塑料- 影響著每天的日常生活
就增長(zhǎng)速度而言,沒(méi)有哪一種用量相當(dāng)?shù)牟牧夏軌蚺c塑料相提并論。世界各地的塑料需求量增長(zhǎng)速度均高與各國(guó)國(guó)內(nèi)生產(chǎn)總值的增長(zhǎng)速度。究其原因,那就是如果我們想滿足日常生活需求,并且讓生活越來(lái)越舒適,塑料是我們的不二選擇。對(duì)于食品包裝和運(yùn)輸、房屋的建造和保溫、家用電器、交通或休閑活動(dòng)等領(lǐng)域的應(yīng)用,塑料都是首選材料。

美國(guó)三都坪TPV
優(yōu)勢(shì):
惡劣環(huán)境性能 :TPV零部件在-60度至135度的恒定溫度范圍(-81℉到275℉)無(wú)破裂或粘性。良好的耐熱老化結(jié)合良好的耐多種酸,堿及水溶液。 有些產(chǎn)品可以包:尼龍,金屬和各種聚烯烴。薄至0.5毫米包覆成型消除粘合劑,粘接劑和機(jī)械聯(lián)動(dòng)裝置。節(jié)約成本,鞏固和設(shè)計(jì)靈活性。
軟接觸美學(xué) :在干燥的握把絲般的感覺(jué),旋鈕和處理與熱塑性彈性體TPV牌號(hào)增加了客戶的吸引力和成本效益的市場(chǎng)價(jià)值為消費(fèi)和工業(yè)產(chǎn)品。
靈活性廣泛:三都坪TPV產(chǎn)品,從35A—強(qiáng)硬50D.一般用途等級(jí)適用于大多數(shù)應(yīng)用。 FDA的標(biāo)準(zhǔn),醫(yī)療等級(jí),阻燃等級(jí),符合UL的要求。
更容易設(shè)計(jì)復(fù)雜零件 :設(shè)計(jì)公差可2至3倍更精確比EPDM或氯丁橡膠。這使得產(chǎn)品設(shè)計(jì)人員創(chuàng)造出厚或薄墻部分,并簡(jiǎn)化多部分的設(shè)計(jì)。
1)注塑加工
TPV的熔體粘度比許多種普通熱塑性材料更大,在加工時(shí),需應(yīng)用較大的注料嘴、注料口、流道和澆口,還需要采用高的注射壓力和較快的注射速率,以提高充模速度和減少飛邊,此后在較高的壓力下有一個(gè)短的保持時(shí)間,使之足以將澆料口凍結(jié)。 注射螺桿的速度應(yīng)當(dāng)是100至200轉(zhuǎn)/分,背壓力在不需要混合時(shí)應(yīng)當(dāng)盡可能低。
2)擠塑加工
不需要真空定徑。建議采用長(zhǎng)徑比為28比1或更大比例的擠塑機(jī)。通常單段螺桿比為3比1左右,如果需要用篩網(wǎng)組合,可用20至60網(wǎng)目的篩網(wǎng)。最好將熔體溫度保持在規(guī)定范圍的下限,使擠塑產(chǎn)品的質(zhì)量最優(yōu)。
3)吹塑加工
TPV機(jī)械操作條件要求與注塑和擠塑所規(guī)定的相同。模具設(shè)計(jì)、型坯尺寸、加工周期時(shí)間、以及壁厚均勻等吹塑加工因素都與制件的幾何形狀有很大的關(guān)系。熔體加熱過(guò)度將使?fàn)可毂认陆?,?yīng)當(dāng)避免過(guò)熱。
