Njira yosavuta yodziwira hydroxypropyl methylcellulose

Cellulose imagwiritsidwa ntchito kwambiri mu petrochemical, mankhwala, kupanga mapepala, zodzoladzola, zipangizo zomangira, ndi zina zotero. Ndi chowonjezera chogwiritsidwa ntchito mosiyanasiyana, ndipo ntchito zosiyanasiyana zimakhala ndi zofunikira zosiyanasiyana pa ntchito zopangidwa ndi cellulose.

Nkhaniyi ikufotokoza makamaka momwe HPMC (hydroxypropyl methylcellulose ether) imagwiritsidwira ntchito komanso njira yodziwira ubwino wake, yomwe imagwiritsidwa ntchito kwambiri mu ufa wamba wa putty.

HPMC imagwiritsa ntchito thonje loyengedwa bwino ngati chinthu chachikulu chopangira zinthu. Imagwira ntchito bwino, mtengo wake ndi wokwera komanso wokana kugwiritsa ntchito zinthu za alkali. Ndi yoyenera kugwiritsa ntchito matope wamba osalowa madzi ndi matope a polima opangidwa ndi simenti, calcium ya lime ndi zinthu zina zamphamvu za alkali. Kukhuthala kwake ndi 40,000-200000S.

Nazi njira zingapo zoyesera ubwino wa hydroxypropyl methylcellulose zomwe zafotokozedwa mwachidule ndi Xiaobian kwa inu. Bwerani mudzaphunzire ndi Xiaobian~

1. Kuyera:

Zachidziwikire, chinthu chofunikira kwambiri pakuzindikira mtundu wa hydroxypropyl methylcellulose sichingakhale kuyera kokha. Opanga ena amawonjezera zinthu zoyera popanga, pankhaniyi, mtundu wake sungaweruzidwe, koma kuyera kwa hydroxypropyl methylcellulose yapamwamba kwambiri ndi kwabwino kwambiri.

2. Kusalala:

Hydroxypropyl methylcellulose nthawi zambiri imakhala ndi ulusi wa 80 mesh, 100 mesh ndi 120 mesh. Ulusi wa tinthu tating'onoting'ono ndi wabwino kwambiri, ndipo kusungunuka ndi kusunga madzi nazonso ndi zabwino. Iyi ndi hydroxypropyl methylcellulose yapamwamba kwambiri.

3. Kutumiza kuwala:

Ikani hydroxypropyl methylcellulose m'madzi ndikuisungunula m'madzi kwa kanthawi kuti muwone kukhuthala ndi kuwonekera bwino. Gel ikapangidwa, yang'anani momwe kuwala kumayendera, momwe kuwala kumayendera bwino, komanso momwe zinthu zosasungunuka komanso kuyera kwake kumakulirakulira.

4. Mphamvu yokoka yeniyeni:

Mphamvu yokoka yeniyeni ikakhala yayikulu, imakhala yabwino, chifukwa mphamvu yokoka yeniyeni ikakhala yolemera, kuchuluka kwa hydroxypropyl methyl mkati mwake kumakhala kwakukulu, ndipo kusunga madzi kumakhala bwino.
