Polydimethylsiloxane, nke a makwaara dị ka mmanụ silicone, bụ isi ihe dị na silicone defoamer. Ma e jiri ya tụnyere mmiri na mmanụ nkịtị, nrụgide elu ya pere mpe, nke dabara adaba maka sistemụ ụfụfụ mmiri na sistemụ ụfụfụ mmanụ. Mmanụ silicone nwere nnukwu ọrụ, obere mgbaze, ihe onwunwe kemịkalụ kwụsiri ike, oke ntinye ọkụ, obere mgbanwe, enweghị nsí, na ikike iwepụ ihe. Ihe na-adịghị mma bụ arụmọrụ mgbochi ụfụfụ adịghị mma.

1. Ihe mgbochi ụfụfụ siri ike
Ihe mgbochi siri ike nwere njirimara nke iguzosi ike n'ezi ihe, usoro dị mfe, njem dị mfe na ojiji dị mfe. Ọ dabara adaba maka usoro mmanụ na usoro mmiri, ụdị mgbasa dị n'etiti dịkwa oke mma. A na-ejikarị ya eme ihe n'ọhịa nke obere ụfụfụ ma ọ bụ ntụ ịsa ákwà na-abụghị ụfụfụ.

2. Ihe mgbochi ụfụfụ emulsion
Mmanụ silicone dị na emulsion defoamer nwere nrụgide ka ukwuu, ihe mejupụtara emulsification dịkwa oke ibu. Ozugbo ahọpụtara emulsifier ahụ nke ọma, ọ ga-eme ka ihe mejupụtara defoaming dị larịị ma megharịa n'oge dị mkpirikpi. Nkwụsi ike nke emulsion dị oke mkpa maka ịdị mma nke ihe mejupụtara defoaming. Ya mere, nkwadebe nke ụdị emulsion defoamer silicone lekwasị anya na nhọrọ nke emulsifier. N'otu oge ahụ, emulsion defoamer nwere oke dose na silicone defoamer yana njirimara nke ọnụ ahịa dị ala, oke ngwa sara mbara, mmetụta defoaming doro anya, na ndị ọzọ. Ka teknụzụ nhazi na-aga n'ihu, emulsion defoamer ga-etolite nke ukwuu.

3. Ngwọta Mgbochi Ụfụfụ
Ọ bụ ihe ngwọta e ji agbaze mmanụ silicone n'ime ihe mgbaze. Ụkpụrụ ya nke ịgbaze mmanụ silicone bụ na ihe mgbaze na-ebu ihe mejupụtara mmanụ silicone ma gbasaa ya na mmiri ụfụfụ. N'ime usoro a, mmanụ silicone ga-agbakọta nwayọọ nwayọọ ka ọ bụrụ ntapụ mmiri iji mee ka ọ gbapụ kpamkpam. Enwere ike iji mmanụ silicone agbaze na sistemụ mmiri organic na-abụghị mmiri, dị ka polychloroethane, toluene, wdg, mee ihe dị ka ihe mgbaze mmanụ.

4. Mmanụ Mgbochi Ụfụfụ
Isi ihe dị na mmanụ defoamer bụ mmanụ dimethyl silicone. Mmanụ dimethyl silicone dị ọcha enweghị mmetụta defoamer ma ọ dị mkpa ka e mee emulsification. Nrụgide elu nke silicone emulsified na-ebelata ngwa ngwa, obere ego nwere ike imebi ụfụfụ siri ike ma gbochie ya. Mgbe agwakọtara mmanụ silicone na akụkụ ụfọdụ nke ndị enyemaka silica a na-agwọ hydrophobic, enwere ike ịmepụta defoamer mmanụ. A na-eji silicon dioxide eme ihe dị ka ihe na-ejupụta, n'ihi na nnukwu ìgwè hydroxyl dị n'elu ya nwere ike ime ka ike mgbasa nke mmanụ silicone dịkwuo mma na sistemụ ụfụfụ, mee ka emulsion dịkwuo mma, ma mee ka o doo anya na ọ na-eme ka defoamer silicone dịkwuo mma.

Ebe ọ bụ na mmanụ silicone nwere lipophilic, silicone defoamer nwere mmetụta dị mma na-ebelata mmiri na mmiri na-agbaze na mmanụ. Agbanyeghị, ekwesịrị ịlebara isi ihe ndị a anya mgbe ị na-eji silicone defoamer:

● Ọkpọchi silicone dị ala nwere mmetụta dị mma nke ịgbachi nkịtị, mana ọ naghị adị mma; Ọkpọchi silicone dị elu nwere mmetụta ịgbachi nkịtị nwayọ mana ọ na-adịgide nke ọma.
● Ọ bụrụ na viscosity nke mmiri ọgwụ ụfụfụ dị ala, ọ ka mma ịhọrọ silicone defoamer nke nwere viscosity dị elu. N'ụzọ megidere nke ahụ, ka viscosity nke mmiri ọgwụ ụfụfụ dị elu, ọ ka mma ịhọrọ silicone defoamer nke nwere viscosity dị ala.
● Ibu molekul nke silicone mmanụ nwere mmetụta ụfọdụ na mmetụta ya na-ebelata.
● Defoamer nke nwere obere ibu molekul dị mfe ịgbasa ma gbazee, mana enweghị ntachi obi. N'ụzọ megidere nke ahụ, arụmọrụ defoamer dị elu nke nwere nnukwu ibu molekul adịghị mma, emulsification na-esikwa ike, mana ọ naghị agbaze nke ọma ma ọ na-adịgidekwa.
