Malunga neDefoamer Defoaming

Kwishishini, ukuba ingxaki yefoam ayithathi indlela echanekileyo, kuya kuba nzima kakhulu ukuyisingatha, ungazamaiarhente yokucoca inxebaKwindlela yokususa i-defoaming, ayilula nje kuphela indlela yokusebenza, kodwa nesiphumo sayo siyabonakala. Okulandelayo, makhe singene nzulu kwiIi-Silicone Defoamersukuze ubone ukuba zingaphi iinkcukacha ongazinanzanga.

Ngexesha lokuveliswa nokusetyenziswa kweengubo, iingxaki zefoam zihlala zisenzeka. Ukuba amasheya awasuswa ngexesha, ukutyibilika kwengubo kuya kuchaphazeleka, okubangela iziphene zomphezulu, ukungalingani, kunye nokuqhekeka ngexesha lokwenziwa kwefilimu, okuya kuthi ekugqibeleni kukhokelele ekunyukeni kweendleko zemveliso. , ngoko ke kufuneka sisebenzise indlela engabizi kakhulu ukusombulula le ngxaki ukuze sibuyisele ilahleko.

Kukho iintlobo ezininzi zee-defoamers, kuquka ioyile yeminerali, i-silicone, kunye ne-polyether, njl.njl., ezineenzuzo ezininzi ezifana nokuzixuba, ukusasazeka lula, ukuguquguquka okunamandla, ukuxubha kakuhle, kunye nokucinywa kwe-foam okuhlala ixesha elide. Konke ngokunye, akuyi kuchaphazela iimpawu zokwenza ifilimu emva kokusetyenziswa, kwaye akuyi kubangela iziphene kumphezulu wepeyinti, ngakumbi kwiinkqubo zepeyinti ezisekelwe emanzini.

Ubungakanani bearhente yokucoca buncinci kakhulu, yi-1000 ukuya kwi-3000 kuphela enokufezekisa isiphumo esicacileyo sokucoca, ngoko ke isetyenziswa kakhulu kwiingubo ezisekelwe emanzini, kwii-inki, kwii-inki, kwii-varnish, kwii-oyile zomphetho wesikhumba, ekwenzeni iphepha, kwiingubo, kwi-laminating glue, kwipeyinti ye-latex, kwii-adhesives nakwezinye iindawo.

Okwangoku, xa kuziwa kwingxaki ye-foam, ezi ndlela zintathu zilandelayo zihlala zisetyenziswa xa kucocwa i-foam.

1. Indlela yokucoca i-foam ngoomatshini

Ukucoca ngoomatshini kudla ngokusetyenziswa kwiimeko apho kufuneka ukufudumeza ukubangela ukonakala kwemveliso kunye nokwahlukana kwefoam, njengaphantsi kotshintsho olukhawulezileyo loxinzelelo, ukwahlukana kwezisombululo kunye nefoams nge-centrifugal, ukutshiza iinkqubo zefoam ngomoya ocinezelweyo, ukuhluza nge-ultrasonic, njl.njl.

2. Indlela yokucoca umzimba

Ngokubanzi, ukucocwa ngokwasemzimbeni kusebenzisa kakhulu indlela yokutshintsha ubushushu bube yi-defoam kunye ne-defoam. Njengoko ubushushu busanda, i-viscosity yesisombululo iyancipha kwaye i-solvent iyaphela, nto leyo ebangela ukuba i-foam iwe. Xa ubushushu buncipha, ukuthamba komphezulu we-foam kuyancipha, kwaye ubushushu obuphantsi bubangela i-icing, nto leyo ephazamisa ulwakhiwo lwe-foam kwaye ibangele ukuba i-foam iqhume.

3. Indlela yokucoca amazinyo ngamakhemikhali

Indlela yokucoca i-chemical defoam ixhomekeke kakhulu ekongezweni kwe-silicone defoam agent, eyindlela elula nesebenzayo yokucoca i-foam kunye ne-antifoaming phakathi kwezi ndlela zintathu. Ixhomekeke kakhulu ekutshintsheni ixabiso le-pH, ukukhupha ityuwa, kunye nokutshintsha indlela esebenza ngayo i-chemical ye-foam. Umgaqo kukuba emva kokuba i-agent yokucoca ifakiwe kwi-agent yokucoca i-foam, ii-molecule zokucoca ziya kusasazwa ngokungacwangciswanga phezu kolwelo, zisasazeke ngokukhawuleza, kwaye zenze ifilimu encinci enezingqimba ezimbini, eya kusasaza ngakumbi, ingene, kwaye ihlasele ngeengqimba, kancinci kancinci ithathe indawo yodonga olubhityileyo lwe-foam yokuqala, ithintele ukwakheka kwefilimu elastiki, itshabalalise amandla okuziphilisa e-foam, kwaye yenze i-foam iqhume.

Ngokweemeko ezahlukeneyo kunye neemfuno ezahlukeneyo zokucoca inkunkuma, khetha indlela yokucoca inkunkuma kunye nearhente yokucoca inkunkuma ekufaneleyo. Singakunika eyona sixhobo sokucoca inkunkuma esifanelekileyo kuwe, wamkelekile ukuba usithenge.
