除塵濾芯/粉末回收濾筒
一、風(fēng)速對過濾效率的影響
從事涂裝粉末回收濾芯以來，常遇到部分涂裝設(shè)備商反映：剛完工沒多久的粉末噴房排風(fēng)口處有比較明顯的透粉現(xiàn)象，或者是在噴房掛件處，粉末到處飛揚(yáng)；噴件工作區(qū)，塑粉回?fù)洚a(chǎn)生很明顯的溢粉現(xiàn)象。遇到這系列問題時，客戶經(jīng)常會習(xí)慣性的認(rèn)為產(chǎn)生透粉現(xiàn)象是由于濾布的孔徑太大了，塑粉跑出去了；產(chǎn)生溢粉現(xiàn)象是由于濾布的孔徑太小了，透風(fēng)量達(dá)不到。濾布的孔徑固然會對透粉溢粉產(chǎn)生一部分的影響，但濾芯過濾絕對不是簡單的粉篩篩粉原理，在設(shè)計制作粉末噴房時，設(shè)置合理的風(fēng)速是設(shè)備運(yùn)營好壞的關(guān)鍵。在設(shè)備運(yùn)行中，假如穿過濾布?xì)饬鞯娘L(fēng)速過大，會造成風(fēng)壓壓差加大，這時有一部分粉粒隨過大的風(fēng)壓氣流穿透濾布，被排放到風(fēng)管中，產(chǎn)生透粉現(xiàn)象。實踐數(shù)據(jù)表明，對于粉末回收濾芯，風(fēng)速增加一倍，粉末的透過率就增加一個數(shù)量級，過濾效率降低一個9；風(fēng)速減少一半，粉末的透過率會降低一個數(shù)量級，過濾效率增
二、粉末清理對濾芯過濾效率和濾芯壽命的影響
同一規(guī)格參數(shù)，同一濾材的濾芯，在不同的工作使用環(huán)境下，濾芯的過濾效率、產(chǎn)品壽命也存在很大的差別。濾芯在使用過程中，能否及時有效的清理濾布表面的積粉是影響濾芯過濾效率和產(chǎn)品壽命的關(guān)鍵所在。清理濾芯表面的積粉，目前涂裝設(shè)備上最常用的方法是脈沖反吹式，是壓縮空氣通過電磁閥瞬間從閥內(nèi)噴出，形成一股氣流作用于濾芯內(nèi)側(cè)，完成對濾芯表面的積粉清理。
影響清理效果的因素有4種：1、氣壓大小；2、氣體清潔度；3、濾芯材料；4、濾芯結(jié)構(gòu)。
1、氣壓太小是絕對震打不干凈濾芯表面的積粉的，在濾芯強(qiáng)度承受能力允許的情況下，震打氣壓越大越好，一般涂裝設(shè)備商都設(shè)置了5kg左右的氣壓，這主要考慮到市場上常規(guī)濾芯的承受能力有限，通宇濾芯經(jīng)過特殊材料制作的濾芯能夠承受（8~10）kg的氣壓，反吹時濾芯結(jié)構(gòu)不會變形脫蓋，濾布不會打裂撕破。
2、通過壓縮空氣進(jìn)入電磁閥的氣體也會影響反吹效果，假如氣體內(nèi)含有水分油污時，油水就會滲透到濾材內(nèi)部和塑粉粘結(jié)在一起，那時再大的氣壓也震打不了濾布表面的積粉，所以粉末噴房中的空氣壓縮機(jī)必須要配置相應(yīng)的過濾器進(jìn)行油水分離。
3、粉末回收濾芯本身的濾材質(zhì)量也會影響清粉效果，相比國內(nèi)濾材，進(jìn)口的優(yōu)質(zhì)濾材脫粉更容易；相比傳統(tǒng)聚酯纖維濾布，經(jīng)過表面處理的濾材清粉效果更加明顯突出，如基布表面做氟樹脂處理，濾芯就具備了防油防水防污的功能；在基布表面做聚四氟乙烯覆膜處理，濾芯就表現(xiàn)為表面過濾形態(tài)，塑粉不會進(jìn)入濾材內(nèi)部，脈沖反吹時粉末能整片脫落。
4、濾芯的外觀結(jié)構(gòu)也能直接影響到清粉效果。相對傳統(tǒng)圓筒式濾芯，錐形濾芯上大下小的形狀在脈沖震打時塑粉更容易脫落。底漏式的濾芯使震打下來的粉末直接滑落到粉房底部，小直徑淺折距的濾芯在脈沖震打時氣流更能使濾布向外膨脹，震落濾布表面的塑粉。
在使用粉末噴房過程中假如遇到塑粉清理不下來時，一定要分析找出原因，然后再解決問題。切記不要用棍子直接敲打濾芯表面，也不要用水清洗濾芯，因為用棍子敲打會造成濾布表面破損，濾芯內(nèi)支撐網(wǎng)彎曲收縮變形，會迅速造成濾芯報廢。用水清洗濾芯，鴻天濾業(yè)濾芯認(rèn)為這更是掩耳盜鈴的做法，水是能夠直接清洗到濾布表面的塑粉，但是藏在濾材纖維內(nèi)部的小顆粒粉塵一旦遇到水就會粘結(jié)成糊狀，粘附在濾材內(nèi)部的纖維間，這樣會造成空氣流量不夠濾芯阻力加大，嚴(yán)重縮短濾芯的使用壽命，原則上我們不建議客戶用水清洗濾芯。
