Thaum xaiv cov surfactants rau koj cov tshuaj ntxuav los yog ua cov ntawv thov, ua npuas ncauj yog qhov tseem ceeb. Piv txwv li, nyob rau hauv phau ntawv nyuaj-nto daim ntaub ntawv tu-xws li cov khoom tu tsheb los yog ntxuav tais diav-siab ua npuas ncauj feem ntau yog ib tug zoo tus yam ntxwv. Qhov no yog vim tias muaj cov npuas dej ruaj khov qhia tau tias cov surfactant tau qhib thiab ua nws txoj haujlwm tu. Hloov pauv, rau ntau daim ntawv thov kev lag luam thiab kev ua haujlwm, ua npuas dej tuaj yeem cuam tshuam nrog qee yam kev ua haujlwm tu tshuab thiab inhibit tag nrho kev ua haujlwm. Nyob rau hauv cov ntaub ntawv no, formulators yuav tsum tau siv tsawg-ua npuas ncauj surfactants kom xa cov kev xav tau kev ua tau zoo thaum tswj ua npuas ncauj concentration. Tsab ntawv xov xwm no yog tsim los qhia cov neeg ua npuas ncauj qis, muab qhov chaw pib rau kev xaiv surfactant hauv cov ntawv thov ua npuas dej tsawg.
Low-Foam Applications
Ua npuas ncauj yog tsim los ntawm agitation ntawm huab cua-nto interface. Yog li ntawd, kev tu kom huv uas muaj kev ntxhov siab, kev sib tsoo siab, lossis kev siv tshuab txau feem ntau xav tau surfactants nrog kev tswj kom tsim nyog. Piv txwv xws li: kev ntxhua khaub ncaws, CIP (ntxuav-hauv-qhov chaw) tu, tshuab ntxhua khaub ncaws hauv tsev, ntxhua khaub ncaws ua lag luam thiab kev lag luam, cov kua dej ua haujlwm hlau, cov tshuab ntxhua khaub ncaws ntxhua khaub ncaws, ntxhua khaub ncaws thiab dej haus, thiab lwm yam.
Kev ntsuam xyuas ntawm Low-Foam Surfactants
Kev xaiv ntawm surfactants-los yog kev sib txuas ntawm surfactants-rau kev tswj ua npuas ncauj pib nrog kev ntsuas ua npuas ncauj. Kev ntsuas ua npuas ncauj yog muab los ntawm cov tuam txhab surfactant hauv lawv cov ntaub ntawv khoom siv. Rau kev ntsuas ua npuas ncauj txhim khu kev qha, cov ntaub ntawv yuav tsum ua raws li kev lees paub ua npuas ncauj cov qauv ntsuas.
Ob qhov kev kuaj ua npuas ncauj ntau tshaj plaws thiab txhim khu kev qha yog Ross-Miles ua npuas ncauj kuaj thiab kuaj ua npuas dej siab.
•Ross-Miles Foam Test , ntsuas qhov pib ua npuas ncauj (flash foam) thiab ua npuas ncauj ruaj khov nyob rau hauv qis qis hauv dej. Qhov kev ntsuam xyuas yuav suav nrog kev nyeem cov theem pib ua npuas ncauj, ua raws li cov npuas dej tom qab 2 feeb. Nws tseem tuaj yeem ua tau ntawm qhov sib txawv surfactant concentrations (piv txwv li, 0.1% thiab 1%) thiab qib pH. Feem ntau cov neeg tsim qauv nrhiav kev tswj xyuas ua npuas ncauj qis tsom rau qhov kev ntsuas thawj zaug ua npuas ncauj.
• High-Shear Test (saib ASTM D3519-88).
Qhov kev ntsuam xyuas no sib piv cov ntsuas ua npuas ncauj nyob rau hauv cov av av thiab tsis muaj av. Qhov kev ntsuas siab-shear kuj sib piv qhov pib ua npuas siab qhov siab nrog cov npuas siab tom qab 5 feeb.
Raws li ib qho ntawm cov kev sim saum toj no, ob peb surfactants ntawm kev ua lag luam ua tau raws li cov txheej txheem rau cov khoom xyaw qis. Txawm li cas los xij, tsis hais txoj kev kuaj ua npuas dej tau xaiv, cov khoom ua npuas ncauj qis yuav tsum muaj lwm yam tseem ceeb ntawm lub cev thiab kev ua haujlwm. Nyob ntawm daim ntawv thov thiab kev tu ib puag ncig, lwm yam tseem ceeb rau kev xaiv surfactant yuav suav nrog:
• Kev ua haujlwm huv
• Ib puag ncig, kev noj qab haus huv, thiab kev nyab xeeb (EHS) cov yam ntxwv
• Cov khoom tso tawm av
• Ntau qhov kub thiab txias (piv txwv li, qee qhov ua npuas ncauj qis tsuas yog siv tau thaum kub heev)
• Yooj yim ntawm formulation thiab compatibility nrog lwm cov khoom xyaw
• Peroxide stability
Rau cov neeg tsim khoom, ntsuas cov khoom no nrog rau qib siab ntawm kev tswj ua npuas dej hauv daim ntawv thov yog qhov tseem ceeb. Txhawm rau ua kom tiav qhov sib npaug no, nws yog ib qho tsim nyog yuav tsum sib xyaw cov surfactants sib txawv los daws qhov ua npuas ncauj thiab kev ua haujlwm xav tau - lossis xaiv qis-rau nruab nrab-ua npuas ncauj surfactants nrog kev ua haujlwm dav.
