Nyob hauv lub ntiaj teb niaj hnub no, kev lag luam khoom noj siv ntau yam khoom siv hauv kev tsim cov khoom noj khoom haus: dyes, flavors, tsw enhancers, stabilizers thiab lwm yam. Ib qho ntawm lawv yog cov khoom noj ntxiv e238, uas tau txwv hauv ntau lub tebchaws nyob sab Europe vim nws qhov tsis zoo rau tib neeg lub cev. Cov tshuaj yog siv raws li ib tug preservative, nws yog siv los tiv thaiv kev loj hlob ntawm fungi thiab pathogenic microbes. Hauv lwm txoj kev, cov tshuaj ntxiv no hu ua calcium formate.
Kev piav qhia ntawm cov khoom
Calcium formate (Ca(HCOO)2) yog ntsev ntawm formic acid. Nws muaj cov tsos ntawm cov hmoov dawb crystalline nrog ib qho tsw me ntsis.
Calcium formate (E238) dissolves zoo hauv dej, muaj qhov ntom ntawm 1.91 g / cm3, decomposes ntawm 300 degrees Celsius.
yam ntxwv
Calcium formate yog siv ntau qhov chaw, suav nrog kev lag luam khoom noj. Nws yog ib tug preservative, raws li nws yuav pab kom ncua lub txee lub neej ntawm cov khoom, txwv kev loj hlob thiabkev loj hlob ntawm cov kab mob thiab fungi uas ua rau lwj. Tsis tas li, cov khoom muaj lub luag haujlwm rau kev ua kom tsis muaj menyuam, yog ib feem ntawm qee cov nroj tsuag thiab cov kua roj ntsha ntawm cov kab mob nyob.
siv thaj chaw
Nyob rau hauv Russia, calcium formate yog siv nyob rau hauv kev lag luam khoom noj khoom haus raws li preservative thiab ntsev hloov nyob rau hauv zus tau tej cov dej qab zib, raws li zoo raws li nyob rau hauv tag nrho cov khoom noj khoom haus. Thaum fermenting zaub, cov khoom siv kuj tseem siv tau, vim tias nws muaj peev xwm cog cov ntaub so ntswg, kom cov neeg siv khoom tau txais cov khoom noj hauv kaus poom. Cov tshuaj no muaj ib tug feature, nws nthuav tawm cov yam ntxwv antibacterial nkaus xwb nyob rau hauv ib tug acidic ib puag ncig.
Qhov tso cai txhua hnub ntawm cov tshuaj tsis pub ntau tshaj peb grams ib kilogram ntawm tib neeg lub cev qhov hnyav. Hauv kev tsim cov dej qab zib, cov tshuaj ntxiv yog siv tsis pub ntau tshaj 210 milliliters ib liter ntawm kua.
Thaum ntxov, cov khoom noj khoom haus no tau siv rau hauv cov chaw tsim khoom hauv kaus poom thaum sau ntses. Niaj hnub no, nws tau xyaum tsis siv nyob rau hauv cheeb tsam no, txij li thaum lub additive tau hloov nrog tsawg txaus ntshai preservatives.
Calcium formate yog siv rau hauv cosmetology ua ib yam khoom uas tiv thaiv kev lwj ntawm cov khoom kom zoo nkauj (tsis ntau tshaj 0.5%), hauv kev tsim kho kom tawv nqaij. E238 kuj tseem siv rau dyeing fabrics, tanning tawv, luam ntawv xim xim.
Kev cuam tshuam rau lub cev, kev nyab xeeb xav tau
Calcium formate yog txwv tsis pub noj zaub mov hauv ntau lub tebchawsadditive, raws li nws muaj feem cuam tshuam rau tag nrho cov kab ke ntawm tib neeg lub cev (qhov thib peb ntawm kev txaus ntshai). Yog tias kev siv cov tshuaj ntxiv hauv kev lag luam khoom noj tau ua raws li txhua tus qauv, ces nws yuav tsis ua rau muaj kev phom sij sai. Tab sis cov khoom muaj peev xwm mus sau nyob rau hauv lub cev, nws concentration maj mam nce. Thaum lub sij hawm, ib tug neeg tsim ib qho kev tsis haum rau cov additive, irritation ntawm mucous epithelium thiab ua pa ib ntsuj av tau, thiab ib tug pob liab liab tshwm sim ntawm daim tawv nqaij. Yog li, nws tau pom tias cov tshuaj tua kab mob tsis coj cov txiaj ntsig rau tib neeg lub cev.
Nws ua rau muaj kev phom sij rau cov neeg uas tau ntsib nrog cov tshuaj no. Yog li ntawd, thaum ua hauj lwm nrog cov additive, nws yog tsim nyog los soj ntsuam kev ruaj ntseg ntsuas. Nws yog ib qho tsim nyog yuav tsum siv cov cuab yeej tiv thaiv tus kheej (lub tshuab ua pa, lub tshuab nqus tsev, cov hnab looj tes roj hmab, thiab lwm yam). Thaum muaj xwm txheej ceev, yuav tsum siv lub npog ntsej muag roj.
Technical calcium formate yog non-flammable thiab non-explosive. Nws yuav tsum tau khaws cia nyob rau hauv tej yam kev mob. Tsis txhob haus luam yeeb lossis siv cov nplaim taws qhib qhov twg nws siv, xws li hauv lub cannery.
Ntim thiab khaws cia
Cov khoom ntim rau hauv hnab 25 kg. Kev thauj mus los yuav tsum tau ua raws li tag nrho cov kev cai tsim rau cov khoom zoo li no. Khaws cov khoom ntawm pallets hauv qhuav, kaw cov chav uas muaj qhov cua zoo. Lub txee lub neej yog ib xyoos txij li hnub tsim cov khoom ntxiv. Cov khoom muaj peev xwm nqus tau dej zoo, yog li nws yuav tsum tau muab khaws cia rau hauv ntim ntim.
Cov khoom noj khoom haus no yog tsim los ntawmKev lag luam chemical.
Zoo kawg
Calcium formate yog cov khoom noj khoom haus ntxiv, khaws cia thiab ruaj khov, uas yog lub luag haujlwm rau kev nyab xeeb ntawm cov khoom noj khoom haus, nres kev loj hlob thiab kev loj hlob ntawm cov kab mob microbes thiab fungi. Tsis tas li ntawd, cov tshuaj no yog siv los ua kom tsis muaj menyuam txhawm rau txhawm rau txhawm rau kom loj hlob ntawm cov cawv, nrog rau cov tshuaj tua kab mob.
Cov tshuaj yog hydrophilic, yog li nws feem ntau yog siv los ua ib qho accelerator rau hardening pob zeb thiab lwm yam vaj tsev sib tov, nrog rau cov tshuaj tiv thaiv Frost additive hauv pob zeb. Vim muaj cov calcium formate hauv pob zeb ntawm 2-4%, nws lub zog compressive nce.
Hnub no cov zaub mov no tau txwv tsis pub siv ntau lub tebchaws. Qhov no yog vim lub fact tias nws tsis zoo rau tib neeg lub cev, maj accumulating nyob rau hauv nws. Cov additive xav tau qee yam kev cia thiab kev thauj mus los. Thaum ua haujlwm nrog nws, koj yuav tsum siv cov cuab yeej tiv thaiv tus kheej.
