Thermosetting Powder Txheej Rau Electrostatic Txau

Daim ntawv ntawm cov hmoov txheej rau electrostatic txau tshuab yog txawv kiag li ntawm cov txheej txheem ib txwm muaj thiab muaj nyob rau hauv lub xeev ntawm cov hmoov zoo. Vim tias tsis muaj cov kuab tshuaj, lawv hu ua hmoov txheej. Cov yam ntxwv tseem ceeb ntawm cov hmoov coatings yog: tsis muaj teeb meem, ua haujlwm zoo, txuag nyiaj txiag thiab ib puag ncig zoo.

Thermosetting hmoov yog ib hom siv electrostatic txau hmoov thiab ib qho ntawm thawj tsim thiab siv. Nws muaj zog hardness, zoo heev tshuaj tiv thaiv thiab zoo heev kub kuj, thiab yog dav siv nyob rau hauv industrial txheej, manufacturing, siv thiab lwm yam teb. Nws yog feem ntau siv thermosetting hmoov xws li epoxy, polyester, acrylate thiab polyether.

Electrostatic txau hmoov txheej feem ntau muab faib ua ob pawg: thermoplastic hmoov txheej thiab thermosetting hmoov txheej.

1. Thermoplastic hmoov txheej

Thermoplastic hmoov txheej muaj cov thermoplastic, pigment, muab tub lim, khi thiab stabilizer. Thermoplastic hmoov txheej muaj xws li: polyethylene, polypropylene, polyester, PVC, chlorinated polyether, polyamide, cellulose, polyester thiab lwm yam.

2. Thermosetting hmoov txheej

Thermosetting hmoov txheej muaj cov thermosetting resin, curing agent, pigment, muab tub lim thiab additives. Thermosetting hmoov txheej muaj xws li: epoxy resin, epoxy polyester, polyester, polyurethane, acrylic resin thiab lwm yam.

Cov hmoov yas tuaj yeem muab faib ua cov hmoov thermoplastic thiab cov hmoov thermosetting; hmoov sab nraum zoov thiab sab hauv tsev hmoov; high-temperature-resistant hmoov thiab tsis tshua muaj kub hmoov.

1. Qhov zoo ntawm cov hmoov yas thermoplastic yog toughness, zoo dabtsi yog khoov, tshuaj tiv thaiv, thiab tuaj yeem siv rau cov txheej txheej ntawm cov yeeb yaj kiab tuab.

2. Qhov zoo ntawm cov hmoov sab hauv tsev yog qhov kev ua haujlwm tsis muaj zog tshaj cov hmoov sab nraum zoov, tuaj yeem siv rau sab hauv tsev ua haujlwm txheej, tus nqi kuj pheej yig.

3. Cov hmoov kub kub tuaj yeem tiv taus qhov kub thiab txias ntawm 200 degrees rau lub sijhawm ntev thiab cov txheej txheem tsis hloov xim, lub cev thiab cov khoom siv hluav taws xob ntawm qhov tso cai ntau yam.

4. Thermosetting hmoov nyob rau hauv chav tsev kub yuav tsis soften thiab agglomeration, zoo mechanical dispersion, yooj yim rau tsim ib tug ca txheej zaj duab xis.

5. Sab nraum zoov hmoov yog tsim rau sab nraum zoov workpiece txheej, nrog antioxidant, anti-ultraviolet ray, anti-acid thiab alkali pos huab thiab nag, thermal expansion thiab contraction kev ua tau zoo.

6. Cov hmoov uas tsis tshua muaj kub muaj peev xwm ua tau rau hauv cov yeeb yaj kiab txheej ntawm 80-150 degrees Celsius, thiab tuaj yeem siv rau ntawm ntoo thiab yas.
