Menene Metal Sabulu Stabilizers?
Metal sabulu stabilizerssu ne mahadi na organometallic da aka kafa ta hanyar amsa fatty acids (kamar stearic ko lauric acid) tare da oxides karfe ko hydroxides. Karafa na yau da kullun sun haɗa da alli, zinc, barium, cadmium (ko da yake ana ƙara fita don dalilai na muhalli), da magnesium. Sihirinsu ya ta'allaka ne wajen daidaita mahimman ayyuka guda biyu: tabbatar da PVC yayin sarrafa zafin jiki mai zafi (extrusion, gyare-gyaren allura) da kuma kare shi daga lalacewa na dogon lokaci a wuraren amfani na ƙarshe.
