Travertine, saab and resin properties and dimensions

Travertine Properties

 Travertine is one of  the sedimentary rocks that from the bottom of the nash of particles (mainly calcium carbonate) in calcareous caves or around  hot  springs with proper resistance, beauty of design and color, good adhesion to mortar, high sub-and polishing potential, ability to work tools and a wide variety of colors from white and cream to yellow, red and brown.  Due to the presence of elements such as iron, silica and manganese from andjags of this rock, porosity is one of the intrinsic properties of travertine, which is caused by evaporation of carbon gas values and can  only be repaired with putty and sub.  Sound and thermal and suitable mortar grip with it is one of the advantages of porous texture of this stone   (however, the presence   of  stone scope at altitude is absolutely necessary).   Cutting stones in the direction perpendicular  to the layersproduces corruated stones and cutting in parallel directions of  thelayers leads to the production of waveless stone, each of which  has its own beauty, the travertine in a waveless state has an integrated and stronger structure  , but the corrulated stone in the place between the plates (the same lines on the stone) due to  its own beauty. Being is less difficult.

The existence of abundant and rich mines of travertine has led to its extensive production and extraction in the country. The provinces   of Markazi, East and West Azarbaijan, Yazd and Isfahan  are among the most famous travertine mines  in the country, after extraction, the stones were transferred to  the factories as  coupes  and cut using saws or  cut grains in thicknessesof 1-4 cm.  In the  next    step, the processing operations including  resin and subsurfacing on the stones are carried out and then, according to color, design and quality, this stone will be sorted according to its color and quality in the super, privileged, grade 1 and grade 2 categories.   The color of the stone is one of the main factors in its quality, and usually  the brighter stones closest to white and without  impurity veins have a higher price, the important thing is  that usually the color of the travertine is  brighter due to sunlight and its designs are  faded. Therefore, this point should be taken into account when preparing stones  , as well as many lines, halo and  fine veins  after the façade, especially in the upper floors, because of the high distance  is not recognizable because in some cases there is a dramatic price difference between the privileged sample and the 1st degree of a stone and with the optimal choice, it is possible to reduce the possibility of reducing.  Theno-nos of the plan will be possible.

Sub and Resin

The amount of porosity on the surface of the  stone is an important factor in determining its quality,  so that the more porous the stone  , the  cheaper and the more expensive it is,  the more expensive it  is usually used   to fill the  porosity of the stone from cement, roses, bridges, epoxy or UV resin.  Each one has merits and disadvantages.  For example, cement has color fastness and due to the coefficient of expansion and contraction almost the same as stone, it has a good grip with it, but the opaque parts  filled with it in   shiny stones are considered a flaw.  Andthe  rose-roses have made the majority  of  the  stone processing industry using them today, transparency of roses, no need for special equipment, and easy implementation of their merits, which are  usually easy to use  with a card.  Stretched on the surface and dry in front of the  sun.

In most stone factories, bridge esther  resin is used  because of its inexpensiveness, ease of execution, ability to dry in the sun, resistance to sun rays and high viscosity (andhigh viscosity causes drying of the head and less penetration depth in the texture of the stone) and epoxy resin due to higher price despite the quality.  More desirable, more color fastness and higher resistance, less  used KGRed. Also, UV resin  is  one of the new methods that rarely be done  in some factories due  to the  need for UV furnaces.   Because of  the  increase  in the  hazing  of  the noh, the  use of this method is  usually limited to some  high-quality stones at high prices and in other cases has economic justification, the surface of the stone is not only limited to some high-quality stones and in other cases has economic justification  after resin, the surface of the stone in several stages from rough to soft subsurfacing.     The quality  of   the resin consumed at this stage is completely eye-catching and the surface resin is carefully separated  from the surface of the stone using  BKFT materials  with the first contact of the saab head.  In these cases, the stone will be filled with holes again after resin and saab   .

Travertine and marble are usually supplied in two forms: saabed and leathery, in the leather type, usually the pores of the surface of  the  remaining stone  , and only using the saabs and their money, a shiny and velvet view similar to the texture of the fabric or leather is created that  has its own side of the leather,  a method of processing.  It does not belong to a particular surt. These stones are used in façade or indoors and usually due to the lack of resin, the price is less than the sabideh stone.

Dimensions of stone

Travertine in the  market is usually available in the form of 40 lengths (width 40 cm and  variable lengths) and verdict (specified length and width, e.g. 40×40) or in the form of slabs with thicknesses of  1.6 to 2 cm, the slabs of processed stone  in dimensions are usually larger than 120×20 cm, which according to customer’s order is cut  .   Generally, it is in the form of slabs to be cut in the desired dimensions at the destination, because of the possibility of installation in large and seamless sizes, grating and resin, higher saab quality and more thickness usually have a higher price.   Usually, the price of hakami stone is more expensive than 40 lengths due to the higher outlier when cutting about 10-5% depending on the type of stone,  and also the stones with a width of less than 40 cm  have ahigher foot price,  the important thing about the stones is the ruling that if the dimensions increase, the price increase has a very steep slope and  for example,  The 60×60 stone  is much more expensive than the 40×40 stone, the point should be considered in the design of the façade and floor to control the nozzles  .
