Ubuchwepheshe be-vacuum obusetshenziswa kakhulu embonini yamakhemikhali i-vacuum degassing. Lokhu kungenxa yokuthi imboni yamakhemikhali ivamise ukudinga ukuxuba nokunyakazisa izinto ezingasetshenzisiwe eziwuketshezi. Phakathi nale nqubo, umoya uzoxutshwa ezintweni ezingavuthiwe futhi wenze ama-bubbles. Uma engelashwa, lawa mabhamuza azophazamisa ikhwalithi yomkhiqizo wokugcina. I-vacuum degassing ingayixazulula kahle. Kubandakanya ukucwenga isiqukathi esivaliwe esiqukethe izinto zokusetshenziswa, usebenzisa ingcindezi ukuze ukhiphe amabhamuza ngaphakathi kwempahla. Kodwa-ke, ngesikhathi esifanayo nokuhlanza, kungase futhi kupompa izinto zokusetshenziswa eziwuketshezi empompini ye-vacuum, kubangele umonakalo epompo.
Ngakho-ke, kufanele siyivikele kanjani ipompo ye-vacuum phakathi nale nqubo? Ake ngihlanganyele icala!
Ikhasimende lingumkhiqizi weglue odinga ukukhipha i-vacuum degassing lapho enyakazisa izinto zokusetshenziswa eziwuketshezi. Ngesikhathi sokunyakazisa, izinto zokusetshenziswa zizohwamuka bese zimuncwa empompini yevacuum. Inkinga ukuthi le gesi izocindezelwa ibe yi-liquid resin kanye ne-ejenti yokwelapha! Kubangele ukulimala kwezimpawu zangaphakathi zepompo ye-vacuum kanye nokungcoliswa kwamafutha epompo.
Kusobala ukuthi ukuze sivikele iphampu yevacuum, kufanele sivimbele izinto zokusetshenziswa eziwuketshezi noma ezihwamukile ukuthi zimunce empompini yevacuum. Kodwa izihlungi ezijwayelekile zokuthatha zisetshenziselwa kuphela ukuhlunga izinhlayiya zempushana futhi azikwazi ukufeza lokhu. Kufanele senzeni? Eqinisweni, isihlungi esithathayo sihlanganisa nesihlukanisi segesi-uketshezi, esingahlukanisa uketshezi kugesi, ngokunembe kakhudlwana, siphinde sincibilikise uketshezi oluhwamukile! Ngale ndlela, igesi efakwe empompini cishe igesi eyomile, ngakho-ke ngeke ilimaze ipompo ye-vacuum.
Leli khasimende lithenge amanye amayunithi ayisithupha ngemva kokusebenzisa isihlukanisi soketshezi lwegesi, futhi kungacatshangwa ukuthi umphumela muhle. Ukwengeza, uma isabelomali sanele, kunconywa ukuthi kufakwe idivayisi yokunciphisa, engakwazi ukucwilisa futhi isuse umhwamuko omningi wamanzi ngaphambi kokungena ekamelweni lepompo.
