1. Ukuphuma kwegumbi lokufafaza ukuze kugcinwe indawo yokusebenza yegumbi lokufutha, isivinini sokungenisa umoya kufanele silawulwe ngaphakathi kwebanga (0.25 ~ 1) m/s ngokuhambisana nezinhlinzeko zomthetho wokuphepha kanye nezempilo. I-exhaust yegumbi lokufutha elijwayelekile ingumthamo womoya omkhulu, ukugcwala komhwamuko oncibilikayo kuphansi kakhulu (ingxenye yawo yevolumu ilinganiselwa ku-10-3% ~ 2×10-'%). Ngaphezu kwalokho, ukukhishwa kwegumbi lokufafaza nakho kuqukethe ingxenye yenkungu kapende ekhiqizwa ngokufafaza.
Usayizi wezinhlayiyana zalolu thuli (amaconsi enkungu ye-lacquer) cishe (20 ~ 200) μm noma ngaphezulu, awukho umoya omkhulu endizela kude, futhi ubangele ingozi yomphakathi eseduze, kodwa futhi ube yisithiyo sokumosha ukwelashwa kwegesi, lezi kufanele zikhokhelwe. ukunaka.
2. Umsebenzi wokukhipha umoya ekamelweni okomisa umoya ekamelweni ukwenza i-coating emdwebeni, ukomisa noma ukomiswa ngenkani ngaphambili, ukuze ingxenye ye-solvent efilimini i-volatilization ebushelelezi kanye nokwakheka kwefilimu enhle, ngokuvamile isandiso se-solvent. inqubo yegumbi lokudweba, kulokhu kukhipha kuqukethe umhwamuko we-solvent kuphela, futhi cishe ayikho inkungu yepende yokufutha.
3. I-exhaust ephuma egumbini lokomisa Igesi ekhishwayo ephuma egumbini lokomisa, okuhlanganisa nokuphuma kwesistimu kapende kanye nesistimu kaphethiloli. Owokuqala uqukethe i-solvent eyinsalela kufilimu enamathelayo engahwamuki egunjini lesifutho nasegunjini lokomisa, ingxenye yezingxenye eziguquguqukayo njenge-plasticizer noma i-resin monomer, imikhiqizo yokubola okushisayo, imikhiqizo yokusabela. Lesi sakamuva sisetshenziswa njengomthombo wokushisa wamagesi okukhipha uphethiloli. Ukubunjwa kwayo kuyahlukahluka ngophethiloli, njengokushisa kwamafutha anzima, aqukethe inani elikhulu lesulfure ekukhiqizeni igesi ye-sulfite, lapho izinga lokushisa lomlilo liphansi, ukulungiswa kokusebenza nokugcinwa okungalungile nokuphathwa, ngenxa yokuvutha okungaphelele nomusi. Ukusetshenziswa kukaphethiloli wegesi, nakuba izindleko zikaphethiloli ziphezulu futhi igesi yokukhipha umlilo icacile, kunezindleko eziphansi zemishini, ukugcinwa okulula, izinzuzo eziphezulu zokusebenza kahle ezishisayo. Lapho ugesi kanye ne-steam kusetshenziswa njengemithombo yokushisa ekamelweni lokumisa, amagesi okukhipha amanzi avela ohlelweni lukaphethiloli awacatshangelwa.
