2.3 作為載體的應(yīng)用聚酰胺胺(PAMAM)樹狀分子中有大量的含 N 的官能團(tuán)(伯胺,叔胺,酰胺)，上海改性聚酰胺廠家推薦,一層一層有規(guī) 律地排列,隨著代數(shù)的增加而增加.而且聚酰胺胺(PAMAM)樹狀分子的內(nèi)部具有可變的空腔 , 外部具有大量的活性官能團(tuán),所以可以在聚酰胺胺(PAMAM)樹狀分子的內(nèi)部引入催化劑的活性中心，上海改性聚酰胺廠家推薦,在空腔內(nèi)部完成整個(gè)催化過程,同時(shí)也可以利用端基的活性,將催化劑的活性中心聯(lián) 結(jié)在分子的外部，上海改性聚酰胺廠家推薦.

在PA加入30%的玻璃纖維，PA的力學(xué)性能、尺寸穩(wěn)定性、耐熱性、耐老化性能有明顯提高，耐疲勞強(qiáng)度是未增強(qiáng)前的2.5倍。玻璃纖維增強(qiáng)PA的成型工藝與未增強(qiáng)時(shí)大致相同，但因流動(dòng)較增強(qiáng)前差，所以注射壓力和注射速度要適當(dāng)提高，機(jī)筒溫度提高10-40℃。由于玻纖在注塑過程中會(huì)沿流動(dòng)方向取向，引起力學(xué)性能和收縮率在取向方向上增強(qiáng)，導(dǎo)致制品變形翹曲，因此，模具設(shè)計(jì)時(shí)，澆口的位置、形狀要合理，工藝上可以提高模具的溫度，制品取出后放入熱水中讓其緩慢冷卻。另外，加入玻纖的比例越大，其對注塑機(jī)的塑化元件的磨損越大，較好是采用雙金屬螺桿和機(jī)筒。</p><p
