Zvinhu zvikuru zvinoita kuti pamusoro peputty isapinda mvura paite yero. Mushure mekutsvagurudza zvinhu, kuyedza kwakawanda uye mainjiniya, munyori anotenda kuti zvinhu zvikuru zvinoita kuti pamusoro peputty isapinda mvura paite yero ndeizvi:
Chikonzero 1. Calcium hydroxide (ash calcium powder) kudzokera kualkali inokonzera yero. Calcium hydroxide, molecular formula Ca (OH) 2, relative molecular weight 74, melting point 5220, pH value ≥ 12, strong alkaline, white fine powder, zvishoma inonyungudika mumvura, inonyungudika muacid, glycerin, shuga, ammonium chloride, inonyungudika muacid kuti ibudise kupisa kwakawanda, relative density i2.24, solution yayo yakajeka yemvura mvura isina ruvara, isina hwema, zvishoma nezvishoma. Inonyungudika, calcium oxide inova calcium carbonate. Calcium hydroxide ine alkaline yakasimba zvine mwero, alkaline yayo uye corrosiveness yayo haina kusimba pane sodium hydroxide, calcium hydroxide uye aqueous solution yayo inoparadza ganda revanhu, zvipfeko, nezvimwewo, asi haina chepfu, uye haifanirwe kusangana zvakananga neganda kwenguva yakareba.
Calcium hydroxide chinhu chinozadza putty isingapindi mvura kuti igadzire firimu rakaoma rine calcium carbonate yakawanda uye upfu hwerabha hwakakora. Nekuda kwealkalinity yayo yakasimba uye huwandu hwakawanda hwealkali, chikamu chemvura iri muputty chichanyudzwa nemadziro panguva yekuvaka. Pasi pemota yesimbi ine alkaline yakasimba, kana pasi pejecha-lime (lime, jecha, simende diki) inonyudzwa, sezvo putty layer inooma zvishoma nezvishoma uye mvura ichipera simba, alkaline zvinhu zviri mumota yevhu neputty uye zvimwe zvacho hazvina kugadzikana mushure me hydrolysis Zvinhu zviri muputty (senge ferrous iron, ferric iron, nezvimwewo) zvichabuda nepaburi diki reputty, uye chemical reaction ichaitika mushure mekusangana nemhepo, zvichiita kuti pamusoro peputty paite yero.
Chikonzero 2. Magasi emakemikari anoshanduka-shanduka. Akadai secarbon monoxide (CO), sulfur dioxide (SO2), benzene, toluene, xylene, formaldehyde, pyrotechnics, nezvimwewo. Mune zvimwe zviitiko zveinjiniya, kwave nemamiriro ezvinhu apo pamusoro peputty pakaita yero nekuda kwekushandiswa kwependi nemoto kuti zvirambe zvichidziya muimba umo putty isingapindi mvura yakangokweshwa, kana kutopisa rusenzi muimba, uye vanhu vazhinji vachiputa panguva imwe chete.
Chikonzero 3. Kukanganiswa kwemamiriro ekunze nezvinhu zvakatipoteredza. Mudunhu rekuchamhembe, panguva yekuchinjana kwemwaka, pamusoro peputty panowanzo shanduka kuita yero kubva muna Mbudzi kusvika Chivabvu wegore rinotevera, asi ichi chinongova chiitiko chakasiyana.
Chikonzero 4. Kufefetera nekuomesa hazvina kunaka. Madziro akanyorova. Mushure mekukwesha putty isingapindi mvura, kana putty layer isina kuoma zvachose, kuvhara magonhi nemahwindo kwenguva yakareba kuchaita kuti pamusoro peputty paite yero zviri nyore.
Chikonzero 5. Matambudziko emidzi yevhu. Pasi pemadziro ekare kazhinji madziro akaita sejecha-grey (raimu, jecha, simende diki, uye mamwe akasanganiswa negypsum). Ishe, asi kuchine nzvimbo dzakawanda uko madziro akaputirwa neraimu neplaster. Zvizhinji zvezvinhu zvemadziro zvine alkaline. Mushure mekunge putty yabata madziro, mvura inotorwa nemadziro. Mushure me hydrolysis uye oxidation, zvimwe zvinhu, zvakaita sealkali nesimbi, zvinobuda nepaburi diki remadziro. Kuitika kwemakemikari kunoitika, zvichiita kuti pamusoro peputty paite yero.
Chikonzero 6. Zvimwe zvinhu. Kuwedzera kune zvinhu zvinogona kuitika zvataurwa pamusoro apa, pachava nezvimwe zvinhu, zvinoda kuongororwa zvakanyanya.
Mhinduro yekudzivirira kuti putty isingapindi mvura isadzoke kuita yero:
Maitiro 1. Shandisa chinhu chinovhara jira kumashure (back-sealing agent) pakuvhara jira kumashure.
Maitiro 2. Pakushongedza madziro ekare, putty yakajairika yemhando yepasi isingapindi mvura uye iri nyore kupwanywa yakambokweshwa kare. Usati washandisa putty yemhando yepamusoro isingapindi mvura, kurapwa kwehunyanzvi kunofanira kutanga kwaitwa. Maitiro acho ndeekuti: tanga wapfapfaidza mvura kuti unyorovese pamusoro pemadziro, uye shandisa spatula kupukuta. Bvisa putty yese yekare woipenda (kusvika pasi pakaoma) woichenesa. Kana madziro aome zvachose, ichenese zvakare woisa chinhu chinobata madziro kuti ufukidze mushonga wekubatidza madziro, wobva wakwesha putty isingapindi mvura.
Nzira 3. Dzivisa magasi emakemikari anoshanduka-shanduka uye mafireworks. Munguva yekuvaka, kunyanya kana putty isina kuoma zvachose mushure mekuvaka, usasvuta kana kubatidza moto mumba kuti udziye, uye usashandise makemikari anoshanduka-shanduka akadai sependi nezvinhu zvinoideredza mukati memwedzi mitatu.
Maitiro 4. Chengeta nzvimbo yacho ine mhepo inofefetera uye yakaoma. Putty isingapindi mvura isati yaoma zvachose, usavhara magonhi nemahwindo zvakasimba, asi vhura mahwindo kuti mhepo ipinde, kuitira kuti putty layer iome nekukurumidza.
Nzira 5. Huwandu hwakakodzera hwe462 modified ultramarine hunogona kuwedzerwa kuputty isingapindi mvura. Nzira chaiyo: Zvichienderana nehuwandu hwe462 modified ultramarine: putty powder = 0.1: 1000, tanga wawedzera ultramarine mumvura yakati wandei, kurunga kuti inyungudike wosefa, wedzera ultramarine aqueous solution nemvura mumudziyo, wobva wadzvanya mvura yese: putty powder = 0.5 : 1 weight ratio, isa putty powder mumudziyo, kurunga zvakaenzana nemuchina wekusanganisa kuti ugadzire mukaka wakakora, wobva waushandisa. Kuedza kunoratidza kuti kuwedzera huwandu hwakati hwe ultramarine blue kunogona kudzivirira pamusoro peputty kuti isashanduke kusvika pamwero wakati.
Maitiro 6. Pakuputira kwave kuyero, mushonga wehunyanzvi unodiwa. Nzira yekurapa ndeye: tanga waisa primer pamusoro peputty, wobva wakwesha woisa putty yepamusoro-soro kana brush yepurasitiki yemadziro.
Pfupikisa pfungwa dziri pamusoro apa:
Kutsvuka kwependi yeporcelain isingapindi mvura pamusoro pevhu uye pendi yeporcelain inotevedzera pendi kunosanganisira zvinhu zvakawanda zvakaita sezvinhu zvakagadzirwa, mamiriro ekunze, mamiriro ekunze, hwaro hwemadziro, tekinoroji yekuvaka, nezvimwewo. Idambudziko rakaoma, uye tsvakiridzo yakawanda nekukurukurirana zvinodiwa.
