Ntchito yomanga matope yakhala ikuyesedwa ndikulimbikitsidwa kwa zaka zambiri ku China, koma palibe kupita patsogolo kwakukulu komwe kwachitika. Kuphatikiza pa kukayikira kwa anthu za kusintha kwachiwembu komwe kumangirira kumadzetsa njira zomanga zamakina, chifukwa chachikulu ndi chakuti pansi pa chikhalidwe chachikhalidwe, matope osakanizidwa pamalowa angayambitse kutsekera kwa chitoliro ndi ntchito zina panthawi yomanga makina. ku zovuta monga kukula kwa tinthu ndi magwiridwe antchito. Zolakwika sizimangokhudza momwe ntchito yomanga ikuyendera, komanso imawonjezera mphamvu yomanga, yomwe imapangitsa kuti ogwira ntchito aziopa zovuta komanso kumawonjezera vuto lolimbikitsa zomangamanga zamakina.
M’zaka zaposachedwapa, ndi kukhazikitsidwa kwa mafakitale aakulu a matope osakaniza owuma m’dziko lonselo, ubwino ndi kukhazikika kwa matope zatsimikiziridwa. Komabe, matope osakanizika owuma amakonzedwa ndikupangidwa ndi mafakitale. Pankhani ya zopangira zokha, mtengo uyenera kukhala wapamwamba kuposa wa kusakaniza komwe kuli pamalopo. Ngati kupaka pulasitala pamanja kupitilizidwa, sikukhala ndi mwayi wopikisana nawo pakusakaniza matope pamalopo, ngakhale pali mayiko Chifukwa cha "kuletsa ndalama", mafakitale atsopano osakaniza matope akuvutikirabe kuti apeze zofunika pamoyo, ndipo pamapeto pake. kusowa ndalama.
Chidule chachidule cha magwiridwe antchito a makina opopera matope
Poyerekeza ndi chikhalidwe matope osakaniza pa malo, kusiyana kwakukulu kwa makina opopera matope ndi kuyambitsa mndandanda wa admixtures monga hydroxypropyl methyl cellulose ether kuti akhoza kukhathamiritsa ntchito ya matope, kotero kuti workability wa matope atsopano osakaniza ndi zabwino. . , kuchuluka kwa madzi osungira madzi, ndipo akadali ndi ntchito yabwino yogwira ntchito pambuyo popopa mtunda wautali komanso wautali. Ubwino wake waukulu wagona pakumanga bwino kwake komanso mtundu wabwino wamatope pambuyo pakuwumba. Popeza matope amakhala ndi liwiro lalikulu poyambira kupopera mbewu mankhwalawa, amatha kugwira mwamphamvu ndi gawo lapansi, zomwe zimatha kuchepetsa kuphulika ndi kusweka. kuchitika.
Pambuyo mayesero mosalekeza, anapeza kuti pokonzekera makina-spraying pulasitala matope ntchito makina opangidwa mchenga ndi pazipita tinthu kukula 2.5mm, mwala ufa zili zosakwana 12%, ndi wololera gradation, kapena pazipita tinthu kukula. 4.75mm ndi matope osakwana 5%. Pamene madzi osungira madzi a matope osakanikirana amawongoleredwa pamwamba pa 95%, mtengo wosasinthasintha umayendetsedwa pafupifupi 90mm, ndipo kutayika kosasinthasintha kwa 2h kumayendetsedwa mkati mwa 10mm, matope amakhala ndi ntchito yabwino yopopera ndi kupopera mbewu mankhwalawa. ntchito, ndi maonekedwe a matope opangidwa ndi osalala ndi oyera, slurry ndi yunifolomu ndi wolemera, palibe kugwa, palibe dzenje ndi ming'alu.
Zokambirana pa Zowonjezera Zophatikizika za Tondo Wopopera Pa makina
Ntchito yomanga makina opopera matope makamaka imaphatikizapo kusakaniza, kupopera ndi kupopera mbewu mankhwalawa. Poganizira kuti chilinganizocho ndi chololera komanso mtundu wa zida zopangira ndizoyenerera, ntchito yayikulu ya makina opopera matope ophatikizira owonjezera ndikukulitsa mtundu wa matope osakanikirana ndikuwongolera magwiridwe antchito amatope. Choncho, makina ambiri opopera matope pawiri zowonjezera amapangidwa ndi wothandizila madzi posungira ndi kupopera wothandizira. Hydroxypropyl methylcellulose ether ndi wabwino kwambiri kusunga madzi wothandizila, amene sangakhoze kuwonjezera mamasukidwe akayendedwe a matope, komanso kwambiri kusintha fluidity wa matope ndi kuchepetsa tsankho ndi magazi pansi kugwirizana kugwirizana mtengo chinachitika. Makina opopa nthawi zambiri amakhala ndi mpweya wophunzitsira komanso wochepetsera madzi. Panthawi yotsitsimula ya matope osakanikirana, tinthu tating'ono tating'ono tating'ono tating'ono timayambitsidwa kuti tipange mpira, womwe ungathe kuchepetsa kukana kukangana pakati pa tinthu tating'onoting'ono ndikuwongolera magwiridwe antchito amatope. . Pakupopera mbewu mankhwalawa matope opopera makina, kugwedezeka kwapang'onopang'ono komwe kumachitika chifukwa cha kuzungulira kwa mpope wotumizira wononga kumapangitsa kuti matope omwe ali mu hopper asunthidwe, zomwe zimapangitsa kuti pakhale kusanja pang'ono kumtunda ndi mtengo waukulu. m'munsi wosanjikiza, zomwe zidzatsogolera mosavuta kutsekeka kwa chitoliro pamene makina akugwira ntchito, ndipo Pambuyo pa kuumba, khalidwe la matope silili yunifolomu ndipo limakonda kuyanika shrinkage ndi kuwonongeka. Chifukwa chake, popanga zowonjezera zopangira matope ophulika pamakina, zokhazikika zina ziyenera kuwonjezeredwa kuti zichepetse kuchepa kwa matope.
Pakuyesa kwamatope opopera pamakina, mlingo wa zowonjezerazo zinali 0.08%. Mtondo wotsatirawo unali ndi ntchito yabwino, kupopera bwino kwambiri, osagwedezeka panthawi yopopera mankhwala, ndipo makulidwe apamwamba a kupopera mankhwala amodzi amatha kufika 25px.
