Kodi Antifoam ndi chiyani pakugwiritsa ntchito madzi oyipa?

Antifoam, yomwe imadziwikanso kuti defoamer, ndi chowonjezera chamankhwala chomwe chimagwiritsidwa ntchito pochiza madzi oyipa kuti athe kuwongolera kupanga kwa thovu.Chithovu ndi nkhani yofala m'mafakitale opangira madzi oyipa ndipo imatha kuchokera kuzinthu zosiyanasiyana monga organic matter, surfactants, kapena chipwirikiti chamadzi.Ngakhale thovu lingawoneke ngati lopanda vuto, limatha kulepheretsa njira zoyeretsera madzi oyipa posokoneza kagwiritsidwe ntchito ka zida, kuchepetsa mphamvu yamankhwala opangira mankhwala, komanso kupangitsa kuti kusefukira kapena kuchulukirachulukira.

Othandizira antifoam amagwira ntchito posokoneza thovu la thovu, kuwapangitsa kugwa kapena kulumikizana, potero amachepetsa kuchuluka kwa thovu ndikuletsa kusokoneza njira zamankhwala.Mankhwalawa nthawi zambiri amakhala ndi osakaniza a surfactants, mafuta, silicones, kapena zinthu zina za hydrophobic.Akawonjezeredwa kumadzi otayira, antifoam agents amasamukira pamwamba pa chithovu ndikusokoneza kugwedezeka kwa pamwamba, zomwe zimatsogolera kuphulika kwa thovu.

Pali mitundu ingapo ya antifoam agents omwe amagwiritsidwa ntchito pochiza madzi oyipa, iliyonse ili ndi mawonekedwe ake enieni komanso ntchito zake:

Ma antifoam opangidwa ndi silicone:

Izi ndi zina mwazinthu zomwe zimagwiritsidwa ntchito kwambiri ndi antifoam chifukwa chogwira ntchito mosiyanasiyana.Ma antifoam opangidwa ndi silicone ndi okhazikika, osasungunuka m'madzi, ndipo amatha kupangidwa kuti agwirizane ndi njira zosiyanasiyana zochizira madzi oyipa.

Ubwino wa organosilicon defoamers:

Kuchita bwino kwa mankhwala, osachita zinthu zina, kumatha kugwiritsidwa ntchito mu acidic, alkaline, ndi mchere wamchere.

Kukhazikika kwabwino kwa thupi, koyenera kugwiritsidwa ntchito m'mafakitale azakudya ndi zamankhwala, kulibe kuipitsidwa kwa chilengedwe.

Kukhazikika kwamafuta ochepa, kusakhazikika kochepa, ndipo kungagwiritsidwe ntchito pamitundu yosiyanasiyana ya kutentha

Low mamasukidwe akayendedwe, mofulumira kufalikira pa gasi-zamadzimadzi mawonekedwe

Kuthamanga kwapamtunda kumatsika mpaka 1.5-20 mN/m (madzi ndi 76 mN/m)

Osasungunuka mu surfactants ya thovu machitidwe

Mlingo wochepa, kukhuthala kotsika, komanso kupsa mtima kochepa

Ma antifoam a polymeric:

Ma antifoam awa amachokera ku ma polima omwe amasokoneza mapangidwe a thovu potsatsa pamwamba pa thovu la thovu ndikusintha kukhazikika kwawo.Ma polymeric antifoams amagwiritsidwa ntchito nthawi zambiri pomwe mankhwala amtundu wa antifoam sangakhale othandiza, monga m'madzi amchere kapena acidic kwambiri.

Ma antifoam ena:

Nthawi zina, ma antifoam opangidwa ndi silicone sangakhale oyenera chifukwa cha zovuta zaukadaulo kapena zofunikira zinazake.Ma antifoam osakhala a silicone, monga mafuta opangira mafuta amchere kapena mafuta acid-based antifoams, amapereka njira zina zomwe zingakhale zokonda zachilengedwe kapena zoyenera kuzinthu zina.

Antifoams ufa:

Ma antifoam ena amapezeka mu mawonekedwe a ufa, omwe amatha kukhala opindulitsa pakugwiritsa ntchito pomwe zowonjezera zamadzimadzi sizikugwira ntchito kapena pomwe ntchito yayitali ya antifoam ikufunika.

Kusankhidwa kwa wothandizira antifoam woyenera kumadalira zinthu monga momwe madzi akutayira, ndondomeko yeniyeni yogwiritsira ntchito, malamulo oyendetsera ntchito, ndi kulingalira mtengo.Kuphatikiza pa kusankha mankhwala oyenera a antifoam, mlingo woyenera ndi njira zogwiritsira ntchito ndizofunikira kuti zitsimikizire kuwongolera bwino kwa thovu popanda kuwononga magwiridwe antchito amadzi otayira.

Ngakhale antifoam antifoam amatha kuwongolera thovu m'machitidwe opangira madzi oyipa, ndikofunikira kuwagwiritsa ntchito mosamala kuti apewe zotsatira zosayembekezereka monga kusokoneza njira zochizira zamoyo kapena kutulutsa zinthu zovulaza m'chilengedwe.Kuwunika pafupipafupi kuchuluka kwa thovu ndikusintha mlingo wa antifoam ngati pakufunika kungathandize kuwongolera kuwongolera kwa thovu ndikuchepetsa zovuta zilizonse zomwe zingachitike pakugwiritsa ntchito madzi akuwonongeka komanso kutsata chilengedwe.
