Imithombo kadaka ihlukile, futhi izingxenye zazo zihlukile. Udaka esihlabathini lukakhonkolo kanye ne-gravel lihlukaniswe izigaba ezintathu: i-limestone powder, ubumba, ne-calcium carbonate. Phakathi kwazo, i-Stone Powder iyizinhlayiya ezinhle esihlabathini esenziwe ngosayizi wezinhlayiyana ezingaphansi kwama-75 μm. Kuyinto yamadwala abazali afanayo njengesihlabathi esenziwe futhi anesakhiwo esifanayo samaminerali. Ingxenye eyinhloko yi-CACO3, okuyingxenye yokwakheka kweziqu kwesihlabathi esenziwe.
.
Ngokuvamile kuzwakala ukuthi isizathu esiyinhloko esenza ukuthi i-powder yodaka ithinta ukhonkolo exutshwe ne-lignosulfonate kanye nama-naphthalene-based When Agents Agents ngumncintiswano we-adsorption phakathi kodaka nosimende. Ayikho incazelo enobunye emgabeni osebenzayo we-mud powder kanye ne-polycarboxyylic acid amanzi ancishisiwe ament. Ezinye izazi zikholelwa ukuthi umgomo osebenzayo we-powder kadaka kanye ne-ejenti enciphisa amanzi kuyafana nalokho kukakhonkolo. I-ejenti enciphisa amanzi i-adsorbed ebusweni bamakhabe noma i-powder kadaka enamaqembu e-anionic. Umehluko ukuthi inani kanye nenani le-adsorption ye-ejenti encishisiwe yamanzi nge-mud powder inkulu kakhulu kunaleyo kasimende. Ngasikhathi sinye, indawo ekhethekile ephezulu yokwakheka kwamaminerali wobumba futhi imunca amanzi amaningi futhi inciphise amanzi amahhala ku-slurry, okuthinta ngqo ukusebenza kokhonkolo.
(2) Imiphumela yamaminerali ahlukene ekwenzeni ama-ejenti anciphisa amanzi:
Ucwaningo lukhombisa ukuthi udaka olungama-clayey kuphela olunokunwetshwa okubalulekile kanye nokutholwa kwamanzi kuzoba nomthelela obalulekile ekusebenzeni okusebenzayo kanye nezindawo ezenziwa kamuva zokhonkolo. Udaka olujwayelekile lobumba oluhlanganisiwe luhlanganisa i-kaolin, engekho kanye ne-montmorillonite. Uhlobo olufanayo lommeli oncishisiwe lwamanzi lunezinzwa ezihlukile zokudonswa kwama-powders anezimbiwa ezihlukene, futhi lo mehluko ubaluleke kakhulu ekukhetheni ama-ejenti ancishiswe amanzi kanye nokuthuthukiswa kwama-ejenti alwa namanzi.
(3) Umphumela wokuqukethwe kwe-powder ye-mud ezizakhiweni zokhonkolo:
Ukusebenza okusebenzayo kukakhonkolo kungakuthinta kuphela ukwakhiwa kokhonkolo, kodwa futhi kuthinta izakhiwo zakamuva ezenziwe ngokhonkolo nokuqina kokhonkolo. Ivolumu yezinhlayiya ze-powder zodaka ayizinzile, zincipha lapho yomile futhi iyanda lapho imanzi. Njengoba okuqukethwe kwe-MUD kukhuphuka, noma ngabe kungumenzeli wamanzi oncishisiwe wamanzi noma i-ejenti ye-naphthalene-based agent, kuzonciphisa isilinganiso esincishisiwe samanzi, amandla, kanye nokwehla kokhonkolo. Ukuwa, njll., Letha ukulimala okukhulu kokhonkolo. Isihlabathi Esijwayelekile Sikazwelonke "Isihlabathi Sokwakha" (GB / T14684-2011) Lapho Ibanga Lakhonkolo Lisebangeni lika-C30 noma kukhona ukumelana nesithwathwa, okuqukethwe okukhethekile, okuqukethwe okukhethekile kwe-mud, okuqukethwe kwe-mud powder esihlabathini ngeke kudlule u-3.0 %, kanye nokuqukethwe kwe-mud inqwaba ngeke kudlule i-1.0%; Lapho iBanga lamakhonkrithi lingaphansi kuka-C30, okuqukethwe kwe-powder mud ngeke kwedlule ku-5.0% kanye nokuqukethwe kwe-mud block ngeke kudlule i-2.0%.
