Pfungwa yekupfapfaidza kwemhepo isina mweya

Kupfapfaidza kusina mhepo kunonzi kunonzi kupfapfaidza kusina mhepo, zvinoreva nzira yekupfapfaidza iyo inoshandisa pombi yeplunger yakakwira kudzvanya pendi kuti iite pendi ine simba repamusoro, nekupfapfaidza kubva mumuromo kuti iite mhepo ine atomi. pamusoro pezvinhu (masvingo kana nzvimbo dzemapuranga).

Kuenzaniswa nemhepo yekupfapfaidza, iyo pendi yepamusoro iyunifomu isina particle kunzwa.Iyo pende yakaoma uye yakachena nekuda kwekuparadzaniswa nemhepo.Airless spraying inogona kushandiswa pakuvaka yakakwirira viscosity pendi, ane yakajeka mipendero, uye kunyange kune mamwe mapurojekiti spraying ane muganhu zvinodiwa.Zvinoenderana nerudzi rwemichina, inogona zvakare kukamurwa kuita pneumatic isina mweya yekupfapfaidza muchina, yemagetsi isina mweya yekupfapfaidza muchina, yemukati yekupisa isina mweya yekupfapfaidza muchina, nezvimwe.

Airless spraying inogona kupatsanurwa inopisa kupfapfaidza mhando, kutonhora kupfapfaidza mhando, electrostatic spraying mhando, mhepo vakabatsira mhando, etc. Kubudirira airless spraying michina uye midziyo yakanyatsobatanidzwa.

(1) Muchikamu chekutanga chekupfapfaidza pasina mweya, pombi yegiya yakashandiswa kudzvanya bhachi, asi kudzvanywa kwacho kwanga kusiri kwakakwira, uye mhedzisiro yeatomization yejasi yaive yakashata pakupisa kwekamuri.Kuti ugadzirise kukanganisa uku, kuvhara kunopisa mberi uye kupfapfaidzwa pasi pekumanikidzwa.Nzira iyi inonzi thermal spraying airless spraying.Nekuda kwehukuru hukuru hwemidziyo, kushandiswa kwayo kunogumira uye hakushandiswe zvakanyanya.

(2) Gare gare, pombi yeplunger yakashandiswa kumanikidza pendi.Kudzvanywa kwependi kwaive kwakakwira, iyo atomization mhedzisiro yaive yakanaka, uye pendi yaisada kudziirwa.Kuvhiya kwacho kwakanga kuri nyore.Nzira iyi inonzi cold spraying airless spraying.Nekupfapfaidza kwakanyanya, kupfapfaidza pendi shoma uye firimu rakakora, inonyanya kukodzera nzvimbo yakakura yekupfapfaidza yemabasa makuru, saka inoshandiswa zvakanyanya.Pahwaro hweizvi, preheat the coating kupfapfaidza yakakwira viscosity coating uye yakakwirira yakasimba coating inogona kuvandudza iyo atomization maitiro, kunatsiridza kushongedza, uye kuwana gobvu firimu.

(3) Electrostatic airless spraying ndiko kusanganisa kwekupfapfaidza kusina mhepo uye kupfapfaidza kwemagetsi, izvo zvinopa kutamba kwakazara kune hunhu hwavo uye zvakanakira uye kunatsiridza kugona kwekupenda.

(4) Zvikamu zviviri zvekupfapfaidza zvisina mhepo inzira itsva yakagadziridzwa kuti ienderane nekupfapfaidza kwezvikamu zviviri zvekupfapfaidza.

(5) Kupfapfaidza kusina mhepo kunobatsirwa nemhepo kunotora zvakanakira kupfapfaidza mhepo kuvandudza kupfapfaidza kusina mweya.Kupfapfaidza kwakadzikira uye kunongoda chete 1/3 yedzvinyiriro yekupfapfaidza kusina mweya.
