Kuchotsa thovu ndi mphamvu ya utoto wochotsa thovu lomwe limapangidwa panthawi yopanga ndi kuphimba.Zonyozandi mtundu wa zowonjezera zomwe zimagwiritsidwa ntchito kuchepetsa thovu lomwe limapangidwa popanga ndi/kapena kugwiritsa ntchito zokutira. Ndiye ndi zinthu ziti zomwe zimakhudza kuchotsedwa kwa zokutira?

1. Kukanika kwa pamwamba
Kukanika kwa pamwamba pa chophimba kumakhudza kwambiri chotsukira mpweya. Kukanika kwa pamwamba pa chotsukira mpweya kuyenera kukhala kotsika kuposa kwa chophimbacho, apo ayi sichidzatha kuchotsa thovu ndikuletsa thovu. Kukanika kwa pamwamba pa chophimbacho ndi chinthu chosinthika, kotero posankha chotsukira mpweya, kukanika kosalekeza pamwamba ndi kusinthasintha kwa mphamvu ya pamwamba pa chipangizocho kuyenera kuganiziridwa.

2. Zowonjezera zina
Ma surfactants ambiri omwe amagwiritsidwa ntchito mu zokutira sagwira ntchito bwino ndi ma defoamers. Makamaka, ma emulsifiers, ma wetting and dispersing agents, ma leveling agents, ma thickeners, ndi zina zotero zimakhudza momwe ma defoamers amakhudzira. Chifukwa chake, pophatikiza zowonjezera zosiyanasiyana, tiyenera kusamala za ubale womwe ulipo pakati pa zowonjezera zosiyanasiyana ndikusankha malo abwino olinganiza.

3. Zinthu zochiritsira
Utoto ukayamba kuphikidwa kutentha kwambiri pa kutentha kwa chipinda, kukhuthala kumatsika nthawi yomweyo ndipo thovu limatha kusuntha pamwamba. Komabe, chifukwa cha kusinthasintha kwa chosungunulira, kukhazikika kwa utoto, komanso kuwonjezeka kwa kukhuthala kwa pamwamba, thovu lomwe lili mu utoto lidzakhala lolimba, motero limatsekeka pamwamba, zomwe zimapangitsa kuti mabowo ndi mabowo ang'onoang'ono azichepa. Chifukwa chake, kutentha kwa kuphika, liwiro la kukhuthala, kuchuluka kwa kukhuthala kwa chosungunulira, ndi zina zotero zimakhudzanso mphamvu ya defoaming.

4. Kuchuluka kolimba, kukhuthala, ndi kusinthasintha kwa zokutira
Zophimba zolimba kwambiri, zophimba zokhuthala kwambiri, ndi zophimba zokhuthala kwambiri zonse zimakhala zovuta kwambiri kuchotsa thovu. Pali zinthu zambiri zomwe sizingathandize kuchotsa thovu, monga kuvutika kwa zophimba zokhuthala kufalikira mu zophimba izi, liwiro lochepa la ma microbubbles osanduka ma macrobubbles, kuchepa kwa mphamvu ya thovu kusuntha pamwamba, komanso kukhuthala kwakukulu kwa thovu. Thovu lomwe lili mu zophimba izi ndi lovuta kwambiri kuchotsa, ndipo ndikofunikira kusankha zophimba zokhuthala ndi zophimba zogwiritsira ntchito pamodzi.

5. Njira yophikira ndi kutentha kwa zomangamanga
Pali njira zambiri zogwiritsira ntchito kupaka utoto, kuphatikizapo kutsuka, kupukuta ndi roller, kutsanulira, kukanda, kupopera, kusindikiza pazenera, ndi zina zotero. Mlingo wa thovu la kupaka utoto pogwiritsa ntchito njira zosiyanasiyana zopaka utoto ndi wosiyana. Kupukuta ndi kupaka utoto wozungulira kumapanga thovu lochuluka kuposa kupopera ndi kukanda. Kuphatikiza apo, malo omangira okhala ndi kutentha kwakukulu amapanga thovu lochuluka kuposa lomwe lili ndi kutentha kochepa, koma thovulo limakhala losavuta kulichotsa kutentha kwambiri.
