Makhalidwe a hydroxypropyl methylcellulose pakupanga

Zosungunuka m'madzi ndi zinthu zina zachilengedwe zimatha kusungunuka m'madzi ozizira, kuchuluka kwake kwakukulu kumangotsimikiziridwa ndi kukhuthala, kusungunuka kumasintha ndi kukhuthala, kukhuthala kutsika, kusungunuka kumakulirakulira.

Kukana Mchere: Hydroxypropyl methylcellulose yomangira ndi ether ya cellulose yosakhala ionic osati polyelectrolyte, kotero imakhala yokhazikika mu yankho lamadzi pamene mchere wachitsulo kapena ma electrolyte achilengedwe alipo, koma kuwonjezera ma electrolyte mopitirira muyeso kungayambitse kukhuthala kwa madzi. Guluu ndi mvula.

Ntchito ya pamwamba: chifukwa cha ntchito yogwira ntchito pamwamba pa yankho lamadzi, lingagwiritsidwe ntchito ngati choteteza cha colloidal, emulsifier ndi dispersant.

Ikatenthedwa kufika kutentha kwinakwake, madzi a hydroxypropyl methylcellulose omwe amapangidwa ndi gel yotenthetsera amakhala osawoneka bwino, ma gels, ndi madontho, koma ikazizira nthawi zonse, imabwerera ku momwe yankho limakhalira, ndipo kuzizira kumeneku kumachitika. Kutentha kwa guluu ndi mvula kumadalira makamaka mafuta awo, zinthu zopachikira, ma colloids oteteza, ma emulsifiers, ndi zina zotero.

Zinthu Zamalonda

Kuletsa chimfine: Ili ndi mphamvu yabwino yolimbana ndi chimfine komanso kulimba kwabwino pakusungidwa kwa nthawi yayitali.

Kukhazikika kwa PH: Kukhuthala kwa yankho lamadzi la hydroxypropyl methylcellulose lopangidwa sikukhudzidwa kwenikweni ndi asidi kapena alkali, ndipo pH ndi yokhazikika pakati pa 3.0 mpaka 11.0. Kusunga mawonekedwe Chifukwa yankho lamadzi la hydroxypropyl methylcellulose lopangidwa ndi madzi lomwe lili ndi mphamvu zapadera za viscoelastic poyerekeza ndi mayankho amadzi a ma polima ena, kuwonjezera kwake kungathandize kukonza mawonekedwe a zinthu zadothi zotulutsidwa.

Kusunga Madzi: hydroxypropyl methylcellulose yopangidwa ili ndi hydrophilicity komanso kukhuthala kwakukulu kwa yankho lake lamadzi, lomwe ndi chinthu chosungira madzi chogwira ntchito bwino kwambiri.

Zina mwazinthu: chokhuthala, chopangira filimu, chomangira, chopaka mafuta, choyimitsa, choteteza colloid, emulsifier, ndi zina zotero.
