查询词典 poriness

The method of the study is using Metallographical examination, surface roughness and poriness of the copper coating ware. Results show that different structures of the coating reflect different combination mechanism.

采用Olympus GX71金相显微镜对涂层界面进行金相组织观察并拍照；采用光切法测定了涂层的表面粗糙度；采用贴滤纸法测定了涂层的孔隙率。

The fracture reasons of high strength PC steel wire are analyzed, it's considered that center segregation, central cavitation, poriness and inclusion are the metallurgical reasons which lead to the facture of PC steel wire and in the rolling process, differential coping quality, microcrack caused by surface defect, abnormal microstructure caused by burnt and improper cooling velocity, the ears on the head of the wire, overlapping of the wire rod itself are the main reasons which lead to the facture of PC steel wire. At the same time, inappropriate pickling, differential phosphorization quality, the bad heat treatment quality, the generation of crack in the improper drawing and transverse crack caused by abnormal laying of the drawing die are also the reasons of the cracking of PC wire.

对高强度PC钢丝断裂原因进行了分析，认为连铸坯的中心偏析、中心缩孔、疏松和夹杂是导致PC钢丝断裂的冶金原因；轧制过程中，较差的修磨质量、表面缺陷导致的微裂纹，过烧以及不适当的冷却速度导致的非正常显微组织，盘条头部的耳子、盘条本身折叠是导致PC钢丝断裂的主要原因；同时，不恰当的酸洗、较差的磷化及热处理质量、不适当拉丝裂纹的产生、拉拔模具安放不正导致的横裂也是PC钢丝断裂的原因。

There was an obvious phenomenon of mechanical occlusion on the cold spray coating interface, and the rolled coating had the phenomenon of metallurgical bonding; The structure of cold-sprayed coating is dense. The poriness of the cold-sprayed coating gradually reduce as the coating's thickness increase.

结果 涂层界面形貌的不同反映出两种涂层的结合机理不尽相同，冷喷涂层界面出现明显的机械咬合现象，而轧制涂层以冶金结合为主；冷喷涂层组织致密，孔隙率随着喷涂厚度的增加逐渐降低；冷喷涂层的表面粗糙度高于轧制覆铜板，有必要对其进行一道轧制处理，改善涂层表面平整度。

The technique comprises the steps as follows: using the waste filtered mud of the sugar-refinery as the material to generate gas which is dehydrated till the water content is less than and equal to 30 percent and through distribution (clay used for of 70.00 to 85.0 percent, dehydrated filtered mud of the sugar-refinery of 15.0 to 30.0 percent, intensifier carboxymethyl cellulose or propyloic fibrin is 0.1 percent of the total dosage of the below material), performaing, moulding with high temperature (800 to 1200 DEG C, 20 to 180min) and acquiring the multi-hole porcelain granule with 20 to 30 percent of poriness, 10 to 20 percent of water absorbing capacity and 1.5 to 7.5/MPa of cylinder pressing intensity.

一种糖厂滤泥生产多孔陶粒技术，是用糖厂废弃物滤泥为发气原料，经脱水至含水≤30％，经配料(陶瓷用黏土70.0～85.0％，糖厂脱水滤泥15.0～30.0％，增强剂羧甲基纤维素或羧乙基纤维素为上述原料总量的0.1％)、制坯、高温(800~1200℃，20～180min)成型，得到孔隙率20~30％、吸水率10~20％、筒压强度1.5~7.5/MPa的多孔陶粒。
