Kukula kwa hydroxypropyll methylcelulose

Hydroxypropyll methylcellulose matope onyowa matope ndi mawonekedwe abwino kwambiri, omwe amatha kuwonjezera matope pakati pa matope, ndikuwongolera matope a matope. Matope. Kukula kwa ether ether ether kumawonjezeranso luso lobalalitsa kwazinthu zatsopano za simenti, kupewa matope ndi kumeterera konkriti komanso konkriti wodziletsa.

Hydroxypropyll methyllulose imawonjezera mawonekedwe a zinthu zochokera ku mafayilo a cellulose eleber ether. Makutu a ethel ethel ethel nthawi zambiri amawunikiridwa ndi index index. Makutu a cellulose ether nthawi zambiri amatanthauza ndende inayake (monga 2%) ya ethel ethel etheluse njira yoyeserera ndi chiwopsezo cha liwiro (kapena kuzungulira kwa 20 rpm).

Ma Ukuwoneka ndi gawo lofunikira kuti muyesere magwiridwe antchito a cellulose. Kukula kwa ma virucypropyl methylcellulose yankho, mafayilo azomwe zachokera m'zinthu za simenti, zomwe zimapangitsa kuti zikhale bwino kwambiri, zotsatsa ndi luso lotsutsa komanso lotsutsa. Zamphamvu, koma ngati ma visy ndiakulu kwambiri, zimakhudza madzi ndi kusinthika kwa zinthu za simenti (monga kugwirira ntchito kumatayala popanga matonge matonge). Chifukwa chake, mawidwe a cellulose ether omwe amagwiritsidwa ntchito matope osakanikirana nthawi zambiri amakhala 15,000 ~ 60,000 MPA. S-1, matope okhaokha komanso konkriti wodziletsa zomwe zimafuna kuti madzi akumwamba amafunikira mafayilo otsika a cellulose ether ether.

Kuphatikiza apo, zotsatira za kukula kwa hydroxpyl methylcelulose zimawonjezera kuchuluka kwa zida za simenti, potero kuwonjezera zokolola za matope.

Makutu a hydroxypropyll methylcellulose njira imatengera zinthu zotsatirazi:

Cellulose ether cell (kapena digiri ya polymerization) ndi ndende, yankho, kutentha, mtengo wamahanga, ndi njira zoyesera.

1. Mpaka kuchuluka kwa polymerization wa cellulose ether, chokulirapo kunenepa, komanso kukwera kwa mafayilo ake;

2. Mlingo wapamwamba (kapena ndende) ya ethel ether, mawonekedwe ake am'magazi ake am'madzi, koma chisamaliro chake chiyenera kulipidwa kuti musankhe gawo loyenera mukamagwiritsa ntchito matope a matope ndi konkrizi;

3. Monga zakumwa zambiri, mafayilo a eleluse elefase amatha kuchepa ndi kuchuluka kwa kutentha, ndi kuchuluka kwa ma cellulose ether ether, ndiye kutentha kwakukulu;

4. Ma Exuluse ether souni nthawi zambiri amakhala pseudoplastics ndi shear kupatulira katundu. Mtengo wokwera pamasewera pa mayeso, kutsitsa ma visc.

Chifukwa chake, chilengedwe cha matope chidzachepetsedwa chifukwa cha mphamvu yakunja, zomwe zimapindulitsa pakumanga kwa matope, kotero kuti matope atha kukhala ndi ntchito yabwino komanso yolumikizira nthawi yomweyo. Komabe, pamene kuchuluka kwa eleulse ensol ndi yotsika kwambiri ndipo mamasukidwe ake ndi ochepa kwambiri, imawonetsa mawonekedwe a madzi a Newtonia. Pamene kupsanjika kumawonjezeka, yankho lakelo lidzawonetsa mawonekedwe a pseudoplactic madzimadzi, ndi kuchuluka kwa ziwonetserozo, zowonekeratu.
