| | 涂裝生產(chǎn)線前處理設(shè)備 涂裝生產(chǎn)線前處理設(shè)備是表面處理常用的設(shè)備，為涂裝前對(duì)工件表面之氧化皮、鐵銹、油脂、塵土等污垢物進(jìn)行清洗的工序，使涂裝粉體與金屬表面結(jié)合牢固、附著力強(qiáng)、從而使產(chǎn)品獲得更高的品質(zhì)，延長(zhǎng)產(chǎn)品的使用壽命。 前處理分為噴霧式、浸液式、潛泳式或結(jié)合式處理，可視工件及具體生產(chǎn)要求選擇處理方式。一套完整的前處理生產(chǎn)線設(shè)備由槽體、噴淋系統(tǒng)、加熱控溫系統(tǒng)、通風(fēng)系統(tǒng)、磷化液沉淀除渣系統(tǒng)、噴淋室體和照明裝置組成。該生產(chǎn)線可實(shí)現(xiàn)全自動(dòng)控制。 前處理設(shè)備一般多采用噴淋式多工位前處理機(jī)組形式，其原理是利用機(jī)械沖刷加速化學(xué)反應(yīng)來(lái)完成除油、磷化、水洗等工藝過(guò)程。 鋼件噴淋式前處理的典型工藝是：預(yù)脫脂、脫脂、水洗、水洗、表調(diào)、磷化、水洗、水洗、純水洗。 前處理還可采用拋丸清理機(jī)，適用于結(jié)構(gòu)簡(jiǎn)單、銹蝕嚴(yán)重、無(wú)油或少油的鋼件，其優(yōu)點(diǎn)是無(wú)水質(zhì)污染。 。 |
Pretreatment equipment of coating production line
The pretreatment equipment of the coating production line is a common equipment for surface treatment. It is a process to thoroughly clean the scale, rust, grease, dust and other dirt on the workpiece surface before coating, so that the coating powder can be firmly combined with the metal surface with strong adhesion, so that the product can obtain higher quality and prolong the service life of the product.
Pretreatment can be divided into spray type, immersion type, submerged type or combined type. The treatment method can be selected according to the workpiece and specific production requirements. A complete set of pretreatment production line equipment consists of tank body, spray system, heating and temperature control system, ventilation system, phosphating solution sedimentation and slag removal system, spray chamber body and lighting device. The production line can realize full automatic control.
Pre treatment equipment generally adopts spray type multi station pre-treatment unit. Its principle is to use mechanical scouring to accelerate chemical reaction to complete the process of oil removal, phosphating, water washing and so on.
Typical spray pretreatment processes for steel parts are pre degreasing, degreasing, water washing, water washing, surface conditioning, phosphating, water washing, water washing and pure water washing.
The pre-treatment can also adopt shot blasting machine, which is suitable for steel parts with simple structure, serious corrosion, no oil or little oil. Its advantage is no water pollution.
