Nigute PVDC inzitizi ndende ibicuruzwa byoroshye gupakira bikoreshwa?Igice cya 1

1 、 Imikorere no gushyira mu bikorwa PVDC:
Inganda mpuzamahanga za pulasitike zikoreshwa mu gukoresha ubwinshi bwumubiri bwokwemerera kwerekana itandukaniro ryimikorere nibikoresho bifite umwuka wa ogisijeni uri munsi ya 10 byitwaibikoresho byo hejuru.10 ~ 100 bita ibikoresho byo hagati.Kurenga 100 byitwa ibikoresho bisanzwe.Kugeza ubu, batatu baramenyekanyeibikoresho byo hejurukwisi ni PVDC, EVOH na PAN.Ibikoresho bitatu byose ni kopi.Inzitizi ya ogisijeni ya EVOH iruta iya PVDC naho iya PVDC iruta iya PAN;Kuri bariyeri y'amazi, EVOH iruta PVDC, naho PVDC iruta PAN.Nyamara, mugihe cy'ubushyuhe bwinshi, imiterere ya molekile ya EVOH irimo - OH itsinda, ryoroshye cyane gukuramo ubuhehere, kandi imikorere ya bariyeri izagabanuka cyane.Muri icyo gihe, imikorere ya barrière yibikoresho bya PAN nayo iragabanuka cyane hamwe no kwiyongera kwubushuhe bwibidukikije.PVDC ninzitizi nziza yuzuye ya barrière yaibikoresho byo gupakiramw'isi.

Polyvinylidene chloride resin (PVDC) ni copolymer hamwe na vinylidene chloride monomer nkibice byingenzi.Nibikoresho byiza byo gupakira hamwe na bariyeri ndende, gukomera gukomeye, kugabanuka kwamashyanyarazi no gutuza imiti hamwe nibyiza byo gucapa no gufunga ubushyuhe.Ikoreshwa cyane mubiribwa, ubuvuzi, igisirikare nizindi nzego.

Gutezimbere cyane ibicuruzwa bya PVDC bifite ubuhanga buhanitse bifite akamaro kanini kuringaniza umutungo wa chlorine munganda za chlor-alkali kandi bitezimbere cyane imikorere yimishinga no guhangana.PVDC ifite imitungo myiza ya barrière nkibikoresho byo gupakira.Gukoresha PVDC mugupakira ibiryo birashobora kongera igihe cyubuzima, kandi mugihe kimwe, bigira ingaruka nziza zo kurinda ibara, impumuro nuburyohe bwibiryo.Ibikoresho bya PVDC bifite ibikoresho bike byo gukoresha umutungo ugereranije na firime isanzwe ya PE, impapuro, ibiti,aluminiumn'ibindi bikoresho byo gupakira.Ingano yimyanda yo gupakira yagabanutse cyane kandi igiciro cyose cyaragabanutse, kugirango tugere ku ntego yo kugabanya ibicuruzwa.

PVDC ikoreshwa cyane mu bihugu by’iburengerazuba, irimo ibiryo, imiti, amavuta yo kwisiga, imiti, ibikoresho n’ibikoresho bya mashini, kandi bizwi nkibikoresho byo gupakira “icyatsi”.Ikoreshwa rya PVDC rifitanye isano n'imibereho y'igihugu.Kugeza ubu, PVDC ikoreshwa buri mwaka ni toni 50000 muri Amerika & toni 45000 mu Burayi, hamwe na toni 40000 muri Aziya na Ositaraliya.Ikigereranyo cy'ubwiyongere bw'umwaka cyo gukoresha isoko rya PVDC mu Burayi, Amerika n'Ubuyapani ni 10%.Muri Amerika, toni zirenga 15000 za resin ya PVDC zikoreshwagupakiraby'ibice binini by'inyama nshya buri mwaka, hamwe no gukoresha igipapuro cya PVDC ku mpapuro zingana na 40% by'ibikoreshwa byose bya PVDC.Mu Buyapani no muri Koreya yepfo, umubare munini wibikoresho byo gupakira PVDC bikoreshwa mubiribwa, ubuvuzi, ibikomoka ku miti nibikoresho bya elegitoroniki bipakira.Buri mwaka ikoreshwa rya resin ya PVDC irenga toni 10000 kuri firime ya plastike gusa.
