Ni izihe nyungu n'ibibi byo kongeramo hydrotalcite mu bintu bitera imbaraga calcium zinc?

Hydrotalc ni igikoresho cy'ingenzi mu gupima zinc ya kalisiyumu. Hydrotalc ifite imiterere n'imiterere byihariye, kandi imiterere yayo y'ibanze ni alkalinity na multi porosity, ifite imikorere idasanzwe kandi myiza. Ishobora kwinjiza neza hydrogen chloride isohoka mu gihe PVC yangiritse, igabanye umuvuduko wa hydrogen chloride ku ruhu rwa PVC, kandi igakora nk'ikintu kiyinjiza aside, kizwi kandi nka thermal stabilizer. Ikunze gukoreshwa nk'ikintu kiyinjiza ubushyuhe.
Hydrotalc ifite kandi ibyiza byo gukorera mu mucyo, gukingira ikirere, kurwanya imihindagurikire y'ikirere, no kwihutisha gutunganya. Ntabwo yandujwe na sulfide, ntabwo ari uburozi, kandi ishobora gukorana n'ibikoresho bigabanya ubushyuhe nka zinc sabune na organic tin. Ni ubwoko bw'ibikoresho bigabanya ubushyuhe bidahumanya ubushyuhe.
Imiterere ya hydrotalcite igizwe n'ibice byinshi bifite intera nini hagati ya 0.76-0.79nm, kandi ifite ubuso bunini bwihariye, butuma amatsinda yayo ya hydroxyl ashobora gukorana neza na hydrogen chloride kandi ikagira ingaruka nziza ku bintu bitera imbaraga.
Ingaruka mbi za hydrotalcite ni izi:
1. Ku bijyanye n'umweru wa mbere, hydrotalcite nta ngaruka igira ku kunoza ibara rya PVC haba ari ukwayo cyangwa mu guhuza na sisitemu ya calcium zinc. Iyo imaze gusaza mu itanura rishyushye rya 180 ℃, ibara ry'icyitegererezo rihinduka umutuku.
2. Ku bijyanye no kudahungabana kw'ubushyuhe butukura bwa Kongo, igikorwa kimwe cya hydrotalcite gishobora kongera igihe cyo kudahungabana k'ubushyuhe bwa PVC, kandi hamwe n'ubwiyongere bw'ingano y'inyongera, igihe cyo kudahungabana k'ubushyuhe bwa PVC kigaragaza icyerekezo cyiyongera, ariko ukwiyongera si ikintu gikomeye.
3. Iyo uruvange rwa hydrotalcite na sisitemu ya calcium zinc ikoreshejwe nk'ikintu gikomeza ubushyuhe, igihe cyo gukomeza ubushyuhe cya PVC kirarushaho kuba cyiza, kandi icyerekezo cyo kongera igihe cyo gukomeza ubushyuhe hamwe n'ubwiyongere bw'ingano nacyo kiragerwaho. Kubwibyo, dihydroxy metal hydroxides zigomba gushyirwa mu byiciro by'ibikoresho by'ubushyuhe by'igihe kirekire, bishobora kongera igihe cyo gukomeza ubushyuhe igihe kirekire cya PVC. Rero, iyo uvanze ibikoresho bikomeza calcium zinc, hydrotalcite ni kimwe mu bikoresho by'ingenzi.
