Imikoreshereze
Aside dehydroasetic (DHS) ikoreshwa nk'iy'ituma ibintu bihora bihindagurika mu bwiza no mu buvuzi bitewe n'imikorere yayo yo kurwanya udukoko n'uburozi bw'udukoko, nk'inyongera ku bintu bikomeza ubuziranenge bwa PVC no mu gukora imiti y'amatungo.
Geogard (R) 111a ikoreshwa mu kubungabunga ubwiza ishingiye kuri aside dehydroasetic (DHA) bityo ikaba yemewe n'inzego zikomeye zishinzwe kugenzura ubwiza, ubwiherero n'impumuro nziza ku isi yose kugira ngo ikoreshwe mu bikoresho byo kwisiga no kwita ku buzima bwite bw'umuntu.
Geogard (R) 221 preservative ishingiye kuri aside dehydroacetic (DHA) na benzyl alcohol, bityo ikaba yemewe n'inzego zikomeye zishinzwe kugenzura ubwiza, ubwiherero n'impumuro nziza ku isi yose kugira ngo ikoreshwe mu bikoresho byo kwisiga no kwita ku buzima bw'umuntu ku giti cye.
Geogard (R) 361 ishingiye ku bice bitandatu bihuza ibintu, byose byemerwa ku rwego rw'isi yose: aside dehydroacetic (DHA); aside salicylic; aside benzoic; phenoxyethanol; benzyl alcohol; na benzethonium chloride.
imiti yica udukoko, imiti irwanya udukoko
aside dehydroacetic ni umuti urinda indwara kandi ufite ubushobozi buke bwo gutuma umubiri urushaho kumva neza. Iyi ni aside idakomeye ikoreshwa nk'ikintu cyangiza ibihumyo na bagiteri mu kwisiga. Kuba hari ibintu by'umwimerere bigabanya ubushobozi bwayo. Ntabwo itera ubwivumbure cyangwa allergie iyo ikoreshejwe ku ruhu.
Aside dehydroasetic (DHA) ni ifu irinda ubushyuhe ifite ubushobozi bwo gushonga munsi ya garama 0.1 muri garama 100 z'amazi kuri dogere selisiyusi 25. Ishobora kugira ingaruka zitandukanye ku binyabutabire, ibyo bigatuma igira akamaro mu bikorwa byinshi. Ikoreshwa kuri 0.01–0.5% mu gukumira gukura kwa mikorobe mu biribwa bitandukanye. Ikoreshwa ku bijumba byaciwe cyangwa byaciwe, nta kigero kirenze 65 ppm gisigaye mu bijumba byateguwe cyangwa ku bijumba.
Gupakira no Kohereza
25KG/Ingoma cyangwa nk'uko umukiriya abikeneye.
Ni iy'ibicuruzwa rusange kandi ishobora gutangwa binyuze mu nyanja no mu kirere
Bika kandi ubibike
Igihe cyo kubika: Amezi 24 uhereye igihe byakorewe mu ipaki y’umwimerere idafunguye, bibitswe ahantu hakonje kandi humutse, kure y’izuba ryinshi, amazi.
Ububiko bufite umwuka uhagije, Butuma ibintu bishya bishyuha, butandukanyijwe n'ibikomoka kuri okiside, aside.
