花紋鋁卷是我們經常使用的產品,然而有些用戶購買的花紋鋁卷脆是怎么回事?其實,鋁卷脆主要是由于一些鋁卷生產廠家生產技術原因,生產工藝不達標,天然輸出的裝飾鋁卷很容易出現脆化現象,
Patternedaluminumcoilisaproductweoftenuse.However,whatisthematterwiththecrispnessofpatternedaluminumcoilpurchasedbysomeusers?Infact,thecrispnessofaluminumcoilismainlyduetotheproductiontechnologyofsomealuminumcoilmanufacturers,andtheproductionprocessisnotuptothestandard.Thenaturaloutputdecorativealuminumcoilispronetoembrittlement,
具體原因主要集中在以下三個方面:
Thespecificreasonsaremainlyconcentratedinthefollowingthreeaspects:
1.模具截面設計不合理:內部配筋和界面角度分布不當會導致應力集中現象的存在,導致鋁脆卷曲圖案,需要改進設計,消除界面的直角和銳角。
1.Unreasonabledesignofdiesection:improperdistributionofinternalreinforcementandinterfaceanglewillleadtotheexistenceofstressconcentration,resultinginthecrispyandcurlypatternofaluminum,soitisnecessarytoimprovethedesignandeliminatetherightangleandacuteangleofinterface.
2.模具壓頭壓力不足:模具壓頭的壓力直接由模具的壓縮比決定,尤其是模具的直線段長度。壓頭的壓縮比過小或平截面過短都會造成產品不致密,影響鋁盤管的物理性能。
2.Insufficientpressureofdiehead:thepressureofdieheadisdirectlydeterminedbythecompressionratioofdie,especiallythelengthofstraightsectionofdie.Ifthecompressionratiooftheheadistoosmallortheflatsectionistooshort,theproductwillnotbecompact,whichwillaffectthephysicalpropertiesofthealuminumcoil.
三。分流桿遇到壞:在這種情況下,應適當增加肌肉和外表面強化和鋼筋長度的融合,或增加壓縮比,模頭壓力的變化可以調節長度變化的連續模頭流阻,在模具設計階段選擇不同的壓縮比可以改變擠壓壓力,但注意鼻子擠出機螺桿壓縮比壓縮比,還可以通過改變配方,調整擠出工藝參數,增加穿孔板,改變熔體壓力大小。
Three.Thesplitterbarisdamaged:inthiscase,thefusionofmuscleandoutersurfacereinforcementandsteelbarlengthshouldbeincreasedappropriately,orthecompressionratioshouldbeincreased.Thechangeofdieheadpressurecanadjusttheflowresistanceofcontinuousdieheadwiththechangeoflength.Choosingdifferentcompressionratiointhediedesignstagecanchangetheextrusionpressure,butpayattentiontothecompressionratioofnoseextruderscrew,andtheextrusioncanalsobeadjustedbychangingtheformulaProcessparameters,increaseperforationplate,changemeltpressure.
上述模式鋁盤管產品常見的脆弱的原因,當用戶購買產品時,必須選擇那些信譽高的鋁卷生產廠家,企業的實力購買自己的產品,為了避免因為購買產品的質量不符合標準,并推遲了他們的正常生產。
