Imikorere no gukoresha firime yo gupakurura plastiki - Gufata Eva na Pva nkingero

Ethylene-Vinyl Acetate Film ya Copolymer
Evalim, zigaragara kuri elastity nziza cyane, zikunze guterwa no gukandagira kubumba. Imitungo yiyi firime ifitanye isano rya bugufi nibikubiye muri vinyl acetate (VA). Mugihe ibirimo VI biriyongera, filime itezimbere mubijyanye na elastique, guhangayikishwa no kurwanya, kurwanya ubushyuhe buke, nubushyuhe bukabije. Iyo ibirimo VI bigera kuri 15% ~ 20%, imikorere yayo iragereranwa niya firime ya PVC yoroshye. Ibinyuranye, mugihe ibirimo VI biri munsi, imikorere ya firime yegereye izo film. Mubisanzwe, ibikubiye muri filime ya Eva bigenzurwa murwego rwa 10% ~ 20%.
Filime ya Eva izwiho gukorera mu mucyo, byoroshye, no kwiyigisha kumva neza. Guhangayikishwa cyane no gutandukana no kwishyira hejuru bituma habaho hejuru ya 59% ~ 80%, bikaba firime nziza ya Spiral. Mu rwego rwo gupakira, birakoreshwa cyane mukusanyirizwa no gupfunyika agasanduku hamwe nibicuruzwa byatewe na kamere, kimwe no gupfunyika pallets. Muri icyo gihe, Filime ya Eva irakwiriye kandi gukora umusaruro upakira ibikoresho biremereye nk'ifumbire n'ibikoresho fatizo. Byongeye kandi, ifite ubushyuhe buhebuje buke bukabije bwa kashe no gushyirwaho ikimenyetso, kandi akenshi bikoreshwa nkubushyuhe bwa kashe kuri firime zidasanzwe.
Polyvinyl firime
Uburyo bwo kubyara bwa Pva Film harimo igisubizo no gukandamira. Bitewe nubushyuhe bwo hejuru bwa PVA nibibera ubushyuhe bwa delepositike, binjira neza biragoye, bityo rero plasitike y'amazi ikunze gukoreshwa mukugabanya ubushyuhe bwo gutunganya. Muri ubu buryo, film igomba gukama no kubura umwuma nyuma yo kubumba kugirango ubone film ifatika ya Pva. Mu rwego rwo gupakira, inganda zihitamo gukoresha uburyo bwo gutanga ibikoresho bya Pva.
Filime za Pva zirashobora kugabanywamo firime zirwanya amazi hamwe na firime zo gufunga amazi. Filime zirwanya amazi zikozwe muri Pva impamyabumenyi irenze 1000 kandi yuzuye kandi ikozwe muri film zifata amazi ya SAPOSIDS ya SAPOSIDS ya SAPOSIDS ifite imbaraga zo hasi. Mubisabwa gupakira, dukoresha cyane cyane gukoresha firime ya Pva.
Filime ya Pva, ihagaze neza mu mucyo kandi ikunda kwigunga kw'amashanyarazi no kwinjiza amashanyarazi no kwinjiza umukungugu, ariko nanone ifite imikorere myiza yo gucapa. Mu bihugu byumye, bigaragaza ko andikiranuka no kugumana impumuro nziza, ndetse no kurwanya peteroli. Byongeye kandi, film za Pva zifite imbaraga nziza zubukanishi, gukomera, no kurwanya guhangayikishwa no gutontoma, kandi birashobora kudodo. Ariko, kubera ubushuhe bwarwo bushingiye ku buntu no kwinjiza amazi bikomeye, hagomba kubaho neza. Kugirango ukemure iki kibazo, polyvinylidene chlolode ya chlolode, ni ukuvuga ku mutima, ubusanzwe ikoreshwa mu kuzamura ubukana bwayo, kugumana impumuro nziza no kurwanya ubuhehere. Iyi film yafashwe idasanzwe ya Pva nibyiza kubipfunyika ibiryo.
Filime ya PVA ikoreshwa nkigice cya bariyeri ya firime zihuje, kandi ikoreshwa cyane mugupakira ibiryo byihuse, ibikomoka ku nyama, ibicuruzwa bya cream nibindi biribwa. Muri icyo gihe, film yayo imwe nayo ikoreshwa cyane mubipfunyika byimyenda n'imyambaro. Byongeye kandi, film ihujwe namazi kandi ifite imikorere myiza muri metering no gupakira imiti nkibitaro byacitsemo ibice, ibikoresho, imiti yica udukoko, nibindi.
Muri rusange,firime yo gupakira plastiqueni Inshingano mu rwego rwo gupakira, kandi imitungo yabo idasanzwe ibafasha kuzuza ibikenewe bitandukanye no gusaba gupakira.
