Panguva yekuchera, kuchera uye kugadzirisa mafuta negasi rechisikigo, madziro etsime anowanzo rasikirwa nemvura, zvichikonzera shanduko mudhayamita yetsime uye kudonha, zvekuti chirongwa hachigone kuitwa zvakanaka, kana kutosiyiwa pakati. Saka, zvakakosha kugadzirisa maparamita emuviri ematope ekuchera zvichienderana nekuchinja kwemamiriro enzvimbo yega yega, senge kudzika kwetsime, tembiricha, uye ukobvu. CMC ndicho chigadzirwa chakanakisa chinogona kugadzirisa maparamita aya emuviri. Mabasa ayo makuru ndeaya:
Madhaka ane CMC anogona kuita kuti madziro etsime ave keke rakatetepa, rakasimba uye risingapindi mvura yakawanda, izvo zvinogona kudzivirira shale hydration, kudzivirira zvidimbu zvekuboorwa kuti zvisapararire, uye kuderedza kuputsika kwemadziro etsime.
Madhaka ane CMC imhando yemushonga unodzora kurasikirwa nemvura unoshanda zvakanyanya, unogona kudzora kurasikirwa nemvura zviri nani nedoro rakaderera (0.3-0.5%), uye hauzokonzere migumisiro yakaipa pane zvimwe zvinhu zvedhaka, zvakaita sekukwidibira kwakanyanya kana simba rekuchekerera.
Madhaka ane CMC anogona kuramba kupisa kwakanyanya, uye kazhinji anogona kushandiswa munzvimbo inodziya zvakanyanya inosvika 140°C, senge zvigadzirwa zvinotsiva zvakanyanya uye zvinosviba zvakanyanya, zvinogona kushandiswa munzvimbo inodziya zvakanyanya ye150-170°C.
Madhaka ane CMC haagoni kubatwa nemunyu. Hunhu hweCMC maererano nekusabatwa nemunyu ndehwekuti: haingogone chete kuchengetedza kugona kwakanaka kwekuderedza kurasikirwa kwemvura pasi pehuwandu hwakati hwemunyu, asi inogonawo kuchengetedza hunhu hwerheological, husina shanduko huru kana tichienzanisa nehwemunzvimbo ine mvura yakachena; inogona kushandiswa mumvura isina ivhu uye mumatope munzvimbo ine mvura ine munyu. Mamwe madhiri ekuboorera achiri kukwanisa kuramba munyu, uye hunhu hwerheological hahuchinji zvakanyanya. Pasi pehuwandu hwemunyu nemunyu nemvura yakachena, chiyero chekuchinja kweviscosity cheCMC inodzivirira munyu chakawedzerwa kusvika kupfuura 1, kureva kuti, viscosity haigone kuchinjwa munzvimbo ine munyu wakawanda.
Madhaka ane CMC anogona kudzora rheology yedhaka.CMChaingogumiri pakuderedza kurasikirwa nemvura chete, asiwo inowedzera viscosity.
1. Madhaka ane CMC anogona kuita kuti madziro etsime aite keke refirita rakatetepa, rakaoma uye risingapindi mvura zvakanyanya, zvichideredza kurasikirwa nemvura. Mushure mekuwedzera CMC mudhaka, gomba rekuchera rinogona kuwana simba shoma rekutanga, kuitira kuti dhaka rigone kusunungura gasi rakaputirwa mariri zviri nyore, uye panguva imwe chete, marara anogona kuraswa nekukurumidza mugomba redhaka.
2. Kufanana nedzimwe nzira dzekuisa simbi mumadhaka, dhaka rekuchera rine nguva yakatarwa yekushanda. Kuwedzera CMC kunogona kuita kuti igare yakasimba uye kuwedzera nguva yekushanda kwayo.
3. Madhaka ane CMC haawanzo kukanganiswa nefungus, uye hapana chikonzero chekuchengetedza pH yakakwira uye kushandisa zvinochengetedza.
4. Madhaka ane CMC ane kugadzikana kwakanaka uye anogona kuderedza kurasikirwa nemvura kunyangwe tembiricha iri pamusoro pe150 degrees.
