Momwe Mungachotsere Powder Coating

Njira zambiri zagwiritsidwa ntchito kuchotsa ufa wophimba kuchokera kumakoko opangira, zoyikapo, ndi zosintha.

• Abrasive-media kuphulika
• Mavuni oyaka moto

Kuphulika kwa abrasive-media

Ubwino. Kuphulika kwa abrasive-media ndi njira yodziwika bwino yomwe imagwiritsidwa ntchito pomaliza kuyeretsa ma electro-deposition ndi zokutira zaufa zomwe zimayikidwa pazitsulo. Kuphulika kwa abrasive-media kumapereka kuyeretsa kokwanira ndi kuchotsa zokutira. Chimodzi mwazabwino zotsuka rack ndi abrasive media ndi dzimbiri lililonse kapena oxidation yomwe ingakhalepo imachotsedwa ndi zokutira, ndipo izi zimakwaniritsidwa mozungulira, kapena mchipinda, kutentha.

Zodetsa nkhawa. Kugwiritsa ntchito abrasive media kuyeretsa zoyikapo pafupipafupi kumabweretsa kutaya kwachitsulo. Izi zikutanthauza kuti pakapita nthawi zoyikamo ziyenera kusinthidwa kwathunthu. Chodetsa nkhaŵa china chokhudzana ndi njirayi, ndi chotsalira chowombera chotsalira, ngati sichichotsedwa kwathunthu pazitsulo zingathe kuwononga dothi pakagwiritsidwa ntchito motsatira. Kuphatikiza apo, media abrasive nthawi zambiri imachitika ndi zoyikamo ndikugawira pansi pa chomera, ndikupanga nkhawa zachitetezo. Mtengo wa abrasive-media m'malo uyenera kutengedwa ndi wogwiritsa ntchito.

Mavuni oyaka moto

Ubwino. Njira ya uvuni yoyaka moto imapereka zotsatira zokwanira zochotsera zokutira. Ubwino wa ng'anjo yoyaka moto ndizomwe zimapangidwira pachoyikapo zimatha kudziunjikira kuchokera ku 3 mils mpaka kupitilira 50 mils nthawi zina, ndipo ng'anjo yoyaka moto ikupitilizabe kupereka zotsatira zokwanira zoyeretsa.

Zodetsa nkhawa. Mavuni oyaka moto amagwira ntchito pa kutentha kwa 1,000 ° F kwa maola 1 mpaka 8. Kutentha uku ndi kuyendayenda pakapita nthawi kungayambitse kupsinjika, brittleness, ndi kutopa kwachitsulo pazitsulo zachitsulo. Kuphatikiza apo, phulusa lotsalira lopaka utoto limasiyidwa pachoyikapo pambuyo poyaka moto ndipo liyenera kuchotsedwa ndi kukakamiza madzi kutsuka kapena pickle yamafuta acid kuti mupewe kuipitsidwa. Mtengo wa gasi (mphamvu) kuti ugwiritse ntchito uvuni woyaka moto uyeneranso kutengedwa ndi wogwiritsa ntchito.

Palinso njira ina yochotsera zokutira za ufa zomwe zimagwiritsidwa ntchito pano, ndiko kuchotsa madzi.
