環(huán)氧樹脂成型
注射成型方法,以異氰酸酯和聚醚制成聚氨酯半硬質(zhì)塑料的汽車保險(xiǎn)杠、翼子板、儀表板等。此法具有設(shè)備投資及操作費(fèi)用低、制件外表美觀,耐沖擊性好,設(shè)計(jì)靈活性大等優(yōu)點(diǎn),80年代發(fā)展很快。反應(yīng)注射成型還可制得表層堅(jiān)硬的聚氨酯結(jié)構(gòu)的泡沫塑料。為了進(jìn)一步提高制品剛性和強(qiáng)度,在原料中混入各種增強(qiáng)材料時(shí)稱為增強(qiáng)反應(yīng)注射成型,產(chǎn)品可作汽車車身外板、發(fā)動(dòng)機(jī)罩。開發(fā)的品種有環(huán)氧樹脂、雙環(huán)戊二烯聚合物、有機(jī)硅樹脂和互穿聚合物網(wǎng)絡(luò)等。
注塑成型過程
反應(yīng)注射成型要求各組分一經(jīng)混合,立即快速反應(yīng),并且物料能固化到可以脫模程度。因此,要采用專用原料和配方,有時(shí)制品還需進(jìn)行熱處理以改善其性能。成型設(shè)備的關(guān)鍵是混合頭的結(jié)構(gòu)設(shè)計(jì)、各組分準(zhǔn)確計(jì)量和輸送。此外,原料貯罐及模具溫度控制也十分重要。
傳統(tǒng)罐子對(duì)比優(yōu)勢(shì)如何?
1、傳統(tǒng)罐子和設(shè)備對(duì)比,在上料上新設(shè)備比傳統(tǒng)要快捷,方便;
2、傳統(tǒng)罐子不宜清洗,新設(shè)備在維護(hù)上比傳統(tǒng)的節(jié)約成本;
3、上料速度可以電腦控制,比傳統(tǒng)的要精確,壓力大小可以調(diào)控;
4、同時(shí)可以多臺(tái)設(shè)備供料。
