Ibhotile yeglasiukugquma likhonkco lonyango lomphezulu obalulekileyo kwinkalo yokupakishwa kwezithambiso. Yongeza idyasi entle kwisitya seglasi. Kweli nqaku, sabelana ngenqaku malunga nonyango lokutshiza ibhotile yeglasi kunye nezakhono zokuthelekisa umbala.
Ⅰ、Izakhono zokusebenza zokutshiza ibhotile yeglasi yokutshiza
1. Sebenzisa i-diluent ecocekileyo okanye amanzi ukulungisa ipeyinti kwi-viscosity efanelekileyo yokutshiza. Emva kokulinganisa nge-viscometer ye-Tu-4, i-viscosity efanelekileyo ngokuqhelekileyo i-18 ukuya kwi-30 imizuzwana. Ukuba akukho viscometer okwangoku, ungasebenzisa indlela ebonakalayo: ugxobhoze ipeyinti ngentonga (intsimbi okanye intonga yokhuni) kwaye uyiphakamise ukuya kubude be-20 cm kwaye uyeke ukujonga. Ukuba ipeyinti ayiphuli ngexesha elifutshane (imizuzwana embalwa), inzima kakhulu; ukuba ithe yaphuka kamsinya nje ekuphumeni kwayo eluphethweni olungasentla lwe-emele, ibhityile kakhulu; xa imisa ekuphakameni kwama-20 cm, ipeyinti ikwindlela ethe tye kwaye iyeke ukuqukuqela kwaye ithontsize phantsi ngephanyazo. Le viscosity ifanelekile ngakumbi.
2. Uxinzelelo lomoya kufuneka ulawulwe kwi-0.3-0.4 MPa (3-4 kgf / cm2). Ukuba uxinzelelo luphantsi kakhulu, ulwelo lwepeyinti aluyi kuba ne-atomized kakuhle kwaye i-pitting iya kubumba phezulu; ukuba uxinzelelo luphezulu kakhulu, luya kuncipha ngokulula kwaye inkungu yepeyinti iya kuba nkulu kakhulu, eya kuchitha izinto kwaye ichaphazele impilo yomsebenzisi.
3. Umgama phakathi kombhobho kunye nomphezulu jikelele ngu-200-300 mm. Ukuba isondele kakhulu, iya kugoba ngokulula; ukuba ikude kakhulu, inkungu yepeyinti iya kungalingani kwaye i-pitting iya kubonakala ngokulula, kwaye ukuba umlomo wombhobho ukude nomphezulu, inkungu yepeyinti iya kubhabha endleleni, ibangele inkunkuma. Ubungakanani obuthile bekhefu kufuneka bulungiswe ngokufanelekileyo ngokohlobo, i-viscosity kunye noxinzelelo lomoya wepeyinti yebhotile yeglasi. Ikhefu lokutshiza ipeyinti eyomileyo kancinci linokuba kude, kwaye linokuba kude xa i-viscosity incinci; xa uxinzelelo lomoya luphezulu, ikhefu linokuba lide, kwaye linokuba lisondele xa uxinzelelo luncinci; okubizwa ngokuba kufutshane nangaphezulu kubhekiselele kuluhlu lohlengahlengiso phakathi kwe-10 mm kunye ne-50 mm. Ukuba idlula olu luhlu, kunzima ukufumana ifilimu yepeyinti efanelekileyo.
4. Umpu wokutshiza unokushenxiswa phezulu naphantsi, ukhohlo nasekunene, ngokukhethekileyo kwisantya esifanayo se-10-12 m / min. I-nozzle kufuneka itshizwe icwecwe phezu kwendawo, kwaye ukutshiza nge-oblique kufuneka kuncitshiswe. Xa utshiza kuzo zozibini iziphelo zomphezulu, isandla esibambe isitshizi sokutshiza kufuneka sikhululwe ngokukhawuleza ukunciphisa inkungu yepeyinti, kuba iziphelo ezimbini zomphezulu wento zihlala zifumana izitshizi ezingaphezu kwesibini, kwaye ziindawo apho kuthontsiza khona. kakhulu kunokwenzeka.
5. Xa utshiza, uluhlu olulandelayo kufuneka lucinezele i-1/3 okanye i-1/4 yoluhlu lwangaphambili, ukwenzela ukuba kungabikho ukuvuza. Xa utshiza ipeyinti yokumisa ngokukhawuleza, kuyimfuneko ukuyitshiza ngokulandelelana ngexesha elinye. Isiphumo sokutshiza kwakhona asifanelekanga.
6. Xa utshiza kwindawo evulekileyo ngaphandle, nikela ingqalelo kwicala lomoya (akufanelanga ukusebenza kwimimoya ebhudla ngamandla), kwaye umsebenzi kufuneka eme kwicala lomoya ukuthintela inkungu yepeyinti ukuba ivuthelwe kwindawo etshiziweyo. ifilimu yepeyinti kwaye ibangele umphezulu ohlazekileyo we-granular.
7. Umyalelo wokutshiza kukuba: kunzima kuqala, kulula kamva, ngaphakathi kuqala, ngaphandle kamva. Iphezulu kuqala, iphantsi kamva, indawo encinci kuqala, indawo enkulu kamva. Ngale ndlela, inkungu yepeyinti etshizwe kamva ayiyi kutshiza kwifilim yepeyinti etshiziweyo kwaye yonakalise ifilimu yepeyinti etshiziweyo.
Ⅱ、Ipeyinti yeglasi yeglasi izakhono zokuthelekisa umbala
1. Umgaqo osisiseko wombala
Obomvu + tyheli = orenji
Ebomvu + eluhlaza = mfusa
Mthubi + omfusa = eluhlaza
2. Umgaqo osisiseko wemibala ehambelanayo
Ubomvu kunye nohlaza ziyancedisana, oko kukuthi, obomvu unokunciphisa uhlaza, kunye nohlaza kunokunciphisa obomvu;
Iphuzi kunye nemfusa ziyahambelana, oko kukuthi, i-yellow inokunciphisa imfusa, kwaye imfusa inokunciphisa i-yellow;
I-Blue kunye ne-orange iyancedisana, oko kukuthi, i-blue inokunciphisa i-orange, kunye ne-orange inokunciphisa i-blue;
3. Ulwazi olusisiseko lombala
Ngokuqhelekileyo, umbala abantu abathetha ngawo wahlulahlulwe kwizinto ezintathu: i-hue, ukukhanya kunye nokugcwala. I-Hue ikwabizwa ngokuba yi-hue, okt ebomvu, e-orenji, emthubi, eluhlaza, e-cyan, eluhlaza okwesibhakabhaka, emfusa, njl. ukukhanya kukwabizwa ngokuba kukukhanya, okuchaza ukukhanya nobumnyama bombala; ukuzaliseka kwakhona kukwabizwa ngokuba yichroma, echaza ubunzulu bombala.
4. Imigaqo esisiseko yokudibanisa umbala
Ngokubanzi, musa ukusebenzisa ngaphezulu kweentlobo ezintathu zepeyinti ukuthelekisa umbala. Ukudibanisa obomvu, omthubi kunye nobhlowu ngokwemilinganiselo ethile kunokufumana imibala eyahlukileyo ephakathi (oko kukuthi imibala enemibala eyahlukeneyo). Ngokwesiseko semibala ephambili, ukongeza umhlophe unokufumana imibala ene-saturations eyahlukeneyo (oko kukuthi imibala enemithunzi eyahlukeneyo). Ngokwesiseko semibala ephambili, ukongeza omnyama kunokufumana imibala enokukhanya okwahlukileyo (oko kukuthi imibala enokukhanya okwahlukileyo).
5. Ubuchule obusisiseko bokudibanisa umbala
Ukuxuba kunye nokudibanisa iipende kulandela umgaqo wombala okhuphayo. Imibala emithathu ephambili ibomvu, tyheli kunye nebhlowu, kwaye imibala yazo ehambelanayo iluhlaza, mfusa kunye neorenji. Imibala ebizwa ngokuba yimibala ehambelanayo yimibala emibini yokukhanya exutywe kumlinganiselo othile ukufumana ukukhanya okumhlophe. Umbala ohambelanayo obomvu uluhlaza, umbala ohambelanayo wophuzi umfusa, kunye nombala ohambelanayo oluhlaza okwesibhakabhaka. Oko kukuthi, ukuba umbala ubomvu kakhulu, unokongeza uhlaza; ukuba iphuzi kakhulu, unokongeza imfusa; ukuba iblue kakhulu, unokongeza iorenji. Imibala emithathu ephambili ibomvu, tyheli, nebhlowu, kwaye imibala ehambelanayo iluhlaza, mfusa, neorenji. Imibala ebizwa ngokuba yimibala ehambelanayo yimibala emibini yokukhanya exutywe kumlinganiselo othile ukufumana ukukhanya okumhlophe. Umbala ohambelanayo obomvu uluhlaza, umbala ohambelanayo wophuzi umfusa, kunye nombala ohambelanayo oluhlaza okwesibhakabhaka. Oko kukuthi, ukuba umbala ubomvu kakhulu, unokongeza uhlaza; ukuba iphuzi kakhulu, unokongeza imfusa; ukuba iblue kakhulu, unokongeza iorenji.
Ngaphambi kokudibanisa umbala, qala ujonge indawo yombala oza kuhambelana nayo ngokomfanekiso ongezantsi, uze ukhethe ii-hues ezimbini ezifanayo ukuze zihambelane ngomlinganiselo othile. Sebenzisa imathiriyeli yeglasi yebhotile efanayo okanye into yokusebenza eza kutshizwa ukuze ihambelane nombala (ubukhulu besubstrate, ibhotile yeglasi yetyuwa yesodium kunye nebhotile yeglasi yetyuwa yecalcium iya kubonisa iziphumo ezahlukeneyo). Xa utshatisa umbala, qala yongeza owona mbala uphambili, emva koko usebenzise umbala ngamandla ombala oqinileyo njengombala wesibini, kancinci kwaye ngokungenasiphelo udibanise kwaye ushukumise ngokuqhubekayo, kwaye ujonge utshintsho lombala nangaliphi na ixesha, thatha iisampulu kwaye usule, ibhrashi, isitshizi. okanye uzicwilise kwisampuli ecocekileyo, kwaye uthelekise umbala kunye nesampuli yoqobo emva kokuba umbala uzinzile. Umgaqo othi "ukusuka ekukhanyeni ukuya kumnyama" kufuneka ubanjwe kuyo yonke inkqubo yokudibanisa umbala.
