Hauv cov txheej txheem tsim khoom lag luam ntawm biopharmaceuticals, zaub mov, fermentation, thiab lwm yam, qhov teeb meem ua npuas ncauj uas twb muaj lawm yeej ib txwm yog qhov teeb meem tsis zam. Yog tias muaj ntau cov npuas ncauj tsis raug tshem tawm raws sijhawm, nws yuav coj ntau yam teeb meem rau cov txheej txheem tsim khoom thiab cov khoom zoo, thiab txawm tias ua rau muaj teeb meem khoom siv. Pov tseg, txo qhov ua tau zoo ntawm kev tsim khoom, ua rau lub voj voog tshuaj tiv thaiv ntev dua, txo qhov zoo ntawm cov khoom, thiab lwm yam. Tau kawg, qhov zoo dua ntawm no yog siv cov txheej txheem tshuaj lom neeg defoaming, peb tuaj yeem pom zoo polyether defoamer. Cov defoamer yooj yim siv, pheej yig, sai hauv kev defoaming, zoo hauv kev defoaming nyhuv, thiab ntev hauv lub sijhawm antifoaming, uas feem ntau cov chaw tsim khoom lees txais.
Polyether defoamer feem ntau yog ib qho defoamer muaj zog tau los ntawm kev sib xyaw propylene glycol lossis glycerol nrog propylene oxide, ethylene oxide, thiab lwm yam hauv qab catalysis ntawm potassium hydroxide. Nws yog tus cwj pwm los ntawm kev tiv thaiv ib puag ncig, kev ua haujlwm siab, tsis muaj xim, thiab lwm yam. Nws yog qhov tsim nyog rau cov kev xav tau ntawm feem ntau cov lag luam defoamer tsis muaj silicon xws li defoaming thiab foaming suppression.
Cov yam ntxwv ntawm kev ua tau zoo thiab kev siv
Ua npuas sai thiab siv tsawg dua. Tsis cuam tshuam rau cov yam ntxwv tseem ceeb ntawm lub tshuab ua npuas. Zoo diffusivity thiab nkag mus. Kev ruaj khov tshuaj lom neeg thiab tiv taus oxygen zoo. Tsis muaj kev ua haujlwm ntawm lub cev, tsis muaj tshuaj lom, tsis xeb, tsis muaj kev phiv tshuaj, tsis kub hnyiab, tsis tawg, muaj kev nyab xeeb siab. Hais txog kev siv, yuav tsum ntxiv cov tshuaj ua npuas me me thiab ntau zaus. Cov khoom no tuaj yeem ua kom sov thiab tua kab mob rau hauv lub tank nrog cov tshuaj qub thiab cov khoom siv fermentation, lossis nws tuaj yeem npaj ua dej emulsion, uas ncaj qha mus rau hauv chav sterilized thiab tom qab ntawd "ntxiv dej" rau hauv lub tank rau kev tua npuas. Lub tank npaj cov tshuaj tiv thaiv npuas muaj lub cuab yeej sib xyaw ua ke, yog li cov tshuaj tiv thaiv npuas tuaj yeem tawg tag nrho thiab sib xws, thiab qhov zoo tshaj plaws ntawm kev tua npuas tuaj yeem ua tiav.
Cov Yam Cuam Tshuam Rau Kev Ua Haujlwm ntawm Polyether Defoamer
Cov nyhuv ntawm cov pib sib txawv rau kev ua haujlwm ntawm polyether defoamer, cov nyhuv ntawm cov txheej txheem thaiv sib txawv rau kev ua haujlwm ntawm defoamer, thiab cov nyhuv ntawm cov epoxy ntu sib txawv rau kev ua haujlwm defoaming.
Tau ob peb xyoos dhau los no, peb lub lag luam tau nqus thiab zom cov thev naus laus zis hauv tsev thiab txawv teb chaws. Tib lub sijhawm, peb lub tuam txhab muaj ib pab neeg kws tshaj lij uas mob siab rau pab koj nrog kev nce qib ntawm koj lub Hoobkas silicone defoamer hauv Suav teb, yog tias koj xav paub ntau ntxiv txog cov teeb meem uas peb tuaj yeem daws tau yooj yim rau koj, thov koj xav tiv tauj peb. Peb tos ntsoov yuav tsim kom muaj kev ua tau zoo thiab kev sib raug zoo nrog koj mus sij hawm ntev.
Tsuas yog ob peb xyoos xwb, Cleanwater China Paper Defoamers, Antifoam Agent tau ua rau peb muaj lub koob npe zoo thiab cov kev pabcuam zoo rau cov neeg siv khoom los ntawm kev pabcuam cov neeg siv khoom nrog qhov zoo ua ntej, kev ncaj ncees ua ntej, thiab kev xa khoom sai. Tos ntsoov yuav ua haujlwm nrog koj!
