Ultrasonic Degassing mo e Defoaming 'o e me'a huhu'a

Ko ha founga lelei ʻaupito hono fakaʻaongaʻi ʻo e Degassing mo e defoaming ʻo e viviku ʻi hono fakaʻaongaʻi ʻo e ultrasonic. ʻOku toʻo ʻe Ultrasonication ʻa e fanga kiʻi fuopotopoto kasa siʻisiʻi mei he huhuʻa pea fakasiʻisiʻi ʻa e tuʻunga ʻo e kasa kuo veteki ʻi lalo ʻi he tuʻunga potupotutatau fakanatula.

ʻOku fie maʻu ʻa e degassing mo e defoaming ʻo e viviku ki ha ngaahi taumuʻa lahi, hange ko e ngaahi founga ko ʻeni:

  • sipinga ʻo e teuteu kimuʻa pea toki fua e lahi ʻo e size ke fakaʻehiʻehi mei hono fua ʻo e ngaahi fehalaaki
  • lolo mo e lubricant degassing kimuʻa pea toki pamu ke fakasiʻisiʻi e pamu ʻoku tui koeʻuhi ko e cavitation
  • degassing ʻo e meʻakai huhuʻa, e.g. huhuʻaʻi, sauce pe uaine, ke fakasiʻisiʻi microbial tupulaki mo fakatupulaki e moʻui laupapa
  • degassing ʻo e polymers mo e varnishes kimuʻa pea toki fakaʻaongaʻi, faitoʻo pe vekiume huhuʻi mai lototoʻa

ʻI he taimi ʻoku sonicating ai ʻa e huhuʻa, ko e ngaahi peau lalahi ʻoku propagate mei he feituʻu ʻoku ʻasi ai ʻa e mitia huhuʻa, ʻoku tupu ia mei he ngaahi siakale malohi mo maʻulalo, ʻo makatuʻunga ʻi he tuʻo lahi. Lolotonga e siakale ʻo e ultrasonic, ʻe lava ke faʻu ʻe he ngaahi peau lalahi ha fanga kiʻi fuopotopoto pe voids ʻi he huhuʻa. ʻOku ʻomi ʻe he lahi ʻo e fanga kiʻi fuopotopoto ha feituʻu fuopotopoto maʻolunga. ʻOku tufaki lelei foki mo e bubbles ʻi he huhuʻa. Migrates ʻa e kasa ki he ngaahi fuopotopoto ko ʻeni ʻo fakafou ʻi he feituʻu lahi pea fakalahi ʻa e lahi ʻo e bubbles.
Na'e poupou'i 'a e ngaahi peau ongo e ongo mo e coalescence 'a e leta kakau ve'e tataki ki ha tupulaki vave 'a e leta kakau. 'E toe tokoni foki ke ngalulululu 'a e leta kakau atu 'i he funga vaka he ngaahi peau 'o e sonication mo e fakamalohi'i 'e he leta kakau iiki 'oku malolo 'i lalo he fukahi huhu'a ke tu'u hake 'o fakafou 'i he pea tukuange 'a e kasa entrapped ki he 'atakai.

Tuku ia ki he sivi

ʻE lava ke ʻasi faingofua pe ʻa e founga ʻo e degassing mo e defoaming ʻo e viviku. ʻI ha beaker sioʻata ʻo ha vai ne toki huaʻi hifo, te ultrasonication fakamalohiʻi ʻa e fanga kiʻi fuopotopoto ke coalesce pea vave ʻene ngaʻunu. Te ke lava ʻo sio ki he ola ko ʻeni ʻi he ʻimisi ʻo e fakalakalaka ʻi lalo.

ʻOku ʻi he lolo ʻita ha ngaahi fuopotopoto pe koa kuo tuku hifo. Kae tautautefito ki coolants, ko ha palopalema ʻeni. ʻOku cavitation ai ʻa e ngaahi fuopotopoto kasa ʻoku ne fakaʻaiʻai ʻa e tui ʻi he pamu pe nozzles. ʻOku fakahaaʻi ʻe he ʻimisi ʻo e fakalakalaka ʻi lalo ʻa e ola ultrasonic defoaming.

Ultrasonic degassing is an efficient technique for rapid and effective removal of gases from liquids such as oils, water, solvents etc.

ʻE fakatupu ʻe he Sonication ha fanga kiʻi fuopotopoto siʻisiʻi ʻi he vai mahino mo tolonga. ʻOku fakafonu ʻe he ngaahi fuopotopoto ko ʻeni ʻa e kasa kuo veteki, ʻa ia ʻoku migrates ki he bubbles. Ko ia ai ʻoku tupu mo ngaʻunu ʻa e bubbles. ʻOku ʻasi lelei mai ʻa e ola degassing ʻi ha faʻahinga translucent pe.
ʻI he taimi ʻoku fakalakalaka ai ʻa e fakaʻata ʻi he kiʻi fuopotopoto siʻisiʻi ki he fukahi vai, ʻoku ne fakasiʻisiʻi ʻa e taimi fetuʻutaki ʻi he vahaʻa ʻo e fuopotopoto mo e huhuʻa. ʻI he ʻuhinga ko ʻeni, ʻoku ne fakangatangata ai ʻa e toe fakaleleiʻi ʻo e kasa mei he fuopotopoto ki he huhuʻa. ʻOku matuʻaki tokanga ʻeni ki he ngaahi meʻa viscosity maʻolunga ange, hange ko e lolololo pe resins. Koeʻuhi kuo pau ke hiki ʻa e bubbles ki he fukahi vai, ʻoku ngaue lelei ange ʻa e ultrasonic degassing, kapau ʻoku mamaha ʻa e faʻoʻanga meʻa koeʻuhi ke nounou ange ʻa e taimi ki he fukahi tahi.
