Ibhodlela lengilaziukugqoka kuyisixhumanisi esibalulekile sokwelashwa kwendawo emkhakheni wokupakishwa kwezimonyo. Yengeza ijazi elihle esitsheni sengilazi. Kulesi sihloko, sabelana ngesihloko mayelana nokwelashwa kokufafaza kwebhodlela lengilazi & namakhono wokufanisa umbala.
Ⅰ、Upende webhodlela lengilazi amakhono omsebenzi wokwakha wokufafaza
1. Sebenzisa i-diluent ehlanzekile noma amanzi ukulungisa upende ube yi-viscosity efanelekile yokufafaza. Ngemva kokulinganisa nge-viscometer ye-Tu-4, i-viscosity efanelekile ngokuvamile imizuzwana engu-18 kuya kwangu-30. Uma ingekho i-viscometer okwamanje, ungasebenzisa indlela ebonwayo: gudluza upende ngenduku (insimbi noma induku yokhuni) bese uyiphakamisela ekuphakameni okungama-20 cm bese uyeka ukuyibuka. Uma upende unganqamuki ngesikhathi esifushane (imizuzwana embalwa), bukhulu kakhulu; uma iphuka ngokushesha lapho ishiya umkhawulo ongaphezulu webhakede, incane kakhulu; uma imisa ekuphakameni okungama-20 cm, upende usemgqeni oqondile futhi uyeke ukugeleza bese uconsa phansi ngokuphazima kweso. Le viscosity ifaneleka kakhulu.
2. Umfutho womoya kufanele ulawulwe ku-0.3-0.4 MPa (3-4 kgf/cm2). Uma ingcindezi iphansi kakhulu, uketshezi lwepende ngeke lube ne-athomu kahle futhi i-pitting izokwakhiwa phezulu; uma ukucindezela kuphezulu kakhulu, kuzoncipha kalula futhi inkungu kapende izoba nkulu kakhulu, ezomosha izinto futhi ithinte impilo yomsebenzisi.
3. Ibanga phakathi kombhobho nendawo engaphezulu ngokuvamile lingama-200-300 mm. Uma iseduze kakhulu, izocwila kalula; uma ikude kakhulu, inkungu kapende izobe ingalingani futhi i-pitting izovela kalula, futhi uma umlomo wombhobho ukude nobuso, inkungu kapende izondiza ihambe endleleni, ibangele imfucuza. Usayizi othize wesikhawu kufanele ulungiswe ngokufanele ngokuya ngohlobo, i-viscosity kanye nomfutho womoya wepende yebhodlela lengilazi. Isikhawu sokufafaza upende owoma kancane singase sibe kude, futhi singase sibe kude lapho i-viscosity incane; lapho umfutho womoya uphakeme, isikhawu singase sibe kude, futhi singasondelana lapho ingcindezi incane; lokho okubizwa ngokusondelana nakude kubhekisela ebangeni lokulungisa phakathi kuka-10 mm no-50 mm. Uma idlula lolu hlu, kunzima ukuthola ifilimu yopende efanelekile.
4. Isibhamu se-spray singahanjiswa phezulu naphansi, kwesokunxele nakwesokudla, okungcono ngesivinini esifanayo se-10-12 m / min. I-nozzle kufanele ifuthwe phansi phezu kwento, futhi ukufafaza kwe-oblique kufanele kuncishiswe. Lapho ufutha kuzo zombili iziphetho zendawo, isandla esibambe isibhamu sokuqhumisa isibhamu kufanele sikhululwe ngokushesha ukuze kuncishiswe inkungu kapende, ngoba amaphethelo amabili obuso bento ngokuvamile athola izifutho ezingaphezu kwezimbili, futhi izindawo lapho ukuconsa kuconsa khona. okungenzeka kakhulu kwenzeke.
5. Uma ufutha, ungqimba olulandelayo kufanele lucindezele u-1/3 noma 1/4 wesendlalelo sangaphambilini, ukuze kungabikho ukuvuza. Lapho ufutha upende owomisa ngokushesha, kuyadingeka ukuwufafaza ngokulandelana ngesikhathi esisodwa. Umphumela wokufafaza kabusha awulungile.
6. Lapho ufutha endaweni evulekile ngaphandle, naka lapho umoya uya ngakhona (akufanelekile ukusebenza lapho kunemimoya enamandla), futhi osebenza naye kufanele ame aqonde lapho kunomoya ukuze avimbele inkungu kapende ukuthi ishayelwe endaweni efuthwe. ifilimu yopende futhi ibangele indawo eyimbudumbudu enamahloni.
7. Uhlelo lokufafaza luthi: kunzima kuqala, kulula kamuva, ngaphakathi kuqala, ngaphandle kamuva. Iphezulu kuqala, iphansi kamuva, indawo encane kuqala, indawo enkulu kamuva. Ngale ndlela, inkungu kapende efuthwe kamuva ngeke isakaze ifilimu kapende efuthwe futhi ilimaze ifilimu kapende efuthwe.
Ⅱ、Amakhono wokufanisa umbala webhodlela lengilazi
1. Isimiso esiyisisekelo sombala
Okubomvu + okuphuzi = okusawolintshi
Okubomvu + okuluhlaza okwesibhakabhaka = okunsomi
Ophuzi + onsomi = oluhlaza
2. Isimiso esiyisisekelo semibala ehambisanayo
Okubomvu nokuluhlaza kuyahambisana, okungukuthi, okubomvu kunganciphisa okuluhlaza, futhi okuluhlaza kunganciphisa okubomvu;
Okuphuzi nokunsomi kuyahambisana, okungukuthi, okuphuzi kunganciphisa okunsomi, futhi okunsomi kunganciphisa okuphuzi;
Okuluhlaza okwesibhakabhaka nokuwolintshi kuyahambisana, okungukuthi, okuluhlaza okwesibhakabhaka kunganciphisa i-orange, kanti i-orange inganciphisa okwesibhakabhaka;
3. Ulwazi oluyisisekelo lombala
Ngokuvamile, umbala abantu abakhuluma ngawo uhlukaniswe izingxenye ezintathu: i-hue, ukukhanya nokugcwala. I-Hue ibizwa nangokuthi i-hue, okungukuthi obomvu, owolintshi, ophuzi, oluhlaza okotshani, o-cyan, oluhlaza okwesibhakabhaka, onsomi, njll.; ukukhanya kubizwa nangokuthi ukukhanya, okuchaza ukukhanya nobumnyama bombala; ukugcwala kwendawo kubizwa nangokuthi i-chroma, echaza ukujula kombala.
4. Izimiso eziyisisekelo zokufanisa umbala
Ngokuvamile, ungasebenzisi izinhlobo ezingaphezu kwezintathu zopende ukufanisa imibala. Ukuhlanganisa obomvu, ophuzi noluhlaza okwesibhakabhaka ngesilinganiso esithile kungathola imibala ehlukene emaphakathi (okungukuthi imibala enama-hues ahlukene). Ngokwesisekelo semibala eyinhloko, ukwengeza omhlophe kungathola imibala ene-saturations ehlukene (okungukuthi imibala ene-shades ehlukene). Ngokwesisekelo semibala eyinhloko, ukwengeza emnyama kungathola imibala enokukhanya okuhlukile (okungukuthi imibala enokukhanya okuhlukile).
5. Izindlela eziyisisekelo zokufanisa umbala
Ukuxutshwa nokumataniswa kopende kulandela isimiso sombala okhiphayo. Imibala emithathu eyinhloko ibomvu, ophuzi noluhlaza okwesibhakabhaka, futhi imibala ehambisanayo iluhlaza, nsomi kanye newolintshi. Imibala ebizwa ngokuthi ehambisanayo iyimibala emibili yokukhanya exutshwe ngesilinganiso esithile ukuze kutholwe ukukhanya okumhlophe. Umbala ohambisanayo obomvu uluhlaza, umbala ohambisanayo wophuzi unsomi, futhi umbala ohambisanayo oluhlaza okwesibhakabhaka unowolintshi. Okusho ukuthi, uma umbala ubomvu kakhulu, ungakwazi ukwengeza oluhlaza; uma iphuzi kakhulu, ungakwazi ukwengeza onsomi; uma kuluhlaza okwesibhakabhaka kakhulu, ungangeza owolintshi. Imibala emithathu eyinhloko ibomvu, ophuzi, noluhlaza okwesibhakabhaka, futhi imibala ehambisanayo iluhlaza, onsomi, nowolintshi. Imibala ebizwa ngokuthi ehambisanayo iyimibala emibili yokukhanya exutshwe ngesilinganiso esithile ukuze kutholwe ukukhanya okumhlophe. Umbala ohambisanayo obomvu uluhlaza, umbala ohambisanayo wophuzi unsomi, futhi umbala ohambisanayo oluhlaza okwesibhakabhaka unowolintshi. Okungukuthi, uma umbala ubomvu kakhulu, ungakwazi ukwengeza oluhlaza; uma iphuzi kakhulu, ungakwazi ukwengeza onsomi; uma iluhlaza okwesibhakabhaka kakhulu, ungangeza owolintshi.
Ngaphambi kokumataniswa kombala, qala ngokunquma indawo yombala okufanele ifaniswe ngokomfanekiso ongezansi, bese ukhetha ama-hues amabili afanayo ukuze afane ngesilinganiso esithile. Sebenzisa into efanayo yebhodi lebhodlela lengilazi noma into yokusebenza ezofafazwa ukuze ihambisane nombala (ubukhulu be-substrate, ibhodlela lengilazi likasawoti we-sodium kanye nebhodlela lengilazi likasawoti we-calcium kuzobonisa imiphumela ehlukene). Uma ufanisa umbala, qala wengeze umbala oyinhloko, bese usebenzisa umbala ngamandla ombala aqinile njengombala wesibili, kancane kancane futhi ngezikhathi ezithile wengeze futhi ugovuze ngokuqhubekayo, futhi ubheke izinguquko zombala nganoma isiphi isikhathi, thatha amasampula bese usula, shayela, fafaza. noma uwacwilise kusampula ehlanzekile, bese uqhathanisa umbala nesampuli yoqobo ngemva kokuthi umbala uzinzile. Umgomo othi "kusuka ekukhanyeni kuye komnyama" kumele uqondwe kuyo yonke inqubo yokufanisa imibala.
