Kwinkqubo ye-PVC, ukukhetha isizinzisi esifanelekileyo kudlula ngaphaya kobuchwephesha—kubumba ukusebenza kwemveliso, ukuthobela okusingqongileyo, kunye nokusebenza kakuhle kwexesha elide. Phakathi kwezinto ezahlukeneyo ezizinzisa kwimarike, izizinzisi ze-calcium zinc ziye zaba lukhetho oluthembekileyo kubavelisi abajonge ukulinganisela ukhuseleko, ukusebenza, kunye nokuzinza. Ngokungafaniyo nezizinzisi zesinyithi esinzima zemveli, ezi zixube zisebenzisa amandla entsebenziswano eekhompawundi ze-calcium kunye ne-zinc ukukhusela i-PVC ekuwohlokeni, zilungele uluhlu olubanzi lwezicelo zoshishino. Siza kuhlalutya into eyenza izizinzisi ze-calcium zinc zahluke, iimpawu zazo eziphambili, kunye nendlela ezibonelela ngayo ixabiso lokwenyani ekucutshungulweni kwe-PVC yemihla ngemihla.
IziQinisekisi zeCalcium Zinc Zikhutshwe Ngaphezulu Kokhuseleko Olusisiseko
Entliziyweni yabo,izinto eziqinisa i-calcium zinc—edla ngokubizwa ngokuba yi-Ca Zn stabilizer kwishishini—zizinto ezongeziweyo ezidityanisiweyo ezenzelwe ukunqanda ukuwohloka kwe-PVC ngexesha lokucubungula nokusetyenziswa kwayo. Ngenxa yokwakheka kwayo ngamakhemikhali, i-PVC iyawohloka ngokulula xa ivezwa kubushushu, ukukhanya, kunye noxinzelelo loomatshini. Olu qhekeko alonakalisi nje kuphela iimpawu zomzimba zesixhobo, njengokuqina kokuxinana kunye nokuguquguquka—lukwabangela ukutshintsha kombala, ukuqhekeka, kunye nokukhululwa kweemveliso eziyingozi. Izithambisi ze-calcium zinc zilwa noku ngokuphazamisa impendulo yetsheyini yokuwohloka, ukunciphisa iimveliso ezibangelwa yi-acidic, kunye nokukhusela iimolekyuli ze-PVC kumonakalo we-oxidative.
Yintoni eyahlulayoIsiqinisi se-Ca Znkwezinye iintlobo—ezifanailothe, i-cadmium, okanye ezinye iindlela ezisekwe kwi-tin—lulwakhiwo lwayo olungenabungozi, olunobuhlobo nokusingqongileyo. I-calcium kunye ne-zinc zizinto ezifumaneka ngokwendalo, ngoko ke ezi ziqinisi zihlangabezana nemigangatho yolawulo lwehlabathi efana nezikhokelo ze-REACH, RoHS, kunye ne-FDA. Oku kuthobela le mithetho yeyona nto ibalulekileyo, ngakumbi kwiimveliso ezisetyenziswa ekunxibelelaneni kokutya, kwizixhobo zonyango, okanye kwizinto zabantwana, apho ungcoliseko lwesinyithi esinzima luthintelwe ngokungqongqo. Ukongeza, iziqinisi ze-calcium zinc azinazo iikhompawundi ze-organic eziguquguqukayo (ii-VOC) kwaye azikhuphi msi unobungozi ngexesha lokucubungula, nto leyo edala indawo yokusebenza ekhuselekileyo kumaqela emveliso.
Iimpawu eziphambili zeCalcium Zinc Stabilizers
Iziqinisi zeCalcium zinc zenzelwe ukubonelela ngeempawu zokunyusa ukusebenza ezihlangabezana neemfuno zokulungiswa kwePVC yanamhlanje. Ezi mpawu zenzelwe ukujongana nemingeni eyahlukileyo yezicelo ezahlukeneyo, ukusuka kwimibhobho yePVC eqinileyo ukuya kumgangatho wevinyl oguquguqukayo. Nantsi inkcazo eneenkcukacha zeempawu zazo ezibalaseleyo:
• Uzinzo lobushushu bokucubungula amaqondo obushushu aphezulu
Ukumelana namaqondo obushushu aphezulu kwi-extrusion, i-injection molding, kunye ne-calendar ngumsebenzi ophambili wayo nayiphi na i-PVC stabilizer—kwaye i-calcium zinc stabilizers zibalaseleyo apha. Zibonelela ngokhuseleko oluthembekileyo lobushushu nokuba kubushushu bokucubungula obungaphezulu kwe-180°C. Icandelo le-calcium lisebenza njengomkhuseli wobushushu wexesha elide, ngelixa iikhompawundi ze-zinc zibonelela ngokhuseleko olukhawulezileyo nolwexesha elifutshane ekuwohlokeni kokuqala. Olu sebenziswano luqinisekisa ukuba i-PVC igcina ulungelelwaniso lwayo lwesakhiwo kunye nokuhambelana kombala kulo lonke umjikelo wokucubungula, inciphisa iinkunkuma kwaye iphucula ukusebenza kakuhle kwemveliso. Kwizicelo ezifana nemibhobho ye-PVC kunye neeprofayili, ezifuna ukunyamezela ubushushu obude ngexesha lokukhupha, olu zinzo lobushushu alunakuxoxiswana.
• Ukumelana ne-UV ukuze kusetyenziswe ngaphandle ixesha elide
Iimveliso zePVC zangaphandle—ezifana neesiding, ucingo, iipayipi zegadi, ukubala ezimbalwa—zijongene nemitha ye-UV engaguqukiyo, ekhawulezisa ukubola kwaye ibuna umbala ngokuhamba kwexesha. Izithambisi ze-calcium zinc ezisemgangathweni ophezulu zinokwenziwa ngee-UV absorbers kunye nee-antioxidants ukunyusa ukumelana ne-UV, zandise ubomi beemveliso zePVC zangaphandle. Oku kudla ngokuphelisa imfuneko ye-UV stabilizers ezongezelelweyo, kwenza kube lula ukwenziwa kweefomyula kwaye kunciphise iindleko. Ngokungafaniyo nezinye izithambisi zesinyithi esinzima eziqhekekayo phantsi kokukhanya kwe-UV, i-Ca Zn stabilizer igcina iipropati zayo zokukhusela, iqinisekisa ukuba iimveliso zePVC zangaphandle zigcina inkangeleko yazo kunye nokusebenza kwazo iminyaka.
