HEC RAU COV XIM

HEC yog luv rau hydroxyethyl cellulose. Hydroxyethyl celluloseTus paYog xim dawb lossis daj ntseg, tsis muaj tshuaj lom, hnoos qeev lossis powdery cov khoom uas npaj tau los ntawm etherine cellulose thiab ethylene oxide (lossis chloroethanol). Nws yog cov tsis-ionic soluble cellulose ether. Raws li tsis yog-ionic surfactant, ntxiv rau cov tuab dua, raug tshem tawm, ua yeeb yaj kiab, ua yeeb yaj kiab, dej rov qab thiab kev tiv thaiv.

Tshuaj Nta:

1, HEC tuaj yeem yaj nyob rau hauv dej kub lossis dej txias lossis npau npau tsis nag thiab viscosity proderties, thiab tsis-thermal gel;

2, nws cov tsis yog-ionic tuaj yeem ua rau muaj lwm yam dej-soluble polymers, solet, solet, yog ib qho zoo tshaj plaws colloidal muaj siab ntawm electrolyte tov;

3, Lub peev xwm kav dej ua haujlwm yog ob zaug dua methyl cellulose, nrog zoo ntws kho tau,

4. HEC muaj lub peev xwm phem tshaj plaws piv nrog lees paub methyl cellulose thiab hydroxypropyl kev tiv thaiv methylropy, tab sis muaj zog cellOn tiv thaiv muaj peev xwm.

Yog li ntawd, hydroxyethyl cellulose yog dav siv nyob rau hauv petroleum kev siv tshuaj, cov tshuaj, kev tsim kho thiab cov tshuaj tiv thaiv polymerizer thiab lwm thaj teb.

Cov khoom tseem ceeb ntawmTus paRau cov xim pleev xim

1.Cov Khoom Siv Thickening

Hydroxyethyl cellulose (HEC) yog qhov tuab zoo tshaj plaws rau txheej txheej thiab tshuaj pleev ib ce. Hauv kev siv cov ntaub ntawv thov, kev sib xyaw ua ke nrog kev ncua kev kawm, kev nyab xeeb, dispersity thiab dej khaws cia yuav ua tau cov txiaj ntsig zoo tshaj plaws.

1. pseudopastic

Pseudoplastic yog cov cuab yeej uas viscosity ntawm kev daws teeb meem tsawg dua nrog kev nce ntawm kev ua kom nrawm. HEC muaj cov xim looj tes yooj yim yog yooj yim thov nrog txhuam lossis cov menyuam thiab tuaj yeem nce qhov du kom zoo nkauj ntawm cov npoo av, uas tuaj yeem nce ntxiv ua haujlwm; Hec-muaj cov tshuaj zawv plaub hau yog kua thiab nplaum, yooj yim diluted thiab yooj yim dispersed.

1. Cov ntsev ua haujlwm

HEC yog qhov ruaj khov nyob rau hauv cov kua muaj ntsev ua kua ntau thiab tsis decompose rau hauv ionic lub xeev. Siv nyob rau hauv electroplating, tuaj yeem ua rau plating nto ua tiav, ntau kaj. Ntau tus neeg sau ntawv yog daim ntawv thov ntawm borate, silicate thiab carbonate looj xim, tseem muaj cov viscosity heev.

4.Ib tug membranous

Daim iav tsim cov khoom ntawm HEC tuaj yeem siv rau ntau qhov kev lag luam. Hauv kev ua haujlwm papermaking, coated nrog HEC glazing tus neeg sawv cev, tuaj yeem tiv thaiv cov roj av roj, thiab tuaj yeem siv los npaj lwm yam ntawm papermaking tov; HEC tau nce ntxiv txoj kev elasticity ntawm cov fibers thaum lub sij hawm weaving txheej txheem thiab li no txo ​​cov tshuab puas rau lawv. HEC Ua raws li zaj yeeb yaj kiab ib ntus thaum sizing thiab zas ntawm cov ntaub thiab tuaj yeem ntxuav tawm ntawm cov ntaub nrog dej thaum nws tiv thaiv tsis tau.

1. Dej ceev

HEC pab kom cov dej noo ntawm cov kab ke hauv lub xeev zoo tshaj plaws. Vim tias ib qho kev daws teeb meem me me tuaj yeem ua tiav cov txiaj ntsig retentive zoo dua, kom lub kaw lus txo qhov kev thov dej hauv kev npaj. Yog tsis muaj dej rov qab thiab cov nplaum, cemention, thiab cov nplaum, thiab av nplaum yuav tseem yuav txo cov xim av.

Daim ntawv thov txoj kev ntawm hydroxyethyl cellulose Tus paHauv cov xim pleev xim

1. Ntxiv rau qhov ncaj qha thaum sib tsoo xim: hom no yog qhov yooj yim tshaj plaws, thiab lub sijhawm siv yog luv. Cov kauj ruam kom ntxaws yog raws li hauv qab no:

(1) Ntxiv cov dej uas tsim nyog kom tsim nyog rau hauv VAT ntawm cov neeg ua haujlwm siab (feem ntau, ethylene glycol, ntub dej tus neeg sawv cev thiab ua yeeb yaj duab sib sau tus neeg sawv cev yog ntxiv rau lub sijhawm no)

(2) Pib stirring ntawm qhov nrawm nrawm thiab maj mam ntxiv hydroxyethyl cellulose

(3) Txuas ntxiv mus kom txog thaum txhua qhov me me yog tsau

(4) Ntxiv me me mildew inhibitor, Ph Regulator, thiab lwm yam

(5) do kom txog thaum txhua hydroxyethyl cellulose yog tag nrho cov kev daws teeb meem (lub viscosity ntawm kev ntxiv lwm cov hauv cov mis, thiab zom kom txog thaum nws pleev xim.

2 Nruab nrog niam ua kua rau tos: Cov qauv no tau nruab nrog cov xim zoo dua, thiab tom qab ntawd ntxiv rau cov khoom tiav, tab sis yuav tsum muaj kev cia khoom tsim nyog. Cov kauj ruam thiab cov hau kev zoo ib yam li cov kauj ruam (1) - (tsuas yog qee tus neeg mob siab kom muaj lub zog ua kom muaj zog los ua kom cov hydroxyethyl fibers ensy dispersed hauv kev daws tau txaus. Txuas ntxiv nplawm kom txog thaum nws dissolves rau hauv cov tshuaj tuab. Nco ntsoov tias tus neeg inhibitor yuav tsum tau ntxiv rau niam cawv niam hmo kom sai li sai tau.

3. Porridge nyiam phenology: Vim tias organic cov kuab tshuaj rau hydroxyethyl cellulose, cov organic cov kuab tshuaj tuaj yeem nruab nrog porridge. Feem ntau siv cov ethylene glycolent cov neeg sawv cev, thiab ua yeeb yaj kiab tsis zoo nrog cov kua dej tsis zoo nrog cov kua txiv kab ntxwv hauv porridge.

Gruel - zoo li hydroxyethyl cellulose tuaj yeem txuas ncaj qha ntxiv rau cov xim. Hydroxyethyl cellulose tau muab noo nyob hauv daim ntawv porridge daim ntawv. Tom qab ntxiv lacquer, yaj tam sim ntawd thiab muaj cov nyhuv tuab. Tom qab ntxiv, txuas ntxiv mus do kom txog thaum hydroxyethyl cellulose kom yaj thiab niaj hnub. Ib txwm porridge yog ua los ntawm kev sib tov rau feem rau feem ntawm organic kuab tshuaj lossis dej khov nrog ib feem ntawm hydroxyethyl cellulose. Tom qab txog 5-30 feeb, lub hydroxyethyl cellulose hydrolyzes thiab pom tseeb sawv. Nyob rau lub caij ntuj sov, cov av noo ntawm cov dej yog qhov siab dhau lawm yuav siv rau porridge.

4.Cov teeb meem xav tau kev mloog thaum equipping hydroxyethyl cellulose niam cawv

Txij li hydroxyethyl cellulose yog kho cov hmoov av granular, nws yog qhov yooj yim los tuav thiab yaj hauv dej nrog cov kev ceev faj hauv qab no.

Pom

4.1 ua ntej thiab tom qab ntxiv hydroxyethyl cellulose, yuav tsum tau ua kom tiav kom mus kom txog thaum cov kev daws teeb meem tau meej thiab meej.

4.2. Sab cib lub hydroxyethyl cellulose mus rau hauv lub tank sib xyaw. Tsis txhob ntxiv nws mus rau hauv lub tank sib xyaw hauv lub thawv loj hauv cov khoom loj lossis ncaj qha rau hauv cov loj lossis kheej kheej hydroxyethyl cellulose.

4.3 Dej kub thiab pH cov dej muaj piv rau kev sib piv nrog kev sib cais ntawm hydroxyethyl cellulose, yog li tshwj xeeb saib yuav tsum tau them rau nws.

4.4Tsis txhob ntxiv qee qhov yooj yim yeeb tshuaj rau cov sib tov ua ntej cov hmoov hydroxyethyl cellulose hmoov yog soaked nrog dej. Tsa phua tom qab soaking pab yaj.

4.5 kom deb li deb tau, kev sib ntxiv ntxov, ntawm cov neeg ua kom tus inhibitor.

4.6 Thaum siv siab viscosity hydrotyl cellulose, lub concentration ntawm niam cawv yuav tsum tsis txhob siab dua 2.5-3% (los ntawm qhov hnyav), txwv tsis pub tus niam cawv yog qhov nyuaj ua haujlwm.

Yam cuam tshuam rau cov viscosity ntawm looj xim

1 Cov pa npuas ntau dua hauv cov xim, cov viscosity ntau dua.

2 Puas yog tus nqi ntawm cov Activator thiab dej hauv cov xim mis xim sib xws?

3 Hauv synthesis ntawm looj, residual catalyst oxide cov ntsiab lus ntawm tus nqi.

4. Qhov ntau npaum ntawm lwm cov khoom siv cov ntoo hauv cov xim pleev xim thiab cov ntau yam piv nrogTus pahydroxyethyl cellulose.)

5 Nyob rau hauv cov txheej txheem ntawm kev pleev xim, qhov kev txiav txim ntawm cov kauj ruam ntxiv cov thickener yog qhov tsim nyog.

6 Vim tias kev ntxhov siab ntau dhau thiab cov av noo ntau thaum lub sijhawm ua tiav.

7 Microbial yis ntawm tuab.
