Methyl hydroxyethyl cellulose imakonzedwa poyambitsa ethylene oxide substituents (MS0.3 ~ 0.4) mu methyl cellulose, ndipo kutentha kwake kwa gel kumakhala kopambana kuposa methyl cellulose ndi methyl hydroxypropyl cellulose. , ntchito yake yonse ndiyabwino kuposa methyl cellulose ndi methyl hydroxypropyl cellulose.
Methyl hydroxyethyl cellulose amagwiritsidwa ntchito makamaka ngati thickener, stabilizer ndi colloid zoteteza mumatope zomangamanga ndi zokutira madzi.

ufa woyera kapena wachikasu pang'ono
Thupi ndi mankhwala katundu
1. Solubility: sungunuka m'madzi ndi zosungunulira organic, ndende yapamwamba imangotengera mamasukidwe akayendedwe, solubility amasintha ndi mamasukidwe akayendedwe, m'munsi mamasukidwe akayendedwe, kwambiri solubility.
2. Kukaniza mchere: Mankhwalawa ndi osakhala aionic cellulose ether, omwe amakhala okhazikika mumadzimadzi, koma kuwonjezera kwambiri kwa electrolyte kungayambitse gelation ndi mpweya.
3. Ntchito yapamtunda: Chifukwa njira yamadzimadzi imakhala ndi ntchito yapamtunda, imatha kugwiritsidwa ntchito ngati chitetezo cha colloid, emulsifier ndi dispersant.
4. Gel yotentha: Pamene madzi amadzimadzi a mankhwala atenthedwa ku kutentha kwina, amasanduka opaque, gels, ndipo amapanga mpweya, koma atakhazikika mosalekeza, amabwerera ku chikhalidwe choyambirira.
5. Metabolism: Metabolism ndi inert ndipo imakhala ndi fungo lochepa komanso fungo labwino. Chifukwa chakuti samapangidwa ndi metabolic ndipo amakhala ndi fungo lochepa komanso fungo labwino, amagwiritsidwa ntchito kwambiri muzakudya ndi zamankhwala.
6. Kulimbana ndi mildew: Ili ndi mphamvu yabwino yolimbana ndi mildew komanso kukhazikika kwa viscosity panthawi yosungidwa kwa nthawi yaitali.
7. Kukhazikika kwa PH: Kuthamanga kwa njira yamadzimadzi ya mankhwala sikukhudzidwa kwambiri ndi asidi kapena alkali, ndipo mtengo wa PH umakhala wosasunthika pakati pa 3.0-11.0.
8. Phulusa lochepa la phulusa: Popeza kuti mankhwalawa ndi osakhala a ionic, amayeretsedwa bwino ndikutsuka ndi madzi otentha panthawi yokonzekera, kotero kuti phulusa lake ndi lochepa kwambiri.
9. Kusungirako mawonekedwe: Popeza kuti njira yowonongeka kwambiri yamadzimadzi ya mankhwalawa ili ndi katundu wapadera wa viscoelastic poyerekeza ndi njira zamadzimadzi za ma polima ena, kuwonjezera kwake kumatha kusintha mawonekedwe a zinthu za ceramic extruded.
10. Kusungirako madzi: Kuchuluka kwa hydrophilicity ya mankhwalawa ndi kukhuthala kwake kwamadzimadzi kumapangitsa kuti ikhale yothandiza posungira madzi.

Utoto wapakhoma wamkati ndi kunja (penti yamwala yeniyeni)
Kupakira ndi kutumiza:
25 kg ukonde kulemera, pepala-pulasitiki gulu thumba, akhoza makonda malinga ndi zofuna za makasitomala.
Mankhwalawa amatenga chinyezi mosavuta ndipo ayenera kusungidwa pamalo ozizira, owuma.
