HDPE是一種非常常見的材料,在建筑中常見到,而且hdpe給水管具有優(yōu)良的耐腐蝕性、較好的衛(wèi)生性能、使用壽命高、強度高、耐高溫等特點,現(xiàn)在和大家講解講解HDPE給水管與PE給水管之間的區(qū)別. </p> <p> 1、這里的高低壓主要指的是生產(chǎn)工藝的反應(yīng)條件,也就是一個是高壓工藝,一個是低壓工藝. </p> <p> 2、密度的不同,一個高，昆明PE給水管管材,一個低 ; </p> <p> 3、性能不同: (a) LDPE要軟一些, HDPE會硬一些; (b) LDPE透明度好, HDPE差 ;(c) LDPE容易變形，昆明PE給水管管材,強度差, HDPE 強度好; (d) LDPE的軟化點低,耐溫差, HDPE耐溫要好一些主要應(yīng)用: LDPE 主要用于薄膜應(yīng)用, 透明度好, 加工性能優(yōu)良, 但機械性能差 HDPE有很多應(yīng)用:拉絲（就是編織袋的纖維），昆明PE給水管管材,注塑（各種日用品）,吹膜（也就是薄膜應(yīng)用）,中空（吹塑成型,如一些PE的瓶子）. </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height:

若是讓PE給水管的缺點一直存在顯然會影響其正常使用效果和使用壽命，因此還是要對其就進(jìn)行修復(fù)，若是給水管的外壁損壞部位呈現(xiàn)管壁破碎或長0.1m以內(nèi)孔洞時，應(yīng)用刮刀將破碎的管壁或孔洞完全剔除，剔除部位周圍0.05m以內(nèi)用環(huán)已酮清理干凈。 </p> <p> PE給水管的受損位置刷耐水性能好的塑料粘合劑，再從相同管材相應(yīng)部位取下相當(dāng)損壞面積2倍的弧形板，內(nèi)壁涂粘合劑扣貼在損壞部位，用鉛絲包扎固定。如果外壁有肋，那就是將損壞部位周圍0.05m以內(nèi)的肋去除，刮平不帶肋跡，再以相同方法補救，使得給水管恢復(fù)正常，能夠在給水系統(tǒng)中發(fā)揮重要作用。 </p><div

8、壓力規(guī)定不同 </p> <p> ① PVC給水管道的壓力規(guī)定： </p> <p> PVC給水管道所示的壓力均表示為公稱壓力，用Mpa表示 </p> <p> 給水管材的公稱壓力規(guī)定為：0.6Mpa、0.8Mpa、1.0Mpa、1.25Mpa、1.6Mpa等5種。 </p> <p> 同等規(guī)格管材的公稱壓力的大小一般以管材的壁厚來劃分。 </p> <p> ② PE給水管試驗壓力 </p> <p> PE給水管試驗壓力值要求規(guī)范要求： </p> <p> 冷水管試驗壓力，應(yīng)為管道系統(tǒng)設(shè)計工作壓力的1.5倍，但不得小于1.0Mpa，時間不少于1小時。 </p> <p> 熱水管試驗壓力，應(yīng)為管道系統(tǒng)設(shè)計工作壓力的2.0倍，但不得小于1.5Mpa，時間不少于1小時。 </p> <p> PE給水管耐壓范圍有0.6Mpa、0.8Mpa、1.0Mpa、1.25Mpa、1.6Mpa等5種。 </p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="昆明PE給水管管材"
