Nzira yekushandisa defoamer pakugadzira mapepa

Mukuita kwekugadzirwa kwemaindasitiri, mafuro akawanda anokuvadza achagadzirwa, uye defoamer inoda kuwedzerwa. Inoshandiswa zvakanyanya kubvisa furo rinokuvadza rinogadzirwa mukugadzirwa kwelatex, machira saizi, kuviriswa kwechikafu, biomedicine, coating, petrochemical, kugadzira mapepa, kuchenesa maindasitiri uye mamwe maindasitiri.Silicone emulsiondefoamer shandisa chinyorwa: usati washandisa kana sampling inoda kumutsa zvizere emulsion. Oiri-mu-mvura emulsion inogona kuderedzwa zvisina tsarukano, asi panguva imwecheteyo, kugadzikana kwe emulsion kuchadererawo zvakanyanya, senge stratification. Paunenge uchinyungudutsa, tapota wedzera mvura kune defoamer uye fambisa zvishoma nezvishoma. Sezvo emulsion ichinyanya kugadzikana pakusangana kwayo kwepakutanga, iyo diluted emulsion inofanirwa kushandiswa mukati menguva pfupi. Emulsions inonzwa uye inonetseka nechando uye tembiricha iri pamusoro pe40°C. Dzivirira kubva kuchando! Mafuta ekuzora akaomeswa nechando anogona kunyatsobviswa muchando, asi anofanira kuongororwa asati ashandiswa. Oscillations yakasimba kana kuveura kwakasimba (zvakadai sekushandisa mechanical pump, homogenizer, etc.) kana kukurudzira kwenguva yakareba kuchaparadza kugadzikana kwemulsion. Kuwedzera viscosity ye emulsion kana kuwedzera thickener kunogona kuvandudza kugadzikana kwe emulsion.

① Inogona kuderedzwa nemvura yakachena 1-3 nguva inodonha mudziva rine slurry, bhokisi rakakwirira, mesh trough uye mamwe mabubble parts; ② Huwandu hwehuputi hwehuputi hwe0.01% -0.2%; ③ chigadzirwa chinofanira kuderedzwa nekukurumidza sezvinobvira munguva pfupi.

Muchigayo chepulp, iyo defoamer inowanzowedzerwa muchikamu chekugezesa nekugeza, uye inowanzowedzerwa mumuchina wekuwachisa pulp, thickener uye pulp tank. The defoamer mubepakugadzira chikamuinowanzowedzerwa kune pepa muchina wekuyerera bhokisi, pulp dziva, coating uye sizing press.

Zvinowanzodhura zvakanyanya kushandisa ma defoamant maviri pane kushandisa yakakwira huwandu hweimwe defoamant, yakawedzerwa yakaparadzana munzvimbo dzakaparadzana. Semuenzaniso, imwe defoamer inowedzerwa pamberi peanorova uye imwe inowedzerwa mubhokisi rekuyerera.
