Isigaba: I-Thermoset Powder Coating
I-Thermosett powder coating isebenzisa inhlaka ye-thermoset njengento eyenza ifilimu, yengeze i-ejenti yokwelapha ukusabela kokuxhumanisa, futhi yakha uqweqwe oluqinile olungancibilikiyo nelingashiki ngemva kokushisisa. Njengoba inhlaka esetshenziswa embotsheni yempushana ye-thermoset iyi-prepolymer enezinga eliphansi le-polymerization, isisindo samangqamuzana siphansi, izinga le-coating lingcono, futhi inomhlobiso ongcono, futhi i-prepolymer ephansi ye-molecular weight ingelapheka ngemva kokwelashwa. . Ama-macromolecules enza inethiwekhi exhumene, ngakho-ke ukugqoka kunokumelana nokugqwala okungcono kanye nezakhiwo zemishini.
I-Thermoset powder coating ingahlukaniswa ngezigaba ezilandelayo:
1.Thermoset polyester powder coatings
2. I-Thermoset epoxy powder coatings
3. I-Thermoset polyurethane powder coatings
4. I-Thermoset epoxy polyester powder coating
Ubuhle:
1. Impilo kanye nokuvikelwa kwemvelo.
Zonke izinhlobo zezithasiselo eziyingozi zamakhemikhali awuketshezi ezengezwe ukuze kufezwe ukusebenza kokumboza, njengokwenza ifilimu, ukusabalalisa, ukumanzisa, ukulinganisa, izithasiselo zokulwa nokugqwala kanye nesikhunta, azifakwanga.
2. Ukuthutha nokubeka izinto kalula
Opende abavamile baqukethe cishe u-20-50% wamanzi noma i-solvent, kuyilapho izimbobo zempushana zingenawo amanzi noma i-solvent, futhi ziqinile ngokuphelele, ezilula futhi eziphephile ukuthuthwa. Ngaphezu kwalokho, izigqoko eziqukethe amanzi noma ama-solvents zingathuthwa futhi zigcinwe emazingeni okushisa aphansi. Ku-0°C, ivamise ukuba yiqhwa, futhi izimbotshana eziyimpushana azinayo le nkinga.
3. Iphunga likapende
Uma kuqhathaniswa nephunga elisele lesakhi sofuzoral upende bendabuko, powder enamathela cishe akukho iphunga.
Okushodayo:
Izimo zokuphulukisa zinemikhawulo ethile.
SEBENZISA INDLELA
I-White Powder Coating Iyathengiswa
Sinempushana emhlophe enamathelayo elandelayo ethengiswayo esitokweni. Futhi singafanisa umbala ngokunembile ngokuya ngesampula yakho. Lelijazi lempushana elinombala omhlophe lingenziwa libe bushelelezi ukuthungwa kwe-matt, umbimbi noma isihlabathi. RAL 9001 Ukhilimu RAL 9002 Okumpunga okumhlophe RAL 9003 Okumhlophe kwesignali RAL 9010 Okumhlophe okumsulwa RAL I-9016 I-Traffic white White Wrinkle Texture I-White Sand Texture White Smooth Matt Ngezinye izinhlobo zempushana enamathela empushana emhlophe, sicela usithinte.
Iyini I-Acrylic Powder Coatings
I-Acrylic powder coating powder inezinto ezinhle kakhulu zokuhlobisa, ukumelana nesimo sezulu, nokumelana nokungcola, futhi inokuqina okuphezulu kwendawo. Ukuvumelana nezimo okuhle. Kodwa intengo iphezulu futhi ukumelana nokugqwala kubi. Ngakho-ke, amazwe aseYurophu generalsebenzisa kahle i-polyester powder ehlanzekile (i-carboxyl-containing resin, yelashwe nge-TGIC); (i-hydroxyl-containing polyester resin yelashwa nge-isocyanate) njenge-powder ukumelana nesimo sezulu. Ukwakheka kwe-Acrylic powder coatings kwenziwa ngama-acrylic resins, pigments and fillers, izithasiselo kanye nama-ejenti okwelapha.

Izakhiwo zeZinc Rich Primer
Izakhiwo ze-Zinc Rich Primer Zinc rich primer iyisistimu yamaphakethe amabili ahlanganiswe ne-metallic zinc ukunikeza ukusebenza okuvelele endaweni egqwala kakhulu. I-Metallic Zinc inika isivikelo se-Cathodic esisekelweni sensimbi futhi amaqembu e-Epoxide asabela nge-polyamide / Amine adduct hardener ukuze enze ifilimu eqinile, engaguquleki ku-ambient temp.Imelana nokonakaliswa kwesithombe ukukhanya kwe-UV njengoba iqukethe i-UV absorber.

I-Thermosetting powder coating isetshenziswa kabanzi kakhulu
I-Thermosetting powder coating isetshenziswa inqubo yokufuthwa kwe-electrostatic, ishisiswe ezingeni lokushisa elidingekayo futhi yelashwe futhi ngokuyinhloko yakhiwe ama-resin ama-molecular weightsolid aphakeme kakhulu kanye ne-crosslinker.Ukwakhiwa kwezimpushana ze-thermosetting kuqukethe ama-resins ayinhloko: i-Epoxy, i-Polyester, i-Acrylic. Lezi zinhlayiya eziyinhloko zisetshenziswa ngama-crosslinkers ahlukene ukukhiqiza izinto ezihlukahlukene zempushana. Ama-crosslinker amaningi, noma ama-ejenti okwelapha, asetshenziswa ekugcokeni okuyimpushana, okuhlanganisa ama-amine, ama-anhydrides, ama-melamine, nama-isocyanate avinjiwe noma angavinjiwe.Ezinye izinto zisebenzisa inhlaka engaphezu kweyodwa ku-hybrid.Funda kabanzi …
I-Thermosetting powder coating kanye ne-thermoplastic powder coating
I-powder coating uhlobo lokugqoka olusetshenziswa njengempushana egelezayo, eyomile. Umehluko omkhulu phakathi kopende olujwayelekile lwe-liquid kanye ne-powder coating yukuthi i-powder coating ayidingi i-solvent ukuze kugcinwe izingxenye ze-binder kanye ne-filler efomini lokumiswa kwe-liquid. I-coating ngokuvamile isetshenziswa nge-electrostatically bese yelashwa ngaphansi kokushisa ukuze ikwazi ukugeleza futhi yenze "isikhumba".
