Yuav siv sodium carboxymethyl cellulose li cas thiab contraindications

1. Sib tov sodium carboxymethyl cellulose nrog dej ncaj qha kom ua tau ib daim nplaum thiab muab tso rau ib sab.

Thaum teeb tsa sodium carboxymethyl cellulose paste, ua ntej ntxiv ib qho dej huv rau hauv lub tank batching nrog lub cuab yeej nplawm, thiab nchuav sodium carboxymethyl cellulose qeeb qeeb thiab sib npaug rau hauv lub tank batching, txuas ntxiv nplawm, kom cov sodium carboxymethyl cellulose thiab dej sib xyaw ua ke tag nrho, thiab cov sodium carboxymethyl cellulose tuaj yeem yaj tag nrho. Thaum yaj sodium carboxymethyl cellulose, qhov laj thawj vim li cas nws yuav tsum tau nchuav sib npaug thiab nplawm tas li yog "tiv thaiv kev sib sau ua ke thiab kev sib sau ua ke thaum sodium carboxymethyl cellulose ntsib dej, thiab txo qhov zoo ntawm carboxymethyl cellulose. Kev yaj ntawm sodium", thiab nce tus nqi yaj ntawm sodium carboxymethylcellulose. Lub sijhawm nplawm tsis sib xws nrog lub sijhawm yaj tag nrho ntawm sodium carboxymethyl cellulose. Lawv yog ob lub tswv yim. Feem ntau hais lus, lub sijhawm nplawm luv dua li lub sijhawm xav tau rau kev yaj tag nrho ntawm sodium carboxymethyl cellulose. Lub sijhawm xav tau nyob ntawm qhov xwm txheej tshwj xeeb. Lub hauv paus rau kev txiav txim siab lub sijhawm sib xyaw yog: thaum cov sodium carboxymethyl cellulose tau sib xyaw ua ke hauv dej thiab tsis muaj cov agglomerate loj pom tseeb, qhov kev sib xyaw tuaj yeem nres, thiab cov sodium carboxymethyl cellulose thiab dej raug tso cai sawv ntsug. Nkag mus thiab sib koom ua ke. Lub hauv paus rau kev txiav txim siab lub sijhawm xav tau rau sodium carboxymethylcellulose kom yaj tag nrho yog raws li nram no:

(1) Sodium carboxymethyl cellulose thiab dej tau sib txuas ua ke tag nrho, thiab tsis muaj kev sib cais ntawm cov khoom khov thiab kua ntawm ob qho;

(2) Cov tshuaj sib xyaw ua ke yog nyob rau hauv ib lub xeev sib xws, thiab qhov chaw yog tiaj tus thiab du;

(3) Cov xim ntawm cov tshuaj sib xyaw yog ze li tsis muaj xim thiab pob tshab, thiab tsis muaj cov khoom granular hauv cov tshuaj sib xyaw. Txij lub sijhawm uas cov sodium carboxymethyl cellulose raug muab tso rau hauv lub tank batching thiab sib xyaw nrog dej kom txog thaum cov sodium carboxymethyl cellulose yaj tag, lub sijhawm xav tau yog ntawm 10 thiab 20 teev.

2. Sib tov sodium carboxymethyl cellulose nrog cov khoom siv qhuav xws li suab thaj dawb rau hauv daim ntawv qhuav, thiab tom qab ntawd muab tso rau hauv dej kom yaj.

Thaum lub sijhawm ua haujlwm, ua ntej muab sodium carboxymethyl cellulose thiab cov suab thaj dawb thiab lwm yam khoom siv qhuav rau hauv lub tshuab sib tov hlau tsis xeb raws li qhov sib piv, kaw lub hau sab saum toj ntawm lub tshuab sib tov, thiab khaws cov khoom siv hauv lub tshuab sib tov kom tsis txhob muaj pa. Tom qab ntawd, tig lub tshuab sib tov, sib tov tag nrho cov sodium carboxymethyl cellulose thiab lwm yam khoom siv raw. Tom qab ntawd, maj mam thiab sib npaug cov sodium carboxymethyl cellulose sib tov rau hauv lub tank batching uas muaj dej, thiab txuas ntxiv sib tov, thiab cov haujlwm hauv qab no tuaj yeem ua tiav nrog kev siv thawj txoj kev yaj uas tau hais los saum toj no.

3. Thaum siv sodium carboxymethyl cellulose hauv cov kua lossis cov khoom noj slurry, nws yog qhov zoo tshaj plaws los sib xyaw cov khoom sib xyaw kom tau txais cov ntaub so ntswg zoo dua thiab cov txiaj ntsig ruaj khov.

Lub siab thiab kub siv rau homogenization yuav tsum txiav txim siab raws li cov yam ntxwv ntawm cov khoom siv thiab cov kev xav tau zoo ntawm cov khoom.

4. Tom qab cov sodium carboxymethyl cellulose raug npaj rau hauv cov kua dej, nws yog qhov zoo tshaj plaws los khaws cia rau hauv cov thawv ceramic, iav, yas, ntoo thiab lwm yam thawv. Cov thawv hlau, tshwj xeeb tshaj yog cov thawv hlau, txhuas, thiab tooj liab, tsis haum rau kev khaws cia.

Vim tias yog tias cov kua sodium carboxymethyl cellulose aqueous sib cuag nrog lub thawv hlau ntev, nws yooj yim ua rau puas tsuaj thiab viscosity txo qis. Thaum cov kua sodium carboxymethyl cellulose aqueous sib koom ua ke nrog cov hlau lead, hlau, tin, nyiaj, txhuas, tooj liab thiab qee yam hlau, cov tshuaj tiv thaiv nag yuav tshwm sim, txo qhov ntau thiab zoo ntawm sodium carboxymethyl cellulose hauv cov tshuaj. Yog tias nws tsis tsim nyog rau kev tsim khoom, sim tsis txhob sib tov calcium, magnesium, ntsev thiab lwm yam tshuaj hauv cov tshuaj sodium carboxymethyl cellulose aqueous. Vim tias, thaum cov kua sodium carboxymethyl cellulose aqueous sib koom ua ke nrog calcium, magnesium, ntsev thiab lwm yam tshuaj, viscosity ntawm cov kua sodium carboxymethyl cellulose yuav raug txo qis.

5. Cov kua sodium carboxymethyl cellulose uas tau npaj lawm yuav tsum siv kom tag sai li sai tau.

Yog tias cov kua dej sodium carboxymethyl cellulose khaws cia ntev, nws yuav tsis tsuas yog cuam tshuam rau kev ua haujlwm ntawm cov nplaum thiab kev ruaj khov ntawm sodium carboxymethyl cellulose, tab sis kuj raug tawm tsam los ntawm cov kab mob me me thiab cov kab tsuag, yog li cuam tshuam rau qhov zoo ntawm cov khoom siv raw. Txawm li cas los xij, qee cov thickeners yog dextrins thiab cov hmoov txhuv nplej siab hloov kho uas tsim los ntawm cov hmoov txhuv nplej siab hydrolysis. Lawv tsis muaj tshuaj lom thiab tsis muaj teeb meem, tab sis lawv yooj yim ua rau cov ntshav qab zib nce siab zoo li cov suab thaj dawb, thiab tej zaum yuav ua rau cov ntshav qab zib ntau dua. Qee tus neeg siv khoom cov ntshav qab zib nce siab tom qab haus cov mis nyuj tsis muaj qab zib, uas yuav tshwm sim los ntawm cov thickeners, tsis yog vim muaj cov lactose hauv mis nyuj, vim tias cov lactose ntuj tsis ua rau cov ntshav qab zib nce siab sai. Yog li ntawd, ua ntej yuav cov khoom tsis muaj qab zib, nco ntsoov nyeem cov npe khoom xyaw thiab ceev faj txog qhov cuam tshuam ntawm cov thickeners rau cov ntshav qab zib.
