Mafunso Omwe Amafunsidwa Nthawi zambiri Zokhudza Kugwiritsa Ntchito Hydroxypropyll Methylcelulose

Kodi kugwiritsa ntchito ma hydroxypropyll methylcelulose?
Kugwiritsa ntchito kwambiri zida zomanga, zokutira, matekenti, mateni, mankhwala, chakudya, nsalu, zodzola, fodya komanso mafakitale ena. HPMC ikhoza kugawidwa mu: Grace Womanga, kalasi ya chakudya ndi kalasi ya mankhwala molingana ndi cholinga. Pakadali pano, ambiri mwazinthu zapakhomo ndi kalasi yomanga. Mu kalasi yomanga, kuchuluka kwa ufa wa putty ndi waukulu kwambiri, pafupifupi 90% amagwiritsidwa ntchito pavety ufa, ndipo ena onse amagwiritsidwa ntchito matope a simenti ndi gulu.

Kodi njira zosungunuka hydroxypypyl fiber?
1.

2. Njira yosakanikirana: Sakanizani ufa wa hpmc wokhala ndi zinthu zina zambiri zamafuta, ndikusungunula ndi madzi, ndipo isasungunuke ndi madzi pang'ono, ndipo idzasungunuka nthawi yomweyo ikakumana ndi madzi.

Kodi mungasankhe bwanji mafayilo a hydroxypypyl methylcellulose?
Sankhani maulendo osiyanasiyana malinga ndi mapulogalamu osiyanasiyana, kugwiritsa ntchito ufa wa putty: Mutha kusankha mafayilo a 100,000, chinthu chofunikira ndikusunga madzi bwino. Kugwiritsa kwa matope: Zofunikira kwambiri, kuwoneka bwino kwambiri, sankhani ma visn 150,000. Kugwiritsa ntchito guluu: Mukufuna zinthu zomwe mwapanga pompopompo, kuwoneka kwapamwamba, kusankha ma Isccence 200,000.

Momwe mungadziwire mtundu wa hydroxypropyl methylcellulose?
Kuyera kwake: Ngakhale kuyera sikutanthauza kuti hpmc ndikosavuta kugwiritsa ntchito, ndipo ngati wodekha amawonjezeredwa pakupanga, uzikhudza mtundu wake. Komabe, ambiri mwazinthu zabwino zimakhala ndi kuyera kwabwino.

Ubwino: Chisangalalo cha HPMC nthawi zambiri ma mesh ndi 100 mesh, ndi 120 mesh ndiwochepera. Ambiri hpmc opangidwa mu hebei ndi 80 mesh. Malipiro abwino, abwino.

Kutumiza: Ikani hydroxypropyl methylcellulose (hpmc) m'madzi kuti apange colloid colloid, ndikuyang'ana. Kuphatikizika kwa riyakitala riyakitala nthawi zambiri kumakhala kovuta, ndipo sikunganenere kuti mtundu wa rirtication uli bwino kuposa momwe umadziwira zabwino.

Mphamvu yokoka: yayikulu kwambiri mphamvu yokoka, yolemera. Mphamvu yokoka ndiyochulukirapo, makamaka chifukwa ma hydroxypropyl ali mkati mwake ali okwera, ndipo hydroxypropyl yomwe ili pamtunda, kusungidwa kwamadzi ndikwabwino.

Ubale pakati pa ma vinya ndi kutentha kwa hydroxypropyll methylcelulose
Zogwirizana za Vikecc ndizofanana ndi kutentha, ndiko kuti, monga kutentha kumachepa, kuyanja kwa mafayilo kumawonjezeka, ndipo yankho lake 2% limayesedwa pamtunda 20 Celsius. Pamapulogalamu othandiza, m'malo okhala ndi kutentha kwambiri pakati pa chilimwe komanso nthawi yozizira, kuyenera kudziwidwa kuti mafashoni otsika amagwiritsidwa ntchito nthawi yozizira, yomwe imathamangira yomanga.

Kodi udindo wa hpmc mu ufa ndi uti?
Mu ufa wa putty, hpmc amasewera ntchito zitatu: kukulitsa, kusungidwa kwamadzi ndikumanga.

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. HPMC sinatenge nawo mbali mwanjira iliyonse ya mankhwala ndipo imangodya mbali yothandiza. Kuonjezera madzi ku ufa wa putty ndikuyika pakhoma ndi mankhwala. Chifukwa cha kapangidwe ka zinthu zatsopano, tengani ufa wa putty pakhoma pakhoma, ndikupukuta mu ufa, ndikugwiritsanso ntchito. Sizigwira ntchito, chifukwa zinthu zatsopano (calcium carbonate) yapangidwa. ).

Zigawo zikuluzikulu za Ash calcium ufa ndi: osakaniza a ca (o) 2, caon rombon ma cacborate masheya, osatenga nawo gawo chilichonse.
