PVC stabilisateurni ishingiro ryimikorere no kuramba kwimpumyi za Venetiya - birinda kwangirika kwubushyuhe mugihe cyo kuyikuramo, kurwanya kwambara ibidukikije, no kwemeza kubahiriza amahame yumutekano ku isi. Guhitamo stabilisateur nziza bisaba guhuza ibicuruzwa bisabwa (urugero, gukoresha imbere murugo no gukoresha hanze, estetique) hamwe na chimie stabilisateur, mugihe uhuza kubahiriza amategeko, ikiguzi, nuburyo bwo gutunganya neza. Hasi nubuyobozi, tekinike yo kuyobora guhitamo neza.
Tangira ukurikiza amabwiriza: Ibipimo byumutekano bitaganirwaho
Mbere yo gusuzuma imikorere, shyira imbere stabilisateurs zujuje amabwiriza yo mukarere no gushyira mu bikorwa-kutubahiriza ingaruka yibicuruzwa byibutswe hamwe nimbogamizi zo kubona isoko.
• Ibibujijwe ku isi ku byuma biremereye:Isasu, kadmium, hamwe na mercure ishingiye kuri stabilisateur birabujijwe ahanini kubicuruzwa byabaguzi nkimpumyi za Venetiya. Amabwiriza y’ubumwe bw’ibihugu by’Uburayi (Umugereka wa XVII) abuza kuyobora ibicuruzwa bya PVC hejuru ya 0.1%, mu gihe CPSC yo muri Amerika igabanya isasu na kadmium mu bibanza by’abana (urugero, impumyi z’incuke). Ndetse no ku masoko azamuka, Ubushinwa GB 28481 hamwe n’ubuziranenge bwa BIS mu Buhinde buteganya gukuraho ibyuma biremereye.
• Ibyiza byo mu kirere (IAQ) Ibisabwa:Kubatabona cyangwa ubucuruzi bwimpumyi, irinde stabilisateur zirimo phthalate cyangwa ibinyabuzima bihindagurika (VOC). Porogaramu yo muri Amerika EPA yo mu nzu ya AirPLUS hamwe na EcoLabel y’ubumwe bw’ibihugu by’Uburayi ishyigikira inyongeramusaruro nke za VOC, gukoracalcium-zinc (Ca-Zn)cyangwa amabati kama ubundi buryo bwiza kuruta Barium-Cadmium-Zinc (Ba-Cd-Zn).
• Ibiryo-Guhuza cyangwa Kuba hafi yubuvuzi:Niba impumyi zikoreshwa mu gikoni cyangwa mu bigo nderabuzima, hitamo stabilisateur zujuje FDA 21 CFR §175.300 (US) cyangwa EU 10/2011 (ibikoresho bya pulasitike bihura n’ibiribwa), nka methyl tin mercaptide cyangwa inganda zifite isuku nyinshi Ca-Zn.
Suzuma uburyo bwo gutunganya ibintu
Imikorere ya stabilisateur iterwa nuburyo ihuza neza na PVC yawe hamwe nibikorwa byo gukora.
• Umurongo wa Extrusion Guhuza:Kugirango uhore usohora ibice byimpumyi, irinde stabilisateur zitera gupfa (urugero, Ca-Zn yo mu rwego rwo hasi hamwe na aside irike cyane). Hitamo mbere yoguhuza stabilisateur (aho kuvanga ifu) kugirango wemeze gutatanya kimwe, kugabanya itandukaniro ryubunini bwa slat.
• Amavuta yo kwisiga:Stabilisateur ikorana namavuta (urugero, ibishashara bya polyethylene) kugirango bitezimbere.Ca-Zn stabilisateurbisaba amavuta yimbere yimbere kugirango wirinde "isahani" (ibisigara hejuru yubutaka), mugihe amabati ahuza neza hamwe namavuta yo hanze kugirango arekure neza.
• Batch vs Gukomeza umusaruro:Kubuto-buto, impumyi yamabara yihariye, stabilisateur yamazi (urugero, amazi Ca-Zn) itanga dosiye yoroshye. Kugirango habeho umusaruro mwinshi, stabilisateur stabilisateur yerekana neza.
Kuringaniza Igiciro, Kuramba, no gutanga Urunigi ruhamye
Nubwo imikorere ari ingenzi, ibintu bifatika nkigiciro ningaruka ku bidukikije ntibishobora kwirengagizwa.
• Ikiguzi-cyiza:Ca-Zn stabilisateur itanga impirimbanyi nziza yimikorere nigiciro cyimpumyi nyinshi zo murugo (20-30% bihendutse kuruta amabati kama). Ba-Zn nubukungu bwo gukoresha hanze ariko wirinde kubisabwa murugo kubera ingaruka zuburozi.
• Kuramba & Gusubiramo:Hitamo stabilisateur zunganira sisitemu ya PVC. Ca-Zn irahujwe rwose no gutunganya imashini (bitandukanye na sisitemu cyangwa kadmium, yanduza PVC ikoreshwa neza). Bio ishingiye kuri Ca-Zn (ikomoka ku biryo bishobora kuvugururwa) ihuza na gahunda y’ubukungu bw’ibihugu by’Uburayi hamwe n’ibikenerwa n’abaguzi ku bicuruzwa bitangiza ibidukikije.
• Gutanga Urunigi Kwizerwa:Ibiciro bya Zinc na tin birahindagurika - hitamo ibintu byinshi biva muri stabilisateur (urugero, kuvanga Ca-Zn) aho guhitamo niche (urugero, amabati ya butyl) kugirango wirinde gutinda kw umusaruro.
Kwipimisha & Kwemeza: Igenzura ryanyuma mbere yumusaruro wuzuye
Mbere yo kwiyemeza gutuza, kora ibi bizamini kugirango umenye imikorere:
?
• Ikizamini gishyushye:Kuramo ibyitegererezo by'icyitegererezo hanyuma ubishyire kuri 200 ° C muminota 30 - reba ibara cyangwa iyangirika.
• Ikizamini cy'ikirere:Koresha itara rya xenon kugirango wigane amasaha 1.000 ya UV yerekanwe - bapima kugumana amabara (ukoresheje spekitifotometero) hamwe nuburinganire bwimiterere.
• Ikizamini cya IAQ:Gisesengura imyuka ya VOC kuri ASTM D5116 (US) cyangwa ISO 16000 (EU) kugirango urebe niba hubahirizwa ibipimo byimbere mu nzu.
Ikizamini cya mashini: Ibice byerekana kugoreka no kugerageza ingaruka (kuri ISO 178) kugirango hemezwe imikorere irwanya intambara.
Urwego rwo gufata ibyemezo kuri PVC Venetian Impumyi Zitajegajega
• Shyira imbere kubahiriza:Banza ukureho ibyuma biremereye cyangwa-VOC stabilisateur ubanza.
• Sobanura ikibazo cyo gukoresha:Mu nzu (Ca-Zn kuri IAQ) na Hanze (Ca-Zn + HALS cyangwaBa-Znikirere).
• Guhuza ibikenewe gutunganya:Mbere-yongewe kubijwi byinshi, isukari kubice byabigenewe.
• Kwemeza imikorere:Gerageza ubushyuhe butajegajega, ikirere, hamwe nubukanishi.
• Hindura ibiciro / Kuramba:Ca-Zn nibisanzwe kubisabwa byinshi; amabati kama gusa kubwiza-bwiza, impumyi nkeya.
Ukurikije ubu buryo, uzahitamo stabilisateur yongerera igihe kirekire impumyi, yujuje amabwiriza yisoko, kandi igahuza nintego zirambye-zikomeye muguhatanira isoko ryimpumyi PVC kwisi yose.
