Hauv kev tshawb fawb thiab kev siv cov tshuaj inorganic phosphorus, qhov tsos yog ib qho tseem ceeb rau kev txheeb xyuas ua ntej thiab kev txiav txim siab ntawm cov khoom siv hauv lub xeev. Phosphorous acid, raws li ib tug nquag siv phosphorus-raws li tshuaj, muaj ib tug kuj sib txawv thiab ruaj khov daim ntawv, muab ib tug ncaj qha siv rau kev txheeb xyuas thiab kev tswj zoo nyob rau hauv ntau lawm, cia, tsheb thauj mus los, thiab siv.
Nyob rau hauv chav tsev kub, phosphorous acid feem ntau tshwm sim raws li dawb crystalline los yog dawb hmoov hmoov. Crystalline phosphorous acid particles have clear outlines, a dense crystal structure, and a high refractive index, exhibiting a uniform bright white color under natural light or laboratory light sources, without obvious impurities or unusual spots. Powdered phosphorous acid yog tsim los ntawm cov khoom zoo, muaj kev ntxhib los mos, zoo flowability, thiab muaj zog xim sib xws, thiab feem ntau tsis muaj cov khoom tsis zoo. Txawm hais tias crystalline los yog hmoov daim ntawv, nws cov xim yog dawb huv, ib tug yam ntxwv stemming los ntawm cov tsis tu ncua ntawm nws cov qauv molecular thiab lub optical reflection zog nyob rau hauv nws siab -purity xeev.
Lub crystal morphology ntawm phosphorous acid sib txawv me ntsis nyob ntawm crystallization tej yam kev mob, feem ntau tshwm raws li koob -zoo li, columnar, los yog phaj-zoo li aggregates. Cov pob zeb siv lead ua yog du nrog cov npoo ntse, thiab cov duab geometric tsis tu ncua tuaj yeem pom nyob rau hauv lub tshuab tsom. Qhov no niaj hnub siv lead ua morphology tsis tsuas yog qhia txog kev txiav txim ntawm nws cov molecules tab sis kuj, rau qee qhov, kwv yees nws qhov kev sib cais thiab kev ruaj ntseg hauv cov kuab tshuaj. Raws li kev nthuav dav, cov khoom siv hmoov qhia tau hais tias muaj qhov sib txawv me me me me uas tsis muaj agglomeration tseem ceeb, uas yuav pab tswj cov tshuaj ntau npaum li cas thaum tsim thiab sib xyaw.
Nyob rau hauv cov nqe lus ntawm kev ntxhib los mos, cov khoom phosphorous acid xav tias qhuav rau qhov kov, muaj nruab nrab hardness, thiab nws cov crystalline daim ntawv yog me ntsis nkig, yooj yim tawg rau hauv me me raws li cleavage dav hlau nyob rau hauv sab nraud quab yuam. Daim ntawv hmoov yog yooj yim dua dispersed, haum rau sai dissolution thiab cov tshuaj tiv thaiv pib. Thaum sib cuag nrog dej, nws cov txheej txheem kev sib cais yog nrog los ntawm cov nyhuv exothermic tseem ceeb, ua rau muaj kev daws teeb meem meej thiab pob tshab yam tsis muaj teeb meem tshem tawm lossis turbidity. Qhov no tshwm sim yog ze ze rau nws cov dej solubility siab thiab cov qauv kev ncaj ncees.
Thaum lub sij hawm cia thiab kev thauj mus los, phosphorous acid pom zoo zoo li ruaj khov. Txawm li cas los xij, kev cia ntev ntev hauv cov av ntub lossis siab - qhov kub thiab txias ib puag ncig tuaj yeem ua rau me ntsis deliquescence, txo qhov ci ntsa iab, thiab txawm tias clumping. Qhov no qhia tau hais tias yuav tsum tau tswj ib puag ncig ib puag ncig kom tswj tau nws qhov qub tsos thiab physicochemical zog. Rau cov neeg siv khoom lag luam thiab cov chaw sim, kev tshuaj xyuas qhov muag tuaj yeem tshuaj ntsuam cov qauv sai rau kev ua kom pom tseeb lossis muaj kev sib kis nrog cov khoom txawv teb chaws, muab kev pov thawj ua ntej rau kev tshuaj xyuas cov khoom txuas ntxiv thiab cov txheej txheem siv.
Hauv cov ntsiab lus, phosphorous acid yog tus cwj pwm los ntawm nws cov dawb crystalline los yog hmoov, xim ntshiab, thiab zoo li qub. Cov yam ntxwv pom no tsis yog tsuas yog cuam tshuam txog kev ruaj ntseg ntawm nws lub cev tab sis kuj ua lub luag haujlwm tseem ceeb hauv kev txheeb xyuas thiab kev tswj xyuas zoo hauv kev tsim khoom thiab kev tshawb fawb txog kev tshawb fawb.
