Sodium daim

Sodium daimyog cov hmoov dawb paug hmoov lossis crystalline, nrog me ntsis formic acid tsw. Soluble hauv dej thiab glycerin, me ntsis soluble hauv ethanol, insoluble hauv ether. Lom. Yuav siv tau hauv kev tsim cov formic acid, oxalic acid, kev tuav pov hwm thiab tawv tanneryource acid, siv hauv catalysts.

Khoom:Sodium daim ntawv yog dawb crystalline hmoov, me ntsis formic acid tsw, soluble hauv ethanol, delix taw tes 253 ℃, delix hauv huab cua, tshuaj lom neeg ruaj khov.

Cov ntawv thov MAIN:

Siv hauv kev lag luam tawv, lub ntsiab siv yog raws li hauv qab no:

(1) tsuas yog siv nyob rau hauv kev tsim cov formic acid, oxalic acid thiab tseem siv nyob rau hauv kev tsim khoom ntawm Diaethylformamide, thiab lwm yam siv hauv kev lag luam, luam ntawv thiab zas kev lag luam. ;

(2) reagents, tshuaj tua kab mob thiab mordant rau kev txiav txim siab ntawm phosphorus thiab arsenic;

(3) siv los ua cov tshuaj tiv thaiv.Ro alkyd resin txheej, yas txias, muaj zog;

(4) siv los ua cov khoom tawg, acid-resistant cov ntaub ntawv, aviamiation roj, adhesive additives.

Sodium daim ntawv thiabCAlcium tsim:

Sodium tsim thiab calcium tsim yog ob lub tshuab hlau ib txwm muaj ntawm kev tsim. Cov sodium tsim yog tseem hu ua sodium daim. Muaj ob hom molecular ntawm sodium tsim cov tebchaw hauv xwm:

① Anhydrous sodium tsim yog cov hmoov dawb crystalline, Hygroscopic, tshuaj lom. Tus txheeb ze ceev yog 1.92 (20 ℃) ​​thiab lub poelting point yog 253 ℃. Soluble hauv dej, me ntsis soluble hauv ethanol, insoluble hauv ether.

② Sodium dihydrate yog xim tsis muaj xim crystal. Me ntsis formic acid tsw, lom. Soluble hauv dej thiab glycerin, me ntsis soluble hauv ethanol. Ntawm qhov kub siab, nws tawg rau hauv hydrogen thiab sodium oxalate, thiab thaum kawg mus rau sodium carbonate. Nws yog tsim los ntawm kev sib cuam tshuam ntawm formic acid nrog sodium hydroxide.

Lub ntsiab siv ntawm sodium tsim muaj raws li nram no:

Cov sodium tsim tuaj yeem siv ua tshuaj ntsuam xyuas cov tshuaj lom neeg, siv rau kev txiav txim siab, mordant, thiab lwm yam los hloov cov formic acid los txhim kho kev ua haujlwm ntawm limestone FGD system.

Kev npaj txoj kev ntawm sodium daim ntawv:Sodium Bicarbonate yog siv nyob rau hauv chav kuaj kom hnov ​​mob nrog formic acid mus rau cov tshuaj alkaline, tshem tawm thiab crystallize kom tau txais cov ntses nyoos.

Calcium tsim yog ntws dawb crystalline hmoov nrog anti-mould, tiv thaiv corrosion thiab tshuaj tua kab mob. Nws yog ib organic acid pub ntxiv. Cov ntsiab lus ntawm 99%, 69% formic acid, 31% calcium, cov ntsiab lus dej qis. Cov khoom no muaj cov ntsiab lus siab thiab tsis yooj yim kom raug rhuav tshem hauv cov khoom siv granular. Ntxiv 0.9% ~ 1.5% hauv kev pub. Cov khoom no cais cov acid hauv lub plab, tswj hwm lub plab, thiab tiv thaiv kev cuam tshuam thiab tiv thaiv kev mob plab zom mov nrog tus kab mob raws plab. Qeb formic acid tuaj yeem ua kom ua haujlwm ntawm pepsinogen thiab txhim kho kev nqus cov khoom xyaw nquag hauv kev pub. Chelate nrog cov zaub mov nyob rau hauv pub los txhawb kev zom zaub mov thiab nqus cov zaub mov; Nws kuj tseem siv tau ua cov tshuaj calcium. Nws tuaj yeem tiv thaiv raws plab thiab txhim kho kev muaj sia nyob tus piglets. Txhawb nqa pub hloov dua siab tshiab thiab nce txhua hnub.

Ntim, cia thiab tsheb thauj mus los:Ntim hauv cov hlau nruas nrog yas zaj duab xis, khaws cia rau hauv qhov chaw txias, kom deb ntawm cov cua sov, kua qaub, huab cua sov.

Hauv kev xaus, sodium tsim yog qhov tseem ceeb ua ke uas ua lub luag haujlwm tseem ceeb hauv kev lag luam ntau yam. Nws yog siv nyob rau hauv kev tsim cov tshuaj tsim nyog, suav nrog formic acid, oxalic acid, thiab kuj yog siv hauv kev lag luam tawv. Nws cov kev sib tham eco, durability, thiab versatility ua rau nws muaj qhov kev xaiv zoo tshaj plaws hauv ob peb daim ntawv thov. Xws li, nws yog qhov sib txuas tsim nyog tshawb nrhiav los ntawm kev lag luam uas muaj peev xwm tau txiaj ntsig ntawm nws cov khoom.
