Gawo la hydroxypropyl methylcellulose

Gawo la hydroxypropyl methylcellulose

Kuchokera pakukula, kusungidwa kwamadzi ndikumanga ntchito zitatu.

Kukula: Cellulose imatha kukuwuma kuti iyimitse, kusungitsa yunifolomu ndi kosasintha, ndikupewa kusanja. Kusungidwa kwamadzi: Pangani utoto wa putty pang'onopang'ono, ndikuthandizira zomwe zimachitika phulusa pansi pamadzi. Ntchito Yomanga: Cellulose ili ndi mafuta owuma, omwe amatha kupangitsa kuti ufa ufa akhale wogwira ntchito bwino. Hydroxypypyl Nomeylcellulose satenga nawo mbali mwanjira iliyonse ya mankhwala ndipo imangodya mbali yothandiza. Ufa putty umawonjezeredwa ndi madzi kuti atchere khomalo, lomwe ndi mankhwala a mankhwala, chifukwa pali mapangidwe a carbonate yatsopano carbonate. Zigawo zikuluzikulu za Ash calcium ufa ndi: kusakaniza kwa calcium hydroxide ca (o) 2, calcium oxide ca cabobote crisbonate ya cacon. Ash calcium imapanga calcium carbonate pansi pa katatu m'madzi ndi mpweya, pomwe hydroxypropyl centyl celly celyose imangokhala ndi calcium yomwe imangochita nawo.

Choyamba tipenda zifukwa zokhala ndi ufa kuchokera ku dothi lopanda pake: phulusa la ma hydroxypyllulose, ma calcium illoun, madzi phulusa ufa wa calcium

1. Popanga zenizeni, kuti mufulumizire kuwonongeka, kutentha kwanyengo kumawonjezeka mpaka 1000-1100 ° C. Chifukwa cha kukula kwakukulu kwa zida zamiyala kapena kugawa kutentha pang'ono mu kilge pa kuwerengedwa, laimu nthawi zambiri kumakhala ndi laimu yokhazikika komanso laimu yolunjika. Discium carbonate ya pantiio yomwe ili pansi paime siyikulipitsidwa kwathunthu, ndipo imatha kupereka mphamvu yolumikizirana yogwiritsira ntchito, zomwe sizingapereke mphamvu yolumikizira kuthya, zomwe zimapangitsa kuti pakhale kuwuka kosakwanira.

2. Opambana a calcium hydroxide mu phulusa la calcium, ndibwino kuuma kwapamwamba. M'malo mwake, kutsitsa zomwe zili ku calcium hydroxide mu phulusa la calcium, kuvuta kwambiri pakuchotsa ufa, kuchotsera ufa.

3. Ntchito yayikulu ya ufa ndi kusunga madzi, perekani madzi okwanira kuwuma phulusa, ndikuwonetsetsa kuti akulimbana bwino. Ngati pali vuto ndi mtundu wa hydroxypylropyl kapena zothandiza ndi zochepa, chinyezi chokwanira sichingapangitse kusakwanira ndi kusakwanira kuti ukhale wopanda ufa.

Itha kupezeka kuchokera pamwambapa kuti mtundu wa hydroxypypyl methylcelulose ndiosauka kwambiri ndipo sangakwaniritse zina, ndipo ufa wa putty umagwa. Chifukwa chachikulu ndi imvi chofufuzira kwambiri.
