如何分辨管材优劣有六大秘籍 

                                                                           


在家装工程中,管材如何选购?如何判断管材的质量好坏?现在收罗汇聚了管材选购和辨别质量的秘籍,为您的爱家装修提供帮助。     

                                                                       
  一、是“捏”硬度。                                                    

                                                                          
PP-R管具有相当的硬度,随随便便可以捏变形的管,肯定不是PP-R管。

                                                    
  二、是“闻”气味。                                                 

                                                                
PP-R管主要材料是聚丙烯,好的管材没有气味,差的则有怪味,很可能是掺和了聚乙烯,而非聚丙烯。                                                            

                                                                        
  三、是“摸”质地。                                                         

                                                        

一般来说,颗粒粗糙的很可能掺和了杂质。                                  

                                                        
  四、是“看”颜色。                                                   

                                                                  
PP-R管主要有白灰绿几种,消费者往往认为白色才是的,其实颜色并非判断质量好坏的标准。                                                       

                                                              
  五、是“烧”烟嗅味。                                       

                                                                   
原料中混合了回收塑料和其他杂质的PP-R管会冒黑烟,有刺鼻气味。而好的材质燃烧后不仅不会冒黑烟、无气味,燃烧后,熔出的液体依然很洁净。                            

                                                                            
  六、是“砸”弹性。                                                        

                                                                          
好的PP-R管,“回弹性”好,容易砸碎自然不是好的PP-R管。但硬度强不等于弹性好,有些厂家通过加入过多碳酸钙等杂质来提高硬度,怎么都砸不碎,用久了容易脆裂。
