    Product Description

    Anhydrous borax / sodium tetraborate tsos yog dawb crystalline lossis tsis muaj xim vitreous siv lead ua.Lub melting point ntawm alpha orthorhombic siv lead ua yog 742.5 ℃, thiab qhov ceev yog 2.28;Lub melting point ntawm beta orthorhombic siv lead ua yog 742.5 ℃, thiab qhov ceev yog 2.28.Nws muaj zog hygroscopicity thiab tuaj yeem soluble hauv dej thiab glycerol.Nws maj mam yaj hauv methanol los tsim cov tshuaj nrog ib qho concentration ntawm 13-16%.Cov tshuaj aqueous yog qaug zog alkaline, insoluble hauv cawv.Anhydrous borax yog cov khoom tau txais thaum borax yog rhuab mus rau 350-450 ℃.Thaum muab tso rau hauv huab cua, nws tuaj yeem hloov hygroscopically rau hauv borax decahydrate lossis borax pentahydrate.

    Ib qho tseem ceeb ntawm boric oxide rau glazes.Anhydrous borax yog tsim los ntawm kev hlawv lossis fusing hydrated borax.Nws yog li no muaj me me los yog tsis muaj dej ntawm crystallization thiab tsis rehydrate nyob rau hauv ib txwm cia tej yam kev mob.Anhydrous borax yog dej soluble, tab sis tseem ceeb tsawg dua li raw borax (hauv cov kua dej nws tuaj yeem muab qeeb tso tawm ntawm boron).

    Cov khoom no tsis puff los yog o thaum lub sij hawm melting (tsawg poob ntawm cov hmoov nyob rau hauv kilns uas muaj zog drafts), thiab melts yooj yim dua (qhov o nyob rau hauv lwm yam ntaub ntawv yuav tsim ib tug ntxeem tau lub xeev nrog ib tug rwb thaiv tsev yam uas slows melting).Anhydrous borax yog ib qho zoo heev iav yav dhau los, nws tsis puff los yog o thaum lub sij hawm yaj yog li tsawg dua cov teeb meem tshwm sim.

    Cov khoom siv no yog siv los ua qhov chaw ntawm B2O3 hauv kev tsim khoom ntawm ntau hom iav borosilicate iav, nrog rau cov iav kub thiab tshuaj tiv thaiv, tsom iav qhov muag, qhov muag qhov muag, cov thawv kho mob thiab cov tshuaj pleev ib ce, hollow microspheres thiab iav hlaws.Nws muaj qhov ntom ntom ntau dua thiab melts sai dua li cov ntaub ntawv nyoos ntawm borax.Nws kuj muab ib qhov chaw ntawm sodium.

    Kev siv borax

    Borax yog siv nyob rau hauv ntau yam khoom siv ntxhua khaub ncaws hauv tsev thiab tu, suav nrog 20 Mule Team Borax ntxhua khaub ncaws, Boraxo hmoov xab npum, thiab qee cov tshuaj ntxuav hniav dawb.

    Borate ions (feem ntau muab raws li boric acid) yog siv nyob rau hauv biochemical thiab chemical laboratories los ua buffers, piv txwv li rau polyacrylamide gel electrophoresis ntawm DNA thiab RNA, xws li TBE tsis (borate buffered tris-hydroxymethylaminomethonium) los yog tus tshiab SB tsis (BBS buffer) borate buffered saline) nyob rau hauv cov txheej txheem txheej.Borate buffers (feem ntau ntawm pH 8) kuj tseem siv los ua cov kev daws teeb meem zoo sib xws hauv dimethyl pimelimidate (DMP) raws li kev sib txuas sib txuas.

    Borax raws li qhov chaw ntawm borate tau siv los ua kom zoo dua ntawm kev sib koom ua ke muaj peev xwm ntawm borate nrog lwm cov neeg ua haujlwm hauv dej los tsim cov ions nyuaj nrog ntau yam tshuaj.Borate thiab ib lub txaj zoo polymer yog siv los chromatograph uas tsis yog-glycated hemoglobin txawv ntawm glycated hemoglobin (chiefly HbA1c), uas yog ib qho qhia txog kev mob ntshav qab zib mellitus ntev.

    Kev sib xyaw ntawm borax thiab ammonium chloride yog siv los ua cov dej ntws thaum vuam hlau thiab hlau.Nws txo qis qhov melting point ntawm pliaj pliaj oxide (scale), cia nws khiav tawm.Borax kuj tseem siv cov dej sib tov ua cov kua dej thaum siv cov khoom siv hlau xws li kub lossis nyiaj, qhov uas nws tso cai rau cov molten solder kom ntub cov hlau thiab ntws sib npaug rau hauv kev sib koom ua ke.Borax kuj yog ib qho zoo flux rau "pre-tinning" tungsten nrog zinc, ua rau tungsten mos-solderable.Borax feem ntau yog siv los ua flux rau forge vuam.

    Nyob rau hauv artisanal kub mining, borax yog qee zaum siv los ua ib feem ntawm cov txheej txheem hu ua borax txoj kev (raws li flux) txhais tau tias tshem tawm qhov xav tau rau cov tshuaj lom mercury hauv cov txheej txheem kub rho tawm, txawm hais tias nws tsis tuaj yeem hloov mercury ncaj qha.Borax tau tshaj tawm tias siv los ntawm cov miners kub hauv thaj chaw ntawm Philippines hauv xyoo 1900.Muaj pov thawj tias, ntxiv rau kev txo cov kev cuam tshuam ib puag ncig, txoj kev no ua tiav zoo dua kub rov qab rau cov ore uas tsim nyog thiab tsis tshua muaj nqi.Txoj kev borax no yog siv nyob rau sab qaum teb Luzon hauv Philippines, tab sis cov miners tsis kam txais yuav nws nyob rau lwm qhov vim tsis nkag siab zoo.Txoj kev kuj tau nce qib hauv Bolivia thiab Tanzania.

    Cov roj hmab polymer qee zaum hu ua Slime, Flubber, 'gluep' lossis 'glurch' (los yog hu ua Silly Putty, uas yog raws li silicone polymers), tuaj yeem ua los ntawm kev sib txuas ntawm polyvinyl cawv nrog borax.Ua flubber los ntawm polyvinyl acetate-raws li cov kua nplaum, xws li Elmer's Glue, thiab borax yog ib qho kev ua qauv qhia kev tshawb fawb.

    Lwm yam kev siv suav nrog:

    ●Cov khoom xyaw hauv enamel glazes
