Kuyerekezera Hec ndi Otsatsa Ena

Otsatsa amagwiritsidwa ntchito kwambiri pakupanga mafakitale, kuphatikizapo zokutira, zomangamanga, zodzola, chakudya ndi mankhwala. Hydroxyethyl cellulose (Hec) ndi wofunika kwambiri womwe wakopa chidwi ndi zomwe amapanga komanso kugwiritsa ntchito kwakukulu.

1. Kupanga ndi gwero
Hec ndi ethel etheluul yopangidwa ndi cellulose yokhudzana ndi Ethylene oxide. Ndiwo polymer wopanda main-sould ndi bata wabwino. Mosiyana ndi zimenezo, okumbika ali ndi magwero osiyanasiyana, kuphatikizapo izi:

Otsatsa achilengedwe a polysacharide: monga Xanthan chingamu ndi Guar chingamu, otuwa awa amachokera ku mbewu zachilengedwe kapena kuteteza chilengedwe komanso kuteteza kwambiri chilengedwe.

Okongoletsa Ackers: monga acrylic acid ma policrs (carbomer), omwe amaphatikizidwa potengera petrochemicals, khalani ndi magwiridwe antchito, koma osauka, koma osauka.

Ma protein Otsatanira Ma protin: Monga gelatin, zimachokera ku ziwalo za nyama ndipo ndizoyenera chakudya ndi mankhwala.
Hec ali ndi chilengedwe chonse chachilengedwe cha cellulose yachilengedwe komanso magwiridwe antchito abwino kwambiri osinthika, kupeza bwino pakati paubwenzi ndi mgwirizano ndi mgwirizano.

2. Magwiridwe okulitsa
Hec ali ndi izi m'machitidwe okulirapo:

Kusungunuka: Hec imatha kusungunuka m'madzi ozizira ndi madzi otentha kuti apange yankho lowonekera la viscous lokhala ndi kuchuluka kwa chilengedwe. Xanthan chingamu nthawi zambiri pamafunika mphamvu yolowera kuthandiza kufooka, ndipo yankho lingakhale ndi vuto linalake.
Kusintha Kwaku Vilony: Posintha ma celecular kulemera ndi kuchuluka kwa zowonjezera za Hec, zinthu zomwe zili ndi mahekidwe osiyanasiyana akuwoneka kuti zitha kupezeka kuti zikwaniritse zofunika zosiyanasiyana. Mosiyana ndi izi, kusinthasintha kwa ma vistoni kwa Guar Gum ndi wocheperako. Ngakhale acrylic acid policmer ali ndi mphamvu yotsatsa, imakonda kwambiri pH yamtengo.
Shear Shereng Act: Hec ili ndi mitanda yofatsa ndipo ndiyoyenera nthawi yomwe ma visction amafunika kusungidwa. Xanthan chingamu ali ndi pseudoplastity yofunika kwambiri ndipo ndi yoyenera kugwiritsa ntchito zokutira ndi ma emulsions chakudya.

3.. Kukhazikika kwa Mankhwala
Hec ali ndi bata yabwino mu p Poyerekeza:

Xanthan chingamu ali ndi mchere woletsa mchere kuposa hec, koma amawonongeka mosavuta pansi pa acid acid ndi alkali.
Makilopa a acrylic amakhudzidwa ndi asidi ndi alkali, ndipo amakonda kulephera mchere wambiri.
Kukhazikika kwamankhwala kwachilengedwe polysaccharide pansi pa kutentha kwambiri ndi oxida nthawi zambiri sizabwino monga Hec.

4. Kusiyana m'malo ogwiritsira ntchito
Zokutira ndi zomangira: Hec nthawi zambiri amagwiritsidwa ntchito pothandizidwa ndi madzi, putty ufa ndi matope, kupereka kukula kwamphamvu komanso kuthira kwamadzi. Xanthan chingamu chimagwiritsidwa ntchito kwambiri mu zida zamadzi, makamaka chifukwa cha kugwedeza kwake.
Zodzikongoletsera ndi mankhwala amtsiku ndi tsiku: Hec imatha kupereka khungu losalala komanso kukula bwino, ndipo limagwiritsidwa ntchito kwambiri m'maso ndi mafuta odzola. Makili a acrylic amakhala ndi mwayi wopanga gel a gel osakaniza ndi mphamvu zawo zazikulu komanso kuthekera kwakukulu.
Chakudya ndi mankhwala: Xanthan chingamu ndi guar chingamu chimagwiritsidwa ntchito kwambiri mu chakudya ndi mankhwala chifukwa cha chilengedwe chawo komanso zopanda pake. Ngakhale Hec imatha kugwiritsidwanso ntchito pokonzekera kusungidwa ndi mankhwala omasulira, imakhala ndi ntchito zochepa za chakudya.

5. Zachilengedwe ndi mtengo
Hec ndi wochezeka komanso wopanda chilengedwe chifukwa umapangidwa chifukwa cha cellulose. Kupanga ma poyipi a ma acrylic kumakhudza kwambiri chilengedwe ndipo ndizovuta kuthetsa pambuyo potaya. Ngakhale Jaanthan chingamu ndi guar chilengedwe ndiochezeka zachilengedwe, mitengo yake nthawi zambiri imakhala yokwera kuposa Hec, makamaka yosinthidwa pazogwiritsa ntchito zapadera.

Monga chotsirizira ndi ntchito yoyenera, hec imakhala ndi mwayi wapadera m'minda yambiri. Poyerekeza ndi chingamu cha xanthan ndi Guar chingamu, hec ndi mpikisano mu kukhazikika kwamankhwala ndi mphamvu; Poyerekeza ndi acrylic polima, Hec ndi wochezeka kwambiri ndipo amasunganizidwa kwambiri kutengera kutengera. Mwa kusankha kwenikweni, zinthu monga kukula kwamphamvu, kukhazikika kwa mankhwala ndi mtengo wake ziyenera kufotokozedwa molingana ndi zofunikira mwatsatanetsatane kuti mukwaniritse zabwino ndi mtengo wake.
