I-Boric acid

Incazelo emfushane:

Kuyimpuphu emhlophe ye-crystalline, enomuzwa obushelelezi futhi akukho phunga. Umthombo wayo we-acidic akumele unikeze ama-protons wodwa. Ngoba uBoron uyi-athomu elingameleli i-elektroni, lingangeza ama-hydroxide ion ama-molekyuli amanzi kanye nokukhipha amaprotoni. Ukusizakala kwale ndawo elahlekelwe nge-elektroni, ama-polyhydroxyl ahlanganisiwe (njenge-glycerol ne-glycerol, njll.) Angezwe ukwenza izakhiwo ezizinzile ukuqinisa i-acidity yazo.

I-oxalic acid iyi-acid ebuthakathaka. I-onizant yokuqala ionizant njalo i-Constant Ka1 = 5.9 × 10-2 kanye ne-Iginant-Order Oninization Constant Ka2 = 6.4 × 10-5. Kunokujwayelekile kwe-acid. Kungakuvimba isisekelo, uhlukanise inkomba, bese udedela ikhabhoni diokside ngokuxhumana nama-carbonates. Inokuncishiswa okuqinile futhi kulula ukufakwa kwi-carbon dioxide namanzi nge-ejenti oxdizing. Isixazululo se-acid potassium permanganate (KMNO4) singadilizwa futhi sincishiswe ku-2-lea mosese ion.

I-EverBright® 'LL futhi ihlinzeka ngezifiso: okuqukethwe / okumhlophe / izinhlayiya / phvalue / ukufakwa kombala / ukufakwa kwemininingwane / ukufakwa kwemikhiqizo ethile efanelekile ngezimo zakho zokusebenzisa, futhi zinikeze amasampula wamahhala.

Ukusetshenziswa Komkhiqizo

Ingilazi / fiberglass

Isetshenziselwa ukukhiqizwa kwengilazi ye-optical, ingilazi engamelana ne-acid, ingilazi ye-organoobarate kanye nezinye ingilazi ethuthukile ne-fiber yengilazi, kungathuthukisa ukumelana nokushisa kanye nokwenza izinto ezibonakalayo, kuthuthukise amandla okuncibilikisa. I-B2O3 idlala indima embaxambili yokwakheka kwenethiwekhi nokwakheka kwenethiwekhi ekwenziweni kwengilazi nengilazi yengilazi. Isibonelo, ekukhiqizweni kwe-Glass Fibre, ukuncibilika ukuncibilika kungenziwa ukwehliswa ukuze kusebenze umdwebo we-wire. Ngokuvamile, i-B2O3 inganciphisa ukubonakala, lawula ukwanda okushisayo, ukuvikela ukuvumela, ukuthuthukisa ukuqina kwamakhemikhali, futhi kuthuthukiswe ukumelana nokushaqeka kwemishini nokushaqeka kwe-thermal. Ekukhiqizweni kwengilazi lapho okuqukethwe okuphansi kwe-sodium kudingeka, i-boric acid ivame ukuxutshwa nama-sodium bortes (njenge-borax pentahydrate noma i-borax anhydrous) ukulawula isilinganiso se-sodium-boron engilazini. Lokhu kubalulekile ngengilazi ye-borossilte ngoba uBoron Oxide ukhombisa ubuhlalu obuhle endabeni ye-sodium ephansi ne-aluminium ephezulu.

Koqweqwe / ceramic

I-Enamel, imboni ye-ceramic yokukhiqizwa kwe-glaze, inganciphisa ukwanda okushisayo kwe-glaze, yehlise izinga lokuphumula le-glaze, ukuze uvikele ukuqhekeka nokushona, ukuthuthukisa i-luster kanye nokushesha kwemikhiqizo. Okwe-ceramic ne-koron oxide, i-flux enhle kanye nenethiwekhi eyakha umzimba. Ingakha ingilazi (emazingeni okushisa aphansi), yenza ngcono ukuvumelana nezimo ze-glaze engenalutho, ukunciphisa i-viscosity kanye nokungezwani komhlaba, ukuthuthukisa inkomba yokuqina, ukuthuthukisa ukumelana, ukuqina kokuqina, kuyingxenye ebalulekile ye-glaze eholayo. I-High Boron Frit ivuthwa ngokushesha futhi yakha i-glaze ebushelelezi ngokushesha, okulungele ukufaka imibala. Ku-Tile Frit ekhanyayo ekhanyayo, i-B2O3 yethulwa njenge-boric acid ukuqinisekisa isidingo sokuqukethwe se-sodium.

Umkhakha Wezokunakekelwa Kwezempilo

Kusetshenziswe ekukhiqizweni kwamafutha e-boric acid, amagciwane, astraisent, okulondolozayo nokunye.

I-Flame Retardant

Ukungezwa okubhalwe phansi ku-celluloid Ngakho-ke ilangabi ilangabi. I-Boric acid, yedwa noma inhlanganisela nge-borax, inomthelela okhethekile ekunciphiseni ukulahleka kokufakelwa kwe-celluluroid, izinkuni namathayi ekotini kumatilasi.

Inqwaba

Isetshenziswa njengezengezo kanye ne-cosolvent ekukhiqizeni i-boron yensimbi ukwenza insimbi ye-boron ibe nobulukhuni obuphezulu kanye nokukhohlisa okuhle okugoqekayo. I-Boric acid ingavimba i-oxidation yensimbi ye-welding yensimbi, i-brazing kanye nokwakha i-welding. Kuyinto ebonakalayo eluhlaza ye-Ferroboron Alloy.

Imboni yamakhemikhali

Kusetshenziswe ekukhiqizeni ama-bortes ahlukahlukene, njenge-sodium borohydride, i-ammonium hydrogen boRotungstate, potassium borohydride nokunye. Ekwenziweni kwe-nylon iphakathi, i-boric acid idlala indima ebambekayo e-oxidation of hydrocarbons futhi yandisa ama-esters ukwandisa isivuno se-ethanol, ngaleyo ndlela ivimbela ezinye i-oxidation ze-hydroxyl ukukhiqiza ama-ketones noma ama-hydroxici acid. Imboni yomanyolo ukukhiqizwa kwamakhandlela wick, boron aqukethe umanyolo. Isetshenziswa njenge-reagent yamakhemikhali yokuhlaziya yokulungiselela i-buffer kanye nemidiya ehlukahlukene yokuzalela i-haploid.
