Kodi methylcellulose ndi antifoaming agent?

Methylcellulose ndi chochokera ku cellulose chomwe chimagwiritsidwa ntchito kwambiri muzamankhwala, chakudya ndi mafakitale. Ndi polima yosungunuka m'madzi makamaka yopangidwa ndi cellulose yachilengedwe yopangidwa ndi kusinthidwa kwamankhwala, ndipo imakhala ndi zinthu zambiri zapadera, monga kukhuthala, gelling, kuyimitsidwa, kupanga mafilimu ndi kusunga madzi.

Makhalidwe ndi ntchito za methylcellulose

Thickener ndi gelling agent: M'makampani azakudya, methylcellulose nthawi zambiri amagwiritsidwa ntchito ngati thickener ndi gelling agent kuti athandizire kukonza kapangidwe ndi kukoma kwa mankhwalawa. Mwachitsanzo, mu zinthu monga ayisikilimu, kupanikizana ndi kuvala saladi, methylcellulose imatha kupereka kukhuthala kwabwino komanso kukhazikika kwa mankhwalawa.

Onyamula mankhwala ndi othandizira: M'makampani opanga mankhwala, methylcellulose nthawi zambiri amagwiritsidwa ntchito ngati chothandizira mankhwala, monga binder ndi filler ya mapiritsi. Ikhoza kugwiritsidwanso ntchito ngati mankhwala osasunthika kuti athe kuwongolera kuchuluka kwa mankhwalawa ndikuwonetsetsa kukhazikika komanso kukhazikika kwa zotsatira za mankhwala.

Kugwiritsa ntchito zipangizo zomangira: Pazinthu zomangira, methylcellulose imagwiritsidwa ntchito ngati chowonjezera komanso chosungira madzi mu simenti, gypsum ndi zokutira kuti ntchito yomanga ikhale yolimba komanso yolimba.

Kusiyana pakati pa methylcellulose ndi antifoaming agents

Antifoaming agents ndi gulu la mankhwala omwe amagwiritsidwa ntchito kupondereza kapena kuchotsa thovu muzamadzimadzi, ndipo amapezeka kawirikawiri pokonza chakudya, mankhwala, zodzoladzola, kupanga mapepala, mankhwala, ndi mankhwala amadzi. Antifoaming wothandizira nthawi zambiri amagwira ntchito pochepetsa kuthamanga kwamadzimadzi kuti asapangike chithovu, kapena kulimbikitsa kugwa kofulumira kwa thovu. Ma antifoaming antifoaming amaphatikizanso mafuta a silicone, ma polyether, mafuta acid esters, ndi tinthu tolimba, monga silicon dioxide.

Komabe, methylcellulose si antifoaming wothandizira mwachilengedwe. Ngakhale methylcellulose akhoza kupanga njira viscous pamene kusungunuka m'madzi, ndi mamasukidwe akayendedwe a yankho zingakhudze mapangidwe thovu nthawi zina, alibe pamwamba yogwira katundu wa mmene antifoaming wothandizira. Mwa kuyankhula kwina, ntchito yaikulu ya methylcellulose ndi yakuti imakhala ngati thickener, gelling agent, suspending agent, etc., osati kugwiritsidwa ntchito makamaka kupondereza kapena kuthetsa thovu.

Chisokonezo chotheka ndi milandu yapadera

Ngakhale methylcellulose si antifoaming agent, m'mapangidwe ena enieni kapena zinthu zina, imatha kukhudza mwachindunji khalidwe la thovu chifukwa cha kukhuthala kwake komanso mawonekedwe ake. Mwachitsanzo, muzakudya zina kapena mankhwala osokoneza bongo, kukhuthala kwapamwamba kwa methylcellulose kumatha kuchepetsa mapangidwe a thovu kapena kupangitsa thovu lomwe lapanga kuti liwonongeke mwachangu. Komabe, izi sizimalola kuti zikhale ngati antifoaming agent chifukwa njira yake yaikulu yochitira zinthu ndi yosiyana kwambiri ndi chikhalidwe cha mankhwala ndi machitidwe a antifoaming agents.

Methylcellulose ndi chochokera ku cellulose chomwe chimagwiritsidwa ntchito kwambiri ndi ntchito zingapo, koma sichimatengedwa ngati antifoaming agent. Ngakhale zitha kukhala ndi zotsatira pakuchita thovu nthawi zina, izi sizikutanthauza kugwiritsa ntchito kwake kwakukulu kapena njira yake yochitirapo kanthu. Antifoaming agents nthawi zambiri amakhala ndi zochitika zenizeni zapamtunda komanso mphamvu zowongolera thovu, pomwe methylcellulose imagwiritsidwa ntchito kwambiri pakukulitsa, kutsitsa, kuyimitsa komanso kusunga madzi. Choncho, pogwiritsira ntchito methylcellulose, ngati antifoaming effect ikufunika, wothandizira wapadera wa antifoaming ayenera kusankhidwa kuti agwiritsidwe ntchito pamodzi.
