进口纯天然环保涂料2-威尼斯泥Grasello 600

本人用此材料作过多种产品,包括:威尼斯泥平刮效果,威尼斯泥+金效果,仿石材效果,太阳金属,平面金属,海绵金属,金属砂岩,立体砂岩等。对这种材料,有几点本人是认可和向大家推荐的。一是其光洁度,非常细腻与光洁,表干后用铲刀抛几下就光亮如镜,威尼斯石膏则不会有这种效能;二是其环保度,未添加任何化学成分,是最环保的纯天然涂料;三是其适用范围较大,墙面、天花均可,客厅卧室厨房卫生间均能适用;四是其可作出多种效果,而马来则不然;五是其成本相对较低,造价不会太高。一般中、高档装修都能接受其价位。

现将其英文介绍附于后,有兴趣者可进一步了解



Grassello 600



Over the years, the grassello di calce has been extremely important in coating old historic buildings, improving their appearance and creating an effective protective layer for the plaster and brickwork.

The Colorificio Veneziano has perfected a product that maintains the features of the old lime coating, updated to the modem needs of building work.

The grassello di calce undergoes very long seasoning, by baking carefully selected calcareous stones. For the stone to become an aerial bond in the paste, it must first be baked in special ovens and then turned off.

Baking lasts around 20 hours at 900°C, during this process, which is called decarbonation, the stones give off the water and carbon dioxide they contain.

Decarbonation transforms the stone from calcium carbonate into calcium oxide, i.e. burnt lime.

The burnt lime that is formed Is turned off by immersing it in fresh water: this process is called hydration and causes an exothermic reaction, i.e. a great deal of heat is developed. This is when it transforms from calcium oxide to calcium hydrate.

The reaction is very long to allow the formation of crystals with the required binding properties.

The drying time for GRASSELLO 600 varies depending on the relative humidity in the air, and during this time it must be worked with a spatula to create the smooth glossy surface.

The natural hardening process for GRASSELLO 600 is called carbonation, which involves slowly absorbing the carbon dioxide from the air.

This absorption of carbon dioxide transforms it from calcium hydrate to calcium carbonate, which is the material the original stone was formed of.

This is why we consider GRASSELLO 600 a totally natural material, because its production cycle is a totally closed cycle.

For these natural merits GRASSELLO 600 has met with great approval in bio building.
