Wonke umuntu kufanele ajwayele iphepha.Ngoba singabona zonke izinhlobo zemikhiqizo yephepha ezigcawini eziningi ekuphileni kwansuku zonke.Isibonelo, sijwayelene nezinkomishi zephepha, izitsha zephepha, amapuleti ephepha namabhokisi okudla okusheshayo.Sonke siyazi ukuthi iphepha liyi-hygroscopic (limunca kalula umswakama) futhi linamandla aphansi okuqhuma.Kodwa uma uqaphele, uzothola ukuthi la maphepha anefilimu yokuthinta ecacile, ecwebezelayo, ebushelelezi ngaphakathi.Leyo yifilimu ye-PE, ebonakala ibeka ijazi lemilingo ephepheni, inikeze amandla amakhulu okungesabi amanzi namafutha.Ake sembule imfihlakalo yephepha eliboshiwe ndawonye!

Yini i-PE?
Ngaphambi kokuqonda iphepha elihlanganisiwe le-PE, ake sikhulume ngempahla yayo eluhlaza - i-polyethylene.I-Polyethylene imfushane ku-PE, okuyi-resin thermoplastic polymerized from ethylene.Ukubukeka kwe-polyethylene yizinhlayiya ze-waxy ezimhlophe ezimhlophe, ezingenakunambitheka, ezingenaphunga, ezingenabuthi futhi zizwakala njengengcina.Isici esiyinhloko se-polyethylene sishibhile, esinokumelana okuhle kakhulu okubandayo, ukuzinza kwamakhemikhali, ukufakwa kukagesi nezinye izici.Ngakho inohlu olubanzi kakhulu lwezinhlelo zokusebenza.Ikakhulukazi esetshenziswa ekwenzeni amafilimu, izinto zokupakisha, iziqukathi, amapayipi, izintambo kanye nezintambo, izidingo zansuku zonke, njll. Ngaphezu kwalokho, ingasetshenziswa njengezinto zokuvikela eziphakeme kakhulu zamathelevishini, ama-radar, njll. Kusukela ukusetshenziswa kwayo ngo-1922, i-polyethylene isithuthuke yaba inhlaka enkulu yokwenziwa emhlabeni kanye nokusetshenziswa okukhulu kwezinto zokupakisha zepulasitiki.Inesikhundla esibalulekile embonini yepulasitiki.
Ukuhlukaniswa kwe-PE
Ngenxa yezinqubo ezahlukene ze-polymerization ze-polyethylene, isakhiwo sayo sihlukile, futhi izakhiwo zomkhiqizo ezihambisanayo nazo zihluke kakhulu.Ikakhulukazi ingahlukaniswa: I-Low-Density Polyethylene (LDPE), Linear Low Density Polyethylene(LLDPE), High-Density Polyethylene(HDPE).
I-LDPE: Isetshenziselwa ikakhulukazi iphepha lokwenziwa, ifilimu yezolimo, ifilimu yokupakishwa kwezimboni, ucingo, njll;
I-LLDPE: Isetshenziselwa kakhulu izintambo nezintambo, amapayipi, izidingo zansuku zonke, njll;
I-HDPE: Isetshenziselwa ikakhulukazi izintambo, izintambo, amanetha okudoba, njll.
Ukusatshalaliswa kwamandla okukhiqiza e-PE ngezwe
Kusukela ngo-Ephreli 2022, umthamo wokukhiqiza we-PE waseChina usufinyelele amathani angaba yizigidi ezingama-29.18, okubalelwa ku-21% wawo wonke amandla okukhiqiza e-PE emhlabeni.Kungabonakala kudatha yokuthi umthamo wokukhiqiza we-PE womhlaba wonke ugxile kakhulu e-China, e-United States nase-Saudi Arabia.I-China njengamanje iyizwe elinamandla amakhulu okukhiqiza i-polyethylene emhlabeni.
Liyini i-PE coated paper?
Sesivele sinokuqonda okujulile kwe-PE ngenhla, ngakho-ke liyini iphepha elihlanganiswe ne-PE?Kalula nje, iphepha elihlanganisiwe le-PE liyinhlanganisela eyenziwe ngephepha njengento eyisisekelo futhi ehlanganiswe nongqimba lwefilimu ye-polyethylene ephepheni lesisekelo, okungukuthi, izinhlayiya zepulasitiki zimbozwe phezu kwephepha ngomshini wokuphonsa.Iphepha lilula ukumanzisa, kodwa ngemva kokuhlanganiswa ngokuphelele ne-polyethylene, iphepha eliboshwe lingakwazi ukufeza imiphumela yokungangeni kwamanzi, uwoyela-ubufakazi kanye nokushisa okuphezulu.
Ukuhlukaniswa kwephepha eliboshwe nge-PE
Ngokomehluko phakathi kwenombolo yefilimu enandisiwe, ingahlukaniswa ibe yiphepha elinohlangothi olulodwa lwe-PE, iphepha elinezinhlangothi ezimbili le-PEcoated, kanye ne-interlayer PE ehlanganiswe nephepha.
1. Iphepha eliboshwe nge-PE enohlangothi olulodwa
Iphepha le-PEcoated elinohlangothi olulodwa limbozwe ngefilimu ye-PE ohlangothini olulodwa lwephepha lesisekelo.Isetshenziswa ezinkomishini zephepha zokuphuza ezishisayo, iphepha le-hamburger, njll.
2. Iphepha elinamahlangothi amabili e-PE
Iphepha elinezinhlangothi ezimbili le-PE elimbozwe nge-PE ezinhlangothini zombili zephepha lesisekelo.Isetshenziswa ezinkomishini zephepha zokuphuza ezibandayo.
Iphepha elihlanganiswe ne-Interlayer
Iphepha eliboshwe ngesamishi ukufaka i-PE enamathelayo phakathi kwamaphepha amabili esisekelo ukuze kuhlanganiswe ucezu olulodwa lwephepha ukuze kuthuthukiswe ukuguquguquka kwephepha.
Okuvame ukusetshenziswa ku: ukupakishwa kwe-desiccant, izikhwama zokupakisha ukudla, njll.
Ngokusho kwezingubo ezihlukene, zingahlukaniswa zibe izinhlobo ezimbili: ifilimu ekhanyayo kanye nefilimu encane.
Ifilimu ekhanyayo yifilimu ye-polyethylene esobala enamacala amabili enendawo ekhanyayo nesandla esibushelelezi.Ifilimu ye-matte ifilimu ye-matte polyethylene enefilimu ye-matte enenkungu.
Ama-sequin anencazelo ephezulu futhi indaba ephrintiwe inemibala eminingi.Amafilimu ama-matte athuliswe kakhulu ngombala.
Ukusetshenziswa kwephepha eliboshwe
Iphepha elihlanganisiwe lihlobene eduze nempilo yethu yansuku zonke futhi linokusetshenziswa okubanzi, ikakhulukazi okusetshenziselwa ukupakisha, ukudla, ukwelashwa, i-electronics, i-hardware, i-die cutting, njll.
Ububanzi besicelo sephepha elihlanganisiwe:
Ububanzi bokusetshenziswa kwephepha eliboshwe
1. Amakhemikhali: ukupakishwa kwe-desiccant, ama-mothballs, i-powder yokuwasha, ama-preservatives.
2. Ukudla: izinyanda zenoodle, ukupakishwa kuka-ayisikhilimu, ubisi.
