Ungakuthuthukisa Kanjani Ukusebenza Kokhonkolo?

Ngokuqhathanisa kokuhlola, ukungezwa kwe-cellulose ether kungathuthukisa kakhulu ukusebenza kukakhonkolo ojwayelekile futhi kuthuthukise ukumpompa kukakhonkolo ompompa. Ukufakwa kwe-cellulose ether kuzonciphisa amandla okhonkolo.

Amagama angukhiye: i-cellulose ether; ukusebenza okuphathekayo; ukumpompa

1.Isingeniso

Ngokuthuthuka okuqhubekayo komphakathi, isidingo sokhonkolo wezohwebo siyakhula. Ngemva kweminyaka engaphezu kweshumi yokuthuthuka ngokushesha, ukhonkolo wezohwebo usungene esigabeni esivuthiwe. Ukhonkolo ohlukahlukene wezohwebo uhlangabezana nezidingo zamaphrojekthi ahlukahlukene. Kodwa-ke, emsebenzini wangempela, sithole ukuthi lapho kusetshenziswa ukhonkolo ompontshwa, ngokuvamile ngenxa yezizathu ezinjengokungasebenzi kahle kukakhonkolo kanye nezinga lesihlabathi esingazinzile, iloli lokupompa lizovinjelwa, futhi isikhathi esiningi kanye nabasebenzi bazomoshwa endaweni yokwakha. kanye nesiteshi sokuxuba, esizothinta iphrojekthi. izinga le. Ikakhulukazi ukhonkolo wezinga eliphansi, ukusebenza kwawo kanye nokumpompa kubi kakhulu, akuzinzile, futhi amathuba okuxhunywa kwamapayipi nokuqhuma aphezulu. Ngokuvamile, ukwandisa izinga lesihlabathi nokwandisa izinto zikasimende kungathuthukisa isimo esingenhla, kodwa futhi kuthuthukisa ikhwalithi yekhonkrithi. izindleko zempahla. Ezifundweni ezedlule, kwatholakala ukuthi ukungezwa kwe-cellulose ether kukhonkolo enegwebu kuzokhiqiza inani elikhulu lamabhamuza omoya amancane avaliwe enhlanganisela, okwandisa uketshezi lukakhonkolo, kuthuthukisa ukugcinwa kokuwa, futhi ngesikhathi esifanayo kudlala. iqhaza ekugcinweni kwamanzi nasekubambezelekeni odakeni lukasimende. Ngakho-ke, ukwengeza i-cellulose ether kukhonkolo evamile kufanele kube nomphumela ofanayo. Okulandelayo, ngokuhlolwa, ngaphansi kwesisekelo sesilinganiso sokuxuba njalo, inani elincane le-cellulose ether liyengezwa ukuze kubonwe ukusebenza kwengxube, kulinganise ukuminyana kwenqwaba emanzi, futhi kuvivinywe amandla okucindezela kakhonkolo 28d. Okulandelayo inqubo kanye nemiphumela yokuhlolwa.

2. Isivivinyo

2.1 Hlola izinto zokusetshenziswa

(1) Usimende uhlobo lweYufeng PO42.5 usimende.

(2) Izixube zamaminerali ezisebenzayo ezisetshenziswayo yi-Laibin Power Plant Class II fly ash kanye ne-Yufeng S75 class mineral powder.

(3) Iqoqo elihle liyisihlabathi esenziwe ngomshini we-limestone esikhiqizwe i-Guangxi Yufeng Concrete Co., Ltd., enemodulus ye-fineness engu-2.9.

(4) I-aggregate eqinile ingu-5-25 mm we-limestone ehleliwe ekhiqizwa yi-Yufeng Blasting Company.

(5) Isinciphisi samanzi yi-polycarboxylate esebenza kahle kakhulu yokunciphisa amanzi i-AF-CB ekhiqizwe yi-Nanning Nengbo Company.

(6) I-cellulose ether yi-HPMC ekhiqizwe yi-Kima Chemical Co., Ltd, ene-viscosity engu-200,000.

2.2 Indlela yokuhlola kanye nenqubo yokuhlola

(1) Ngaphansi kwesisekelo sokuthi isilinganiso se-water-binder nesilinganiso sesihlabathi kuyahambisana, yenza izivivinyo ngezilinganiso ezihlukene zokuhlanganisa, ulinganise ukuwohloka, ukuwohloka kokuphela kwesikhathi, kanye nokunwetshwa kwengxube entsha, ulinganise ukuminyana kwenqwaba yesampula ngayinye, futhi qaphela isilinganiso sokuxuba. Ukusebenza kokusebenza kwento kanye nokwenza irekhodi.

(2) Ngemva kokuhlolwa kokulahlekelwa kokuwohloka kwehora le-1, ingxube yesampula ngayinye yaphinde yaxutshwa ngokulinganayo futhi yalayishwa emaqenjini ama-2 ngokulandelana, futhi yelashwa izinsuku ezingu-7 nezinsuku ezingu-28 ngaphansi kwezimo ezijwayelekile.

(3) Uma iqembu le-7d lifinyelela eminyakeni yobudala, yenza ukuhlolwa okuphuthumayo ukuze uthole ubudlelwano phakathi komthamo namandla we-7d, futhi uthole inani lomthamo x ngokusebenza okuhle komsebenzi namandla aphezulu.

(4) Sebenzisa umthamo x ukwenza izivivinyo eziphathekayo ezinamalebula ahlukene, futhi uqhathanise amandla amasampula angenalutho ahambisanayo. Thola ukuthi angakanani amandla okukhonkolo amabanga ahlukene athintwa i-cellulose ether.

2.3 Imiphumela yokuhlolwa nokuhlaziya

(1) Ngesikhathi sokuhlolwa, bheka isimo nokusebenza kwengxube entsha yamasampuli anemithamo ehlukene, bese uthatha izithombe zamarekhodi. Ngaphezu kwalokho, incazelo yesimo nokusebenza kwesampula ngayinye yengxube entsha nayo iyarekhodwa.

Ukuhlanganisa isimo nokusebenza kwengxube entsha yamasampula anemithamo ehlukene kanye nencazelo yesimo nezakhiwo zengxube entsha, kungatholakala ukuthi iqembu elingenalutho elingenayo i-cellulose ether linokusebenza okuvamile, ukopha kanye nokungafinyeleli kahle kwe-encapsulation . Lapho i-cellulose ether yengezwa, wonke amasampula ayengenayo into yokopha, futhi nokusebenza kwaba ngcono kakhulu. Ngaphandle kwesampula E, amanye amaqembu amathathu abe noketshezi oluhle, ukunwetshwa okukhulu, futhi kulula ukupompa nokwakha. Lapho umthamo ufinyelela cishe ku-1‰, ingxube iba yi-viscous, izinga lokunwetshwa liyancipha, futhi uketshezi luyisilinganiso. Ngakho-ke, umthamo ngu-0.2‰～0.6‰, okungathuthukisa kakhulu ukusebenza nokusebenza nokumpompa.

(2) Phakathi nokuhlolwa, ukuminyana kwenqwaba yengxube kwalinganiswa, futhi kwaphuka ngemva kwezinsuku ezingu-28, futhi kwatholwa imithetho ethile.

Kungabonakala ebudlelwaneni obuphakathi kokuminyana kwenqwaba/amandla kanye nokuminyana kwenqwaba/amandla engxube entsha kanye nomthamo ukuthi ukuminyana kwenqwaba yengxube entsha kuncipha njengoba umthamo we-cellulose ether ukhula. Amandla okucindezela nawo ehla ngokwanda kokuqukethwe kwe-cellulose ether. Kuyahambisana nokhonkolo wegwebu ofundwe nguYuan Wei.

(3) Ngokuhlola, kutholakala ukuthi umthamo ungakhethwa njengo-0.2‰, engakwazi kuphela ukuthola ukusebenza okuhle kokusebenza, kodwa futhi nokulahlekelwa amandla okuncane uma kuqhathaniswa. Bese, ukuhlolwa komklamo C15, C25, C30, C35 4 amaqembu angenalutho namaqembu angu-4 ngokulandelanayo axutshwe no-0.2‰i-cellulose ether.

Bheka ukusebenza kwenhlanganisela entsha bese uyiqhathanisa nesampula engenalutho. Bese ufaka isikhunta sokuphulukiswa okujwayelekile, bese wephula isikhunta izinsuku ezingama-28 ukuze uthole amandla.

Ngesikhathi sokuhlolwa, kutholwe ukuthi ukusebenza kwamasampula engxube entsha ahlanganiswe ne-cellulose ether kuye kwathuthukiswa kakhulu, futhi ngeke kube khona ukuhlukaniswa noma ukopha nhlobo. Nokho, izingxube ezisezingeni eliphansi uma kuqhathaniswa ze-C15, i-C20, ne-C25 kusampula elingenalutho kulula ukuzihlukanisa futhi zophe ngenxa yenani elincane lomlotha. Amabanga e-C30 nangaphezulu nawo asethuthukile. Ingabonwa kudatha ekuqhathaniseni amandla amalebula ahlukene ahlanganiswe no-2‰i-cellulose ether kanye nesampula elingenalutho amandla kakhonkolo ancishiswa ngokwezinga elithile lapho i-cellulose ether yengezwa, futhi ubukhulu bokwehla kwamandla buyanda ngokukhula kwelebula.

3. Isiphetho sokuhlola

(1) Ukwengeza i-cellulose ether kungathuthukisa ukusebenza kukakhonkolo wezinga eliphansi futhi kuthuthukise ukudonsa.

(2) Ngokungezwa kwe-cellulose ether, ukuminyana kwenqwaba kakhonkolo kuncipha, futhi inani likhulu, liba lincane ukuminyana kwenqwaba.

(3) Ukufaka i-cellulose ether kuzonciphisa amandla kakhonkolo, futhi ngokwanda kokuqukethwe, izinga lokunciphisa lizokhula.

(4) Ukwengeza i-cellulose ether kuzonciphisa amandla kakhonkolo, futhi ngokwanda kwebanga, ubukhulu bokuncipha buzokhula, ngakho-ke akufanelekile ukusetshenziselwa ukhonkolo wezinga eliphezulu.

(5) Ukwengeza i-cellulose ether kungasetshenziswa ukuthuthukisa ukusebenza kwe-C15, C20, ne-C25, futhi umphumela ulungile, kuyilapho ukulahlekelwa amandla kungekukhulu. Inqubo yokumpompa inganciphisa kakhulu ithuba lokuvaleka kwamapayipi futhi ithuthukise ukusebenza kahle komsebenzi.
