鋁板發(fā)脆與哪些特性有關(guān)系

1、對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)計階段可選擇不同的壓縮比來改變擠出壓力,但必須注意機(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。
1, the performance is due to shunt reinforcement caused by poor convergence 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 section length; in the mold design stage can choose different compression ratio the change of extrusion pressure, but must pay attention to and head compression ratio of extruder screw compression ratio to adapt; also by changing the formula, adjusting the extrusion process parameters, increase the porous plate to change the size of the melt pressure.
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)計不合理,尤其是內(nèi)筋的分布和交界面角度的處理,這樣會造成應(yīng)力集中現(xiàn)象存在,需要改進(jìn)設(shè)計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面之間的力學(xué)性能上的差別,至于壁薄等非標(biāo)型材這里就不再多說。
4, the die material is not uniform, resulting in the uneven thickness of the wall, or the inconsistency of the density. This also causes the difference between the mechanical properties between the two surfaces of the profile. As for the non - standard sections, such as wall thin, there is no more to be said.
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度來決定的。模頭的壓縮比太小或平直段太短都會造成制品不致密,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 products to be not dense and affect the physical properties.
