1 减低粘性、易于施工
经过增加各种修建专用羟丙基甲基纤维素商品，可制得低粘性和易于施工的石膏灰泥，在选用较低粘度等级的修建专用羟丙基甲基纤维素时，粘度程度相对下降而施工变得简单，不过，低粘度修建专用羟丙基甲基纤维素的保水才能较弱，需求调高增加量。
1 to reduce the viscosity, easy construction
By adding a variety of building products dedicated hydroxypropylmethylcellulose , low viscosity can be prepared by the construction of the gypsum plaster and easy , when using a low viscosity grade hydroxypropylmethylcellulose building dedicated , relatively lower degree of viscosity the construction easier, however , low water retention capacity building dedicated viscosity hydroxypropyl methyl cellulose is weak , you need to increase the dosage .
24 灰泥的增容率
对固定量的干砂浆来说，能制造出较高的湿灰泥体积经济效益更佳，能够经过增加多一些水份和气泡到达。但水份和气泡的量过多时，对强度有损。
2 mortar Capacity Rate
A fixed amount of dry mortar , it can produce a high volume of wet plaster better economies , by adding more water and the bubble reaches . However, excessive amounts of water and bubbles , on the strength detrimental . |
