西安太阳能光伏结构胶（太阳能光伏组件密封胶）

光伏行业，太阳能电池板装框用的硅胶，固化时候有味道，请问有毒吗？担心对呼吸道和肺不好！~

硅胶本身是没有毒的 但是固化的时候气味很难闻 这个我有亲身体会 既然不好受 我一般选择远离 没事的时候不靠近总是对的 不过觉得长期从事这个不好 还是不放心可去医院检查下

太阳能光伏板采用玻璃胶粘接性价比高吗

看板子是硬板还是柔性板  如果是硬板的话建议螺丝固定 如果是柔性板的话 可以粘贴的。还有就是看你安装在什么位置。

太阳能光伏组件密封胶的UL认证中，阻燃性一般都是做到V-0级，更高的不是5VA级吗？5VA级的测试我们能做吗？

塑料的防火认证更高级是5VA,申请5VA周期很长，费用很高，如果材料不行还过不了。

根据UL94标准判定材料的难燃性水平。按照HB、V-2、V-1、V-0的顺序，难燃性依次增大。一般说的难燃材料指的是V-0。除了传统的评价 *** 之外，还设定了上一级的5V评价。作为定位，难燃性顺序依次为V-0、5VB、5VA。由于5V评价的 试验 *** 与传统相比有些不同，所以卡中象"V-0、5VA"那样就表示进行了两个 试验 。难燃性 HB V-2 V-1 V-0 5VB 5VA

Specimens

Bars: Length 125 mm (5 in) x Width 13 mm (0.5 in) x Thickness [typically 3.0 mm (1/8 in)].

Plaques: Length 150 mm (6 in) x 150 mm (6 in) x Thickness [typically 3.0 mm (1/8 in)].

Procedure for Bars

1.A total of 10 specimens (2 sets) are tested per thickness.

2.Five specimens of each thickness are tested after conditioning for 48 hours at 23 degrees C and 50% RH.

3.Five specimens of each thickness are tested after conditioning for 7 days at 70 degrees C.

4.For bar specimens, the specimens are mounted with the long axis vertical.

5.A 125 mm overall high Bunsen burner flame with a 40 mm blue inner cone is applied to the lower corner of each specimen at an angle of 20 degrees from vertical such that the tip of the blue inner cone touches the specimen. The flame is applied for 5 seconds and removed for 5 seconds. The operation is to be repeated until each specimen has been subjected to 5 applications of the test flame.

Procedure for Plaques

Same as for bars except that the plaques are to be mounted on the horizontal plane with the flame applied to the center of the bottom surface of the plaque.

Requirements for 5VA

1.The specimens may not burn with flaming or glowing combustion for more than 60 seconds after the fifth application of the test flame.

2.The specimens may not drip flaming particles that ignite the dry absorbent surgical cotton located 300 mm below the test specimen.

3.Plaque specimens may not exhibit burnthrough.

Requirements for 5VB

1.The specimens may not burn with flaming or glowing combustion for more than 60 seconds after the fifth application of the test flame.

2.The specimens may not drip flaming particles that ignite the dry absorbent surgical cotton located 300 mm below the test specimen.

3.Plaque specimens can exhibit burnthrough.

太阳能光伏接线盒灌胶的好还是非灌胶的好？哪种更防水防晒耐用一点呀?

灌胶的话，体积更小，所以成本也会低一点，而且它散热面积要大一点，但是后期安装的时候还要再灌胶，对组建方来说，比较麻烦。而非灌的话是通过空气散热的，相对来说散热性能稍微差一点，但它的安装程序简化了，用起来更方便。总之，这2种各有各的优缺点，具体就要看你自己怎么选择了。近年来在江浙一带做这一块的，弗沙朗、人和、佳明和康迪这几家都是挺不错的，2种类型的接线盒他们也都有生产，你可以再具体了解了解。
