Hydroxypropyl methyl cellulose imatha kukulitsa kukana kwa matope a simenti

Kukana kukana ndi mndandanda wofunikira waluso kuti muyeze mtundu wa anti - obalalika.Hydroxypropyl methyl cellulosendi malo osungunuka osungunuka madzi, omwe amadziwikanso kuti ndi osungunuka madzi kapena osungunuka madzi. Zimachulukitsa kusasinthika kwa kusakaniza ndikuwonjezera mafayilo osakanikirana. Ndi mtundu wa hydrophilic polymer zinthu, zomwe zimatha kusungunuka m'madzi ndikupanga yankho kapena kusungunuka kwamadzi. Kuyesera kumawonetsa kuti kuchuluka kwa matenda a Naphthalene SpenPucise GrantPracise, kuphatikiza kwa SuperPlastiction kumachepetsa kukana kwa matope atsopano a simenti. Izi ndichifukwa choti Naphthalene Biby Madzi Ogwiratsa Madzi Oyenera Othandizira Wothandizira, Madzi akamachepetsa mankhwalawo Malo okhala timenti timene simenti opangidwa ndi kugawa, kukulunga mu kapangidwe ka madzi, kudzapangitsa kukhala kwa simenti. Nthawi yomweyo, zimapezeka kuti ndi kuchuluka kwa zomwe zili mu HPMC, kupezeka kwa matope a CERE ndikwabwino komanso bwino.

Makhalidwe A Craceri:

HPMC pansi pamadzi osamwa osakaniza adayikidwa mu mlatho waupangiri wa mlatho wa exprivey, ndipo mapangidwe opanga mphamvu anali C25. Pambuyo pa mayeso oyambira, Mlingo wa simenti ndi 400kg, ophatikizika osakanizidwa a silica 25kg / m3,HpmcMlingo woyenera ndi 0,6% ya Mlingo wa simenti, quio ya madzi ndi 0.42, Mlingo wa mchenga ndi 40%, katswiri wazowonjezera pa Arde 28D, mphamvu yayikulu ndi 42.6MPA, Mphamvu yapakati pa madzi adatsanulira konkire ndi kutalika kwa 60.4mka kwa masiku 28, ndipo chiwerengero champhamvu cha konkriti chimapangidwa ndi mpweya ndi 84.8%, kuwonetsa chofunikira.

1. Kuphatikiza kwa HPMC kuli kowonekera kowonekera pamatope osakaniza matope. Ndi kuwonjezeka kwa mlingo wa HPMC, nthawi ya matope imayamba nthawi yayitali. Pansi pa mlingo womwewo wa HPMC Mlingo, nthawi ya matope a pansi pamadzi ndi yayitali kuposa mpweya. Izi ndizopindulitsa pamapulogalamu a konkire pansi pamadzi.

2, osakanizidwa ndi hydroxypropyl methy cellulose ya matope atsopano a simenti ali ndi cousion, pafupifupi palibe magazi otaya magazi.

3, Mlingo wa HPMC ndi madzi opulumutsa matope adachepa kenako ndikutsika kenako ndikuwonjezeka kwambiri.

4. Kusasintha kwamadzi kumathandizira vuto lakukulitsa madzi ofunikira matope, koma ayenera kuyang'aniridwa, mwina nthawi zina nthawi zina amachepetsa kukana kwa matope atsopano a CERE.

5. Pali kusiyana pang'ono popanga ma cement sitemer a net ndi zonena zambiri, ndipo pamakhala kusiyana pang'ono pokha, ndipo pali kusiyana pakati pa ma cementine a simenti ndi mpweya wabwino. Chifaniziro champhamvu cham'madzi cham'madzi chimangosulidwa pang'ono. Cholinga chachikulu ndikuti kuwonjezera kwa HPMC kumachepetsa kwambiri kutayika kwa simenti m'madzi kuthirira madzi, komanso kumachepetsa kuchuluka kwa simenti. Pa ntchitoyi, mothandizidwa ndi madzi omwe sakubalalitsa madzi, kuchuluka kwa HPMC kumachepetsedwa monga momwe tingathere.

6, onjezaniHpmcPansi pa Madzi simabalalitsa konkire, onetsetsani kuchuluka kwa mphamvu, polojekiti yoyendetsa ndege imawonetsa kuti chiwerengero cha mphamvu zopanga ma simenti ndi 84.8%, zotsatirazi ndizofunikira kwambiri.
