Kodi ndi zinthu ziti zomwe zingakhudze mafayilo a hydroxypropyl methylcelulose?

Pogwiritsa ntchito matope onyowa,hydroxypypyl methylcelluloseAli ndi katundu wabwino kwambiri, amatha kuwonjezera luso la matope ndi maziko osanjikiza, ndipo amathanso kusintha matope a matope, khoma lakunja la khoma lotupa ndi njerwa.

Chifukwa cha kukula kwa ethel ether ether, zitha kuwonjezera luso lobalalitsa ndi zida zosakanizika, ndipo amathanso kuletsa mavuto oletsa, tsankho komanso kutuluka m'matope ndi kutuluka. Itha kugwiritsidwa ntchito konkriti wa fibeti, konkriti pomtunda komanso konkriti wodziletsa.

Hydroxypypyl methylcelulose imatha kuwonjezera magwiridwe antchito a simenti. Izi zimapangitsa kuti mamasukidwe a cellulose athe. Nthawi zambiri, mndandanda wa mafayilo amagwiritsidwa ntchito kuweruza mafayilo a etheluse, pomwe kumakusintha kwa ethel ether enso, nthawi zambiri, kutentha kotsimikizika, madigiri 20 ndipo Mlingo wozungulira, pogwiritsa ntchito chida chofufumitsa, monga wotchire wozungulira. Mtengo wa Visccence.

Ma ufa ndi amodzi mwa magawo ofunikira kuti aweruze magwiridwe antchito a cellulose. Makutu apamwamba a hydroxypropyl methylcellulose yankho, mafayilo azomwe zidapangidwa ndi zinthu za simenti, komanso zabwinoko zomatira ku gawo lapansi. Nthawi yomweyo, ili ndi luso lothana ndi kufooka ndi lamphamvu, koma ngati maonedwe ake ndi okwera kwambiri, zimakhudza ntchito yoyenda ndi kubisala zinthu kwa simenti.

Kodi ndi zinthu ziti zomwe zingakhudze mafayilo a hydroxypropyl methylcelulose? Makamaka zimatengera zifukwa zotsatirazi.

1. Mpaka kuchuluka kwa polymerization wa cellulose ether wa hydroxypyllulosell, cholemera kwambiri moleclar, zomwe zimapangitsa kuti magazi ake azisintha.

2. Ngati kuchuluka kapena kukhazikika kwa cellulose ether ether kuli pamwamba, mafayilo ake am'madzi adzakhala okwera. Komabe, chisamaliro chikuyenera kutengedwa kuti chisankhe mu ethel ether ether ether poigwiritsa ntchito, makamaka kupewa kuchuluka kwa cellulose. Zidzakhudza matope a matope ndi konkriti.

3. Monga zakumwa zambiri, mafayilo a eleluse elefase amatha kuchepa ndi kuchuluka kwa kutentha, komanso kuchuluka kwa cellulose ether ether, kutsitsa kutentha. Zovuta zazikulu.

4. Njira ya cellulose nthawi zambiri imakhala preeudoplastic, yomwe ili ndi mikhalidwe ya Shear Shear. Mlingo waukulu wa chimbudzi pakuyesa, ang'onoang'ono akuwoneka.

Chiyanjano cha matope chidzachepetsedwa chifukwa cha mphamvu yakunja, yomwe imapindulitsanso kupangira matope a matope, zomwe zimapangitsa matope abwino komanso kugwirira ntchito kwa matope nthawi yomweyo. Komabe, ngaticellulose etherNjira yothetsera mavuto ambiri ikakhala yotsika ndipo maonedwewo ndi ochepa, iwonetsa mawonekedwe a Newtonian madzi. Kuchuluka pang'onopang'ono, yankho lakelo lidzawonetsa mawonekedwe a pseudoplactic madzi, ndipo ngati chidwi chili chachikulu, pseudophity udzakhala wowonekera kwambiri.
