</p> <p> <br /> 江西復(fù)合塑料配件批發(fā)廠家塑料配件產(chǎn)品電鍍的麻點(diǎn)來源比較復(fù)雜，但大部分來源于四個(gè)地方：基體、化學(xué)鍍前、鍍銅、鍍鎳。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江耐油塑料配件誠信廠家,塑料配件" src="https://tyunfile.71360.com/UploadFile/wanhejmzc/637330066310097656/8426805.png"></div><p> 螺紋連接是使用較廣的可拆聯(lián)接方式，但用于塑料制品聯(lián)接時(shí)有許多特點(diǎn)和難點(diǎn)，以下技術(shù)問題必須注意： </p> <p> 1、塑料配件上的螺紋螺牙強(qiáng)度較差，成型困難。 </p> <p> 2、注塑成型塑料配件上螺紋孔或螺釘孔的周邊存在熔合縫。該處材料強(qiáng)度比無縫區(qū)低。 </p> <p> 3、塑料聯(lián)接件在緊固后有較高殘余應(yīng)力，蠕變使聯(lián)接件的尺寸和聯(lián)接強(qiáng)度不穩(wěn)定 </p> <p> 4、螺紋連接的塑料配件之間緊固力松弛之后，使制品對(duì)氣體或液體的密封不可靠。因此需增加柔性或彈性密封墊。 </p> <p> 另外用金屬螺釘聯(lián)接塑料配件時(shí)，要充分考慮材料的熱膨脹問題，在一些濕度大耐腐蝕性要求高的場(chǎng)合，可使用塑料螺紋連接，效果不錯(cuò)。由于金屬螺栓的強(qiáng)度比塑料配件大得多，一般用較小直徑的螺栓（4～22㎜），若采用空心螺栓，直徑可為6～50㎜。整個(gè)過程配件較少，整體外觀較好，拆裝方便。 </p> <p> <br /> </p><p> </p> <p> <br /> </p> <p> 粘接操作中基本的工藝流程如下： </p> <p> ①清潔塑料配件先用肥皂水清洗整個(gè)塑料配件，干燥后，再用**塑料清潔劑進(jìn)行清潔。 </p> <p> ②變形修整塑料配件如有變形，可以使用紅外線燈加熱變形部位及其周圍，使其回復(fù)到原來的狀態(tài)。 </p> <p> ③裂紋處鉆孔對(duì)于塑料配件上的裂紋，應(yīng)使用鉆頭在裂紋末端鉆一個(gè)孔，防止裂紋進(jìn)一步發(fā)展。 </p> <p> ④打磨Ⅴ形槽用砂磨機(jī)在損傷處打磨出V形槽，并用砂紙修復(fù)平整。 </p> <p> ⑤背面加固損傷嚴(yán)重時(shí)，需利用黏合劑和輔助材料共同增強(qiáng)損傷處的背面強(qiáng)度。 </p> <p> ⑥正面修補(bǔ)在塑料配件正面磨好的修理部位處涂上黏結(jié)促進(jìn)劑，將調(diào)配好的黏合劑涂在修補(bǔ)部位及其周邊，并按規(guī)定進(jìn)行硬化處理。 </p> <p> ⑦打磨用砂紙對(duì)粘接部位進(jìn)行打磨，打磨時(shí)用力不能過大，以防塑料配件變形。 </p> <p> <br /> 通過表面處理的方法提高塑料配件表面的表面張力，提高涂層的附著。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="黑龍江耐油塑料配件誠信廠家,塑料配件"

如今，塑料原料的使用已經(jīng)由普通塑料擴(kuò)展到跟高、更耐沖擊性更好的復(fù)合材料或者塑料合金了，可以預(yù)見，隨著塑料材質(zhì)及其成型技術(shù)與工藝的提高，塑料配件在汽車、摩托車工業(yè)的應(yīng)用將更加普遍，必然會(huì)引來汽摩模具的大發(fā)展。隨著汽車產(chǎn)業(yè)的愈演愈烈，隨之帶動(dòng)的汽車模具行業(yè)也逐漸升溫，相關(guān)**表示，汽車、摩托車工業(yè)每年有700多億的模具需求量，而我們國家大型精密模具的制造能力還遠(yuǎn)遠(yuǎn)不夠，目前我國高中檔轎車的覆蓋件模具幾乎全部依靠進(jìn)口。大中型內(nèi)外飾件塑料模具也是有很大的需求量。發(fā)展科技含量高的大型精密汽車、摩托車覆蓋件模具和大中型內(nèi)外飾件塑料模具是今后我國汽車、摩托車模具的重要工作。 </p> <p> <br /> 根據(jù)產(chǎn)品大小，確定塑料配件主體壁厚。江西復(fù)合塑料配件批發(fā)廠家</p><p style="text-indent:25px">凡塑料配件較高、較大的尺寸，應(yīng)選用較小的脫模斜度。黑龍江耐油塑料配件誠信廠家</p><p> 塑件的壁厚過大，不僅會(huì)因用料過多而增加成本，且也給工藝帶來一定的困難，如延長(zhǎng)成型時(shí)間（硬化時(shí)間或冷卻時(shí)間）。對(duì)提高生產(chǎn)效率不利，容易產(chǎn)生汽泡，縮孔，凹陷； </p> <p> 塑件壁厚過小，則熔融塑料在模具型腔中的流動(dòng)阻力就大，尤其是形狀復(fù)雜或大型塑件，成型困難，同時(shí)因?yàn)楸诤襁^薄，塑件強(qiáng)度也差。塑件在保證壁厚的情況下，還要使壁厚均勻，否則在成型冷卻過程中會(huì)造成收縮不均，不僅造成出現(xiàn)氣泡，凹陷和翹曲現(xiàn)象，同時(shí)在塑件內(nèi)部存在較大的內(nèi)應(yīng)力。 </p> <p> 設(shè)計(jì)塑件時(shí)要求壁厚與薄壁交界處避免有銳角，過渡要緩和，厚度應(yīng)沿著塑料流動(dòng)的方向逐漸減小。 </p> <p> <br /> 黑龍江耐油塑料配件誠信廠家</p><p
