一看用料.優(yōu)質(zhì)的鋁合金門(mén)窗設(shè)備所用的鋁型材,厚度、強(qiáng)度和氧化膜等,應(yīng)符合有關(guān)的國(guó)家標(biāo)準(zhǔn)規(guī)定,壁厚應(yīng)在1.2毫米以上,抗拉強(qiáng)度達(dá)到每平方米毫米157牛頓,屈服強(qiáng)度要達(dá)到每平方毫米108牛頓,氧化膜厚度應(yīng)達(dá)到10微米.如果達(dá)不到以上標(biāo)準(zhǔn),就是劣質(zhì)鋁合金門(mén)窗設(shè)備,不可使用.
A look at the material. Aluminum Alloy used aluminum doors and windows equipment quality, thickness, strength and oxide film, shall conform to the relevant provisions of the national standard, the wall thickness should be more than 1.2 mm, the tensile strength of 157 mm per square metre of Newton, yield strength to reach 108 per square millimeter of Newton, the thickness of the oxide film should reach 10 micron. If not up to the above standard, it is inferior Aluminum Alloy doors and windows equipment, can not be used.

二看加工.優(yōu)質(zhì)的斷橋鋁門(mén)窗設(shè)備,加工精細(xì),安裝講究,密封性能好,開(kāi)關(guān)自如.劣質(zhì)的鋁合金門(mén)窗設(shè)備,盲目選用鋁型材系列和規(guī)格,加工粗制濫造,以鋸切割代替銑加工,不按要求進(jìn)行安裝,密封性能差,開(kāi)關(guān)不自如,不僅漏風(fēng)漏雨和出現(xiàn)玻璃炸裂現(xiàn)象,而且遇到強(qiáng)風(fēng)和外力,容易將推拉部分或玻璃刮落或碰落,毀物傷人.

Two see. The aluminum doors and windows processing equipment, high precision machining, installation stress, good sealing performance, switching freely. Aluminum Alloy inferior door window equipment, choose aluminous profile series and specifications, processing by saw cutting instead of crudely made, milling, no installation required, poor sealing performance, the switch does not freely, not only air leaks and glass burst phenomenon, and encountered strong winds and force, easy to push and pull part or glass fall or drop, and destroy wounding.
三看價(jià)格.在一般情況下,優(yōu)質(zhì)斷橋鋁門(mén)窗設(shè)備備因生產(chǎn)成本高,價(jià)格比劣質(zhì)鋁合金門(mén)窗設(shè)備要高30%左右.有些有壁厚僅0.6-0.8毫米鋁型材制作的鋁合金門(mén)窗設(shè)備,抗拉強(qiáng)度和屈服強(qiáng)度大大低于國(guó)家有關(guān)標(biāo)準(zhǔn)規(guī)定,使用很不安全.
Three see price. In general, high quality aluminum doors and windows equipment because of its high production cost, the price ratio of Aluminum Alloy inferior door window equipment is 30% higher. Some have only 0.6-0.8 mm aluminum production equipment Aluminum Alloy window wall thickness, tensile strength and yield strength is much lower than the relevant national standard, it is not safe to use.
此外,目前加工鋁合金門(mén)窗設(shè)備的個(gè)體戶較多,他們不懂得鋁合金門(mén)窗設(shè)備的結(jié)構(gòu)特點(diǎn)及其性能.為了降低成本偷工減料,以次充好,產(chǎn)品的隱患較大,一般不宜采用.選用正規(guī)鋁合金門(mén)窗設(shè)備生產(chǎn)廠家的產(chǎn)品. 這里要特別說(shuō)明一點(diǎn):現(xiàn)在的國(guó)家標(biāo)準(zhǔn)的型材厚度為1.4mm,如果供應(yīng)商選擇的是1.2mm或者1.0mm壁厚甚至更薄的材料的話,都是屬于不達(dá)標(biāo)的產(chǎn)品,請(qǐng)大家在選購(gòu)時(shí)注意.
In addition, the current processing equipment more Aluminum Alloy doors and windows of the self-employed, they do not understand the structure characteristics and performance Aluminum Alloy doors and windows equipment. In order to reduce the cost of shoddy work, shoddy, the hidden trouble of the product is large, the general should not be used. It is best to choose the regular Aluminum Alloy doors and windows equipment manufacturers products. It must be clear: the thickness of the profile now the national standard is 1.4mm, if the supplier selection is 1.2mm or 1.0mm thickness even thinner material, are substandard products, please pay attention at the time of purchase.
