Ukwenzela ukwandisa ubomi beshelufa yezinto ezinjengokutya nakwiziyobisi, ezininziIzinto zokupakishaUkutya kunye neziyobisi kule mihla isebenzisa iifilimu ezahlukeneyo zokupakisha iifilimu. Okwangoku, zimbini, ezintathu, ezintlanu, ezisixhenxe, ezisixhenxe, ezithoba, kunye nee-eleen ezikwimigangatho yokupakisha. Ifilimu yephakheji ye-Wiceking yePhambili yifilimu ecekeceke yenziwa ngokukhupha izixhobo ezininzi zeplastiki ngaxeshanye ukusuka ekuvulekeni kwawo ngaxeshanye ukuvulwa kwemvula enye, enokunyusa izibonelelo zezixhobo ezahlukeneyo
Ubuninzi bamandlaukupakisha ifilimuzibunjwe ikakhulu yi-Polyoolefin. Okwangoku, izakhiwo eziqhelekileyo ezisetyenzisiweyo zibandakanya: Polythyylene / Polythylene, iPolythylene i-vinyane ye-vinyane, i-polyproplene ye-vinyae, i-ldpe / i-ideh / i-evh / i-evh / i-evhlo / i-feed / i-ideh Ubungqingqwa bomaleko ngamnye bunokuhlengahlengiswa ngetekhnoloji yokuphuma. Ngokuhlengahlengisa ubukhulu bomqobo wokungaqhelekanga kwaye usebenzisa izixhobo ezahlukeneyo zothintelo, iifilimu eziguquguqukayo ezinepropathi yomqobo eyahlukeneyo inokwenziwa. Izinto zokuthengisa izinto zokuthengisa zinokutshintshwa kwaye zihlengahlengiswe ukuze zifezekise iimfuno zepakeji ezahlukeneyo. Le ndlela yokuhambahamba kwezinto ezininzi kunye nepakethi ye-Pultifoulting yesona sikhokelo siphambili kuphuhliso lwezinto zePasika kwixesha elizayo.
Isakhiwo sefilimu ye-Multi
Ifilimu yefilimu emininzi yokupakisha, ngaphandle kwenani leengcambu, lihlulwe lubambisene lwahlulwe lubambiso, ungqimba olusebenzayo, kunye nokunamathela ngokusekwe kumsebenzi ngamnye wefilimu.
Inqanaba elisisiseko
Ngokubanzi, iindawo ezingaphakathi nezangaphandle zeefilimu ezihlanganisiweyo kufuneka zibe neepropathi ezifanelekileyo zomzimba kunye noomatshini, ukwenza umsebenzi wokuqhubela phambili, kunye ne-heather yokutywina. Ikwafuna ukuba nentsebenzo evuthayo ye-sub yokutywina kunye nokusebenza kwe-welding ye-welding, eneendleko eziphantsi, zinenkxaso elungileyo kunye nokugcinwa kwezinto kwifilimu esebenzayo, kuchonga ubungqola befibalamo. Izinto ezisisiseko ze-PE, i-PP, eva, i-Eva, Pet, ne-PS.
Ungqameko
Ungqimba olusebenzayo lweIfilimu yokupakisha ukutyaUbukhulu becala ungqwayitha, ihlala imbindini yefilimu yokudibanisa amaqela amaninzi, ubukhulu becala usebenzisa i-InOH, iPVDC, i-PVDC, i-PVDC, i-PVDC, kunye ne-PETDC yePropathi yeZithintelo, ikwizixhobo ezifanayo.
I-EvOH (E-Ithone Vinyl Copolymer)
I-Ethylene Vinyl Copolymer Copolymer i-polymer edibanisa ukwenziwa kweepolitiki ze-Ethylene kunye nePropathi yeRists ye-polly ye-polymers. Ibonakala kakhulu kakhulu kwaye ine-gloss elungileyo. I-EGOH ineepropathi ezigqwesileyo zeegesi kunye neoyile, ngamandla amakhulu oomatshini, amashumi alastity, ukunxiba ukunganyangeki, amandla okubanda, kunye nokusebenza komgangatho, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu, kunye nokusebenza okungaphezulu. Ukusebenza kwesithintelo kwe-EDOH kuxhomekeke kumxholo we-Ethylene. Xa umxholo we-Ethyylene usonyuka, igesi yomqobo yokusebenza iyancipha, kodwa ukusebenza kokuthantamisa ukufuma kuyanda, kwaye kulula ukuyiqhubela phambili.
Iimveliso ezifakwe kwi-EVEOSOSS zibandakanya izixhobo, iimveliso zobisi, iimveliso zenyama, iimveliso zetshizi, njl.
I-PVDC (Polyvinylidene Chloride)
I-Polyvinylidene Chloride (PVDC) yi-polymer ye-vinylidene chloride (1,1-dichlorookenene). Iqondo lokushisa le-Homollymer pvdc lingaphantsi kwendawo yayo yokunyibilika, yenze kube nzima ukunyibilika. Ke ngoko, njengezinto zokupakisha, i-PVDC yi-copolyne chloridene i-chloride kunye ne-vinyl chloride, enokuchasana kakuhle, ukuxhathisa okuhle, ukushicilela kunye nokushicilela kunye nokushicilela okuhle kunye nokuprinta.
Kwiintsuku zokuqala, yayisetyenziselwa ukupakisha emkhosini. Kwiminyaka yee-1950s, yaqala ukusetyenziswa njengefilimu yokulondolozwa kokutya, ngakumbi kuphuhliso olukhawulezileyo lwetekhnoloji yale mihla kunye nobomi bexesha lokulondolozwa kunye nokulondolozwa kwe-microwave kukhuseleko lwe-PVDC. I-PVDC inokwenziwa kwiifilimu ze-Ultra, ukunciphisa isixa sezinto ezingafunekiyo kunye neendleko zokupakisha. Isathandwa namhlanje
Umaleko wobumbeleleyo
Ngenxa yobunyani obuhlwempuzekileyo phakathi kwezinye izinto ezisisiseko kunye ne-therter esebenzayo, iyimfuneko ukubeka amanye amalungu onamathela phakathi kwezi zixhobo zine-glue kwaye zenze ifilimu edibeneyo. I-Adesies Onetiver isebenzisa i-Desing Desing, isetyenziswa ngokuqhelekileyo kubandakanya i-Polyoolefin ye-Annehyride kunye ne-Ethylene Vinyl Acetate Copolymer Copolymer.
I-anmehydride ye-annehyride ye-Polyoolefins
I-Polynolefide ye-Adydride ye-Polyoolefini iveliswa yi-GofDride ye-Anhhydride kwi-Polythylene ngokusebenza kwakhona, yazisa amaqela asemacaleni akwi-polar. Kukumbetha phakathi kwezixhobo ze-Polar kunye ne-polar kwaye zihlala zisetyenziswa kwiifilimu ze-Polyoolefins ezinje ngePolypropylene kunye ne-NYLOLO.
I-Eva (i-Ethonene Vinyl Acetate Copolymer)
U-Eva wazisa i-vinyl acetate monomer kwi-moleculate thein, ukunciphisa i-crystalliety ye-polythylene kunye nokuphucula ukuntywila kunye nokutywina kwe-filr. Imixholo eyahlukeneyo ye-Ethylene kunye neVinyl i-vinyl ye-SOFS kwizicelo ezahlukeneyo:
① Iimveliso eziphambili ze-Eva kunye ne-ithylene i-Ethylene ingezantsi kwe-5% zinamadyole, iifilimu, iingcingo kunye neentambo, njl.
② Iimveliso eziphambili ze-Eva kunye ne-vinyl acetate yomxholo we-5% ~ 10% ziifilimu ze-elastic, njl.
③ Iimveliso eziphambili ze-EVA nge-vinyl ye-vinyl ye-vinyl ye-20% ~ 28% ishushu inyibilikisi imililo kunye neemveliso ezihlekisayo;
④ Iimveliso eziphambili ze-EVA nge-vinyl acetate yemixholo ye-5% ~ 45% ziifilimu (kubandakanya iifilimu zezolimo) kunye neemveliso ezifakelweyo, iimveliso zempundu, njl.
