Nigute PVDC inzitizi ndende ibicuruzwa byoroshye gupakira bikoreshwa?Igice cya 2

2 application Porogaramu yihariye ya PVDC yibumbiye mubushinwa:
Ubushinwa bwatangiye gukoresha PVDC resin kuva mu ntangiriro ya za 1980.Ubwa mbere, ivuka rya ham sausage ryinjije firime ya PVDC mubushinwa.Hanyuma amasosiyete y'Abashinwa yahagaritse gukumira Amerika n'Ubuyapani kuri iryo koranabuhanga maze ashyiraho ikoranabuhanga ryo gutunganya n'ibikoresho bya firime ya PVDC.Kubera ko ubukungu bw’igihugu cy’Ubushinwa bugenda bwiyongera ndetse n’iterambere ry’imibereho n’umuco n’umuco, urwego rwo gukenera gupakira narwo rugenda rwiyongera.Ibikoresho byinshi kandi bipfunyika bikoreshwa cyane mubice byose byubukungu bwigihugu ndetse nubuzima bwabaturage.PVDC ni umuyobozi mugushikirainzitizi ndendeimiterere igiciro cyiza nubushuhe bwizewe, ogisijeni nimbogamizi.

Kubera ko buriwese afite ubumenyi bwinshi kuri firime ya PVDC, hano tuzibanda kuburyo bwa tekiniki nimiterere ya firime ya PVDC.Filime ikomatanya ikora ibitagenda neza kuri buri kintu, itanga umukino wuzuye kubikorwa byayo byiza, kandi ifite ibiranga ikintu kimwe kidafite.Uburyo busanzwe bwa PVDC:

Ipitingi, yumye, idafite umusemburo, ushushe-ushonga, gufatanya, n'ibindi. Kugeza ubu, umusaruro wo mu gihugu wa firime ya PVDC igizwe ahanini nuburyo bwo gutwikira, uburyo bwumye, budafite umusemburo hamwe n’ubufatanye:

1) firime ya PVDC
Ipfunyika ya PVDC ikoreshwa hejuru yubutaka (OPP, PA, PE, PET, nibindi) kugirango ikore firime ikomatanya kunoza imikorere ya bariyeri ya substrate.Ibiranga imikorere:
Inzitizi nziza;Ubunini bwurwego rwa PVDC muri rusange ni 2 ~ 3um, hamwe nigiciro gito;Ntushobora kwihanganira guteka ubushyuhe bwo hejuru.

2) PVDC yometse kuri membrane
Igizwe na firime nyinshi imwe-imwe, kandi buri cyiciro gihujwe na afashe.Irashobora kugabanywamo:
Kuma (solvent) kumurika no kumurika ubusa.

Ibiranga imikorere:
A. Hamwe naimitungo miremire hamwe nuburyo bworoshye, irashobora kwongerwaho na BOPA, CPP, CPE, BOPP, BOPET, PVC nizindi firime (urugero, BOPP, PET, PA irashobora gukoreshwa nkigice cyo gucapa hanze, PE, CPP nizindi ngaruka nziza zo gufunga amashyuza zirashobora gukoreshwa nk'icyuma gifata ubushyuhe, ubushyuhe bwiza bwa PA burashobora gukoreshwa nkurwego rwo kurwanya puncture, naho PVDC irashobora gukoreshwa nkurwego rwa bariyeri kugirango ihagarike ogisijeni namazi).

B. Kurwanya ubushyuhe bwiza.Irashobora gukorwa mubushyuhe bwo hejuru hamwe nubushyuhe buke bwihanganira imiterere ya firime igizwe nubushyuhe bwa - 20 ℃ ~ 121 ℃;
Ibikoresho byiza byubukanishi nubushyuhe, bikwiranye nuburyo butandukanye bwo gupakira, gucapa amabara, kugarukira kuri firime imwe, hagati aho ubunini bwa buri cyiciro ntibushobora kuba buke cyane kandi umubare wibice bitagomba kuba byinshi (muri rusange ntabwo ari byinshi kurenza ibice 5).

3) PVDC igizwe nabantu benshi bafatanije gukuramo firime
Amashanyarazi atandukanye asohorwa nabantu benshi icyarimwe icyarimwe binyuze mumutwe wapfuye kugirango bakore firime ifite gahunda itunganijwe neza, itangwa hagati yabantu, guhuza cyane hamwe nubunini bwimikoranire.Ukurikije uburyo butandukanye bwo gukora, irashobora kugabanwa muri firime ya co-extrusion ya firime hamwe na firime ya co-extrusion.Ibikoresho bya PVDC mubisanzwe bikoreshwa nkurwego rwagati rwinzitizi ya firime ikomatanya.Ibiranga imikorere: inzitizi ndende, isuku nziza, resin yumuti ikoreshwa muguhuza, wirinda ikibazo cyibisigisigi byumusemburo wumye (bishingiye kuri solvent), kandi birashobora gutekwa munsi ya dogere 100;Firime irashobora gutunganywa nubushyuhe bwa kabiri ikoresheje umusaruro wamashami yatemba;Hariho ibice byinshi bishobora gukorwa, none bigeze kuri 13.Umubyimba wa interlayer urashobora gukorwa cyane, ushobora kuzigama ingano ya resin hamwe nigiciro kinini kandi ukabona imikorere yubukungu.
