Kufunika kowonjezera hydroxypropyl methylcellulose (hpmc) ku matope ndi malonda ochokera ku gypsum!

Mu simenti matope ndi gypsum-zochokera ku gyproxpyl, hydroxypropyll methylculose makamaka gawo la kusungidwa kwamadzi ndikukula, komwe kumatha kukonza zokongoletsera ndi kukana kosakanikirana kwa slurry. Zinthu monga kutentha kwa mpweya, kutentha ndi kuthamanga kwa mphepo kumakhudza madzi osinthika mu matope a simenti ndi gypsum. Chifukwa chake, nthawi zosiyanasiyana, pali zosiyana zina mumadzi zosungidwa ndi ma hydroxypropyl owonjezera. Mu zomanga zina, kuchuluka kwa madziwo kumatha kusinthidwa ndikukulitsa kuchuluka kwa HPMC yowonjezeredwa. Kusunga kwamadzi kwa methyl cellulose ether kutentha kwambiri ndi chizindikiro chofunikira kusiyanitsa mtundu wa methyl cellulose ether.

Zabwino kwambiri hydroxpyl methylcellulodose zotsatizana zimatha kuthana bwino ndi vuto la kusungidwa kwamadzi pamtenthedwe kwambiri. Mu nyengo zotentha kwambiri, makamaka m'malo otentha ndi owuma ndi zomangamanga zowonda m'mbali mwa dzuwa, hpmc zapamwamba kwambiri zimafunikira kukonza chitetezo chamadzi cha slorry.

HPMC yapamwamba kwambiri, yofanana bwino kwambiri, methoxy ndi hydroxyprovoy amagawika ma atomu am'madzi, kuti madzi aulere amathetsa madzi oyambitsidwa ndi kutentha kwanyengo komanso kukwaniritsa kusungidwa kwamadzi. Madzi amafunika kuti azitha kugwiritsa ntchito zinthu zina ngati simenti ndi gypsum. Kuchuluka kwa hpmc koyenera kumapangitsa madzi patatenga nthawi yayitali kuti alolere makonzedwe ndi kuuma popititsa patsogolo.
Kuchuluka kwa hpmc kumafunikira kuti mupeze mphamvu yokwanira yamadzi kutengera:
1. Kuyamwa kwa maziko osanjikiza

2. Kapangidwe ka matope

3. Kukula kwa matope

4. Kufuna kwa Matope

5. Kukhazikitsa nthawi ya chinthu

Hydroxypypypyl ya methylcellulose ikhoza kukhala yolumikizidwa bwino komanso yolumikizidwa bwino matope a simenti ndi gypsum, ndikukulitsa tinthu tokhazikika, ndipo chinyontho m'munsi chimamasulidwa pang'onopang'ono kwa nthawi yayitali. , ndipo hydration zikachitika ndi zinthu za avorganiyambo, potero, zikuwonetsetsa kuti pali mphamvu komanso kulimbikitsa mphamvu ya zinthuzo.
chithunzi

Chifukwa chake, mu mamangidwe otentha ndi nthawi yotentha, kuti tikwaniritse zinthu zosungidwa pamadzi, ndikofunikira kuwonjezera zinthu zapamwamba za HPMC m'magawo okwanira malinga ndi njira, kuchepetsedwa, kuwonongeka, ndikugwetsa kozizira kwambiri. Zimawonjezeranso zovuta zomanga antchito. Kutentha kwa kutentha kumachepa, kuchuluka kwa HPMC kumatha kuchepetsedwa pang'onopang'ono, ndipo madzi omwewo atha kukwaniritsidwa.
