Yawan Bentonite Slurry
1. Rarrabawa da Ayyukan slurry
1.1 Rarrabawa
Bentonite, wanda aka fi sani da dutsen bentonite, dutse ne mai yumɓu wanda ke ɗauke da babban kaso na montmorillonite, wanda galibi yana ɗauke da ƙaramin adadin illilite, kaolinite, zeolite, feldspar, calcite, da sauransu. Ana iya rarraba Bentonite zuwa nau'i uku: bentonite mai tushen sodium (ƙasar alkaline), bentonite mai tushen calcium (ƙasar alkaline) da ƙasa mai bleaching na halitta (ƙasar acidic). Daga cikinsu, ana iya rarraba bentonite mai tushen calcium zuwa bentonite mai tushen calcium-sodium da bentonite mai tushen calcium-magnesium, suma.
1.2 Aiki
1) Sifofin Jiki
Bentonite fari ne kuma rawaya ne mai haske a yanayi, yayin da yake bayyana a launin toka mai haske, ruwan hoda mai haske, ja mai launin ruwan kasa, baƙi, da sauransu. Bentonite ya bambanta a tauri saboda halayensa na zahiri.
2) Haɗin Sinadarai
Manyan sinadaran bentonite sune silicon dioxide (SiO2), aluminum oxide (Al2O3) da ruwa (H2O). A wasu lokutan ma sinadarin iron oxide da magnesium oxide yana da yawa, kuma calcium, sodium, da potassium galibi suna nan a cikin bentonite a cikin abubuwan da ke ciki daban-daban. Abubuwan da ke cikin Na2O da CaO a cikin bentonite suna da bambanci kan halayen jiki da sinadarai, har ma da fasahar sarrafawa.
3) Sifofin Jiki da Sinadarai
Bentonite ya yi fice a cikin ingantaccen hygroscopicity, wato faɗaɗawa bayan shan ruwa. Yawan faɗaɗawa da ya shafi shan ruwa ya kai har sau 30. Ana iya watsa shi a cikin ruwa don samar da wani abu mai kama da ruwa, mai kama da thixotropic, da kuma mai da shi mai kama da colloidal. Yana canzawa da mannewa bayan an gauraya shi da ƙananan tarkace kamar ruwa, slurry ko yashi. Yana iya shan iskar gas, ruwa, da abubuwa masu rai daban-daban, kuma matsakaicin ƙarfin sha zai iya kaiwa sau 5 na nauyinsa. Ƙasa mai yin bleaching mai aiki a saman acid na iya shanye abubuwa masu launi.
Sifofin jiki da sinadarai na bentonite sun dogara ne akan nau'in da abun da ke cikin montmorillonite da ke cikinsa. Gabaɗaya, bentonite mai tushen sodium yana da mafi kyawun halaye na zahiri da sinadarai da kuma aikin fasaha fiye da bentonite mai tushen calcium ko magnesium.

Yana da wuya a haƙa rami a cikin ramin sander, tsakuwa, layukan tsakuwa da wuraren da suka lalace don samun ƙananan halayen haɗin gwiwa tsakanin ƙwayoyin cuta. Mabuɗin matsalar yana cikin ƙara ƙarfin haɗin gwiwa tsakanin ƙwayoyin cuta, kuma yana ɗaukar slurry a matsayin shinge mai kariya a cikin irin wannan tsari.
3.1 Tasirin Yawan Slurry akan Saurin Hakowa
Gudun haƙowa yana raguwa yayin da yawan haƙori ke ƙaruwa. Gudun haƙowa yana raguwa sosai, musamman lokacin da yawan haƙori ya fi 1.06-1.10 g/cm3Da yawan danko na slurry, haka nan saurin haƙa ramin ke raguwa.
3.2 Tasirin Yashi a cikin Slurry akan haƙa rami
Abubuwan da ke cikin tarkacen duwatsu a cikin slurry suna haifar da haɗari yayin haƙa rami, wanda ke haifar da ramuka marasa kyau da aka tsaftace kuma daga baya ya makale. Bugu da ƙari, yana iya haifar da tsotsa da tashin hankali na matsi, wanda ke haifar da zubewa ko rugujewar rijiya. Yawan yashi yana da yawa kuma laka a cikin ramin yana da kauri. Yana sa bangon ramin ya ruguje saboda ruwa, kuma yana da sauƙi ya sa fatar laka ta faɗo ta haifar da haɗari a cikin ramin. A lokaci guda, yawan laka yana haifar da lalacewa sosai ga bututu, guntun haƙa rami, hannayen silinda na famfon ruwa, da sandunan piston, kuma tsawon lokacin aikinsu yana da gajere. Saboda haka, a ƙarƙashin manufar tabbatar da daidaiton matsin lamba na samuwar, ya kamata a rage yawan laka da yawan yashi gwargwadon iko.
3.3 Yawan Slurry a cikin Ƙasa Mai Taushi
A cikin laka mai laushi na ƙasa, idan yawan slurry ya yi ƙasa sosai ko kuma saurin haƙa ramin ya yi sauri sosai, zai haifar da rugujewar ramuka. Yawanci ya fi kyau a kiyaye yawan slurry a 1.25g/cm3a cikin wannan ƙasan ƙasa.
4. Tsarin Slurry na gama gari
Akwai nau'ikan slurry da yawa a fannin injiniyanci, amma ana iya rarraba su zuwa nau'ikan masu zuwa bisa ga sinadaran da ke cikinsu. Hanyar da ake bi wajen daidaita su ita ce kamar haka:

4.4 Ruwan Humic Acid
Humic acid slurry yana amfani da sinadarin alkali na kwal ko sodium humate a matsayin mai daidaita yanayi. Ana iya amfani da shi tare da sauran magungunan magani kamar Na-CMC. Tsarin da ake amfani da shi wajen shirya sinadarin humic acid slurry shine a ƙara sinadarin alkali na kwal 150-200kg (nauyin busasshe), Na2CO3 3-5kg, da ruwa 900-1000L a cikin 1m3 na sinadarin slurry: yawa 1.03-1.20 g/cm3, asarar ruwa 4-10ml/minti 30, pH 9.
