Udindo wa hydroxypropyl methylcellulose mumatope

Hydroxypropylmethylcellulose

Zoposa 95% za kalasi yomangahydroxypropyl methylcelluloseamagwiritsidwa ntchito mu matope a putty powder. ntchito zake ndi thickening, kusunga madzi ndi kumanga. Kusunga madzi kwa HPMC kumalepheretsa slurry kusweka chifukwa cha kuyanika mwachangu mukatha kugwiritsa ntchito, kumawonjezera mphamvu mutatha kuumitsa, ntchito yayikulu ndikusunga madzi, kukhuthala, ndi zotsatira zotsutsa-sagging. Itha kugwiritsidwa ntchito ngati zomatira mu pulasitala, gypsum, putty powder kapena zida zina zomangira kuti zithandizire kufalikira ndikutalikitsa nthawi yogwira ntchito; monga matailosi a ceramic, marble, mapulasitiki Kukongoletsa: Monga chowonjezera cha phala, chingathenso kuchepetsa kuchuluka kwa simenti; kwa matope odana ndi ming'alu, onjezerani polypropylene anti-crack fiber (PP fiber) muyeso yoyenera, kuti ikhalepo ngati mipiringidzo mumatope, kuti mukwaniritse zotsutsana ndi ming'alu. HPMC imangogwira ntchito yosungira madzi, kukhuthala ndi kutsutsa-sag.

1. Zomangamanga pulasitala matope

Kusungirako madzi ochuluka kungapangitse simenti kukhala ndi madzi okwanira, kuonjezera kwambiri mphamvu ya mgwirizano, ndipo nthawi yomweyo, kungathe kuonjezera mphamvu zowonongeka ndi kumeta ubweya, kupititsa patsogolo ntchito yomanga ndikuwongolera bwino ntchito.

2. Putty wosamva madzi

Mu putty, hydroxypropyl methylcellulose cellulose ether makamaka imagwira ntchito yosungira madzi, kugwirizana ndi kudzoza, kupewa ming'alu ndi kutaya madzi m'thupi chifukwa cha kutaya madzi ambiri, ndipo nthawi yomweyo kumawonjezera kumamatira kwa putty ndi kuchepetsa sag panthawi yomanga Phenomenon, kuti zomangamanga zikhale zosalala.

3. pulasitala pulasitala mndandanda

Pakati pa mankhwala gypsum mndandanda, hydroxypropyl methylcellulose mapadi efa makamaka amatenga udindo wa posungira madzi ndi kondomu, ndipo nthawi yomweyo ali ena retarding zotsatira, amene amathetsa mavuto a ng'oma akulimbana ndi kulephera koyamba mphamvu pa ntchito yomanga, ndipo akhoza anawonjezera maola ntchito.

4. Interface wothandizira

Amagwiritsidwa ntchito kwambiri ngati thickener, omwe amatha kupititsa patsogolo mphamvu zamakokedwe ndi kumeta ubweya, kukonza zokutira pamwamba, kukulitsa kumamatira ndi mphamvu zomangira.

5. Mtondo wotsekereza khoma wakunja

Munkhaniyi, hydroxypropyl methylcellulose cellulose ether makamaka imagwira ntchito yolumikizana ndikuwonjezera mphamvu, kupangitsa kuti ikhale yosavuta kuvala matope ndikuwongolera magwiridwe antchito. Wonjezerani nthawi yogwirira ntchito yamatope, onjezerani kuchepa ndi kukana kwa ming'alu, onjezerani khalidwe lapamwamba, ndikuwonjezera mphamvu zomangira.

6. Zomatira matailosi

Kusungidwa kwamadzi kwapamwamba sikuyenera kulowetsedwa kale kapena kunyowetsa matailosi ndi maziko, zomwe zingathe kupititsa patsogolo mphamvu zawo zomangira. Slurry ikhoza kukhala ndi nthawi yayitali yomanga, yabwino komanso yofananira, ndipo ndiyosavuta kumanga. Ilinso ndi kukana kwabwino kwa chinyezi.

7, wothandizira wokhotakhota, wolozera

Kuwonjezera kwahydroxypropyl methylcellulose cellulose etherzimapangitsa kuti zikhale zomangirira bwino m'mphepete, kuchepa pang'ono komanso kukana kuvala kwakukulu, zomwe zimateteza zinthu zoyambira ku kuwonongeka kwamakina ndikupewa kuwonongeka komwe kumachitika chifukwa cholowa mnyumba yonseyo. Chikoka.
