甘肅塑料桶注塑,太脆了,我怎么辦?

塑料桶脆,怎么辦?


有朋友問,塑料桶用412MK49注塑的,但太脆,怎么辦?


怎么辦呀,聽我說。412MK49材料是沙伯基礎公司的高韌性PP料。高韌性,懂嗎,不可能脆。




既然現在脆了,我只能說你去化驗下材料。衡量脆性的指標通常3個:拉伸模量,彎曲模量,斷裂伸長率。我們查到的這種料的彎曲模量是800MPA,斷裂伸長率是500%,韌性的指標都這樣了,怎么可能脆,你去化驗下,看指標是否對的上吧。




塑料桶的價值不高,檢測幾乎沒有,所以市場上這種產品的材料的核心要素不是韌性好而是便宜,便宜的料怎么配?我就不說多了,怕得罪人,他的配方方向與韌性的方向不同的。


最后既然料是這樣了,怎么辦呢?加增韌劑吧。




PP的增韌劑常見的有 POE , EPDM ,買來混用,至于比例嘛。。。。呵呵, 10%不行就 20% ,還不行就 30% ,終歸可以的。




但加了增韌劑后上述指標,彎曲模量 / 拉伸模量會下降,斷裂伸長率 上升,同時拉伸強度降低,沖擊強度增加,等等,指標一片片的變化,所以你要想好。
