那么影响石塑电梯门套质感的因素有哪些?

来源:http://m.nthly.cn/ 浏览:0发表时间:2023-08-23
一、石塑电梯门套表面侵蚀现象:用手触摸石塑电梯门套表面,如果是粗糙面,石塑电梯门套可能是被酸侵蚀所造成的,影响使用寿命和美观度。
1、 Surface erosion phenomenon of stone plastic elevator door jambs: Touch the surface of stone plastic elevator door jambs with your hand. If it is a rough surface, the stone plastic elevator door jambs may be caused by acid erosion, affecting their service life and aesthetics.
二、白华或晶化:检查是否为白华,在填缝处或石塑电梯门套表面一些白色粉末,很容易用手清除。
2、 White Hua or Crystallization: Check if it is white Hua. There is some white powder on the surface of the filling joint or stone plastic elevator door cover, which is easy to remove by hand.
三、石塑电梯门套表面全面性黄化:全面性黄化没有区域性,可能是使用之表面处理剂黄变后所产生。
3、 Comprehensive yellowing on the surface of stone plastic elevator door jambs: Comprehensive yellowing is not regional and may be caused by the yellowing of the surface treatment agent used.

四、石塑电梯门套水斑:石塑电梯门套表面有颜色加深现象,检查是否为水斑,可先用清水湿润石材表面,使用广用试纸,测其PH值,若是碱性(广用试纸呈蓝色),表示为水斑,若不是,则有可能是油脂污染。若是碱性水斑污染,则即使使用瓦斯喷枪加热表面,也很难烘干。若只是一般水分渗透所造成的,很容易干燥消失。
4、 Stone plastic elevator door cover water stains: There is a color deepening phenomenon on the surface of the stone plastic elevator door cover. To check if it is a water stain, wet the stone surface with clean water first, use a universal test paper to measure its pH value. If it is alkaline (the universal test paper is blue), it indicates a water stain. If it is not, it may be contaminated by grease. If alkaline water stains are contaminated, even if a gas spray gun is used to heat the surface, it is difficult to dry. If it is only caused by general water infiltration, it is easy to dry and disappear.
电梯门套材料中越来越多的承包商都开始选用这种材料来做电梯套工程,但是对于刚刚接触石塑电梯门套的客户来说,并不清楚怎样区分手里的石塑电梯门套质量是否合格达标。有了以上了解,在采购线时,相信大家就能够对如何辨别仿大理石电梯门套线的质感有了一定的把我。
More and more contractors are choosing this material for elevator door covers, but for customers who have just come into contact with stone plastic elevator door covers, it is not clear how to distinguish whether the quality of the stone plastic elevator door covers in the product meets the standards. With the above understanding, I believe everyone will have a certain understanding of how to distinguish the texture of imitation marble elevator door cover lines when purchasing.
