I-Bentonite yokwaleka

I-Casting coating luhlobo lokugquma olufafazwe kudonga lwangaphakathi lwesikhunta kwinkqubo ephezulu yokuphosa, kwaye umsebenzi wayo kukwenza ukugqitywa komphezulu wokuphosa okulungileyo, ngelixa ugwema into ebambekayo phakathi kwendawo yokusebenza kunye nokubumba.Kukulungele ukuba i-workpiece isuswe kwi-mold.Ukwaleka kufumaneka kwi-liquid okanye kwifom yomgubo.

Iithegi zeMveliso

Iimpawu ze-bentonite zokugqoka iingubo

1. Ukusebenza kakuhle kokumiswa, kwiingubo zokuphosa, umsebenzi oyintloko we-bentonite ukumiswa, okunokwenza iimpawu ze-casting coating ngokwayo.Ngale ndlela, ukugqitywa komphezulu womsebenzi wokuphosa unokuqinisekiswa.

2. Ukumelana nobushushu obuphezulu obunamandla, kwinkqubo yokuphosa, iqondo lokushisa lenxalenye ekudibaneni nolwelo lwetsimbi ngokubanzi lifikelela kwi-1200 degrees Celsius, kwaye ukugquma kokuphosa kule ndawo kufuneka kukwazi ukumelana novavanyo lobushushu obuphezulu.

3. I-fineness enhle, ngokuqhelekileyo isetyenziselwa ukwenza iingubo zokuphosa i-bentonite, iimfuno zayo ze-fineness ubuncinane ze-325 mesh okanye ngaphezulu.Ezinye iimveliso eziphezulu zifuna amawaka wamehlo.

4. Ukucoceka okuphezulu, ngokuqhelekileyo kusetyenziselwa ukwenza iingubo zokulahla i-bentonite kufuna ukucoceka okuphezulu, okungavunyelwe ukuba nokungcola okuninzi.Oku kulungele ukuchaphazela umgangatho womsebenzi owenziweyo ngenxa yokungcola okugqithisileyo kwinkqubo yokuphosa.

Ngamafutshane, i-bentonite ye-foundry coating bentonite iphezulu kakhulu kuneemveliso eziqhelekileyo.Kwimveliso yangempela, kukho i-bentonite esekelwe kwi-sodium ephezulu kunye nococeko oluphezulu kunye ne-lithium-based bentonite ebiza kakhulu.Kungakhathaliseki ukuba yeyiphi imveliso, inani le-bentonite elisetyenziswe leli shishini lincinci kakhulu.

ukusebenza kwe-coating bentonite

1. Ukuphucula ukumiswa kunye ne-thixotropy yengubo, kwaye ukwandise ixesha lokugcinwa kwengubo;
2. Ukuphucula amandla okufihla, i-brushability kunye ne-flatness yengubo;
3. Ukuphucula i-refractory degree kunye nokuchasana kwamanzi kwengubo kunye nokubambelela kunye nokunyathela kwengubo yokugqoka;
4. I-Bentonite inokutshintsha i-powder enzima ye-calcium kunye nokunciphisa iindleko zokuvelisa i-coating;
5. Ukuphucula ukuxhathisa ukushisa okuphantsi kwengubo.

Ukusebenzisa i-bentonite yokugqoka

I-Bentonite inokusebenza njenge-dispersant kunye ne-thickener kwiingubo.Ukongezelela, iphinda idlale indima ethile ekunamatheleni kwengubo, amandla angangeni manzi, ukumelana nokushisa okuphezulu kunye nokuphantsi, ukugudisa, njl.Ngophuhliso lwesayensi kunye nobuchwepheshe, i-bentonite yokugqoka iya kusetyenziswa ngokubanzi.

Indlela yokukhetha ipeyinti ye-bentonite

Ukukhethwa kwengubo ye-bentonite kukuthobela ingqalelo kwiiparitha ezininzi zimhlophe, ukulunga, amaxesha okwandisa.I-Bentonite yeengubo ezihlangabezana nale miqathango inokuhlangabezana neemfuno ezisisiseko zokugqoka ngexesha lokusetyenziswa.Kunconywa ukuba usebenzise umhlaba we-ace paint bentonite, onomgangatho obalaseleyo kunye nexabiso elifanelekileyo
