Itandukaniro riri hagati ya calcium zinc stabilizer na composite lead salt stabilizer:

Ibikoresho bigabanya ubushyuhe bya kalisiyumu na calcium zinc stabilizer bivuga ibikoresho bigabanya ubushyuhe bya PVC, bigira uruhare mu kudahindagurika k'ubushyuhe mu ikorwa ry'ibicuruzwa bya PVC. Itandukaniro riri hagati y'ibyo byombi ni iri rikurikira:
Ibikoresho bipima ubushyuhe bya kalisiyumu zinc byujuje ibisabwa ku bidukikije kandi ubu bikoreshwa cyane. Ibiranga birimo ibi bikurikira:
1. Ikintu cy'ingenzi cyane kiranga ibintu bikomeza ubushyuhe bwa kalisiyumu ni uko bikoreshwa mu buryo buboneye n'ubudasobanutse mu bikoresho by'ubwubatsi bya chimique, kandi bikoreshwa cyane.
2. Igiciro kiri hasi ugereranyije n'icya organotin.
3. Ikorana neza kandi ihuza neza n'ibice bitera imbaraga mu byuma bya lead, tin, cadmium, na antimoni, kandi nta mwanda wa sulfur uhari. Ikwiriye abakora ibikoresho bya lead mu byuma bitera imbaraga mu byuma bisimbura ibintu bidafite uburozi kandi bitangiza ibidukikije.
4. Indi nyungu ikomeye y’ibikoresho bigabanya ubushyuhe bwa kalisiyumu ni uko birwanya ikirere neza, kandi ibicuruzwa byakozwe hakoreshejwe ibikoresho bigabanya ubushyuhe bya kalisiyumu bitazahinduka ibara.
Gukoresha imiti igabanya umunyu wa lisansi byagabanutse buhoro buhoro bitewe n'uburozi bwabyo. Imiterere yabyo ni iyi ikurikira:
1. Uburozi.
2. Ntibishobora gukoreshwa ku bicuruzwa bibonerana.
3. Gukingira neza amashanyarazi no kurwanya ikirere;
4. Igiciro gito;
5. Imikorere myiza yo gutunganya ibintu ikwiranye n'ibikorwa bitandukanye;
