Iziqinisi ze-Liquid Barium Zinc PVCizithasiselo ezikhethekile ezisetshenziswa ekucutshungulweni kwe-polyvinyl chloride (PVC) ukuthuthukisa ukuzinza kokushisa nokukhanya, ukuvimbela ukuwohloka ngesikhathi sokukhiqiza nokwandisa isikhathi sokuphila kwezinto. Nansi incazelo eningiliziwe yokwakheka kwazo, izinhlelo zokusebenza, izinto ezicatshangelwayo zomthetho, kanye nemikhuba yemakethe:
Ukwakheka kanye Nendlela Yokusebenza
Lezi ziqinisi zivame ukuba nosawoti we-barium (isb., i-alkylphenol barium noma i-2-ethylhexanoate barium) kanye nosawoti we-zinc (isb., i-2-ethylhexanoate zinc), kuhlanganiswe nezingxenye ezisebenzisanayo njenge-phosphites (isb., i-tris(nonylphenyl) phosphite) ye-chelation kanye ne-solvents (isb., uwoyela wamaminerali) wokuhlakazeka. I-barium inikeza ukuvikelwa kokushisa kwesikhashana, kanti i-zinc inikeza ukuzinza kwesikhathi eside. Ifomu loketshezi liqinisekisa ukuxubana okufanayo ekwakhiweni kwe-PVC. Izakhi zakamuva nazo zifaka ama-polyether silicone phosphate esters ukuthuthukisa ukuthambisa kanye nokubonakala, kunciphisa ukumuncwa kwamanzi ngesikhathi sokupholisa.
Izinzuzo Eziyinhloko
Akunabo ubuthi: Njengoba zingenazo izinsimbi ezisindayo njenge-cadmium, zihambisana nezindinganiso zokuxhumana kokudla kanye nezinga lezokwelapha (isb., amamaki avunyelwe yi-FDA kwezinye izinhlobo).
Ukusebenza Kahle Kokucubungula: Isimo soketshezi siqinisekisa ukusabalala kalula kuma-compounds athambile e-PVC (isb., amafilimu, izintambo), kunciphisa isikhathi sokucubungula kanye nokusetshenziswa kwamandla.
Ukusebenza Kahle Kwezindleko: Ukuncintisana nama-organic tin stabilizers ngenkathi kugwenywa izinkinga zobuthi.
Imiphumela YokubambisanaUma zihlanganiswa neziqinisi ze-calcium-zinc, zibhekana nezinkinga "zokulungisa" ekukhishweni kwe-PVC okuqinile ngokulinganisela ukuthambisa kanye nokuqina kokushisa.
Izicelo
Imikhiqizo ye-PVC ethambile: Isetshenziswa kabanzi kumafilimu aguquguqukayo, izintambo, isikhumba sokwenziwa, kanye namadivayisi ezokwelapha ngenxa yokungabi nobuthi nokugcinwa kwawo okucacile.
I-PVC eqinile: Kuhlanganiswe neiziqinisi ze-calcium-zinc, zithuthukisa ukucutshungulwa kwamafilimu namaphrofayili, zinciphisa "ukushelela kwezinto ngesikhathi sokukhipha).
Izicelo Ezikhethekile: Amafomula abonakala kakhulu okupakisha kanye nemikhiqizo engamelani ne-UV uma ehlanganiswa nama-antioxidants afana ne-2,6-di-tert-butyl-p-cresol.
Izinto Ezicatshangelwayo Zokulawula Nezemvelo
Ukuthobela i-REACH: Ama-compound e-Barium alawulwa ngaphansi kwe-REACH, ngemikhawulo ku-barium encibilikayo (isb., ≤1000 ppm emikhiqizweni yabathengi). Iningi lama-liquid barium zinc stabilizers lihlangabezana nale mingcele ngenxa yokuncibilika okuphansi.
Ezinye izindlela: Izithambisi ze-calcium-zinc ziya ngokuya zithandwa ngenxa yemithetho eqinile yezemvelo, ikakhulukazi eYurophu. Kodwa-ke, izithambisi ze-barium zinc zisathandwa kakhulu ekusetshenzisweni kokushisa okuphezulu (isb., izingxenye zezimoto) lapho i-calcium-zinc yodwa ingase inganeli.
Ukusebenza kanye Nedatha Yobuchwepheshe
Ukuzinza Kokushisa: Ukuhlolwa kokushisa okuqinile kubonisa ukuzinza okude (isb., imizuzu engu-61.2 ku-180°C yamafomula ane-hydrotalcite co-stabilizers). Ukucubungula okunamandla (isb., i-twin-screw extrusion) kuzuza ngezakhiwo zazo zokugcoba, kunciphisa ukuwohloka kwe-shear.
Ukucaca: Amafomula athuthukisiwe anama-ester e-silicone e-polyether afinyelela ukucaca okuphezulu kokukhanya (ukudluliselwa okungu-≥90%), okwenza afaneleke kumafilimu okupakisha.
Ukumelana Nokufuduka: Iziqinisi eziklanywe kahle zibonisa ukufuduka okuphansi, okubaluleke kakhulu ekusetshenzisweni okufana nokupakisha ukudla lapho ukufuduka okungeziwe kuyinkinga.
Amathiphu Okucubungula
Ukuhambisana: Gwema ukusebenzisa ngokweqile izithambisi ze-stearic acid, njengoba zingase zisabele nosawoti we-zinc, okusheshisa ukuwohloka kwe-PVC. Khethaizinzisi ezihlangenenjengamafutha kasoya afakwe i-epoxidized ukuze kuthuthukiswe ukuhambisana.
IsilinganisoUkusetshenziswa okuvamile kusuka ku-1.5–3 phr (izingxenye nge-resin eyikhulu) ku-PVC ethambile kanye no-0.5–2 phr ekwakhiweni okuqinile uma kuhlanganiswa neziqinisi ze-calcium-zinc.
Izitayela Zemakethe
Abashayeli Bokukhula: Isidingo seziqinisi ezingezona ezinobuthi e-Asia-Pacific naseNyakatho Melika sithuthukisa ukusungulwa kwezakhi ze-barium zinc. Isibonelo, imboni ye-PVC yaseShayina iya ngokuya isebenzisa iziqinisi ze-barium zinc eziwuketshezi zokukhiqizwa kwentambo/ikhebula.
Izinselele: Ukwanda kweziqinisi ze-calcium-zinc (okulinganiselwa ukuthi yi-CAGR engu-5–7% ezintweni zezicathulo kanye nemikhakha yokupakisha) kuveza ukuncintisana, kodwa i-barium zinc igcina indawo yayo ekusetshenzisweni okuphezulu.
Ama-Liquid Barium Zinc PVC Stabilizers anikeza ibhalansi yokusebenza kahle kwezindleko, ukuzinza kokushisa, kanye nokuhambisana nemithetho, okwenza kube yinto ebalulekile emikhiqizweni ye-PVC ethambile neqinile kancane. Ngenkathi izingcindezi zemvelo ziqhubela phambili ekushintsheni kwezinye izindlela ze-calcium-zinc, izakhiwo zazo ezihlukile ziqinisekisa ukufaneleka okuqhubekayo ezimakethe ezikhethekile. Abenzi be-formula kumele balinganise ngokucophelela izidingo zokusebenza neziqondiso zomthetho ukuze bandise izinzuzo zabo.
