近幾年，隨著社會經(jīng)濟的高速發(fā)展，城市改造的加速進展，PVC管材這些年發(fā)展也非?？臁ＭǔVC管材它被***的運用于給排水管道，因此近幾年pvc管材廠家也越來越多，作為消費者如何選擇質量pvc管材，就顯得尤為重要，具體要從哪些方面考慮呢？ </p> <p> 1、要看產(chǎn)品上標識是否齊全，PVC管材上應有生產(chǎn)廠名或商標，生產(chǎn)日期，產(chǎn)品名稱，規(guī)格尺寸（S或en），執(zhí)行標準號等，字跡要清晰，并檢查標識是否與實際相符。 </p> <p> 2、選擇光澤均勻一致，內外壁光滑、平整，無氣泡、凹陷、雜質等影響表面性能缺點的PVC管材給水管。 </p> <p> 3、應當夠買同一品牌的PVC管材與管件，因不同品牌的產(chǎn)品原料可能不一樣，對PVC管材管件連接會產(chǎn)生不利因素。 </p> <p> 4、當我們肉眼看起來都比較漂亮的時候，這個時候，就要看PVC管材內在質量了，可以把管子豎起來，然后自然摔下去，看管子是否會摔壞，一般情況下，好的管材不會壞。 </p><p> 找pvc管材廠家需要注意哪些問題 </p> <p> 選標識：看看該品牌是否具有榮譽稱號，這些榮譽是國家對品牌美譽度和質量的綜合評價，必須經(jīng)過嚴格審核才能獲得。具有這些稱號的企業(yè)都比較珍視這些榮譽，在產(chǎn)品質量上也更加有保障。 </p> <p> 看管材：管材的內外表面應該光滑、平整，無凹陷、氣泡等表。 </p> <p> 面缺點，這樣才能保證水流暢通、不積垢。看管件：質量好的品牌除了保證產(chǎn)品品質外，尤為關注細節(jié)，消費者選購時可以注意管件彎頭是否采用大弧度彎位設計以減少水錘形成，是否有45度倒角設計以方便熔接。 </p> <p> 看服務：一般大品牌管材都有完善的售后服務，以保障消費者利益，服務好的品牌通常還配有產(chǎn)品服務卡。從某些角度上講，售后服務越好的品牌，質量就越好，否則售后服務會很麻煩。 </p> <p> 聞味道：選購管材時，可以拿來相同品牌的管件(必須挑一整包未開封的管件)，撕開塑料袋聞一聞，如有輕微刺鼻氣味，不能買。因為真正的pvc管材、管件原材料——聚丙烯是無毒無味的;而質量一般的管材管件會選用聚丙烯回收下腳料，甚至摻入聚乙烯和滑石粉，這樣的產(chǎn)品質量靠不住。 </p><div style="width:100%;text-align: center;"><img

社會經(jīng)濟的發(fā)展伴隨著PVC管材的迅速發(fā)展，每年增加率到達8%，而每年需要增加率2%在塑料管材中。PVC管材用量一向遙遙**，它被***的運用于給排水管道，因此近幾年pvc管材廠家也越來越多，作為消費者如何選擇質量pvc管材，要從哪些方面考慮呢？ </p> <p> <br /> </p> <p> 1、選擇色澤基本均勻一致，內外壁光滑、平整，無氣泡、凹陷、雜質等影響表面性能缺點的PVC管材給水管。 </p> <p> 2、要看產(chǎn)品上標識是否齊全，PVC管材上應有生產(chǎn)廠名或商標，生產(chǎn)日期，產(chǎn)品名稱，規(guī)格尺寸（S或en），執(zhí)行標準號等，管件上應有產(chǎn)品名稱（PVC）、公稱外徑、管系列S等，字跡要清晰，并檢查標識是否與實際相符應有產(chǎn)品名稱（PVC）、公稱外徑、管系列S等，字跡要清晰，并檢查標識是否與實際相符。 </p> <p> 3、應當買同一品牌的PVC管材與管件，因不同品牌的產(chǎn)品原料可能不一樣，對PVC管材管件熔接會產(chǎn)生不利因素，長期使用中會引起熔接處滲漏。 </p> <p> <br /> 仙桃PVC管材廠家批發(fā)</p><p style="text-indent:25px">黃石PVC管材價格</p><p> PVC管材優(yōu)勢 </p> <p> 在通用樹脂生產(chǎn)中，以PVC樹脂耗乙烯量比較低，生產(chǎn)成本也比較低。國內生產(chǎn)每噸PVC需耗乙烯0.5314噸，而每噸聚乙烯平均耗乙烯1.042噸，國內每噸PVC樹脂的乙烯耗量比聚乙烯少消耗約50%。而生產(chǎn)PVC用的原料氯氣，是平衡生產(chǎn)燒堿產(chǎn)生氯氣的重要途徑，燒堿是國民經(jīng)濟必不可少的十分重要原料。另外，從塑料制品角度看，PVC與各種助劑相容性好，在生產(chǎn)管材中可加入大量低廉的填料，使生產(chǎn)成本**降低。 </p> <p> PVC管材與金屬管材相比，生產(chǎn)每立方米PVC和生產(chǎn)每立方米鋼及鋁計算，鋼的能耗為316KJ/m3，鋁的能耗是619KJ/m3，PVC的能耗為70KJ/m3，即鋼的能耗是PVC的4.5倍，鋁的能耗是PVC的8.8倍。而生產(chǎn)PVC管的加工能耗也*為同口徑金屬管材的三分之一。同時由于PVC管壁光滑，不結腐蝕瘤，輸水效率高，用于輸液可節(jié)電20%左右。 </p> <p> <br /> </p> <p> PVC管材有很好的力學性能，且具備極好的耐腐蝕性，使用過程中重量輕，安裝方便，不需維護，而使用鋼鐵作公用工程的下水管道，在使用過程中由于易腐蝕，必須經(jīng)常涂敷涂料，維護費用高。一般建筑及公用工程用金屬管道20年左右就需更換，而作用加工良好的PVC管道，使用壽命長達50年等。因此，PVC管材是一種生產(chǎn)成本低、強度高，耐腐蝕的良好塑料制品。黃石PVC管材價格</p><p
