Tooj sulfate - Properties thiab cov kev siv

bluestone (Txwv tsis pub - tooj liab sulphate, tooj liab sulphate) yog ib tug hmoov muaj crystallites ntawm azure xiav. Nyob rau hauv cov xwm, nws tshwm sim nyob rau hauv daim ntawv ntawm cov mineral.

daim ntawv thov

Tooj - ib qho ntawm lub ib txoj lw ntsiab tsim nyog rau cov nroj tsuag. Nyob rau hauv ua liaj ua teb nws yog siv raws li ib tug Bordeaux kua (cov tshuaj ntawm tooj liab sulphate nyob rau hauv cov mis nyuj ntawm txiv qaub) ntawm phylloxera thiab ntau yam fungal kab mob. Tsis tas li ntawd, nws yog ib nyhuv lig rau kev ua pa thiab photosynthesis txheej txheem ntawm cov nroj tsuag.

Tooj sulfate kuj yog siv rau noob kev kho mob ua ntej cog, rhuav tseg li no rau noob noob pwm fungi.

Tooj sulfate (aqueous tov) yog siv los pab txhawb cov teebmeem ntawm to, raug tshem tawm plaster, vaj tse thiab masonry chaw nyob rau hauv cais lub ntsev, xeb me ntsis; muab refractory thaj chaw ntawm cov ntoo thiab tiv thaiv nws los ntawm lwj, impregnate ntoo nrog ib tug daws ntawm tooj liab sulfate.

Anhydrous tooj liab sulfate yog siv raws li ib tug dej qhia haus luam yeeb. Nyob rau hauv lub chaw soj nstuam nrog nws los ntawm qhuav lub ethanol thiab lwm yam.

Tooj sulphate yog siv nyob rau hauv qhov siv thiab ua mineral dyes, nyob rau hauv qhuav ntawm cellulose acetate fibers (uas muaj nyob rau hauv lub spinning tshuaj). Nws yuav siv tau los qhia zinc, magnesium thiab manganese nyob rau hauv stainless hlau thiab txhuas alloys.

Tooj sulphate yog siv nyob rau hauv cov zaub mov kev lag luam raws li ib tug preservative (khoom noj khoom haus additive) E519. Nyob rau hauv cov tsiaj - raws li mineral additive nyob rau hauv pub.

Nyob rau hauv cov tshuaj nws yog siv raws li ib tug astringent, antiseptic thiab cautery. Nyob rau hauv tus neeg mob ntawm lom dawb phosphorus pom zoo kom ntxuav lub plab 0.1 feem pua cov kua ntawm tooj liab sulfate.

Tooj sulfate electroplating siv raws li - nyob rau hauv txheej hlau cov khoom muaj tooj liab; nyob rau hauv lub metallurgical kev lag luam; ib tug npib tsib xee plating txheej txheem, thiab raws li feedstock nyob rau hauv qhov kev npaj ntawm lwm tebchaw.

Bluestone: Properties

Tooj sulfate - uas tsis yog-combustible, txais nplaim taws thiab. Heev hygroscopic. Nws tsis tsw, nws tsis muaj lub nws yog xim hlau saj. Heev soluble nyob rau hauv dej, nyob rau hauv diluted cawv, thiab ib tug concentrated hydrochloric acid tshuaj. Thaum rhuab, nws loses dej thiab yuav grey. Yog hais tias lub txias dej mus poob rau ntawm qhov grey hmoov, nws regains nws xiav xim. Tshab plaws lub cev qhuav dej ntawm ib tug kub ntawm 258C. Melts ntawm 1100C. Nyob rau hauv qhov nws los nyob rau hauv daim ntawv ntawm cov zaub mov chalcanthite, butit, halkokianit li al.

Crystal tooj liab sulfate

Zoo nkauj xiav siv lead ua tooj liab sulfate nws yog ib qho yooj yim loj hlob nyob rau hauv tsev (los ntawm txoj kev, tib txoj kev nws yuav ua tau kom loj hlob muaju ntawm ntshav hromokalievyh alum thiab tsis muaj kob - ntawm rooj ntsev). Tag nrho cov txheej txheem yuav siv ob peb lub lis piam.

Mus ua hauj lwm xav tau hlau, xov, lub hwj iav thiab tooj liab sulphate (los yog lwm yam xaiv ntsev). Npaj ib co feeb meej ntsev tov: pab txhawb, stirring tsis tu ncua, ntsev dej mus rau hauv lub can kom txog thaum nws nres kom txog thaum yaj. Ces tus sib tov twb sov me ntsis rau yaj yam ntsev, uas bank (los yog iav) yog muab tso rau hauv ib lub lauj kaub ntawm rhuab dej.

Lub concentrated tshuaj li tau twb poured mus rau hauv ib lub beaker thiab tshem tawm muaj los ntawm txoj kev hlau jumpers me me siv lead ua los ntawm cov tib ntsev, nyob rau ib txoj hlua by immersing nws nyob rau hauv cov tshuaj. Thaum no crystallite (noob), thiab koj xav kom peb loj hlob ib tug siv lead ua.

Beaker nrog cov tshuaj muab nyob rau hauv qhov tseeb nyob rau hauv ib tug sov so qhov chaw thiab soj ntsuam raws li tus siv lead ua hlob. Thaum nws yuav txaus loj, nws yog muab tshem tawm los ntawm cov tshuaj, obsushivayut ntawv so tes los yog mos daim ntaub, txiav lub xov thiab npog nws nrog cov kua roj vanish (thiaj li tsis txhob "yaig" nyob rau hauv cov huab cua).

Cov uas ua siv lead ua yog heev uas zoo sib xws rau ib tug pob zeb diamond.
