IziQinisekisi ze-Liquid Barium Zinc PVCzizongezo ezikhethekileyo ezisetyenziswa ekucutshungulweni kwe-polyvinyl chloride (PVC) ukuphucula uzinzo lobushushu nokukhanya, ukuthintela ukuwohloka ngexesha lokwenziwa kunye nokwandisa ubomi bezinto. Nantsi inkcazelo eneenkcukacha malunga nokwakheka kwazo, usetyenziso, iingqwalasela zomthetho, kunye neendlela zemarike:
Ukwakhiwa kunye neNkqubo
Ezi ziqinisi zihlala ziquka iityuwa ze-barium (umz., i-alkylphenol barium okanye i-2-ethylhexanoate barium) kunye neetyuwa ze-zinc (umz., i-2-ethylhexanoate zinc), zidityaniswe nezinto ezisebenzisanayo ezifana neephosphites (umz., i-tris(nonylphenyl) phosphite) ze-chelation kunye nezinyibilikisi (umz., iioyile zeminerali) zokusasazwa. I-barium ibonelela ngokhuseleko lobushushu lwexesha elifutshane, ngelixa i-zinc inika uzinzo lwexesha elide. Uhlobo lolwelo luqinisekisa ukuxubana okufanayo kwiifomyula ze-PVC. Iifomyula zamva nje zikwabandakanya ii-esters ze-polyether silicone phosphate ukuphucula ukuthambisa kunye nokucaca, ukunciphisa ukufunxwa kwamanzi ngexesha lokupholisa.
Iingenelo eziphambili
Ayinatyhefu: Azinazo iimetali ezinzima ezifana ne-cadmium, ziyahambelana nemigangatho yokunxibelelana kokutya kunye nemigangatho yezonyango (umz., amanqanaba avunyiweyo yi-FDA kwezinye iindlela).
Ukusebenza kakuhle kokucubungula: Imeko yolwelo iqinisekisa ukusasazeka lula kwiikhompawundi zePVC ezithambileyo (umz., iifilimu, iingcingo), kunciphisa ixesha lokucubungula kunye nokusetyenziswa kwamandla.
Ukusebenza kakuhle kweendleko: Ikhuphisana neziqinisi zetin yendalo ngelixa kuthintelwa iingxaki zetyhefu.
Iziphumo zokusebenzisana: Xa zidityaniswe neziqinisi ze-calcium-zinc, zijongana nemiba "yokuxovula" kwi-PVC extrusion eqinileyo ngokulinganisela ukuthambisa kunye nokuzinza kobushushu.
Izicelo
Iimveliso zePVC ezithambileyo: Isetyenziswa kakhulu kwiifilimu eziguquguqukayo, iintambo, ulusu olungeyolwenziweyo, kunye nezixhobo zonyango ngenxa yokuba azinatyhefu kwaye azinazo iziphako.
I-PVC eqinileyo: Ngokudibeneyo neiziqinisi ze-calcium-zinc, ziphucula ukuqhubekeka kokusebenza kwiifilimu nakwiiprofayili, zinciphisa "ukutyibilika kwezinto ngexesha lokukhupha).
Izicelo ezikhethekileyo: Iifomyula ezibonakala ngokucacileyo kakhulu zokupakisha kunye neemveliso ezimelana ne-UV xa zidityaniswe nee-antioxidants ezifana ne-2,6-di-tert-butyl-p-cresol.
Izinto eziqwalaselwayo ngokweMithetho kunye neNdalo
Ukuthobela i-REACH: Iikhompawundi zeBarium zilawulwa phantsi kwe-REACH, kunye nemiqathango kwi-barium enyibilikayo (umz., ≤1000 ppm kwiimveliso zabathengi). Uninzi lwezinzisi ze-barium zinc ezingamanzi ziyahlangabezana nale mida ngenxa yokunyibilika okuphantsi.
Ezinye iindlela: Iziqinisi zeCalcium-zinc ziyanda ngenxa yemithetho engqongqo yokusingqongileyo, ingakumbi eYurophu. Nangona kunjalo, iziqinisi zeBarium Zinc zihlala zikhethwa kwiindawo ezishushu kakhulu (umz., iindawo zeemoto) apho iCalcium-zinc yodwa isenokunganeli.
Idatha yokusebenza kunye noBugcisa
Uzinzo lobushushu: Uvavanyo lobushushu obungashukumiyo lubonisa uzinzo olude (umz., imizuzu engama-61.2 kwi-180°C kwiifomyula ezine-hydrotalcite co-stabilizers). Ukucubungula ngokunamandla (umz., i-twin-screw extrusion) kuzuza kwiipropati zazo zokuthambisa, okunciphisa ukubola kwe-shear.
Ukungafihlisi: Iifomyula eziphambili ezinee-ester ze-silicone ze-polyether zifumana ukucaca okuphezulu kokukhanya (≥90% yokudlulisa), nto leyo ezenza zifaneleke kwiifilimu zokupakisha.
Ukumelana nokuFuduka: Iziqinisi ezenziwe kakuhle zibonisa ukufuduka okuphantsi, okubaluleke kakhulu kwizicelo ezinje ngokupakishwa kokutya apho ukufuduka kwezongezo kuyingxaki.
Iingcebiso Zokucubungula
Ukuhambelana: Kuphephe ukusebenzisa kakhulu izithambisi ze-stearic acid, njengoko zinokusabela kwiityuwa ze-zinc, nto leyo ekhawulezisa ukuwohloka kwe-PVC. Khetha ukusebenzisaizinto ezizinzisa kunyenjengeoyile yesoya efakwe i-epoxidized ukuphucula ukuhambelana kwayo.
Idosi: Ukusetyenziswa okuqhelekileyo kususela kwi-1.5–3 phr (iinxalenye ngekhulu le-resin) kwi-PVC ethambileyo kunye ne-0.5–2 phr kwiifomyula eziqinileyo xa zidityaniswe neziqinisi ze-calcium-zinc.
Iindlela zeMarike
Abaqhubi Bokukhula: Imfuno yezinto ezizinzisa izinto ezingenatyhefu eAsia-Pacific naseMntla Melika ikhuthaza uphuhliso kwi-barium zinc formulations. Umzekelo, ishishini le-PVC laseTshayina lisebenzisa ngakumbi izinto ezizinzisa izinto ezizinzisa izinto ezizinzisa izinto ezizinzisa izinto ezisetyenziswa kwiintambo/iintambo.
Imingeni: Ukunyuka kwezithambisi ze-calcium-zinc (i-CAGR eqikelelweyo ye-5–7% kwizixhobo zezihlangu kunye namacandelo okupakisha) kuvelisa ukhuphiswano, kodwa i-barium zinc igcina indawo yayo kwizicelo zokusebenza okuphezulu.
Ii-Liquid Barium Zinc PVC Stabilizers zibonelela ngokulinganisela kokusetyenziswa kakuhle kweendleko, uzinzo kubushushu, kunye nokuthobela imithetho, nto leyo eyenza ukuba zibe yimfuneko kwiimveliso ze-PVC ezithambileyo neziqinileyo. Ngelixa uxinzelelo lokusingqongileyo luqhubela phambili ekutshintsheleni kwezinye iindlela ze-calcium-zinc, iimpawu zazo ezikhethekileyo ziqinisekisa ukufaneleka okuqhubekayo kwiimarike ezikhethekileyo. Abenzi beefomyula kufuneka balinganise ngononophelo iimfuno zokusebenza kunye nezikhokelo zomthetho ukuze bandise iingenelo zabo.
