Sodium daim ntawv:
Cov sodium tsim feem ntau yog los ntawm daim ntawv ntawm cov hmoov dawb hygroscopic.
Nws yog soluble hauv dej tab sis muaj kev txwv solubility hauv qee cov kuab organic.
Vim nws cov ionic xwm, cov ntais ntawv no muaj qhov sib piv siab dua piv rau cov tshuaj acid.
3. Acc acidic lossis alkaline:
Formic acid:
Formic acid yog cov kua qaub tsis muaj zog uas tuaj yeem pub cov protons (h +) hauv kev siv tshuaj lom neeg.
Sodium daim ntawv:
Sodium tsim yog ntsev los ntawm formic acid; Nws tsis yog acidic. Nyob rau hauv aqueous daws, nws decooses rau sodium ions (na +) thiab tsim ions (hiscoo-).
4. Lub Hom Phiaj:
Formic acid:
Nws yog feem ntau siv nyob rau hauv kev tsim cov tawv, textiles thiab dyes.
Formic acid yog ib qho tseem ceeb ntawm kev ua cov tsiaj hides thiab tawv hauv kev lag luam tawv.
Nws yog siv los ua tus neeg sawv cev txo tus neeg sawv cev thiab khaws cia hauv qee qhov kev lag luam.
Hauv kev ua liaj ua teb, nws tau siv ua cov pub noj ntxiv rau inhibit txoj kev loj hlob ntawm qee cov kab mob thiab fungi.
Sodium daim ntawv:
Kev tsim cov sodium yog siv los ua tus neeg sawv cev ntawm cov icing rau txoj kev thiab kev khiav.
Siv los ua tus neeg sawv cev rau luam tawm thiab zas kev lag luam.
Cov compound no yog siv rau hauv cov av nkos las hauv cov roj thiab roj kev lag luam.
Sodium tsim yog siv los ua tus neeg sawv cev buffering hauv qee cov txheej txheem muaj.
5. Ntau Lawm:
Formic acid:
Formic acid yog tsim los ntawm catalytic hydrogenation ntawm carbon dioxide lossis cov tshuaj tiv thaiv ntawm methanol nrog carbon monoxide.
Muaj cov txheej txheem koom nrog kev siv cov catalysts thiab kev kub siab thiab kev ntsuas.
Sodium daim ntawv:
Cov sodium tsim yog feem ntau tsim los ntawm nruab nrab formic acid nrog sodium hydroxide.
Qhov txiaj ntsig sodium tsim muaj peev xwm raug cais tawm los ntawm crystallization lossis tau hauv cov kua daim ntawv.
6. Kev nyab xeeb ceev faj:
Formic acid:
Formic acid yog corrosive thiab tuaj yeem ua rau kub nyhiab rau ntawm daim tawv nqaij.
Kev nqus tau ntawm nws cov vapors yuav ua rau kev thab plaub rau lub tshuab ua pa.
Sodium daim ntawv:
Txawm hais tias sodium tsim yog feem ntau suav hais tias tsis tshua muaj kev puas tsuaj ntau dua li formic acid, tsim nyog tuav thiab khaws cia tsis tau ua.
Cov lus qhia kev nyab xeeb yuav tsum tau ua raws thaum siv cov sodium tsim kom tsis txhob muaj kev pheej hmoo muaj kev noj qab haus huv.
7. Ib puag ncig cuam tshuam:
Formic acid:
Formic acid tuaj yeem bookodegrade nyob rau hauv qee yam kev mob.
Nws cov kev cuam tshuam rau ib puag ncig raug cuam tshuam los ntawm cov lus xws li xws li lub siab thiab raug lub sijhawm.
Sodium daim ntawv:
Cov sodium tsim yog feem ntau suav tias yog ib puag ncig phooj ywg thiab muaj qhov cuam tshuam qis dua li qee qhov tsis muaj lwm yam de-icers.
8. Nqi thiab muaj:
Formic acid:
Tus nqi ntawm formic acid tuaj yeem sib txawv raws li cov txheej txheem ntau lawm thiab kev ua kom huv.
Nws tuaj yeem muas tau los ntawm ntau tus neeg xa khoom.
Sodium daim ntawv:
Sodium tsim yog luv luv thiab nws cov khoom tau cuam tshuam los ntawm kev thov los ntawm kev lag luam sib txawv.
Nws tau npaj los ntawm nruab nrab formicwork acid thiab sodium hydroxide.
Formic acid thiab sodium tsim yog cov sib txawv nrog cov khoom sib txawv thiab cov ntawv thov. Formic acid yog cov kua qaub tsis muaj zog nyob rau hauv ntau cov ntawv thov, thaum sodium ntsev, yog siv nyob rau hauv cov chaw xws li de-icing, textiles thiab roj thiab roj kev lag luam. Nkag siab txog lawv cov peev xwm tseem ceeb rau kev siv kev nyab xeeb thiab siv tau zoo hauv ntau thaj teb.
