Ngesikhathi sokumba, ukubhoboza nokusebenza kwamafutha kanye negesi yemvelo, udonga lomthombo luvame ukulahlekelwa amanzi, lubangele izinguquko kububanzi bomthombo kanye nokuwa, ukuze iphrojekthi ingakwazi ukuqhutshwa ngokujwayelekile, noma ishiywe ngisho nohhafu. Ngakho-ke, kuyadingeka ukulungisa imingcele ebonakalayo yodaka lokumba ngokuvumelana nezinguquko ezimweni ze-geological zesifunda ngasinye, njengokujula, izinga lokushisa, nokuqina. I-CMC ingumkhiqizo ongcono kakhulu ongalungisa lezi zinhlaka zomzimba. Imisebenzi yayo eyinhloko yilezi:
Udaka oluqukethe i-CMC lungenza udonga lomthombo lube ikhekhe lokuhlunga elincanyana, eliqinile nelincane, elingavimbela ukugeleza kwe-shale, kuvimbele ukusika ukumba ukuthi kungahlakazeka, futhi kunciphise ukubhidlika kodonga lomthombo.
Udaka oluqukethe i-CMC luwuhlobo lwe-ejenti yokulawula uketshezi olusebenza kahle kakhulu, lungalawula ukulahlekelwa kwamanzi ngezinga elingcono ngesilinganiso esiphansi (0.3-0.5%), futhi ngeke lubangele imiphumela emibi kwezinye izakhiwo zodaka , njenge-viscosity ephezulu kakhulu noma amandla okugunda.
Udaka oluqukethe i-CMC lungamelana nezinga lokushisa eliphezulu, futhi ngokuvamile lungasetshenziswa endaweni enezinga lokushisa eliphezulu elingaba ngu-140°C, njengemikhiqizo eshintsha kakhulu kanye ne-viscosity ephezulu, ingasetshenziswa endaweni enezinga lokushisa eliphezulu engu-150-170°C.
Udaka oluqukethe i-CMC alukwazi ukumelana nosawoti. Izici ze-CMC mayelana nokumelana nosawoti yilezi: hhayi nje kuphela ukuthi ingakwazi ukugcina ikhono elihle lokunciphisa ukulahlekelwa kwamanzi ngaphansi kokuhlushwa kukasawoti othile, kodwa futhi ingagcina impahla ethile ye-rheological, enoshintsho oluncane uma iqhathaniswa naleyo endaweni yamanzi ahlanzekile; kukokubili Ingasetshenziselwa uketshezi lokumba olungenabumba nodaka endaweni yamanzi anosawoti. Uketshezi oluthile lokumba lusengakwazi ukumelana nosawoti, futhi izakhiwo ze-rheological azishintshi kakhulu. Ngaphansi kwe-4% yokuhlushwa kukasawoti kanye namanzi ahlanzekile, isilinganiso sokushintsha kwe-viscosity ye-CMC engazweli usawoti sikhuphuke saba ngaphezu kwe-1, okungukuthi, i-viscosity ayikwazi ukuguqulwa endaweni enosawoti omningi.
Udaka oluqukethe i-CMC lungalawula i-rheology yodaka.I-CMCayikwazi ukunciphisa ukulahlekelwa kwamanzi kuphela, kodwa futhi ikhulise i-viscosity.
1. Udaka oluqukethe i-CMC lungenza udonga lomthombo lube ikhekhe eliyisihlungi elincanyana, eliqinile nelincane, elinciphisa ukulahlekelwa kwamanzi. Ngemva kokwengeza i-CMC odakeni, umshini wokumba ungathola amandla okugunda okuqala aphansi, ukuze udaka lukhulule kalula igesi egoqwe kulo, futhi ngesikhathi esifanayo, imfucumfucu ingalahlwa ngokushesha emgodini wodaka.
2. Njengamanye ama-dispersions okumiswa, udaka lokumba luneshelufu elithile lokuphila. Ukwengeza i-CMC kungayenza izinze futhi kwelule impilo yeshalofu.
3. Udaka oluqukethe i-CMC aluvamile ukuthintwa isikhunta, futhi asikho isidingo sokugcina inani le-pH ephezulu kanye nokusebenzisa izivimbelakuvunda.
4. Udaka oluqukethe i-CMC lunozinzo oluhle futhi lunganciphisa ukulahlekelwa kwamanzi ngisho noma izinga lokushisa lingaphezu kwama-degree angu-150.
