保溫鋁卷生產(chǎn)廠家家會(huì)在壓型加工過(guò)程中注意設(shè)備的間距,不能因?yàn)殚g距過(guò)小導(dǎo)致壓型過(guò)程中出現(xiàn)開(kāi)裂現(xiàn)象,同時(shí)要注意清理設(shè)備上面的污油、灰塵以及金屬顆粒,保證壓型加工后保溫鋁卷的表面光潔度,防止表面劃傷。

Insulation aluminum coil manufacturers will pay attention to the equipment in the distance compression process, not because the spacing is too small causing cracking phenomenon of pressing process, and we should pay attention to the above cleaning equipment, waste oil, dust and metal particles, pressure to ensure machining after insulation surface finish of the aluminum coil, prevent scratches on the surface.

保溫鋁卷可以通過(guò)壓型技術(shù)制作各種花紋,保溫鋁卷廠家使用壓型設(shè)備將其壓制成各種型號(hào)的壓型鋁板或者瓦楞鋁板,可以分為光鋁卷壓型以及彩涂鋁卷壓型,產(chǎn)品被廣泛應(yīng)用在設(shè)備保溫,屋面以及墻面方面。有人會(huì)問(wèn)如果鋁卷直接進(jìn)行壓型的話,不會(huì)開(kāi)裂嗎?

Insulation aluminum coil by pressure type technology to produce various patterns, thermal insulation aluminum coil manufacturers use pressure equipment be pressed into various types of pressure type aluminum or corrugated aluminum, aluminum coil can be divided into light pressure type and color coated aluminum roll type, products are widely used in insulation equipment, roof and metope. Some people ask, if the aluminum coil directly press type, will not crack it?

其實(shí)保溫鋁卷廠家會(huì)采用經(jīng)過(guò)軟化處理的H24狀態(tài)才能保證壓型不開(kāi)裂。保溫鋁卷的壓型類似于折彎,經(jīng)過(guò)壓型以后強(qiáng)度增加,可以在建筑屋面使用,也成為屋面保溫鋁板。

In fact, the insulation aluminum coil manufacturers will use the softening treatment of H24 state to ensure that the pressure type is not cracking. The shape of the insulated aluminum coil is similar to the bending, and it can be used in the roof of the building, and also become the roof insulation aluminum plate after the strength increased after pressing.
