Mokhoa oa ho khetha thepa ea ho kenya li-mica board bakeng sa ho etsa li-commutator

commutator mica board, eo hape e bitsoang commutator mica board, ke e 'ngoe ea lisebelisoa tsa bohlokoa ka ho fetisisa tse sireletsang li-motor tsa DC. Ho na le lisebelisoa tse peli tsa mantlha bakeng sa ho etsa commutator mica board: e 'ngoe ke letlapa la mica ea sebaka se senyenyane,' me e 'ngoe ke pampiri ea mica ea phofo. E le ho etsa hore sehlahisoa se fihle botenya bo hlokehang, letlapa la mica le entsoeng ka maqephe a mica le tlameha ho siloa kapa le bentšitsoe. Ha u hatelloa, mahlakoreng a mabeli a kenngoa ka pampiri e fapaneng ea liner le seile, e le hore botenya bo tšoane 'me ho tiisetsoa ka hare ho finyelloa ka mor'a ho hatella. Ha pampiri ea mica ea phofo e sebelisoa ho etsa boto ea mica ea phofo, haeba boemo ba ho hatella bo le botle, mokhoa oa ho sila kapa oa ho sila o ka tloheloa.

Ho phaella moo, ho ea ka maemo a fapaneng a ho kenya letsoho a motlakase, 'me litlhoko tsa anti-arc le ho hanyetsa mongobo, shellac, pente ea polyester, pente ea melamine polyacid, ammonium phosphate aqueous solution, cyclic resin glue kapa pente e fetotsoeng ea silicone e sebelisoa e le likhomaretsi. etsa mefuta e fapaneng ea mapolanka a mica.

Tšebeliso ea shellac e ka hlahisa lipoleiti tsa mica tsa commutator tse ka fihlang mocheso oa 100 ° C le ho feta, ho kenyelletsa le lipoleiti tsa maru a li-commutator bakeng sa li-motor tse lebelo le phahameng. Empa bothata ke hore katleho ea tlhahiso e tlaase.

Ho molemo ho feta shellac ho sebelisa polyacid resin condensed ho tloha ortho-jasmonic anhydride le glycerin. Ho bonolo ho ebola le ho khomarela maqephe a mica, hape e ka iketsetsa mokhoa oa ho hokela maqephe a mica, e le hore palo e kholo ea beng ba matlo e ka hlahisa liboto tsa commutator mica. . Leha ho le joalo, bothata ke hore ho na le resin e sa tsitsang ka har'a boto ea mica, 'me ho tlosoa ha resin ka har'a boto ea mica ho matlafatsoa tlas'a tšusumetso ea mocheso o phahameng le khatello e phahameng. bokahodimo ba sepalangoang sa enjene.

Ha o sebelisa poleiti ea mica ea polyacid resin commutator e le enjene ea mocheso o phahameng ho koala mochini oa crane kapa enjene e kholo, e tlameha ho futhumatsoa pele e sebelisoa. Ka mor'a ho etsa joalo, ha u hatella commutator, ho tsoa ha resin ho tla fokotseha, e leng ho tiisang hore ho tšepahala ha commutator ho sebetsa.

Tšebeliso ea phofo ea Anfu e le sekhomaretsi e ka etsa hore ts'ebetso ea commutator mica board e se fetohe tlas'a maemo a mongobo o phahameng le mocheso (200 ℃ kapa holimo). Sekhahla sa eona sa shrinkage se boetse se nyane ho feta liboto tse ling tsa mica, 'me mocheso oa eona o phahameng oa ho hanyetsa o feta 600 ℃. Ka hona, boleng ba eona ka kakaretso bo phahame ho feta liboto tse fapaneng tsa mica tse boletsoeng ka holimo, 'me mefuta ea ts'ebeliso le eona e pharalletse.

Letlapa la mica le entsoeng ka epoxy kapa melamine le resin ea polyacid e na le khanyetso e ntle ea arc mme e sebelisoa ho li-motors tsa DC tse lebelo haholo.

Boto ea mica e entsoeng ka resin ea tlhaho e fetotsoeng e ka mamella mocheso o phahameng mme e sebelisoa ho li-motors tse khethehileng tsa phallo.

NIDE e fana ka liboto tse fapaneng tsa mica le li-commutators, tse sebelisoang haholo lefapheng la lisebelisoa tsa motlakase, li-brushless motors, li-motor tse ncha tsa motlakase, lisebelisoa tsa ntlo, litafole tse phahamisang, libethe tsa lisebelisoa tsa bongaka le masimo a mang.
