Lub hauv paus ntsiab lus rau Defoamer Dosage
Kev siv ntau npaum li cas: Qhov pom zoo ntau npaum li cas rau feem ntau cov defoamers yog 0.1% -1% ntawm tag nrho cov kua ntim (Source: *Chemical Engineering Handbook*, 7th Edition). Piv txwv li, 1-10 litres ntawm defoamer yuav tsum tau rau txhua 1 tuj (1,000 litres) kua.
Cov txheej txheem kev tshaj lij: Lub Koom Haum Thoob Ntiaj Teb rau Standardization (ISO) qhia tias ntau npaum li cas hauv qab 0.1% yuav tsis ua haujlwm, thaum tshaj 1% tuaj yeem ua rau muaj teeb meem seem.
Cov hloov pauv tseem ceeb: Kev noj tshuaj yuav tsum tau hloov kho raws li qhov ua npuas ncauj hnyav. Siv 0.1% -0.3% rau cov foaming me me (piv txwv li, tshwm sim los ntawm agitation) thiab 0.5% -1% rau foaming hnyav (xws li, hauv kev lag luam fermentation).
Dosage Adjustments for Specific Scenarios
Kev kho dej khib nyiab: Cov txheej txheem activated sludge feem ntau xav tau 0.05%–0.2% (EPA cov lus qhia); thaum microbial kev ua haujlwm feem ntau ua npuas dej, yuav tsum tau saib xyuas kom tsis txhob muaj kev cuam tshuam cov kab mob microbial.
Kev lag luam khoom noj khoom haus: Rau cov txheej txheem xws li kev tsim cov khoom lag luam kua, qhov ntau npaum li cas yuav tsum tsawg dua lossis sib npaug li 0.01% (GB 2760 Food Safety Standard), thiab zaub mov - qib defoamers yuav tsum tau siv.
Coatings ntau lawm: Kev pom zoo noj ntau npaum 0.3%–0.8% (ASTM D562-2018); Cov nyiaj ntau dhau tuaj yeem ua rau cov khoom ua yeeb yaj kiab.
Qhov tshwm sim ntawm Kev Siv Tsis raug thiab cov lus pom zoo kom zoo
Kev pheej hmoo ntawm kev noj ntau dhau:
Cov nqi nce ntxiv; muaj peev xwm hloov pauv ntawm cov kua viscosity lossis cov khoom ua haujlwm (piv txwv li, txo qis hauv cov txheej txheem).
Cov residue los ntawm qee yam defoamers (xws li silicone- hom) tuaj yeem paug cov khoom.
Kev cuam tshuam ntawm kev siv tsis txaus: Kev ua tsis tiav ntawm kev tshem tawm ua npuas ncauj, ua rau txo qis kev ua tau zoo (piv txwv li, 20% - 30% qeeb hauv kev ua kab nrawm).
Optimization txoj kev:
Me me - ntsuas ntsuas: Pib nrog 0.1% ntau npaum li cas thiab maj mam nce mus txog thaum ua npuas ncauj dissipates.
Kev hloov kho Dynamic: Rau kev tsim khoom tas mus li, kev txhim kho ua npuas ncauj sensors raug pom zoo kom ua kom tsis siv neeg dosing.
