石英石板材是由90%以上的石英石填料加百分之几的树脂及辅料在真空振动加压成型,由于石英石在生产配方中含量较高,所以叫做人造石英石。 石英石首先是由意大利百里通研制生产,百利通石英石生产设备,一条生产线的投资1.7亿元人民币,韩华出于市场考虑与百利通签署的额外的协议——在2010年前,百利通的设备不允许卖到中国。

Quartz plate is made of 90% or more quartz stone filler plus a few of the resin and accessories in the vacuum vibration compression molding, due to the high content of quartz stone in the production formula, so called artificial quartz stone. Quartz stone is first developed by the Italian Breton production, Pericom quartz stone production equipment, a production line investment 1.7 billion yuan Hanwha for the market to consider and Pericom signed the additional protocol -- in 2010, Pericom equipment is not allowed to sell to China.

前几年国内有部分厂家通过模仿,改良自主研发设备。生产石英石板材,由于设备运行不稳定,设备维修率高,生产的板材合格率不高,主要有针孔、杂质、纸皮凹陷、色差、变形等质量缺陷。通过这两年来技术不断的完善,现已解决了板材质量问题。而人造石英石产品也得到了广大消费者的认可

A few years ago, some domestic manufacturers through the imitation, improvement of independent research and development equipment. Production of quartz stone plate, due to the instability of the equipment operation, high rate of equipment maintenance, sheet metal production qualified rate is not high, mainly quality defect of pinhole, impurities, cardboard sag, chromatic aberration and distortion. Through the past two years of continuous improvement of technology, has solved the problem of plate quality. And artificial quartz products have been recognized by the vast number of consumers

。但是,目前行业中还有大部分人没有掌握好关键技术,生产出板材不合格,树脂含量高,板材有气孔,要通过修补表面来处理。是必会影响石英石板材品质,给客户留下不好的影响,导致石英石行业健康发展。

. However, the industry is still in the majority of people do not have a good grasp of key technologies, the production of the plate is not qualified, high resin content, plate with holes, to be treated by repairing the surface. Is will affect the quality of quartz plate, to the customer left a bad impact, leading to the healthy development of the quartz stone industry.

要想做好人造石英石板材,以下四点是关键。

To do a good job in artificial quartz plate, the following four points is the key.

一、 设备的选型 现石英石定厚抛光设备技术已成熟。压机是生产石英石关键设备,而有些设备制造厂家误认为偏激力越大越好,压机配备振动电机不合理,导致大马拉小车,使设备运行不稳定,维修故障率较高。而有些制造厂家为了降低设备维修率改用多台小型振动电机。虽然设备维修率低了,但是,板材生产树脂含量偏高。多色板造成渗色现象。因振动电机过多,不同步,导致偏激力一部分内消耗。所以一台好的压机要具备以下几个特点。

A selection of equipment, the quartz Dinghou polishing equipment technology has matured. Compressor is the key equipment in the production of quartz stone, and some equipment manufacturers mistakenly believe that extreme force is better, the press is equipped with motor vibration is not reasonable, lead to the big car Mara, the unstable operation of equipment, maintenance rate is higher. And some manufacturers in order to reduce the maintenance rate of equipment to switch to more than a small vibration motor. Although the equipment maintenance rate is low, but the plate production of resin content is high. Multi color caused by bleeding phenomenon. Due to excessive vibration motor, synchronous, extreme power consumption part. Therefore, a good press to have the following characteristics.

〈一〉设备运行稳定,维修率低;

The equipment operation is stable and the maintenance rate is low;

〈二〉真空密封性好;

< two > the vacuum sealing is good;

〈三〉配方中树脂含量低;

The low resin content in the formula of "three";

〈四〉操作方便,维修方便。

The operation is convenient and the maintenance is convenient.

二、 原辅材料的把关 巧妇难为无米之炊,在进原材料之前,尽量找信用度比较好的供应商,树脂、石英砂粉、玻璃、色浆、固化剂、偶联剂是我们生产石英石常用的原辅材料。

Second, raw and auxiliary materials to ensure the cleverest make bricks without straw, before into the raw materials, try to find good credit suppliers, resin, quartz sand powder, glass, printing ink, curing agent, coupling agent is our production of quartz stone commonly used raw and auxiliary materials.

〈一〉.树脂.

A resin.

1. 全名:不饱和聚脂树脂

1 Name: unsaturated polyester resin

2. 聚合物固含量≥65%

The 2 polymer solid content is more than 65%

3. 树脂黏度850~1200Mpa.s(根据温度调整树脂黏度)

3 resin viscosity 850 ~ 1200Mpa.s (according to the temperature adjustment of resin viscosity)

4. 树脂发热峰温度:160℃~170℃

4 resin heating peak temperature: 160 degrees Celsius to 170

5. 外观:石英石专用树脂,无色,无杂质,半透明液体.

5 appearance: quartz stone resin, colorless, no impurities, translucent liquid.

〈二〉.石英粉

< two >. Quartz powder

1. 细度要求240目~400目

1 fineness required 240 mesh to 400 mesh

2. 白度要求≥95度(用树脂加石英粉调成糊状,要求白色或半透明合格,发黑,发黄为不合格)

2 white degree is greater than or equal to 95 degree (with resin and quartz powder into a paste, white or translucent yellow to black, qualified, unqualified)

3. Si02的含量≥98%

3 Si02 content is more than 98%

〈三〉石英砂

Quartz sand three

1. 颗粒均匀,无杂质,异物,不能含金属铁.

1 uniform particles, no impurities, foreign body, can not contain metal iron.

2. 4~40目且颗粒不能有风化石.

2.4 ~ 40 mesh and particles can not have wind fossils.

〈四〉玻璃

Four glass

1. 透明玻璃,要求无碎纸,杂物及其它杂色玻璃颗粒.

1 transparent glass, no paper, debris and other variegated glass particles.

2. 镜玻.要求不掉色,灰底、白底匀可。

2 mirror. Do not fade, gray bottom, white uniform may.

〈五〉 色浆 要求直接用色浆,因色粉不能完全分散,会导致板材色差.

"Five" requirements directly with the paste paste, because the toner can not fully dispersed, will cause the plate color.

〈六〉 固化剂

Curing agent for "six"

中温固化剂:过氧化二乙基已酸叔丁酯.(OT) 室温引发剂:过氧化甲乙酮 促进剂:环烷酸钴.

Medium temperature curing agent: peroxide has two ethyl tert butyl acrylate (OT) at room temperature. The initiator: methyl ethyl ketone peroxide accelerator: cobalt naphthenate.

〈七〉 偶联剂

Coupling agent seven

1. 硅烷偶联剂(KH-570)

1 silane coupling agent (KH-570)

三、 合理的级配比例。 配方中合理的级配比例,颗粒堆集密度是生产优质石英石板材的关键。比例不合适,会造成板材变形,气孔,开裂等质量问题。有很多石英石厂家的技术都是靠从别人那里拿到配方,或者设备厂家提供配方。笔者发现就是同一个厂家生产出来的压机,由于加工、安装、电流误差,都会造成压机压力不一样。 而技术配方必须现场调整,才能生产合格石英石板材。 四、 生产现场工艺操作规范

Three, reasonable gradation ratio. In the formula, the density of the particles is the key to the production of high quality quartz. Proportion is not appropriate, will cause the plate deformation, porosity, cracking and other quality problems. There are a lot of quartz stone manufacturers are relying on the technology from others to get the recipe, or equipment manufacturers to provide formula. The author found that the same factory produced by the press, because of the processing, installation, current error, will cause the pressure is not the same as the press. Technical formula must be adjusted in order to produce qualified quartz plate. Four, production site process operation specifications

1、 制订生产工艺流程,建立岗位作业指导书。

1, to develop the production process, the establishment of job guidance.

2、 同批板材的颗粒粉料必须预混和才能投入使用,因石英粉是天然矿石,每一包都有不同程度色差。

2, the same batch of sheet metal powder must be pre mixed in order to put into use, because the quartz powder is a natural ore, each package has a different degree of color.

3、 石英石板材在生产过程中,尽量避免使用金属工具,因金属跟石英石摩擦导致发黑。

3, the quartz plate in the production process, to avoid the use of metal tools for metal with quartz friction lead to black.
