Kushandiswa
Potassium hydroxide, inozivikanwa se caustic potash kana potash lye, inowanikwa zvikuru mumhando mbiri dzemaindasitiri: yakasimba uye yemvura. Iyo yakasimba inoonekwa semaflakes machena kana magrey grey, zvidimbu, kana tsvimbo, nepo iyo mvura iri yero yakachenuruka. Hunhu hwayo hwemakemikari hwakafanana nehwe sodium hydroxide, ine alkalinity yakasimba uye corrosive. Inonyungudika nyore nyore mumvura uye inoburitsa kupisa kwakawanda, ichiratidzawo deliquescence, zvichireva kuti inogona kupinza hunyoro kubva mumhepo uye deliquescence, uye inogona kuita necarbon dioxide kuumba potassium carbonate. Kana yakanyungudutswa mumvura, doro, kana kurapwa neacid, inoburitsa kupisa kwakawanda. Mhinduro ye 0.1 mol/L ine pH ye13.5 (anhydrous). Ine chepfu iri pakati nepakati, ine avhareji yehuwandu hwerufu (mumuromo, makonzo) ye1230 mg/kg. Parizvino, potassium hydroxide inonyanya kushandiswa kugadzira potassium carbonate, potassium permanganate, nezvimwewo, uye inonyanya kushandiswa mumaindasitiri emakemikari, chikafu, mishonga, uye kurima.
Potassium hydroxide inonyanya kushandiswa sezvinhu zvekugadzira potassium salts, zvakaita se potassium permanganate ne potassium carbonate. Muindasitiri yemishonga, inoshandiswa kugadzira potassium borohydride, Antishutong, silybin, progesterone, uye testosterone propionate. Muindasitiri yechiedza, inoshandiswa kugadzira sipo ye potassium, mabhatiri e alkaline, uye zvizoro (zvakaita se cold cream, snow cream, uye shampoo). Muindasitiri yedhayi, inoshandiswa kugadzira madhayi e VAT, akadai se VAT blue RSN. Muindasitiri ye electrochemical, inoshandiswa pa electroplating, engraving, nezvimwewo. Muindasitiri yemicheka, inoshandiswa pakudhinda, kudhaya, kubleach, uye mercerizing, uye inoshandiswawo zvakanyanya sezvinhu zvikuru zvekugadzira ma fiber ekugadzira uye polyester fibers. Pamusoro pezvo, inoshandiswawo mu metallurgical heating agents uye degreasing deather, pakati pezvimwe zvinoshandiswa.
Kurongedza uye Kutumira
25KG/Drum kana zvichienderana nezvinodiwa nevatengi.
Ndezvezvinhu zvakajairika uye zvinogona kutumirwa negungwa nemhepo
Chengeta uye chengeta
Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.
