Lisebelisoa:

• Lipente le Liaparo: Li-defoam tsa phofo li sebelisoa ka lipente tse thehiloeng metsing le tse nang le solvent le liphahlo ho laola ho thehoa ha foam nakong ea ts'ebetso ea tlhahiso, kopo le ho omisa.
• Likhomaretsi le Li-Sealants: Li sebelisoa ka mokhoa oa sekhomaretsi le sealant ho thibela ho bokellana ha foam nakong ea ho kopanya, ho fana le ho sebelisoa.
• Ts'ebetso ea Lik'hemik'hale: Li-defoam tsa phofo li fumana lits'ebetso lits'ebetsong tse fapaneng tsa lik'hemik'hale, joalo ka polymerization, fermentation, le kalafo ea metsi a litšila, ho laola foam le ho ntlafatsa ts'ebetso ea ts'ebetso.
• Lijo le Seno: Indastering ea lijo le lino, li-defoam tsa phofo li sebelisoa ho laola foam ha ho etsoa tšebetso, joalo ka ho ritela, ho belisa le ho paka lijo.
• Masela le Lipampiri: Li sebelisoa ha ho etsoa masela le ho etsa pampiri ho thibela ho bokellana ha foam ha ho daea, ho hatisa, ho koahela le ho etsa boholo.

Tšireletseho le Tšoaro:

• Li-defoam tsa phofo li lokela ho sebetsoa ka hloko, ho latela mehato e nepahetseng ea tšireletso le tataiso e fanoeng ke moetsi.
• Lisebelisoa tsa ho itšireletsa (PPE), tse kang liatlana le likhalase, li lokela ho apesoa ha u tšoara le ho sebelisa li-defoam tsa phofo ho qoba ho kopana ha letlalo le ho hlohlona ha mahlo.
• Ho bohlokoa ho latela litekanyetso tsa litekanyetso tse khothaletsoang le mekhoa ea ts'ebeliso ho fihlela ts'ebetso e nepahetseng ea defoaming ha o ntse o fokotsa litlamorao tse ka bang teng ho boleng ba sehlahisoa le ts'ebetso.

li-powder defoamers ke li-additives tsa bohlokoa lits'ebetsong tse fapaneng tsa indasteri moo taolo ea foam e leng bohlokoa haholo, e fanang ka khatello e sebetsang ea foam, ho e tšoara habonolo le ho feto-fetoha ha maemo ka mokhoa o phofshoana. Ke habohlokoa ho khetha mofuta o nepahetseng le tekanyo ea phofo ea defoamer ho latela litlhoko tse khethehileng tsa kopo le mofuta oa mokhoa oa ho hlahisa foam.
