Anonymous users2024-01-24According to the sofa leather standard, it is impossible for the leather to lose the paint (where does the paint come from?). It is impossible to peel off (how to take off the skin, the skin of a person peels off the epidermis, and the dermis is processed from the animal skin that has been removed from the epidermis).
The quality requirements of furniture leather are divided into two parts: sensory requirements and physical and chemical properties. (1) Sensory requirements.
The texture is fine and uniform, and the color is uniform, no flowers, and no cracks. The coated leather is evenly finished, the coating is firmly adhered to, and the slurry is not dropped or cracked. The thickness of the whole sheet is basically uniform, and the leather body is plump, soft, elastic, and has no peculiar smell. The leather is clean and non-greasy.
2) Physical and chemical properties.
There are seven physical and chemical performance indicators:
1) Tensile strength; It is divided into two types according to thickness. mm2, type 1 10N mm2, type 2 15 N mm2.
2) Tear strength: It is divided into two types according to thickness. Type 1 is 30N mm, Type 2 is 35N mm. 3) Elongation at break 80.
4) Color rubbing fastness: dry rub grade, wet rub grade.
5) Coating adhesion fastness N 10 mm. 6) pH 3-5. 7) PH dilution difference <.
Tear strength, color rub fastness, coating adhesion fastness is the main control index, if one of the three is unqualified, the furniture leather is unqualified.
