無(wú)法實(shí)現(xiàn)局部鍍鉻。為解決現(xiàn)有技術(shù)問(wèn)題，開(kāi)發(fā)了耐UV免噴涂PC材料，并對(duì)采用該材料的零件進(jìn)行了反復(fù)的實(shí)驗(yàn)驗(yàn)證，結(jié)果滿足產(chǎn)品各項(xiàng)技術(shù)要求，終得以成功應(yīng)用。該材料的開(kāi)發(fā)應(yīng)用，給一些有特別裝飾、功能設(shè)計(jì)的產(chǎn)品提供了一個(gè)全新的材料解決方案，同時(shí)也拓寬了PC材料在外部燈具領(lǐng)域的應(yīng)用。原材料基礎(chǔ)樹(shù)脂PC，抗UV助劑，主抗氧劑，輔助抗氧劑，加工助劑。制備方法把經(jīng)過(guò)干燥的所有原材料按組成比例混合后，用雙螺桿加料器連續(xù)均勻加入螺桿直徑為35mm且長(zhǎng)徑比為36的雙螺桿擠出機(jī)主機(jī)筒中，主機(jī)筒分段控制溫度，從加料口至機(jī)頭出口的溫度分別為230℃、250℃、300℃、300℃、300℃、290℃、290℃，雙螺桿轉(zhuǎn)速為300r/min，擠出料條經(jīng)過(guò)水槽冷卻后切粒得到改性PC組合物產(chǎn)品?？筓V助劑選擇了苯并三唑類及氰基丙烯酸酯類2種抗UV吸收劑，抗氧劑選擇了受阻酚類主抗助劑，亞磷酸酯類輔抗助劑，加工助劑選擇了酯類助劑。為摸索出佳配方，確定了3種配方組合。利用上述改性透明PC組合物注塑好樣板，立即放入玻璃干燥器中，在室溫放置至少24h后進(jìn)行性能測(cè)試。同時(shí)，利用上述改性透明PC材料注塑成型為汽車外部燈具外面罩，用于相應(yīng)的實(shí)驗(yàn)。該改性PC組合物可以直接注塑成型。</p><p> 對(duì)于現(xiàn)在賞心悅目的汽車零部件，這是特別具有吸引力的，但是在表面電鍍的時(shí)候會(huì)降低材料本身的沖擊強(qiáng)度，因此可以根據(jù)適當(dāng)要求采用彈性體與PC進(jìn)行共混改性，由于彈性體能夠降低內(nèi)應(yīng)力開(kāi)裂，且韌性不會(huì)收電鍍的影響而**降低，所以電鍍PC材料是具有非常大的開(kāi)發(fā)空間，同時(shí)表面金屬化的PC塑料還可以作為屏蔽電磁波材料，應(yīng)用于計(jì)算機(jī)中。PC綜合性能優(yōu)異，在醫(yī)療設(shè)備中的應(yīng)用也隨處可見(jiàn)，但是由于其耐化學(xué)性相對(duì)較差，因此在化學(xué)藥劑作用下易引起內(nèi)應(yīng)力開(kāi)裂，如PC在人工透析器、人工肺等醫(yī)療器械中應(yīng)用，要解決高溫消毒導(dǎo)致裂紋的老化現(xiàn)象，若要客服這些困難，PC在醫(yī)療器械中應(yīng)用可迅速擴(kuò)大。PC片材特別適宜于制作眼鏡鏡片，在PC分子鏈中引入硅氧基團(tuán)，可以提高其硬度及耐擦傷性。PC作為高折射率塑料，用于制作耐高溫光學(xué)纖維的芯材，在PC分子鏈中的C―H鏈被C―F鏈所取代，對(duì)可見(jiàn)光的吸收則減少，能有效降低傳遞途中的信號(hào)損失。另外PC有良好透光性，在透明窗材、高層建筑幕墻、機(jī)場(chǎng)和體育場(chǎng)館透明建筑材料等方面應(yīng)用非常普遍并具有潛力，今后重點(diǎn)是提高表面硬度和抗靜電性。★相關(guān)說(shuō)明：正規(guī)的渠道進(jìn)貨，可提供COA報(bào)告,MSDS,SGS環(huán)保報(bào)告,UL黃卡及物性加工參數(shù)。PC

補(bǔ)縮作用小易出現(xiàn)真空泡或表面出現(xiàn)縮凹，保壓壓力過(guò)大，澆口周圍易產(chǎn)生較大的內(nèi)應(yīng)力。在實(shí)際加工中，常以高料溫，低保壓的辦法來(lái)解決。保壓時(shí)間的選擇應(yīng)視制品的厚薄，澆口大小，模溫等情況而定，一般小而薄制品不需很長(zhǎng)的保壓時(shí)間，相反，大而厚的制品保壓時(shí)間應(yīng)較長(zhǎng)。保壓時(shí)間的長(zhǎng)短可通過(guò)澆口封口時(shí)間的試驗(yàn)予以確定。5.注射速度對(duì)PC制品的性能無(wú)十分明顯的影響，除了薄壁，小澆口，深孔，長(zhǎng)流程制品外，一般采用中速或慢速加工，好是多級(jí)注射，一般采用慢-快-慢的多級(jí)注射方式。6.模具溫度模溫控制：85~120℃，一般控制在80-100℃就可以，對(duì)形狀復(fù)雜，較薄，要求較高的制品，也可提高到100-120℃，但不能超過(guò)模具熱變形溫度。模溫高以減少模溫及PC料溫的差異，可以降**件的內(nèi)應(yīng)力。7.螺桿轉(zhuǎn)速與背壓由于PC熔體粘度較大，從有利塑化、排氣以及塑機(jī)的維護(hù)保養(yǎng)的角度看，為防止螺桿負(fù)荷過(guò)大，對(duì)螺桿的轉(zhuǎn)速要求不可太高，一般控制在30-60r/min為宜，而背壓控制在注射壓力的10-15%之間為宜。8.助劑的使用PC在注塑過(guò)程中要嚴(yán)格控制脫模劑的使用，同時(shí)再生料的使用不能超過(guò)三次，使用量應(yīng)為20%左右。9.模具要求1)設(shè)計(jì)盡可能粗而短，彎曲位少的流道。PC
