HPMC for Honeycomb Ceramics

HPMC, kapena hydroxypropyl methylcellulose, ndi mtundu wa polima wopangidwa ndi cellulose womwe wagwiritsidwa ntchito mosiyanasiyana, kuphatikiza ngati chomangira muzoumba za zisa.Zoumba za zisa ndi mtundu wa zinthu za ceramic zomwe zimapangidwa ndi netiweki ya maselo olumikizana, omwe amatha kugwiritsidwa ntchito m'njira zosiyanasiyana, monga zosefera, zopangira, ndi zosinthira kutentha.HPMC ndi chomangira choyenera cha zisa zadothi chifukwa champhamvu zake zomangirira, zotsika mtengo, komanso kugwiritsa ntchito mosavuta.

HPMC ndi polima osungunuka m'madzi omwe amapangidwa ndi ma cellulose omwe asinthidwa ndi magulu a hydroxypropyl.Kusintha uku kumapangitsa kuti polima ikhale yosungunuka kwambiri m'madzi ndipo imapangitsa kuti ikhale yolimba kwambiri kuposa ma polima ena opangidwa ndi cellulose.HPMC ndiyokhazikikanso kwambiri ndipo imatha kupirira kutentha kwambiri, ndikupangitsa kuti ikhale yomangira bwino zisa zadothi.

HPMC ikagwiritsidwa ntchito ngati chomangira mu zisa za zisa, HPMC imasakanizidwa ndi zinthu zina, monga dongo, silika, ndi alumina, kupanga slurry.Izi slurry ndiye anatsanulira mu nkhungu ndi kuloledwa kuti ziume.Pamene slurry auma, HPMC imamanga zosakaniza zina pamodzi, kupanga zisa za ceramic zolimba ndi zolimba.

HPMC imagwiritsidwanso ntchito pazinthu zina, monga zomatira, zokutira, ndi zinthu zamapepala.M'mapulogalamu awa, HPMC imapereka mgwirizano wamphamvu pakati pa malo awiri, ndikupangitsa kuti ikhale chisankho chabwino pazinthu zosiyanasiyana.

HPMC ndi chomangira chamitundumitundu komanso chotsika mtengo chomangira zisa zadothi.Ndi yosavuta kugwiritsa ntchito, imakhala ndi mphamvu zomangirira kwambiri, ndipo imakhala yokhazikika pakatentha kwambiri.HPMC nawonso si poizoni ndi wochezeka chilengedwe, kupangitsa kukhala yabwino kusankha ntchito zosiyanasiyana.
