Kodi mawu oyenera a hydroxypypyl ndi chiyani methylcellulose?

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, ndipo zimachitika?

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, caon aphungu a CA2 Munjira iliyonse

Ubwenzi wapakati pa ufa ndi kutentha kwa HPMC, nchiyani chikuyenera kukhala chisamaliro cha ntchito yothandiza?

Makulidwe a HPMC ndi yolingana ndi kutentha, ndiye kuti, mafayilo amawonjezeka ngati kutentha kumachepa. Makutu a chinthu chomwe timakonda kutchula zotsatila za mayeso a 2% am'madzi pa kutentha kwa madigiri 20 Celsius.

Pogwiritsa ntchito, ziyenera kudziwika kuti m'malo omwe ali ndi kutentha kwambiri pakati pa chilimwe pakati pa chilimwe komanso nthawi yachisanu, tikulimbikitsidwa kugwiritsa ntchito mafayilo ocheperako nthawi yozizira, yomwe imathamangira yomanga. Kupanda kutero, kutentha kumakhala kotsika, mamasukidwe a cellulose achulukitsa, ndipo nthawi yomwe akumva kuti yatha.

Mafayilo apakatikati: 75000-100000 makamaka amagwiritsidwa ntchito
Chifukwa: Kusunga kwamadzi
