Imikoreshereze
Potasiyumu hidroksidi, izwi cyane nka potasiyumu cyangwa potasiyumu lye, iboneka ahanini mu buryo bubiri bw'inganda: ikomeye n'amazi. Imiterere yayo igaragara nk'uduce tw'umweru cyangwa tw'umukara woroshye, uduce, cyangwa uduti, mu gihe imiterere yayo ari amazi y'umuhondo werurutse. Imiterere yayo ya shimi isa n'iya sodiyumu hidroksidi, ifite alkalini ikomeye kandi irangirika. Ishongeshwa byoroshye mu mazi kandi irekura ubushyuhe bwinshi, kandi igaragaza ubushyuhe bwinshi, bivuze ko ishobora kwinjiza ubushuhe mu kirere no mu bintu bito, kandi ishobora gukorana na dioxyde de carbone ikarema potasiyumu karubone. Iyo ishongeshejwe mu mazi, alcool, cyangwa ivuwe na aside, irekura ubushyuhe bwinshi. Umuti wa 0.1 mol/L ufite pH ya 13.5 (anhydrous). Ifite uburozi buringaniye, hamwe n'igipimo cy'uburozi giciriritse (mu kanwa, mu mbeba) cya 1230 mg/kg. Muri iki gihe, potasiyumu hidroksidi ikoreshwa cyane mu gukora potasiyumu karubone, potasiyumu permanganate, nibindi, kandi ikoreshwa cyane cyane mu nganda za shimi, ibiribwa, imiti, n'ubuhinzi.
Potasiyumu hidroksidi ikoreshwa cyane cyane nk'ibikoresho fatizo mu gukora umunyu wa potasiyumu, nka permanganate ya potasiyumu na karubone ya potasiyumu. Mu nganda zikora imiti, ikoreshwa mu gukora borohydride ya potasiyumu, Antishutong, silybin, progesterone, na testosterone propionate. Mu nganda zikora urumuri, ikoreshwa mu gukora isabune ya potasiyumu, batiri za alkaline, n'amavuta yo kwisiga (nk'amata aconze, cream ya snow, na shampoo). Mu nganda zikora amarangi, ikoreshwa mu gukora amarangi ya vat, nka vat blue RSN. Mu nganda zikora amashanyarazi, ikoreshwa mu gushushanya, gushushanya, n'ibindi. Mu nganda zikora imyenda, ikoreshwa mu gucapa, gusiga amarangi, gusiba, no gushushanya, kandi ikoreshwa cyane nk'ibikoresho fatizo by'ingenzi mu gukora imigozi y'ubukorano n'imigozi ya polyester. Byongeye kandi, ikoreshwa no mu bikoresho bishyushya ibyuma no gukuraho amavuta mu ruhu, n'ibindi bikorwa.
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.
