Alum hu ua ob ntsev ntsev, uas suav nrog hlau. Cov no yog octahedral crystals uas tau ntev tau siv nyob rau hauv cov tshuaj thiab kev lag luam. Cov tshuaj muaj pes tsawg leeg muaj xws li ib qho ntawm cov hlau alkali thiab cov hlau trivalent. Sulfate crystal hydrates yog tau los ntawm kev sib txuas cov ntsiab lus kub ntawm qee cov hlau, uas crystallize rau hauv alum thaum txias.

Potassium chromium alum: nws yog dab tsi thiab nws yog dab tsi

Dub liab doog octahedral crystals tsim poov tshuaj chromium alum - ib qho ntawm lawv cov neeg sawv cev tshaj plaws. Thaum cov tshuaj yog rhuab, ntsev crystals dehydrate thiab tig mus rau hauv lub teeb liab doog hmoov. Cov tshuaj aqueous muaj qaub saj. Lub npe ntawm cov muaju los ntawm lo lus "kvass", "qaub". Nyob ntawm cov xwm txheej, cov poov tshuaj chromium alum tuaj yeem hloov xim los ntawm cov ntshav sib sib zog nqus mus rau ntsuab tsaus. Piv txwv li, cov hmoov dub-violet hloov xim rau ntsuab thaum sov, thiab hloov mus rau ntshav thaum txias.

Ntawm no tau pom ib tsob ntoo qis rau hauvib qho kev daws ntawm poov tshuaj chromium alum, tom qab ziab nws nthuav tawm cov khoom refractory. Nyob rau hauv ancient Greece, poov tshuaj chromium alum yog lub npe hu rau hnav tawv nqaij, dyeing ntaub plaub thiab paj rwb ntaub thiab xov paj. Yog li ntawd, lawv tau siv los ua tus neeg sawv cev tanning nyob rau hauv cov txheej txheem ntawm xuas tes ua plaub hau, rau kev npaj ntawm emulsions thiab ua ib tug tanning fixer. Cov khoom zoo li no tau txiav txim siab los ntawm lawv lub peev xwm los tsim cov protein.

YPuas yog tshuaj alum

Aluminium-potassium alum yog hu ua cov xim tsis muaj kob lossis lawv cov hmoov dawb. Yooj yim soluble hauv dej thiab incompatible nrog tannins, mercury thiab lead ntsev. Thaum rhuab, lawv pib yaj, tig mus rau hauv ntsev, thiab tom qab cua sov ntxiv, tig mus rau hauv oxides, lawv tso sulfuric acid. Xws li crystalline hydrates tau pom siv nyob rau hauv kev npaj ntawm sulfuric acid.

YPotassium alum hauv tshuaj

Potassium alum kuj tau siv dav hauv tshuaj rau lub sijhawm ntev. Lawv nthuav tawm cov nyhuv hemostatic rau ntau qhov txhab thiab txiav. Qhov tseeb ntawm lawv siv los ntawm ancient alchemists thiab kws muag tshuaj nyob rau hauv cov teb chaws Europe thiab Asia kom txhob los ntshav yog paub. Tam sim no lawv tsim ib yam khoom nyob rau hauv daim ntawv ntawm alum mem hluav, uas muaj ib tug hemostatic, ziab thiab antiseptic nyhuv. Potassium alum kuj tseem siv rau hauv kev kho mob ntawm varicose leeg.

yuav alum qhov twg

Chromopotassium alum yog tshwj xeeb tshaj yog nrov nyob rau hauv kev lag luam textile, yog li muaj ntau manufacturers ntawm cov tshuaj. Qhov kev xaiv zoo heev. Internet muaj ntau lub lag luam,leej twg tsim cov poov tshuaj chromium alum, qhov twg koj tuaj yeem yuav lawv sai thiab yooj yim hnub no. Koj tuaj yeem xaiv lub ntim thiab hom ntim alum.

Storage condition

Cov khoom muaj peev xwm yuav tau los ntawm 200 g mus rau 25 kg, ntim rau hauv hnab yas lossis hnab, nrog rau cov hnab khoom siv tes ua. Qee zaum alum tau ntim rau hauv jars nrog iav tsaus. Cov neeg muag khoom muag yuav cov khoom siv lead ua hauv 1 kg pob rau tawv thiab textile ntau lawm. Cov khoom, vim nws cov yam ntxwv, yuav tsum tau muab cia rau hauv qhuav tej yam kev mob nyob rau hauv ib tug zoo-ventilated cheeb tsam nyob rau hauv cellophane los yog ntawv hnab. Yog tias koj tsis ua raws li cov xwm txheej yooj yim no, ces alum huab cua thiab poob nws cov khoom muaj txiaj ntsig. Potassium chromium alum khaws cia txog li 2 xyoos. Lawv kuj muaj nyob rau hauv daim ntawv ntawm ib tug deodorant los yog ib tug alum mem hluav, lawv yuav nyob rau hauv lub khw muag tshuaj nyob rau hauv txhua lub nroog los yog los ntawminternet.

Yuav ua li cas cov muaju tshwm

Potassium chromium alum hmoov yog xim tsaus liab doog, thiab nws cov tshuaj muaj xim ntsuab tsaus. Hmoov, dej thiab xov yog muab tso rau hauv ib khob. Lub thawv nrog cov tshuaj tov yog pleev xim rau dub, los ntawm qhov uas nws cov ntsiab lus tsis pom. Cov tshuaj muaj ib lub noob nrog ib tug tshuaj, uas yog muab tso rau hauv ib tug beaker rau loj hlob ib tug crystals. Crystals tshwm sim vim yog precipitate uas precipitates hauv kev daws. Tsis muaj xim poov tshuaj alum kuj tseem siv rau kev loj hlob siv lead ua. Ntxim nyiam ntxoov yog muab los ntawm kev sib xyaw ntawm cov poov tshuaj chromium thiab aluminium alum los ntawm lilac thiab paj yeeb rau ntshav.

Siv tshuaj

Croma-potassium thiab aluminium-potassium alum nyob rau hauv lub ntiaj teb niaj hnub no tau pom cov kev siv hauv qab no:

- raws li tus neeg sawv cev tanning rau zais;

- thaum hnav khaub ncaws;

- hauv kev yees duab;

- ua cov xim rau cov ceramics;

- hauv tshuaj ua hemostatic, tiv thaiv kev mob thiab astringent;

- hauv deodorant, antiperspirant thiab aftershave khoom;

- nyob rau hauv kev lag luam textile li mordant.

Lawv muaj txiaj ntsig zoo thaum ntxuav dej thiab ua cov tshuaj tua kab mob rau kev lag luam khoom noj. Potassium alum thiab potassium chromium alum tau pom lawv qhov chaw hauv kev lag luam thiab tshuaj niaj hnub no. Tab sis tseem, aluminium-potassium tseem muaj ntau dua. Ntau lub tuam txhab tam sim no muab onlinenpaj-ua potassium chromium alum hauv khw muag khoom thiab ncaj qha ntawm lub tuam txhab, qhov twg koj tuaj yeem yuav lawv txhua lub sijhawm.
