HPMC mu Wet Mortars
JINJI® Hydroxypropyl Methyl Cellulose (HPMC) ndi polima yopangidwa ndi cellulose ether yochokera ku cellulose, polima yachilengedwe yochokera ku linter ya thonje yoyenga.
HPMC ikhoza kupititsa patsogolo mgwirizano ndi kusunga madzi kwa osakaniza a Spray mortar.
Mlingo wosunga madzi ndi index yofunikira ya Spray Mortar. Ngakhale zigawo zina za matope ndi konkriti ndizofanana, zimagwira ntchito mosiyana. Kawirikawiri, konkire imatsanuliridwa mu konkire ndi ntchito yamatabwa yomwe imasunga madzi ambiri. Mtondo nthawi zambiri umagwiritsidwa ntchito pamadzi otsekemera madzi, ndipo chinyezi mumatope chimatayika mosavuta kapena chimatuluka mumlengalenga, choncho kusunga madzi kwa matope kumakhala kofunika kwambiri kuposa konkire.
Chifukwa HPMC timapitiriza kugwirizana wa kutsitsi matope ndi kusunga madzi, akhoza kusintha cohesiveness matope, kuchepetsa magazi mlingo wa matope pamlingo wakutiwakuti, koma kusintha fluidity wa utsi matope mkati mwapadera mlingo osiyanasiyana; Komabe, kuchuluka kwa Hydroxpropyl Methyl Cellulose kumapangitsa kuti matope osakaniza amadziphatikize kwambiri, omwe amachepetsa kusungunuka kwa matope ndikupanga matope kukhala ovuta kupanga.
HPMC ikhoza kuonjezera mphamvu yomangirira yamatope osakanikirana ndi madzi.
Kwa pulasitala matope, mphamvu ya mgwirizano ndi chizindikiro chofunikira. Nthawi zambiri, pulasitala matope amafuna ntchito yabwino. Kuti apange yunifolomu matope wosanjikiza pa yomanga pamwamba. Mphamvu yolumikizana mwamphamvu ya matope imatha kupangitsa kuti matope ndi tsinde la pansi likhale logwirizana kwambiri, ndipo kugwiritsidwa ntchito kwa nthawi yayitali sikungayambitse kusweka ndi kugwa.
Ma cellulose ether ndi ma hydration particles amapanga filimu yopyapyala ya filimu ya polima yokhala ndi kusindikiza komanso kuteteza kutayika kwa madzi, ndi kusunga madzi abwino, kotero kuti imakhala ndi chinyezi chokwanira kuonetsetsa kuti simenti ndi hydration ndi mphamvu zowonjezera komanso kulimbitsa mphamvu zomangira. wa phala. Kumbali inayi, Hydroxpropyl Methyl Cellulose imathandizira kugwirizanitsa kwa matope opopera kuti atsimikizire kuti mapulasitiki ake ndi abwino komanso osinthika, amachepetsa kupsinjika pakati pa matope opopera ndi mawonekedwe amtundu wa gawo lapansi, ndikupititsa patsogolo luso lolumikizana ndi matope.
Ndibwino kuti panthawi yokonzekera, HPMC imasakanizidwa mumatope opopera ngati njira yothetsera vutoli m'malo mophatikizana mwachindunji ndi mawonekedwe a ufa.
Yoyamba imakhala ndi zotsatira zabwino pakusunga madzi, kulumikizana, komanso makina amakina amatope opopera. Pamene zosinthidwa za Hydroxpropyl Methyl Cellulose zili mu 0.01% ~ 0.04%, mlingo wosungira madzi wa HPMC mu mawonekedwe a yankho ndi 1.4% ~ 3.0% apamwamba kuposa a HPMC ufa mumatope opopera. Choncho, HPMC wothira mu mawonekedwe a yankho ali ndi zotsatira zabwino pa kusintha madzi posungira wa kutsitsi matope.
