Ingaba iPVDC ephezulu isithintelo ebhetyebhetye iimveliso zokupakisha isebenza njani?Icandelo loku-1

1. Ukusebenza kunye nokusetyenziswa kwePVDC:
Imboni yeplastiki yamazwe ngamazwe isetyenziselwa ukusebenzisa ubungakanani bomzimba obubonakalayo ukubonisa umahluko ekusebenzeni kunye nezixhobo ezine-oxygen permeability ngaphantsi kwe-10 zibizwa.izixhobo zomqobo ophezulu.I-10 ~ 100 ibizwa ngokuba yimathiriyeli yomqobo ophakathi.Ngaphezulu kwe-100 kuthiwa yimathiriyeli eqhelekileyo yomqobo.Okwangoku, abathathu babonileizixhobo zomqobo ophezuluehlabathini ziiPVDC, EVOH kunye nePAN.Ezi zinto zintathu zonke zi-copolymers.Umqobo we-oksijini we-EVOH ungcono kune-PVDC kwaye i-PVDC ingcono kune-PAN;Ngokuthintela umphunga wamanzi, i-EVOH ingcono kune-PVDC, kwaye i-PVDC ingcono kune-PAN.Nangona kunjalo, phantsi kweemeko zomswakama ophezulu, i-EVOH i-molecular structure iqulethe - iqela le-OH, elilula kakhulu ukufumana umswakama, kunye nokusebenza komqobo walo kuya kuncitshiswa kakhulu.Kwangaxeshanye, ukusebenza komqobo wezinto zePAN kukwancipha kakhulu ngokunyuka kokufuma kokusingqongileyo.I-PVDC yeyona ndlela igqwesileyo yomqobo osebenza ngayoizinto zokupakisha zeplastikiemhlabeni.

I-Polyvinylidene chloride resin (PVDC) yi-copolymer ene-vinylidene chloride monomer njengeyona nto iphambili.Yimpahla yokupakisha efanelekileyo kunye nomqobo ophezulu, ukuqina olomeleleyo, i-shrinkage egqwesileyo ye-thermal kunye nokuzinza kweekhemikhali kunye nokuprinta okugqwesileyo kunye nokutywinwa kobushushu.Isetyenziswa kakhulu ekutyeni, kumayeza, emkhosini nakwamanye amasimi.

Ukuphuhlisa ngokusebenzayo iimveliso ze-PVDC ezinomxholo ophezulu weteknoloji kubaluleke kakhulu ukulungelelanisa izibonelelo zeklorine kwishishini le-chlor-alkali kunye nokuphucula kakhulu ukusebenza kakuhle kweshishini kunye nokhuphiswano.I-PVDC inepropathi egqwesileyo yomqobo njengento yokupakisha.Ukusebenzisa i-PVDC ukupakisha ukutya kunokwandisa kakhulu ubomi beshelufu, kwaye kwangaxeshanye, kunempembelelo ebalaseleyo yokukhusela kumbala, ivumba kunye nencasa yokutya.Ipakethe ehlanganisiweyo ye-PVDC inosetyenziso olusezantsi lwesixhobo kunefilimu ye-PE eqhelekileyo, iphepha, iinkuni,ifoyile yealuminiyamkunye nezinye izinto zokupakisha.Umthamo wenkunkuma yokupakishwa uncitshiswe kakhulu kwaye ixabiso lilonke liye lancitshiswa, ukuze kuphunyezwe injongo yokunciphisa ukupakisha.

I-PVDC isetyenziswa kakhulu kumazwe asentshona, ebandakanya ukutya, iikhemikhali, izithambiso, amayeza, i-hardware kunye neemveliso zoomatshini, kwaye yaziwa ngokuba yizinto zokupakisha “eziluhlaza”.Ukusetyenziswa kwePVDC kunxulumene nomgangatho wokuphila wesizwe.Okwangoku, ukusetyenziswa konyaka kwe-PVDC malunga neetoni ezingama-50000 eMelika kunye neetoni ezingama-45000 eYurophu, kunye neetoni ezimalunga ne-40000 e-Asiya nase-Australia.Umyinge wokukhula ngonyaka wokusetyenziswa kweemarike zePVDC eYurophu, eMelika naseJapan yi-10%.EMelika, ngaphezu kwe-15000 yeetoni ze-PVDC resin zisetyenziselwaukupakishwa kwevacuumAmaqhekeza amakhulu enyama entsha ngonyaka, kwaye ukusetyenziswa kwePVDC yokwambathisa ephepheni kubalelwa kwi-40% yokusetyenziswa iyonke yePVDC.EJapan naseMzantsi Korea, inani elikhulu lezinto zokupakisha ze-PVDC zisetyenziselwa ukutya, amayeza, iimveliso zekhemikhali kunye neemveliso zombane zokupakisha izinto.Ukusetyenziswa konyaka kwe-PVDC resin kungaphezu kweetoni ze-10000 kuphela kwifilimu yeplastiki.
