Ubuchwepheshe be-vacuum evame ukusetshenziswa embonini yamakhemikhali buyi-vacuum degassing. Lokhu kungenxa yokuthi imboni yamakhemikhali ivame ukucubungula ukuxuba nokuvusa izinto ezithile eziwuketshezi eziwuketshezi. Ngesikhathi senqubo, umoya uzohlanganiswa nezinto zokwakha futhi zama-bubble zamafomu. Uma kushiywe kungalashwa, la mabhu bubble azothinta ikhwalithi yomkhiqizo wokugcina. I-vacuum degassing ingayixazulula kahle. Kubandakanya ukucishwa kwesitsha esivaliwe esiqukethe izinto ezingavuthiwe, kusetshenziswa ingcindezi yokunciphisa ama-bubble ngaphakathi kwezinto zokwakha. Kodwa-ke, ngasikhathi sinye njengokuvalelisa, kungaphokopha futhi izinto zokwenziwa eziwuketshezi kumpompo we-vacuum, kubangele ukulimala kwepompo.
Ngakho-ke, kufanele silivikele kanjani ipompo ye-vacuum phakathi nale nqubo? Ake ngihlanganyele icala!
Ikhasimende ngumenzi we-glue odinga ukwenza i-vacuum degassing lapho kuvusa izinto zokwakha uketshezi. Ngesikhathi senqubo evuthayo, izinto ezingavuthiwe zizovalwa futhi zinxuswe kwipompo ye-vacuum. Inkinga ukuthi la magesi azocindezelwa abe yi-liquid resin kanye ne-ejenti yokwelapha! Kubangele ukulimala kwezimpawu zangaphakathi zephampu ye-vacuum nokungcoliswa kwamafutha epompo.
Kuyacaca ukuthi ukuvikela ipompo ye-vacuum, kufanele sivimbele izinto eziluhlaza noma ezivinjelwe ngotshani kusuka ekutholeni iphampu ye-vacuum. Kepha izihlungi ezijwayelekile zokudla zisetshenziselwa kuphela ukuhlunga izinhlayiya ze-powder futhi akukwazi ukufeza lokhu. Yini okufanele siyenze? Eqinisweni, isihlungi sokuthatha sifaka nesihlukanisi segesi-ketshezi, esingahlukanisa uketshezi kugesi, sinembele ngokunembe kakhudlwana, uphinde uthole uketshezi olunamanzi! Ngale ndlela, igesi efakwe ephampu licishe libe yigesi eyomile, ngakho-ke ngeke kulimaze ipompo ye-vacuum.
Leli khasimende lithenge amayunithi ayisithupha ngemuva kokusebenzisa isihlukanisi segesi-liquid, futhi lingacabanga ukuthi umphumela muhle. Ngokwengeziwe, uma isabelomali sanele, kunconywa ukufaka idivaysi ethobisayo, engaluketshezi futhi isuse umphunga wamanzi amaningi ngaphambi kokungena egumbini lokuphampu.
