Tšebeliso
Potassium hydroxide, e tsejoang haholo e le caustic potash kapa potash lye, e teng haholo-holo ka mefuta e 'meli ea indasteri: e tiileng le e metsi. Sebopeho se tiileng se hlaha e le matheba a masoeu kapa a bohlooho bo bobebe, likotoana, kapa lithupa, ha sebopeho sa mokelikeli e le mokelikeli o mosehla o moputsoa. Litšobotsi tsa eona tsa lik'hemik'hale li tšoana le tsa sodium hydroxide, e nang le alkalinity e matla le ho bola. E qhibiliha habonolo ka metsing 'me e ntša mocheso o mongata, hape e bontša deliquescence, ho bolelang hore e ka monya mongobo habonolo moeeng le deliquescence, 'me e ka arabela le carbon dioxide ho etsa potassium carbonate. Ha e qhibiliha ka metsing, joala, kapa e phekoloa ka asiti, e ntša mocheso o mongata. Tharollo ea 0.1 mol/L e na le pH ea 13.5 (anhydrous). E na le chefo e itekanetseng, ka tekanyo e bolaeang e mahareng (ka molomo, rat) ea 1230 mg/kg. Hona joale, potassium hydroxide e sebelisoa haholo ho etsa potassium carbonate, potassium permanganate, jj., 'me e sebelisoa haholo-holo indastering ea lik'hemik'hale, lijo, meriana le temo.
Potassium hydroxide e sebediswa haholoholo e le thepa e tala bakeng sa tlhahiso ya matswai a potassium, jwalo ka potassium permanganate le potassium carbonate. Indastering ya meriana, e sebediswa ho hlahisa potassium borohydride, Antishutong, silybin, progesterone, le testosterone propionate. Indastering ya mabone, e sebediswa ho hlahisa sesepa sa potassium, dibetri tsa alkaline, le ditlolo (jwalo ka cold cream, snow cream, le shampoo). Indastering ya dae, e sebediswa ho hlahisa didae tsa vat, jwalo ka vat blue RSN. Indastering ya dikhemikhale tsa motlakase, e sebediswa bakeng sa ho plating ka motlakase, ho betla, jj. Indastering ya masela, e sebediswa bakeng sa ho hatisa, ho daya, ho soeufatsa le ho mercerizing, mme e boetse e sebediswa haholo e le thepa e ka sehloohong e tala bakeng sa ho etsa difaeba tsa maiketsetso le difaeba tsa polyester. Ho feta moo, e sebediswa hape ho di-heating agents tsa metallurgical le ho tlosa mafura letlalong, hara dikopo tse ding.
Ho paka le ho Romela
25KG/Moropa kapa ho ya ka ditlhoko tsa bareki.
Ke ea thepa e tloaelehileng 'me e ka tlisoa ka leoatle le moea
