曾經(jīng)材料行業(yè)的幾篇關(guān)于pc材料杯子安全性的文章，引起了眾多網(wǎng)友的恐慌，很多人都查閱了一堆資料，但是都得不到一個詳細(xì)的解釋，現(xiàn)在關(guān)于pc材料的杯子裝開水有沒有毒的疑惑，UTPE彈性體平臺**在線給大家科普一下。首先認(rèn)識一下pc材料是什么？PC就是聚碳酸酯，是比較常見的塑料材料之一，材料其實本身是無毒的，一般用于制造奶瓶、太空杯等，但因其含有雙酚A而備受爭議。理論上只要在制作PC的過程中雙酚A完全轉(zhuǎn)化成塑料結(jié)構(gòu)，制品就不會存在雙酚A，也就也就無毒的，對健康沒有威脅。假若有少量雙酚A沒有轉(zhuǎn)化成PC的塑料結(jié)構(gòu)，則可能會滲入食物或飲品中威脅使用者，特別是青少年的健康安全。pc材料的杯子裝開水一般是沒問題的，為什么？因為一般的PC材質(zhì)的塑料杯可以耐-45℃-135℃的溫度，開水一般都在這個區(qū)間內(nèi)，所以比較安全。但這是材料的物理性能，只是說這種材料在這種溫度下使用是不會開裂熔化。但是當(dāng)我們從食品安全角度出發(fā)會發(fā)現(xiàn)，隨著溫度愈高，PC中殘留的雙酚A釋放量會愈多，而且速度也愈快，所以PC之所以會存在健康威脅是因為在高溫時它會釋放雙酚A，那么這讓人“聞之色變”的雙酚A到底是何方神圣呢?雙酚A(BPA)在工業(yè)上常被用來合成PC和環(huán)氧樹脂等材料。沙伯基礎(chǔ)（原GE）抗沖擊性，照明工具。</p><div

回此必須以較高溫度注塑（270－320℃之間），相對來說料溫調(diào)節(jié)范圍較窄，工藝性不如PMMA。注射壓力對流動性影響較小，但因粘度大，仍要較大注射壓力，相應(yīng)為了防止內(nèi)應(yīng)力產(chǎn)生，保壓時間要盡量短。收縮率不大，尺寸穩(wěn)定，但產(chǎn)品內(nèi)應(yīng)力大，易開裂，所以宜用提高溫度而不是壓力去改善流動性，并且從提高模具溫度、改善模具結(jié)構(gòu)和后處理去減少開裂的可能；當(dāng)注射速度低時，澆口處易生波紋等缺陷，放射嘴溫度要單獨控制，模具溫度要高，流道、澆口阻力要小。3、PET的工藝特性PET成型溫度高，且料溫調(diào)節(jié)范圍窄（260－300℃），但熔化后流動性好，故工藝調(diào)節(jié)性差，且往往在射嘴中要加防延流裝置。其機械強度及性能注射后不高，必須通過拉伸工序和改性才能改善性能。模具溫度的準(zhǔn)確控制，是防止翹曲、變形的重要因素，因此建議采用熱流道模具；模具溫度要高，否則會引起表面光澤差和脫模困難。綜上所述，我們可以列出注塑工藝參數(shù)表，供大家注射時參考。五、透明塑料件的缺陷和解決辦法由于篇幅關(guān)系，這里只討論影響產(chǎn)品透明度的缺陷，其缺陷大概有以下幾項：1、銀紋：由充模和冷凝過程中，內(nèi)應(yīng)力各向異性的影響，垂直方向產(chǎn)生的應(yīng)力，使樹脂發(fā)生流動上取向。揚州哪家PC哪里的便宜</p><p
