style="text-indent:25px">涂層被覆的前處理表面活化：這種活化是為了提高塑料的表面性能，也即在塑料表面生成一些極性基或加以粗化，以使涂料更易潤濕和吸附于制件表面。表面活化處理的方法很多，如化學(xué)品氧化法、火焰氧化法、溶劑蒸氣浸蝕法和電暈放電氧化法等。其中較普遍使用的是化學(xué)晶氧化處理法，此法常用的是鉻酸處理液，其典型配方為重鉻酸鉀4.5%，水8.0％，濃硫酸(96％以上)87.5%。有的塑料制品，如聚苯乙烯及ABS塑料等，未進(jìn)行化學(xué)品氧化處理時(shí)也可直接進(jìn)行涂層被覆。為了獲得高質(zhì)量的涂層被覆，也有用化學(xué)品氧化處理的，如ABS塑料在脫脂后，可采用較稀的鉻酸處理液浸蝕，其典型的處理配方為鉻酸420g／L，硫酸（比重1.83）200ml/L。典型的處理工藝為65℃70℃/5min10min，水洗凈，干燥。用鉻酸處理液浸蝕的優(yōu)點(diǎn)是無論塑料制品的形狀多復(fù)雜，都能處理均勻，其缺點(diǎn)是操作有危險(xiǎn)，并有污染問題。??惠州塑料杯定做廠家塑料制品要遵守國家規(guī)范。</p><div

style="text-indent:25px">塑料用作包裝材料，即食品包裝用塑料制品的出現(xiàn)是現(xiàn)代包裝技術(shù)發(fā)展的一個(gè)標(biāo)志，是30年來世界上發(fā)展較快、用量巨大的包裝新材料，它普遍用于食品包裝，大量取代了玻璃金屬、紙類等傳統(tǒng)包裝材料，成為食品銷售包裝較主要的包裝材料。塑料用于食品包裝，特別是熱成型制品方面的優(yōu)越性?；瘜W(xué)穩(wěn)定性較好：衛(wèi)生、安全。塑料能耐一般的酸、堿、鹽及油脂的腐蝕，大多數(shù)塑包裝材料可達(dá)到食品包裝的衛(wèi)生安全性要求。隨著現(xiàn)代科學(xué)技術(shù)的發(fā)展，塑料品種日益增多，極大促進(jìn)了新型復(fù)合材料的開發(fā)和包裝上的應(yīng)用。</p><p style="text-indent:25px">塑料制品的主要塑料-聚乙烯塑料的改性：聚丙烯塑料的使用性能存在一定的缺點(diǎn)，如耐寒性差、抗沖擊強(qiáng)度低、耐老化性差等。為了克服這些缺點(diǎn)，常常采用改性措施。1．共聚改性：與氯乙烯、丙烯酸等單體共聚，可改進(jìn)聚丙烯的耐寒性、易燃性、成型流動(dòng)性等。2．共混改性：和其它熱塑性塑料、彈性體共混，制備共混物，可改進(jìn)聚丙烯的耐寒性。3．填充——增強(qiáng)改性：添加填充材料和增強(qiáng)材料，提高聚丙烯在高溫時(shí)的剛性，并降低成型收縮率。4．拉伸改性：通過拉伸使分子定向，提高機(jī)械強(qiáng)度，如聚丙烯經(jīng)雙軸拉伸后，強(qiáng)度可以提高3倍。5．交聯(lián)改性：聚丙烯的線型結(jié)構(gòu)交聯(lián)成網(wǎng)狀結(jié)構(gòu)，可提高耐熱性、機(jī)械強(qiáng)度。塑料制品是不錯(cuò)的工業(yè)產(chǎn)品。</p><div

style="text-indent:25px">塑料制品的組成：塑料發(fā)泡劑是一種在一定溫度下可以氣化的低分子有機(jī)物，如二氯二氟甲烷；或者受熱時(shí)會(huì)分解出氣體的有機(jī)化合物。這些氣體留在塑料基體中便形成有許多細(xì)微泡沫結(jié)構(gòu)的泡沫塑料。常用的有偶氮化合物、亞硝基化合物等。著色劑用于塑料的著色。主要起美化、修飾作用。塑料制品中約有80%是經(jīng)過著色后制成之后制品的。潤滑劑是為了改善塑料加熱成型時(shí)的脫模性和提高制品的表面光潔度而加入的物質(zhì)。常用的潤滑劑有：硬脂酸及其鹽類、石蠟、合成蠟等。塑料制品比較方便使用?；葜菟芰媳ㄗ鰪S家</p><p style="text-indent:25px">塑料制品的應(yīng)用場景有很多。江門常見的塑料制品</p><p style="text-indent:25px">家電用塑料制品的成型加工方法主要有注塑成型、擠出成型、熱成型、中空成型、層壓成型、壓縮模塑、傳遞模塑、泡沫塑料成型、澆注成型、嵌鑄、封鑄等，其中以注塑成型為主。近年來，一些塑料加工新技術(shù)、新設(shè)備在家電塑料制品成型中得到大量應(yīng)用，如精密注塑、快速成型技術(shù)、熔芯注塑技術(shù)、氣輔/水輔注塑成型技術(shù)、電磁動(dòng)態(tài)注塑成型技術(shù)和覆膜注塑成型技術(shù)等。塑料制品的注塑加工技術(shù)精密注塑：可以保證制品在尺寸和重量方面具有高精度和高重復(fù)性。采用這一技術(shù)的注塑機(jī)可以實(shí)現(xiàn)高壓、高速注射。由于其控制方式通常為開環(huán)或閉環(huán)控制，因此可以對注塑工藝參數(shù)實(shí)現(xiàn)高精度控制。江門常見的塑料制品</p><p
