淺談PP塑料板材和PVC板的兩者的區別

想必大家都知道pp板的耐酸堿程度、溫度和應用范圍和pvc作對比。

耐酸堿程度: PVC的耐酸堿程度比PP板會更好一些,但是質地較脆且硬,抗紫外線輻射,能長時間經 受住氣候變化,不易燃,有輕毒性。但是PP板是不防紫外線的,太陽光長時間照射會變色。

溫度區別: A、國產;PP的承溫范圍大概是0至80攝氏度,PVC的范圍是0至60攝氏度,CPVC這 種材質的承溫范圍是-40至95攝氏度。 B、進口德國“新美樂”品牌:PP的承溫范圍大概是0至100攝氏度左右,PVC的承溫 范圍是-40到95攝氏度。

應用范圍: A、PP板主要應用在耐酸堿設備,環保設備,廢水、廢氣排放設備、洗滌塔、無塵室、半 導體廠及其相關工業之設備,其中PP厚板材廣泛用于沖壓板,沖床墊板等。 B、PVC板是以PVC為原料制成的截面為蜂巢狀網眼結構的板材。PVC板主要應用于建 材、包裝、醫藥等諸多行業。比如建筑方面、電鍍設備、耐酸堿設備、工業排污設備、化工 行業等方面。PVC按照軟硬程度可分為軟PVC和硬PVC。

PP板是我們生活中常用到的板材,很多時候我們都需要對其進行塑料型加工。而選擇哪種方法要根據PP板零件的技術條件及不同的使用要求。

在實際生產中,盡管管件的形狀、尺寸及使用場合都是不同的,它的加工工序是相同的,分為幾個步驟。每一加工工序又可以通過不同的加工方法來實現。塑料性加工與板材塑料性加工相比,雖然從變形性質、變形特點等等多方面的特點來看,他們之間都有許多的相似之處,但在工藝方法、需要解決的工藝難點、工裝結構設計、工藝參數選擇以及防止產品生產質量缺陷兒采取的工藝措施等方面,都存在著很大的不同,都存在著不同的原因。
