhizinisi ukuthi amukele izigaba ezifanele ze-polythene nezisizi zokucubungula ukuze kukhiqizwe kahle.

Naphezu kokuthi izinzuzo ze-polythene zibalulekile, umthelela wemvelo nezinkinga zokuhlala zibalulekile ezingxoxweni zemboni zanamuhla. I-polyethylene ye-virgin ejwayelekile itholakala ezinsizakusebenza ze-petrochemical, ikhulisa ukukhishwa kwegesi eluhlaza emgqeni wamanani. Ukuphathwa kokuphuma kokuphila kuyinkinga enkulu: udoti lwe-polythene oluphathwe kabi lungahlala emvelweni isikhathi eside, luthinta izinhlelo zokuphila nezilwane zasolwandle. Ukuze kubhekwe lezi zinkinga, abakhiqizi nababambiqhaza emgqeni wokuhlinzeka bagxile kakhulu ezinhlelweni zokuphinda zisetshenziswe, ubuchwepheshe bokuphinda bube ne-mechanical ne-chemical, kanye nokwakha ukuze kube lula ukuphinda kusetshenziswe kusukela ekuqaleni.

I-Polyethylene ephindwe kabusha iyindlela esebenzayo yokunciphisa isidingo se-resin entsha kanye nokwehliswa kokuphuma emathuneni. Nokho, ukusebenza nokuhlanzeka kwe-polyethylene ephindwe kabusha kuncike ekuhlukanisweni kwezinto ezisetshenziswayo, ekuhlanzeni, nasezindlela zokuphinda zisebenze. Izinqubo zokuhlunga ezithuthukisiwe kanye nezinsiza zokuhlanganisa ezithuthukisiwe ziyasiza ukukhiqiza ama-resin aphindwe kabusha anekhwalithi ephezulu afaneleka ezinhlelweni ezingezona zokudla, futhi, kwezinye izimo, ezokuxhumana nokudla uma eqinisekisiwe kahle. Enye indlela ukuvuma i-polyethylene esuselwa kubiobased eyenziwe kusuka ezinsizakusebenza ze-ethanol ezivuselelekayo; nakuba ikhemikhali ifana ne-polyethylene polythene, lawa ma-resin anciphisa ubukhulu bokukhanya kwekhabhoni ye-fossil. Amabhizinisi abheka ukuhlala kufanele acabangele ukuhlaziywa kokuphila, izilinganiso zokujikeleza, kanye nokucaciswa kwabaphakeli—izihloko ezivame ukukhuluma ngazo kumakhasi abaphakeli mayelana nathi kanye nezokuhlala—nxa ekukhetheni ozakwethu nezinto.

Ukuqhathanisa i-polythene nezinye izinto zokwenziwa ezifana ne-polypropylene, i-PET, i-PVC, kanye ne-polystyrene kusiza amaqembu okuthenga ukwenza izinqumo ezicacile zokukhetha izinto. I-high density polyethylene ibonakala ngokuhlanganiswa kwayo kokumelana, ukumelana nezinto ezilimazayo, kanye nezindleko eziphusile uma kuqhathaniswa ne-polypropylene, enikeza ukumelana okukhulu nezinga lokushisa kodwa ivamise ukuba nezindleko eziphezulu. I-PET inikeza ukujula okungcono kanye nezici zokuvikela zokupakisha iziphuzo, kanti amafilimu e-polyethylene polythene ahlala eguquguqukayo futhi kulula ukuwafaka ukuze asetshenziswe ekupakisheni nasezikhwameni. I-PVC iyakwazi ukumelana futhi iqinile ezinhlelweni zokwakha kodwa ikhuphula ukukhathazeka mayelana nezinto zokwenza iplastiki kanye nemikhiqizo yokushisa ephuma lapho i-polyethylene igwema.

Ngokombono wokuphinda usebenzise, i-polyethylene (kokubili i-HDPE ne-LDPE) inezinzuzo ezivela ezindleleni zokuphinda usebenzise ezisunguliwe ezindaweni eziningi, nakuba ukungcoliswa nezinga lokuqoqwa kuhluka. I-Expanded polyethylene foam ihluke kakhulu kuma-plastics aqinile ezinketho zokuphuma; nakuba ingaba nendawo enkulu, ubukhulu bayo obuphansi bujolisa ezinkingeni zokuphinda usebenzise ngaphandle kokuthi ibhujiswe. Amabhizinisi kufanele abale izindleko eziphelele zokuba nempahla, ukuphepha komkhiqizo, ukuphinda usebenzise, kanye nokuhambisana nemithetho uma eqhathanisa izinto. Amakhasi edatha yobuchwepheshe nokwesekwa kwabaphakeli—njengokuhlu kwemikhiqizo namakhasi wezincazelo atholakala kumakhasi omkhiqizo wabalingani—kubalulekile ekuqhathaniseni okuhlangene nasekutholeni iziqu.

Izinguquko ezisematheni ezimatheni ze-polythene ziyaqhubeka nokwandisa ukusetshenziswa kwazo emakethe ephezulu yokusebenza kanye nezimakethe ezikhethekile. Ama-foams e-polyethylene akhuliswe ukuze akhiwe ukupakisha okuqhubekayo okuvikela izinto ezithintekayo ze-elektroniki nezinsiza zezokwelapha ngesikhathi sokuhamba. Amathangi e-polyethylene aphezulu, athuthukiswe ngezithako ezivimbela ukugqwala, asebenza ezinhlelweni ezinzima ze-oyela, igesi, kanye nezokumbiwa. I-polyethylene ephinde yasetshenziswa ithola impilo entsha emikhiqizweni yokwakha, efana ne-composite lumber namabhodi okushisa, ihlinzeka ngokuqina ngenkathi ifaka ukuguquguquka. Ngaphezu kwalokho, ubuchwepheshe be-multilayer film obuhlanganisa i-polyethylene nezendlalelo zokuxhuma nezinsiza zokuvikela kuvumela ukupakisha okukhanyayo okuhlinzeka ngokuqinile kokulawulwa kwegesi nokunwetshwa kwamanzi.

Imizamo ye-R&D iphinde ihlole izinga le-polyethylene elisebenzayo: ama-polymer akhanyayo ukuze kube nokupakisha okunciphisa i-static, ukwelashwa kwezindawo eziphilayo ezibhekelele impilo, kanye nezixazululo ezivimbela i-UV zokusebenza kwangaphandle. Ukwakha okungeziwe ngefilaments ezihambisana ne-polyethylene kuyavela ukuze kube nokwakhiwa kwezibonelo kanye nezicucu zokusetshenziswa ezikhethiwe, nakuba izici zokucubungula kufanele ziphathwe. Izinkampani ezibheka amabhulogi namakhasi wezibuyekezo zobuchwepheshe—njengomthombo we-Blog ophathwa abahlinzeki abahamba phambili—zingahlala zazi ngezikhathi zokuhweba futhi zisebenzisane nabakhiqizi bezinto ukuze zihlolwe izixazululo ezintsha nezindlela zokucubungula.

Ikhanda lezinto ze-polythene lizobunjwa yizidingo zokuzinza, intuthuko yemithetho, kanye nentuthuko ekugayeni kabusha nasezintweni eziyisisekelo ezisekelwe ezintweni eziphilayo. Lindela ukwamukelwa okukhulu kwe-polyethylene egaywe kabusha kanye ne-resins enezinga eliphansi lekhabhoni njengoba izinhlobo zokukhiqiza zilandela imigomo ye-net-zero kanye nokuzibophezela ekupakisheni okuyindilinga. Ubuchwepheshe bokugaywa kabusha kwamakhemikhali, obuguqula udoti wepulasitiki oxubile ubuyele ezintweni eziyisisekelo, bungakwazi ukugcwalisa ukugaywa kabusha ngomshini futhi kuvumele izinhlelo ezivalekile zezicelo ezinokubaluleka okuphezulu. Ukubeka kwedijithali ezintweni ezihambisa izimpahla kuzothuthukisa ukulandelelwa kokuqukethwe okugaywe kabusha futhi kuvumele ukuthobela imithetho eguqukayo mayelana namapulasitiki asetshenziswa kanye kuphela kanye nemiyalelo yokuqukethwe okugaywe kabusha.

Abakhiqizi bazoqhubeka nokufeza izixazululo zama-resin ukuze bathuthukise ubudlelwano phakathi kwamandla nesisindo, ukusebenza komgoqo, nokusebenza kahle kokucubungula. Ukubambisana phakathi kwabahlinzeki, abaguquli, namakhasimende kuzoba yisidingo sokuqinisekisa izigaba ze-polyethylene ezisetshenziswe kabusha nezisekelwe kubhayoloji ezicini ezibucayi. Izinkampani ezifuna ozakwethu abathembekile kufanele zibuyekeze amaphrofayili ezinkampani namaphothifoliyo emikhiqizo ngaphambi kokuzibandakanya; isibonelo, ikhasi elithi Mayelana Nathi linikeza ngolwazi oluyisisekelo ngamakhono abahlinzeki nezindlela zokuxhumana zemibuzo yezobuchwepheshe. Ngokulandelela ukuthuthukiswa kwemboni nokutshala imali ekuhlolweni kokuqualify, amabhizinisi angasebenzisa ukuguquguquka kwe-polythene ngenkathi ihambisana nezinjongo zokuzinza.

Lapho kucaciswa izinto ze-polythene, amaqembu okuthenga kufanele acela amakhasi edatha yobuchwepheshe, ukuhamba kwezibonelo, kanye nezivivinyo zokukhiqiza ezincane ukuze kuqinisekiswe ukusebenza ezimweni zokusetshenziswa zokugcina. Izimfanelo ezibalulekile okufanele ziqinisekiswe zifaka phakathi i-melt flow index, ubunzima, amandla okudonsa nokuphuka, ukuziphatha kokushisa, kanye nokuhambisana nezithasiselo nezithako. Ngemikhiqizo ezokwenziwa kabusha, hlanganyela nabalingani bokuhlinzeka ukuze uqinisekise ukuthi udoti ohlangene ungabuyiselwa kahle; lokhu kungabandakanya ukuklama ukupakisha kwe-mono-material noma ukufaka izinhlelo zokubuyisa. Abahlinzeki abanesevisi ezihlanganisiwe nolwazi olucacile lomkhiqizo—okukhonjiswe kumakhasi weMikhiqizo kanye neThintana Nathi—banganciphisa isikhathi sokungena emakethe futhi basize ukuqinisekisa ikhwalithi eqhubekayo.

Ngemikhakha efuna ukuhlola izicelo ze-polyethylene ephinde yenziwe noma ye-polyethylene eyandisiwe, bhala izitifiketi ezidingekayo futhi ubandakanye labholo lwesithathu ukuze kwenziwe ukuhlolwa kokuhamba noma kokusebenza lapho kudingeka. Cabanga ngokwenza ukuhlolwa kokuphila ukuze quantify izinzuzo zemvelo futhi usekele izimangalo zokumaketha. Bamba iqhaza amaqembu e-R&D kanye nezokulawulwa kusenesikhathi enqubweni yokwakha ukuze kuhlolwe ukwehluka phakathi kwezindleko, ukusebenza, kanye nokusimama. Ukusungula ubudlelwano besikhathi eside nabahlinzeki abanamava kuzokwenza kube lula ukufinyelela ezingeni elithuthukayo nasekuthuthukisweni kwezindlela ezithuthukisa kokubili ukusebenza komkhiqizo kanye nemiphumela yemvelo.
