Dab tsi yog silicone tiv thaiv

Silicone antifoams yog ib txwm muaj ntawm hydrophobized silica uas tau finely dispersed nyob rau hauv cov kua silicone. Lub resulting compound yog tom qab tsim kom ruaj khov rau hauv cov dej-raws li cov roj-raws emulsion. Cov antifoams no yog ua tau zoo heev vim lawv muaj tshuaj lom neeg ua yeeb yam, muaj ntau yam hauv cov duab ua npuas ncauj qis. Yog tias xav tau, lawv tuaj yeem ua ke nrog lwm cov khoom siv hydrophobic thiab kua los txhim kho lawv cov khoom defoaming.

Silicone antifoam tus neeg ua hauj lwm feem ntau nyiam. Lawv ua haujlwm los ntawm kev rhuav tshem saum npoo nro thiab destabilizing foam npuas, coj mus rau lawv kev vau. Qhov kev ua no pab rau hauv kev tshem tawm sai sai ntawm cov ua npuas ncauj uas twb muaj lawm thiab tseem pab tiv thaiv ua kom muaj kev ua npuas.

Qhov Zoo Ntawm Silicone defosamer

• Muaj ntau cov kev siv

Vim yog cov qauv tshuaj tshwj xeeb ntawm cov roj silicone, nws yog tsis sib xws nrog dej lossis cov tshuaj uas muaj cov pab pawg polarcarbons lossis cov orgrocarbon. Txij li thaum Silicone roj yog insoluble nyob rau hauv ntau cov tshuaj, silicone defosamer muaj ntau cov ntawv thov. Nws tuaj yeem siv tsis tsuas yog rau defoaming dej tshuab, tab sis kuj rau defoaming roj tshuab.

• Cov khoom tsis tshua muaj npoo

Qhov nro ntawm cov roj silicone feem ntau yog 20-21 dynes / cm thiab yog me dua li cov dej nro ntawm cov dej (72 dynes / uas txhim kho cov npuas dej zoo.

• Qhov zoo thermal ruaj khov

Siv cov roj feem ntau txav mus los ua ib qho piv txwv, nws lub sijhawm ntev ntev tuaj yeem siv tau cov neeg sawv cev ua kom ntev li cas tuaj yeem siv hauv qhov ntsuas kub ntau.

• Kev siv tshuaj lom neeg muaj kev ruaj khov

Silicone roj muaj cov tshuaj ruaj khov thiab yog qhov nyuaj los tshuaj ntsuam cov tshuaj nrog lwm yam tshuaj. Yog li ntawd, ntev npaum li kev npaj yog tsim nyog, silicone defoaming cov neeg sawv cev raug tso cai siv cov tshuab muaj kua qaub, thiab ntsev.

• Lub cev inertia

Silicone roj tau ua pov thawj yuav tsis muaj tshuaj lom rau tib neeg thiab tsiaj. Yog li ntawd, silicone defoamers (nrog cov khoom tsis haum uas tsis siv rau pulpment, thiab lwm yam.

• Cov haib defoosing

Silicone defoamers tsis tuaj yeem tsuas yog ua npuas dej tsis txaus ntseeg, tab sis kuj tseem ua npuas ncauj thiab tiv thaiv kom tsim ua npuas ncauj. Qhov ntau npaum li cas yog tsawg heev, thiab tsuas yog ib lab lab (1 ppm lossis 1 g / m3) ntawm qhov hnyav ntawm cov foaming nruab nrab tuaj yeem txuas ntxiv los tsim cov nyhuv defoaming. Nws cov ntau ntau yog 1 txog 100 ppm. Tsis tsuas yog tus nqi qis, tab sis nws yuav tsis ua kom tsis huv cov ntaub ntawv raug kev tiv thaiv.

Silicone antifoams yog muaj nuj nqis rau lawv cov kev ruaj khov, kev sib cav nrog ntau yam tshuaj, thiab ua haujlwm hauv cov kev sib haum xeeb qis. Txawm li cas los xij, nws yog ib qho tseem ceeb kom paub meej tias lawv tau ua raws li cov qauv kev cai thiab haum rau cov ntaub ntawv tshwj xeeb kom tsis txhob muaj kev cuam tshuam zoo rau cov khoom zoo lossis ib puag ncig.
