Txhua tus neeg yuav pom tseeb hauv lub txee tshuaj xws li cov tshuaj orthoboric acid. Ntau tus siv los ua tshuaj pleev ib ce lossis tshuaj. Tab sis nws tseem ceeb heev kom nkag siab tias qhov sib txawv ntawm boric cawv thiab kua qaub yog dab tsi. Nws yog ib qho tsim nyog kom nkag siab cov ncauj lus no kom tsis txhob muaj teeb meem kev noj qab haus huv thiab siv txhua yam khoom siv rau nws lub hom phiaj.
Qhov no yog dab tsi?
Orthoboric acid feem ntau yog cov khoom siv crystalline, los ntawm qhov kev daws teeb meem tom qab npaj. Cov tshuaj no yog ib qho tsis muaj zog acid. Cov tshuaj formula ntawm orthoboric acid yog: H3BO3. Cov tshuaj no muaj tsawg solubility hauv dej txias. Tab sis lub solubility ntawm orthoboric acid nce thaum rhuab. Piv txwv li, lub solubility ntawm no compound ntawm 0 degrees Celsius yog 2.66 g ib 100 g ntawm dej, thiab nyob rau ntawm ib tug kub ntawm 100 degrees Celsius, nws twb muaj peev xwm yaj 39.7 g ntawm cov khoom.
Thiab kuj solubilityorthoboric acid nyob ntawm hom hnyav. Yog hais tias cov no yog cov ntxhia acids, ces cov compound reacts tsis zoo nrog lawv, thiab, piv txwv li, nws dissolves zoo dua nyob rau hauv ntsev tov. Orthoboric acid tuaj yeem yaj hauv monohydric thiab polyhydric cawv. Thiab kuj zoo heev cov kuab tshuaj rau cov compound no yog acetone thiab pyridine. Nws yuav tsum tau ntxiv tias orthoboric thiab boric acid yog cov npe sib txawv rau tib yam khoom.
Nyob hauv ntuj
Orthoboric acid tshwm sim hauv cov ntxhia hu ua "sassoline". Tsis tas li ntawd, qhov sib xyaw no tau pom nyob rau hauv cov dej thermal. Orthoboric acid yog tau los ntawm lawv. Rau qhov no, extraction yog nqa tawm siv cawv. Thiab lwm txoj hauv kev tau txais kuj tseem ua tau, piv txwv li, siv sorbents ntawm inorganic thiab organic xwm.
Ionic daim ntawv
Orthoboric acid muaj zog electrolytic tsis muaj zog. Yog hais tias ib qho hluav taws xob tam sim no siv rau kev daws hauv dej nrog kev sib txuas, ces electrolytic dissociation rau hauv ions yuav tshwm sim. Qhov sib npaug ntawm cov txheej txheem no yog: H3BO3 ⇆ 3H+ + BO 3 3-. Hauv qhov no, BO33- yog cov kua qaub residue ntawm orthoboric acid. Vim qhov kev sib cais no thiab muaj cov kua qaub seem, cov kua qaub tuaj yeem tsim cov ntsev nrog cov ntsiab lus yooj yim.
Daim ntawv thov
Orthoboric acid yog dav siv hauv ntau yam. Hauv kev lag luam, nws yog siv los tauborosilicate iav. Nws lub ntsiab feature yog tias nws muaj kev ruaj ntseg zoo nyob rau hauv tej yam kev mob ntawm ib tug ntse hloov nyob rau hauv kub.
Thiab tseem yog qhov sib xyaw no yog siv los tsim ntau yam xim thiab cov kua roj vanish, cement, dyes, tshuaj pleev ib ce, tshuaj, thiab lwm yam. Tsis tas li ntawd, orthoboric acid yog siv los ua cov tshuaj tiv thaiv corrosion, uas tsim nyog hauv ntau lub lag luam. Thiab kuj acid yog siv los ua chiv rau cov nroj tsuag.
Qhov kev sib xyaw no kuj tseem siv rau hauv kev xyaum ua haujlwm: nws yog siv los npaj cov kev daws teeb meem. Orthophosphoric acid feem ntau siv rau hauv kev kho mob, vim nws muaj cov tshuaj tua kab mob. Yog vim li cas thiaj muaj ntau hom kua qaub tso tawm. Ntxiv nrog rau kev daws teeb meem yooj yim, nws tuaj yeem yog tshuaj pleev, hmoov, cream, ntau yam pastes. Acid kuj pom nws daim ntawv thov hauv kev lag luam khoom noj. Koj tuaj yeem pom nws los ntawm tus lej E284. Cov kua qaub yog siv los ua cov khoom noj.
siv kho mob
Orthoboric acid yog siv los kho ntau yam kab mob, nws cov txiaj ntsig tseem ceeb yog cov tshuaj tua kab mob. Cov tshuaj muaj ntau hom kev tso tawm. Tab sis txhua yam tshuaj, nthuav tawm hauv nws daim ntawv, yuav tsum tau siv thiab khaws cia kom raug. Piv txwv li, daim ntawv hmoov yuav tsum tau npaj ua ntej siv.
Siv orthoboric acid los kho mob conjunctivitis, yog tias feem ntau ntawm daim tawv nqaij raug cuam tshuam los ntawm cov kab mob sib kis,nrog pob ntseg thiab mucous daim nyias nyias.
Siv Tshuaj Tiv Thaiv Kab Mob
Orthoboric acid yog ib qho kev pab zoo hauv kev tawm tsam pob txuv. Ntxiv mus, tus nqi ntawm cov cuab yeej no tsawg heev. Tab sis ua ntej siv cov kua qaub no rau lub hom phiaj tshuaj pleev ib ce, koj yuav tsum sab laj nrog tus kws kho mob tshwj xeeb thiab xyuas kom meej tias tsis muaj rhiab heev rau cov ntsiab lus ntawm cov tshuaj kom tsis txhob ua xua tshwm sim yav tom ntej.
Kho pob txuv, so cov tawv nqaij cuam tshuam nrog me me ntawm orthoboric acid siv cov paj rwb ncoo. Thiab koj tuaj yeem taw tes rau cov kua qaub nrog paj rwb swab. Cov cuab yeej no yog qhov zoo rau kev daws cov pob txuv tsis xav tau, vim nws ua rau daim tawv nqaij qhuav me ntsis, nthuav tawm cov kab mob bactericidal thiab txo qhov mob hnyav.
siv dej ntxhia
Kho cov dej ntxhia muaj ntau cov ntxhia hauv cov ntsiab lus uas tib neeg lub cev xav tau ntau heev. Nws yog tsim nyog sau cia tias lawv yuav tsum tau siv tshwj xeeb rau kev siv tshuaj, lossis tsis tu ncua kom muaj kev noj qab haus huv.
Tab sis ua ntej siv cov dej tshuaj, nws yuav tsum sab laj nrog cov kws tshaj lij. Ntxiv nrog rau cov khoom xws li iodine, hlau, ntau yam organic tebchaw, cov dej ntxhia kuj muaj boron, uas hloov mus rau boric acid. Orthoboric acid nyob rau hauv cov dej ntxhia tuaj yeem muaj nyob rau hauv qhov ntau ntawm 35 mus rau 60 mg ib liter dej.
Cov tshuaj no tau siv dav hauv tib neeg lub neej, tab sis yuav tsum tau ua tib zoo saib xyuas kom nws tsuas yog siv rau kev noj qab haus huv xwb.
