玻璃鋼停車(chē)護(hù)欄桿

玻璃鋼桿應(yīng)用于停車(chē)桿的優(yōu)勢(shì)
　 適用范圍：小區(qū)道閘、收費(fèi)站道閘、停車(chē)場(chǎng)道閘、危險(xiǎn)或限制路段道閘等。
質(zhì)量輕：玻璃鋼桿的密度為1.9g/cm³,約為鋼質(zhì)停車(chē)桿的三分之一（鋼抽油桿的密度為7.85 g/cm³），可以大大降低道閘閘機(jī)懸點(diǎn)載荷，因此可以運(yùn)用功率小的電動(dòng)機(jī)、較小的變速箱、較小的平衡塊、較輕便的結(jié)構(gòu)形式，從而達(dá)到節(jié)約電能、提高綜合效率的目的。
　　彈性好：玻璃鋼桿的彈性模量為（4.0-6.0）×10⁴MPa,僅為鋼質(zhì)道閘桿的四分之一左右（鋼質(zhì)道閘桿的彈性模量為2.1×10⁵MPa），這樣可以延長(zhǎng)閘機(jī)的使用壽命，還可以增加閘機(jī)的有效沖程，增加有效開(kāi)合次數(shù)。
　　抗腐蝕能力強(qiáng)：玻璃鋼桿具有良好的抗腐蝕性、耐疲勞特性；主要由無(wú)堿、無(wú)捻玻璃纖維與熱固性樹(shù)脂預(yù)熱固化而成，是電的非導(dǎo)體，在鹽水及含有二氧化碳、硫化氫等環(huán)境下實(shí)驗(yàn)，無(wú)腐蝕現(xiàn)象。這樣可以減少因腐蝕造成閘機(jī)桿斷裂而停止作業(yè)的情況，達(dá)到減少作業(yè)成本和增產(chǎn)創(chuàng)效的目的。
強(qiáng)度高：玻璃鋼桿的抗拉強(qiáng)度為810MPa，達(dá)到了D級(jí)鋼桿的抗拉強(qiáng)度，短期最大應(yīng)力可達(dá)300MPa，最大載荷可達(dá)15t。
環(huán)保：傳統(tǒng)的停車(chē)桿多數(shù)采用鋁質(zhì)桿，而鋁質(zhì)桿在生產(chǎn)制造中需要做氧化等處理，會(huì)對(duì)環(huán)境造成惡劣影響。使用玻璃鋼桿替代鋁質(zhì)桿，可充分降低制造過(guò)程中對(duì)環(huán)境的影響。

The Advantages that FRP be Used in Parking Rod
Applications: residential road gate, toll gate, parking brake, dangerous or restricted road gate, etc.
Light weight: FRP rods density is 1.9g/cm³, about 1/3 of the parking rod steel (steel sucker rod density is 7.85 g/cm³), can greatly reduce the gate suspended load, so you can use small power motors, smaller gearbox, smaller balance blocks, lighter structure. In order to save energy, improve the comprehensive efficiency of the.
Good flexibility: the elastic modulus of FRP rods for (4.0-6.0) * 104MPa, only about 1/4 of the steel gate rod (elastic modulus of steel gate rod is 2.1 * 105MPa), it can prolong the service life of the gate, but also can increase the effective stroke of the gate, increase the effective opening and closing times.
Strong corrosion resistance: glass steel has corrosion resistance and good fatigue properties; It is mainly preheated and cured by thermosetting resin and glass fiber without alkali and twisting. It is a non conductor of electricity. It is tested no corrosion under the environment of brine and containing carbon dioxide and hydrogen sulfide. This can reduce the situation of stopping operation due to corrosion causing brake rod breakage, so as to reduce operation cost and increase production efficiency.
High strength: tensile strength of FRP rods for 810MPa, reached the tensile strength of D steel, the biggest short-term stress of 300MPa, the maximum load of up to 15t.
Environmental protection: most of the traditional parking rods are made of aluminum rods, while aluminum rods need to be oxidized in production, which will cause adverse effects on the environment. The use of fiberglass rods instead of aluminum rods can reduce the environmental impact in the manufacturing process.
