1. Kuita uye kushandiswa kwePVDC:
Indasitiri yepurasitiki yepasirese inoshandiswa kushandisa huwandu hwemuviri hwekugonesa kuratidza mutsauko mukuita uye zvinhu zvine oxygen permeability pazasi gumi zvinodaidzwa.yakakwirira chipingamupinyi zvinhu.10 ~ 100 inonzi medium barrier materials.Zvinopfuura 100 zvinonzi zvakajairika barrier material.Parizvino, vatatu vakazivayakakwirira chipingamupinyi zvinhumunyika mune PVDC, EVOH nePAN.Izvo zvinhu zvitatu zvese copolymers.Iyo oxygen barriers yeEVOH iri nani pane yePVDC uye iyo yePVDC iri nani pane yePAN;Pakuvharira mhute yemvura, EVOH iri nani pane PVDC, uye PVDC iri nani pane PAN.Zvisinei, pasi pemamiriro ehunyoro hwepamusoro, EVOH molecular structure ine - OH boka, iro riri nyore kwazvo kutora unyoro, uye kushanda kwayo kwekudzivirira kuchaderedzwa zvakanyanya.Panguva imwecheteyo, iyo yekuvharira kuita kwePAN zvinhu zvakare yakaderedzwa zvakanyanya nekuwedzera kwehunyoro hwemamiriro ekunze.PVDC ndiyo yakanakisa yakazara chipingamupinyi kuita kweepurasitiki kurongedza zvinhumunyika.
Polyvinylidene chloride resin (PVDC) icopolymer ine vinylidene chloride monomer sechikamu chikuru.Iyo yakanaka yekurongedza zvinhu ine yakakwirira chipingamupinyi, kusimba kwakasimba, yakanakisa yekupisa shrinkage uye kugadzikana kwemakemikari uye yakanakisa kudhinda uye kupisa-kuvhara zvivakwa.Inoshandiswa zvakanyanya mukudya, mishonga, mauto uye mamwe minda.
Kushingairira kugadzira zvigadzirwa zvePVDC zvine tekinoroji yepamusoro zvakakosha kuenzanisa zviwanikwa zvechlorine muindasitiri yechlor-alkali uye kunatsiridza zvakanyanya kushanda zvakanaka kwebhizinesi uye kukwikwidza.PVDC ine yakanakisa chipingamupinyi chivakwa sechinhu chekurongedza.Kushandisa PVDC kurongedza chikafu kunogona kuwedzera hupenyu hwesherufu zvakanyanya, uye panguva imwe chete, ine yakanakisa kudzivirira paruvara, kunhuwa uye kuravira kwechikafu.PVDC composite packaging ine yakaderera unit sosi yekushandisa pane yakajairwa PE firimu, bepa, huni,aluminium foilnezvimwe zvekurongedza zvinhu.Huwandu hwemarara ekurongedza hwakadzikiswa zvakanyanya uye mutengo wakaderedzwa, kuitira kuti uwane chinangwa chekudzikisa kurongedza.
PVDC inoshandiswa zvakanyanya munyika dzekumavirira, inosanganisira chikafu, makemikari, zvizorwa, mishonga, hardware uye mechanical zvigadzirwa, uye inozivikanwa se "girinhi" packaging materials.Iko kushandiswa kwePVDC kune hukama nehupenyu hwenyika.Parizvino, kushandiswa kwepagore kwePVDC kunosvika 50000 matani muAmerica & 45000 matani muEurope, uye huwandu hunosvika 40000 matani muAsia neAustralia.Avhareji yekukura kwepagore kwePVDC kushandiswa kwemusika muEurope, America neJapan i10%.Munyika dzeAmerica, matani anopfuura 15000 ePVDC resin anoshandiswavacuum packagingyezvimedu zvihombe zvenyama itsva gore negore, uye kudyiwa kwePVDC kupfeka pamapepa kunopa 40% yehuwandu hwekudyiwa kwePVDC.MuJapan neSouth Korea, nhamba huru yePVDC yekurongedza zvinhu zvinoshandiswa mukudya, mushonga, zvigadzirwa zvemakemikari uye zvigadzirwa zvemagetsi zvekurongedza zvinhu.Kushandiswa kwepagore kwePVDC resin kunodarika 10000 matani chete kwefirimu repurasitiki.
