Munguva yekuchera, kuchera uye kushanda kwemafuta uye gasi rechisikigo, tsime remadziro rinowanzoita kurasikirwa kwemvura, zvichiita kuti kuchinja kwegomba remvura uye kuputsika, kuitira kuti purojekiti irege kuitwa zvakajairika, kana kunyange kusiyiwa hafu.Naizvozvo, zvinodikanwa kugadzirisa zvimiro zvemuviri zvedhaka rekuchera zvinoenderana nekuchinja kwemamiriro e geological yedunhu rega rega, sekudzika kwakadzika, tembiricha, uye ukobvu.CMC ndicho chakanakisa chigadzirwa chinogona kugadzirisa aya emuviri paramita.Mabasa ayo makuru ndeaya:
Madhaka ane CMC anogona kuita kuti madziro emutsime aite mutete, akasimba uye akaderera-permeability sefa keke, anogona kudzivirira shale hydration, kudzivirira kuchera kuchekwa kubva pakupararira, uye kuderedza tsime kudonha kwemadziro.
Madhaka ane CMC imhando yemhando yepamusoro-inoshanda yekurasikirwa kwemvura yekudzora mumiriri, inogona kudzora kurasikirwa kwemvura pamwero uri nani pane yakaderera dosage (0.3-0.5%), uye haizokonzere kukanganisa kune zvimwe zvinhu zvedhaka. , senge yakawandisa viscosity kana shear simba.
CMC-ine madhaka anogona kuramba tembiricha yakakwira, uye kazhinji inogona kushandiswa munzvimbo ine tembiricha yepamusoro inosvika 140 ° C, senge yakakwira-inotsiva uye yakakwirira-viscosity zvigadzirwa, inogona kushandiswa munzvimbo inodziya yepamusoro ye150-170. °C.
Madhaka ane CMC anoshingirira munyu.Hunhu hweCMC maererano nekupikiswa kwemunyu ndeiyi: haingogone kuchengetedza kugona kwakanaka kwekudzikisa kurasikirwa kwemvura pasi peimwe munyu, asi inogona zvakare kuchengetedza imwe rheological pfuma, ine shanduko shoma kana ichienzaniswa neiyo munzvimbo yemvura yakachena. ;zviri zviviri Inogona kushandiswa mumvura isina ivhu yekuchera uye madhaka munzvimbo yemvura yemunyu.Mamwe madhiri ekuchera anogona kuramba munyu, uye rheological zvimiro hazvichinje zvakanyanya.Pasi pe 4% munyu yekuisa uye mvura yakachena, iyo viscosity shanduko chiyero chemunyu-inodzivirira CMC yakawedzera kusvika kupfuura 1, ndiko kuti, viscosity haigone kuchinjwa munzvimbo ine munyu wakanyanya.
CMC-ine dhaka inogona kudzora rheology yematope.CMChaigoni kuderedza kurasikirwa kwemvura chete, asiwo kuwedzera viscosity.
1. CMC-ine madhaka anogona kuita tsime rusvingo kuumba nhete, yakaoma uye yakaderera-permeability sefa keke, kuderedza kurasikirwa mvura.Mushure mekuwedzera CMC kune madhaka, iyo yekuchera inogona kuwana yakaderera yekutanga shear simba, kuitira kuti dhaka rikwanise kusunungura gasi rakaputirwa mukati maro, uye panguva imwe chete, marara anogona kukurumidza kuraswa mugomba rematope.
2. Kufanana nemamwe madhirigi ekumisa, madhaka ekuchera ane humwe hupenyu hwesherufu.Kuwedzera CMC kunogona kuita kuti igadzikane uye kurebesa hupenyu hwesherufu.
3. Madhaka ane CMC haanyanyi kukanganiswa ne mold, uye hapana chikonzero chekuchengetedza yakakwira pH kukosha uye kushandisa zvinodzivirira.
4. CMC-ine madhaka ane kugadzikana kwakanaka uye anogona kuderedza kurasikirwa kwemvura kunyange kana tembiricha iri pamusoro 150 madhigirii.
