Muindasitiri, kana dambudziko refuro rikasatora nzira chaiyo, zvichave zvakaoma kubata nazvo, saka unogona kuedza.defoaming agentnokuda kwekusvibisa, kwete chete kushanda kuri nyore, asiwo mhedzisiro yacho iri pachena.Tevere, ngaticherechedzei mukatiSilicone Defoamerskuti uone kuti ingani ruzivo rwawakafuratira.
Munguva yekugadzirwa uye kushandiswa kwejasi, matambudziko efuro anowanzoitika.Kana zvikamu zvikasabviswa munguva, kunyungudika kwejasi kuchakanganiswa, zvichikonzera kukanganisa kwepamusoro, kusaenzana, uye kuputika panguva yekugadzirwa kwemafirimu, izvo zvinozopedzisira zvaita kuti kuwedzerwa mari yekugadzira., saka tinofanira kushandisa nzira isingadhuri kugadzirisa dambudziko iri kuitira kuti tiwanezve kurasikirwa.
Kune marudzi akawanda emadefoam, anosanganisira mineral oil, silicone, uye polyether, nezvimwewo, ane zvakawanda zvakanaka zvakadai se self-emulsification, nyore dispersion, strong versatility, good defoaming, nekugara kwenguva refu furo kudzvanywa.Zvose mune imwe, hazvizokanganisa maitiro ekugadzira mafirimu mushure mekushandiswa, uye hazvizokonzeri kukanganisa pamusoro pepende, kunyanya kumvura-based pendi systems.
Huwandu hwekubvisa furo mumiririri idiki kwazvo, chete churu kusvika kune zviuru zvitatu zvinogona kuita pachena defoaming mhedzisiro, saka inoshandiswa zvakanyanya mumvura-based coatings, ingi, ingi, varnish, ematehwe ematehwe emafuta, papermaking, coating, laminating glue, latex. pendi, zvinonamira nemimwe minda.
Parizvino, kune dambudziko refuro, nzira nhatu dzinotevera dzinowanzo shandiswa pakubvisa furo.
1. Mechanical defoaming nzira
Mechanical defoaming inowanzoshandiswa mumamiriro ezvinhu apo kupisa kunodiwa kukonzera kukanganisa kwechigadzirwa uye kuparadzaniswa kwefuro, senge pasi pekukurumidza kudzvanywa shanduko, kupatsanurwa kwecentrifugal kwemhinduro uye furo, kupfapfaidza furo masisitimu nemhepo yakamanikidzwa, ultrasonic filtration, nezvimwe.
2. Physical defoaming nzira
Kazhinji kutaura, kubvisa furo kwemuviri kunonyanya kutora nzira yekushandura tembiricha kuita defoam uye kudzvinyirira furo.Sezvo kutonhora kunowedzera, viscosity yemhinduro inoderera uye solvent inoputika, zvichiita kuti furo riputsike.Kana tembiricha yadzikira, kunyungudika kwefuro kunoderera, uye tembiricha yakaderera inokonzera icing, izvo zvinokanganisa chimiro chefuro uye chinoita kuti furo riputika.
3. Chemical defoaming nzira
Iyo kemikari yekubvisa furo nzira inonyanya kuvimba nekuwedzera kwesilicone defoaming agent, iri nyore uye inoshanda yekubvisa furo uye antifoaming nzira pakati penzira nhatu idzi.Izvo zvinonyanya kuenderana nekuchinja pH kukosha, salting kunze, uye kushandura kemikari kuita kwefuro.Nheyo yacho ndeyokuti mushure mekunge iyo inosvibisa yawedzerwa kune iyo inobvisa foaming agent, mamorekuru anosvibisa anozogovaniswa zvisina tsarukano pamusoro pemvura, kupararira nekukurumidza, uye kuumba firimu rakatetepa rakapetwa kaviri, iro rinowedzera kupararira, kupinda, uye. pinda muzvikamu, zvishoma nezvishoma Dzorera rusvingo rwakatetepa rwepakutanga furo, kudzivisa kuumbwa kwefirimu elastic, kuparadza kukwanisa kuzviporesa kwefuro, uye kuita kuti furo riputika.
Zvinoenderana neakasiyana mamiriro uye akasiyana ekubvisa furo zvinodikanwa, sarudza nzira yekubvisa furo uye defoaming agent inoenderana newe.Tinogona kukupa iyo yakanyanya kufanira defoamer kwauri, unogamuchirwa kutenga.
