Sponge roller
Sponge roller are made of PVA,PP,PU or other material, normally used for water absorb.
PVA sponge roller have strong water absorb feature, but it can not resist acid and alkali,it normally used on PCB brushing machine and glass making or other field.
PP sponge roller have less water absorb function than PVA sponge roller,but it can resist acid and alkali,it normally used on electroplating field.
PU sponge roller also have less water absorb function, but it can resist strong acid and alkali,normally used on PCB field.

The first domestic special trailer for sanitation developed by the special vehicle company of the CNHTC Special Purpose Vehicles Co., Ltd. (Qingzuan) has been successfully rolled out and delivered to users of the Beijing Cleaning Group.
Earlier this year, the special-vehicle business unit of the CNHTC Special Purpose Vehicle Company was informed that Beijing Clean Group needed to purchase a special trailer for sanitation purposes for the transit transport of domestic garbage in Beijing. Before that, Beijing Cleaning Group had been relying on Germany to import such models. Due to certain factors, it is no longer continuing to import from abroad. The Beijing Cleaning Group has sought out a number of special-purpose vehicle manufacturers in China. After a comparison, the user finally selected the special vehicle company for the research and development and manufacturing of the heavy-duty trucks that have the qualifications and conditions for producing such models.
This kind of special trailer for sanitation is different from the common trailer that transports goods on the road. It has some special features: one is to have a special platform with a wheeled bin, and the other is to have a bin locking mechanism. The performance index of the vehicle must comply with European standards.
In order to meet the needs of users and ensure vehicle performance requirements, the Qingzhou Special Vehicle Business Unit strictly controls the production and processing of parts and components, and the selection and purchase of purchased parts. In the production and installation phase, we strive for excellence to ensure quality. The tow bar, turntable, brake system and electrical system of the car have reached the European standard. Among them, the brake system adopts the world-advanced EBS system, which can make the vehicle anti-locking, anti-skid and anti-rollover functions. The earth improves the safety of the vehicle; the electrical system adopts German standard trailer-specific wiring harnesses and connectors, which are waterproof, anti-shedding, and easy to install; the lamps are also the latest products from Europe, and the small arms protruding from the body are made of high-quality rubber. Material, good softness, anti-collision. In order to ensure the overall appearance of the car body, the car was electroplated in its entirety. In order to solve the problem of huge body, complicated structure and difficult plating, it was only after a series of visits to a number of electroplating factories to finally select the manufacturers with excellent quality, thus ensuring the quality of plating and gaining the users' approval and praise.
