Product Description

PU leather machine LZ828B

The solvent pollution problems exist in the solvent-based polyurethane synthetic leather production were reviewed. The main way for the clean production of polyurethane synthetic leather was put foword.The formation mechanism and key technology of the solvent-free polyurethane synithetic wre discussed.

A.B Raw materials are conveyed to injection head on the rack truck’s by the filter metering pump, the injection head moves back and forth on the patterned paper at a constant speed , scraper on the assembly line’s scrapes the materials into film, and then heating the film into foam, which will be laminated with the base material( Split Bonded Leather, Substrate leather or Other Material) when the PU foam present a stringy state , the compression roller grinds them into a synthetic, at last, the PU leather will be separated on the assembly line after heating and shaping in drying oven.

1	Production capacity	30000square foot/day

3	Injection pressure	0.1~3.99mpa
4	Mixing rate	50-100:100
5	Consistency(22)	Poly/ISO:500~2000mpas
6	Injection method	continous
7	Injection accuracy	0.001
8	Pneumatic working pressure	0.6~0.8mpa
9	Volume of tank	200L
10	Working width	1600/1900/2200mm
11	Total power	95KW 107KW 115KW

Advantages

	Traditional Solvent	Solvent free
1	30% solid content ; 70% Solvent (DMF)	100% solid content,without solvent
2	Serious pollution(DMF)	non emission,non pollution
3	High energy consumption(require high temperature to volatilize the DMF)	Low energy consumption,the dry oven without air exhaust system,without volatiles.
4	Low production efficiency: the leather producing need several procedures: producing base layer(wet process layer) first,and then plying-up the base surface layer on dry process production line with binder	Finishing the whole procedure on the dry process production line without glue directly.(Scraping surface course first,and then scraping the foam layer,connecting them together when the leather in cure period with any binder
5	Weak elastic,easy defomation	Strong elastic,not easy to deformation
6	Finished products with residual DMF	Not contain harmful substance

Application

Environmental solvent-free leather production technology mainly refers to have the surface blade coated through or nonwovens ,and solid content of blade coating foaming layer would be 100% after drying,the two-component PU materials directly stick to raw materials like aplit leather base cloth to produce composite leather which is widely use in shoes ,garment,sofa,bags, suitcase,belt and other field.
