Freelancing is all about Connecting with multiple clients with a sole purpose – START WORKING for them for better paychecks. Here, arises the biggest CHALLENGE and it is finding the quality clients which have the capability of identifying trending and creative projects. Those projects may either be related to technology (like developing an application through Java, Angular JS, or any other language from the SCRATCH) or FAN-ANIMATED MUSIC creation. Indeed, there are many unknown PROS and CONS of freelancing but you can convert your existing CONS -> PROS by choosing the workload as per your ability. You can, again and again, work on the tasks which you really don’t like or choose those projects promisingly offering you a choice of freedom from mental and emotional stress. After you make a wiser choice, getting paychecks of 1500 or 2750 US Dollars for a few months of work won’t become challenging. Rather, a choice of BECOMING A BOSS or building global connections which invite a better lifestyle will respond favorably by removing the concept of MONOTONY permanently from your lives thereby inviting luxury and comfort.

2021年1月份,天盟公司接到莱州某特种纸业公司的委托,要求对其公司受损烘缸进行热喷涂技术修复,要求对其表面喷涂碳化钨陶瓷涂层,从而增强烘缸的防腐耐磨性能。
烘缸到厂之后,天盟公司技术人员对烘缸受损表面进行分析并制定热喷涂修复方案,采用超音速喷涂技术,在烘缸表面喷涂碳化钨陶瓷涂层,能有效提高烘干的耐高温性、绝缘性以及化学稳定性,延长烘缸的使用寿命。其主要工艺如下:
1、表面找平:烘缸的长时间使用,会产生局部磨损或腐蚀,有时会出现凹坑或疤块,需要提前磨平或者是补平,终待喷涂的工件表面应大致平滑、无凹坑、无凸起。
2、除油:如果工件表面粘连油脂,需要用清洗液除掉,晾干后在进入下一个环节。
3、喷砂除锈:喷砂应选用不含粉尘、有棱角、干燥、无杂质以及一定颗粒范围的砂粒。
4、喷涂:喷涂是整个工艺流程的重要环节,需要调整好喷涂设备的工艺参数,保证运行稳定;避免出现断弧情况;喷涂距离与角度要严格把控好;喷涂是遵循上下喷左侧移、分片完成的原则,避免出现漏喷情况。
5、预检查:对涂层的厚度、均匀度、外观是否有裂纹、是否有脱落等明显的外观现象进行检查。
6、封孔:对于防腐涂层,封孔这一工艺是很重要的,要选择具有渗透性号、耐高温、耐腐蚀等性能的封孔剂。
天盟公司专注于热喷涂技术服务,欢迎广大客户咨询。
