Umthengisi wenhlabathi we-Foundry bentonite
Ukusakaza i-bentonite esekelwe kwi-sodiumiyisibopho esidingekayo sokubumba isikhunta sesihlabathi, futhi ukukhethwa kwe-bentonite efanelekile ngokusho kwekhwalithi yokukhipha akukwazi kuphela ukuqinisekisa ikhwalithi, kodwa futhi kunciphise izindleko.Ngakho-ke, ukukhetha i-bentonite efanele ngokuya ngekhwalithi yokubunjwa yiyona nto ehamba phambili yomsebenzi wesikhunta sesihlabathi.
Izimpawu nezici:
Lo mkhiqizo uyimpushana emhlophe noma ephuzi ekhanyayo, impushana ebomvu yomhlaba.
Isigaba somkhiqizo:
(1) Izinga le-sodium: lingele-high-thermal stability casting ne-sodium-based bentonite, lo mkhiqizo ulungele ukukhishwa okunemba okuphezulu,ukulingisa ngokunemba, ngokufaka okuncane (ngaphansi kuka-5%), ukucindezela okumanzi, amandla aphezulu okushisa nokushisa okumanzi, ukungena komoya, ukusebenza okuhle kokusetshenziswa kabusha, kuyadingeka ekusakazeni okunembayo okuphezulu, abakhiqizi bokusakaza ngokunemba.
(2) Izinga lesibili le-sodium: lingele-bentonite ejwayelekile esekelwe ku-sodium, lo mkhiqizo ulungele ukubunjwa okunembayo, ukulingisa okuvamile, okokufaka okumaphakathi (5-8%), ukungena komoya, ukusebenziseka kabusha okuhle, ukukhetha okuyinhloko kokusakazwa okunembayo. , abakhiqizi abajwayelekile be-casting.is umkhiqizo uyimpushana ephuzi emhlophe noma ekhanyayo, impushana ebomvu yomhlaba.
3) I-calcium-based: Ingowe-bentonite ejwayelekile esekelwe ku-calcium, lo mkhiqizo ulungele ukulingwa okuvamile, ukulingwa okungekuhle, futhi ungumkhiqizo okhethwayo wokulingisa ama-rough.
Ukupakisha nokugcina:
Kusetshenziswa ifilimu yepulasitiki yangaphakathi, isikhwama esilukiwe sangaphandle sipakishwa ngezingqimba ezimbili noma sipakishwe ngokwezidingo zomsebenzisi, kanti isisindo sokupakisha singu-400.25kg, 500.25kg, 10001.0kg.

Okuqukethwe okuphezulu kwe-sodium, i-viscosity ephezulu, i-adsorption enamandla, ubumba lwensipho olusekelwe kwi-sodium
Amaminerali angewona awensimbi ane-montmorillonite njengokwakheka kwamaminerali okuyinhloko.
I-Bentonite iyi-mineral engeyona eyensimbi ene-montmorillonite njengengxenye yamaminerali eyinhloko, isakhiwo se-montmorillonite sakhiwe nge-silicon-oksijini tetrahedron ehlanganiswe nongqimba lwe-aluminium oksijini octahedron olwakhiwe 2:1 isakhiwo sekristalu, ngenxa yesakhiwo esinezingqimba esakhiwe iyunithi ye-montmorillonite. amaseli Kunama-cation athile, njenge-Cu, Mg, Na, K, njll., futhi lawa maseli eyunithi namayunithi e-montmorillonite awazinzile, kulula ukushintshaniswa ngamanye ama-cation, ngakho anokushintshana okungcono kwe-ion.Amazwe angaphandle asetshenziswe eminyangweni engaphezu kwe-100 emikhakheni ye-24 yokukhiqiza izimboni nezolimo, enemikhiqizo engaphezu kuka-300, ngakho abantu bayibiza ngokuthi "umhlabathi wendawo yonke".

Abakhiqizi be-wholesale kasawoti ukumelana nepayipi lokumba i-bentonite
I-Trenchless empeleni iyindlela yokwakha kubunjiniyela bansuku zonke, njengokwakhiwa kokumba okuvundlile, ukwakhiwa kwe-jacking yamapayipi, ukumba uwoyela, ukuhlola i-geological kanye nokwakhiwa komshini wesihlangu somhubhe.Amaphrojekthi angawenzi umsebenzi wokwakha ngaphansi komhlaba ngokumba umhlabathi abizwa ngokuthi ama-trenchless project.Kumaphrojekthi angenawo amanzi, i-trenchless bentonite idlala indima ebalulekile.

Ukuqina kwe-bentonite ngokumba okungenantambo kwe-sodium-based calcium based piling
I-bentonite yodaka iyinsimbi yobumba enamanzi ene-montmorillonite njengengxenye eyinhloko, isetshenziswa ngokuyinhloko njengezinto zokumba izinto zokudonsa ebunjiniyela obuyisisekelo, esetshenziselwa ukwenza udaka lokumba, iningi lokusetshenziswa kwemodeli ye-bentonite yodaka yi-bentonite esekelwe kwi-sodium.

I-bentonite esekelwe ku-sodium esekelwe ku-calcium ye-rubber
Ama-reagents asetshenziselwa ukuvimbela ngempumelelo ukunamathela kwefilimu.
Inhlanganisela ye-organic ye-rubber isolate, okuphuma ku-stearic acid, ama-anti-sticking agents akhethekile, ama-surfactants akhethekile, ama-ultrafine powders nezinye izinto.

I-bentonite ekhethekile ye-gel ephilayo yokumba uketshezi
I-Bentonite iwuhlobo lobumba oluphethwe i-montmorillonite.I-Montmorillonite iyiminerali ye-silicate enezingqimba ehlanganiswe izendlalelo ezimbili ze-Si-O tetrahedron enongqimba lwe-Al-(O,OH) octahedral njengeyunithi yesakhiwo.

I-Metallurgical pellet bentonite
I-Metallurgical pellet bentonite iyi-iron ore pellet binder ene-adhesion eqinile kanye nokuzinza okuphezulu kwezinga lokushisa.
I-Bentonite yama-pellets e-metallurgical i-iron ore pellet binder.Ngenxa yokunamathela kwayo okuqinile nokuqina kokushisa okuphezulu, i-bentonite esekelwe kwi-sodium yengezwa ku-iron concentrate powder ne-1-2% ye-sodium-based bentonite, eyomiswa ngemva kwe-granulation futhi yakhelwe ama-pellets, okwenza ngcono kakhulu amandla okukhiqiza ama-blast furnaces futhi iye yasetshenziswa kakhulu izigayo zensimbi.

I-bentonite esekwe ku-sodium yokusakaza
I-Bentonite iyibumba elikhethekile lamaminerali eline-viscosity, ukunwetshwa, i-lubricity, ukumuncwa kwamanzi kanye ne-thixotropy nezinye izici, ukusetshenziswa kuye kwahlanganisa izinto zokuphonsa, ama-pellets e-metallurgical, ama-chemical coatings, imboni yokumba udaka kanye nokukhanya kanye nezolimo emikhakheni ehlukahlukene, kamuva ngenxa yobubanzi bayo. ukusetshenziswa, okwaziwa ngokuthi "inhlabathi yendawo yonke", leli phepha lixoxa ngokuyinhloko ngokusetshenziswa kanye nendima ye-bentonite ekubunjweni.
Ukwakheka kwesakhiwo se-bentonite
I-Bentonite yenziwe nge-montmorillonite ngokusho kwesakhiwo sayo se-crystal, ngoba i-crystal yayo eyingqayizivele inokunamathela okuqinile ngemva kokumuncwa kwamanzi, ngakho-ke isetshenziswa kabanzi ekukhipheni isihlabathi, isihlabathi sihlanganiswe ndawonye ukuze senze amandla amanzi kanye ne-plasticity, namandla omile ngemva kokumisa.Ngemuva kokuthi i-bentonite isomile, ukuhlangana kwayo kungabuyiselwa ngemva kokwengeza amanzi. -
I-Bentonite engangeni manzi futhi ingavuzi
I-Bentonite engangeni manzi futhi i-anti-seepage iyinto efanelekile engangeni manzi futhi engenamanzi eyenziwe ngokusebenzisa i-bentonite, insiza yamaminerali engavamile engeyona eyensimbi e-China, njengento eyinhloko eluhlaza, futhi ihlanjululwe futhi icutshungulwe izinqubo zokukhiqiza ezikhethekile ezifana nokucubungula amaminerali, i-sodification, ukomisa nokugaya.Ukubukeka kuyimpushana empunga-emhlophe noma ephuzi, esetshenziswa kakhulu njengezinto ezingangeni manzi nezingangenisi ezisekelweni zobunjiniyela ezihlukahlukene.Uma kuqhathaniswa nemikhiqizo efanayo, i-bentonite yokuvimbela amanzi kanye nokugeleza kwamanzi inezici zokumuncwa okuhle kwamanzi, izinga eliphezulu lokunwetshwa kanye nomphumela oqinile wokufakwa kwamanzi, futhi iwumkhiqizo omusha wezinto ezingangeni manzi onokusebenza okuhle kokuvimbela ukuvuza kanye nenani eliphansi.
