1、整體外觀

1. Overall appearance

如今市面上比較殘次的透水磚外表都比較粗糙，孔隙十分大。這種透水磚使用壽命比較低，因?yàn)榇罂紫锻杆u的突出“特點(diǎn)”就是容易被塵埃堵死，而一旦被塵埃堵死的透水磚就失去了透水磚的效果與價(jià)值了。

Nowadays, the relatively inferior permeable bricks on the market have a rough surface and very large pores. This type of permeable brick has a relatively low service life because the prominent feature of large pore permeable bricks is that they are easily blocked by dust, and once blocked by dust, permeable bricks lose their effectiveness and value.

2、顆粒分布

2. Particle distribution

透水磚的透水原理是通過(guò)相互包裹的顆?？p隙透水，為保證透水磚的透水量及透水時(shí)效性，顆粒的粒徑搭配要合理，分布要均勻。劣質(zhì)透水磚為了降低成本，原材材料中摻入了大量細(xì)粉狀的黏土和煤灰，其表面、底部、側(cè)面都可以看到顆粒被黏接物粘結(jié)，顆粒不明顯。

The permeability principle of permeable bricks is to penetrate through the gaps between particles that wrap around each other. To ensure the permeability and timeliness of permeable bricks, the particle size combination should be reasonable and the distribution should be uniform. In order to reduce costs, low-quality permeable bricks are mixed with a large amount of fine powder clay and coal ash in the raw materials. The particles can be seen to be bonded by the adhesive on the surface, bottom, and sides, and the particles are not obvious.

3、檢驗(yàn)標(biāo)準(zhǔn)

3. Inspection standards

國(guó)家對(duì)透水磚的透水時(shí)效、透水速率和力學(xué)性能上其實(shí)都有嚴(yán)格的規(guī)定和要求。

The country actually has strict regulations and requirements for the permeability time, permeability rate, and mechanical properties of permeable bricks.

我們?cè)谶x購(gòu)時(shí)，可以讓廠家出示該產(chǎn)品的數(shù)據(jù)檢驗(yàn)報(bào)告，看透水磚的性能指標(biāo)是否達(dá)到國(guó)家標(biāo)準(zhǔn)。請(qǐng)謹(jǐn)記：這3個(gè)指標(biāo)是衡量透水磚質(zhì)量?jī)?yōu)劣的“試金石”。

When making a purchase, we can ask the manufacturer to provide a data inspection report of the product to see if the performance indicators of the permeable bricks meet national standards. Please remember that these three indicators are the touchstones for measuring the quality of permeable bricks.

4、批量質(zhì)量

4. Batch quality

透水磚的質(zhì)量不能只看單個(gè)產(chǎn)品的質(zhì)量，要看批量產(chǎn)品的質(zhì)量。劣質(zhì)透水磚由于廠家工藝管理、原材料控制等把控不嚴(yán)的原因，質(zhì)量波動(dòng)會(huì)比較大，特別是規(guī)格、色差、強(qiáng)度、透水性等容易出現(xiàn)大的波動(dòng)，從而影響產(chǎn)品質(zhì)量的穩(wěn)定性。

The quality of permeable bricks should not only depend on the quality of individual products, but also on the quality of batch products. Due to the lack of strict control over the manufacturer's process management and raw material control, low-quality permeable bricks can experience significant quality fluctuations, especially in terms of specifications, color differences, strength, and permeability, which can affect the stability of product quality.
