Why is PU material environmentally friendly (isn’t PU stone skin a stone?)
Material collision has always been pursued by designers
A visual sensory impact effect
In the past two years, concave and convex stone finishes
Appears in many desktop classic cases
But some people respect it and stay away
After all, factors such as raw materials, cost,
Problems such as transportation and construction are difficult to solve
But there is actually an imitation stone finish – PU stone
I heard that it can be done “with falsehood and truth”
It has been widely used
So, is this really the case?
Because many buildings are mainly wooden
Pu stone is widely used in the decoration of building facades
It’s just not well known to the public
Today I will take you to decrypt this kind of thing
Such a realistic imitation stone finish – “PU stone”
What kind of material is it?
What is PU stone?
Let’s start with its original components
The Chinese translation of “pu” is polyurethane
Full name polyurethane
It is the one that contains repeating carbamate groups on the backbone
A collective term for macromolecular compounds
It is made up of organic diisocyanates
Or more isocyanates and dihydroxyl groups
or polyhydroxyl compounds are polymerized to form polyurethane materials
It has a wide range of uses and can replace rubber, plastic, nylon and other products
The characteristics are as follows:
(1) Long service life and reduced cost
(2) Temperature resistance is minus 20 degrees ~ high temperature 120 degrees
(3) Polyurethane products are non-polluting, non-toxic and odorless.
From the perspective of raw materials
PU stone is more like a cross-border new material,
Apply well-known materials to the decoration materials that restore real stone.
In terms of process, the raw materials are pressed through the mold, and at the same time, the inside of the mold is colored.
Usually the same type of appearance will develop 2-4 sets of molds,
The shape of all molds is molded according to real stone to achieve a more realistic splicing effect,
The surface is then sprayed and protected with water-based environmentally friendly coatings that are waterproof on the exterior wall.
What are the product types of PU stone?
So what are the specific categories of PU stone?
All cultural stone modeling PU stones are available
For example, in our traditional concept
Great wall stone, tile board, flowing water stone, etc
In addition, there are more distinctive ones
Concrete cement slab, mushroom stone.
The most characteristic style is the stone skin
The effect is close to that of some classic cases
The uneven stone shape used
We all know that
The comprehensive cost of original ecological rough stone is relatively high
In addition to the material itself
During construction, it is also necessary to build a steel frame structure
And it consumes huge manpower and material resources
Then, at this time, pu stone becomes a substitute
The size and length of regular models such as Great Wall Stone and flowing stone
It ranges from 1115~1200 and 180~310 in width
The conventional sizes of concrete cement slabs and mushroom stones are
1200*600、1200*450
The regular size of the stone skin is
2400*800、2400*300、1200*600
Performance characteristics of PU stone:
· Fast ·
Can be used on almost any dry flat substrate in the room
Direct installation time and the time period required for the entire project
It takes far less time to install than traditional cultural stone products
· Lightweight ·
Due to the use of high-tech materials, it is lightweight
No need for the cooperation of other machinery, the installation can be completed by a single person
The construction process of PU stone
So let’s talk about the construction part.
The construction process of pu stone is very simple
It only needs to be applied on a flat blank wall
And due to its lightweight peculiarity
The site can be cut at will according to the design effect
This does save a lot of labor and time costs
