HPMC na Wet Mortars
JINJI® Hydroxypropyl Methyl Cellulose (HPMC) bụ ihe na-abụghị ionic cellulose ether polima dabere na cellulose, a eke polima ewepụtara site nụchaa owu linter.
HPMC nwere ike imeziwanye njikọta na njigide mmiri nke ngwakọta ngwa agha Spray.
Ọnụego njide mmiri bụ ihe nrịbama arụmọrụ dị mkpa nke Spray Mortar. Ọ bụ ezie na ụfọdụ ngwa ngwa na kọnkịtị bụ otu, ha na-arụ ọrụ dị iche iche. N'ozuzu, a na-awụsa konkịtị n'ọrụ sink na osisi nke na-ejigide ọtụtụ mmiri. A na-ejikarị ngwa agha eme ihe n'elu ebe mmiri na-amịkọrọ mmiri, na mmiri dị na ngwa ngwa na-adị ngwa ngwa na-efunahụ ma ọ bụ na-awụpụ n'ime ikuku, ya mere njigide mmiri nke ngwa agha ahụ na-adị mkpa karịa nke simenti.
Ihe mere na HPMC enhances anọgidesi nke ịgba ngwa agha bụ mmiri-ejigide, nwere ike melite cohesiveness nke ngwa agha, ibelata ọbara ọgbụgba ọnụego nke ngwa agha ruo n'ókè ụfọdụ, ma melite fluidity nke ịgba ngwa agha n'ime a kpọmkwem usoro onunu ogwu nso; Otú ọ dị, nnukwu ọdịnaya nke Hydroxpropyl Methyl Cellulose na-eme ka mmiri mmiri mmiri na-ejikọta ọnụ, nke na-ebelata mmiri nke ngwa agha ahụ ma mee ka ngwa agha ahụ sie ike ịrụ.
HPMC nwere ike iwelie ike njikọta nke ngwa agha agwakọtara mmiri.
Maka plasta ngwa agha, ike nkekọ bụ ihe ngosi dị mkpa. N'ikwu okwu n'ozuzu, plasta ngwa agha chọrọ ịrụ ọrụ nke ọma. Iji na-etolite a edo ngwa agha oyi akwa na-ewu elu.

The cellulose ether na hydration particles na-eme ka oyi akwa nke ihe nkiri polymer nwere mmetụta mkpuchi ma na-egbochi mmiri mmiri, na-ejigide mmiri dị mma, nke mere na ọ nwere mmiri zuru ezu iji hụ na hydration na ike mmepe nke ciment ma melite ike njikọ. nke mado. N'aka nke ọzọ, Hydroxpropyl Methyl Cellulose enhances cohesiveness nke spraying ngwa agha iji hụ na ọ dị mma plasticity na mgbanwe, na-ebelata slips nchegbu n'etiti ịgba ngwa ngwa na mkpụrụ ihe atụ interface, na n'ihu mma interface bonding ike nke ngwa agha.
