Kugereranya itandukaniro ry'ingenzi hagati ya PVC Calcium Zinc Stabilizers na Lead Salt Stabilizers:
1, Ubuziranenge n'uburozi ku bidukikije
1. Ituma kalisiyumu ikomeza gukora neza
Nta byuma biremereye nka lead na cadmium na gato, hakurikijwe amabwiriza y’ibidukikije ya EU RoHS/REACH;
Icyemezo cya FDA, gikwiriye urwego rw’umutekano nko gupakira ibiryo n’ibikoresho by’ubuvuzi.
2. Ituma umunyu ukomeza guhindagurika
Irimo icyuma gikomeye cy’ubutare, ivumbi ry’uburozi rituruka mu gihe cyo gutunganya, kandi kubishyira mu mwanya wabyo igihe kirekire bishobora kwangiza ubuzima bw’abantu;
Ibicuruzwa byasizwe bishobora guteza umwanda w’ubutaka n’amazi byoroshye.
2, Uburyo bwo guhagarara neza kw'ubushyuhe
1. Ituma kalisiyumu ikomeza gukora neza
Binyuze mu buryo bwo gusana bw’ibice bibiri: isabune ya zinc isimbuza atome za chlorine zidakora neza, isabune ya kalisiyumu ikongera isabune ya zinc kugira ngo yongere igihe cyo kudahinduka;
Ni ngombwa gukoresha imiti ihuza ibintu nka β – diketone na hydrotalcite kugira ngo wongere ubusugire (hamwe n'ingano ya 0.3% -2%).
2. Ituma umunyu ukomeza guhindagurika
Gukora urusobe rw'ibintu hakoreshejwe molekile za PVC, bigahagarika neza uburyo bwo gukuraho HCl;
Igice kimwe gishobora kugera ku bushyuhe burambye hatabayeho gukenera sisitemu zigoye zo guhuza.
3, Imikorere yo gutunganya
| Kugereranya ibintu | Iterambere rya zinc ya kalisiyumu | 铅盐稳定剂 |
| Ubushyuhe | Hakenewe kugenzura neza igipimo cy'amavuta yo gusiga (ingano irenze urugero ishobora kugwa) | Iza ifite imiterere y'amavuta yo kwisiga n'idirishya rinini ryo gutunganya |
| kugenzura ibara | Iyi mashini ikunda kugira ibara ry'ubururu kandi igomba gukosorwa no kongeramo toner | Ibara rituje cyane kandi rihindagurika gake hagati y'amabara |
| Uburyo bwo gushonga | Gabanya ubushyuhe bwo gushyira pulasitiki kuri 5-10 ℃ | Nta ngaruka nini igira ku bushyuhe bw'ingufu zishongeshejwe |
4, Imipaka y'ikoreshwa ry'ibipimo
1. Ituma kalisiyumu ikomeza gukora neza
Ibikoresho bibonerana bigomba kongeramo hypophosphite (0.5%) kugira ngo birusheho kunoza ubwisanzure;
Uburyo bwo kuzuza cyane (calcium carbonate> 30phr) bukunze guhura n'ibibazo by'ubukonje.
2. Ituma umunyu ukomeza guhindagurika
◉ Ikoreshwa gusa ku bicuruzwa bitagaragara neza (nk'imiyoboro n'imiterere);
Ahantu harangwamo sulfure mu majyaruguru hashobora gutuma ubuso bw'ibicuruzwa buhinduka sulfide kandi bugahinduka umukara.
5, Itandukaniro mu bukungu
Ubucucike bwa calcium zinc stabilizer buri hasi ho 40%, ibyo bikaba bishobora kongera ingano y'ibirungo byongewemo kandi bigagabanya ikiguzi;
Igiciro cy'ibikoresho bigabanya umunyu wa lead kiri hasi, ariko ikiguzi cy'inyongera cyo gutunganya ibyuma bikomeye kigomba kwishyurwa;
Binyuze mu kugereranya ibintu byinshi, bigaragara ko ibintu bitera imbaraga mu kubungabunga ibidukikije bifite akamaro kanini mu guhangana n’imihindagurikire y’ikirere, mu gihe ibintu bitera imbaraga mu kubungabunga umunyu wa lead bigifite agaciro kanini mu guhangana n’ibiciro no mu kugenzura ikiguzi.
