Yuav ua li cas txiav txim qhov zoo ntawm cellulose los ntawm cov hmoov tshauv ntawm hydroxypropyl methylcellulose tom qab combustion

Ua ntej ntawm tag nrho cov, peb yuav tsum to taub dab tsi yog tshauv:

01. Cov ntsiab lus tshauv tseem hu ua hluav taws kub, uas tuaj yeem nkag siab yooj yim li impurities hauv cov khoom.Nws yuav raug tsim tawm thaum lub sijhawm tsim khoom.Tom qab cov khoom tawm los ntawm etherification reactor, nws yuav nkag mus rau hauv lub tank neutralization.Nyob rau hauv lub tank neutralization, tus nqi pH yog thawj zaug hloov mus rau nruab nrab, thiab tom qab ntawd dej kub ntxiv rau kev ntxuav.Cov dej kub ntau ntxiv, Ntxuav, ntau lub sij hawm ntawm kev ntxuav, cov hmoov tshauv qis dua, thiab vice versa.

02. Qhov luaj li cas ntawm cov tshauv tseem pom nyob rau hauv purity ntawm cellulose, qhov siab dua qhov purity, qhov tsawg dua cov tshauv tom qab hlawv!

Tom ntej no, cia peb txheeb xyuas cov ntaub ntawv peb tau txais los ntawm cov txheej txheem kub hnyiab ntawm hydroxypropyl methylcellulose.

Ua ntej: Cov hmoov tshauv tsawg dua, qhov zoo dua

Determinants ntawm tus nqi ntawm cov tshauv residue:

(1) Zoo ntawm cov khoom siv cellulose zoo (cov paj rwb zoo): Feem ntau, qhov zoo ntawm cov paj rwb zoo dua qub, cov khoom siv cellulose zoo dua, cov hmoov tshauv thiab dej tuav tau zoo dua.

(2) Tus naj npawb ntawm lub sij hawm ntxuav: yuav muaj tej plua plav thiab impurities nyob rau hauv cov ntaub ntawv raw, ntau lub sij hawm ntawm ntxuav, cov hmoov tshauv me me ntawm cov khoom tiav tom qab hlawv.

(3) Ntxiv cov khoom me me rau cov khoom tiav yuav ua rau cov hmoov tshauv ntau tom qab hlawv

(4) Kev ua tsis tau zoo thaum lub sijhawm tsim khoom yuav cuam tshuam rau cov hmoov tshauv ntawm cellulose

(5) Txhawm rau kom tsis meej pem txhua tus neeg lub zeem muag, qee cov tuam txhab yuav ntxiv cov hluav taws xob nrawm rau nws, thiab yuav luag tsis muaj tshauv tom qab hlawv.Nws hlawv tag nrho, tab sis cov xim tom qab hlawv tseem txawv heev ntawm cov hmoov ntshiab.

Thib ob: qhov ntev ntawm lub sijhawm hlawv:

Cellulose nrog cov dej tuav tau zoo yuav hlawv rau lub sijhawm ntev, thiab rov qab rau cov dej khaws cia tsawg.
