Hase feela hore e ka bapala karolo ea setso ea ts'ireletso le mokhabiso, hape e fana ka lisebelisoa tse fapaneng tsa mesebetsi e khethehileng, ho kenyelletsa ho kenya letsoho, conductive, anti-tšilafalo, mocheso, lelakabe la mollo, tšireletso ea mahlaseli le mesebetsi e meng.
Nts'etsopele le tlhahiso ea liphahlo tse sebetsang tsa phofo e sa tsoa qala, e ntse e salletse morao haholo le boemo bo tsoetseng pele ba kantle ho naha. Hangata e sebelisoa e sebetsang phofo barbotage liphatsa tsa lefutsoralho na le mefuta e latelang:

Liaparo tsa Powder tse Insulated

Ho roala ha phofo ea insulation Ho sebelisoa ho roala ho khethehileng bakeng sa li-motor, lisebelisoa tsa motlakase le tsa elektroniki, ntle le ts'ireletso ea liphatsa tsa lefutso.ral liphahlo tsa phofo, thepa e khabisitsoeng, empa hape e na le thepa e ntle ea ho kenya motlakase.

Ka ho fetola mofuta oa pheko, kapa ho eketsa modifier e khethehileng le e nang le insulation e ntle le mocheso o hanyetsanang le mocheso oa li-fillers ho lokisa sekhahla sa pheko, se fumanoang ho tloha bonolo haholo, se tenyetseha, se thata haholo. , apara mefuta e sa tšoaneng ea ho roala ho ikamahanya le maemo a fapaneng a ho pata. Lilemong tsa morao tjena, ntle le epoxy phofo barbotage, polyurethane phofo barbotage, phofo barbotage ea polyimide, acrylic phofo barbotage, joalo-joalo le tsona li lula li ntshetsa pele le ho sebelisoa.

Liaparo tsa phofo tse tsamaisang

The conductive phofo barbotage e sebelisoa ho substrate non-conductive, e le hore e na le e itseng conduction hona joale le ho felisoa ha matla electrostatic tsa barbotage tshebetso. Liaparo tse joalo haholo-holo ke mefuta e 'meli: mofuta oa ho kopanya le mofuta oa kahare

Liaparo tsa phofo tse kopantsoeng ke lisebelisoa tsa ho etsa filimi ea polymer, e leng sebopeho seo ho sona ho kenyelletsoang li-fillers tsa conductive. Conductive filler, phofo ea tšepe, joalo ka silevera, nickel, zinki, aluminium, joalo-joalo; eseng-tšepe phofo, tse kang graphite, carbon black; li-oxide tsa tšepe tse kang zinc oxide, antimony oxide. The binder Khetha vinyl resin, polyester resin, polyamide le epoxy resin.

The intrinsic conductive polymer ke polymer ka boeona e ea sebetsa, sehlopha sa hajoale sa polymer se ntse se le molemong oa thuto le lipatlisiso, ha ho na ts'ebeliso e sebetsang.

Ho roala ha phofo ea anticorrosive

Hona joale ho sebelisa liphahlo tse joalo epoxy phenolic anti-corrosion powder e e roala ka epoxy resin le phenolic resin-based based film-forming substances, bobeli ba sefapano se kopanyang sebopeho sa ho roala. Mofuta ona oa pente e sebelisoang ka har'a epoxy ke liphatsa tsa lefutsorally e sebelisoa mefuteng ea polymer ea boima ba limolek'hule ea 1400,2900 le 3570. Epoxy resin ka boeona, ho khomarela, ho feto-fetoha ha maemo le ho hanyetsa alkali le ho molemo, le resin ea phenolic e nang le acid e ntle haholo, solvent, mocheso, mongobo o batang oa ts'ebetso e kopantsoe ho fetoha anti-corrosion. thepa mefuta e loketseng. Reactivity e fokolang lipakeng tsa "epoxy" le "phenolic resin coating film" e hlokahalang maemong a phahameng, ka ho eketsa palo e nepahetseng ea "imidazole" ho fokotsa mocheso o folisang.

Ho roala ha phofo ho thibela mocheso

Ho roala ha phofo ho thibela mocheso nako e telele ho ka mamella mocheso o ka holimo ho 200 ℃, filimi e ntle, 'me ea etsa hore ntho ea tšireletso sebakeng sa mocheso o phahameng o sebetse hantle.

Ho tloha mochine ho latela botsitso ba mocheso oa polymer, ho hanyetsa mocheso oa polymer ho itšetlehile ka sebopeho sa eona sa limolek'hule. Ka hona, eketsa matla a ho sebelisana ha li-intermolecular ka ho kenyelletsa lihlopha tse kholo kapa tse ngata tsa polar ka ketane e kholo, ka tsela eo ho ntlafatsa botsitso ba mocheso oa polymer. Tsela e 'ngoe ke ho ntlafatsa ho hanyetsa mocheso oa litlolo tsa phofo ka ho eketsa li-pigment tse sa keneleng mocheso le li-filler ho polymer. Hangata e sebelisoa ho li-pigment, li-fillers ke phofo ea aluminium, phofo ea mica, phofo ea tšepe e sa hloekang, phofo ea cadmium, silika. Hona joale, seaparo sa phofo se sa keneleng mocheso e ntse e le litlolo tsa silicone tsa phofo tse thehiloeng. Sena se koahela tataiso ea mantlha ea bokhoni ba nts'etsopele ea lipatlisiso nakong e tlang mochesong o phahameng 'me se na le ts'ebetso e ntle ea ho etsa filimi le ts'ebetso ea kaho ea resin e phahameng ea mocheso e le lisebelisoa tsa motheo tsa liphahlo tse thibelang mocheso, hammoho le lipatlisiso li ka ntlafatsa haholo ts'ebetso ea mefuta e fapaneng ea metheo. lintho tse bonahalang maemong a phahameng a mocheso li-pigments, li-fillers, mefuta e mecha.

Ho roala phofo e khabisitsoeng

Lelakabe la phofshoana e thibelang mollo

Ho thibela lelakabe le phahameng la polymer ho thibetsoe, ho ntlafatsa ho lieha ha lelakabe la li-polymer ho bohlokoa haholo libakeng tse ngata tsa ts'ebeliso. Liaparo tsa phofo tse thibelang mollo bakeng sa ts'ebetso ea ho koala mollo le e thibelang mollo. Ka tsoelo-pele e potlakileng ea indasteri ea lisebelisoa tsa elektronike le lisebelisoa tsa morao-rao, litlhoko tsa ho roala mollo o thibelang mollo li potlakile haholoanyane.
