Ulwakhiwo olungoomatshini lodaka luye lwazanywa kwaye lwakhuthazwa iminyaka emininzi e-China, kodwa akukho nkqubela ibonakalayo yenziweyo. Ukongeza kokuthandabuza kwabantu malunga neenguqu zokubhukuqa eziya kuzisa ukwakhiwa koomatshini kwiindlela zokwakha zesintu, esona sizathu sikukuba phantsi kwemowudi yemveli, udaka oluxutywe kwisiza lunokubangela ukutsalwa kwemibhobho kunye nezinye iiprojekthi ngexesha lenkqubo yokwakha elungelelanisiweyo. kwiingxaki ezifana nobungakanani besuntswana kunye nokusebenza. Iimpazamo azichaphazeli nje kuphela inkqubela phambili yolwakhiwo, kodwa zikwanyusa ukuqina kolwakhiwo, nto leyo ezala uloyiko lwabasebenzi kubunzima kwaye yandisa ubunzima bokukhuthaza ukwakhiwa koomatshini.
Kwiminyaka yakutshanje, ngokusekwa kweefektri ezinkulu zodaka oluxutyiweyo kwilizwe lonke, umgangatho kunye nokuzinza kodaka kuye kwaqinisekiswa. Nangona kunjalo, udaka oluxubeneyo olomileyo luyalungiswa kwaye luveliswe yimizi-mveliso. Ngokubhekiselele kwizinto eziluhlaza kuphela, ixabiso kufuneka libe phezulu kunelo lokuxuba kwisiza. Ukuba utyabeko lwezandla luyaqhubeka, aluyi kuba nanzuzo yokukhuphisana phezu kodaka oluxutywayo kwisiza, nokuba kukho amazwe Ngenxa yomgaqo-nkqubo “wokuvalwa kwekheshi”, iifektri ezintsha zodaka ezixutyiweyo zisasokola ukufumana imali, kwaye ekugqibeleni. ubhanga.
Intshayelelo emfutshane ekusebenzeni okubanzi kodaka olutshizwe ngomatshini
Xa kuthelekiswa nodaka lwemveli oluxutywe kwisiza, owona mahluko mkhulu wodaka olutshiziweyo kumatshini kukuqaliswa kothotho lwemixube efana ne-hydroxypropyl methyl cellulose ether enokwandisa ukusebenza kodaka, ukuze ukusebenza kodaka oluxutyiweyo olusanda kuxutywa lulungile. . , izinga eliphezulu lokugcinwa kwamanzi, kwaye usenomsebenzi omhle wokusebenza emva komgama omde kunye nokumpompa okuphakamileyo. Inzuzo yayo enkulu ilele ekusebenzeni kwayo okuphezulu kunye nomgangatho olungileyo wodaka emva kokubumba. Ekubeni udaka lunomlinganiselo omkhulu wesantya sokuqala ngexesha lokutshiza, lunokuthi lubambe ngokuqinileyo kunye ne-substrate, enokunciphisa ngokufanelekileyo i-phenomenon ye-hollowing kunye nokuqhekeka. kwenzeke.
Emva kweemvavanyo eziqhubekayo, kufunyenwe ukuba xa ulungiselela udaka lokutyabeka ngomatshini, sebenzisa isanti eyenziwe ngumatshini kunye nobukhulu beqhekeza le-2.5mm, umxholo welitye ongaphantsi kwe-12%, kunye nokuhlelwa okufanelekileyo, okanye ubukhulu becala. ye-4.75mm kunye nesiqulatho sodaka esingaphantsi kwe-5%. Xa izinga lokugcinwa kwamanzi lodaka olutsha oluxutywe lulawulwa ngaphezu kwe-95%, ixabiso lokuhambelana lilawulwa malunga ne-90mm, kwaye ilahleko ye-2h ehambelanayo ilawulwa ngaphakathi kwe-10mm, udaka lunokusebenza kakuhle kokupompa kunye nokusebenza kokutshiza. ukusebenza, kunye nenkangeleko yodaka olubunjiweyo igudileyo kwaye icocekile, i-slurry ifana kwaye ityebile, akukho kuncipha, akukho mgodi kunye nokuqhekeka.
Ingxoxo ngezongezo eziDityanisiweyo zodaka olutshizwe ngumatshini
Inkqubo yokwakhiwa kodaka olutshiziwe ngomatshini ikakhulu ibandakanya ukuxuba, ukumpompa nokutshiza. Kwimeko yokuba ifomula ifanelekile kwaye umgangatho wezinto ezikrwada ufanelekile, owona msebenzi uphambili womatshini wokudibanisa udaka olutshiziweyo kukwandisa umgangatho wodaka olutsha oluxutywe kunye nokuphucula ukusebenza kokumpompa kodaka. Ke ngoko, umatshini ojikelezileyo otshizwe udaka lodaka lodibaniso lwenziwe ngearhente yokugcina amanzi kunye nearhente yokumpompa. I-Hydroxypropyl methylcellulose ether yinto egqwesileyo yokugcina amanzi, engakwazi ukunyusa kuphela i-viscosity ye-mortar, kodwa iphinde iphucule kakhulu i-fluidity of mortar kunye nokunciphisa ukuhlukana kunye nokuphuma kwegazi phantsi kwexabiso elifanayo lokuhambelana kwenzeka. I-arhente yokumpompa ngokuqhelekileyo iqulunqwe yi-arhente yokungenisa umoya kunye ne-arhente yokunciphisa amanzi. Ngethuba lenkqubo yokuvuselela i-mortar esanda kuxutywa, inani elikhulu leebhubhu zomoya ezincinci zingeniswa ukuba zenze impembelelo yebhola, enokunciphisa ukuxhathisa ukuxhatshazwa phakathi kweengqungquthela ezidibeneyo kunye nokuphucula ukusebenza kokupompa komdaka. . Ngexesha lenkqubo yokutshiza yodaka olufafaziwe ngomatshini, i-micro-vibration ebangelwa ukujikeleza kwepompo yokuhambisa i-screw iya kubangela ukuba udaka olukwi-hopper lube stratified, okukhokelela kwixabiso elincinci lokuhambelana kwinqanaba eliphezulu kunye nexabiso elikhulu lokuhambelana. kuluhlu olusezantsi, oluya kuba lula ukukhokelela ekuvalelekeni kombhobho xa umatshini usebenza, kwaye Emva kokubumba, umgangatho womdaka awufani kwaye ulungele ukomisa ukuncipha kunye nokuqhekeka. Ke ngoko, xa kuyilwa izongezo ezidityanisiweyo zodaka lokuqhushumba komatshini, ezinye izizinzi kufuneka zongezwe ngokufanelekileyo ukucothisa i-delamination yodaka.
Kuvavanyo lodaka olutshizwe ngoomatshini, idosi yesongezo esihlanganisiweyo yayiyi-0.08%. Udaka olufunyenweyo lunokusebenza kakuhle, ukusebenza kakuhle kokumpompa, akukho kuncipha ngexesha lenkqubo yokutshiza, kwaye ubukhulu becala lokutshiza bungafikelela kwi-25px.
