Kumanga kalasi MHEC

Kumanga kalasi MHEC Methyl HydroxyethylCellulosendi ufa woyera wopanda fungo, wosakoma, wopanda poizoni womwe ukhoza kusungunuka m'madzi ozizira kuti upangitse njira yowonekera yowonekera. Lili ndi makhalidwe a thickening, kugwirizana, kubalalitsidwa, emulsification, filimu mapangidwe, kuyimitsidwa, adsorption, gelation, pamwamba ntchito, kusunga chinyezi ndi colloid zoteteza. Popeza njira yamadzimadzi imakhala ndi ntchito yogwira pamwamba, imatha kugwiritsidwa ntchito ngati colloidal protective agent, emulsifier ndi dispersant. Kumanga kalasi ya MHEC methyl Hydroxyethylcellulose yankho lamadzimadzi lili ndi hydrophilicity yabwino ndipo ndi njira yabwino yosungira madzi. Hydroxyethyl methyl cellulose ili ndi magulu a hydroxyethyl, kotero imakhala ndi mphamvu yabwino yotsutsa nkhungu, kukhazikika kwa viscosity ndi anti-mildew panthawi yosungirako nthawi yayitali.

Thupi ndi mankhwala katundu:

Maonekedwe: MHEC ndi woyera kapena pafupifupi woyera fibrous kapena granular ufa; wopanda fungo.

Kusungunuka: MHEC ikhoza kusungunuka m'madzi ozizira ndi madzi otentha, chitsanzo cha L chikhoza kusungunuka m'madzi ozizira, MHEC sichisungunuka m'madzi ambiri osungunulira. Pambuyo pa chithandizo chapamwamba, MHEC imabalalitsa m'madzi ozizira popanda agglomeration, ndipo imasungunuka pang'onopang'ono, koma imatha kusungunuka mwamsanga mwa kusintha mtengo wake wa PH wa 8 ~ 10.

Kukhazikika kwa PH: Kukhuthala kumasintha pang'ono mkati mwa 2 ~ 12, ndipo kukhuthala kumachepera kuposa izi.

Granularity: 40 mesh pass rate ≥99% 80 mesh pass rate 100%.

Kachulukidwe wowoneka: 0.30-0.60g/cm3.

Kugwiritsa ntchito 

Kumanga kalasi ya MHEC methyl Hydroxyethyl cellulose ingagwiritsidwe ntchito ngati colloid yoteteza, emulsifier ndi dispersant chifukwa cha ntchito yake yogwira ntchito mu njira yake yamadzimadzi. Zitsanzo zamagwiritsidwe ake ndi izi:

1. Zotsatira za methylhydroxyethylcellulose pa ntchito ya simenti.Kumanga kalasi ya MHEC methylHydroxyethylcellulose ndi ufa wonyezimira wopanda fungo, wopanda poizoni, wopanda poizoni womwe ukhoza kusungunuka m'madzi ozizira kuti ukhale wowonekera bwino wa viscous. Lili ndi makhalidwe a thickening, kugwirizana, kubalalitsidwa, emulsification, filimu mapangidwe, kuyimitsidwa, adsorption, gelation, pamwamba ntchito, kusunga chinyezi ndi colloid zoteteza. Popeza njira yamadzimadzi imakhala ndi ntchito yogwira ntchito pamwamba, ingagwiritsidwe ntchito ngati colloid yoteteza, emulsifier ndi dispersant.Building grade MHEC methyl Hydroxyethyl cellulose aqueous solution imakhala ndi hydrophilicity yabwino ndipo imakhala yothandiza kusunga madzi.
2. Konzani utoto wotsitsimula ndi kusinthasintha kwakukulu, komwe kumapangidwa ndi zigawo zotsatirazi ndi kulemera kwa zipangizo: 150-200g ya madzi a deionized; 60-70g wa emulsion woyera akiliriki; 550-650g wa calcium wolemera; 70-90 g wa tchizi; 30-40g ya methyl cellulose amadzimadzi njira; 10-20g wa lignocellulose amadzimadzi njira; 4-6g ya zothandizira kupanga mafilimu; 1.5-2.5 g wa antiseptic fungicide; 1.8-2.2g ya dispersant; 1.8-2.2g ya chonyowetsa; Thickener 3.5-4.5g; ethylene glycol 9-11g; The Building grade MHEC solution yamadzimadzi imapangidwa ndi 2-4% Kumanga kalasi ya MHEC kusungunuka m'madzi; ndicellulose fibernjira yamadzimadzi imapangidwa ndi 1 -3%cellulose fiberamapangidwa ndi kusungunuka m'madzi.

Momwe mungapangireKumanga kalasi ya MHEC?

ThekupangaNjira Yomanga kalasi ya MHEC methyl hydroxyethyl cellulose ndikuti thonje loyengedwa limagwiritsidwa ntchito ngati zopangira ndipo ethylene oxide imagwiritsidwa ntchito ngati etherifying agent pokonzekera Kumanga kalasi ya MHEC. Zopangira zopangira Kumanga kalasi ya MHEC zimakonzedwa m'magawo ndi kulemera kwake: magawo 700-800 a toluene ndi isopropanol osakaniza monga zosungunulira, magawo 30-40 a madzi, magawo 70-80 a sodium hydroxide, magawo 80-85 a thonje loyengeka, mphete 20-28 mbali za oxyethane, 80-90 magawo a methyl chloride, 16-19 magawo a glacial asidi; masitepe enieni ndi awa:

Mu sitepe yoyamba, onjezani chisakanizo cha toluene ndi isopropanol, madzi, ndi sodium hydroxide mu ketulo zomwe zimachitikira, kwezani kutentha kwa 60-80 ° C, ndikusunga kwa mphindi 20-40;

Gawo lachiwiri, alkalization: kuziziritsa zida zomwe zili pamwambapa mpaka 30-50 ° C, onjezani thonje woyengedwa, kupoperani ndi toluene ndi isopropanol, tulukani ku 0.006Mpa, lembani nayitrogeni m'malo atatu, ndikuchita alkalis mutatha kusintha. ndi motere: nthawi alkalization ndi 2 hours, ndi alkalization kutentha ndi 30 ℃-50 ℃;

Gawo lachitatu, etherification: pambuyo pa alkalization, riyakitala imasamutsidwa kupita ku 0.05～0.07MPa, ethylene oxide ndi methyl chloride amawonjezeredwa ndikusungidwa kwa 30.～Mphindi 50; Gawo loyamba la etherification: 40～60 ℃, 1.0～Maola a 2.0, kupanikizika kumayendetsedwa pakati pa 0.15-0.3Mpa; Gawo lachiwiri la etherification: 60～90 ℃, 2.0～Maola a 2.5, kupanikizika kumayendetsedwa pakati pa 0,4-0.8Mpa;

Gawo lachinayi, kusalowerera ndale: onjezerani metered glacial acetic acid pasadakhale ku desolventizer, kanikizani muzinthu zomwe zili ndi etherified for neutralization, onjezerani kutentha mpaka 75.～80 ℃ pakuwonongeka, kutentha kudzakwera kufika pa 102 ℃, ndipo pH mtengo udzakhala 68. Pamene chiwonongeko chatha; Dzazani ketulo yowononga ndi madzi apampopi opangidwa ndi chipangizo cha reverse osmosis pa 90 ℃～100 ℃;

Gawo lachisanu, kutsuka kwa centrifugal: zipangizo mu sitepe yachinayi ndi centrifuged ndi yopingasa wononga centrifuge, ndipo olekanitsidwa zipangizo amasamutsidwa ndi kutsuka ketulo wodzazidwa ndi madzi otentha pasadakhale kutsuka zipangizo;

Gawo lachisanu ndi chimodzi, kuyanika kwa centrifugal: zida zotsuka zimatumizidwa mu chowumitsira kudzera muzitsulo zopingasa centrifuge, zida zouma pa 150-170 ° C, ndipo zouma zouma zimaphwanyidwa ndi kupakidwa.

Poyerekeza ndi ukadaulo wopangira ma cellulose ether, wapanonjira yopangaamagwiritsa okusayidi ethylene monga wothandizila etherifying kukonzekera Kumanga kalasi MHEC methyl hydroxyethyl mapadi, ndipo chifukwa lili magulu hydroxyethyl, ali ndi mphamvu antifungal wabwino. Kukhazikika kwa viscosity yabwino komanso kukana kwa mildew pakusungidwa kwanthawi yayitali. Ikhoza kulowa m'malo ena a cellulose ether.

Bmaphunziro apamwamba a MHECndi zotumphukira za cellulose ether,Cellulose ether ndi mankhwala opangidwa ndi polima abwino omwe amagwiritsidwa ntchito mosiyanasiyana opangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera mumankhwala. Popeza cellulose nitrate ndi cellulose acetate zinapangidwa m'zaka za zana la 19, akatswiri a zamankhwala apanga zotuluka zambiri za cellulose za cellulose ethers. Magawo atsopano ogwiritsira ntchito akupezeka nthawi zonse ndipo magawo ambiri ogulitsa akukhudzidwa. Ma cellulose ether monga sodium carboxymethyl cellulose (CMC), ethyl cellulose (EC), hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), methyl hydroxyethyl cellulose (MHEC) Ndipo methyl hydroxypropyl cellulose (MHPC) ndi ma cellulose ethers amadziwika kuti "Industrial monosodium glutamate" ndi kalasi yomanga MHEC akhala ambiri ntchito zomatira matailosi, matope youma, simenti ndi gypsum plasters etc.
