DOCUMENT PREVIEW4.1.2 B类型的硫磺灰浆
此产品是硫磺和颗粒级配小于0,315毫米添加剂的混合物。根据本标准附录而测得的强度至少等于55Mpa。
根据法国标准(NF P 18-406)压碎试验的合格表现是,与参考方法相比较(端面砂轮法),加工强度100Mpa的混凝土在30分钟之后才被压碎。
4.2 表面待加工产品的准备
把事先搅拌均匀的表面产品注入3.5条所述容器中,直至达到其容积的四分之三处。把温度控制器调到140摄氏度所对应的刻度。用搅拌勺不时搅拌混合物直到其完全融解,一旦达到适当的粘稠度,再到温度调节器调到120摄氏度和140摄氏度1之间的区域。
4.3 操作模式
有必要的话,要去除平齐面边缘的飞边毛刺。
仔细地擦拭要切削的表面。
有需要的话,对试块进行快速烘干,以便带加工表面能更好地附合。
在表面加工工具底盘的表面和倾斜表面涂上一层薄薄的油。
在摄氏120度至140度之间用搅拌勺把混合物搅拌均匀,并一次就提取出需要数量的产品,灌倒加工工具底槽并使之分别均匀。
通过垂直导向装置,使试块慢慢落下2。当产品凝固时,用手或者锤子敲击产品,使其脱离工具底槽。
再次重复以上步骤,以加工试块的另一个受荷载面。
仔细检查表面加工层和原来的表层是否完全粘合,用弯曲手指敲击表层各处,如果表层敲击的声音听起来很空洞,用榔头将其敲碎,再重新开始之前的步骤。
注意事项:1. 要经常搅动混合物,使混合均匀并避免其在容器底部沉积。
2. 如果每个步骤衔接很紧凑,最好交替使用两个带温度控制器的容器。
3. 一定要避免液面的大辅减少,否则将有硫蒸汽泄出并有自燃的风险。
1. 严格遵循温度的要求,可以减少硫蒸汽泄漏和大气污染的风险。
2. 表层的平均厚度因温度和混合物成分比例以及施加在产品试块上的作用力不同而不同。
— 温度和产品组成成分尽量保持稳定;
— 试块下落要慢而有规律。
只要表层一接触到产品,速度就应该减到0,以使产品受的压力只是表层本身的自重。为了避免任何液体外溅的危险,试块一定不能冲掉下。

NOTES
- Member countries may choose, to be included in their national standards, the sizes which are required to meet their demand.
- For the angles so chosen, only thicknesses which can be rolled in their mills to meet the demand of the users may be selected from the list of thicknesses corresponding to equal angles in table 1.
- The sectional area has been calculated using the formula
S = [l/2 A - l) + 0,214 6 (rroot² - 2rtoe²)] × 1/100
where
S is the sectional area, in square centimetres;
l is the thickness, in millimetres;
rroot is the root radius, in millimetres;
rtoe is the toe radius, in millimetres;
A is the leg length, in millimetres.
- Mass is calculated on the basis of density of steel of 7,85 kg/dm³.
