Kuyashisa futhi kuyashisa muva nje.Emehlweni abasebenzi bemishini, sidinga ukubhekana noketshezi olufanayo "olushisayo" unyaka wonke, ngakho-ke ukusebenzisa ngokunengqondo uketshezi lokusika nokulawula izinga lokushisa nakho kungenye yamakhono ethu adingekayo.Manje ake sabelane nawe ngezimpahla ezomile.
1. Lapho ucubungula insimbi evuthayo, sicela usebenzise uketshezi olufanele lokusika ukuze kucutshungulwe insimbi evuthayo.Ikakhulukazi uma umlilo ubangelwa lapho kucutshungulwa insimbi evuthayo kusetshenziswa uketshezi lokusika oluncibilika emanzini, amanzi nensimbi evuthayo kuzosabela, okungase kuholele ekushisweni kwesiqhumane noma ukuqhuma komhwamuko okubangelwa i-hydrogen.
2. Ungasebenzisi uketshezi olusikiwe olunephoyinti eliphansi lokuthungela (i-petroleum ye-Class 2, njll., indawo yokuthungela engaphansi kuka-70 ℃).Uma kungenjalo, kuzodala umlilo.Ngisho nalapho kusetshenziswa uketshezi lwe-petroleum ye-Class 3 (iphoyinti lokuvutha 70 ℃~200 ℃), i-petroleum ye-Class 4 (iphoyinti lokuthungela elingu-200 ℃~250 ℃) kanye ne-flame retardant (iphoyinti lokuvutha ngaphezu kuka-250 ℃) kungenzeka ukubasa.Naka ngokugcwele isimo nezindlela zokusetshenziswa, njengokulawula ukukhiqizwa kwentuthu kawoyela.
3. Enqubweni yokusebenzisa uketshezi lokusika, qaphela ukugwema ukutholakala okwanele noma okungalungile koketshezi lokusika.Esimeni lapho kungekho khona ukunikezwa okuvamile koketshezi olusikiwe, izinhlansi noma ukushisa okushayisanayo kungase kwenzeke ezimeni zokucubungula, okungase kubangele ama-chips noma uketshezi olusikiwe locezu olushayo lubambe umlilo, ngaleyo ndlela kubangele umlilo.Kudingeka ukugwema ukutholakala okwanele noma okungalungile koketshezi lokusika, luhlanze ukuze ugweme ukuvaleka kwepuleti ye-adaptha ye-chip kanye nesihlungi sethangi eliwuketshezi lokusika, futhi uligcwalise ngokushesha lapho inani loketshezi lokusika ethangini lokusika lehla.Sicela uqinisekise ukusebenza okuvamile kwepompo yamanzi okusika njalo.
4. Uketshezi lokusika oluwohlokayo kanye namafutha okugcoba (amafutha, uwoyela) kuyingozi kakhulu emzimbeni womuntu.Ungawasebenzisi.Sicela uthintane nomkhiqizi mayelana nendlela yokwahlulela ukuwohloka koketshezi lokusika kanye namafutha okugcoba.Sicela ugcine futhi ulahle ngokwemiyalelo yomkhiqizi.
5. Zama ukugwema ukusebenzisa uketshezi olusikiwe kanye namafutha okugcoba (amafutha, uwoyela) angonakalisa i-polycarbonate, i-neoprene (NBR), irabha ye-nitrile ye-hydrogenated (HNBR), i-fluororubber, inayiloni, i-propylene resin ne-ABS resin.Ngaphezu kwalokho, lapho amanzi okuhlanjululwa equkethe inani elikhulu le-chlorine esele, lezi zinto nazo zizowohloka.Lezi zinto zisetshenziswa njengezinto zokupakisha kulo mshini.Ngakho-ke, uma ukupakishwa kunganele, kungabangela ukushaqeka kukagesi ngenxa yokuvuza kagesi noma ukushisa ndawonye ngenxa yokuphuma kwamafutha okugcoba.
6. Ukukhethwa nokusetshenziswa koketshezi lokusika
Uketshezi lokusika lubhekisela ohlotsheni lokuthambisa okuxubile olusetshenziselwa ukugcoba nokupholisa amathuluzi omshini kanye nezingxenye zomshini ngesikhathi sokusika insimbi, okungabuye kubizwe ngokuthi uketshezi lwensimbi (amafutha).Ngaphezu kwalokho, ekusebenzeni kokukhiqiza, uketshezi lokusika lunamagama esintu ahlukene ngokwezikhathi zokusetshenziswa ezahlukene.Isibonelo: uketshezi lokusika olusetshenziselwa ukusika nokugaya uketshezi olusetshenziselwa ukugaya;Amafutha okucweba asetshenziselwa ukujula;Amafutha okupholisa amagiya okuhobha nokubunjwa kwegiya.
Ukusika uhlobo lwe-fluid
Amafutha asekelwe emanzini (emulsion, microemulsion, synthetic fluid)
Ukusetshenziswa okunconyiwe koketshezi lokusika emishinini yokumba iqembu kanye neyokuthinta
·Ngoketshezi olusikiwe olusetshenziswayo, sicela ulandele imiyalelo yomkhiqizi yokuphatha kahle i-PH, izinga lokuxutshwa lesisombululo sesitoko namanzi okuhlanjululwa, ukugcwala kukasawoti wamanzi okuhlanjululwa, kanye nemvamisa yokushintsha uketshezi olusikayo.
·Uketshezi lokusika luzoncishiswa kancane kancane ngesikhathi sokusetshenziswa.Lapho uketshezi lokusika lunganele, kufanele lugcwaliswe ngesikhathi.Uma usebenzisa uketshezi lokusika oluncibilika emanzini, ngaphambi kokufaka amanzi kanye noketshezi lwangempela ethangini lamafutha, kufanele lugqugquzelwe ngokugcwele kwezinye iziqukathi, bese lufakwa ngemva kokuba luhlakazwe ngokuphelele.
Izindaba ezidinga ukunakwa
1. Uketshezi lokusika oluboniswe ngezansi luzoba nomthelela omkhulu emshinini futhi lungabangela ukwehluleka.Ungayisebenzisi.
Ukusika uketshezi oluqukethe isulfure enomsebenzi ophezulu.Ezinye ziqukethe isibabule esinomsebenzi ophakeme kakhulu, esingase sigqwalise ithusi, isiliva nezinye izinsimbi futhi sibangele izingxenye ezingasebenzi lapho singena emshinini.
Uketshezi lokusika lwe-synthetic olunokungena okuphezulu.Okunye okusaketshezi okusikayo okufana ne-polyglycol kunokudlulela okuphezulu kakhulu.Uma sezingene emshinini, zingadala ukonakala kwe-insulation noma izingxenye ezimbi.
Uketshezi lokusika oluncibilika emanzini olune-alkalinity ephezulu.Okunye okusamanzi okusika okusetshenziselwa ukuthuthukisa inani le-PH ngama-aliphatic alcohol amine ane-alkalinity eqinile engaphezu kuka-PH10 ekuhlambulukeni okujwayelekile, futhi izinguquko zamakhemikhali ezibangelwa ukunamathela kwesikhathi eside zingase ziholele ekuwohlokeni kwezinto ezinjengama-resin.Uketshezi lokusika olune-chlorine.Oketshezini olusikiwe oluqukethe upharafini one-chlorine nezinye izakhi ze-chlorine, ezinye zingase zibe nomthelela omkhulu ku-resin, irabha nezinye izinto, okubangela izingxenye ezimbi.
2. Njalo khipha amafutha antantayo ethangini likaketshezi lokusika ukuze ulondoloze isimo sokungantanti kwamafutha.Inani le-sludge lingalawulwa ngokuvimbela inani lamafutha oketshezini lokusika.
3. Njalo gcina uketshezi olusikiwe lusesimweni esisha.Uketshezi olusha olusikiwe lunomsebenzi wokwenza kabusha i-emulsifying okuqukethwe kwamafutha ku-sludge kawoyela ngomsebenzi ongaphezulu, futhi kunomphumela othile wokuhlanza odongeni lwamafutha olunamathele ethuluzini lomshini.
