I-Thermosetting powder coating kanye ne-thermoplastic powder coating
I-Powder enamathela wuhlobo lokumboza 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 ne-filler efomini lokumiswa kwe-liquid. I-coating ngokuvamile isetshenziswa nge-electrostatic bese yelapheka ngaphansi kokushisa ukuze ivumele ukuthi igeleze futhi yakhe "isikhumba". Asetshenziswa njengento eyomile futhi aqukethe okuncane kakhulu, uma ekhona, ama-Volatile Organic Compounds (VOC). Impahla eluhlaza i-literalimpushana, exutshwe eyomile, ekhishiwe, futhi igaywe kwaba okokugcina.Inamathela ephephile endaweni ekwazi ukunikeza izinhlobonhlobo zeziqephu zekhwalithi ephezulu yenza impushana ibe enye indlela ethandwayo esimweni sezulu esibucayi semvelo esiphila kuso namuhla.
Impushana ingaba a i-thermoplastic noma i-thermoset polymer. Ngokuvamile isetshenziselwa ukwakha isiphetho esiqinile esiqinile kunopende ovamile. I-Powder coating isetshenziselwa ikakhulukazi ukumboza izinsimbi, njengempahla yasendlini, i-aluminium extrusions, nezingxenye zemoto nebhayisikili. Ubuchwepheshe obusha buvumela ezinye izinto, njenge-MDF (i-medium-density fibreboard), ukuthi igcotshwe ngempushana kusetshenziswa izindlela ezahlukene.
I-Thermoplastic powder coating ayiphenduli ngamakhemikhali esigabeni sokwelapha. Ngokuvamile zisetshenziselwa izinhlelo zokusebenza ezisebenzayo futhi zisetshenziswa kumafilimu aminyene, ngokuvamile ama-6-12 mils. Zisetshenziselwa uhla olubanzi lwezinhlelo zokusebenza ezidinga isiphetho esiqinile esinokumelana nomthelela kanye/noma ukumelana namakhemikhali.
I-Thermosetting powder coating isetshenziswa bese yelashwa kuhhavini ekushiseni okuthile isikhathi esithile. Inqubo yokwelapha izobangela ukuphambana kwamakhemikhali ukuba kwenzeke, ukushintsha impushana ibe ifilimu eqhubekayo engeke iphinde ibuye.Asetshenziselwa izinhlelo zokusebenza ezihlukahlukene zokusebenza nezokuhlobisa futhi ngokuvamile zisetshenziswa kumafilimu amancanyana, ngokuvamile kugqinsi lefilimu elingu-1.5 kuya ku-4. XNUMX imiz.
