Liaparo tsa polyurea tse sa keneng tsa pente ea polyurea fatše
Tlhaloso ea Sehlahisoa
Liaparo tsa polyurea li entsoe haholo ka likarolo tsa isocyanate le polyether amines. Lisebelisoa tsa hajoale tsa polyurea haholo-holo li na le MDI, polyether polyols, polyether polyamines, amine chain extender, li-additives tse fapaneng tse sebetsang, li-pigments le li-filler, le li-diluent tse sebetsang. Liaparo tsa polyurea li na le litšobotsi tsa lebelo la ho folisa ka potlako, lebelo la kaho le potlakileng, ts'ebetso e ntle ea anti-corrosion le ts'ebetso e sa keneleng metsi, mefuta e mengata ea mocheso le ts'ebetso e bonolo. Li loketse haholo likhoebo tse fapaneng tsa indasteri le tsa merafo, libaka tsa ho paka makoloi, mabala a lipapali, joalo-joalo, bakeng sa ho roala fatše ka litlhoko tsa anti-slip, anti-corrosion and wear resistance.

- 5. Fafatsa polyurea e sa keneleng metsi: Ka mor'a ho hlahloba spray, fafatsa ka tatellano ho tloha holimo ho ea tlase ebe u ea tlaase, u tsamaee sebakeng se senyenyane ka mokhoa oa ho tšela le oa longitudinal. Botenya ba ho roala ke 1.5-2mm. Ho fafatsa ho phethoa ka nako e le 'ngoe. Mekhoa e khethehileng e ka fumanoa ho "Polyurea Engineering Coating Specifications". E phetha karolo ea bohlokoa tabeng ea ho thibela metsi, ha e senyehe ebile ha e thelle.
- 6. Fafatsa/rola sebelisa topcoat e khethehileng bakeng sa polyurea: Kopanya moemeli ea ka sehloohong le moemeli oa ho folisa ka tekanyo, hlohlelletsa hantle, 'me u sebelise rolara e khethehileng ho phutholla seaparo sa polyurea topcoat holim'a polyurea e folisitsoeng ka ho feletseng. E hanela mahlaseli a ultraviolet, e thibela botsofali le ho fetoha ha mebala.
Mokatong oa workshop
- 1. Kalafo ea motheo: Sila lera le phaphametseng holim'a motheo, le pepese sebaka se thata sa motheo. Netefatsa hore motheo o fihla sehlopheng sa C25 kapa ka holimo, o bataletse ebile o omme, o se na lerōle, 'me ha o tsoe lehlabathe hape. Haeba ho na le khekhe ea linotši, libaka tse makukuno, mapetsong, joalo-joalo, joale sebelisa lisebelisoa tsa ho lokisa ho li lokisa le ho li lekanya ho netefatsa hore li tšoarella.
- 2. Polyurea primer kopo: Sebelisa polyurea khethehileng primer evenly motheong ho tiisa pores capillary ka holim'a metsi, ho ntlafatsa mohaho oa fatše, fokotsa mefokolo ho barbotage ka mor'a ho fafatsa, 'me eketsa adhesion pakeng tsa putty polyurea le samente, fatše konkreite. Emela ho fihlela e fola ka botlalo pele o fetela mohatong o latelang oa kaho. Haeba ho na le sebaka se seholo sa ponahalo e tšoeu ka mor'a kopo, e hloka ho sebelisoa hape ho fihlela fatše kaofela ho bonahala e le sootho.
- 3. Polyurea putty kopo: Sebelisa matching polyurea putty khethehileng evenly motheong ho eketsa flatness fatše, tiise pores capillary tse sa bonahaleng ka mahlo a hlobotse, 'me u qobe boemo boo ho fafatsa ea polyurea etsa hore pinholes ka lebaka la ho capillary pores fatše. Emela ho fihlela e fola ka botlalo pele o fetela mohatong o latelang oa kaho.
- 4. Kopo ea polyurea primer: Ho polyurea putty e phekotsoeng, sebelisa polyurea primer ka mokhoa o ts'oanang ho eketsa ka katleho ho khomarela pakeng tsa lera le fafalitsoeng la polyurea le putty ea polyurea.
- 5. Fafatsa kaho ea polyurea: Nakong ea lihora tse 24 ka mor'a hore sehlahisoa se fole, sebelisa lisebelisoa tsa setsebi tsa ho fafatsa ho fafatsa polyurea ka ho lekana. Bokaholimo ba ho roala bo lokela ho ba boreleli, ntle le ho matha, likoti, li-bubble kapa ho phatloha; bakeng sa lits'enyehelo tsa lehae kapa li-pinholes, ho lokisoa ha polyurea ka letsoho ho ka sebelisoa.
- 6. Polyurea topcoat kopo: Ka mor'a hore polyurea holim'a metsi a omelle, sebelisa polyurea topcoat ho thibela botsofali, discoloration, le ho matlafatsa ho hanyetsa ho roala ha polyurea, ho sireletsa lesela la polyurea.
Lisebelisoa tsa merafo
- 1. Metal substrate, sandblasting bakeng sa ho tlosa mafome e fihla SA2.5 standard. Bokaholimo ha bo na lerōle la tšilafalo, litšila tsa oli, joalo-joalo Liphekolo tse fapaneng li etsoa ho latela motheo.
- 2. Primer spraying (ho ntlafatsa ho khomarela ha polyurea motheong).
- 3. Kaho ea ho fafatsa ka polyurea (ka sehloohong se sireletsang lera. Botenya bo khothalletsoa ka kakaretso hore bo be pakeng tsa 2mm le 5mm. Merero e khethehileng ea kaho e fanoa ho latela lihlahisoa tse lumellanang).
- 4. Topcoat brushing / fafatsa mohaho (ba khahlanong le mosehla, ho hanyetsa UV, ho eketsa litlhoko tse sa tšoaneng tsa mebala).
