Eminyakeni yamuva, ngokuqondiswa kwezinqubomgomo zokuvikela imvelo kanye nokukhuthazwa kwabaningienamathelaabakhiqizi, amanziukuthwalaupende uye waqashelwa ngokwandayo yimakethe, futhi ukusebenza kwezingxenye ezimbili zopende ophuma emanzini kuye kwaqhathaniswa nopende osekelwe kumafutha ezicini eziningi, ezingenakuhlukaniswa nokuthuthukiswa kanye nokusetshenziswaemanzini PUi-ejenti yokwelapha.
I-Bogao's wngemuvaPUi-ejenti yokwelaphaI-BG-2655-80,fnoma okokunamathela emanzini, okunamathelisa amanzi, oyinki abaphuma emanzini, njll.
Ikonaesetshenziswa njengezakhi ze-ejenti yokwelapha ezingxenyeni ezimbili ezitholakala emanziniPUuhlelo.
Inezici zefilimu ye-Paint yokomisa ngokushesha, izakhiwo ezinhle kakhulu zomzimba namakhemikhali.
I-ejenti yokwelapha ye-PU emanzini iqukethe inani elikhulu lamaqembu e-isocyanate (- i-NCO), engafinyezwa ngamaqembu amaningi asebenzayo afana namaqembu e-hydroxyl, amino kanye ne-carboxyl.Indlela yokulawula ngempumelelo ukusabela okuseceleni futhi ulungise upende wezingxenye ezimbili ophuma emanzini ngokusebenza okuhle kakhulu kudinga ukukhetha i-ejenti yokwelapha ephuma emanzini efanele, kanye nokubamba amaphuzu abalulekile omklamo wokuklama nokulungiselela ifilimu ngokuningiliziwe.
Ucwaningo lokusetshenziswa kwe-ejenti yokwelapha ye-PU emanzini lwaqala ekupheleni kwawo-1980.I-Bayer ibihamba phambili ocwaningweni nasekuthuthukisweni, futhi ibe nesandla ekukhuthazeni i-ejenti yokwelapha emanzini kanye nopende ophuma emanzini.Iqale sekwephuzile e-China, kodwa ithuthuke ngokushesha, futhi isetshenziswa kabanzi emigqonyeni yezimboni, i-floor coating, i-wood coatings, imboni yezimoto, imboni yendwangu kanye neminye imikhakha.
- Isicelo in ezinengilazi zezimboni
I-ejenti yokwelapha ye-PU emanzini ifaniswe ne-hydroxyl dispersion resin etholakala emanzini.Ngenxa yokuthi i-hydroxyl dispersion inesisindo esincane samangqamuzana, inani eliphakeme le-hydroxyl futhi ayinayo i-surfactant, inokuminyana okuphezulu, ukuqina okuphezulu, i-gloss enhle kanye nokumelana okuhle ngemva kokuphambana nokuphulukiswa.Ingaqhathaniswa ngokuphelele nezingubo ezisekelwe ngamafutha ekusebenzeni, futhi ingasetshenziswa kabanzi ekulweni nokubola kwezimboni kanye nezingubo zokuhlobisa.
- Isicelo in enamathela floor
Izingxenye ezimbili ze-PU yamanziukugqoka kusetshenziselwa phansi okusekelwe emanzini, okunezici zokuvikela imvelo nempilo.AmanziI-PUukugqoka kunezici zokuguquguquka okuphezulu, ukumelana nokugqoka, ukumelana nesimo sezulu, ukumelana namanzi kanye nokumelana okuhle nokubhala.
- Isicelo ku-Wood Coatings
Upende lwezinkuni ze-matte olusezingeni eliphezulu luyisiqondiso semboni yefenisha.Ifilimu kapende inikeza umuzwa omuhle wokuthungwa ngemva kokushabalala, futhi ithandwa kakhulu ngabantu.I-varnish ehlanganiswe ne-matting agent inokungafihli okuphansi nokumelana okuphansi kokuphakathi.Umthelela wokuhlanganisa ungafinyelelwa nge-ejenti yokwelapha evela esakhiweni samangqamuzana.Uhlobo olufanayo lukapende lwamanzi, olunesakhiwo esihlukile se-matte elaphayo, lungathola isicwebezelisi esisidingayo.
