GB15256-2014塑料低溫脆化試驗(yàn)機(jī)檢查電線之塑料外殼以及硫化橡膠在低溫測(cè)試時(shí)的脆化特性。

The embrittlement of plastic case of the wire and the embrittlement of vulcanized rubber during low temperature test.

用戶可以選擇TS-BC直線性沖擊試驗(yàn)方法或者TS-BT擺錘型沖擊試驗(yàn)方法以滿足客戶對(duì)設(shè)備的不同需求。

The user can choose the TS-BC linear impact test method or TS-BT pendulum type impact test method to meet the customer's different needs of the equipment.

試驗(yàn)時(shí)將試樣固定于夾具上，然后將試樣浸泡坐在低溫介質(zhì)中5分鐘，用2±0.2m/s的線速度沖擊試樣，zui后檢查試樣在zui低溫度是否出現(xiàn)裂紋、裂縫、小孔、以及是否完分離成碎片。

Test sample is fixed on the fixture, then soaked samples sitting in low temperature medium in 5 minutes, with 2 + 0.2 M / s line speed impact test specimens, the final inspection sample in the lowest temperature whether cracks, cracks, holes, and whether separates into pieces.

GB15256-2014塑料低溫脆化試驗(yàn)機(jī)通過(guò)轉(zhuǎn)換卡盤(pán)托架底座可以連續(xù)的進(jìn)行樣品測(cè)試，可以節(jié)省樣品放回原處時(shí)間，滿足很多樣品各自的測(cè)試標(biāo)準(zhǔn)。

Through the conversion of the chuck bracket base can be continuous sample test, can save the sample back in place of time, meet a lot of samples of the respective test standard.

塑料低溫脆化試驗(yàn)機(jī)制冷方式 The refrigeration mode of multifunctional plastic cryogenic embrittlement test machine
采用二段式壓縮機(jī)快速降溫制冷，zui低溫度可達(dá)-76℃(如需低于-76℃，可定制)。

Two stage compressor cooling refrigeration, the lowest temperature of up to -76 (for example, can be customized for less than -76).

溫度可控性高，低溫槽中液體傳熱介質(zhì)可啟用攪拌馬達(dá)，使溫度均勻性更佳。毎次可測(cè)試4組試樣， 旋轉(zhuǎn)定位夾具對(duì)每組試樣進(jìn)行沖擊測(cè)試，檢査出現(xiàn)脆性破壞的zui低溫度。

The temperature can be controlled and the heat transfer medium of the liquid in the cryogenic tank can be used for stirring the motor, and the temperature uniformity is better.. Each time 4 groups of samples testing, rotary positioning fixture for each specimen of impact test and laboratory examination appear brittle failure of minimum temperature.
