Maitiro ekudzivirira Powder Coating Caking
Nzira yekudzivirira powder coating cake
Marezeni akasiyana ane tembiricha yekuchinja kwegirazi, senge epoxy uye polyester resin ine tembiricha yegirazi inosvika makumi mashanu madhigirii Celsius, inovhenekera mumiririri (50) ine tembiricha yegirazi ingangoita makumi matatu madhigirii Celsius, iyo inoyerera yemvura muminus madhigirii Celsius.
Iyo yakakura huwandu hwezvinhu zvine tembiricha yakaderera yegirazi iyo upfu hwekufukidzira maumbirwo ane, iyo yakaderera tembiricha yegirazi inozove .Glass shanduko tembiricha inoyerwa neyakatsaurirwa midziyo yakakura, upfu hwekuputira vagadziri gene.rally havana midziyo inodhura iyi, uye mukugadzira havakwanise kubata tembiricha yegirazi yehupfu, saka, mukugadzirwa kwehupfu hwehupfu hwakamisikidzwa nezve tembiricha yegirazi ye40 ° C, tembiricha yehupfu yekuputira. cakeing as safe temperature . Zvadaro mukugadzirwa ( uye chigadzirwa chekuchengetedza uye chekufambisa maitiro ) sechiyero , pedyo uye pamusoro pekushisa uku vashandi vakakodzera vanofanira kusimbisa sampling yechigadzirwa caking .Especially muZhizha, dambudziko rekiki rinoitika nyore nyore nekuda kwekukwira kwekushisa, zvino sei kudzivirira poda coating cake?
Kutanga, kupfekedza hupfu pane imwe tembiricha agglomeration mutemo wechisikigo. Kudzivirira caking poda coating, kugadzirwa kunofanira kugaya, kurongedza, kuchengetedza, chekufambisa, uye nekudaro maitiro ese, poda yekupotera zvigadzirwa mune yayo tembiricha yegirazi.
Maererano nemaonero aya pane zvinotevera mhinduro:
- Mukugadzirwa kwepolyester resin, kusarudzwa kweimwe tembiricha yegirazi inogona kuwedzera doro kana asidhi, kana kuderedza kushandiswa kweresin, tembiricha yegirazi yekudzikisa huwandu hwedoro kuwedzera tembiricha yegirazi yepolyester resin.
- Muhupfu hwekufukidzira kugadzirwa kudzikisa yakaderera girazi shanduko tembiricha polymer inoshandiswa muhuwandu, senge maajenti ekuyera uye anovheneka ajenti kuti ive nechokwadi chekuti hupfu hwekuputira system haidzikisi tembiricha yegirazi.
- Kugadzirwa, kwakaputsika pamucheka wepepa zvinhu kunofanirwa kutonhodzwa zvakakwana isati yapinda muchigayo, kugaya kunofanirwa kuve kwakakodzera kudzikisa mwero wekudya, kuwedzera inotungamira mweya damper, mhepo yekupinza kudzora kuisirwa kwemhepo yekugaya tembiricha. Zvisinei, kana aimbova chigayo akapwanyika flakes akanamatira atop cooling , iyo yekupedzisira ingadai isina nzira yekuita basa rakanaka , funga yakapwanyika flakes panzira yekumanikidzirwa kutonhora kwe cryogenic treatment, iyo inonyanya kushanda pane retrofitting .
Kupfuurirazve, anti-caking additives inogona kuwedzerwa, senge nanosilica (VK-SP15) kana nano-aluminium oxide (VK-L20M) poda kudzivirira kunamatira pakati pehupfu zvidimbu, anti-caking agents ijeni.rally panguva imwe chete uye akatyoka flakes milling zvakanakisisa.
Zvese mune zvese, Mukugadzira, vashandi vakakodzera vanofanirwa kuita sampling yakasimba kuti vadzivise hupfu hwekuputira kaka.
