Kodi zotsatira za hydroxypropyl ndi chiyani methylcellulose pa matope a simenti?

Hydroxypypyl methylcellulose imatha kukonza matope obalalitsidwa.

Hydroxypypyl methylcellulose ndi mafuta osungunuka. Nthawi zambiri zimachulukitsa kusakaniza kwa osakaniza pochulukitsa mafayilo osakanikirana. Itha kusungunuka m'madzi kuti apange yankho la ma viscous. Ndi ma polymeric polima. Kudzera mwa kuyesa, titha kupeza ndalama zochuluka kwambiri za surthalogizer mu mavalidwe a simenti kumawonjezeka, kuphatikizika kwa superplasticizer kumachepetsa kukana kwa matope osakanikirana. Chifukwa chiyani zina zoterezi zimachitika? Izi ndichifukwa chakuti madzi otsika kwambiri amadziwa kwambiri amathandiza kwambiri. Kutsika kwamadzi akamagwiritsidwa ntchito m'matope a simenti, idzayang'aniridwa pamwamba pa simenti tinthu tambiri kuti apange mawonekedwe a simenti tinthu omwewo. Kunyadaku kwa magetsi kumeneku kumapangitsa simenti ya simenti ipanga simenti ya kukondwerera kwa simenti ikhale yovuta, ndipo madzi okutidwa ndi kapangidwe kake kamatulutsidwa, zomwe zingapangitse gawo la kutayika kwa simenti. Nthawi yomweyo, idapezeka kuti ndikuwonjezera zomwe zili hydroxpyl meth

Makhalidwe A Craceri:

Mu General Exprenterge Strider Engideer, mapangidwe olimba ndi C25. Malinga ndi mayeso oyambira, kuchuluka kwa simenti ndi 400kg, ulusi wophatikizika ndi 25kg / m3, gawo la mchenga ndi 40% ya madzi okwanira 8% ya kuchuluka kwa simenti. Chizindikiro cha konkriti mumlengalenga chimakhala ndi mphamvu pafupifupi masiku 28, ndipo konkriti wa pansi pamadzi wokhala ndi kutalika kwa 66.4MPA. Chiwerengero champhamvu chopanga mpweya ndi 84.8%, ndipo zotsatira zake zimakhala zodabwitsa.

1. Kuphatikiza kwa hydroxypropyl methylcellulose ali ndi mphamvu yobwezeretsa matope. Ndi kuwonjezeka kwa zomwe zili hydroxypropyl fithy fiber, nthawi yokhazikitsa matope imawonjezereka. Pankhani yofanana ndi cellulose yemweyo, marope omwe amapangidwa pansi pamadzi adzatenga nthawi yayitali kuti akhazikike. Izi ndizopindulitsa pamapulogalamu a konkire pansi pamadzi.

2. Zomwe zili ndi hydroxypypyl fityl fiber ndi madzi ofunikira matope adatsika koyamba kenako ndikuwonjezeka mwachiwonekere.

3. Matope atsopano a simenti osakanizidwa ndi HPMC ali ndi zinthu zabwino komanso pafupifupi zopanda magazi.

4. Kuwonjezera hydroxypropyl methyllulose pansi pamadzi osaphatikizidwa ndi simenti osakaniza, kuwongolera mlingo ndi kopindulitsa mphamvu. Pulogalamu yoyendetsa ndege imawonetsa kuti njira yamphamvu yopangira madzi ndi konkire ndi 84,8%, ndipo zotsatira zake ndizofunikira.

5. Kusandutsidwa kwamadzi kumathandizanso vuto la kuchuluka kwa madzi osakanizidwa, mwanjira ina kuphatikizika kwa matope osakanikirana kwathu nthawi zina kumachepetsedwa.

6. Pali kusiyana pang'ono pokhazikitsidwa pakati pa simenti ya simenti yotsutsana ndi hydroxypyllulose komanso zowoneka bwino, ndi kapangidwe kake kazidutswa kamenti sinasiyanitse. Zolinga zake zopangidwa pansi pamadzi kwa masiku 28 zimakhala zomera pang'ono. Cholinga chachikulu ndikuti kuwonjezera kwa cellulose kumachepetsa kwambiri kutaya simenti pothira madzi, komanso kumachepetsa miyala yamiyala ya simenti. Pa ntchitoyi, mothandizidwa ndi zomwe sizingafanane ndi kusabala pansi pamadzi, mlingo wa ethel ether uyenera kuchepetsedwa momwe angathere.
