Kagwiritsidwe Ntchito
Potassium hydroxide, yomwe imadziwika kuti caustic potash kapena potash lye, imapezeka makamaka m'mafakitale awiri: yolimba ndi yamadzimadzi. Yolimba imawoneka ngati ma flakes oyera kapena opepuka a imvi, zidutswa, kapena ndodo, pomwe yolimba ndi yachikasu chopepuka. Kapangidwe kake ka mankhwala ndi kofanana ndi ka sodium hydroxide, yokhala ndi alkalinity yamphamvu komanso kuwononga. Imasungunuka mosavuta m'madzi ndipo imatulutsa kutentha kwakukulu, komanso imawonetsa kusinthasintha, zomwe zikutanthauza kuti imatha kuyamwa mosavuta chinyezi kuchokera mumlengalenga ndi kusinthasintha, ndipo imatha kuchitapo kanthu ndi carbon dioxide kupanga potassium carbonate. Ikasungunuka m'madzi, mowa, kapena ikachiritsidwa ndi asidi, imatulutsa kutentha kwakukulu. Yankho la 0.1 mol/L lili ndi pH ya 13.5 (anhydrous). Ili ndi poizoni wocheperako, wokhala ndi mlingo wapakati wakupha (wakamwa, makoswe) wa 1230 mg/kg. Pakadali pano, potassium hydroxide imagwiritsidwa ntchito kwambiri popanga potassium carbonate, potassium permanganate, ndi zina zotero, ndipo imagwiritsidwa ntchito makamaka m'mafakitale a mankhwala, chakudya, mankhwala, ndi ulimi.
Potassium hydroxide imagwiritsidwa ntchito makamaka ngati zinthu zopangira mchere wa potaziyamu, monga potaziyamu permanganate ndi potaziyamu carbonate. Mu makampani opanga mankhwala, imagwiritsidwa ntchito popanga potassium borohydride, Antishutong, silybin, progesterone, ndi testosterone propionate. Mu makampani opanga kuwala, imagwiritsidwa ntchito popanga sopo wa potaziyamu, mabatire a alkaline, ndi zodzoladzola (monga kirimu wozizira, kirimu wa chipale chofewa, ndi shampu). Mu makampani opanga utoto, imagwiritsidwa ntchito popanga utoto wa vat, monga vat blue RSN. Mu makampani opanga magetsi, imagwiritsidwa ntchito popanga ma electroplating, engraving, ndi zina zotero. Mu makampani opanga nsalu, imagwiritsidwa ntchito posindikiza, kupukuta, kuyeretsa, ndi mercerizing, ndipo imagwiritsidwanso ntchito kwambiri ngati zinthu zopangira ulusi wopangira ndi ulusi wa polyester. Kuphatikiza apo, imagwiritsidwanso ntchito mu zotenthetsera zitsulo ndi kuchotsa mafuta pachikopa, pakati pa ntchito zina.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
