GAFLOON（卡弗龙）PPR管的接口采用热熔技术，管子与管件之间完全融合，是目前给水产品成熟、、实用的技术，所以一旦安装打压测试通过，不会再漏水，可靠度极高。水管在房子中犹如人身体上的大动脉，承担着压力（水压）、输送着生命必需品（水），采用的PPR水管，用得安全、用得放心、用的更是健康和安全，卡弗龙承诺质保终身（七十年）。

The interface of Gafloon PPR pipe adopts hot-melt technology, and the pipe and fittings are fully integrated. It is the most mature, safe and practical technology for water supply products at present. Therefore, once the installation and pressure test are passed, there will be no water leakage and the reliability is very high. The water pipe in the house is like the artery of human body, which bears the pressure (water pressure) and conveys the necessities of life (water). With high-quality PPR water pipe, it is safe to use, safe to use, and healthy and safe to use. Caffron promises to guarantee your life (70 years), so that you will not worry about it.

“隐蔽工程”是一个非常重要的问题，现代装修水管都是采用埋墙式施工，如果水管渗漏和爆裂将带来难以弥补的后果。Gafloon卡弗龙管道，为保证质量，严格检测，欢迎来咨询。

"Hidden engineering" is a very important problem. Modern decoration water pipes are built with buried walls. If the water pipes leak and burst, it will bring irreparable aftermath. Gafloon Pipe and Fitting, in order to ensure the quality, strict testing, welcome to seek advice from us.

塑料管材越来越多的开始走进我们的生活，新型环保塑料管材的广泛使用，掀起了一场替代传统建材的革命。而塑料管材因为具有水流损失小、节能环保、竣工便捷等优点，成为现在管道的主力军。主要用于给水管道施工的ppr管材不仅适用于热水管道，也可以适用纯净饮用水管道。

More and more plastic pipes h***e entered our lives. The wide use of new environmental protection plastic pipes has set off a revolution of replacing traditional building materials. Because of its advantages of ***all water loss, energy s***ing and environmental protection, and convenient completion, plastic pipe has become the main force of the pipeline. PPR pipe mainly used in water supply pipeline ctruction is not only suitable for hot water pipeline, but also for pure drinking water pipeline.

随着工业的发展，酸雨，硫污染日趋严重，且型材在贮存和运输过程中可能与硫磺，硫化物相接触，故发生硫化污染的可能性较大。硫污染主要是

Pb2﹢+S2-→PbS(黑)

2S2﹣+PbCl?→Pb(ClS)?(红褐色)

反应形成的物质为黑色或红裼色，可导致白色材料变色，故使用铅盐稳定剂型材易发生硫污染。镉类稳定剂属***产品，如在管材中使用，在硫化物环境中易发生如下反应：

S2-+Cd2+→CdS↓(***)

会导致管材泛黄，因此镉类稳定剂，很少被使用。

由群青引发的变色(在含铅盐稳定剂配方中)

群青是含多而具有特殊结构的硅酸铝。不经特殊处理的群青耐碱性耐热性和耐酸性差。当管材被酸雨淋后，在强烈的阳光照射下，在管材表面残存的酸雨与群青作用形成“HS ˉ”离子，该离子溶于水，进一步水解形成Sˉ与型材中存在的Pb2+作用，形成沉淀物而使管材表面着色从而导致“硫化”污染现象 。

Pb2﹢+S?ˉ→PbS↓(结晶形：蓝色)

(无定形：黑色)

新型增韧材料对白色型材耐候性、变色性影响

CPE做PVC增韧材料目前还被绝大多数厂家所使用，但CPE氯化聚乙烯，由于其结构的特点，在光热、氧等作用下易分解变色，使管材变黄。此外，更为主要的是CPE分解产生HCL易与铅盐稳定剂反应成PbCl?。在硫污染环境之下易生成Pb(ClS)?和PbS，会使管材变为红褐色和黑色。

因此建议：

① 群青必需要进行处理琮，具有耐碱性耐热性和耐酸性

② 不采用含硫化物的稳定剂

③ 采用金红石型钛

④ 采用质量优级的CPE
