Chii chibooreso? Borax: kushanda. Shoko rokuti "boora"

Vakawanda makemikari anoshandiswa munhu akasiyana-siyana maindasitiri. Idzi dzinosanganisira boora. It rinoshandiswa maindasitiri, zvokurima, engineering, mushonga, upenyu uye zvichingodaro. N. chii boora? chicherwa ichi, rinonziwo tinkalom kana yavaibvisa borate ane nemamwe ehupfumi.

tsananguro

Saka chii boora? fuma iyi crystallizes munyika monosimmetricheskoy hurongwa. Chitarisiko Its afanane pembiru augite. Translated kubva Persian zita rayo rinoreva "chena." Transparent chibooreso, kushandiswa iri zvinogoneka pashure nokungwarira mukugadzirisa crystals, anenge Hauoneki kana zvishoma grayish. It kunoratidzwa ne chipenye zvinozipa, alkaline kuravira. The fuma iri soluble mumvura. Nokuti chinangwa ichi, kazhinji 1 chikamu tinkala kutora 14 zvikamu mvura. Utsotso nguva vaiona ndiro chicherwa 60,8 ° C. Pamusoro kubvunda blowtorch murazvo kupendwa mu tsvuku ruvara, asi fuma pachayo kana ichichinja kuita Hauoneki girazi.

Makemikari anoumba borax

Ngatitarisei zvinotaura chibooreso tichitarisa kemisitiri. The remubatanidzwa wenyika payakavakirwa: Na ₂ B ₄ O _7. Kazhinji, riripo sezvo crystalline Na ₂ B ₄ O ₇ • 10 ₂ O, izvo unoenderana 16% kubva hydroxide, 37% boric asidhi uye 47% mvura. Borax ndiye yakatsvuka zvinhu achigadzirira yeimwe zviri mukati. Quality pehurumende zvinhu GOST 8429-77. In kutengeswa yavaibvisa tetraborate (borax) iri yaipiwa somunhu chena crystalline upfu, vane unhu zvinoenderana siyana okunze uye nemakemikari kwomwoyo. The chigadzirwa anouya zvidzidzo zviviri: A (vakawanda chikamu borax haidereri pane 99,5%) uye B (94%). Uyewo, rine carbonates, sulfates, kutungamirira uye Arsenic.

Mining uye kugamuchira drills

Izvi zvinhu kakawanda zvikaramba pasi zvakasikwa ezvinhu. Chii chibooreso munyika yakafara pfungwa shoko? chicherwa ichi ndohwaJehovha mukirasi borates. Zviri makemikari precipitate kuti kupwa munyu madhamu. MuEurope, nefuma mu mubvunzo wokutanga akazviratidza mushure akawanikwa ari Tibetan munyu madhamu. Kubva ipapo mamwe zita raro - tinkal. Rich shava vamwe California kudzika makungwa, apo inobereka crystals nekaupenyu guru. Sales anogona kusangana hwokugadzira uye zvokudya yavaibvisa tetraborate.

Muna 1748, borax kubva boric asidhi uye pasoda kokutanga yakagamuchira kemisiti French Enuvil. Uye munguva yedu, dzimwe makambani munyaya pagadzirwe chakagadzirwa yavaibvisa tetraborate decahydrate. Borax maoko chingawanikwa neutralizing boric asidhi pamwe yavaibvisa carbonate, pamwe unozotevera kwemvura pakati musanganiswa uye filtration. Izvi zvinobva makemikari maitiro: Na ₂ C0 ₃ + 4h ₃ BO ₃ = 6 ₂ O + CO ₂ + Na ₂ B ₄ 0 _7. The mudziyo rinogadzirirwa munhu pasoda mhinduro uye nenharo kuti 95-100? C, unomutsa nguva dzose. Ipapo kudurura boric acid. Kuti inotoda foamed, zvinonzi yebhasera migove diki. The reshiyo inofanira kuva vakadaro kuti mhinduro ine 16-20% Na ₂ B ₄ 0 ₇ uye 0,5-1,0% Na ₂ C0 _3. Musanganiswa akanga yakabikwa kwemaminitsi 30, yakasvinwa uye dzaserera kupa crystals. Chakagadzirwa chicherwa kemesitiri zvakasiyana dzinongoitika rhombohedral crystals uye unotora shomanana mvura. Unogona chete kushandiswa hwokugadzira uye zvokurapa mafomu.

Borax: maindasitiri mafomu

The hwokugadzira kushandiswa ichi acho zvikuru siyana. Borax chinhu chinoumba achichinja nokuda Welding pamusoro nesimbi, kusanganisira anokosha. Sechikamu mhosva inoshandiswa girazi kugadzirwa, enamels, glazes, seinokonzera Boron oxide hunokosha. Kushandiswa kwaro nokuti zvaAtemisi antiseptics, zvipembenene, uye sezvo zvisaora iri kubudiswa mbishi matehwe. Borax kudiwa electrolytes mune simbi.

Tinkal imwe feedstock iri zvaAtemisi yavaibvisa perborate, inova huru chezvinonhuwira yakachena-bleaching sipo upfu iri chakaita zvokugadzirwa nevezvenhau. Kuvandudza zvivako yokuswerochenesa uye kuramba zvinodiwa viscosity, ph, achipa kugona kuumba emulsion zvinosanganisira yavaibvisa tetraborate mumhuri uye mumaindasitiri kuchenesa nevasori, uye natirok polishes. Borax rinoshandiswa nokuda kwezvifananidzo zvaAtemisi lubricants, akamedura zvinwiwa; uye chinokosha zvaAtemisi antifreeze, nokuti, achiuya neZvapupu simbi ngura inhibitor anoumba kunzwisisa akakura. Rinoshandiswa nenzira zvaAtemisi adhesives siyana.

Kushandiswa borax mumba

chicherwa ichi kare nevanhu dzinongoitika cleanser. Hammer borax rinoshandiswa kuti vakarongeka kuchenesa utsanana michina. Ungada chimbuzi rako richibwinya? No mubvunzo: zvichava zvakakwana kudira mariri 1 cup zvevhu chicherwa uye siya husiku. Plumbing vakachenesa aine bhurasho mangwanani, unogona kubvisa chero zvakaoma goho yakasviba. Munzvimbo aqueous mhinduro kuti borax (2 h. L. 0.5 L mvura) somunhu sipo.

Izvi fuma rakasiyana inogona kushandiswa kudzora inda uye mapete. Somuenzaniso, munzvimbo umo chisvetasimba nguva akadurura borax upfu. Haufaniri kunetseka pamusoro chiutsi: mune diki zvakawanda hazvina kukuvadza vanhu nemhuka.

Kuti kurwisa hosha kugadzirira gobvu namatidza remvura uye borax. Its kupararira pamusoro zvavhuvha nomumativi siya kwemaawa 12-24. Dried Pasta kutsvaira bhurasho usukwe vakasara mvura. chokushandisa Izvi chete akakodzera tichishandisa mvura nemishonga hukawanika. Mukuwedzera, chibooreso inoshandiswa pavanoparidza starch nokuda pakurapa uketani uye hand cuffs. Oshandisa mune wash zvinhu yaigadzirwa nemvere (1 hr. L. 1 fő mvura). Sei? Very nyore: kuti nguo dzakapfavirira.

Inoshandiswa mukurapa

Yavaibvisa tetraborate rinoshandiswa sezvo akambozvishandisa kuuraya utachiona kuti gargles, douches, ganda kurapwa uye kunanzvana mhango. Nokuti chinangwa ichi, glycerol (20%) kana aqueous mhinduro kuti borax. Doro zvingaitwa hakuwaniki, nokuti pfuma iri insoluble doro. Ramba borax anofanira zvakasimba mudziyo rakavharwa uye pasigasvikirwi vana, sezvo akawanda uye yakakwirira kuwanda ingava inokuvadza utano.
