花紋鋁卷發(fā)脆的主要原因是什么?

來源:http://www.kangyanghua.com/ 發(fā)布時(shí)間:2021-02-19

花紋鋁卷是我們經(jīng)常用的產(chǎn)品,不過有些用戶買到的花紋鋁卷發(fā)脆是怎么回事?其實(shí)鋁卷發(fā)脆主要還是因?yàn)橛械膹S家生產(chǎn)技術(shù)原因?qū)е碌?,生產(chǎn)技術(shù)不過關(guān),自然產(chǎn)出的花紋鋁卷就容易有發(fā)脆現(xiàn)象、
Patterned aluminum roll is a product we often use, but what's the matter with the crispy hair of patterned aluminum roll bought by some users? In fact, the crispness of aluminum coil is mainly caused by the production technology of some manufacturers. If the production technology is not up to standard, naturally produced patterned aluminum coil is prone to crispness
鋁卷生產(chǎn)廠家分析具體原因主要集中在以下三個(gè)方面:
According to the analysis of aluminum coil manufacturers, the specific reasons mainly focus on the following three aspects:
一.口模截面設(shè)計(jì)不合理:內(nèi)筋的分布和交界面角度的處理不當(dāng)就會(huì)會(huì)造成應(yīng)力集中現(xiàn)象存在,從而導(dǎo)致花紋鋁卷發(fā)脆,需要改進(jìn)設(shè)計(jì)和消除交界面處的直角和銳角。
1、 Unreasonable design of die section: improper distribution of inner ribs and interface angle will cause stress concentration, which will lead to embrittlement of patterned aluminum. It is necessary to improve the design and eliminate the right angle and acute angle at the interface.


二.模頭壓力不足:模頭處壓力大小是直接受模具的壓縮比,特別是模具平直段的長度來決定的。模頭的壓縮比太小或平直段太短都會(huì)造成制品不致密,影響花紋鋁卷物理性能。
2、 Insufficient die head pressure: the pressure at the die head is directly determined by the compression ratio of the die, especially the length of the straight section of the die. If the compression ratio of die head is too small or the straight section is too short, the product will not be compact and the physical properties of patterned aluminum coil will be affected.
三.分流筋匯合不良:對于這種情況,應(yīng)適當(dāng)增加筋與外表面、筋與筋匯流處的長度,或者增大壓縮比來解決,模頭壓力的改變可以通過改變模頭平直段長度來調(diào)整流料阻力,在模具設(shè)計(jì)階段可選擇不同的壓縮比來改變擠出壓力,但注意機(jī)頭壓縮比要與擠出機(jī)螺桿的壓縮比相適應(yīng),還可以通過改變配方,調(diào)整擠出工藝參數(shù),增加多孔板來改變?nèi)垠w壓力的大小。
3、 Poor convergence of splitter bars: in this case, it is necessary to increase the length of bars and outer surface, bars and bars confluence, or increase the compression ratio to solve the problem. The change of die head pressure can be adjusted by changing the length of straight section of die head. In the die design stage, different compression ratio can be selected to change the extrusion pressure, but the compression ratio of die head should be consistent with that of extruder screw According to the compression ratio, the melt pressure can also be changed by changing the formula, adjusting the extrusion process parameters and increasing the porous plate.
以上是花紋鋁卷成品常見的發(fā)脆原因,用戶在購買產(chǎn)品時(shí),一定要選擇那些信譽(yù)度高,實(shí)力過硬的企業(yè)來選購自己的產(chǎn)品,避免因?yàn)橘I到質(zhì)量不達(dá)標(biāo)的產(chǎn)品,而耽誤了自己正常的生產(chǎn)。
The above are the common reasons for the embrittlement of patterned aluminum coil products. When purchasing products, users must choose those enterprises with high reputation and strong strength to buy their own products, so as to avoid delaying their normal production because they buy products with substandard quality.
