Zomwe zili mumatope mumchenga zimatha kuchepetsedwa powonjezera mchenga watsopano kapena kuchepetsa kuwonjezera kwa zida zothandizira. Kuipa kwa njira ziwirizi kudzafotokozedwa pamapeto pake.

5. Mapeto omaliza

1. Sinthani kuchuluka kwa zinthu zowonjezera mchenga

Makristali a bentonite awonongeka pamlingo winawake potenthetsera, ndipo mphamvu yolowa yonyowa imachepa mukawonjezera madzi ndikusakaniza. Pambuyo pakuwotcha kutentha kwambiri komanso nthawi yayitali, mawonekedwe a bentonite awonongeka kwathunthu, ndipo amakhala "dongo lakufa" lopanda mphamvu yolumikizana. Kuchuluka kwa kuponyera, kuchuluka kwa mchenga ndi chitsulo, kutentha kothira kwambiri komanso nthawi yayitali yozizira zonse zimakulitsa kuwonongeka kwa bentonite.

Njira yowongoka kwambiri yodziwira ngati ufa wamakala wabwino mumchenga wokulira ndikwanira ndikuwona kuyera kwa kuponyako komanso ngati mchenga wakakamira. Gawo la malasha mumchenga wakale limawotchedwa chifukwa cha kutentha kwazitsulo zosungunuka ndipo zimafunika kudzazidwanso. Kumbali inayi, zinthu zatsopano monga mchenga watsopano, mchenga wosakanikirana ndi bentonite amafunikiranso kuwonjezeredwa kuti akwaniritse bwino malasha ophulika. Chiwerengero chonse cha malasha ophulika omwe amawonjezedwa panthawi yosakanikirana ndi mchenga ndi kuchuluka kwa kuwonongeka kwa moto ndi zina zowonjezera zowonjezera. (Mphamvu yamalasha yothandiza ndiyofanana ndi zowonjezera zowonjezera m'malemba)

2. Kusintha kwa kukula kwa mchenga:

The tinthu kukula kwa paipi akamaumba mchenga zambiri 50/140, pamene tinthu kukula kwa utomoni mitima mchenga makamaka 50/100 kapena coarser. Kusakanikirana kwakukulu kwa mchenga wapakati kumakhudza kuzirala kwa mchenga wonse wakale, zomwe zidzawonjezera kuphulika kwa mchenga komanso kupindika pamwamba pake.

Pofuna kuti tinthu tating'onoting'ono tomwe tinkapanga mchenga kuti usakhale wolimba, tinthu tating'onoting'ono tomwe timachotsa fumbi titha kubwezeretsanso mumchenga wakale. Kapena onjezani mchenga watsopano wabwino kuti musinthe; monga tanenera ku maziko, pamene AFS yamchenga ikamafika pafupifupi 48, sintha mwa kupitiriza kuwonjezera mchenga watsopano 70/140 kapena 140/70; komabe, chifukwa choponyedwacho chaphwanyidwa pakatikati pa mchenga Kuchuluka kwa mchenga ndikokulira kale. Ngati tinthu tating'onoting'ono tomwe timapanga mchenga sakulowetsedwa mwamphamvu, sizikulimbikitsidwa kuti tiwonjezere mchenga watsopano mosalekeza, apo ayi zingakhudze ziwonetsero zina za magwiridwe antchito a mchenga (zokhutira ndi matope, kuchuluka kwake ndi mphamvu chifukwa cha kuchuluka kwatsopano kwa mchenga watsopano). kukhala ndi chikoka pa;  

3. Kusintha kwa matope

Kuwonjezeka kwa matope kumapangitsa kuti mchenga woumba kuchepa kuchepa, ndipo chodabwitsa cha "kuphulika kwa gasi" chidzachitika pakutsanulira, ndipo kuponyako kudzachotsedwa chifukwa cha kuphulika ndi mchenga womata. The matope zili dongosolo mchenga akamaumba sayenera kukhala okwera; matope omwe ali mumchenga amatha kuchepetsedwa pochepetsa kuchuluka kwa zida zothandizira, koma kuchepetsedwa kwa bentonite komweko kumapangitsa kuti mchenga woumba ukhale wotsika, komanso kuthekera kukweza ndi kukana mchenga kumachepa; Mlingo woyenera wa Kuchepetsa kumapangitsa kuti mchenga wodana ndi kukakamira kwa mchenga womwe ukuumba utsike.

Ngati muwonjezera kuchuluka kwa mchenga watsopano womwe ungasinthidwe kuti musinthe matopewo, choyamba muwerenge kuchuluka kwa zinthu zosiyanasiyana zomwe zangopangidwa kumene mumchenga, kenako mutha kuwerengera kuchuluka kwa mchenga wosaphika womwe ungapangidwe kuti matopewo akhale mchenga akamaumba kukumana ndondomeko ndondomeko.

Monga tanenera m'nkhaniyi, matope amatha kuchepetsedwa ndi 0.1% pa 30 kg iliyonse ya mchenga watsopano wowonjezeredwa; komabe, kuwonjezera kwambiri kwa mchenga watsopano sikungangowononga ndalama zokha, komanso kumachepetsa kuchuluka kwa mchenga womwe wagwiritsidwa ntchito mumchenga, womwe ungachepetse magwiridwe antchito amchenga. , The mchenga akamaumba diverges, zomwe zimakhudza luso mchenga akamaumba kuumba, ndi chodabwitsa mchenga kutsuka kumachitika pa ndondomeko kuponyera;

Chifukwa chake, wolemba amakhulupirira kuti ndiye chisankho chabwino kwambiri ngati matope omwe ali mumchenga atha kuwongoleredwa ndikusintha zida zochotsera fumbi.

Ponseponse, dongosolo lamchenga lokhazikika limatha kupanga ma castings apamwamba kwambiri. Kudzera lingaliro ili, tiyenera mosalekeza kusintha ndondomeko ya mchenga malinga ndi kusintha kwa zinthu kuti zikwaniritse zosowa za kupanga.
