PE管主要運(yùn)用在排水、輸送、排污等行業(yè)，而PE管需要通過(guò)熱熔焊機(jī)、對(duì)接機(jī)進(jìn)行連接，杭州先創(chuàng)熱熔設(shè)備廠主營(yíng)全自動(dòng)熱熔對(duì)接焊機(jī)、全自動(dòng)熱熔焊機(jī)設(shè)備，焊接優(yōu)先域有著超高的工藝。
在進(jìn)行PE熱熔焊接是，要注意溫度控制要正確。PP-R熱熔焊接溫度為：253℃-274℃。如果溫度低于253℃，管子和管件僅僅是薄薄的表面一層的熔化，一旦它們之間進(jìn)行熔接，其熔接的強(qiáng)度就得不到保證，這就是我們通常所說(shuō)的假焊現(xiàn)象；反之，如果溫度高于274℃，管子和管件的表面分子遭到高溫的破壞，使得PP-R形成稀薄的液體，連接后會(huì)使管子內(nèi)徑變小，更重要的是，連接部分會(huì)發(fā)生脆裂，尤其是在管路系統(tǒng)全部完工后進(jìn)行通水加壓，經(jīng)常會(huì)發(fā)生此類問題。
而且恒溫時(shí)間要長(zhǎng)。恒溫時(shí)間的長(zhǎng)短是熱熔焊接設(shè)備性能好壞的重要標(biāo)志之一。熱熔設(shè)備在升溫至設(shè)定溫度后仍有一個(gè)熱量消耗的問題，特別是在冬季，風(fēng)口處，即便是在非作業(yè)間隙，其熱耗也是很大的，而一旦作業(yè)時(shí)，其管子和管件都在分別消耗熱能，這就要求設(shè)備有很強(qiáng)的熱能儲(chǔ)存能力和及時(shí)補(bǔ)充能力。
PE pipe is mainly used in drainage, transportation, sewage and other industries, and PE pipe needs to be connected by hot melt welding machine, butt machine, Hangzhou first create hot melt equipment factory main automatic hot melt butt welding machine, automatic hot melt welding machine equipment, welding priority domain has super high technology.
PE hot melt welding is to pay attention to the correct temperature control. Pp-r hot melt welding temperature: 253℃-274℃. If the temperature is lower than 253℃, the pipe and pipe fittings are only a thin surface layer of melting, once they are welded, the strength of the welding can not be guaranteed, this is what we usually call false welding phenomenon; On the contrary, if the temperature is higher than 274℃, the surface molecules of the pipe and pipe fittings are damaged by high temperature, resulting in the formation of thin liquid PP-R, which will make the pipe diameter smaller after the connection. More importantly, the connection part will be brittle, especially after the completion of the pipeline system water pressure, this kind of problem often occurs.
And keep it constant for a long time. The length of constant temperature time is one of the important indicators of the performance of hot melt welding equipment. Hot melt equipment after heat setting temperature will still be a question of heat consumption, especially in the winter, FengKouChu, even in the working clearance, its heat loss is very big, once operations, the pipe and pipe fittings in the consumption of thermal energy, respectively, which requires the equipment has a strong heat storage capacity and the ability to replenish.
