Methyl Hydroxyethyl Cellulose (MHEC) ndi chokhuthala komanso zomatira zomwe zimagwiritsidwa ntchito pomanga. Kuyamba kwake kumakhudza kwambiri mphamvu za matrix a simenti.
1. Kupititsa patsogolo madzi ndi ntchito
Methyl hydroxyethyl cellulose, monga thickener, akhoza kwambiri kusintha fluidity wa simenti masanjidwewo. Zimapangitsa slurry ya simenti kukhala yokhazikika komanso yamadzimadzi panthawi yomanga powonjezera kukhuthala kwa kusakaniza. Izi zimathandiza kudzaza nkhungu zovuta komanso kuchepetsa spatter panthawi yomanga. Kuphatikiza apo, methyl hydroxyethyl cellulose imathanso kupititsa patsogolo kusungidwa kwamadzi kwa matrix a simenti ndikuchepetsa kutuluka kwa magazi kwa slurry ya simenti, motero kumapangitsa kuti zomangamanga ziziyenda bwino.
2. Sinthani kumamatira
Methyl hydroxyethyl cellulose imatha kupititsa patsogolo kwambiri kulumikizana kwa matrix a simenti. Izi ndichifukwa choti ili ndi zomatira zabwino kwambiri ndipo imatha kuphatikiza ndi chinyezi mu simenti kupanga colloid yokhala ndi zomatira zolimba. Kusintha kumeneku ndikofunikira kwambiri pakuwongolera kumamatira pakati pa masanjidwe a simenti ndi gawo lapansi, makamaka pakupaka khoma, kupaka matailosi a ceramic ndi ntchito zina.
3. Zimakhudza mphamvu ndi kulimba
Kuphatikiza kwa methylhydroxyethylcellulose kumakhudzanso mphamvu ya matrix a simenti. Mkati mwa mlingo wina, methylhydroxyethyl cellulose imatha kupititsa patsogolo mphamvu yopondereza ndi mphamvu yosunthika ya matrix a simenti. Powonjezera kufanana ndi kukhazikika kwa phala la simenti, kumachepetsa pores ndi ming'alu ya matrix a simenti, potero kumawonjezera mphamvu zonse ndi kulimba kwa zinthuzo. Komabe, ngati zochulukirapo ziwonjezeredwa, zingayambitse kuchepa kwa mgwirizano pakati pa simenti ndi kuphatikizira mu matrix a simenti, motero zimakhudza mphamvu zake zomaliza.
4. Limbikitsani kukana kwa ming'alu ya matrix a simenti
Popeza methylhydroxyethylcellulose imatha kusintha kusungidwa kwamadzi kwa matrix a simenti, imatha kuchepetsa ming'alu yomwe imayamba chifukwa cha kuyanika pang'ono. Kuyanika kuchepa kwa matrix a simenti ndi chimodzi mwazomwe zimayambitsa ming'alu, ndipo methylhydroxyethyl cellulose imathandizira kuchepetsa chiopsezo cha ming'alu yomwe imayamba chifukwa cha kuyanika kwamadzi pochepetsa kutuluka kwamadzi mwachangu.
5. Kuwongolera kwa Bubble mu masanjidwe a simenti
Methyl hydroxyethyl cellulose imatha kupanga chithovu chokhazikika m'matrix a simenti, zomwe zimathandiza kupititsa patsogolo kutsekeka kwa mpweya wa matrix a simenti. Katundu wowongolera kuwira kwa mpweya uku amathandizira kuwongolera kutentha kwa matrix a simenti ndikuchepetsa kuchulukira kwa matrix a simenti. Komabe, thovu lochulukirachulukira limatha kupangitsa kuti zinthuzo zithe mphamvu, chifukwa chake kuchuluka koyenera kumafunika kuonjezedwa kutengera ntchito yake.
6. Kupititsa patsogolo kusakwanira
Pakuwongolera kusungidwa kwamadzi kwa matrix a simenti, methylhydroxyethylcellulose imatha kuchepetsa kukwanira kwa matrix a simenti. Izi ndizofunikira kwambiri kuti pakhale kusasunthika komanso kusagwira madzi kwa matrix a simenti, makamaka pamapulogalamu omwe amafunikira kutsekereza madzi, monga zipinda zapansi, makoma akunja, ndi zina zambiri.
Kugwiritsa ntchito methylhydroxyethyl cellulose mu masanjidwe a simenti kungabweretse kusintha kwa magwiridwe antchito osiyanasiyana, kuphatikiza kuwongolera madzi, kuwongolera kumamatira, kulimbitsa mphamvu, kuwongolera kukana kwa ming'alu, kuwongolera thovu ndikusintha kusakwanira. Komabe, kagwiritsidwe ntchito ndi kuchuluka kwake kuyenera kusinthidwa moyenerera malinga ndi zosowa zenizeni za kagwiritsidwe ntchito ndi zofunikira zakuthupi kuti mupeze zotsatira zabwino kwambiri. Kupyolera mu kuwonjezera ndi kukonzekera kwasayansi komanso koyenera, methyl hydroxyethyl cellulose imatha kupititsa patsogolo magwiridwe antchito onse a matrix a simenti ndikukwaniritsa zosowa zosiyanasiyana zamainjiniya.
