Ingcaciso yeMveliso

I-Anhydrous Borax ikwabizwa ngokuba yi-sodium tetraborate, i-alpha orthorhombic crystal melting point 742.5℃,

Ubuninzi be-2.28g/cm3, i-β orthorhombic crystal melting point 664℃. Ubuninzi be-2.75, imbonakalo yi-white crystal

okanye ikristale efana neglasi engenambala, i-hygroscopicity enamandla, inyibilika emanzini, iGlycerin inyibilika kancinci kwi-methanol ukuze yenze isisombululo esinoxinzelelo lwe-13-16%. Isisombululo sayo samanzi si-alkaline encinci kwaye asinyibiliki kwi-alcohol.

I-Borax engenamanzi yinto engenamanzi efumaneka xa i-borax ishushu ukuya kuma-350 ~ 400℃, xa ibekwe emoyeni, inokufunxa umswakama ize ibe yi-borax decahydrate okanye i-borax pentahydrate.

QAPHELA: I-Borax yikristale ezinzileyo phantsi kweemeko eziqhelekileyo zokugcina kwaye ayisayi kusabela ngokweekhemikhali, kodwa ukuba ifunyenwe.

Ukuba imanzi, iya kukhupha ubushushu obuncinci ngamanzi ukuze ivelise i-borax decahydrate, ngoko ke kufuneka igcinwe kakuhle kwaye ingachatshazelwa kukufuma okanye ubushushu, kwindawo etshintshayo, kungenjalo iya kuhlangana. Ke ngoko, kuyimfuneko ukuqinisekisa ukupakishwa kakuhle.

Isicelo

1. Ezinye iimpawu ze-borax engenamanzi zifana ne-borax

2. I-borax engenamanzi isetyenziselwa iglasi esemgangathweni ophezulu, i-glaze, i-Welding flux, iintsimbi ezingezizo iintsimbi kunye ne-alloy fluxes, njl.njl....

3. I-borax engenamanzi yeyona nto iphambili ekulungiseleleni iikhompawundi ezine-boron. Phantse zonke iikhompawundi ezine-boron zinokwenziwa nge-borax.
