Izvo zvakakosha zveyero yepasi peiyo inodzivirira mvura putty Mushure mekutsvaga kwezvinhu, nhamba huru yezviedzo uye maitiro einjiniya, munyori anotenda kuti zvikonzero zvikuru zvekutsvuka kwechiso chemvura inodzivirira putty ndeiyi inotevera. :
Chikonzero 1. Calcium hydroxide (ash calcium powder) kudzokera kune alkali inokonzera yellowing Calcium hydroxide, molecular formula Ca (OH) 2, hama molecular uremu 74, melting point 5220, pH value ≥ 12, alkaline yakasimba, white fine powder, zvishoma Soluble mu mvura, inonyungudika muasidhi, glycerin, shuga, ammonium chloride, inonyungudika muasidhi kuburitsa yakawanda kupisa, hukama hwehukama ndeye 2.24, mhinduro yayo yakajeka yemvura inenge isina ruvara, isina kunhuwa alkaline inoonekera mvura, zvishoma nezvishoma Inotorwa, calcium oxide inova calcium carbonate. Calcium hydroxide ine alkaline yakasimba zvine mwero, alkalinity yayo uye corrosiveness haina kusimba pane sodium hydroxide, calcium hydroxide uye mhinduro yayo ine aqueous inokanganisa ganda remunhu, zvipfeko, nezvimwewo, asi isiri chepfu, uye haifanirwe kusangana neganda. nguva refu.
Calcium hydroxide is an active filler in water-resistant putty kuita firimu rakaoma rine heavy calcium carbonate uye high-gloss rubber powder. Nekuda kweiyo alkalinity yakasimba uye yakakwira alkali yemukati, chikamu chemvura muputty chinotorwa nemadziro emadziro panguva yekuvaka. Iyo yakafanana yakasimba alkaline simende dhaka rezasi, kana jecha-lime pasi (lime, jecha, chidimbu chesimende) inotorwa, sezvo putty layer ichioma zvishoma nezvishoma uye mvura inoputika, zvinhu zvealkali mumatope euswa uye putty uye zvimwe zve. Izvo hazvina kugadzikana mushure me hydrolysis Zvinhu zviri muputty (senge ferrous iron, ferric iron, etc.) zvichabuda kuburikidza nediki. pores of the putty, uye kemikari inogadzirisa ichaitika mushure mekusangana nemhepo, zvichiita kuti pamusoro peputty iite yero.
Chikonzero 2. Volatile organic chemical gases. Zvakadai secarbon monoxide (CO), sulfur dioxide (SO2), benzene, toluene, xylene, formaldehyde, pyrotechnics, etc. Mune dzimwe nyaya dzeinjiniya, pane mamiriro ezvinhu apo putty surface yakashanduka yero nekuda kwekushandiswa kwependi uye moto kuti urambe uchidziya muimba umo iyo inodzivirira mvura putty ichangobva kukweshwa, kana kutopisa rusenzi mumba, uye vanhu vazhinji vachiputa panguva imwe chete.
Chikonzero 3. Kukanganisa kwemamiriro ekunze uye mamiriro ekunze. Munharaunda yekuchamhembe, panguva yekutsinhana kwemwaka, nzvimbo yeputty inowanzoita yero kubva munaNovember kusvika muna Chivabvu wegore rinotevera, asi ichi chingori chiitiko chega.
Chikonzero 4. The ventilation uye kuomesa mamiriro haana kunaka. Rusvingo rwakanyorova. Mushure mekutsvaira putty inodzivirira mvura, kana iyo putty layer isina kuoma zvachose, kuvhara magonhi nemahwindo kwenguva yakareba kuchaita nyore kuti pamusoro peiyo putty iite yero.
Chikonzero 5. Grassroots issues. Pazasi pemadziro ekare kazhinji ijecha-grey madziro (lime, jecha, simende shoma, uye imwe yakasanganiswa negypsum). Ishe, asi kuchine nzvimbo dzakawanda uko madziro akapuramwa neraimu uye plaster. Zvizhinji zvemadziro emadziro ane alkaline. Mushure mekunge putty inobata madziro, imwe mvura inotorwa nemadziro. Mushure me hydrolysis uye oxidation, zvimwe zvinhu, zvakaita sealkali nesimbi, zvinobuda kuburikidza netumaburi tudiki twemudhuri. Kemikari inoitika, zvichiita kuti pamusoro pe putty iite yero.
Chikonzero 6. Zvimwe zvinhu. Mukuwedzera kune pamusoro pezvinogona kuitika, pachava nezvimwe zvinhu, izvo zvinoda kuongororwa zvakare.
Mhinduro yekudzivirira mvura-inodzivirira putty kubva pakudzokera kune yero:
Method 1. Shandisa chisimbiso chemashure chekuvhara shure.
Method 2. Kushongedzwa kwemadziro ekare, iyo yakaderera-giredhi yakajairwa putty iyo isingadzivirirwe nemvura uye iri nyore kupuruzira yakakweshwa kare. Usati washandisa yakakwira-giredhi-inodzivirira mvura putty, kurapwa kwehunyanzvi kunofanirwa kuitwa kutanga. Nzira yacho ndeiyi: kutanga kupfapfaidza mvura kunyorovesa rusvingo pamusoro, uye shandisa spatula kuipukuta Bvisa yose yekare putty uye pendi (kusvikira pasi yakaoma) uye uichenese. Mushure mokunge rusvingo rwaoma zvachose, ruchenese zvakare uye shandisa chigadziro chekutsigira kuti uvhare kurapa kwekutsigira, wozochera putty inodzivirira mvura. yero.
Method 3. Dzivisa kuparara kwemakemikari gasi uye fireworks. Munguva yekuvaka, kunyanya kana iyo putty isati yaoma zvachose mushure mekuvaka, usapfute kana kubatidza moto mukati kuti udziye, uye usashandise makemikari anoputika senge pendi uye akaonda ayo mukati memwedzi mitatu.
Nzira 4. Chengetedza nzvimbo yacho nemhepo uye yakaoma. Pamberi pemvura inodzivirira putty yakaoma zvachose, usavhara magonhi nemahwindo zvakasimba, asi svinura mahwindo emhepo, kuitira kuti putty layer inogona kuoma nokukurumidza.
Nzira 5. Nhamba yakakodzera ye462 yakagadziridzwa ultramarine inogona kuwedzerwa kumvura inodzivirira putty. Yakananga nzira: Zvinoenderana nereshiyo ye462 yakagadziridzwa ultramarine: putty powder = 0.1: 1000, tanga waisa ultramarine mune imwe huwandu hwemvura, kurunga kunyungudika uye kusefa, wedzera ultramarine aqueous solution nemvura mumudziyo, wobva wadzvanya mvura yese: putty poda = 0.5: 1 huremu reshiyo, isa putty poda mumudziyo, kurunga zvakaenzana nemusanganisi kuti uite mukaka wakakora, wozoushandisa. Muedzo unoratidza kuti kuwedzera imwe ultramarine yebhuruu inogona kudzivirira pamusoro peiyo putty kubva kushanduka yero kusvika pamwero wakati.
Nzira 6. Kune putty yakashanduka yero, kurapwa kwehunyanzvi kunodiwa. Iyo yakawanda nzira yekurapa ndeye: tanga waisa primer pamusoro peiyo putty, wozokwesha uye woisa yakakwirira-giredhi remvura inodzivirira putty kana bhurasho remukati memadziro latex pendi.
Pfupisa pfungwa dziri pamusoro apa:
The surface yellowing of water-resistant putty uye kutevedzera porcelain pendi kunosanganisira zvinhu zvakawanda zvakadai sezviwanikwa, mamiriro ekunze, mamiriro ekunze, chigadziko chemadziro, tekinoroji yekuvaka, etc. Idambudziko rakaoma, uye kumwe kutsvakurudza nekukurukurirana kunodiwa.
