Kuchuluka kwa HPMC yomwe imagwiritsidwa ntchito mu mapulogalamu othandiza kumasiyananso malinga ndi nyengo, kutentha, mtundu wa phulusa lapakatikati, njira ya putty ufa ndi "zofunikira ndi makasitomala". Nthawi zambiri, pali pakati pa 4 kg ndi 5 kg. Mwachitsanzo: ambiri a ufa ku Beijing ndi 5 kg; Ambiri mwa ufa wa putty mu guizhou ndi 5 makilogalamu m'chilimwe ndi 4.5 makilogalamu nthawi yozizira; Kuchuluka kwa putty ku Yunnan kuli kochepa, nthawi zambiri makilogalamu atatu mpaka 4 kg, etc.
Kodi mawonekedwe oyenera a hydroxypropyll methylcellulose (hpmc) chifukwa cha kupanga ufa?
Mafuta a putty nthawi zambiri amakhala okwanira 100,000, ndipo zofuna za matope ndizokwera, ndipo 150,000 yun ndiyofunikira kuti igwiritse ntchito mosavuta. Kuphatikiza apo, ntchito yofunika kwambiri ya HPMC ndi kusungidwa kwamadzi, kenako ndikukula. Mu ufa wa putty, bola ngati kusungidwa kwamadzi ndikwabwino ndipo mafayilo ali otsika (70,000-80,000), nkothekanso. Inde, mafakiti apamwamba, abwinobwino achibale. Maonekedwe oposa 100,000, chidwi cha ma visc chimakhudza kusungidwa kwamadzi. Osatinso.
Kodi ntchito yayikulu ndi iti yomwe imagwiritsidwa ntchito kwa HPMC mu ufa?
Mu ufa wa putty, HPMC imasewera maudindo atatu a kukula, kusungidwa kwamadzi ndikumanga.
Kukula: cellose imatha kukwiya kuyimitsa ndikusunga yunifolomu ndikutsika, ndikupewa kusamba.
Kusungidwa kwamadzi: Pangani utoto wa putty pang'onopang'ono, ndikuthandizira calcium kuti muchitepo kanthu pansi pamadzi.
Ntchito Yomanga: Cellulose ili ndi mafuta owuma, omwe amatha kupangitsa kuti ufa ukhale ndi zomangamanga.
HPMC sitenga nawo mbali pamavuto aliwonse, koma imangochita ntchito yothandiza. Kuonjezera madzi ku ufa wa putty ndikuyika pakhoma ndikuchitika kwa mankhwala, chifukwa zinthu zatsopano zimapangidwa. Mukachotsa ufa wa pakhoma kuchokera kukhoma, ndikupukuta mu ufa, ndikuigwiritsanso ntchito, sizigwira ntchito chifukwa zinthu zatsopano (calcium carbonate) yopangidwa. Nawonso. Zigawo zikuluzikulu za Ash calcium ufa ndi: osakaniza a ca (o) 2, cao = ca (o) 2 c2o Mu CO2 m'madzi ndi mpweya pansi pa mkhalidwewu, calcium carbonate, pomwe hpmc imangokhala ndi madzi, kuthandiza momwe amathandizira aphukira, osatenga nawo gawo limodzi.
