V. Organic Silicon Antifoamer
Ko te Polydimethylsiloxane, e mohiotia ana ko te hinu silicone, ko te waahanga matua o te silicone defoamer. Ki te whakatauritea ki te wai me te hinu noa, he iti ake te maataki o te mata, he pai mo te punaha pahuka wai-wai me te punaha pahuka hinu. Ko te hinu Silicone he mahi nui, he iti te whakarewatanga, he mea matū pumau, he marama te awhe tono, he iti te pähekeheke, he kore-paitini, me te kaha whakaheke. Ko te ngoikoretanga he ngoikore te mahi aukati pahuka.
1. Whakawhanawhara totoka
Ko te Antifoamer Solid nga ahuatanga o te pai o te pumau, o te mahi ngawari, o te kawe waka me te ngawari te whakamahi. He pai mo te waahanga hinu me te waahanga wai, a he mea rongonui ano te momo marara reo. Kei te whakamahia nuitia i roto i te waahi o te pahuka iti, te paura horoi horoi kore ranei.
2. Emulsion Antifoamer
Ko te hinu silicone i roto i te emulsion defoamer he nui ake te taumahatanga, a he nui rawa te whakarea whakaehunga. Ina kowhiria te whakaemulsifier kaore i te tika, ka whakaparahakohia te kaihoko whakakoha me te kaahua i roto i te wa poto. Ko te pumau o te whakaehunga he mea tino nui ki te kounga o te kaihoko whakakore. Na reira, te faaineineraa o te momo whakaehunga silicone defoamer arotahi ki runga i te whiriwhiri o te emulsifier. I te wa ano, ko te whakaehunga defoamer te inenga nui rawa atu i roto i te silicone defoamer me nga ahuatanga o te utu iti, te whanui tono whanui, te kaha o te whakakore, me era atu. Na te ahunga whakamua o te hangarau hanga, ka tino whanake te whakaehunga defoamer.
3. Rongoa Antifoamer
He otinga i hangaia ma te whakakore i te hinu silicone i roto i te whakarewa. Ko tana kaupapa whakaheke ko nga waahanga hinu silicone ka mauhia e te whakarewa ka marara ki roto i te otinga pupuhi. I roto i tenei mahi, ka mimiti haere te hinu silicone ki roto i nga rūrūtia kia oti ai te whakakore. Ko te hinu Silicone kua rewa i roto i te punaha otinga pararopi kore-wai, penei i te polychloroethane, toluene, me etahi atu, ka taea te whakamahi hei whakakore i te wairewa hinu.
4. Hinu Antifoamer
Ko te waahanga matua o te hinu defoamer ko te hinu silicone dimethyl. Ko te hinu dimethyl silicone parakore kaore he painga whakangao me te hiahia kia whakaemulsi. Ka tere te heke o te mata o te silicone emulsified, a ka taea e te iti te pakaru o te pahuka me te aukati. Ka konatunatua te hinu silicone ki etahi ohanga o nga kaiawhina silica hydrophobically tukinotia, ka taea te hanga i te hinu hinu hinu. Ka whakamahia te Silicon dioxide hei whakakii, na te mea he nui nga roopu hydroxyl i runga i tona mata ka taea te whakarei ake i te mana marara o te hinu silicone i roto i te punaha pupuhi, te whakanui ake i te pumau o te whakaehunga, me te tino whakapai ake i nga taonga whakaheke o te silicone defoamer.
Na te mea he lipophilic te hinu silicone, he tino pai te paheketanga o te silicone defoamer ki te otinga hinu-wairewa. Heoi, me aro ki enei tohu ina whakamahi ana i te silicone defoamer:
● iti pokey silicone defoamer he pānga defoaming pai, engari he rawakore tona tohenga; He puhoi te whakakorenga o te silicone pokey defoamer engari he pai te tohe.
● Mēnā he iti ake te pōkākā o te wairewa whakahūka, he pai ake te kowhiri i te kaihoroi silicone me te pokey teitei ake. Engari, ko te teitei ake o te viscosity o te otinga pahuka, he pai ake te kowhiri i te silicone defoamer me te iti ake o te pokey.
● Ko te taumaha irapoo o te hinuhinu silicone defoamer he awe i runga i tona pānga defoaming.
● He ngawari ki te marara me te memeha te kai whakapouri me te taumaha ngota iti, engari te kore o te tohe. I te anga ke, he rawakore te mahi defoaming o tiketike defoamer taimaha rāpoi, a he uaua te emulsification, engari he rawakore te memehatanga he pai te mauroa.
