I-bentonite esekwe kwi-sodium yokuphosa

I-Bentonite ngudongwe okhethekileyo wamaminerali kunye ne-viscosity, ukwanda, i-lubricity, ukufunxa kwamanzi kunye ne-thixotropy kunye nezinye iimpawu, ukusetyenziswa kugubungele izinto zokuphosa, iipellet zetsimbi, iikhemikhali zokugquma, ukubhobhoza udaka kunye noshishino olulula kunye nezolimo kwiinkalo ezahlukeneyo, kamva ngenxa yobubanzi bayo. ukusetyenziswa, eyaziwa ngokuba "umhlaba jikelele", eli phepha lixoxa kakhulu ngokusetyenziswa kunye nendima ye-bentonite ekubunjweni.

Ukubunjwa kwesakhiwo se-bentonite
I-Bentonite iqulethwe yi-montmorillonite ngokwesakhiwo sayo se-crystal, kuba i-crystal yayo ekhethekileyo inokubambelela ngokuqinileyo emva kokuxutywa kwamanzi, ngoko isetyenziselwa ngokubanzi kwintlabathi yokuphosa, isanti ihlanganiswe ndawonye ukuze yenze amandla amanzi kunye neplastiki, kunye namandla omileyo emva kokumisa.Emva kokuba i-bentonite isomile, ukubumbana kwayo kunokubuyiselwa emva kokungeza amanzi.

Ukusetyenziswa kwe-bentonite kwi-casting

Umgangatho we-bentonite ubaluleke kakhulu kwimveliso ye-castings kwi-casting, kwaye umgangatho we-bentonite unempembelelo esondeleyo kumphezulu kunye nomgangatho wangaphakathi wokuphosa.Ukusetyenziswa kwe-bentonite ekumgangatho ophezulu kwimisebenzi yokuphosa kuya kwandisa kakhulu amandla, ukuqina kunye nokunyanzeliswa komoya, ukunciphisa umthamo wamanzi wesanti yokubumba, ukuphucula ngokufanelekileyo ukugqitywa komphezulu kunye nokuchaneka kwe-castings, kunye nokusombulula iingxaki zomgangatho oqhelekileyo phezu komhlaba. ukubunjwa kwesanti, okufana nokuhlanjwa kwesanti, ukufakwa kwesanti, umngxuma wesanti, isanti encangathi, imingxuma, imingxuma edilikayo kunye nothotho lweziphene.Kuphuhliso lwanamhlanje olukhawulezayo lwemizi-mveliso, i-bentonite njengolungiselelo lodongwe lokubumba isanti iseyeyona nto ikhethwayo yokubumba kushishino lokugalela.

I-Bentonite ineemfuno zokusebenza kwezoshishino zokuphosa
I-viscosity adhesion ye-bentonite iyisitshixo sokulinganisa umgangatho we-bentonite yokuphosa, efuna ukucoceka okuphezulu kwe-montmorillonite, ubukhulu be-particle (95% ngokusebenzisa i-200 mesh sieve), kunye nenkqubo yokulungisa i-sodium, ukwenzela ukuba inani elincinci lesanti yokubumba. inokufumana amandla oxinzelelo aphezulu omanzi.

Indima ye-bentonite ekujuleni

(1) Isetyenziswa njengesibophelelo sokubumba sesanti
I-Bentonite ine-viscosity enkulu kakhulu, i-plasticity ephezulu, amandla amahle, ixabiso eliphantsi, kwaye inokwenza isanti yokubumba i-casting ifakwe ngokukhawuleza.

(2) Ukwandisa iplastiki yokuphosa
Isetyenziswe njenge-binder ye-sand binder material, i-bentonite inokuphucula i-plasticity ye-castings, kwaye inokuthintela ngokufanelekileyo iziphene zemveliso ye-castings, ezifana: inokuthintela ukufakwa kwesanti, i-scarring, i-lump dropping, ukuwa kwesanti.

(3) Ukusetyenziswa kwakhona okulungileyo kunye neendleko eziphantsi
Ekukhethweni kweemodeli, sincoma ukusetyenziswa kwe-bentonite eyenziwe nge-sodium esekelwe kwi-sodium, kuba izikhombisi ze-sodium-based bentonite zinamandla kakhulu kune-bentonite esekelwe kwi-calcium, njengale: ukumelana nokushisa kunye nokuzinza ngenxa ye-bentonite esekelwe kwi-calcium.Ngoko ke, nasemva kokuba ingxowa ye-sodium bentonite ipholile ngokupheleleyo kwaye yomiswe kwiqondo lokushisa eliphezulu, isenamandla okubambelela okuqinileyo xa amanzi eyongezwa okwesibini, kwaye isenokuqhubeka isetyenziswa njenge-binder yesanti yokubumba. ngenxa yokusetyenziswa kwakhona okunamandla kunye neendleko eziphantsi, ngoko i-sodium bentonite ikhethwa kuqala njengento ekhethiweyo kwinkqubo yokuphosa.

(4) Ithamo lincinci, kwaye amandla okuphosa aphezulu
I-Bentonite ine-adhesion eqinile kunye ne-dosage encinci, yongeza i-5% ye-sodium-based bentonite ephezulu kwisanti yokuphosa inokunciphisa kakhulu umxholo wodaka lwesanti ephosayo, ngakumbi amathuba okuba izinto zokufunxa amanzi, umlotha kunye ne-porosity kwisanti yokubumba iya kuba. kuncitshiswe ngokufanelekileyo, kwaye amandla okuphosa aya kwandiswa kakhulu.

(5) Ukuphucula imveliso kunye neenzuzo zoqoqosho zamashishini asisiseko
Xa usebenzisa i-bentonite ephezulu yokuvelisa i-castings, umxholo osebenzayo we-bentonite we-5% ~ 6% kwisanti endala yanele, kwaye i-1% ~ 2% inokudibaniswa rhoqo xa ixutywa.Itoni nganye ye-bentonite ephezulu inokuvelisa i-10 ~ 15 t castings kumgca wokuvelisa oomatshini.
Ewe, isicelo kunye nendima ye-bentonite ekukhupheni konke kufakwe apha, ndiyathemba ukuba unokubhekisela kuyo xa uqonda i-bentonite, i-multi-purpose non-metallic mineral clay, ekufundeni okunzulu.
