近年來(lái)，鋁板市場(chǎng)的需求越來(lái)越大，市面上也出現(xiàn)很多新的鋁板廠家，可是由于技術(shù)不過(guò)關(guān)，沒有生產(chǎn)經(jīng)驗(yàn)，生產(chǎn)出的鋁板不合格，產(chǎn)品質(zhì)量不過(guò)關(guān)，導(dǎo)致鋁板發(fā)脆，那么是什么導(dǎo)致鋁板發(fā)脆的原因呢？
In recent years, the market demand for aluminum is more and more big, a lot of new aluminum manufacturers also appeared on the market, but because the technology does not pass, no production experience, the production of aluminum unqualified product quality, resulting in aluminum brittle, so what is the cause of brittle aluminum?
1、鋁板生產(chǎn)廠家對(duì)于因分流筋匯合不良造成的性能下降應(yīng)適當(dāng)增加筋與外表面、筋與筋匯流處的長(zhǎng)度，或者增大壓縮比來(lái)解決，模頭壓力的改變可以通過(guò)改變模頭平直段長(zhǎng)度來(lái)調(diào)整流料阻力。
1, aluminum manufacturers for shunt performance due to reinforcement caused by poor confluence decline should be appropriate to increase the rib and the outer surface, tendon and tendon at the confluence of the length, or increase the compression ratio, die pressure change can be adjusted by changing the flow resistance of the die head straight length.

2、定型模的冷卻速率，冷卻水溫往往沒有引起足夠的重視，冷卻水的作用是將型材拉伸的大分子鏈及時(shí)冷卻定型,達(dá)到使用目的。
2, the cooling rate of the mold and the cooling water temperature often fail to attract enough attention. The role of cooling water is to cool the profile chain in time and achieve the purpose.
3、口模截面設(shè)計(jì)不合理，尤其是內(nèi)筋的分布和交界面角度的處理，這樣會(huì)造成應(yīng)力集中現(xiàn)象存在，需要改進(jìn)設(shè)計(jì)和消除交界面處的直角和銳角。
3, the section design of the die is unreasonable, especially the treatment of the distribution of the inner reinforcement and the angle of the interface. This will cause the phenomenon of stress concentration. We need to improve the design and eliminate the right angle and sharp angle at the interface.
4、口模出料不均勻，造成型材壁厚薄不一致，或者密實(shí)度不一致，這也就造成了型材兩個(gè)面之間的力學(xué)性能上的差別。
4, the die material is uneven, resulting in inconsistent thickness of the profile wall, or inconsistency of density, which results in the difference in mechanical properties between the two surfaces.
5、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(zhǎng)度來(lái)決定的。模頭的壓縮比太小或平直段太短都會(huì)造成鋁板制品不致密，影響物理性能。
5, the pressure of the die head is insufficient and the pressure of the die head is directly determined by the compression ratio of the die, especially the length of the die flat section. The compression ratio of the die head is too small or the straight section is too short will cause the aluminum plate products to be not dense and affect the physical properties.
