Ukucheba okuhlanganisiweyo kubhekiswa kwinto ethile yesamente, ukudityaniswa kakuhle, ukuxhuma, amanzi kunye nezinto ezahlukeneyo ezimiselwe ngokomsebenzi. Ngokwenani elithile, emva kokulinganiswa kwaye ixutywe kwisikhululo sokudibanisa, ithuthwe ukuya kwindawo yokusetyenziswa yilori yomxube. Gcina umxube wokulala kwisitya esikhethekileyo kwaye uyisebenzise ngexesha elichaziweyo. Umgaqo wokusebenzela wobukho omanzi oxubeneyo uyafana nekhonkrithi yentengiso, kwaye isikhululo sokudibanisa ikhonkrithi seTringte sinokufanelwa ngaxeshanye kuveliswe ngodaka oluxubeneyo.
I-1. Izibonelelo zodaka oluxubileyo
I-1) udaka oluxubeneyo oluxutywe lungasetyenziswa ngokuthe ngqo emva kokuba ithuthwele indawo ngaphandle kokusebenza, kodwa udaka kufuneka lugcinwe kwisikhongozeli;
2) udaka oluxubeneyo lulungiswa kumzi-mveliso oqeqeshiweyo, olufanelekileyo lokuqinisekisa nokulawula umgangatho wodaka;
3) Ukukhetha izinto ezingafunekiyo zodaka oluxubeneyo lukhulu. I-Aggregate ingome okanye imanzi, kwaye ayifuni komiswa, ke iindleko zinokuncitshiswa. Ukongeza, isixa esikhulu sentlabathi yomatshini eveliswa yinkunkuma yemveliso enjengokubhabha kunye nenkunkuma eqinileyo yeSoftway enjengesitayile, kodwa ikwahlula-hlula iindleko zodaka.
4) Indawo yokwakha inendawo elungileyo kunye nongcoliseko oluncinci.
I-2. Ukungalunganga kodaka oluxubileyo
1) Oko kufana nodaka oluxubeneyo kuxutywe namanzi kwisityalo semveliso yobungcali, kwaye ivolumu yezothutho inkulu ngexesha elinye, ayinakulawulwa ngokusetyenziswa kwenkqubela phambili yokwakha nokusetyenziswa. Ukongeza, udaka oluxubeneyo kufuneka lugcinwe kwisikhongozeli somoya emva kokuba uhanjiswe kwindawo yokwakha, ke i-Ash Pond kufuneka isethwe kwindawo;
2) Ixesha lokuhamba lithintelwe kwiimeko zendlela;
3) Oko kudaka olumanziweyo lugcinwe kwindawo yokwakha ixesha elide, kukho iimfuno ezithile zokusebenza, ukubeka ixesha kunye nokuzinza kwentsebenzo yokusebenza kodaka.
I-HydroxyPOpyl Methylcelcelcelose isetyenziswa njengearhente yokugcina amanzi kunye nokubuyisa i-tememe Isetyenziswe njenge-binder ekwindawo yokubeka phantsi i-Plaster, iphucula ukusasazeka kwaye inyusa ixesha lokusebenza. Umsebenzi wokugcinwa kwamanzi we-Hydroxypropyl Methylcelsele HPMC ithintela i-slickry ekrakra ngenxa yokomisa ngokukhawuleza emva kokukhulisa. Ukugcinwa kwamanzi yintsebenzo ebalulekileyo ye-hydroxypropyl methylcelcelgalose hpmc, kwaye kukwayindlela yokusebenza kwabantu abafakelweyo basekhaya abanikela ingqalelo. Izinto ezichaphazela ukusebenza kwamanzi ofaniso oluxubeneyo lubandakanya isixa se-HPMC songezwa, i-viscosity ye-HPMC, ukulunga kwamasuntswana, kunye neqondo lobushushu lendawo yokusetyenziswa.
Emva kokuchetywa okuxubeneyo kuhanjiswe kule ndawo, kufuneka igcinwe kwindawo engeyiyo eyomoya. Ukuba ukhetha isikhongozeli sentsimbi, impembelelo yokugcina yeyona nto iphambili, kodwa utyalomali luphakame kakhulu, olungahambelaniyo nokuqonda kunye nokusetyenziswa; Ungasebenzisa izitena okanye iibhloko ukwakha iphuli ye-Ash, uze usebenzise isitulo samanzi Nangona kunjalo, ukubethwa kokusebenza kwamanzi kubaluleke kakhulu, kwaye umgangatho wokwakha udaka lwamanzi kufuneka luqinisekiswe. Kungcono ukongeza i-hydroxypropyl methylcelgalose i-HPMC ye-HPMC ye-hpmc Umgangatho we-ash pond kufuneka ube nenqanaba lokuthambeka okuthile lokucoca ngokulula. I-Ash Pond kufuneka ifumane uphahla olunendawo eyaneleyo ukukhusela kwimvula nelanga. Udaka lugcinwe kwiphuli ye-Ash, kwaye umphezulu wechibi le-ash kufuneka igutyungelwe ngokupheleleyo ngendwangu yeplastiki yokuqinisekisa ukuba udaka lukwimeko evaliweyo.
Indima ebalulekileyo ye-HydroxyPOpyl Methylcelceluplose HPMC i-HPMC ye-Smambing kaManzi inezinto ezintathu zokugcina amanzi, kunye ne-Thixit Right Moges, kunye nesithathu kukunxibelelana nesamente. Inkqubo yokugcina amanzi ye-selsulose ether ixhomekeke ekufungeni lwamanzi kuludaka, ukwakhiwa kodaka, ubungqingqwa bodaka, kunye nexesha lokumiswa kwemibandela. Ukuphakama kwengqondo ye-Hydroxypropyl Methylceluplose, okungcono ukugcinwa kwamanzi.
Izinto ezichaphazela ukugcinwa kwamanzi kodaka lwamanzi emanziweyo kubandakanya i-visthesis ye-ethes, ukongeza kwixabiso, ukulunga kuthathelwa ingqalelo kwaye usebenzise iqondo lobushushu. Owona mkhulu we-viscosity ye-seluplose ether, engcono ukusebenza kwendlela yokugcina amanzi. I-Viscosity yiparamitha ebalulekileyo ye-HPMC. Kwimveliso efanayo, iziphumo ze-viscofity zilinganiswe ngeendlela ezahlukeneyo zahluke kakhulu, kwaye ezinye zinokuphinda-phinda umohluko. Ke ngoko, xa kuthelekiswa nokundwendwela, kufuneka kwenziwe phakathi kweendlela zovavanyo ezifanayo, kubandakanya neqondo lokushisa, i-rotor, njl.
Ngokubanzi, ukuphakama kwe-viscosity, eyona nto ilunge ngakumbi. Nangona kunjalo, ukuphakama okuphezulu kunye nokuphakathi kobunzima be-phudmc, ukuncipha okungahambelaniyo kunqulo lwayo kuya kuba nefuthe elibi kumandla kunye nokusebenza komsebenzi wokwakha. Ukuphakama kwe-viscofity, eyona nto icacileyo yokuthambisa kodaka, kodwa ayifani ngokuthe ngqo. Ukuphakama okuphezulu, kokukhona udaka olunamanzi luya kuba, oko kukuthi, ngexesha lolwakhiwo, lubonakaliswa njengokunamathela kwi-scraper kunye nokunamathela okuphezulu. Kodwa akuncedi ukonyusa amandla olwakhiwo lofudu lwamanzi. Ngexesha lokwakha, umsebenzi we-Anti-SAG akacacanga. Ngokuchasene noko, ezinye ze-hydroxypropyl methylceluplose kunye ne-viscofity ephantsi isebenza kakuhle ekuphuculeni amandla olwakhiwo lodaka lwamanzi.
Kwisifo esimanziweyo esixubeneyo, isixa esongeneyo se-itelulose ether HPMC iphantsi kakhulu, kodwa inokuyiphucula kakhulu ukusebenza kwendlela yokwakha yodaka oluxubileyo, kwaye yeyona nto iphambili echaphazela umsebenzi wokwakha. Ukukhetha okufanelekileyo kwe-hydropyl ye-hydylcelcelcelsulose kunempembelelo enkulu ekuphuculeni ukusebenza kodaka oluxubeneyo.
