Ukwelashwa kokufuthwa kobuso bebhodlela lengilazi kanye nokwabelana ngamakhono okufanisa imibala

Ukugqoka ibhodlela lengilazi, emkhakheni wezinto zokupakisha izimonyo, lokhu kuyisixhumanisi esibalulekile sokwelashwa kwendawo, unezela ungqimba lobuhle esitsheni sengilazi, kulesi sihloko, sabelana ngesihloko mayelana nokwelashwa kokufuthwa kwendawo yebhodlela lengilazi kanye namakhono okufanisa imibala kuiphakheji yothingo lwaseShanghai.

一,

Amakhono okusebenza kokwakha ngokufafaza upende webhodlela lengilazi

1. Sebenzisa i-diluent ehlanzekile noma amanzi ukuze ulungise upende ube yi-viscosity efanelekile yokufafaza. I-viscometer efanelekile ngokuvamile ingamasekhondi angu-18 kuya kwangu-30 njengoba kulinganiswa yi-viscometer ye-Tu-4. Uma kungekho viscometer isikhathi esithile, indlela ebonakalayo ingasetshenziswa: hlanganisa upende ngenduku (insimbi noma induku yokhuni) bese uwuphakamisa ufike ku-20 cm ukuphakama ukuze uyeke ukubukisisa. Uwugqinsi kakhulu; uma umugqa uphukile ngokushesha nje lapho ushiya umkhawulo ongaphezulu womgqomo, uba mncane kakhulu; uma umi ku-20 cm ukuphakama, uketshezi lopende luzokwakha umugqa oqondile, futhi ukugeleza kuzoma ngokushesha bese kuconsa. Lokhu kugqama kufaneleke kakhulu.

2. Umfutho womoya ulawulwa kangcono ku-0.3-0.4 MPa (3-4 kgf/cm2). Uma umfutho uphansi kakhulu, uketshezi lopende luzoncishiswa kakhulu, futhi imigodi izokwakheka ebusweni; uma umfutho uphakeme kakhulu, uzowa kalula, futhi inkungu yopende izoba nkulu kakhulu, okungeke nje kuchithe izinto, kodwa futhi kuthinte impilo yomqhubi.

3. Isikhawu esiphakathi kwe-nozzle kanye nobuso bento ngokuvamile singu-200-300 mm. Uma sisondele kakhulu, kulula ukugoba; sikude kakhulu, inkungu yopende ayilingani futhi ithambekele ekuqhekekeni, futhi inkungu yopende ihlakazeke endleleni esuka ku-nozzle kude nobuso bento, okubangela ukungcola. Usayizi othize wesikhawu kufanele ulungiswe ngokufanelengokohlobo lopende webhodlela lengilazi, i-viscosity kanye nomfutho womoya. Isikhathi sokufafaza sopende owomisa kancane singaba kude, lapho i-viscosity incane, singaba kude; lapho umfutho womoya uphezulu, isikhathi singaba kude, kanti umfutho ungaba ncane uma umfutho uncane; Uma udlula leli banga, kuba nzima ukuthola ifilimu yopende efanele.
4. Isibhamu sokufutha singahanjiswa phezulu naphansi, kwesobunxele nakwesokudla, okungcono ngesivinini esingu-10-12 m/min, futhi umlomo kufanele ufafazwe uqonde phezulu naphansi kwento ukuze kuncishiswe ukufutha okugobile. Uma ufafazwa kuzo zombili izinhlangothi zobuso bento, isandla esidonsa i-trigger yesibhamu sokufutha kufanele sikhululwe ngokushesha ukuze kuncishiswe inkungu yopende. Ngenxa yokuthi izinhlangothi ezimbili zobuso bento zivame ukudinga ukufuthwa ngaphezu kokuphindwe kabili, yindawo okungenzeka kakhulu ukuthi ibangele ukugoba.

5. Uma ufafaza, i-pass elandelayo kufanele icindezelwe ku-1/3 noma 1/4 ye-pass yangaphambilini, ukuze kungabikho ukuvuza kwe-spray. Uma ufafaza upende owomisa ngokushesha, ufafaza ngokulandelana ngesikhathi. Umphumela we-spray awulungile.

6. Uma ufafaza endaweni evulekile yangaphandle, naka indlela umoya ohamba ngayo (ungasebenzi uma umoya unamandla), futhi opharetha kufanele ame ngendlela umoya ohamba ngayo ukuze avimbele inkungu yopende ukuthi ingapheshulwa umoya uye efilimini yopende efafaziwe futhi ibangele ubuso obuyihlazo obuyi-granular.

7. Uhlelo lokufafaza luthi: kuqala kunzima bese kuba lula, kuqala ngaphakathi bese kuba ngaphandle. Okokuqala phezulu, bese kuba phansi, kuqala indawo encane bese kuba indawo enkulu. Ngale ndlela, inkungu yopende efafaziwe ngeke ichithekele efilimini yopende efafaziwe futhi yonakalise ifilimu yopende efafaziwe.

Amakhono okufanisa umbala wopende webhodlela lengilazi

1. Isimiso esiyisisekelo sobunono
obomvu + ophuzi = orenji
obomvu + oluhlaza okwesibhakabhaka = onsomi
ophuzi + onsomi = oluhlaza okotshani

2. Isimiso esiyisisekelo semibala ehambisanayo
Okubomvu nokuluhlaza kuyahambisana, okungukuthi, okubomvu kunganciphisa okuluhlaza, kanti okuluhlaza kunganciphisa okubomvu;
Okuphuzi nokunsomi kuyahambisana, okungukuthi, okuphuzi kunganciphisa okunsomi, kanti okunsomi kunganciphisa okuphuzi;
Okuluhlaza okwesibhakabhaka kuyahambisana no-orenji, okungukuthi, okuluhlaza okwesibhakabhaka kunganciphisa i-orenji, kanti okuluhlaza okwesibhakabhaka kunganciphisa i-orenji;

3. Izisekelo zombala
Abantu abavamile bathi umbala uhlukaniswe izakhi ezintathu: umbala, ukukhanya kanye nokugcwala. Umbala ubizwa nangokuthi umbala, okungukuthi, obomvu, owolintshi, ophuzi, oluhlaza okotshani, oluhlaza okotshani, oluhlaza okwesibhakabhaka, onsomi, njll.; ukukhanya kubizwa nangokuthi ukukhanya, okuchaza ukukhanya kanye nobumnyama bombala; ukugcwala kubizwa nangokuthi i-chroma,okuchaza ukujula kombala.

4. Izimiso eziyisisekelo zokufanisa imibala
Ngokuvamile ungasebenzisi izinhlobo ezingaphezu kwezintathu zopende wombala. Imibala ehlukene ephakathi nendawo (okungukuthi, imibala enemibala ehlukene) ingatholakala ngokuxuba imibala ebomvu, ephuzi, neluhlaza okwesibhakabhaka ngesilinganiso esithile. Ngokusekelwe kumbala oyinhloko, ukwengeza okumhlophe, ungathola imibala ene-saturation ehlukene (okungukuthi, imibala enemibala ehlukene). Ngokusekelwe kumbala oyinhloko, ukwengeza omnyama, ungathola imibala enokukhanya okuhlukile (okungukuthi, imibala enokukhanya okuhlukile).

5. Amakhono ayisisekelo okufanisa imibala

Ukuxuba nokuhlanganisa imibala yamapende kulandela isimiso sombala osusayo, imibala emithathu eyinhloko ibomvu, iphuzi, nohlaza okwesibhakabhaka, kanti imibala yayo ehambisanayo iluhlaza okwesibhakabhaka, onsomi, no-orenji. Okubizwa ngokuthi imibala ehambisanayo yimibala emibili exutshwe ngesilinganiso esithile ukuthola ukukhanya kombala omhlophe, umbala ohambisanayo obomvu uluhlaza okwesibhakabhaka, umbala ohambisanayo ophuzi ubomvu nsomi, kanti umbala ohambisanayo oluhlaza okwesibhakabhaka u-orenji. Okusho ukuthi, uma umbala ubomvu kakhulu, ungangeza oluhlaza; uma uphuzi kakhulu, ungangeza onsomi; uma uluhlaza okwesibhakabhaka kakhulu, ungangeza onsomi. Imibala emithathu eyinhloko ibomvu, iphuzi, nohlaza okwesibhakabhaka, kanti imibala yayo ehambisanayo iluhlaza okwesibhakabhaka, onsomi, no-orenji. Okubizwa ngokuthi imibala ehambisanayo yimibala emibili exutshwe ngesilinganiso esithile ukuthola ukukhanya kombala omhlophe, umbala ohambisanayo obomvu uluhlaza okwesibhakabhaka, umbala ohambisanayo ophuzi ubomvu nsomi, kanti umbala ohambisanayo oluhlaza okwesibhakabhaka u-orenji. Okusho ukuthi, uma umbala ubomvu kakhulu, ungangeza oluhlaza; uma uphuzi kakhulu, ungangeza onsomi; uma uluhlaza okwesibhakabhaka kakhulu, ungangeza onsomi.

Ngaphambi kokufanisa imibala, qala ngokunquma ukuthi umbala ozohlanganiswa ukuphi esithombeni ngokwesithombe esilandelayo, bese ukhetha imibala emibili efanayo yokuxuba ngesilinganiso esithile. Sebenzisa ipuleti lebhodlela lengilazi elifanayo noma isiqeshana somsebenzi ozofuthwa ukuze kufaniswe imibala (ubukhulu be-substrate, ibhodlela lengilazi likasawoti we-sodium kanye nebhodlela lengilazi likasawoti we-calcium kuzobonisa imiphumela ehlukile). Lapho uxuba imibala, qala ngokufaka umbala oyinhloko, bese usebenzisa umbala onamandla okufaka umbala njengomsizi, uwufake kancane kancane futhi ngezikhathi ezithile bese uqhubeka uvuselela, ukuze ubone ushintsho lombala nganoma yisiphi isikhathi, bese uthatha isampula ngokusula, ukuxubha, ukufutha noma ukunamathisela kusampula ehlanzekile. Ngemva kokuba umbala uzinzile, qhathanisa umbala nesampula yokuqala. Kuyo yonke inqubo yokufanisa imibala, isimiso "sokusuka ekujuleni kuya ebumnyameni" kumele siqondwe.
