Methyl hydroxyethyl cellulose (MHEC) ndi gawo lofunikira la cellulose ether yokhala ndi zosintha ziwiri za methylation ndi hydroxyethylation.Mu zokutira zokhala ndi madzi, MHEC imagwira ntchito yofunika kwambiri ndi mawonekedwe ake apadera a thupi ndi mankhwala.
I. Makhalidwe amachitidwe
Kukhuthala
Magulu a hydroxyethyl ndi methyl mu kapangidwe ka molekyulu ya MHEC amatha kupanga maukonde munjira yamadzimadzi, potero akuwonjezera kukhuthala kwa zokutira.Kukhuthala kumeneku kumathandizira kuti ikwaniritse bwino ma rheology pamalo otsika, potero kuchepetsa kuchuluka kwa zokutira ndikupulumutsa ndalama.
Kusintha kwa Rheological
MHEC imatha kupereka zokutira zabwino kwambiri zamadzimadzi komanso anti-sagging.Makhalidwe ake a pseudoplastic amapanga ❖ kuyanika kukhala ndi mamasukidwe apamwamba kwambiri m'malo osasunthika, ndipo kukhuthala kungathe kuchepetsedwa panthawi yogwiritsira ntchito, yomwe ndi yabwino kwa brushing, ❖ kuyanika kapena kupopera mankhwala, ndipo potsiriza akhoza kubwezeretsa kukhuthala koyambirira pambuyo pomanga. kumaliza, kuchepetsa kugwa kapena kudontha.
Kusunga madzi
MHEC ili ndi malo abwino osungira madzi ndipo imatha kuwongolera bwino kuchuluka kwa madzi.Katunduyu ndi wofunikira kwambiri poletsa utoto wopangidwa ndi madzi kuti usakanike, ufa ndi zolakwika zina panthawi yowumitsa, komanso zimatha kuwongolera bwino komanso kufananiza kwa zokutira pakumanga.
Kukhazikika kwa emulsion
Monga surfactant, MHEC ikhoza kuchepetsa kuthamanga kwa pigment particles mu utoto wopangidwa ndi madzi ndikulimbikitsa kufalikira kwawo yunifolomu m'zinthu zoyambira, potero kumapangitsa kuti utoto ukhale wokhazikika komanso wosasunthika komanso kupewa kuyandama ndi mpweya wa pigment.
Biodegradability
MHEC imachokera ku cellulose yachilengedwe ndipo ili ndi biodegradability yabwino, yomwe imapangitsa kuti ikhale ndi ubwino woonekeratu mu utoto wamadzi otetezedwa ndi chilengedwe ndipo imathandizira kuchepetsa kuipitsidwa kwa chilengedwe.
2. Ntchito zazikulu
Thickener
MHEC imagwiritsidwa ntchito makamaka ngati chowonjezera cha utoto wopangidwa ndi madzi kuti apititse patsogolo ntchito yake yomanga komanso mawonekedwe afilimu powonjezera kukhuthala kwa utoto.Mwachitsanzo, kuwonjezera MHEC ku utoto wa latex kumatha kupanga zokutira yunifolomu pakhoma kuti penti isagwere komanso kugwa.
Rheology wowongolera
MHEC ikhoza kusintha rheology ya utoto wopangidwa ndi madzi kuti iwonetsetse kuti ndi yosavuta kugwiritsa ntchito panthawi yomanga ndipo ikhoza kubwereranso ku chikhalidwe chokhazikika.Kupyolera mu kayendetsedwe ka rheological, MHEC imapangitsa kuti ntchito yomanga ikhale yabwino, ndikupangitsa kuti ikhale yoyenera njira zosiyanasiyana zokutira.
Wosunga madzi
Muzitsulo zokhala ndi madzi, malo osungira madzi a MHEC amathandizira kuwonjezera nthawi yokhalamo yamadzi mu zokutira, kupititsa patsogolo kuyanika kofanana ndi chophimba, komanso kuteteza kubadwa kwa ming'alu ndi zowonongeka.
Stabilizer
Chifukwa cha luso lake labwino la emulsifying, MHEC ikhoza kuthandizira zokutira zokhala ndi madzi kupanga dongosolo lokhazikika la emulsion, kupeŵa mpweya ndi flocculation ya pigment particles, ndi kupititsa patsogolo kukhazikika kwa kusunga kwa zokutira.
Thandizo pakupanga mafilimu
Panthawi yopangira filimu yophimba, kukhalapo kwa MHEC kungalimbikitse kufanana ndi kusalala kwa chophimba, kotero kuti chophimba chomaliza chikhale ndi maonekedwe abwino ndi ntchito.
3. Zitsanzo zogwiritsira ntchito
utoto wa latex
Mu utoto wa latex, ntchito yayikulu ya MHEC ndikukula komanso kusunga madzi.Ikhoza kupititsa patsogolo kupukuta ndi kugudubuza kwa utoto wa latex, ndikuonetsetsa kuti zokutira zimakhalabe zosalala komanso zofanana panthawi yowumitsa.Kuphatikiza apo, MHEC imathanso kupititsa patsogolo zotsutsana ndi kuwomba ndi kugwa kwa utoto wa latex, ndikupangitsa kuti ntchito yomanga ikhale yosavuta.
Utoto wamatabwa wamadzi
Mu utoto wamatabwa wopangidwa ndi madzi, MHEC imapangitsa kuti filimuyo ikhale yosalala komanso yofananira posintha kukhuthala ndi rheology ya utoto.Zitha kulepheretsanso utoto kuti zisagwe ndi kuipitsidwa pamitengo, ndikuwonjezera kukongoletsa komanso kulimba kwa filimuyo.
Utoto wopangidwa ndi madzi
Kugwiritsa ntchito kwa MHEC mu utoto womanga wopangidwa ndi madzi kumatha kupititsa patsogolo ntchito yomanga komanso kuyanika kwa utoto, makamaka poyala malo monga makoma ndi denga, kumatha kuletsa kugwa ndi kudontha kwa utoto.Kuonjezera apo, katundu wosungira madzi wa MHEC angathenso kuwonjezera nthawi yowumitsa utoto, kuchepetsa kusweka ndi kuwonongeka kwa pamwamba.
Utoto wamakampani opangidwa ndi madzi
Mu utoto wamakampani opangidwa ndi madzi, MHEC sikuti imangogwira ntchito ngati thickener ndi kusungira madzi, komanso imathandizira kufalikira ndi kukhazikika kwa utoto, kotero kuti utoto ukhoza kukhala ndi magwiridwe antchito komanso kukhazikika m'malo ovuta a mafakitale.
IV.Zoyembekeza zamsika
Ndi malamulo omwe akuchulukirachulukira oteteza chilengedwe komanso kufunikira kwa zida zomangira zobiriwira, kufunikira kwa msika wa utoto wopangidwa ndi madzi kukukulirakulira.Monga chowonjezera chofunikira mu utoto wamadzi, MHEC ili ndi chiyembekezo chachikulu chamsika.
Kukwezeleza mfundo za chilengedwe
Padziko lonse lapansi, ndondomeko za chilengedwe zakhwimitsa kwambiri zoletsa za volatile organic compound (VOC), zomwe zalimbikitsa kugwiritsa ntchito zokutira zamadzi.Monga chowonjezera chothandizira zachilengedwe, MHEC imagwira ntchito yofunika kwambiri pakuyala m'madzi, ndipo kufunikira kwake kudzachulukirachulukira ndikukula kwa msika wa zokutira zam'madzi.
Kukula kofunikira mumakampani omanga
Kufunika kowonjezereka kwa VOC yotsika, zokutira zogwira ntchito kwambiri pantchito yomanga kwalimbikitsanso kugwiritsa ntchito MHEC muzopaka zomangira zam'madzi.Makamaka zokutira mkati ndi kunja kwa khoma, MHEC imatha kupereka ntchito yabwino yomanga komanso kulimba kuti ikwaniritse zomwe msika ukufunikira.
Kukulitsa kugwiritsa ntchito zokutira zamakampani
Kufunika kwakukula kwa zokutira zoteteza zachilengedwe m'mafakitale kwalimbikitsanso kugwiritsa ntchito kwa MHEC mu zokutira zamafakitale zamadzi.Pamene zokutira zamafakitale zikupita kumayendedwe okonda zachilengedwe komanso magwiridwe antchito apamwamba, MHEC itenga gawo lalikulu pakuwongolera magwiridwe antchito komanso mawonekedwe a chilengedwe.
Methyl hydroxyethyl cellulose (MHEC) imagwira ntchito yofunika kwambiri pakupaka m'madzi ndi makulidwe ake abwino kwambiri, kusintha kwa rheology, kusunga madzi, kukhazikika kwa emulsion ndi biodegradability.Kugwiritsiridwa ntchito kwake mu zokutira zokhala ndi madzi sikungowonjezera ntchito yomanga ndi kuyatsa khalidwe la zokutira, komanso zimagwirizana ndi chikhalidwe cha chitetezo cha chilengedwe ndi chitukuko chokhazikika.Chifukwa chakukula kwa msika wa zokutira zokhala ndi magwiridwe antchito apamwamba, zotsika za VOC zokhala ndi madzi, ziyembekezo zakugwiritsa ntchito kwa MHEC m'gawoli zikhala zokulirapo.
