Q:Will the CAD used to note the material line how to draw? Is the beginning with a small dotted line, there are shortcuts What is the hope you prawn help brother Thank you
In the lead to set, the arrow type to "point" can be, and you use the CAD which version of it, find a matching version of the Tsinghua Tianhe plug-in, installed, it is very easy
Q:Does anyone know where to get the model of building materials?
To the large building materials market to collect on the line, but also to the large building decoration company.
Q:A variety of materials required for interior design, price and use
Each place the price is different, and the price of each brand is not the same shape
Q:Many people say that online building materials can not touch, not particularly Kaopu, do you think?
This depends on what kind of platform you levy ah, not necessarily do not fly ah, some platforms are dedicated to selling building materials, it is not bad
Q:PS material is not subject to ultraviolet light or LBD light will be yellow
PS material scientific name polystyrene polystyrene is a styrene monomer by free radical polycondensation synthesis of the polymer, the English name for the Polystyrene referred to as PS
Q:What is the difference between pu lines and gypsum lines in European-style ceiling decoration?
Gypsum line PU line indoor use more. The The GRC wall with more gypsum line direct brush or spray latex paint do not need to putty. The The Most of the PU line does not need to brush any paint, are in the factory are doing the paint ,,, GRC used in the external walls, seams with mesh cloth and pure water to repair the water, and then putty, brush or In the case of most of the case, the plaster & lt; PU & lt; GRC is basically the same.
Q:Can the tile wall and the roof be made of gypsum wire
Your mistake is that the restaurant wall is no need to be tiled. The walls of this space are different from the kitchen or the bathroom. This common sense you do not have, now cause a problem. What kind of angle is not enough, are enough ugly. Technically can not handle. The only way to deal with only: the use of 20 U-shaped white steel buckle, the grass-roots needs of small wooden bottom, the carpentry will do, white steel buckle the surface to protrude wall brick 2MM, which is the technical requirements of the seams.
Q:Is it the same thing to change the rewarming line of the refractory and to change the permanent line
Mainly in the firing process, due to uneven temperature or lack of time and other effects, so that the firing is not sufficient, in its long-term use, by high temperature, some physical and chemical changes will continue, so that the refractory The volume of the material expands or shrinks This change has a great damaging effect on the masonry of the thermal kiln, and it is necessary to strengthen the firing control in the production of the product so that the index is controlled within the standard even to a smaller value Commonly used refractory baking line changes in the national standards are provided Rebirth line changes, also known as residual line changes, refers to the firing of refractory material heated to high temperature, the length of the irreversible changes occurred The specific definition is that the refractory sample is heated to the specified temperature The residual expansion or contraction of the length after cooling to room temperature for a certain period of time Heating constant line change rate refers to the firing of the fire-resistant ball again heated to the specified temperature, heat for a certain time, cooled to room temperature after the residual expansion and contraction Positive sign "+" means expansion, negative sign "-" means contraction It is an effective process to increase the firing temperature and prolong the holding time in order to control the change rate of the permanent cooling of the refractory ball within the standard even lower But it should not be too high, otherwise it will cause the deformation of the fireball, glass vitreous, reduce the thermal shock resistance
Q:What is the material for the zebra crossing? Can the cement floor be slippery?
Zebra is a common white paint brush, the zebra line is divided into three kinds of materials, one Road paint, the service life is relatively short, generally three or four months to brush a paint, because it is reflective, and may rain and snow There will be some slippery, the current use of the city is the most road paint; the second is the line with the line, had to trace the history of the United States and the United States is not slippery, but with the use of the surface of the reflective surface will wear , Pedestrians will feel more slippery, but the road with a long life, usually two years, the construction of the most convenient, the price is also the cheapest; Third, hot melt material, that is, netizens said non-slip material, the surface Not very flat, the largest coefficient of friction is the best material, life is two years, but the laying of the need to spend a lot of manpower, and hot melt material prices are relatively high.
Q:What kind of material is used on the road zebra crossing
