Polyvinyl chloride (PVC), thermoplastic ikunzwe cyane, ifite intege nke zitari ibanga: ikunze kwangirika mu gihe cyo kuyitunganya no kuyikoresha. Ariko ntugire ubwoba! InjiraIbintu bishyigikira PVC, intwari zitavugwa cyane mu isi ya pulasitiki. Izi nyongeramusaruro ni ingenzi mu kugabanya imiterere y’ubushyuhe bwa PVC, bigakuraho kwangirika no kongera igihe cyo kubaho kwayo. Muri iyi nyandiko ya blog, turimo kwinjira mu isi ishimishije y’ibikoresho bitera imbaraga bya PVC, dusuzuma amoko yabyo, uburyo bikora, aho bikoreshwa, n’ibyerekezo bishimishije bigira uruhare mu hazaza habo.
PVC si ikindi gikoresho cya pulasitiki gusa; ni isoko y'amashanyarazi ikoreshwa mu buryo butandukanye. Kubera imiterere yayo myiza ya mekanike, ubushobozi bwayo bwo kurwanya imiti ihumanya ikirere, ubushyuhe bw'amashanyarazi buhanitse, n'igiciro cyayo kihendutse, PVC yageze mu nganda zitabarika, kuva ku bwubatsi no gupakira kugeza ku nsinga n'insinga ndetse n'ibikoresho by'ubuvuzi. Ariko, hari ikibazo. Imiterere ya molekile ya PVC irimo atome za chlorine zidahindagurika, iyo zihuye n'ubushyuhe, urumuri, cyangwa ogisijeni, zitera uruhererekane rw'ibintu ruzwi nka dehydrochlorination. Iyi reaction ituma ibikoresho bihinduka ibara, bigatakaza imikorere yabyo, amaherezo bikaba ntacyo bimaze. Niyo mpamvu kongeramo ibintu bihamye mu gihe cyo gutunganya no gukoresha PVC atari amahitamo gusa - ni ngombwa.
Ibintu bikomeza ubuziranenge bya PVC bishobora gushyirwa mu byiciro bitandukanye hashingiwe ku miterere yabyo ya shimiubwoko:
Ibikoresho Bidahindura Umunyu:Aba ni bo ba mbere mu mukino wo gupima ubushyuhe bwa PVC, bafite ubushobozi bwo kudatakaza ubushyuhe no kugabanya ikiguzi. Ariko, bitewe n’ibibazo by’uburozi bwabo, bagiye bagabanuka buhoro buhoro mu myaka ya vuba aha.
Ibikoresho Bidahindura Isabune mu Byuma:Iri tsinda ririmo izizwi cyane nka calcium-zinc na barium-zinc stabilizers. Zitanga ubushobozi bwo kudashyuha no kwisiga neza, bigatuma ziba zimwe mu zikoreshwa cyane muri iki gihe mu gupima PVC.
Ibikoresho Bidatera Ihindagurika rya Organotin:Bizwi cyane kubera ubushyuhe bwabyo burambye kandi butanga umusaruro uhagije, ibipimo by'ingufu bya organotin bifite igiciro kiri hejuru. Bikoreshwa cyane cyane mu bikoresho bya PVC bitanga umusaruro udasanzwe.
Ibikoresho Bidakora ku Isi Bidasanzwe:Nk’abana bashya muri aka gace, ibi bitera imbaraga mu kubungabunga ibidukikije bitanga ubushobozi bwo kurinda ubushyuhe, ntibigira uburozi, kandi bitanga ubwisanzure bwiza. Ariko, kimwe n’ibitera imbaraga mu kubungabunga organotin, biza ku giciro kiri hejuru ugereranyije.
Ibikoresho Bifasha mu Gutuza Ibidukikije mu Buryo bw'Ingirabuzimafatizo:Ubwabyo, ibi ntabwo bigira ubushobozi bwo gutuza. Ariko iyo bihujwe n'ibindi bintu bituza, bikora neza, bikongera imikorere myiza yo gutuza. Ingero zirimo fosfite na epoxide.
None se, ni gute neza neza ibi bintu bitera imbaraga bikora neza? Dore uburyo bw'ingenzi:
Uburyo bwo kwinjiza HCl:Ibikoresho bikomeza gukorana na hydrogène chloride (HCl) ikorwa mu gihe PVC yangiritse, bigahagarika ingaruka zayo zo kwikora.
Gusimbuza atome ya Chlorine idahindagurika:Iyoni z'icyuma ziri mu bintu bizigama zisimbura atome za chlorine zidahindagurika muri molekile ya PVC, bigatuma ubushyuhe bukomeza kwiyongera.
Umurimo wo kurwanya ogisijeni:Hari ibintu bitera imbaraga bifite ubushobozi bwo kurwanya ogisijeni, bifasha mu gukumira kwangirika kwa ogisijeni kwa PVC.
Ibintu bifasha mu kubungabunga PVC biri ahantu hose mu buzima bwacu bwa buri munsi, bigira uruhare runini mu bintu bitandukanye bya PVCibicuruzwa:
Ibikoresho bya PVC bikomeye:Tekereza ku miyoboro, imiterere, n'amashuka. Kuri ibi, ibikoresho bitera imbaraga mu gupima umunyu w'icyuma, ibikoresho bitera imbaraga mu isabune y'icyuma, n'ibikoresho bitera imbaraga mu gupima ubutaka bidakoresha amashanyarazi menshi ni byo bikunze gukoreshwa.
Ibikoresho bya PVC byoroshye:Ibintu nk'insinga, insinga, uruhu rw'ubukorano, na za firime bishingiye ahanini ku byuma bitera imbaraga isabune n'ibitera imbaraga umubiri.
Ibikoresho bya PVC bibonerana:Byaba ari amacupa cyangwa impapuro, ibintu bifasha mu gupima neza umubiri ni byo bikunze gukoreshwa kugira ngo habeho ubwumvikane busesuye.
Uko isi irushaho kwita ku bidukikije n'ikoranabuhanga rikomeza gutera imbere, ahazaza ha PVC stabilizers hari kugenda hagaragara ibintu bishimishije.inzira.
Kujya ku gasozi:Icyo twibandaho ni uguteza imbere ibintu bidashobora kwangiza ibidukikije, bitangiza ibidukikije, kandi bishobora kubora, nka calcium-zinc na rare earth stabilizers.
Kongera Ubushobozi:Hari imbaraga zo gushyiraho ibintu bitera imbaraga birushaho gukora neza ku giciro gito, bigabanya ikiguzi ariko bigakomeza gukora neza.
Imirimo yo Kugwiza:Tegereza kubona ibintu bitanga ubushyuhe buhamye kandi butuma ibintu bitagira ubushyuhe bihagarara cyangwa bikanatuma ibintu bitagira ubushyuhe buhagarara.
Imbaraga zo guhuza:Kuvanga ubwoko butandukanye bw'ibintu bitera imbaraga kugira ngo habeho ingaruka zihuriza hamwe kandi bigere ku musaruro mwiza wo gutuma ibintu bitera imbaraga, birimo kuba ikintu gikunze kugaragara.
Muri make, ibikoresho bikomeza PVC ni byo birinda PVC, bigamije ko ikora neza kandi ikamara igihe kirekire. Hamwe n'amabwiriza akaze y'ibidukikije n'iterambere ry'ikoranabuhanga rihoraho, ahazaza ni ah'ibikoresho bikomeza PVC bitangiza ibidukikije, bikora neza, bifite imikorere myinshi, kandi bivanze. Mukomeze gukurikirana ibi bishya—bigiye guhindura isi ya pulasitiki!
Topjoy ChemicalIsosiyete yahoraga yiyemeje gukora ubushakashatsi, iterambere, no gukora ibikoresho bya PVC bitanga ubushobozi bwo gupima no guteza imbere. Itsinda ry’abahanga mu bushakashatsi n’iterambere rya Topjoy Chemical Company rikomeje guhanga udushya, kunoza imiterere y’ibicuruzwa hakurikijwe ibyo isoko risaba n’iterambere ry’inganda, no gutanga ibisubizo byiza ku bigo bitanga umusaruro. Niba ushaka kumenya byinshi ku bijyanye na calcium-zinc PVC stabilizers, urakaza neza kutwandikira igihe icyo ari cyo cyose!
