Kuwongolera kusefera: HEC imatha kuwongolera bwino kusefera kwamadzi obowola, kuchepetsa kuipitsidwa kwa mapangidwe, ndikuwongolera kukhazikika ndi kupanga mphamvu ya zitsime zamafuta.
Kusintha kwa Rheological: HEC imatha kusintha kamvekedwe kamadzimadzi obowola ndi kuphulika kwamadzimadzi, kukulitsa mphamvu yake yonyamula mchenga, ndikuwongolera magwiridwe antchito komanso magwiridwe antchito a fracturing.
2.3 Makampani omanga
M'makampani omanga, HEC imagwiritsidwa ntchito nthawi zambiri mumatope a simenti, zinthu za gypsum ndi utoto wa latex. Ntchito zake zazikulu ndi izi:
Kuchulukitsa ndi kusunga madzi: HEC imatha kupititsa patsogolo kusasinthika kwa matope ndi gypsum, kuwonjezera magwiridwe antchito pakumanga, ndikuwonjezera kusungirako madzi, kuteteza kutayika kwa madzi, komanso kukulitsa mphamvu zomangira.
Anti-sagging: Mu utoto wa latex, HEC imatha kuletsa utoto kuti usagwedezeke pamtunda, kusunga yunifolomu yokutira, ndikuwongolera zomangamanga.
Kumangirira kowonjezereka: HEC imatha kukonza mgwirizano pakati pa matope a simenti ndi gawo lapansi, kuonjezera mphamvu ndi kulimba kwa zinthuzo.
2.4 Daily Chemical Viwanda
Kugwiritsa ntchito kwakukulu kwa HEC pazamankhwala atsiku ndi tsiku kumaphatikizapo kugwiritsidwa ntchito ngati thickener, stabilizer ndi emulsifier kwa zotsukira, shamposi, mafuta odzola ndi zodzoladzola. Ntchito zake zikuphatikizapo:
Kukhuthala: HEC imatha kukulitsa kukhuthala kwa zinthu zatsiku ndi tsiku, ndikupangitsa kuti mawonekedwe ake akhale osakhwima komanso abwino kugwiritsa ntchito.
Kukhazikika: HEC imakhala ndi kusungunuka kwamadzi bwino komanso chitetezo cha colloid, imatha kukhazikika kachitidwe ka emulsified, kupewa kulekanitsa kwamadzi ndi mafuta, ndikuwonjezera moyo wa alumali wazinthuzo.
Kuyimitsidwa: HEC imatha kuyimitsa tinthu tating'onoting'ono, kupititsa patsogolo kubalalitsidwa ndi kufanana kwa chinthucho, ndikuwongolera mawonekedwe ndi mawonekedwe.
2.5 Makampani Opanga Mankhwala
M'makampani opanga mankhwala, HEC imagwiritsidwa ntchito makamaka ngati chomangira komanso chotulutsa nthawi zonse, gelling agent ndi emulsifier pamapiritsi. Ntchito zake zikuphatikizapo:
Kumanga: HEC imatha kumanga tinthu tating'onoting'ono tamankhwala ndikuwongolera mphamvu zamakina ndi kuwonongeka kwa mapiritsi.
Kumasulidwa kokhazikika: HEC ikhoza kusintha mlingo wotulutsidwa ndi mankhwala, kukwaniritsa zotsatira zokhazikika kapena zoyendetsedwa bwino, ndikuwongolera mphamvu ya mankhwala ndi kumvera kwa odwala.
Gel ndi emulsification: HEC ikhoza kupanga gel osakaniza kapena emulsion mu kapangidwe ka mankhwala, kupititsa patsogolo kukhazikika ndi kukoma kwa mankhwala.
3. Ubwino ndi makhalidwe
3.1 Kukula kwabwino kwambiri komanso mawonekedwe a rheological
HEC ili ndi mphamvu zabwino kwambiri zowonjezeretsa komanso kusintha kwa rheological, zomwe zingathe kuonjezera kukhuthala kwa njira zamadzimadzi, zomwe zimawapangitsa kukhala ngati madzi a pseudoplastic pamitengo yotsika kwambiri ya shear ndi madzi a Newtonian pamtengo wokwera kwambiri. Izi zimathandiza kuti akwaniritse zofunikira za rheological za ntchito zosiyanasiyana zamakampani.
3.2 Kukhazikika ndi kuyanjana
HEC ili ndi kukhazikika kwa mankhwala abwino, ikhoza kukhalabe yokhazikika pa pH yochuluka, ndipo imagwirizana ndi mankhwala osiyanasiyana ndi zosungunulira. Izi zimathandiza kukhalabe khola thickening ndi stabilizing zotsatira zovuta mankhwala machitidwe.
3.3 Kuteteza chilengedwe ndi chitetezo
HEC imapangidwa ndi cellulose yachilengedwe, ili ndi biodegradability yabwino komanso yosunga zachilengedwe. Panthawi imodzimodziyo, HEC ndi yopanda poizoni komanso yopanda vuto, ndipo ndi yoyenera kwa mankhwala a tsiku ndi tsiku ndi mankhwala omwe ali ndi zofunikira zachitetezo.
Hydroxyethyl cellulose (HEC) ili ndi ntchito zosiyanasiyana ndipo imagwira ntchito yofunika kwambiri pamakampani opanga mankhwala. Kukula kwake kwabwino kwambiri, rheological properties, kukhazikika ndi kugwirizanitsa kumapangitsa kuti zikhale zofunikira zowonjezera m'mafakitale ambiri monga zokutira, mafuta, zomangamanga, mankhwala a tsiku ndi tsiku ndi mankhwala. Ndi chitukuko chaukadaulo komanso kusintha kwa kufunikira kwa msika, chiyembekezo chogwiritsa ntchito HEC chidzakhala chokulirapo.
