In the embodiment detailed reference to explain the present invention according to a powdery composition which is a thin liner [ppwum seven accompanying drawing, so that the described with reference to attached drawing, identical or corresponding components and the same drawing number local description dispensed the on-sensors other.

In addition, hereinafter used number 1, number 2 same or corresponding components such as term for distinguishing which sends the identification symbol, the same or corresponding components number 1, number 2 defined by terms such as are not correct.

In addition, coupling the circular, provided to secure contact between each of the components, but only when in order to physically direct contact between each of the components, each other interposed between components, and other configurations when the respective general outline to electrically connected to components so as substrate.

The description of the invention method uses a value of IUPAC (International Union of Pure and Applied Chemistry) name of English names are used in.

In the above-mentioned shotcrete door number point for solving alternatively thin [ppwum seven liner (Thin Spray provided on Liner, hereinafter TSL) is used possible disclosed.

[Ppwum seven liner thin polymer (polymer) organic compound-based material and a covering being tagged order based on spraying for reinforcing rock and rock surface are disclosed.

The TSL rock surface attachment strength, excellent tensile strength material characteristic is resource development in the field of rapid supporting and maintaining effect applied for replacing etc. shotcrete and a cylindrical rib space support material. In particular, 3 - 5 mm less than maximal thickness strength of general TSL shotcrete as 10 mm thickness is very thin when compared features.

In addition TSL is ready mix (ready-a mix) form of hopper (hopper) placing the packaging because the reflected light is introduced to the shotcrete alternatively batch plant (batch plant), as well as pouring down very compact since well minimize low pressure air are disclosed. In addition rock surface because of excellent in bonding force minimize dust and prevent leakage and reduce rebound can be [pwung[pwung] rock with the lower disclosed.

In addition, function as well as the supporting and maintaining material utilizing as the TSL, such as weathering of rock (non-structure) is utilized as a coating material for preventing or excavating rock surface can be utilized as [ppwum seven waterproof material (sprayable waterproofing membrane).

However polymeric material is a material formed on the TSL since shotcrete compared to expensive, pouring process of polymer material is highly efficient as well as when the target is mirror number aspects (dewatering) smoothly from an early stage supporting and maintaining performance will not be difficult.

Among other things like number TSL papers or patent disclosure material associated with small studies not only chassis portion as a vending machine for a foreign number TSL situation lyric making substantially a driver or operator are disclosed.

The present invention refers to the development of a chassis and a voice recorder TSL for specific composition and composition ratio number under public affairs powdery TSL a broadcast receiver.

TSL 1 component according material mix powder charge, powder and liquid are mixed 2 component, the liquid component can be divided into 2 have different 2 are mixed.

Generally 2 component liquid, if first liquid component before mixing the powdery components are a powder material is charged into a mixer and, in the case of a cement material powder 1 component prior to adding water and powder polymer combination first accomplishing.

The TSL 2 component in using expensive liquid condensation can be rapidly dust and oil in rebound acid but, as compared to the powder material transmits related difficult since in the present invention called number aspects and diameter in number the ball to thin [ppwum seven liner composition powder target substrate.

In the present invention [ppwum seven liner composition be optimal combination thereof are thin powdery material, Chang et al. (2013) duplication of TSL 2 is carried out based on analysis results of two component material of the lower end of the chemical formula 1 have total 11 test combination among two preliminary conditions and efficient combination of a testing condition was relatively relatively combination total 4 the lower end of the her (also 1).

The polymer content of 60 - 65% has been transformed into a precompounding testing for promoting the expression of early strength on his adding anhydrite and CSA (Calcium Sulfo provided Aluminate) (anhydrous gypsum).

In addition TSL ulexite colemanite (colemanite) number for the expression performance of auxiliary material in polymer emulsion, more in number well column sword (Welan gum), oxalic acid (oxalic acid) powder has a number like phase correction strength in him. General portland cement (OPC) was added on inorganic coupling curing number include alumina cement.

In the case of combination of conditions in Figure 1 H 1% alumina cement component for improving performance of a silicide layer by car [phyum (silica fume) reduces shotcrete instead of substitute material is disclosed embodiment a test was replaced by the HPA (High-a Performance Admixture) 25%.

[Ppwum seven powder test method for evaluating thin liner composition among various mechanical properties tensile testing (ASTM D638) precompounding test conditions a direct most representative embodiment of Figure 1 to him. Results of this test, when compared to the material of TSL 2 foreign product (of Figure 2 T and M) at 7, 9 and 10 times greater than the resolution of soft (ductility) once for the combination condition needs ETEC.

In the case of combination conditions relatively large tensile strength but flexible characteristics of destruction H appears to be most undervalued (2, 1a also). While, at 7, 9 and 10 at once test combination conditions similar to that of the tensile strength 28 material age among foreign product TSL material but T, all EFNARC precompounding conditions (2008) for use in supporting and maintaining material is defined minimum tensile strength material age is less than 7 and TSL 2 mpa expression of body as required didn't performances (2, 1b also).

As in the above-mentioned precompounding performed from results of this test, tensile strength and ductility properties [ppwum seven early powdery material age needs to be thin liner composition has been confirmed.

In the present invention the combination of same with 3 2 replacement start width also conditions such as fatigue strength. The thin [ppwum seven liner composition to enhance polymer content of 65% increasing the powdery soft plastic, material age 7 for increasing the tensile strength of the cement, and anhydrite and modify his CSA for the repairing material.

In particular, combination conditions N1 N2 1% as compared to the well column it will be black to enhance viscosity cement ratio increased for the combination condition start width made from the 1% applied. N2 combination start width in the case of conditions to enhance tensile strength ratio instead of 2% increase relatively early use of CSA, CSA (pot life) and therefore word number in short time due to material immiscible with well column sword more in number for correcting strength no into contact with oxidizing decontamination. In addition serves to enhance toughness combination conditions with respect to the increased quantity for call [ley it rolls up but this [thu start width and cross-N2 1% polymer emulsion.

Hereinafter the present invention according to the composition [ppwum seven powdery thin liner is described evaluation result therein.
