I-Potassium Hydroxide

iPotassium hydroxide,luhlobo lweekhompawundi ezingaphiliyo, ifomula yeekhemikhali ye-KOH, sisiseko esiqhelekileyo se-inorganic, esine-alkaline enamandla, isisombululo se-0.1mol/L se-pH 13.5, esinyibilikayo emanzini, i-ethanol, esinyibilikayo kancinci kwi-ether, kulula ukufunxa amanzi emoyeni nakwi-deliquescent, sifunxa i-carbon dioxide size siye kwi-potassium carbonate, esetyenziswa kakhulu njengezinto eziluhlaza okwesibhakabhaka ukuvelisa ityuwa ye-potassium, ingasetyenziselwa ukufakelwa i-electroplating, ukuprinta kunye nokudaya.

iPotassium hydroxideZinokwahlulwa zibe ziintlobo ezimbini: umgangatho wokutya kunye nomgangatho wemizi-mveliso. Phakathi kwazo, i-99% ye-potassium hydroxide yomgangatho wemizi-mveliso isetyenziswa kakhulu kwiindawo ezahlukeneyo ezifana nesikhumba, ukwenza iphepha, ukuprinta kunye nokudaya, kunye nonyango lwelindle. , Iityuwa ezahlukeneyo ze-potassium, izithako ezongezelelweyo zokutya, ukucoca izikhongozeli zokucubungula ukutya, ukususa ityhefu yeChemicalbook kunye nezinye iindawo. I-sodium hydroxide kunye ne-potassium hydroxide zizinto eziluhlaza zesepha eyenziwe ngesandla, zonke ezi zi-alkali ezinamandla, kodwa emva kokugqiba isepha eyenziwe ngesandla, iba yisepha ngenxa ye-saponicization yeoyile namafutha, kwaye i-alkali iya kuqhubeka nokuncipha. Emva kwenyanga, ukuhla kwayo kwe-alkaline ukuya ngaphantsi kwe-9 akuyi kubangela umonakalo omkhulu eluswini.

Iimpawu zekhemikhali:Ikristale emhlophe yerhombic, iimveliso zoshishino zebhloko emhlophe okanye engwevu ekhanyayo okanye imilo yentonga. Inyibilika emanzini, inyibilika kwi-ethanol, inyibilika kancinci kwi-ether.

Isicelo:

1. Isetyenziselwa ukupeyinta nge-electroplating, ukukrola, ukuprinta amatye, njl.njl.

2. Izinto zokwenza ityuwa ye-potassium, ezifana ne-potassium permanganate, i-potassium carbonate.

3. Kwishishini lamayeza, isetyenziselwa ukuvelisa i-potassium boron eboring, i-bodystopstickness, i-sand hepatol alcohol, i-obsecoplasic testosterone, i-progesterone, i-chanantin, njl.

4. Kwishishini lokukhanya, isetyenziselwa ukuvelisa isepha ye-potassium, iibhetri ze-alkaline, izinto zokuthambisa (ezifana neqabaka elibandayo, intlama yekhephu kunye neshampu).

5. Kwishishini ledayi, isetyenziselwa ukuvelisa iidayi zokunciphisa umbala, ezifana nokunciphisa umbala oluhlaza okwesibhakabhaka.

6. Zisetyenziswa njengee-reagents zohlalutyo, ii-reagents ze-saponification, i-carbon dioxide kunye nee-absorbers zamanzi.

7. Kwishishini lempahla elaphu, isetyenziselwa ukuprinta nokudaya, ukufiphalisa, kunye nesilika, kunye nesixa esikhulu sezinto eziphambili zokwenza imicu yokwenziwa kunye nemicu yepolyester. Ikwasetyenziselwa ukwenza iidayi zemelamine.

8. Ikwasetyenziswa kwizinto zokufudumeza ezenziwe ngesinyithi kunye nokususwa kwesikhumba.

Ukupakisha, ukugcina kunye nokuthuthwa

Indlela yokupakisha:Iqinileyo ingapakishwa kwidrama yentsimbi enobukhulu obuyi-0.5 mm ivalwe ngokuqinileyo, ubunzima obupheleleyo bebhereli nganye abudluli kwi-100 kg; Ingxowa yeplastiki okanye ibhegi yephepha le-kraft elinezintlu ezimbini ngaphandle kwebhereli yentsimbi evulekileyo epheleleyo okanye ephakathi; Ibhotile yeglasi yomlomo enemisonto, ibhotile yeglasi yomlomo enesiciko sesinyithi, ibhotile yeplastiki okanye ibhakede yesinyithi (ijagi) ngaphandle kwebhokisi yomthi eqhelekileyo; Iibhotile zeglasi ezinemisonto, iibhotile zeplastiki okanye iibhakede zentsimbi ezifakwe kwiitini (iithini) ezigcwele ibhokisi yelattice esezantsi, ibhokisi yefiberboard okanye ibhokisi yeplywood; Ibhakede yentsimbi efakwe kwiitini (ithini), ibhakede yesinyithi (ithini), ibhotile yeplastiki okanye ipayipi yesinyithi ngaphandle kwebhokisi erhabaxa.
