Upende we-Waterborne Polyurethane

I-trapezium esekelwe emanzini ekhethekile engenisiwe, isayensi yamakhemikhali kazwelonke, amanzi akhishiwe, izithasiselo ezisekelwe emanzini kanye nesigcwalisi sokuvikela imvelo nezinye izakhi, ayinayo i-benzene, umndeni, i-benzene yezinga lesibili nezinye izincibilikisi eziphilayo.Umkhiqizo ulungiswa ngu kusetshenziswa i-aliphatic polyurethane resin esekwe emanzini njengesisekelo sezinto zokwakha ifilimu, i-HDI njenge-ejenti elaphayo, enezela izigcwalisi ezinobungani bemvelo nezisiza ezisebenzayo. Ifilimu egcwele, isicwebezelisi esiphezulu, umbala ogqamile. Ukunamathela okuhle, ubulukhuni obuphezulu, ukumelana nesimo sezulu esihle kakhulu.

Inkambu yohlelo lokusebenza

Ifanele izidingo eziphakeme, izimfuneko eziphakeme zokumelana nesimo sezulu ze-coating yopende ephezulu. Isetshenziswa kakhulu ekuhlobiseni okungaphezulu kwezingxenye zensimbi ezifana ne-wind power tower barrel, imishini yemishini, imishini yokwakha, ipayipi likawoyela we-petrochemical, njll. Inokumelana nesimo sezulu esihle kakhulu sangaphandle kanye nokumelana nokugqwala.

Ukwelashwa kwendawo

1. Ubuso kufanele buhlanzeke futhi bome, futhi ukwelashwa okungaphezulu kwe-substrate kufanele kuhlangabezane nezidingo.

2. Amathuluzi asetshenziswa ekwakheni kumele ome futhi ahlanzeke. 3.

3. kunqatshelwe ukuthintana ne-asidi ne-alkali ngesikhathi senqubo yokulungisa upende nokugqoka.

4. Isikhathi sokudweba kufanele silawulwe ngokuqinile, lapho izinga lokushisa lingu-25′C, isikhathi sokudweba akufanele sibe ngaphansi kwamahora angu-12.

5. Awukwazi ukupenda ugqinsi, ifilimu ayikwazi ukweqa 40μm noma ngeke bubble.

6. Ukwakhiwa nokomisa nokuphulukisa ngesikhathi somswakama ohlobene awukho mkhulu kuno-75%, izinga lokushisa alikwazi ukuba ngaphansi kuka-0 ℃ C, ngaphandle kwalokho ifilimu ayikwazi ukuphulukiswa ngokuphelele ithonya.
