低質(zhì)人造石電梯門套方法有哪些？
一、觀，即肉眼觀察石材的表面結(jié)構(gòu)。一般說(shuō)來(lái)，均勻的細(xì)料結(jié)構(gòu)的石材具有細(xì)膩的質(zhì)感，為石材之佳品；粗粒及不等粒結(jié)構(gòu)的石材其外觀效果較差，機(jī)械力學(xué)性能也不均勻，質(zhì)量稍差。另外，天然石材由于地質(zhì)作用的影響常在其中產(chǎn)生一些細(xì)脈、微裂隙，石材易沿這些部位發(fā)生破裂，應(yīng)注意剔除。于缺棱少角更是影響美觀，選擇時(shí)尤應(yīng)注意。
1、 Observation refers to observing the surface structure of stones with the naked eye. Generally speaking, stones with a uniform fine material structure have a delicate texture, making them excellent for stone materials; The appearance effect of stones with coarse and unequal grain structures is poor, and their mechanical and mechanical properties are also uneven, with slightly poor quality. In addition, due to the influence of geological processes, natural stone often produces some fine veins and micro cracks in it, which are prone to fracture along these parts, and attention should be paid to removing them. As for the lack of edges and corners, it is particularly important to pay attention when selecting.
二、量，即量石材的尺寸規(guī)格，以免影響拼接，或造成拼接后的圖案、花紋、線條變形，影響裝飾效果。
2、 "Quantity" refers to the measurement of the size and specification of the stone to avoid affecting the stitching or causing deformation of the patterns, patterns, and lines after the stitching, affecting the decorative effect.
三、聽(tīng)，即聽(tīng)石材的敲擊聲音。一般而言，質(zhì)量好的，內(nèi)部致密均勻且無(wú)顯微裂隙的石材，其敲擊聲清脆悅耳；相反，若石材內(nèi)部存在顯微裂隙或細(xì)脈或因風(fēng)化導(dǎo)致顆粒間接觸變松，則敲擊聲粗啞。
3、 Listening means listening to the knocking sound of stones. Generally speaking, stones with good quality, dense and uniform interior, and no micro cracks, have a clear and pleasant knocking sound; On the contrary, if there are micro cracks or fine veins in the interior of the stone or if the contact between particles becomes loose due to weathering, the knocking sound is rough and dumb.
四、試，即用簡(jiǎn)單的試驗(yàn)方法來(lái)檢驗(yàn)石材質(zhì)量好壞。通常在石材的背面滴上一小滴墨水，如墨水很快四處分散浸出，即表示石材內(nèi)部顆粒較松或存在顯微裂隙，石材質(zhì)量不好；反之，若墨水滴在原處不動(dòng)，則說(shuō)明石材致密質(zhì)地很好。
4、 Trial, that is, using a simple test method to test the quality of stone materials. Usually, a small drop of ink is applied to the back of the stone. If the ink is quickly dispersed and leached, it indicates that the internal particles of the stone are loose or there are micro cracks, and the quality of the stone is poor; On the contrary, if the ink droplets remain in place, it indicates that the stone is dense and has a good texture.
