Amanqaku olwazijonga iMODPE
1, ifilimu ye-MDOPE,Oko kukuthi, inkqubo ye-MDO (ukwelula okulinganayo) eveliswa yifilimu ye-PE substrate polyethylene eqinileyo, enobulukhuni obugqwesileyo, ukucaca, ukumelana nokubhoboza kunye nokumelana nobushushu, iimpawu zayo zokubonakala kunye nefilimu ye-BOPET ifana kakhulu nokukwazi ukwenza i-PE kunye ne-PE composite, ngaloo ndlela idala i-100% yesakhiwo sezinto ze-polyethylene zokupakisha okuguquguqukayo ekusetyenzisweni kwakhona akufuneki zikhuphe iiplastiki ezahlukeneyo, Xa kusetyenzwa kwakhona, akukho mfuneko yokukhupha iiplastiki ezahlukeneyo, nto leyo enciphisa kakhulu ubunzima benkqubo. Olu tshintsho lugqitha imida yokupakisha okuguquguqukayo okudityanisiweyo okwenziwe ngezinto ezininzi ezahlukeneyo ezingenakuphinda zisetyenziswe, kwaye linyathelo elikhulu phambili kubuchwepheshe bokupakisha obuguquguqukayo.
Iifilimu zeMDOPE zahlulwe zibe ziichungechunge ezintathu:
Uthotho lohlobo oluqhelekileyo lwe-MDOPE-T,
uthotho lwe-MDOPE-E olunemiqobo ephezulu,
uthotho lwe-MDOPE-S olunemiqobo ephezulu kakhulu;
Ngenxa yokuba ithambile kwaye isebenza kakuhle ekuprinteni, uzinzo oluhle kakhulu kubushushu kunye nokuncitshiswa okuncinci, ifilimu ye-MDOPE ngoku ingasetyenziswa njengefilimu yokuprinta kwiingxowa zesitywino ezinamacala asibhozo, iingxowa zomlomo ezifunxayo kunye neengxowa ze-zipper.
2. Isatifikethi se-GRS simele iGlobal Recycled Standard.
Ngumgangatho wehlabathi, wokuzithandela, wemveliso epheleleyo owenzelwe ukuqinisekisa ukuba umxholo ophinda usetyenziswe weemveliso ubhalwe ngokuchanekileyo, kwaye uqinisekise ukuba iimveliso zenziwe ngokuhambelana nemigangatho ethile yoxanduva lokusingqongileyo kunye noluntu.
Ngumgangatho wehlabathi, wokuzithandela, wemveliso epheleleyo owenzelwe ukuqinisekisa ukuba umxholo ophinda usetyenziswe weemveliso ubhalwe ngokuchanekileyo kwaye inkqubo yemveliso ihlangabezana nemigangatho ethile yoxanduva lokusingqongileyo kunye noluntu.
I-GRSPE (ene-pe ephinde yasetyenziswa)
Ukususela ngo-2022, iShanghai Xiangwei Packaging Co., Ltd ibisenza uphando malunga nokuprintwa kweengxowa ze-mono-material ezinokuphinda zisetyenziswe, kwaye siqokelele amava amaninzi kunye nesikhundla esikhulileyo nesikhokelayo kushishino ekusetyenzisweni kwazo.
Eyona ngxaki iphambili yento enye ivela ekwenzeni iingxowa, nto leyo efuna intsebenziswano yeenkqubo ezilandelayo. Izinto ze-MDOPE kufuneka zibe nomahluko othile kubushushu kunye nefilimu esisiseko ukuze kuzinziswe ukwenziwa kweengxowa.
Ngokuphathelele ukuprinta, kufuneka kunikwe ingqalelo ekuprinteni kakhulu, ukunamathela kwiinki, isiphumo sokomisa (intsalela kunye nokunamathela). Ukulingana kwezinto kunye nolawulo lokuxinana.
Kwi-composite, imfuneko efanayo yokulawula uxinzelelo, ubushushu bokumisa, ukomisa umthamo womoya omkhulu kangangoko kunokwenzeka, ukusetyenziswa kweglue ephezulu enoxinano oluphezulu kunye nenkqubo yokuqengqeleka kwenethi engaphantsi kungcono.
Ukwenza iingxowa linyathelo eliphambili, ukwenza iingxowa kwimela yokutywina ubushushu ukwenza unyango olunganamatheliyo, zama ukwenza ubushushu obuphantsi kunye noxinzelelo oluphezulu;
Xa sithenga izinto, kufuneka siqinisekise ukuba indawo yomahluko wobushushu kwindawo yokunyibilika kobushushu yelaphu kunye nezinto ezisisiseko kufuneka ibe nkulu;
Lawula uxinzelelo lokutsala izinto xa usenza iingxowa, kokukhona zincinci kokukhona zingcono;
Beka icala elibanzi kangangoko kunokwenzeka njengelithe nkqo, ukuba ibhegi incinci yenza imigca emininzi kangangoko kunokwenzeka, ukuze ungahambi, ifilimu yezinto ezibonakalayo incinci kakhulu;
Yenza iingxowa ze-zipper xa ukhetha i-zipper ekhethekileyo enobushushu obuphantsi, ukuze uphephe ukuqhuma kwentloko ye-zipper.
Okwangoku, imboni ngokubanzi ikholelwa ukuba ukumelana nobushushu befilimu ye-MDOPE kulungile, uhlobo lwebhegi luthe tyaba ngakumbi, kulula ukulawula i-curl.
Izinto ze-PE ze-lining kufuneka zikhethwe ngokwemeko ethile, umzekelo, ukuba ufuna iimpawu ezintle zokuthintela, ungakhetha i-EVOH-PE okanye i-PE enobisi.
Ukuba akukho mfuneko ikhethekileyo, ungakhetha i-LDPE esetyenziswa rhoqo！
ICEBISO
1.Zama ukucima umgca xa iindleko zomthengi zikuxhasa.
2. Ngaphambi kokuba wamkele iodolo (ngokweentlobo ezahlukeneyo zeengxowa), kuchazwa ukuba ulwakhiwo lwe-PE//PE lomzimba wengxowa lubi kancinci kunezinye izinto (ungathabatha ividiyo yakutshanje yohlobo olufanayo lweengxowa ukuze uchaze!) Umzimba wesakhiwo se-PE//PE awusicaba kunezinye izinto (ungathabatha ividiyo yakutshanje yeengxowa ezifanayo ukuze ubonise!)
Ukupakisha okungasetyenziswa kwakhona kwezinto ezisetyenzisiweyo ngokuqinisekileyo yindlela eqhelekileyo, amashishini okushicilela imibala kufuneka enze umsebenzi olungileyo wokugcinwa kobugcisa, kucetyiswa ukuba uzame ezi ndawo zimbini zilandelayo kuqala:
1、Ukupakishwa okukhenkcezisiweyo
Sebenzisa i-PE yokutsala enye endaweni ye-PET kunye ne-BOPA yenylon ukuvelisa izinto ze-PE enye zokupakisha ifriji, ingakumbi kwiipakethe zefriji ezingadingi ukusebenza okuphezulu.
I-PE endaweni ye-nylon, xa isetyenziswa ekubhobozeni, iya kuncipha inkxwaleko, kodwa inokuhlangabezana neemfuno zokupakisha okukhenkcezisiweyo, kuba uninzi lwabathengi lunokucinga ngokuziphinda-phinda. Ukuba kusetyenziswa i-PE endaweni ye-PET, ukunyuka kweendleko kuya kuba phezulu. Ngokubanzi, okukhona ibhegi ityebile kokukhona ixabiso lokutshintshwa liphezulu ngokuqinisekileyo.
2、Iimveliso zobushushu obuqhelekileyo kunye nezokugcinwa kwexesha elifutshane
Ishishini lokuprinta imibala lingaqala ukusuka kubushushu begumbi, isiqinisekiso esifutshane sokupakisha imveliso, kuqala liqhelane nezinto kunye nenkqubo, lilinde ukuba izinto zivuthwe ngakumbi.
Kwangaxeshanye, ngokwenkqubo, kufuneka kuqwalaselwe oku kulandelayo:
Ukuveliswa kokupakisha izinto ezisetyenziswa kwizixhobo ezahlukeneyo, kokukhona izinto eziguquguqukayo zincinci, kokukhona zingcono.
Umzekelo, ukupakisha i-xiangwei. Umatshini wokuprinta okhethekileyo we-PE uprinta, isiphumo silungile kakhulu, uxinzelelo lunokulawulwa kakuhle kakhulu, ukuprinta ngaphezulu kuchanekile kakhulu, nokuba kukuphakamisa nokunciphisa isantya okanye ukutshintsha i-roll, kunokulawulwa kakuhle kakhulu. Umgangatho wokuprinta nge-inki ye-DIC usondele kwi-97% kwinqanaba lokuprinta kwe-nylon.
Ngoko ke, ekuveliseni izinto eziphinda zisetyenziswe, zama ukucacisa izixhobo ekufuneka zikhetheke kwimveliso, ungatshintshi umgca wemveliso ngokungacwangciswanga ukuqinisekisa uzinzo lwenkqubo kunye nokulawula ukulahleka okukhulu. Umzekelo, izinto ze-PE ekwenzeni iingxowa, kunye nezinye izinto zahlukile ngokusisiseko. Ngeli xesha endaweni yokuvumela izinto ukuba zivumelane nomatshini wokwenza iingxowa, endaweni yokuvumela umatshini wokwenza iingxowa ukuba uvumelane nezinto: ukuba uzame inqwaba ye-PE xa sele umatshini, ukusebenza kakuhle kuphantsi kakhulu. Ngokwahlukileyo koko, ngokukodwa uphando lokupakisha izinto ze-PE kunye nophuhliso lomatshini wokwenza iingxowa, kubandakanya uxinzelelo lokuvala ubushushu, ubungakanani bolawulo lobushushu bokuvala ubushushu, njl. njl., lunokulungiswa ngokufanelekileyo ukuze kuthintelwe ukwenzeka kokuvalwa okushushu kakhulu okanye okungamanga.
