1. Mawu Oyamba
Methyl hydroxyethyl cellulose (MHEC), yomwe imadziwikanso kuti hydroxyethyl methyl cellulose (HEMC), ndi ether yosungunuka m'madzi ya nonionic cellulose. MHEC ndi semi-synthetic polima wopangidwa ndi momwe cellulose yachilengedwe imayendera ndi methanol ndi ethylene oxide. Chifukwa cha mawonekedwe ake apadera akuthupi ndi mankhwala, MHEC imagwiritsidwa ntchito kwambiri m'mafakitale ambiri.
2. Kapangidwe ka mankhwala ndi makhalidwe
MHEC ili ndi magulu a methoxy ndi hydroxyethoxy m'mapangidwe ake a maselo, omwe amachititsa kuti azikhala ndi madzi osungunuka komanso okhazikika a mankhwala. Kuyamba kwa maguluwa kumapangitsa kukhala ndi kukhuthala kwabwino, gelling, kuyimitsidwa, kubalalitsidwa ndi kunyowetsa katundu pansi pa kutentha kosiyana ndi pH. Makhalidwe enieni a MHEC ndi awa:
Kukulitsa: MHEC imatha kukulitsa kukhuthala kwa mayankho amadzimadzi, ndikupangitsa kuti ikhale yokhuthala kwambiri.
Kusungirako madzi: MHEC ili ndi mphamvu yabwino yosungira madzi ndipo ingalepheretse kutuluka kwa madzi.
Katundu wopanga filimu: MHEC imatha kupanga filimu yolimba, yowonekera ndikuwonjezera mphamvu yolimba ya zinthuzo.
Emulsification ndi kuyimitsidwa kukhazikika: MHEC ingagwiritsidwe ntchito kukhazikika kuyimitsidwa ndi emulsions.
Kugwirizana: MHEC ili ndi mgwirizano wabwino ndipo ingagwiritsidwe ntchito ndi zina zosiyanasiyana zowonjezera.
3. Kugwiritsa ntchito MHEC muzomangamanga
Dothi louma:
Thickener ndi chosungira madzi: Mu matope owuma, MHEC imagwiritsidwa ntchito makamaka ngati thickener ndi chosungira madzi kuti apititse patsogolo operability, adhesion and anti-slip properties of the mortar. Imawongolera magwiridwe antchito a anti-sagging a matope kudzera mukukhuthala kuti atsimikizire kukhazikika pakumanga. Panthawi imodzimodziyo, kusungirako bwino kwa madzi kungalepheretse kutaya madzi msanga komanso kuonetsetsa kuti matope amadzimadzi okwanira.
Kupititsa patsogolo ntchito yomanga: MHEC imatha kupititsa patsogolo kukhuthala kwamadzi komanso anti-sagging katundu wamatope, ndikuwongolera magwiridwe antchito ndi luso la zomangamanga.
Zomata matailosi:
Limbikitsani kumamatira: Pomatira matailosi, MHEC imathandizira kumatira ndi anti-sagging katundu, kulola matailosi kumamatira mwamphamvu kumakoma kapena pansi.
Kupititsa patsogolo ntchito yomanga: Itha kuwonjezera nthawi yotseguka ndi nthawi yosinthira, kupereka mwayi womanga.
Putty powder:
Limbikitsani kusungirako madzi: MHEC imawonjezera kusungirako madzi mu putty powder kuteteza kusweka ndi ufa panthawi yowumitsa.
Limbikitsani magwiridwe antchito: Sinthani magwiridwe antchito a ufa wa putty kudzera mukukhuthala.
Zida zodziyimira pawokha:
Control fluidity: MHEC ikhoza kusintha madzi ndi kukhuthala kwa zipangizo zodzipangira pansi kuti zitsimikizire kuti pansi ndi lathyathyathya komanso losalala.
4. Kugwiritsa ntchito MHEC pamakampani opanga zokutira
Utoto wotengera madzi:
Kukhuthala ndi kukhazikika: Mu utoto wopangidwa ndi madzi, MHEC imagwira ntchito ngati thickener ndi stabilizer kuwongolera kuyimitsidwa ndi kukhazikika kwa utoto ndikuletsa kusungunuka kwa ma pigment ndi fillers.
Sinthani rheology: Ithanso kusintha mawonekedwe a utoto, kuwongolera kusungunuka komanso kusalala.
Mtundu wa latex:
Limbikitsani kusungirako madzi ndi kupanga mafilimu: MHEC imawonjezera kusungirako madzi ndi kupanga mafilimu a utoto wa latex ndikuwongolera machitidwe odana ndi scrub a filimu ya utoto.
5. Kugwiritsa ntchito MHEC pobowola mafuta
Kubowola madzi:
Limbikitsani kukhuthala ndi kukhazikika: Pamadzi obowola mafuta, MHEC imathandizira kukhuthala ndi kukhazikika kwamadzi obowola, imathandizira kunyamula zodulidwa, ndikuletsa kugwa kwa khoma.
Chepetsani kutayika kwa kusefera: Kusungidwa kwake kwa madzi kumatha kuchepetsa kutayika kwa kusefera ndikuletsa kuwonongeka kwa mapangidwe.
Madzi omaliza:
Kupaka mafuta ndi kuyeretsa: MHEC imagwiritsidwa ntchito pomaliza madzimadzi kuti apititse patsogolo mafuta komanso kuyeretsa kwamadzimadzi.
6. Kugwiritsa ntchito MHEC pamakampani azakudya
Chowonjezera chakudya:
Zopangira mkaka ndi zakumwa: MHEC ikhoza kugwiritsidwa ntchito ngati chowonjezera muzakudya zamkaka ndi zakumwa kuti muwonjezere kukoma ndi kukhazikika.
Stabilizer:
Kwa odzola ndi pudding: MHEC imagwiritsidwa ntchito ngati chokhazikika muzakudya monga odzola ndi pudding kuwongolera kapangidwe kake.
7. Kugwiritsa ntchito MHEC mu mankhwala ndi zodzoladzola
Mankhwala osokoneza bongo:
Mapiritsi omangira ndi owongolera otulutsa: M'mankhwala, MHEC imagwiritsidwa ntchito ngati chomangira komanso chowongolera chotulutsa mapiritsi kuti athe kuwongolera kuchuluka kwa mankhwala.
Zodzoladzola:
Mafuta odzola ndi zonona: MHEC imagwiritsidwa ntchito ngati thickener ndi emulsion stabilizer mu zodzoladzola, ndipo amagwiritsidwa ntchito mu mafuta odzola, mafuta odzola ndi zinthu zina kuti apititse patsogolo maonekedwe ndi kukhazikika kwa mankhwalawa.
8. Kugwiritsa ntchito MHEC pamakampani opanga mapepala
Kupaka mapepala:
Kupititsa patsogolo ntchito zokutira: MHEC imagwiritsidwa ntchito popaka mapepala ngati thickener ndi zomatira kuti zikhale zosalala komanso zosindikiza za pepala.
Zowonjezera za Slurry:
Kupititsa patsogolo mphamvu zamapepala: Kuonjezera MHEC ku slurry yopanga mapepala kungapangitse mphamvu ndi kukana madzi kwa pepala.
9. Ubwino ndi kuipa kwa MHEC
Ubwino:
Zosiyanasiyana: MHEC ili ndi ntchito zingapo monga kukhuthala, kusunga madzi, kuyimitsidwa, emulsification, etc., ndipo ili ndi ntchito zambiri.
Ndiwochezeka ndi chilengedwe: MHEC ndi chinthu chosawonongeka komanso chosawononga chilengedwe.
Kukhazikika kwamphamvu: Kumawonetsa kukhazikika bwino pansi pa pH yosiyana ndi kutentha.
Zoyipa:
Mtengo wokwera: Poyerekeza ndi zokhuthala zachikhalidwe, mtengo wopangira MHEC ndiwokwera kwambiri.
Kugwirizana ndi Mankhwala Ena: M'mapangidwe ena, MHEC ikhoza kukhala ndi zovuta zokhudzana ndi mankhwala ena.
Chifukwa cha zinthu zake zabwino kwambiri zakuthupi komanso zamankhwala, methyl hydroxyethyl cellulose (MHEC) imagwiritsidwa ntchito kwambiri m'mafakitale ambiri monga zomangamanga, zokutira, mafuta, chakudya, mankhwala ndi kupanga mapepala. Monga thickener, chosungira madzi, binder ndi stabilizer, imapereka chithandizo chofunikira kwambiri pazogulitsa ndi njira zosiyanasiyana. Komabe, muzogwiritsira ntchito, kugwirizanitsa kwake ndi zosakaniza zina ndi zinthu zamtengo wapatali ziyenera kuganiziridwanso. M'tsogolomu, ndi kupita patsogolo kwa teknoloji ndi kusintha kwa msika, madera ogwiritsira ntchito MHEC akhoza kukulitsidwa.
