Umbala oqinile wombala we-pollyurethane topcoat upende ofakiwe

Umbala oqinile wepende polyurethane topcoat upende

Incazelo emfushane:

Upende ezimbili zesakhi, iqembu a lisuselwa ku-resin zokwenziwa njengezinto ezisetshenziswayo, imibala yombala kanye nomenzeli welapha, ne-ejenti ye-polyamide yelapha njengeqembu B.

* Izici zomkhiqizo:

. Ukumelana okuhle kwamakhemikhali nokumelana kwamanzi
. Ukumelana nowoyela wamaminerali, uwoyela wemifino, izixazululo zikaphethiloli neminye imikhiqizo kaphethiloli
. Ifilimu yokupenda inzima futhi icwebezelayo. Ukushisa kwefilimu, hhayi buthaka, hhayi kunamatheli

* Imininingwane yezobuchwepheshe:

* Ukusetshenziswa komkhiqizo:

Isetshenziswa kumaphrojekthi wamanzi ama-Consorvann, amathangi e-crude kawoyela, ukugqwala okujwayelekile kwamakhemikhali, imikhumbi, izakhiwo zensimbi, zonke izinhlobo zezinhlaka zokhonkolo ezingamelana nokukhanya kwelanga.

* Upende wokufanisa:

* Ukwelashwa komhlaba:

Ingaphezulu le-primer kufanele lihlanzeke, lome nokungcola. Sicela unake isikhathi sokuhlangana phakathi kokwakhiwa ne-primer.

* Isimo sokwakha:

Izinga lokushisa elingaphansi kwe-substrate alikho ngaphansi kwama-5 ℃, futhi okungenani ama-3 ℃ aphakeme kunamazinga okushisa we-Air Dew Point, futhi umswakama ohlobene u- <85% (lokushisa kanye nomswakama ohlobene kufanele kulinganiswe eduze kwe-substrate). Ukwakhiwa kwenqatshelwe ngokuphelele inkungu, imvula, iqhwa kanye nesimo sezulu esinomoya.
Ijazi langaphambi kwe-Primer nopende eliphakathi nendawo, bese lomisa umkhiqizo ngemuva kwamahora angama-24. Inqubo yokufafaza isetshenziselwa ukufafaza izikhathi ezingama-1-2 ukufezekisa ubukhulu befilimu obucacisiwe, futhi ubukhulu obunconyiwe bungama-60 μm. Ngemuva kokwakhiwa, ifilimu yokupenda kufanele ibe bushelelezi futhi icaba, futhi umbala kufanele ungaguquguquki, futhi akufanele kube khona ama-sagging, afihlekile, amakhasi e-orange kanye nezinye izifo.

* Amapharamitha wokwakha:

Isikhathi sokuvula: imizuzu engama-30 (23 ° C)

Isikhathi sokuphila:

Lokushisa, ℃	5	10	20	30
Isikhathi Sokuphila (H)	10	8	6	6

Umthamo omncane (isilinganiso sesisindo):

Ukufafaza okungenamoya	Ukufafaza komoya	Brush noma ukugoqa coating
0-5%	5-15%	0-5%

Ukubuyisa isikhathi (ubukhulu befilimu ngayinye eyomile 35um):

Izinga lokushisa le-ambient, ℃	10	20	30
Isikhathi esifushane kunazo zonke, h	24	16	10
Isikhathi eside kunazo zonke, usuku	7	3	3

* Indlela yokwakha:

Ukufafaza: Ukufafaza komoya noma ukufafaza komoya. Kunconywe ukusetshenziswa kwengcindezi ephezulu yokufafaza.
I-Brush / roll coating: Kufanele uzuze ubukhulu befilimu elomile ebekiwe.

* Izinyathelo zokuphepha:

Sicela unake zonke izimpawu zokuphepha epakishe ngesikhathi sokuhamba, ukugcinwa nokusetshenziswa. Thatha izindlela zokuvimbela nokuvikela umlilo ezidingekayo, ukuvimbela umlilo, ukuvikelwa kokuqhuma nokuvikelwa kwemvelo. Gwema ukuphefumula kwama-solvent Vapors, gwema ukuxhumana nesikhumba namehlo ngopende. Musa ukugwinya lo mkhiqizo. Uma kwenzeka ingozi, funa ukwelashwa ngokushesha. Ukulahlwa kukadoti kufanele kube ngokuya ngemithetho yezokuphepha kahulumeni kazwelonke neyasekhaya.
