管材環(huán)向彎曲剛度是指管道抵抗環(huán)向變形的能力，簡(jiǎn)稱(chēng)環(huán)剛度。環(huán)向彎曲剛度是塑料管材抵抗環(huán)向變形能力的重要指標(biāo)。塑料排水管道的比較大和**小覆土厚度通常受外壓荷載的控制，其比較大變形應(yīng)控制在5%范圍內(nèi)。上海市市政工程研究院通過(guò)對(duì)塑料管材的砂箱加載試驗(yàn)，測(cè)試結(jié)果表明，當(dāng)塑料排水管材的環(huán)向彎曲剛度為8KN/㎡時(shí)，其技術(shù)經(jīng)濟(jì)綜合性能**為適宜。因?yàn)樯跋浼虞d試驗(yàn)當(dāng)塑料管材的變形率為5%時(shí)，只要管道兩側(cè)回填黃砂（粗）的密實(shí)度符合要求，其外荷載作用可相當(dāng)管頂比較大覆土厚度4--5m,一般應(yīng)能滿(mǎn)足排水工藝設(shè)計(jì)的管道埋深要求。因此規(guī)定管道位于道路車(chē)行道下，其環(huán)剛度不宜小于8KN/㎡；對(duì)住宅小區(qū)及其它地段的排水管道，因地面荷載小，管頂覆土也淺，故可選擇環(huán)向彎曲剛度較低的塑料管材，但不宜小于4KN/㎡。

在擠出機(jī)熔融擠出過(guò)程中將螺筒溫度分別設(shè)定為180—220℃（可根據(jù)不同原料做工藝溫度調(diào)整），在該工作溫度下，擠出機(jī)將充分熔化的樹(shù)脂擠出。 </p> <p> 1.4.真空成型： </p> <p> 一擠出機(jī)擠出來(lái)的樹(shù)脂熔化料，在工作溫度180℃的條件下，通過(guò)真空成型模具將熔化料定型成空心塑料異型矩管，然后輸送到冷卻機(jī)。 </p> <p> 1.5.冷卻： </p> <p> 該流程中分兩種冷卻方式：（1）通過(guò)噴淋水箱將注塑機(jī)傳遞的異型矩管進(jìn)行噴淋冷卻，一般是冷卻后溫度為50℃，（主要是指矩形管壁表層溫度）。（2）通過(guò)傳遞流程讓矩型管自然冷卻，這是冷卻機(jī)與纏繞成型機(jī)設(shè)定一定的距離原故。 </p> <p> <br /> </p><p> 產(chǎn)品： </p> <p>

1、耐腐蝕、抗老化性能好：由于HDPE管的原材料為高分子成份的聚乙烯組成，它能有效的抵抗酸、堿、鹽等介質(zhì)的腐蝕和未經(jīng)處理的工業(yè)廢水和生活污水的侵蝕，同時(shí)其抗老化性能也比PVC管等性能好。 </p> <p> 2、柔韌性好：HDPE管屬柔性管，延伸性能好，故較能適應(yīng)地基較差條件下的施工及地基沉降，特別是在沿海地區(qū)，地基均較差，沉降嚴(yán)重，該種管材能夠大幅度適應(yīng)不均勻沉降。 </p> <p> 3、質(zhì)量輕、安裝方便：減輕了勞動(dòng)強(qiáng)度，縮短了施工工期。 </p> <p> 4、強(qiáng)度高，使用壽命長(zhǎng)：由于HDPE管是采用***高密度聚乙烯在熱熔狀態(tài)下整體制成的管道，其整體性好，化學(xué)性質(zhì)穩(wěn)定，強(qiáng)度高，使用壽命長(zhǎng)，可長(zhǎng)達(dá)50年以上。 </p> <p> <br />

（1）從材質(zhì)上來(lái)比較，混凝土材質(zhì)的耐腐蝕、耐磨等性能遠(yuǎn)低于HDPE材質(zhì)。 </p> <p> （2）混凝土管在華東地區(qū)的使用壽命為10-15年，而HDPE雙壁纏繞管在50年以上。 </p> <p> （3）纏繞管的水阻系數(shù)為0.0078-0.0092，一般設(shè)計(jì)取0.01，混凝土管的水阻系數(shù)為0.013-0.014，比纏繞管高30%-40%。也就是說(shuō)流量和流速低30%-40%。實(shí)際證明，同等流量時(shí)，纏繞管可以換用低一個(gè)的管材口徑，如可用DN500mm的纏繞管代替DN600mm的混凝土管。 </p> <p> （4）纏繞管是環(huán)保產(chǎn)品，可***回收，混凝土管則不能。 </p> <p> （5）纏繞管施工方便，砂石基礎(chǔ)，即時(shí)開(kāi)挖即時(shí)回填，重量公為同等水泥管的1/8，無(wú)需大型吊車(chē)等工具，施工周期短，日常維護(hù)費(fèi)用低，綜合造價(jià)與水泥管相當(dāng)。 </p> <p> <br />
