Thermosetting Powder Coating Ukutshiza Electrostatic

Ubume bomgubo wetekhnoloji yokutshiza itekhnoloji ye-electrostatic yahluke ngokupheleleyo kwiingubo eziqhelekileyo kwaye ikhona kwimeko yomgubo ocolekileyo. Ngenxa yokuba i-solvent ingekho, zibizwa ngokuba yi-powder coatings. Iimpawu eziphambili zeengubo zomgubo zezi: azinabungozi, zisebenza kakuhle, zigcina izixhobo kunye nokusingqongileyo.

I-Thermosetting powder luhlobo oluqhelekileyo olusetyenziswayo lwe-electrostatic powder yokutshiza kunye neyokuqala ukuba iphuhliswe kwaye isetyenziswe. Inobulukhuni obuphezulu, ukuchasana kweekhemikhali okugqwesileyo kunye nokumelana nobushushu obuphezulu, kwaye isetyenziswa ngokubanzi kwimizi-mveliso, ukuvelisa, ukwakhiwa kunye nezinye iindawo. Isetyenziswa ngokuqhelekileyo i-thermosetting powders iquka i-epoxy, i-polyester, i-acrylate kunye ne-polyether.

I-Electrostatic spraying powder coatings ngokuqhelekileyo yahlulahlulwe yangamacandelo amabini: i-thermoplastic powder coatings kunye ne-thermosetting powder coatings.

1. I-Thermoplastic powder yokugqoka

I-Thermoplastic powder coating ine-thermoplastic, i-pigment, i-filler, i-binder kunye ne-stabilizer. Iingubo zomgubo ze-Thermoplastic zibandakanya: i-polyethylene, i-polypropylene, i-polyester, i-PVC, i-polyether e-chlorinated, i-polyamide, i-cellulose, i-polyester njalo njalo.

2. Iingubo zomgubo ze-thermosetting

I-Thermosetting powder yokwambathisa iquka intlaka ye-thermosetting, i-ejenti yokunyanga, i-pigment, i-filler kunye ne-additives. I-Thermosetting powder coatings ibandakanya: i-epoxy resin, i-epoxy polyester, i-polyester, i-polyurethane, i-acrylic resin njalo njalo.

I-powder yeplastiki inokwahlulwa ibe ngumgubo we-thermoplastic kunye ne-thermosetting powder; umgubo wangaphandle kunye nomgubo wangaphakathi; umgubo ochasene nobushushu obuphezulu kunye nomgubo ophantsi wobushushu.

1. Iingenelo zomgubo weplastiki we-thermoplastic bukuqina, ukugoba okulungileyo, ukuxhathisa iikhemikhali, kwaye unokufakwa kwi-coating yefilimu yokwambathisa.

2. Inzuzo yepowder yangaphakathi kukuba ukusebenza kubuthathaka kunomgubo wangaphandle, ungasetyenziselwa ukugubungela i-workpiece yangaphakathi, ixabiso lincinci.

3. I-powder yokushisa ephezulu inokumelana nokushisa okuphezulu kwama-degrees angama-200 ixesha elide kwaye isambatho asitshintshi umbala, iimpawu ezibonakalayo kunye nomatshini woluhlu oluvumelekileyo.

4. I-powder ye-thermosetting kwiqondo lokushisa legumbi ayiyi kuthambisa kunye ne-agglomeration, ukusabalalisa okulungileyo komatshini, kulula ukwenza ifilimu yokugqoka flat.

5. I-powder yangaphandle ifanelekile kwi-workpiece yangaphandle, kunye ne-antioxidant, i-anti-ultraviolet ray, i-anti-acid kunye nenkungu ye-alkali kunye nemvula, ukwandiswa kakuhle kwe-thermal kunye nokusebenza kwe-contraction.

6. I-powder ephantsi yobushushu iyakwazi ukulinganisa ifilimu yokugqoka kwi-80-150 degrees Celsius, kwaye ingasetyenziselwa kwimithi kunye neplastiki.
