Ingcaciso yeMveliso
Ipeyinti ye-organic silicon ekwaziyo ukumelana nobushushu obuphezulu, eyaziwa ngokuba yipeyinti ye-high-temperature, ipeyinti ekwaziyo ukumelana nobushushu obuphezulu, yahlulwe yaba yi-organic silicon kunye ne-inorganic silicon ekwaziyo ukumelana nobushushu obuphezulu. Ipeyinti ekwaziyo ukumelana nobushushu obuphezulu, njengoko igama lisitsho, luhlobo lwepeyinti enokumelana ne-oxidation yobushushu obuphezulu kunye nokunye ukubola okuphakathi.
- Ubushushu obuphezulu kwishishini lokugquma ngokubanzi buphakathi kwe-100°C kunye ne-800°C.
- Ipeyinti iyadingeka ukuze kugcinwe iipropati zomzimba ezizinzileyo kwimeko-bume ekhankanyiweyo apha ngasentla: akukho kuxobuka, akukho madyungudyungu, akukho kuqhekeka, akukho mgubo, akukho kugqwala, kwaye ivunyelwe ukuba itshintshe umbala kancinci.
Isicelo seMveliso
Ipeyinti ye-silicon yendalo ekwaziyo ukumelana nobushushu obuphezulu isetyenziswa kakhulu kwiindonga zangaphakathi nezangaphandle zee-blast oven kunye nee-hot blast stoves, ii-chimneys, ii-flues, ii-dry channels, ii-exhaust pipes, ii-hot gas pipes ezishushu ezishushu, ii-heat ovens, ii-heat ex-changers, kunye nezinye iindawo ezingezizo zesinyithi nezesinyithi zokukhusela ubushushu obuphezulu.
Izalathi zokusebenza
- Indlela yovavanyo lwesalathisi seprojekthi
Imbonakalo yefilimu yokupeyinta: ukugqitywa okumnyama okungacwebezeliyo, umphezulu ogudileyo. GBT1729
Ukuqaqamba (iikomityi ezi-4 zokugquma): S20-35. GBT1723 Ixesha lokomisa
Ukomisa itafile kwi-25°C, h < 0.5, ngokuhambelana ne-GB/T1728
Ubushushu obuphakathi kwi-25°C, h < 24
Ukomisa kwi-200°C, h < 0.5
Amandla empembelelo kwi-cm50, ngokuhambelana ne-GB/T1732
Ukuguquguquka kwi-mm, h < 1, ngokuhambelana ne-GB/T1731
Ibanga lokuncamathela, h < 2, ngokuhambelana ne-GB/T1720
I-Gloss, i-semi-gloss okanye i-matte
Ukumelana nobushushu (800°C, iiyure ezingama-24): Ukwaleka kuhlala kuhleli, kwaye utshintsho oluncinci lombala luvumelekile ngokuhambelana ne-GB/T1735
Inkqubo yokwakha
- (1) Ngaphambi konyango: Umphezulu wesiseko kufuneka uphathwe ngesanti ukuze ufikelele kwinqanaba le-Sa2.5;
- (2) Sula umphezulu wento yokusebenza nge-thinner;
- (3) Lungisa i-viscosity yengubo nge-thinner ethile ehambelanayo. I-thinner esetyenzisiweyo yileyo ikhethekileyo, kwaye idosi imalunga: yokutshiza ngaphandle komoya - malunga ne-5% (ngobunzima bokutshiza); yokutshiza ngomoya - malunga ne-15-20% (ngobunzima bokutshiza); yokuxubha - malunga ne-10-15% (ngobunzima bezinto eziphathekayo);
- (4) Indlela yokwakha: Ukutshiza ngaphandle komoya, ukutshiza ngomoya okanye ukuxubha. Qaphela: Ubushushu besiseko ngexesha lokwakha kufuneka bube ngaphezulu kwe-dew point nge-3°C, kodwa bungadluli kwi-60°C;
- (5) Ukucoca ngepeyinti: Emva kokufaka, iya kuphola ngokwendalo kubushushu begumbi kwaye isetyenziswe okanye yomiswe kwigumbi elikwi-5°C kangangeeyure eziyi-0.5-1.0, emva koko ibekwe kwi-oven eyi-180-200°C ukuze ibhakwe iiyure eziyi-0.5, ikhutshwe ize ipholiswe ngaphambi kokusetyenziswa.
Ezinye iiparameter zokwakha: Ubuninzi - malunga ne-1.08g/cm3;
Ubukhulu befilimu eyomileyo (uboya obunye) 25um; Ubukhulu befilimu emanzi 56um;
Incopho yokutsha - 27°C;
Isixa sesicelo sokugquma - 120 g/m2;
Ixesha lokuphumla lokufaka i-coating: iiyure eziyi-8-24 kuma-25°C okanye ngaphantsi, iiyure ezi-4-8 kuma-25°C okanye ngaphezulu
Ixesha lokugcina ipeyinti: Iinyanga ezi-6. Ngaphaya kweli xesha, ingasetyenziswa ukuba iphumelele uhlolo kwaye ifanelekile.
Ixesha leposi: Septemba-10-2025
