Uburyo PVC Stabilizers zahinduye isi ya filime zanditsweho kalendari

Wigeze wibaza uburyo umwenda wo kwiyuhagiriramo wa PVC ugaragara neza wihanganira imyaka myinshi y'umwuka n'izuba udacika cyangwa ngo ushire? Cyangwa uburyo agapapuro k'ibiribwa bibonerana - gapfunyikamo ibiryo bikomeza kugumisha ibiribwa byawe bishya mugihe bigumana isura nziza? Ibanga riri mu kintu cy'ingenzi ariko gikunze kwirengagizwa:Ibintu bishyigikira PVCMu rwego rwo gukora filime zikozwe mu buryo bwa kalendari, izi nyongeramusaruro ni abahanga badacecetse bahindura polyvinyl chloride isanzwe (PVC) mo ibikoresho bifite imikorere myiza. Reka dukureho ibice by'ingenzi hanyuma turebe uruhare rwabyo rw'ingenzi muri icyo gikorwa.

Iby'ibanze bya Filime za Calendered na PVC Intege nke

Filimi zikozwe mu gihe cy’ibizamini bikorwa binyuze mu guca imvange ya PVC ishyushye mu buryo butandukanye, ikayihinduramo urupapuro ruto kandi rusa neza. Ubu buryo bukoreshwa cyane mu gukora ibintu nk'ibikoresho byo gupfunyika, ibifuniko by'inganda, na filimi zo gushushanya bitewe n'ubushobozi bwayo n'ubushobozi bwo gukora ubunini buhamye. Ariko, PVC ifite agatsinsino ka Achilles: imiterere yayo ya molekile irimo atome za chlorine zidahindagurika zituma ishobora kwangirika cyane iyo ihuye n'ubushyuhe, urumuri na ogisijeni.

Mu gihe cyo gukora calender, PVC ikorerwa ubushyuhe bwinshi (kuva kuri 160°C kugeza 200°C) kugira ngo ishonge neza kandi ihinduke neza. Iyo idakingiwe, ibikoresho birangirika vuba, bisohora aside hydrochloric (HCl) bigatera ibara, kwangirika no gutakaza imiterere ya mekanike. Aha niho ibintu bitera PVC guhagarara nk'ibikemura ikibazo gikomeye.

Uruhare runini rw'ibikoresho bitera imbaraga bya PVC mu gukora filime za kera

1. Ubushyuhe: Kubungabunga ubuziranenge mu gihe cyo gutunganya

Inshingano y'ibanze ya PVC stabilizers mu gukaraba ni ukurinda ibikoresho kwangirika k'ubushyuhe. Guhura n'ubushyuhe bwinshi mu gihe cyo gukandagira rollers bishobora gutera uruhererekane muri PVC, bigatera ishyirwaho ry'imigozi ibiri ihuza ibintu igahindura ibintu umuhondo cyangwa umukara. Stabilizers zikora:

Kunyunyuza aside hidrokloriki:Bigira ingaruka iyo HCl irekuwe mu gihe PVC iboze, bikayirinda ko ikomeza kwangirika. Urugero, ibintu bitera imbaraga bishingiye ku byuma nkakalisiyumu - zinki or barium - zincIbikoresho bifata molekile za HCl, bigakuraho ingaruka mbi zazo.

Gusimbuza atome za Chlorine zidahamye:Ibice bikora bya stabilizers, nka iyoni z'icyuma, bisimbura atome za chlorine zidakomeye mu muyoboro wa PVC, bigatuma habaho imiterere ihamye ya molekile. Ibi byongerera cyane igihe ubushyuhe bw'ibikoresho mu gihe cyo gupima ubushyuhe bwinshi.

2.Umurinzi w'amabara: Gukomeza ubwiza bw'ubwiza

Mu mikoreshereze aho isura isobanutse neza ari ngombwa—nk'ibipfunyika mu biribwa cyangwa imyenda ibonerana—isura ihamye y'amabara ntabwo ivugwaho rumwe. Ibintu bifasha mu kubungabunga amabara bya PVC bigira uruhare runini mu gukumira ihinduka ry'amabara:

Umurimo wo kurwanya ogisijeni:Bimwe mu bintu bitera imbaraga, cyane cyane ibirimo ibintu bikomoka ku bimera cyangwa fosfite, bikora nk'ibirwanya okisidanti. Bikuraho ibintu bitera imbaraga zikomoka ku bushyuhe cyangwa urumuri, bikabuza kwibasira molekile za PVC bigatuma zihinduka umuhondo.

Ubudahangarwa bw'imiraba ya UV:Ku mafiriti yakoreshejwe hanze – akoreshwa mu gihe cya karendari, ibipimo bikingira imirasire y'izuba bikingira imirasire y'izuba. Ibi ni ingenzi ku bikoresho nk'ibipfundikizo by'ibikoresho byo mu busitani cyangwa amafiriti y'ubusitani, bikarinda ibara ryabyo n'imbaraga zabyo uko igihe kigenda gihita.

3.Inyongeramusaruro: Yongera imiterere ya mekanike

Filimi zikozwe muri kalendari zigomba kuba zoroshye, ziramba, kandi zidashobora kwangirika. Ibintu bifasha mu kubungabunga PVC bigira uruhare muri ibi bintu:

Gusiga amavuta ku gipimo cya Melt:Hari ibintu bimwe na bimwe bitera imbaraga, nk'ubwoko bw'icyuma – isabune, nabyo bikora nk'amavuta yo kwisiga imbere. Bigabanya kwangirika mu gice cya PVC mu gihe cyo gukaraba, bigatuma kigenda neza hagati y'ibizingo. Ibi bituma habaho firime imwe kandi ifite ubuso bwiza kandi hakabaho inenge nke.

Kongera Iterambere ry'Igihe Kirekire:Mu gukumira kwangirika, ibintu bikomeza imikorere ya filime mu gihe cyose imaze ikora. Urugero, umukandara wo mu nganda ukoresha PVC urimo ibintu bikomeza imikorere yawo neza kandi bigakomeza gukomera nubwo wamaze imyaka myinshi ukoreshwa cyane.

4.Umufatanyabikorwa w’ibidukikije: Kuzuza amahame ngenderwaho y’umutekano

Bitewe n’ibibazo by’ibidukikije n’ubuzima bikomeje kwiyongera, ibikoresho bigezweho byo kubungabunga ibidukikije bya PVC byagenewe kubungabunga ibidukikije. Ku mafirime ya kera akoreshwa mu gupfunyika ibiryo cyangwa mu buvuzi, ibikoresho bibungabunga ibidukikije bigomba:

Ntukagire uburozi:Ibikoresho bidakoresha ibyuma biremereye nka calcium na zinc byasimbuye amahitamo gakondo ashingiye kuri lisansi. Ibi ni byiza kubikora mu buryo butaziguye ku biribwa kandi bikurikiza amabwiriza akomeye agenga ibiribwa (urugero, FDA muri Amerika cyangwa amabwiriza agenga umutekano w'ibiribwa mu muryango w'ubumwe bw'ibihugu by'Uburayi).

Kugabanya ingaruka ku bidukikije:Bamwe mu bakora ibikoresho barimo gushakisha uburyo bwo kubungabunga ibintu bishobora kubora cyangwa kongera gukoreshwa, bareba ko filimi zanditseho kalendari zishobora gutabwa cyangwa kongera gukoreshwa nta kwangiza isi.

Inyigo ku ikoreshwa rya filime za kera

Gupfunyika ibiryo:Isosiyete ikomeye ikora ibiribwa yahinduye ibyuma bya PVC bya calcium - zinc - kugira ngo bikoreshwe mu gupakira ibyo kurya. Ibi bikoresho ntibihuye gusa n'ibisabwa mu mutekano w'ibiribwa ahubwo byananogeje ubushyuhe bwa firime - gufunga no kudafata amavuta n'ubushuhe, bikongera igihe cyo kubikwa kw'ibicuruzwa.

Ubwubatsi:Mu nganda z'ubwubatsi, firime za PVC zahinduwe zifite inyongeramusaruro za UV zikoreshwa nk'urukiramende rudapfa amazi. Izi firime zishobora kwihanganira ikirere kibi mu gihe cy'imyaka ibarirwa muri za mirongo, bitewe n'ubushobozi bwo kurinda bw'izi firime, bigatuma hagabanuka gukenera kuzisimbuza kenshi.

Ejo hazaza ha PVC Stabilizers muri Filime za Calendered

Uko ikoranabuhanga ritera imbere, ni ko icyifuzo cy'ibikoresho bikomeza gukora PVC mu buryo bunoze kandi burambye gikomeza kwiyongera. Abashakashatsi barimo gukora:

Ibikoresho Bidahindura Imiterere:Ibi bihuza ubushyuhe, UV, n'uburinzi bwa antioxydants mu buryo bumwe, byoroshya inzira yo gukora no kugabanya ikiguzi.

Ibikoresho Bishinzwe Gutuza Ibidukikije (Bio - Stabilizers):Izi nzira zishingiye ku bidukikije, zikomoka ku mitungo ishobora kongera gukoreshwa, zigamije kugabanya ingaruka mbi ku bidukikije za filime zanditswe mu gihe cyashize, ariko ntizigabanye imikorere yazo.

Mu gusoza, ibikoresho bitanga umutekano bya PVC si inyongeramusaruro gusa—ni byo shingiro ry’ikorwa rya filime za kera. Kuva ku kurinda ibikoresho mu gihe cyo gutunganya ubushyuhe bwinshi kugeza ku kurinda umutekano no kuramba mu bicuruzwa bikoreshwa, ingaruka zabyo ntizishidikanywaho. Mu gihe inganda ziharanira guhanga udushya no kuramba, izi ntwari zitaramenyekana zizagira uruhare runini mu gushyiraho ahazaza ha filime za kera.

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 ibikoresho. Niba ushaka kumenya byinshi ku bikoresho bitanga ubushobozi bwo gupima no gupima, urakaza neza kutwandikira igihe icyo ari cyo cyose!
