Ukwakhiwa kodaka ngemishini kuzanywe futhi kwakhuthazwa iminyaka eminingi eShayina, kodwa ayikho inqubekelaphambili enkulu esele yenziwe. Ngaphezu kokungabaza kwabantu mayelana nezinguquko zokuketula ezizolethwa ukwakhiwa kwemishini ezindleleni zendabuko zokwakha, isizathu esiyinhloko siwukuthi ngaphansi kwemodi evamile, udaka oluxutshwe esizeni kungenzeka lubangele ukuxhunywa kwamapayipi kanye neminye imiklamo ngesikhathi senqubo yokwakha imishini ezinkingeni ezinjengosayizi wezinhlayiyana nokusebenza. Amaphutha awathinti nje kuphela inqubekelaphambili yokwakha, kodwa futhi andisa umfutho wokwakha, okwenza abasebenzi besabe ubunzima futhi andise nobunzima bokukhuthaza ukwakhiwa kwemishini.
Eminyakeni yakamuva, ngokusungulwa kwezimboni ezinkulu zodaka oluxutshwe okomile ezweni lonke, ikhwalithi kanye nokuzinza kwedaka sekuqinisekisiwe. Nokho, udaka oluxutshwe okomile luyacutshungulwa futhi lukhiqizwe amafekthri. Mayelana nezinto zokusetshenziswa kuphela, intengo kufanele ibe phezulu kunaleyo yokuxuba endaweni. Uma kuqhubeka ukuplasta ngezandla, ngeke kube nokuncintisana ngaphezu kodaka oluxutshwa endaweni, ngisho noma ekhona amazwe Ngenxa yenqubomgomo “yokuvinjelwa kwemali”, izimboni ezintsha zodaka ezixutshwe okomile zisazabalaza ukuze ziziphilise, futhi ekugcineni. shona phansi.
Isingeniso esifushane ekusebenzeni okuphelele kodaka olufuthwe ngomshini
Uma kuqhathaniswa nodaka lwendabuko oluxutshwe esizeni, umehluko omkhulu kakhulu wodaka olufuthwe ngomshini ukwethulwa kochungechunge lwezingxube ezifana ne-hydroxypropyl methyl cellulose ether ezingathuthukisa ukusebenza kodaka, ukuze ukusebenza kodaka olusanda kuxutshwa kube kuhle. . , izinga eliphezulu lokugcinwa kwamanzi, futhi kusenokusebenza okuhle kokusebenza ngemva kokumpompa ibanga elide nokuphakama okuphezulu. Inzuzo yayo enkulu itholakala ekusebenzeni kahle kwayo okuphezulu kanye nekhwalithi enhle yodaka ngemuva kokubunjwa. Njengoba udaka lunesivinini esikhulu sokuqala ngesikhathi sokufafaza, lungaba nokubambelela ngokuqinile ku-substrate, okunganciphisa ngempumelelo isenzakalo sokubhoboza nokuqhekeka. zenzeka.
Ngemva kokuhlolwa okuqhubekayo, kutholakala ukuthi lapho ulungiselela udaka lokunameka olufafazwe ngomshini, sebenzisa isihlabathi esenziwe ngomshini esinobukhulu bezinhlayiyana ezingaba ngu-2.5mm, impushana yetshe engaphansi kuka-12%, nokuhlukaniswa okunengqondo, noma ubukhulu bezinhlayiyana. engu-4.75mm kanye nodaka olungaphansi kuka-5%. Uma izinga lokugcinwa kwamanzi lodaka olusanda kuxutshwa lilawulwa ngaphezu kuka-95%, inani lokuvumelana lilawulwa cishe ku-90mm, futhi ukulahlekelwa okungaguquki kwe-2h kulawulwa ngaphakathi kuka-10mm, udaka lusebenza kahle ukumpompa nokusebenza kokufafaza. ukusebenza, futhi ukubonakala kodaka olwakhiwe kubushelelezi futhi kuhlanzekile, i-slurry ifana futhi icebile, akukho ukugoqa, akukho umgodi nokuqhekeka.
Ingxoxo Ngezithako Ezihlanganisiwe Zodaka Olufuthwe Ngomshini
Inqubo yokwakha udaka olufuthwe ngomshini ikakhulukazi ihlanganisa ukuxuba, ukupompa kanye nokufutha. Ngokwesisekelo sokuthi ifomula inengqondo futhi ikhwalithi yezinto ezingavuthiwe ifanelekile, umsebenzi oyinhloko wesengezo senhlanganisela yodaka olufuthwe umshini uwukwenza ngcono ikhwalithi yodaka olusanda kuxutshwa futhi kuthuthukiswe ukusebenza kokupompa kodaka. Ngakho-ke, isithasiselo senhlanganisela yodaka esifuthwe ngomshini jikelele sakhiwe i-ejenti yokugcina amanzi kanye ne-ejenti yokupompa. I-Hydroxypropyl methylcellulose ether iyi-ejenti enhle kakhulu yokugcina amanzi, engakwazi nje ukwandisa i-viscosity yodaka, kodwa futhi ithuthukise kakhulu uketshezi lodaka futhi inciphise ukuhlukaniswa nokopha ngaphansi kwenani elifanayo lokuvumelana okwenzekayo. I-ejenti yokumpompa ngokuvamile yakhiwa i-ejenti yokungenisa umoya kanye ne-ejenti yokunciphisa amanzi. Phakathi nenqubo enyakazayo yodaka olusanda kuxutshwa, inqwaba yamabhamuza omoya amancane ethulwa ukuze enze umphumela webhola, onganciphisa ukumelana nokungqubuzana phakathi kwezinhlayiya ezihlanganisiwe futhi uthuthukise ukusebenza kokupompa kodaka. . Phakathi nenqubo yokufafaza kodaka olufuthwe ngomshini, ukudlidliza okubangelwa ukuzungezisa iphampu yokudlulisa isikulufu kuzobangela kalula ukuthi udaka oluku-hopper luhlungwe, okuholela ekubeni kube nenani elincane lokungaguquguquki ungqimba olungaphezulu kanye nenani elikhulu lokungaguquguquki. ungqimba olungezansi, oluzoholela kalula ekuvinjweni kwamapayipi lapho umshini usebenza, futhi Ngemuva kokubunjwa, ikhwalithi yodaka ayifani futhi ijwayele ukomisa ukuncipha futhi ukuqhekeka. Ngakho-ke, lapho uklama izithasiselo eziyinhlanganisela zodaka lokuqhuma komshini, ezinye iziqinisi kufanele zengezwe ngokufanele ukuze kwehliswe isivinini sokuncibilika kodaka.
Ngenkathi abasebenzi benza ucwaningo lodaka olufuthwe ngomshini, umthamo wezithako eziyinhlanganisela wawungu-0.08%. Udaka lokugcina lwalusebenza kahle, ukusebenza kahle kokupompa, akukho mkhuba wokuwohloka phakathi nenqubo yokufafaza, futhi ubukhulu bobukhulu bokufafaza okukodwa bungafinyelela ku-25px.
