Amaphuzu olwazibheka i-MODPE
1, ifilimu ye-MDOPE,okungukuthi, inqubo ye-MDO (unidirectional stretch) ekhiqizwa yifilimu ye-PE substrate ye-polyethylene eqinile kakhulu, enokuqina okuhle kakhulu, ukucaca, ukumelana nokubhoboza kanye nokumelana nokushisa, izici zayo zokubukeka kanye nefilimu ye-BOPET ifana kakhulu nekhono lokufeza i-PE ne-PE composite, ngaleyo ndlela idala u-100% wokwakheka kwezinto ze-polyethylene zokupakisha okuguquguqukayo ekusetshenzisweni kabusha akudingeki ukuthi kukhishwe amapulasitiki ahlukene, uma kusetshenziswa kabusha, asikho isidingo sokukhumula amapulasitiki ahlukene, okunciphisa kakhulu ubunzima benqubo. Lokhu kusungula izinto ezintsha kudlula imikhawulo yokupakisha okuguquguqukayo okuhlanganisiwe okwenziwe ngezinto eziningi ezahlukene ezingenakuphinde zisetshenziswe, futhi kuyisinyathelo esikhulu phambili kubuchwepheshe bokupakisha obuguquguqukayo.
Amafilimu e-MDOPE ahlukaniswe uchungechunge oluthathu:
Uchungechunge lohlobo olujwayelekile lwe-MDOPE-T,
Uchungechunge lwe-MDOPE-E olunezithiyo eziphakeme,
uchungechunge lwezithiyo eziphakeme kakhulu ze-MDOPE-S;
Ngenxa yokuthi ithambile futhi isebenza kahle ekuphrinteni, ukuzinza okuhle kakhulu kokushisa kanye nokuncipha okuphansi, ifilimu ye-MDOPE manje ingasetshenziswa njengefilimu yokuphrinta yezikhwama zokuvala ezinezinhlangothi eziyisishiyagalombili, izikhwama zomlomo zokumunca kanye nezikhwama ze-zipper.
2. Isitifiketi se-GRS simelela i-Global Recycled Standard.
Kuyindinganiso yomhlaba wonke, yokuzithandela, yomkhiqizo wonke eyenzelwe ukuqinisekisa ukuthi okuqukethwe okuphinde kwasetshenziswa kwemikhiqizo kubhalwe ngokunembile, nokuqinisekisa ukuthi imikhiqizo ikhiqizwa ngokuhambisana nezindinganiso ezithile zemvelo kanye nomthwalo wemfanelo wezenhlalo.
Kuyindinganiso yomhlaba wonke, yokuzithandela, yomkhiqizo wonke eyenzelwe ukuqinisekisa ukuthi okuqukethwe okuphinde kwasetshenziswa kwemikhiqizo kubhalwe ngokunembile nokuthi inqubo yokukhiqiza ihlangabezana nezindinganiso ezithile zomthwalo wemfanelo kwezemvelo kanye nomphakathi.
I-GRSPE (ene-pe ephinde yasetshenziswa)
Kusukela ngo-2022, iShanghai Xiangwei Packaging Co., Ltd ibilokhu yenza ucwaningo ngokunyatheliswa kwezikhwama ezingasetshenziswa kabusha, futhi siqoqe ulwazi oluningi kanye nesikhundla esivuthiwe nesihamba phambili embonini ekusetshenzisweni kwazo.
Ubunzima obukhulu bezinto ezisetshenziswayo zodwa buvela ekwenzeni izikhwama, okudinga ukubambisana kwezinqubo ezilandelayo. Izinto ze-MDOPE zidinga ukuba nomehluko othile wokushisa nefilimu eyisisekelo ukuze kuqiniswe ukwenziwa kwezikhwama.
Ngokuphathelene nokuphrinta, kudingeka kuqashelwe ukuphrinta ngokweqile, ukunamathela kuyinki, umphumela wokomisa (insalela kanye nokunamathela). Ukulingana kwezinto kanye nokulawula ukucindezeleka.
Esihlanganisweni, isidingo esifanayo sokulawula ukungezwani, izinga lokushisa lokomisa, ukomisa ivolumu yomoya enkulu ngangokunokwenzeka, ukusetshenziswa kwenqubo yokugoqa enetha engajulile ephezulu kungcono.
Ukwenza izikhwama kuyisinyathelo esibalulekile, ukwenza izikhwama ngommese wokuvala ukushisa ukuze kwenziwe ukwelashwa okunganamatheli, zama ukukhiqiza izinga lokushisa eliphansi kanye nemodi yokucindezela okuphezulu;
Uma sithenga izinto zokwakha, kufanele siqinisekise ukuthi indawo yomehluko wokushisa yendawo yokuncibilika kokushisa kwendwangu nezinto eziyisisekelo kufanele ibe nkulu;
Lawula ukucindezeleka kokudonsa izinto lapho wenza izikhwama, uma zincane kungcono;
Beka uhlangothi olubanzi ngangokunokwenzeka njengohlangothi oluqondile, uma isikhwama sincane, senza imigqa eminingi ngangokunokwenzeka, ukuze kugwenywe ukuhamba, ifilimu yezinto ezibonakalayo incane kakhulu;
Yenza izikhwama ze-zipper uma ukhetha i-zipper ekhethekile enokushisa okuphansi, ukuze ugweme ukuqhuma kwekhanda le-zipper.
Njengamanje, imboni ngokuvamile ikholelwa ukuthi ukumelana nokushisa kwefilimu ye-MDOPE kuhle, uhlobo lwesikhwama luyisicaba kakhulu, kulula ukulawula ukugoba.
Izinto ze-PE zokufakwa ngaphakathi kumele zikhethwe ngokwesimo esithile, isibonelo, uma udinga izakhiwo ezinhle zokuvimbela, ungakhetha i-EVOH-PE noma i-PE enobisi.
Uma kungekho mfuneko ekhethekile, ungakhetha i-LDPE evame ukusetshenziswa！
IYELULEKISA
1. Zama ukushaya umugqa odambisa kalula uma izindleko zekhasimende ziwusekela.
2. Ngaphambi kokwamukela i-oda (ngokwezinhlobo ezahlukene zezikhwama), kuchazwa ukuthi isakhiwo se-PE//PE sokuqina komzimba wesikhwama sibi kakhulu kunezinye izinto (ungathatha ividiyo yakamuva yohlobo lwesikhwama olufanayo ukuchaza!) Umzimba wesakhiwo se-PE//PE awusicaba kangako kunezinye izinto (ungathatha ividiyo yakamuva yezikhwama ezifanayo ukuze ubonise!)
Ukupakisha okungasetshenziswa kabusha kwezinto ezilodwa ngokuqinisekile kuyisitayela, amabhizinisi okunyathelisa imibala ukwenza umsebenzi omuhle wemithombo yobuchwepheshe kuyimfuneko, kutuswa ukuthi uzame izindawo ezimbili ezilandelayo kuqala:
1、Ukupakisha Okuqandisiwe
Sebenzisa i-PE yokudonsa okukodwa esikhundleni se-PET ne-BOPA ye-nylon ukukhiqiza izinto ze-PE eyodwa zokupakisha ifriji, ikakhulukazi ekupakisheni ifriji okungadingi ukusebenza okuphezulu kokuvimbela.
I-PE esikhundleni se-nylon, ekwenqabeni kokubhoboza, ukumelana nokudabuka kuzoncishiswa, kodwa kungahlangabezana nezidingo zokupakisha okuqandisiwe, ngoba amakhasimende amaningi angacabangela ukuphindaphinda. Uma i-PE isetshenziswa esikhundleni se-PET, ukwenyuka kwezindleko kuzoba phezulu. Sekukonke, uma isikhwama sikhulu, izindleko zokufaka esinye ziphakeme impela.
2、Imikhiqizo yokushisa evamile kanye nokulondolozwa kwesikhathi esifushane
Ibhizinisi lokuphrinta imibala lingaqala kusukela ekushiseni kwegumbi, ekupakisheni umkhiqizo okufushane, kuqala ngokujwayelana nezinto kanye nenqubo, lilinde ukuthi izinto zivuthwe kakhulu.
Ngesikhathi esifanayo, maqondana nenqubo, kufanele futhi unake:
Ukukhiqizwa kokupakisha izinto ezilodwa, kulapho izinto eziguquguqukayo ezimbalwa ziba ngcono khona.
Isibonelo, ukupakisha kwe-xiangwei. Ukuphrinta komshini wokunyathelisa okukhethekile kwe-PE, umphumela muhle kakhulu, ukungezwani kungalawulwa kahle kakhulu, ukuphrinta ngokweqile kunembe kakhulu, kungakhathaliseki ukuthi ukuphakamisa nokwehlisa ijubane noma ukushintsha umqulu, kungalawulwa kahle kakhulu. Ikhwalithi yokunyathelisa nge-DIC iyinki ye-DIC isondele ngo-97% ezingeni lokunyathelisa nge-nylon.
Ngakho-ke, ekukhiqizweni kokupakisha kwezinto ezingasetshenziswa kabusha, zama ukucacisa imishini okufanele ikhetheke ekukhiqizeni, ungashintshi umugqa wokukhiqiza ngokungenanjongo ukuqinisekisa ukuzinza kwenqubo nokukhulisa ukulawula kokulahlekelwa. Isibonelo, izinto ze-PE ekwenzeni izikhwama, nezinye izinto zihlukile ngokuyisisekelo. Kulokhu esikhundleni sokuvumela izinto ukuthi zivumelane nomshini wokwenza izikhwama, kunokuvumela umshini wokwenza izikhwama ukuthi uzivumelanise nezinto: uma ku-batch ye-PE ukuzama kanye nomshini, khona-ke ukusebenza kahle kuphansi kakhulu. Ngokuphambene nalokho, ikakhulukazi ucwaningo lokupakisha izinto ze-PE olulodwa kanye nokuthuthukiswa komshini wokwenza izikhwama, kufaka phakathi ingcindezi yokuvala ukushisa, inani lokulawula izinga lokushisa lokuvala ukushisa, njll., kungalungiswa ngokufanele ukuze kugwenywe into yokuvala eshisa kakhulu noma engamanga.
