Defoaming ndi kuthekera kwa zokutira kuti athetse chithovu chomwe chimapangidwa panthawi yopanga ndi kuyanika.Zosokonezandi mtundu wa zowonjezera zomwe zimagwiritsidwa ntchito kuchepetsa thovu lomwe limapangidwa panthawi yopanga ndi / kapena kugwiritsa ntchito zokutira. Ndiye ndi zinthu ziti zomwe zimakhudza kupukuta kwa zokutira?

1. Kupsyinjika pamwamba
Kuthamanga kwapamwamba kwa zokutira kumakhudza kwambiri defoamer. Kuthamanga kwapamwamba kwa defoamer kuyenera kukhala kochepa kusiyana ndi zokutira, mwinamwake sikungathe kusokoneza ndi kulepheretsa thovu. Kuthamanga kwapamwamba kwa zokutira ndi chinthu chosinthika, kotero posankha defoamer, kugwedezeka kosalekeza pamwamba ndi kusinthasintha kwapamwamba kwa dongosololi kuyenera kuganiziridwa.

2. Zina zowonjezera
Ma surfactants ambiri omwe amagwiritsidwa ntchito popaka utoto sagwira ntchito ndi ma defoamers. Makamaka, ma emulsifiers, wonyowetsa ndi obalalitsa, othandizira owongolera, zonenepa, ndi zina zambiri zidzakhudza zotsatira za defoamers. Choncho, pophatikiza zowonjezera zosiyanasiyana, tiyenera kumvetsera mgwirizano pakati pa zowonjezera zosiyanasiyana ndikusankha malo abwino.

3. Zinthu zochiritsa
Pamene utoto umalowa mu kutentha kwapamwamba kutentha kutentha, kukhuthala kumatsika nthawi yomweyo ndipo ming'oma imatha kusuntha pamwamba. Komabe, chifukwa cha kusungunuka kwa zosungunulira, kuchiritsa kwa utoto, ndi kuwonjezereka kwa kukhuthala kwa pamwamba, chithovu cha utotocho chimakhala chokhazikika, motero chimatsekeredwa pamwamba, zomwe zimapangitsa kuti mabowo azing'ambika ndi mapini. Choncho, kutentha kuphika, kuchiritsa liwiro, zosungunulira volatilization mlingo, etc. zimakhudzanso defoaming kwenikweni.

4. Zolimba, kukhuthala, komanso kukhazikika kwa zokutira
Zovala zolimba zolimba kwambiri, zokutira zowoneka bwino kwambiri, komanso zokutira zokhathamira kwambiri ndizovuta kwambiri kutulutsa thovu. Pali zinthu zambiri zomwe sizimapangitsa kuti anthu awonongeke, monga kuvutika kwa ma defoamers kufalikira mu zokutira izi, pang'onopang'ono ma microbubbles osandulika kukhala macrobubbles, kuchepa kwa mphamvu ya thovu kusamukira kumtunda, ndi kukhuthala kwakukulu kwa thovu. Chithovu mu zokutira izi n'zovuta kuthetsa, ndipo m'pofunika kusankha defoamers ndi deaerator ntchito osakaniza.

5. Njira yokutira ndi kutentha kwa zomangamanga
Pali njira zambiri zogwiritsira ntchito zokutira, kuphatikizapo kupaka, zokutira zogudubuza, kuthira, kukanda, kupopera mbewu mankhwalawa, kusindikiza pazithunzi, ndi zina zotero. Kupaka thovu kwa zokutira pogwiritsa ntchito njira zosiyana siyana ndizosiyana. Kupaka ndi zokutira zodzigudubuza kumatulutsa thovu kuposa kupopera mbewu ndi kukanda. Kuonjezera apo, malo omangira omwe ali ndi kutentha kwakukulu amatulutsa chithovu chochuluka kusiyana ndi kutentha kochepa, koma chithovucho chimakhalanso chosavuta kuthetsa kutentha kwakukulu.
