01. Hydroxyethyl cellulose
Raws li cov tsis-ionic surfactant, hydroxyethyl cellulose, thicking, zaj duab xis, ua yeeb yaj kiab, tab sis kuj muaj cov khoom siv hauv qab no:
1. HEC yog Soluble hauv dej kub lossis dej txias, thiab tsis yog nag lossis rhaub, yog li nws muaj ntau yam ntawm solubility, thiab tsis-thermal gelation;
2. Piv nrog lees paub methyl cellulose thiab hydroxypropyl cellulose, lub zog impersing ntawm HEC yog qhov phem tshaj, tab sis kev tiv thaiv kev tiv thaiv muaj zog tshaj.

Ceev faj thaum siv:
Txij li thaum lub ntsej muag zoo hydroxyethyl cellulose yog hmoov los yog cellulose khoom, nws yog qhov yooj yim los tuav thiab yaj hauv dej ntev li ntev tau sau tseg.
1. Ua ntej thiab tom qab ntxiv hydroxyethyl cellulose, nws yuav tsum txuas ntxiv kom txog thaum cov tshuaj yog tshab tshab thiab meej.
2. Nws yuav tsum yog sieved rau hauv kev sib xyaw qeeb. Tsis txhob ncaj qha ntxiv rau hydroxyethyl cellulose uas tau tsim rau hauv cov lumps lossis pob rau hauv cov kev sib xyaw ua ke lossis ncaj qha.
3. Cov dej kub thiab lub py tus nqi ntawm cov dej muaj kev sib raug zoo tseem ceeb nrog kev sib txawv ntawm hydroxyethyl cellulose, yog li kev tshwj xeeb yuav tsum them rau nws.
4. Tsis txhob ntxiv qee cov tshuaj alkaline rau cov sib tov ua ntej hydroxyethyl cellulose hmoov yog ua kom sov los ntawm dej. Tsa tus nqi PH tom qab ua kom sov yog pab tau rau kev sib txawv.
HEC siv:
1. Feem ntau siv raws li thickening tus neeg sawv cev, cov tshuaj nplaum, cov khoom siv, pleev tshuaj, kuj tseem siv tau raws li lub stabilizer nyob rau hauv cov zaub mov.
2. Nws yog siv los ua cov neeg sawv cev rau kev lag luam textile, thickening, emulsify, ruaj khov nyob rau hauv electronics thiab teeb pom kev lag luam.
3. Siv raws li thickener thiab filtrate reducer rau dej-raws li drilling kua thiab ua kua, thiab muaj cov txiaj ntsig zoo ntawm cov kua dej. Nws kuj tseem siv tau los ua cov tshuaj tswj cov dej kom ua rau cov roj kom zoo. Nws tuaj yeem hla nrog cov polyvalent hlau ions los ua cov gels.
5. Cov khoom no yog siv los ua cov khoom tsis sib xws rau dej-based gel fracturing kua, polystyrene thiab polyvinyl chloride nyob rau hauv cov roj av ntau lawm. Nws kuj tseem siv tau ua emulsion thickener rau hauv kev lag luam pleev xim, Masas Coagication inhagitor thiab noo noo khaws cov neeg sawv cev hauv kev tsim kho. Glazing thiab tshuaj txhuam hniav nplaum nplaum nplaum rau txoj kev lag luam ceramic. Nws tseem dav siv hauv kev luam ntawv thiab dyeing, textile, papermaking, tshuaj, cov khoom noj, tshuaj tua kab, tshuaj tua kab thiab tua hluav taws.
02.hydroxyPropy Cellulose cellulose
1. Txheej kev lag luam: raws li cov tuab, dispersant thiab stabilizer nyob rau hauv txheej kev lag luam, nws muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic. Raws li cov xim tshem tawm.
2. Ceramic Raug: Siv Dav Ua Binder hauv kev tsim cov khoom lag luam Ceramic.
3. Lwm yam: Cov khoom no tseem dav siv nyob rau hauv tawv, daim ntawv kev lag luam, txiv hmab txiv ntoo thiab zaub kev lag luam thiab lwm yam.
4. Ink Printing: Ua tuab, dispersant, dispersant thiab stabilizer nyob rau hauv Ink kev lag luam, nws muaj kev sib raug zoo hauv dej lossis cov kuab tshuaj organic.
5. Yas: Siv raws li cov neeg sawv cev tso tawm, cov muag muag, roj nplua nyeem, thiab lwm yam.
6. Cov tshuaj polyvinylinal: nws yog siv los ua cov ntawv tsis sib xws hauv kev tsim cov polyvinyl chloride, thiab nws yog lub ntsiab uckiliary Tus neeg saib xyuas rau kev ncua ntawm pvc los ntawm kev ncua qib polymerization.
7. Kev lag luam kev tsim kho: raws li cov dej-tuav tus neeg sawv cev thiab cov so dag zog rau cov cement cug, lub tshuaj khib lav tsis tau. Siv los ua cov binder nyob rau hauv plastering paste, gypsum, putty hmoov lossis lwm yam khoom siv hauv tsev los txhim kho kev ua haujlwm thiab lub sijhawm ua haujlwm ntev. Nws yog siv los ua cov muab tshuaj txhuam rau cov pobzeb ceramic, thiab kho kom zoo nkauj, ua cov tshuaj pleev xim ntxiv, thiab nws kuj tuaj yeem txo cov cement. Cov dej rov qab ntawm hydroxypropyl methylcellose HPMC tuaj yeem tiv thaiv kom tsis txhob tawg vim tias ua kom nrawm nrawm tom qab daim ntawv thov, thiab txhim kho lub zog tom qab ua kom tawv tawv.
8. Tshuaj lag luam: cov khoom siv txheej; Cov ntaub ntawv zaj duab xis; Tus Nqi-Tswj-Cov Khoom Siv Polymer rau kev npaj ua kom tau txais; stabilizers; Cov neeg sawv cev tsis ncua; Ntsiav tshuaj txiag; sib luam tav.
Xwm:
1. Pom: Dawb lossis tawv nqaij dawb.
2. Paus taus loj me; 100 Mesh Pass tus nqi yog ntau dua 98.5%; 80 Mesh Pass tus nqi yog 100%. Lub particle loj ntawm cov ntaub ntawv tshwj xeeb yog 40 ~ 60 mesh.
3. Cov pa roj cua kub: 280-300 ℃
4. Pom meej ntom ntom: 0.25-0.70g / cm (feem ntau nyob ib ncig ntawm 0.5g / cm), tshwj xeeb lub ntiajteb txawj nqus 1.26-1.31.
5. Txhaum Kub Kub: 190-200 ℃
6. Sab nro: 2% tshuaj aque yog 42-56dyn / cm.
7. Solubility: soluble hauv dej thiab qee cov kuab tshuaj, dej, propanol / dej aqueous yog cov nquag ua haujlwm. Siab transparency thiab ruaj khov ua tau zoo. Cov khoom sib txawv ntawm cov khoom muaj ntau qhov chaw kub sib txawv, thiab solubility hloov nrog viscosity. Qhov qis dua viscosity, muaj ntau dua cov solubility. Cov kev sib txawv ntawm HPMC muaj cov khoom sib txawv. Kev sib cais ntawm HPMC hauv dej tsis cuam tshuam los ntawm PH tus nqi.
8. Nrog qhov txo qis ntawm methoxy pab pawg muaj txiaj ntsig, dej solubility txo qis, thiab cov kev ua si ntawm HPMC txo qis.
9. HPMC kuj muaj cov yam ntxwv ntawm thickening muaj peev xwm, cov hmoov tshauv uas tsis muaj tseeb, ua kom muaj kev ruaj khov, dej ua yeeb yam, qhov tsis txaus ntseeg, kev tawm tsam thiab cohesiveness.
