Chowonjezera chamtundu wa humic acid ndi mtundu wamafuta a polima bwino a simenti otayika omwe akhala akutchuka m'zaka zaposachedwa.Monga chimodzi mwazinthu zatsopano za Oilbayer, kampani yomwe imagwira ntchito bwino pa R&D ndikupanga mankhwala opangira mafuta, chowonjezera chotayika chamadzi ichi chidapangidwa kuti chithandizire oyendetsa mafuta ndi gasi pakufuna kuchita bwino kwambiri.
Zowonjezera zamtunduwu zimapangidwa kuchokera ku kuphatikiza kwa AMPS/NN/humic acid ndi kutentha kwabwino komanso kukana mchere.The humic acid imakhala ngati monomer wamkulu, pomwe ma monomer ena osamva mchere amaphatikizidwa kuti apititse patsogolo mphamvu zake.Zotsatira zake ndi chowonjezera chothandiza kwambiri chomwe chingathandize kuchepetsa kutayika kwamadzimadzi panthawi yopangira simenti, potero kumapangitsa kuti chitsime chiziyenda bwino komanso kubweza ndalama zonse.
Kutayika kwamadzi ndi vuto lofala m'makampani amafuta ndi gasi, makamaka panthawi ya simenti.Zimachitika pamene madzi omwe amagwiritsidwa ntchito pomanga chitsime amalowa m'matanthwe, ndikusiya zipsinjo zomwe zimachepetsa mphamvu ya simenti.Izi zitha kubweretsa zovuta zingapo, monga kuchepa kwa zokolola, kuchuluka kwa ndalama zolipirira, komanso zovuta zamakhalidwe abwino.
Chowonjezera chamadzimadzi chamtundu wa humic acid chimathandizira kuchepetsa mavutowa popanga chitetezo chozungulira chitsime.Chigawochi chimakhala ngati chotchinga, chomwe chimalepheretsa madzi a simenti kuti asalowe m'mapangidwe komanso kuchepetsa kuchuluka kwa madzi omwe amatayika panthawi yopangira simenti.Izi zimatheka chifukwa cha kuphatikiza kwapadera kwa polima, zomwe zimathandizira kukulitsa kukhuthala kwamadzimadzi a simenti ndikuletsa kuti zisalowe m'chitsime.
Ubwino wina waukulu wogwiritsa ntchito zowonjezera zamtundu wa humic acid ndi kutentha kwawo komanso kukana mchere.Izi zikutanthauza kuti angagwiritsidwe ntchito m'madera osiyanasiyana, kuphatikizapo mapangidwe otentha kwambiri komanso omwe ali ndi mchere wambiri.Kusinthasintha kumeneku kumawapangitsa kukhala chisankho chabwino kwa ogwiritsa ntchito mafuta ndi gasi omwe amayang'ana kuti achulukitse bwino ntchito yawo yobowola.
Pomaliza, chowonjezera chamtundu wa humic acid ndi njira yabwino yothetsera vuto la kutaya madzimadzi lomwe limakumana ndi mafakitale amafuta ndi gasi.Yopangidwa ndi Oilbayer, mankhwalawa amaphatikiza phindu lapadera la AMPS / NN / humic acid ndi ma monomers ena osamva mchere kuti apange zowonjezera zowonjezera zomwe zingagwiritsidwe ntchito pazinthu zosiyanasiyana.Ngati mukufuna kukonza zogwirira ntchito zanu zobowola bwino, lingalirani zophatikizira zowonjezera zamtundu wa humic acid kutayika kwamadzimadzi muzochita zanu za simenti.
WOCHEZA WAPAKATI NDI WOTSIKA WA POLYMER FLUID KUTAYIKA
Ukadaulo wopangira simenti wamafuta a polima wakhala ukugwiritsidwa ntchito kwambiri pakufufuza ndi kukonza minda yamafuta ndi gasi.Chimodzi mwazinthu zofunika kwambiri paukadaulo wopangira simenti wa polima ndi anti-water loss agent, yomwe imatha kuchepetsa kutayika kwa madzi panthawi yopangira simenti.Kugwiritsa ntchito ukadaulo wa simenti ya polima kuli ndi zabwino zambiri monga kulimba kwambiri, kutsika pang'ono, komanso kusindikiza bwino kwambiri.Komabe, vuto lomwe anthu ambiri amakumana nalo pochita izi ndi kutaya madzi, ndiko kuti, matope a simenti amalowa mu mapangidwe, zomwe zimapangitsa kuti zikhale zovuta kutulutsa chubu panthawi yobwezeretsa mafuta.Chifukwa chake, kukulitsa kwapakati komanso kutsika kwamadzi ochepetsera kutentha kwakhala komwe kumayang'ana kwambiri kupita patsogolo kwaukadaulo wopangira simenti.
Polima mafuta bwino simenti madzimadzi kutaya reducer:
Kutayika kwamadzimadzi ndi chinthu chofunikira kwambiri pokonzekera slurry ya simenti.Ndi ufa womwe umasungunuka mosavuta m'madzi ndipo uli ndi zinthu zabwino zosakaniza.Pa mapangidwe, madzimadzi kutaya ulamuliro wothandizila kusakaniza ndi zigawo zina kupanga homogeneous ndi khola simenti slurry.Wowongolera kutaya kwamadzimadzi amagwira ntchito yofunika kwambiri pakuchepetsa kutayika kwamadzimadzi panthawi yomanga simenti.Amachepetsa kusamuka kwa madzi mumatope kupita ku mapangidwe ozungulira ndikuwongolera makina a simenti.
Kutaya madzi ≤ 50:
Mukamagwiritsa ntchito zochepetsera zamadzimadzi, ndikofunikira kuyang'anira kuchuluka kwamadzi otayika mkati mwamitundu ina, nthawi zambiri zosakwana kapena zofanana ndi 50ml/30min.Ngati madzi atayika kwambiri, matope a simenti amatha kulowa m'kati mwake, zomwe zimapangitsa kuti zibowo ziziyenda bwino, matope, ndi kulephera kwa simenti.Kumbali ina, ngati madzi otaya madzi ndi otsika kwambiri, nthawi ya simenti idzawonjezeka, ndipo wothandizira wotsutsa-kutayika wamadzi amafunikira, zomwe zimawonjezera mtengo wa ndondomeko.
Chochepetsa kutentha kwapakati ndi kutsika kwamadzimadzi:
Panthawi yopangira simenti m'minda yamafuta, kutayika kwa madzi kumakhudzidwa ndi zinthu zosiyanasiyana monga kutentha kwa mapangidwe, kupanikizika, ndi permeability.Makamaka, kutentha kwa simenti yamadzimadzi kumakhudza kwambiri kutayika kwamadzimadzi.Kutayika kwamadzimadzi kumawonjezeka kwambiri pa kutentha kwakukulu.Choncho, pokonza simenti, m'pofunika kugwiritsa ntchito zowonjezera zowonjezera komanso zotsika kutentha kwamadzimadzi zomwe zingathe kuchepetsa kutayika kwa madzi pa kutentha kwakukulu.
Powombetsa mkota:
Mwachidule, ukadaulo wopangira simenti wamafuta a polima wakhala umodzi mwamaukadaulo ofunikira pakufufuza ndi chitukuko chamafuta ndi gasi.Chimodzi mwazinthu zazikulu zaukadaulowu ndi anti-water loss agent, yomwe imathandizira kwambiri kuchepetsa kutayika kwa madzi panthawi yomanga simenti.Kuwongolera kutayika kwa madzi pokonza matope kumathandizanso kwambiri kuti ntchito yomanga simenti ikhale yopambana.Kupanga zida zochepetsera kutentha kwapakati komanso kutsika ndikofunikira kwambiri pakuwongolera simenti, kuchepetsa ndalama komanso kuwongolera kukhulupirika kwa zitsime zamafuta ndi gasi.
