Methyl hydroxyethyl celluloseImakonzedwa poika zinthu zolowa m'malo mwa ethylene oxide (MS0.3 ~ 0.4) mu methyl cellulose, ndipo kutentha kwake kwa gel kumakhala kokwera kuposa kwa methyl cellulose ndi methyl hydroxypropyl cellulose. , magwiridwe ake onse ndi abwino kuposa methyl cellulose ndi methyl hydroxypropyl cellulose.
Methyl hydroxyethyl cellulose imagwiritsidwa ntchito makamaka ngati chokhuthala, chokhazikika komanso choteteza colloid mu matope omangidwa ndi zokutira zochokera m'madzi.

Kapangidwe ka thupi ndi mankhwala
1. Kusungunuka: Kusungunuka m'madzi ndi zinthu zina zachilengedwe, kuchuluka kwakukulu kumadalira kokha kukhuthala, kusungunuka kumasintha ndi kukhuthala, kukhuthala kutsika, kusungunuka kumakulirakulira.
2. Kukana Mchere: Chogulitsachi ndi ether ya cellulose yosakhala ionic, yomwe imakhala yokhazikika mu yankho lamadzi, koma kuwonjezera kwambiri kwa electrolyte kungayambitse kusungunuka kwa madzi ndi mvula.
3. Ntchito ya pamwamba: Popeza madzi amadzi ali ndi ntchito ya pamwamba, angagwiritsidwe ntchito ngati choteteza cha colloid, emulsifier ndi dispersant.
4. Gel wotentha: Pamene yankho lamadzi la chinthucho litenthedwa kufika kutentha kwinakwake, limakhala losawoneka bwino, losaoneka bwino, ndipo limapanga mpweya wozizira, koma likaziziritsidwa nthawi zonse, limabwerera ku momwe yankholo linalili poyamba.
5. Kagayidwe kachakudya: Kagayidwe kachakudya ndi kosagwira ntchito ndipo kali ndi fungo lochepa komanso fungo lochepa. Chifukwa chakuti sizimagayidwa ndipo zili ndi fungo lochepa komanso fungo lochepa, zimagwiritsidwa ntchito kwambiri mu chakudya ndi mankhwala.
6. Kukana chimfine: Ili ndi mphamvu yabwino yolimbana ndi chimfine komanso kulimba kwabwino pakusungidwa kwa nthawi yayitali.
7. Kukhazikika kwa PH: Kukhuthala kwa madzi a yankho la chinthucho sikukhudzidwa kwambiri ndi asidi kapena alkali, ndipo PH ndi yokhazikika pakati pa 3.0-11.0.
8. Kuchuluka kwa phulusa: Popeza mankhwalawa si a ionic, amayengedwa bwino powatsuka ndi madzi otentha panthawi yokonzekera, kotero kuchuluka kwa phulusa lake kumakhala kochepa kwambiri.
9. Kusunga mawonekedwe: Popeza yankho lamadzi lokhala ndi mphamvu zambiri la chinthucho lili ndi mphamvu zapadera za viscoelastic poyerekeza ndi mayankho amadzi a ma polima ena, kuwonjezera kwake kumatha kukonza mawonekedwe a zinthu zadothi zotulutsidwa.
10. Kusunga madzi: Kusinthasintha kwa madzi mu chinthuchi komanso kukhuthala kwa madzi ake kumapangitsa kuti chikhale chothandiza kwambiri posunga madzi.

Kulongedza ndi kutumiza:
Kulemera konsekonse kwa 25 kg, thumba la pepala lopangidwa ndi pulasitiki, likhoza kusinthidwa malinga ndi zosowa za makasitomala.
Mankhwalawa amayamwa chinyezi mosavuta ndipo ayenera kusungidwa pamalo ozizira komanso ouma.
