boracic adj.= boric.

boracic ointment

The boracic acid was used to prepare flexible graphite and the effect of amount of boracic acid addition on expanded volume , oxidation resistance , specific resistance and tensile strength of the fexible graphite obtained were analysed 摘要初步探討了制造柔性石墨材料過程中加入添加劑硼酸的方法,并就硼酸的加入量對其膨脹倍數、抗氧化性、電阻率、抗拉強度等的影響進行了比較和分析。

In order to prepare low dielectric constant glass powder , we use sio2 , boracic acid etc as raw material to prepare glass powder . the result of testing is : its dielectric constant is about 4 . 0 , and it is suit for our experiment 作為低介常數的玻璃粉料,采用sio2 、硼酸等為原料,通過熔融、研磨制得了玻璃粉料,其介電常數約為4 . 0 ,介質損耗為10 10 4 。

The results showed that the addition of boracic acid can increase the oxidation resistance and tensile strength of the flexible graphite , however , it has few effect on the other properties of the flexible graphite 實驗表明,添加劑硼酸使柔性石墨材料在抗氧化性方面具有明顯的優越性,抗拉強度有所增加,而對其它性能的影響不大。

Qinghai ridge boron & lithium co . , ltd , certificited in 2000 , is a aggregate resource corporation of mining boron mine , producing boracic acid , boride re - processing and selling industrial used salt 青海中天硼鋰礦業有限公司成立于2000年,是集硼礦開采、硼酸生產、硼化物深加工、工業用鹽生產銷售的資源性企業。

Boracic modified penolic resin with boracic acid and hydroxymethyl phenol was manufactured after hydroxymethyl phenol was created with in a special way 摘要通過在一定條件下,先將苯酚、甲醛制成羥甲基酚,然后改變條件與硼酸共聚,制得具有合成穩定和較好耐熱性的硼改性酚醛共聚樹脂。

The influences which caused by the kinds of the catalyzer , phenol and formaldehyde proportion , boracic acid addition and etc were discussed 探討催化劑種類、酚醛比、硼酸加入量等對其性能的影響。
