Cov xab npum ua kua yog ib qho kev siv tshuaj ntxuav kom ntau thiab dav siv tu kom muaj nuj nqis rau nws yooj yim. Txawm li cas los xij, qee kis, cov neeg siv yuav xav tau ib qho tuab ua ke rau kev txhim kho kev ua tau zoo thiab ntawv thov. Hydroxyethylulose (HEC) yog cov neeg sawv cev ua kom nrov siv kom tau viscosity xav tau hauv cov kua xab npum ua haujlwm.
Kawm txog hydroxyethyl cellulose (HEC):
Cov qauv tshuaj thiab cov khoom:
HEC yog dej-soluble polymer muab tau los ntawm cellulose, lub ntuj polymer pom hauv tsob ntoo cell phab ntsa.
Nws cov qauv tshuaj lom neeg suav nrog cov kab cellulose nrog cov pab pawg hydroxyethyl, ua rau cov soluble hauv dej thiab sib haum nrog ntau yam.
Thickening tshuab:
Hec thickens kua los ntawm kev nce viscosity los ntawm cov dej tuav thiab ua yeeb yaj kiab zaj duab xis.
Nws ua cov kab peb-seem hauv dej, tsim cov gel zoo li cov qauv uas ua kom muaj cov kua dej sib xws.
Sib xyaw nrog surfactants:
HEC muaj qhov sib xyaw zoo nrog surfactants feem ntau siv hauv cov kua xab npum ua haujlwm.
Nws qhov ruaj khov nyob hauv lub xub ntiag ntawm cov tshuaj sib txawv ua rau nws zoo tagnrho rau cov khoom siv xab npum thickening.
Yam cuam tshuam rau xab npum thickening:
Daim ntawv qhia Siav tshuaj:
Nws yog qhov tseem ceeb kom nkag siab txog cov khoom xyaw yooj yim ntawm cov xab npum kua. Lub xub ntiag ntawm qee ions, pH, thiab lwm cov feem muaj peev xwm cuam tshuam rau kev ua haujlwm hauv Hec.
Yuav tsum viscosity:
Ib lub hom phiaj tau hais meej yog qhov tseem ceeb los txiav txim siab qhov tsim nyog ntawm Hec siv.
kub:
Kub thaum tsim kev cuam tshuam cuam tshuam rau kev sib cais thiab ua kom ua haujlwm ntawm HEC. Thov kom tau hloov kho raws li kev ua haujlwm kub.
Muab cov zaub mov ua kua
Cov ntaub ntawv thiab khoom siv:
Sau cov khoom xyaw uas tsim nyog nrog rau cov kua xab npum, hec hmoov, dej, thiab lwm yam kev ntxiv.
Nruab nrog nws cov thawv ntim, Stirrer thiab Ph '.
Kev npaj ntawm HEC daws:
Ntsuas qhov yuav tsum tau ntawm HEC hmoov raws li qhov xav tau viscosity.
Maj mam ntxiv HEC rau cov dej sov, nplawm tas li los tiv thaiv clumping.
Tso cai rau qhov sib xyaw kom haum rau hydrate thiab swell.
Muab kev daws teeb meem nrog cov kua xab npum:
Maj mam ntxiv txoj kev daws teeb meem rau cov kua tshuaj pleev tes ua kua thaum kov maj mam muab.
Nco ntsoov muab faib cov yaumy kom zam cov koog thiab tsis sib xws.
Saib saib viscosity thiab kho raws li xav tau.
Ph Haum:
Ntsuas cov ph ntawm qhov sib tov thiab kho yog tias tsim nyog siv citric acid lossis sodium hydroxide.
Saib xyuas cov kab ntawv zoo yog qhov tseem ceeb rau kev ruaj ntseg ntawm cov qauv.
Kuaj thiab ua kom zoo:
Viscire kev ntsuam xyuas tau ua rau ntau theem los ua kom zoo ntawm HEC.
Kho cov lus qhia raws li kev sim cov txiaj ntsig kom txog thaum muaj kev xav tau ua tiav.
Kev Ruaj Ntseg thiab Kev Txiav Txim Siab:
Anti-Corrosion System:
Muab cov tshuaj tiv thaiv kom haum kom tiv thaiv microbial paug thiab txuas lub txee lub neej ntawm tuab xab npum.
Pob:
Xaiv cov ntaub ntawv ntim uas tsim nyog uas tsim nyog yuav tsis siv nrog xab npum lossis daws teeb meem hec.
Kev Cia Cai Cia:
Khaws cov kua xab npum ua kua kom qhuav hauv qhov chaw txias, qhuav kom deb ntawm tshav ntuj ncaj qha los tswj nws cov ruaj khov thiab zoo dua lub sijhawm ntev.
Hydroxyethylcellose yog cov tuab muaj txiaj ntsig zoo uas muab ib qho kev daws teeb meem rau kev ua tiav xav tau viscosity hauv cov xab npum kua ua kua. Los ntawm kev nkag siab tias nws cov khoom, yam cuam tshuam rau cov txheej txheem tuab, thiab cov txheej txheem-ua haujlwm tuaj yeem tsim cov xab npum ua kua zoo thiab ua tau zoo. Kev sim, kev soj ntsuam thiab kev ua kom zoo dua yog qhov tseem ceeb ntawm cov txheej txheem, kom ntseeg tau tias cov khoom kawg tau raws li kev ua haujlwm zoo thiab kev ua kom zoo nkauj. Los ntawm kev txiav txim siab cov khoom xyaw thiab cov kua tshuaj ntxuav tes tuaj yeem muab cov neeg siv khoom nrog cov khoom lag luam zoo thiab zoo nkauj.
