Udidi: I-Thermoplastic Powder Coating
I-Thermoplastic powder coating iyanyibilika kwaye impompoze xa kufakwa ubushushu, kodwa iyaqhubeka inokwakheka kweekhemikhali ezifanayo xa iqina xa ipholisa. I-Thermoplastic powder coating isekelwe kwii-resin ze-thermoplastic zobunzima obuphezulu be-molecular. Iimpawu zale mpahla zixhomekeke kwiimpawu ezisisiseko ze-resin. Ezi ntlaka ziqinileyo kunye nezixhathisayo zithande ukuba nzima, kwaye zibiza kakhulu, ukuba ziculwe zibe ngamasuntswana amahle kakhulu ayimfuneko ekutshizeni kunye nokuxutywa kweefilim ezincinci. Ngenxa yoko, iisistim ze-thermoplastic resin zisetyenziswa ngakumbi njengezinto zokugquma ezisebenzayo zobukhulu be-mils ezininzi kwaye zisetyenziswa ikakhulu ngobuchule bokusetyenziswa kwebhedi.

Kutheni usebenzisa iingubo ze-thermoplastic?
Iingubo ze-Thermoplastic zibonelela ngokhuseleko olubalaseleyo lwezakhiwo zetsimbi ngokuchasene nokubola, ukuguga kunye nokukrazula kunye nokuhlaselwa kweekhemikhali. Zigqithisa ezinye iingubo, ngakumbi malunga nexesha elide lokuphila, impembelelo yokusingqongileyo kunye nokukwazi ukukhusela isinyithi kumaqondo obushushu ukuya kwi -70 ° C.
Uzisebenzisa njani iiCoatings zePowder ye-Thermoplastic
Indlela yokusebenzisa i-thermoplastic powder coatings ikakhulu ibandakanya: Ukutshiza i-Electrostatic bed process Fluidized bed process Flame Spray technology Electrostatic Spraying Umgaqo osisiseko wale nkqubo kukuba umgubo we-electrostatic ukhokelwa kumphezulu we-workpiece yentsimbi phantsi kwesenzo esidityanisiweyo somoya ocinezelweyo kunye nentsimi yombane. xa udlula kwisithuba esiphakathi kompu wokutshiza kunye nentsimbi esebenza phantsi. Umgubo ohlawulweyo unamathela kumphezulu wentsimbi esebenza phantsi, emva koko unyibilike kwi-Funda ngokugqithisileyo …
Iintlobo zokugquma iiPowder zeThermoplastic
Iintlobo zokugquma umgubo we-Thermoplastic ikakhulu zinezi ntlobo zilandelayo: I-Polypropylene Polyvinyl chloride (PVC) I-Polyamide (iNylon) i-Polyethylene (PE) Izinto eziluncedo kukumelana neekhemikhali ezilungileyo, ukuqina kunye nokuguquguquka, kwaye ingasetyenziswa kwiingubo ezishinyeneyo. Izinto ezingeloncedo yiglosi engalunganga, umgangatho ombi kunye nokuncamathela okulambathayo. Ukuqaliswa okuthe ngqo kweentlobo ze-thermoplastic powder coating: I-Polypropylene powder yokugqoka i-polypropylene powder coating yi-thermoplastic powder emhlophe kunye ne-particle diameter ye-50 ~ 60 mesh. Ingasetyenziswa kwi-anti-corrosion, ipeyinti kunye nezinye iindawo. YiFunda ngokugqithisileyo …
