棋乐游1、GANGDUHEQIANGDUDI。BOLIGANGDEDANXINGMOLIANGBIMUCAIDALIANGBEI,DANBIGANG(E=2.1×106)XIAO10BEI,YINCIZAICHANPINJIEGOUZHONGCHANGGANDAOGANGXINGBUZU,RONGYIBIANXING;BOLIGANGZAISHUIZHONGTEBIESHIYANSHUIZHONGZHANGQISHIYONGSHI,YOUYUYANSHUIDESHENTOUYIJIBOLIGANGDERONGZHANGZUOYONG,BOLIGANGDEQIANGDUHUIMINGXIANSHUAIJIAN,BINGZUIZHONGDAOZHIPOHUAI。 1, stiffness and low intensity. The elastic modulus of fiberglass is twice as large as that of wood, but 10 times smaller than steel (E = 2.1 x106), so it is often not rigid in the product structure and easily deformed. FRP especially salt water in the water medium and long-term use, due to the effect of swelling of the salt water infiltration and glass reinforced plastics, glass fiber reinforced plastic obvious attenuation of the strength and eventually lead to destruction. 2、BOLIGANGGUANYEHUIFASHENG“FUSHI”,DANSHIYUPUTONGTANGANGDEFUSHIXIANXIANGBUTONGZHICHUZAIYUBOLIGANGGUANDE“FUSHI”SHITONGGUOCAILIAODEBIANZHIBIAOXIANCHULAIDE,BOLIGANGGUANZAIXISHUI、RONGZHANG、LAOHUAHOUFASHENGDEXINGNENGXIAJIANGJISHUYUBOLIGANGDEFUSHIFANCHOU,DUIYUBOLIGANGGUANERYAN,YOUYUXISHUIRONGZHANGSHENZHIBIHOUHAILVEYOUZENGJIA,DANSHIBOLIGANGGUANCAIZHIHEXINGNENGYIJINGFASHENGYANZHONGSHUAIJIAN,SHENZHIDADAOWUFASHIYONGDECHENGDU。 2, glass steel tube will occur, "corrosion", but is different from ordinary carbon steel corrosion phenomena in glass steel pipe "corrosion" is through the material of metamorphism, glass steel pipe in water absorption, swelling, aging occurs after the performance degradation of which belong to the category of corrosion of glass fiber reinforced plastic, for the glass tube, due to water absorption swelling even wall thickness increases slightly, but the glass steel pipe material and performance have been serious attenuation, even to the point of cannot be used. 3、BOLIGANGDEREPENGZHANGXISHUDA。BOLIGANGDEREPENGZHANGXISHUYUANGAOYUTANGANG(DAYUEGAOLIANGGESHULIANGJI),ZAIWENCHADADEDIQUCAIYONGZHANGJULIBOLIGANGGUAN,BIXUKAOLVWENCHAYINQIDEREZHANGLENGSUODUIBOLIGANGGUANDEPOHUAIZUOYONG。 3, the thermal expansion coefficient of fiberglass is large. The thermal expansion coefficient of glass fiber reinforced plastic is far higher than that of carbon steel (about two orders of magnitude), the temperature difference large area USES the long glass tube, heat bilges cold shrink caused by temperature difference must be considered on the destruction of the glass tube. 4、ZHANGQINAIWENXINGCHA。YIBANBOLIGANGBUNENGZAIGAOWENXIAZHANGQISHIYONG,TONGYONGJUZHIBOLIGANGZAI50℃YISHANGQIANGDUJIUMINGXIANXIAJIANG,TONGYONGXINGHUANYANGBOLIGANGZAI60℃YISHANG,QIANGDUYOUMINGXIANXIAJIANG。 4, long-term tolerance to temperature difference. General FRP can use for a long time at high temperature, general polyester FRP markedly reduced in intensity over 50 ℃, general-purpose epoxy FRP above 60 ℃, strength has significantly decreased. 5、LAOHUAXIANXIANG。LAOHUAXIANXIANGSHISULIAODEGONGTONGQUEXIAN,BOLIGANGYEBULIWAI,ZAIZIWAIXIAN、FENGSHAYUXUE、HUAXUEJIEZHI、JIXIEYINGLIDENGZUOYONGXIARONGYIDAOZHIXINGNENGXIAJIANG。 Aging. Aging is the common defects of plastic, glass fiber reinforced plastic is not exceptional also, in the ultraviolet, wind rain and snow yarn, chemical media, such as mechanical stress under the action of easily lead to performance degradation. 6、CENGJIANJIANQIEQIANGDUDI。CENGJIANJIANQIEQIANGDUSHIKAOSHUZHILAICHENGDANDE,SUOYIHENDI。 Low shear strength between layers. The shear strength between layers is based on resin, so it's low. 7、SHIGONGZHILIANG。CAIYONGBOLIGANGGUANDELINGYIGEGUANJIANWENTIJIUSHIXIANCHANGJIEKOUDECHULIFANGMIAN,MUQIANWOGUOBOLIGANGSHIGONGXIANGMUZHONG,JIEKOUZHILIANGWENTIHENTUCHU,YOUQIDUIYUZHANGJULIGUANDAO,JIEKOUSHULIANGHENDUO,JIEKOUCHULIDEHAOHUAIZHIJIEYINGXIANGZHEZHENGGEGONGCHENGDEZHILIANG。 Construction quality. Using glass steel tube another key problem is the site of the interface processing, at present our country FRP construction projects, the interface quality problem is very outstanding, especially for long distance pipeline, interface quantity many, the stand or fall of interface processing quality directly influences the whole engineering.
