1.PE管在搬運(yùn)時(shí)，不得拋、摔、滾、拖；在冬季搬運(yùn)時(shí)應(yīng)小心輕放。采用機(jī)械設(shè)備吊裝搬運(yùn)時(shí)，必須用非金屬繩吊裝； </p> <p> 2.管材運(yùn)輸時(shí)，應(yīng)放置在帶擋板的平底車(chē)上或平坦的船艙內(nèi)，堆放時(shí)不得有可能損傷的尖突物。并應(yīng)采用非金屬繩捆扎、固定，以及有防曬、防雨淋措施； </p> <p> 3.管材應(yīng)存放在通風(fēng)良好的庫(kù)房或棚內(nèi)，堆放時(shí)應(yīng)遠(yuǎn)離熱源，嚴(yán)禁與油類(lèi)或化學(xué)品混合存放，場(chǎng)地應(yīng)有防火措施； </p> <p> 4.PE管材應(yīng)水平堆放在平整的支撐物或地面上。當(dāng)直管采用三角形式堆放或兩側(cè)加支撐保護(hù)的矩形堆放時(shí)，堆放高度不宜超過(guò)1.5m；當(dāng)采用分層貨架存放時(shí)，每層貨架高度不宜超過(guò)1m，堆放總高度不宜超過(guò)3m。 </p> <p> 5.管材這堆放時(shí)應(yīng)根據(jù)不同規(guī)格尺寸和不同類(lèi)型分別存放； </p> <p> 6.在戶外臨時(shí)存放時(shí)，要有遮蓋物。云南PE管材廠原態(tài)HDPE的外表呈乳白色.</p><div style="width:100%;text-align: center;"><img style="max-width: 640px;

</p> <p> （2）電熔連接：電熔連接時(shí)應(yīng)保證電熔工具連接正確，通電電流、通電時(shí)間的設(shè)置應(yīng)符合電熔配件要求。電熔承插面要求潔凈，銷(xiāo)銑兩端面垂直接合要好，用刀刮除電熔面的氧化層，并使電熔面打毛，增加接觸面。管道插入前要標(biāo)志好插入長(zhǎng)度位置，保證足夠長(zhǎng)度，保證電熔連接面積，增強(qiáng)連接接頭的質(zhì)量。鞍型電熔連接同樣要清去表面，并要求上緊管道平整固定螺絲，使接觸面吻合。

4.吹掃口應(yīng)設(shè)在開(kāi)闊地段，并采用加固措施；排氣口應(yīng)進(jìn)行接地處理。吹掃時(shí)應(yīng)設(shè)安全區(qū)域，吹掃出口嚴(yán)禁站人。 </p> <p> 5.吹掃氣體壓力不應(yīng)大于0.3MPa。吹掃氣體流速不宜小于20m/s，且不宜大于40m/s。 </p> <p> 6.每次吃掃PE管的長(zhǎng)度，應(yīng)根據(jù)吹掃介質(zhì)、壓力、氣量來(lái)確定，不宜超過(guò)500m。 </p> <p> 7.當(dāng)目測(cè)排氣無(wú)煙塵時(shí)，應(yīng)在排氣口設(shè)置白布或涂白漆木靶板檢驗(yàn)，5min內(nèi)靶上無(wú)塵土、塑料碎屑等雜物為合格。因?yàn)榕盼塾肞E管材的特點(diǎn)所以它是新型材料的優(yōu)先選擇。云南PE管材廠</p><p

一、PE管材外表面有劃痕。原因：定徑套、支撐板或密封圈上附有沙石。解決方法：清理定徑套、支撐板或密封圈。 </p> <p> <br /> </p> <p> 二、管材表面出現(xiàn)波紋。原因：冷卻不充分，密封圈尺寸不合適，形成震動(dòng)現(xiàn)象。解決方法：增加定徑套進(jìn)水量或增加口摸與定徑套之間的距離。檢查真空槽密封圈尺寸是否小，如果小，更換或適當(dāng)降低一節(jié)真空槽真空度，增加第二節(jié)真空槽真空度。 </p> <p> <br /> </p> <p> 三、表面有麻點(diǎn)(主要是內(nèi)壁)不光亮。原因：熔體溫度不合適或原料有問(wèn)題，原料中含有雜質(zhì)，口摸與芯摸間內(nèi)壁清理不干凈，局部溫度過(guò)高導(dǎo)致老化。解決方法：檢查原料，清理干凈或過(guò)渡一段時(shí)間，檢查溫度傳感器。 </p> <p> <br /> 德宏P(guān)E管件生產(chǎn)廠家</p><p
