Mokhoa oa ho thibela Powder Coating Caking
Mokhoa oa ho thibela ho apara ka phofo ho baka
Li-resin tse fapaneng tse nang le mocheso o fapaneng oa phetoho ea likhalase, joalo ka epoxy le resin ea polyester e na le mocheso oa phetoho oa khalase o ka bang likhato tse 50 tsa Celsius, sesebelisoa se khantšang (701) se na le mocheso oa khalase o ka bang likhato tse 30 tsa Celsius, moemeli oa boemo ba mokelikeli ka likhato tse tlase tsa Celsius.
Thepa e kholoanyane ea thepa e nang le mocheso o tlase oa phetoho ea likhalase tse entsoeng ka phofshoana ea phofshoana li na le, ho theola mocheso oa phetoho ea khalase e tla fetoha .Mocheso oa phetoho ea likhalase o lekanngoa ka thepa e kholo e inehetseng, bahlahisi ba liphatsa tsa lefutso.ralHa ba na thepa ena e theko e boima, 'me ts'ebetsong ea tlhahiso ha ba khone ho utloisisa mocheso oa phetoho ea khalase ea phofo, ka hona, tlhahiso ea tsamaiso ea phofo e behiloeng ka mocheso oa khalase ea 40 ° C, mocheso oa ho roala phofo. kaka e le mocheso o sireletsehileng. Joale ka tlhahiso ( le ho boloka sehlahisoa le mokhoa oa lipalangoang ) e le mokhoa o tloaelehileng , haufi le ho feta mocheso ona basebetsi ba amehang ba tlameha ho matlafatsa sampling ea sehlahisoa sa caking .Haholo-holo ka Lehlabula, bothata ba ho baka bo hlaha habonolo ka lebaka la mocheso o ntseng o phahama, joale mokhoa oa ho thibela phofo ea ho roala kaka?
Ntlha ea pele, ho roala phofo ka mocheso o itseng oa agglomeration ke molao oa tlhaho. Ho thibela caking phofo barbotage , tlhahiso lokela ho milling , ambalaji, polokelo, lipalangoang, 'me kahoo tshebetso eohle, phofo barbota dihlahiswa ka khalase ea eona phetoho mocheso.
Ho ea ka pono ena ke litharollo tse latelang:
- Tlhahisong ea resin ea polyester, khetho ea mocheso o mong oa phetoho ea khalase e ka eketsa joala kapa acid, kapa ea fokotsa tšebeliso ea resin, mocheso oa phetoho ea khalase ho fokotsa bongata ba joala ho eketsa mocheso oa phetoho ea khalase ea resin ea polyester.
- Ka sebopeho sa phofshoana ea phofshoana ho fokotsa mocheso o tlase oa phetoho ea khalase ea polymer e sebelisoa ka bongata, joalo ka li-agent tsa boemo bo holimo le sesebelisoa sa ho khantša ho netefatsa hore sistimi ea ho roala phofo ha e fokotse mocheso oa phetoho ea khalase.
- Tlhahiso, e robehileng holim'a thepa ea pampiri e lokela ho pholile ka ho lekaneng pele e kena ts'ebetsong ea ho sila, ho sila ho lokela ho ba ho loketseng ho fokotsa sekhahla sa fepa, ho eketsa mocheso oa moea o etellang pele, moea o kenang ho laola ho kenngoa ha mocheso oa moea oa ho sila. Leha ho le joalo, haeba leloala la pele le pshatlehileng li-flakes le khomaretsoe ka holim'a pholileng , ea ho qetela e ne e ke ke ea e-ba le mokhoa oa ho bapala karolo e ntle , nahana ka li-flakes tse sithabetseng ka mokhoa oa ho qobelloa ho pholile ho phekola cryogenic, e sebetsang ho feta ho khutlisetsa morao .
Ho feta moo, li-anti-caking additives li ka eketsoa, tse kang nanosilica (VK-SP15) kapa nano-aluminium oxide (VK-L20M) phofo ho thibela ho khomarela pakeng tsa likaroloana tsa phofo, li-anti-caking agents ke liphatsa tsa lefutso.rally nako e le nngwe le robehileng flakes milling molemo ka ho fetisisa.
Ka kakaretso, tlhahisong, basebetsi ba amehang ba tlameha ho etsa sampole e tiileng ho qoba ho roala phofo.
