Silicone Defoamer: Oyang'anira Chete Kulimbana ndi Foam Yamakampani

Chabwino, tiyeni tiyankhule za silicone defoamer. Monga munthu yemwe wakhala akuzama mumipangidwe yamankhwala kwanthawi yayitali 25 zaka, okhazikika mu ma antifoam opangidwa ndi silicone, Ndawona zodabwitsa zazing'onozi zikusintha chisokonezo chamakampani kukhala ntchito zosalala nthawi ndi nthawi. Iwo si mtundu wa chinthu chomwe chimagwira mitu, koma m'minda ngati kuthira madzi oipa, kukonza chakudya, kapena kupanga utoto, ndiwo opulumutsa moyo mtheradi. Ndapanga zambiri mwa izi kwa makasitomala omwe akukumana ndi maloto owopsa, ndipo zotsatira zake sizimalephera kusangalatsa. M'nkhaniyi, Ndikuphwanya zomwe silicone defoamers ndi, momwe amachitira matsenga awo, ubwino wawo waukulu, mapulogalamu ena adziko lenileni, zovuta zomwe zingatheke, ndi kumene teknoloji ikupita. Ngati mukulimbana ndi ming'oma yosalekeza muzochita zanu, izi zitha kungokupatsani malingaliro atsopano.

Choncho, kwenikweni ndi silicone defoamer? Pamtima pake, ndi antifoaming wothandizira womangidwa mozungulira ma silikoni, Nthawi zambiri, polydimethylsiloxane (PDMS). Uwu ndi mtundu wamafuta a silikoni omwe ali hydrophobic - kutanthauza kuti amathamangitsa madzi - ndipo amakhala otsika kwambiri.. Kuti zitheke, nthawi zambiri timasakaniza tinthu ta silika kapena zosintha zina zomwe zimathandizira kumwaza ndi kutsata thovu. Mosiyana ndi mafuta osavuta opangira mafuta, ma silicones amapangidwa kuti azilondola, kupereka kuwongolera kwanthawi yayitali popanda kufunikira kubwereza pafupipafupi. Ndimakumbukira gulu langa loyamba m'ma 90s; inali yoyambira PDMS emulsion, koma ngakhale pamenepo, idapambana china chilichonse pakuyesa kutentha kwambiri.

Phokoso lingamveke ngati laling'ono, koma mu mafakitale, ndi mutu waukulu. Zimamera pamene mpweya kapena mpweya watsekeredwa muzamadzimadzi, okhazikika ndi surfactants monga sopo kapena mapuloteni. Ganizirani za malo opangira moŵa komwe kuwira kwa yisiti kumayambira, kapena chomera chamankhwala komwe kusakaniza kumapanga thovu lomwe limachepetsa mizere yodzaza. M'madzi oipa, mpweya wochizira wachilengedwe umatulutsa okosijeni komanso kukwapula thovu kuchokera ku zotsukira ndi organics.. Yasiyidwa osasankhidwa, zinthu izi zimasefukira akasinja, kutseka mapaipi, amachepetsa mphamvu, ndipo zimatha kupangitsa kuti pakhale ma slip achitetezo kapena chindapusa cha chilengedwe. Silicone defoamer imalowa mkati kuti iteteze zonsezo pophwanya kapangidwe ka thovulo lisanakhale vuto..

Sayansi kumbuyo kwake ndi yabwino kwambiri. Mukawonjezera silicone defoamer ku foamy system, PDMS imafalikira mofulumira pamtunda wa kuwira chifukwa cha kuchepa kwake. Imachotsa stabilizing surfactant, kupatulira lamellae-makanema oonda omwe amanyamula thovu limodzi. Ndiye, silika imagwira ntchito ngati pini, kulimbikitsa kupsinjika ndi kupsinjika. Mabubu amalumikizana, kukula osakhazikika, ndi pop, kutulutsa mpweya wopanda vuto. Chomwe chimasiyanitsa ma silicones ndikukhazikika kwawo kwamafuta; amasunga kutentha mpaka 200 ° C kapena kuposa, kuwapanga kukhala abwino kwa njira zotentha zomwe zina zofooketsa zitha kusweka. Muzochitika zanga, kulimba uku kumatanthauza kuchepera kwa mapulogalamu komanso nthawi yocheperako - ndakhala ndikuwonetsa makasitomala 30-40% kuchepa kwa kukonza pambuyo pa kusintha.

Chimodzi mwazothandiza kwambiri ndi kusinthasintha. Ma silicone defoamers amabwera m'njira zosiyanasiyana: emulsions kwa kachitidwe ka madzi, mankhwala kwa omwe si amadzimadzi, kapena ufa wosakaniza wowuma. Emulsions, Mwachitsanzo, ndi zosungunuka m'madzi komanso zosavuta kuziphatikiza mu utoto kapena zomatira. M'mapulogalamu amtundu wa chakudya, timagwiritsa ntchito mitundu yovomerezedwa ndi FDA yopanda zitsulo zolemera, yabwino kuwongolera thovu pakuyenga shuga kapena kupanga moŵa. Zimakhalanso zopanda poizoni komanso zopanda pake, kotero samachita ndi zosakaniza zina kapena kusintha mtundu wazinthu. Pamtengo, pamene iwo ali okwera patsogolo kuposa mafuta amchere, Kuchita bwino kwawo kumalipira-mlingo wocheperako umatanthauza kusunga nthawi yayitali. Pulojekiti yomwe ndidatsogolera yopanga zotsukira zidaphatikizapo emulsion ya silikoni yomwe imadula thovu lawo 70%, kulimbikitsa linanena bungwe popanda zipangizo zina.

Koma tiyeni tikhale enieni; sali angwiro pazochitika zilizonse. Muzinthu zina zachilengedwe, monga madzi ena otayira, ma silicones amatha kukweza mbendera chifukwa sizowonongeka kwathunthu ndipo amatha kudziunjikira ngati atagwiritsidwa ntchito mopitilira muyeso. Ichi ndichifukwa chake dosing ndikofunikira - mochuluka kwambiri, ndipo mumayika pachiwopsezo zotsalira za silikoni zomwe zimakhudza kusefera kapena zamoyo zam'madzi kunsi kwa mtsinje. Amakhalanso osagwira ntchito m'malo amchere kwambiri popanda ma tweaks. Poyerekeza ndi organic defoamers ngati polyglycols, ma silicones sangakhale ngati “wobiriwira,” koma ma hybrids akutseka mpatawo. Ndapanga zosakaniza ndi mafuta a masamba kuti zikwaniritse miyezo yolimba ya EU, kusunga nkhonya ya silikoni kwinaku mukuwongolera eco-friendlyliness.

Kupambana kwenikweni kwa dziko kumandipangitsa kuti ndikhale wotanganidwa ndiukadaulo uwu. Tengani zamkati ndi mphero mapepala ndinafunsira: thovu lochokera ku chakumwa chakuda linali likukwiyitsa ma evaporator awo, kuchititsa kuyeretsa pafupipafupi. Tinayambitsa gulu la silikoni losagwira kutentha, ndipo idakhazikitsa njira, kuchepetsa kugwiritsa ntchito mphamvu ndi 15% ndi kukulitsa moyo wa zida. Kapena mu pharmaceuticals, kumene mizere yodzaza yosabala silingathe kulekerera thovu-zowonongeka za silicon zimatsimikizira kuchulukitsidwa kolondola popanda kuipitsidwa. Ngakhale mu mafuta ndi gasi, amaweta thovu m’matope oboola, kuteteza kuphulika. Nkhanizi zikuwonetsa momwe mapangidwe opangidwira amapangira kusiyana konse; zinthu zopanda pake zimagwira ntchito, koma ma tweaks achizolowezi kutengera pH, kutentha, ndipo mtundu wa thovu umapereka zotsatira zabwino kwambiri.

Kuyang'ana kutsogolo, ma silicone defoams akukula mwachangu. Zowonjezera za nano-silica zikuwapangitsa kukhala amphamvu kwambiri pamilingo yaying'ono, kuchepetsa kukhudzidwa kwa chilengedwe. Matembenuzidwe ogwirizana ndi bio pogwiritsa ntchito ma silikoni osinthidwa ali m'ntchito zamapulogalamu omvera ngati biotech. Ndi kusowa kwa madzi padziko lonse lapansi, gawo lawo pakubwezeretsanso madzi akuwonongeka moyenera lidzakula - lingalirani zopukutira zanzeru zomwe zimadzisintha zokha kudzera pa masensa. Kafukufuku wokhazikika pakufufuza, monga silicones zobwezerezedwanso, ikulonjezanso. M'malingaliro mwanga, monga mafakitale akukankhira kwa obiriwira obiriwira, ma silicones adzasintha, kukhala oyenera.

Pomaliza pake, silicone defoamer ndi zochuluka kuposa mankhwala; iwo ndi othetsa mavuto omwe amapangitsa kuti mafakitale aziyenda. Iwo akhala mkate wanga ndi batala, kusandutsa makasitomala okhumudwa kukhala okhulupirika. Ngati chithovu chikusokoneza ntchito yanu, ganizirani ma silicones-atha kukhala akuyang'anirani zomwe mukufuna. Chitanipo kanthu; zotsatira zake zikhoza kukudabwitsani.
