Ngesikhathi sokumba, ukumba kanye nokusebenza kukawoyela kanye negesi yemvelo, udonga olunzulu luthambekele ekulahlekelweni kwamanzi, okubangela ushintsho ebubanzilweni obuhle futhi buwe, ukuze iphrojekthi ingenzeke ngokujwayelekile, noma ishiywe phakathi. Ngakho-ke, kuyadingeka ukuguqula amapharamitha angokomzimba wodaka oludonsayo ngokuya ngezinguquko ezimeni zenkamo zesifunda ngasinye, njengokujula, izinga lokushisa, nobukhulu. I-CMC ingumkhiqizo omuhle kakhulu ongaguqula la mapharamitha angokwenyama. Imisebenzi yayo eyinhloko yile:
Udaka oluqukethe i-CMC lungenza i-Wall Wall Enhle ibe yikhekhe elincanyana, eliqinile futhi eliphansi le-mpobusity, elingavimba ukumba kwe-shale, kuvikele ukusika kokumba kusuka ekusakazeni, futhi kunciphise ukuwa kodonga kahle.
Udaka oluqukethe i-CMC luhlobo lwe-ejenti yokulawula ukulahleka okuphezulu, lungalawula ukulahleka kwamanzi esigabeni esingcono emthanjeni ophansi (0.3-0.5%), futhi ngeke kubangele imiphumela emibi kakhulu kadaka, njengokuthola amandla aphezulu kakhulu noma amandla aphezulu.
Udaka oluqukethe i-CMC lungamelana nezinga lokushisa eliphakeme, futhi ngokujwayelekile lingasetshenziswa endaweni yokushisa ephezulu ye-140 ° C, njengokuthatha indawo ephezulu kanye nemikhiqizo ephezulu ye-viscosity, ingasetshenziswa endaweni yokushisa ephezulu ka-150-170 ° C.
Udaka oluqukethe i-CMC lumelana nosawoti. Izici ze-CMC ngokuya ngokumelana nosawoti yilezi: Akukhona kuphela ukuthi kungagcina amandla amahle okunciphisa ukulahleka kwamanzi ngaphansi kokuhlushwa kwamasamba, kodwa futhi kungagcina impahla ye-rherological, enoshintsho oluncane, olunoshintsho oluncane ngokuqhathaniswa nemvelo yamanzi ahlanzekile; Kokubili kungasetshenziswa uketshezi lokumba olungenama-Clay-free kanye nodaka endaweni yamanzi asawoti. Amanye amanzi okushayela asamelana nosawoti, kanye nezinto ezimbongikazi azishintshi okuningi. Ngaphansi kwama-4% okuhlushwa usawoti kanye namanzi amasha, isilinganiso sokushintsha kwesilinganiso se-CMC engamelana nosawoti sikhuphuke saba ngaphezu kwe-1, okungukuthi, i-viscosity ayikwazi ukushintshwa endaweni enosawoti ephakeme.
Udaka oluqukethe i-CMC lungalawula i-Rheology kadaka.Cmayikwazi ukunciphisa ukulahleka kwamanzi kuphela, kepha futhi kwandise ukubonakala.
1. Udaka oluqukethe i-CMC lungenza kahle udonga lwekhekhe lukhuni, lukhuni futhi oluphansi lwekhekhe, lunciphisa ukulahleka kwamanzi. Ngemuva kokungeza i-CMC odakeni, ukumba i-rig kungathola amandla aphansi okuqala, ukuze odaka akwazi ukukhulula igesi esongelwe kulo, futhi ngasikhathi sinye, imfucumfucu ingalahlwa ngokushesha emgodini odaka.
2. Njengokunye ukuhlukaniswa okumisiwe, udaka lokumba kunempilo ethile eshalofini. Ukungeza i-CMC kungenza ukuthi zinzile futhi kunwebe impilo yeshalofu.
3
I-4. I-CMC-equkethe udaka inokuqina okuhle futhi inganciphisa ukulahleka kwamanzi noma ngabe amazinga okushisa angaphezulu kwama-degree angama-150.
