花崗岩介紹 GRANITE INTRODUCTION

花崗石 - 火成岩中的深成岩；深成岩，係指未噴出的岩漿在地下深處數百到數十公里高壓冷卻固結而成的岩石，後來經過地殼隆升和侵蝕才露出地面的，其結晶體彼此間緊密結合，使得結構緊實、堅固。經過百萬年長時間的孕育，其原子結構已經達到非常穩定的狀態。
隨著科技業精益求精的發展下，其所使用的量測、加工與設備等所要求的精準度及穩定性也更加嚴格。因此，花崗石材的抗壓強度高，與金屬材料（如鑄鐵、鋼及鋁等）比較下，花崗石極耐振動且沒有生鏽之疑慮等，種種優勢，被認定製作高精密度的檢測儀器或是製程設備理想的應用材料，更奠定了石材在科技業界舉足輕重的地位。
由於天然花崗岩產地的不同，其物理性質及特性也不盡相同，經過德國以及日本的原物料物性分析下，以來自印度出產的印度黑以及南非出產南非淺黑的石種，被同意認定適合作為精密花崗岩的優先選用材料。本公司所採用的天然花崗岩就是依照世界先進國家分析出來的數據以及其所採用的原物料，不論是密度、彎曲強度、吸水率、抗拉抗壓強度的優越條件下，皆是業界首選！

Granite – The plutonic rock of igneous rocks, which is the lava that bears hundreds of kilometers underneath the ground that did not eject. These lava beneath the ground had been cooled down with high pressure and form the property of rock. After the crustal uplifting and erosion, these plutonic rocks then exposed on the ground. Its crystal closely integrated with one and other, which tightened and strengthened its structure. After millions of years of gestation, its atomic structure has reached to a very stable state.
With the evolution of the technology; the equipment and facilities use to produce technological products had been required with much higher and stricter standard in terms of accuracy and consistency. In comparison of the metallic materials, granite itself owns the benefits of the resistance against high pressure, antirust, non-magnetic, etc. In the recent tendency, this natural material has played a strong role in the technology industry.
There are different granite quarries sitting among the world; due to different locations, the physical property and characteristics also varies. After a detailed physical property analysis from German and Japan, they had found the most suitable material to product precision measurement products are the black materials from India and South Africa. Chuan Ya Marble Precision Business Division has produce its products using materials accordingly to these analysis and ensure the quality is competitive to the leaders of this field.
