水洗棕剛玉磨料優點：

粉塵小：用水洗金剛砂進行表面噴磨處理，由于它的比重比較高，所以在噴射過程中產生的粉塵比較少，這一點保證了操作員的健康和安全，提高了操作員的能見度，與礦渣相比較（礦渣形成過程中是用冷水甚至是海水進行高溫冷卻，所以形成的是玻璃相結構，具有易碎性），由于礦渣比較脆，在噴磨過程中，易被撞碎形成小顆粒，由于礦渣比重比較小，造成小礦渣顆粒懸浮在空氣中，造成對環境的污染，同樣，石英砂也是一種非常易碎的磨料，在噴磨過程中，會產生大量的對人體有害和對環境有嚴重污染的硅酸粉塵，這種粉塵一旦被人體吸入，很容易導致硅肺病甚至是癌癥。

是水洗廠牛仔服.水切割行業優質的配砂。本廠產品自銳性好,邊角鋒利;在不斷粉碎中形成新的棱刃,介殼狀斷口硬度均勻,對所磨器具、物件不會造成劃傷現象，而且化學成分穩定,耐酸堿,具有其他磨料和人工合成磨料 的優勢。并且本廠產品研磨時間短，效益高，但價格低廉，這些可以禰補壽命短而不足。

?

率：水洗金剛砂在一定壓力作用下，能夠大量快速地用鋒利的棱角撞擊物體表面，所以被視作是一種非常快的噴磨方式，在氣流中顆粒加速度和速度是慣性和顆粒大小產生的作用，越小的顆粒，加速越容易，因此能產生更高的沖擊力沖擊物體表面，從而產生一個非常高的清洗速度通常情況下，這個速度（ｍ2/h r）比其他常規磨料快兩倍。

The use of the brown fused alumina,

Brown fused alumina teeth called industry: mainly used in refractory materials, grinding wheel, sand blasting.

1. Sand corundum, sandblasting abrasive hardness is moderate, high packing density, no free silica, than major, good toughness, Mr Kay brown fused alumina is the ideal "environmental protection" type sand blasting materials, widely used in aluminum, copper profile glass, water wash jeans precision molds, and other fields; Level 2. Free grinding, grinding abrasive, applied to the tube, optical glass, silicon single crystal with glass, mirror, clock and watch, crystal, jade and so on in the field of free abrasive, grinding is adopted widely in the domestic advanced materials; 3. Resin abrasive, abrasive has color appropriate, good hardness and toughness, suitable particle cross section type and keeping degree blade, used in resin abrasive effect is ideal; 4) is coated with abrasive, abrasive abrasive paper, gauze production factory production of raw materials; 5. Brown fused alumina filler - is mainly used for automobile brake parts, special tires, special construction products such as led can be used as building highway pavement, airport runway, wharf, parking lot, industrial floor, wear-resisting material such as sports venues; 6. The filter medium, is a new kind of application field, abrasive using granular grinding as filter medium, the bottom of the bed, purify drinking water or wastewater is a new type of water filtration materials at home and abroad, especially in non-ferrous metal ore dressing, oil drilling mud weighting agent:

7. Hydraulic cutting - an abrasive abrasive cutting medium, rely on high pressure water jet cutting, basic application in the oil (gas) pipelines, steel parts such as cutting, is a new type, environmental protection, safe way of cutting.

Customer base: washed denim sandblasting factory workshop repairing yard shipyard steel structure factory powder factory our sandpaper, ShaBuChang crystal glass industry building floor steel hardware industry electronics industry qi car manufacturing coast terminals, parking lot, hospital, stadium. Sand industry and other cooperation required floor aggregate content to all types of users and abrasive. 8. The product is reliable, stable performance, good quality, easy to use.

Washed corundum abrasive advantages:

Little dust: wash emery grinding surface spray processing, because of its specific gravity is higher, so less in the injection process of dust, it ensures the operator's health and safety, and improve the operator's visibility, comparing with the slag, slag formation in the process of high temperature is even in cold water is seawater for cooling, so the phase structure is formed by glass, have fragility), because slag is brittle, in the process of jet mill, easy to be smashed to form small particles, due to the relatively small proportion of slag, cause little slag particles suspended in the air, causing pollution to the environment, also, quartz sand is a kind of very friable abrasive, in the process of jet mill, will produce large amounts of harmful to human body and there are serious pollution to the environment of silicate dust, once the dust is inhaled, it is easy to cause silicosis disease and even cancer.

Are jeans washing plant. Water cutting industry quality with sand. Our products are good self-sharpening, sharp edges; Form new blade edges in the shattered, conchoidal fracture surface hardness is uniform, to the grinding tools, objects will not cause scratch phenomenon, and chemical stability, resistance to acid and alkali, and other abrasive and artificial abrasive irreplaceable advantages. And our products are milling time is short, high efficiency, but the price is low, these can fill your life short and insufficient.

Efficiency: water emery under certain pressure, to a large number of rapidly with a sharp impact surface edges and corners, it could be seen as a very fast way of jet mill, particle acceleration and velocity in air is inertia and the role of particle size, the smaller the particles, accelerate the easier, thus can produce higher impact shock surface, to produce a very high speed of cleaning - typically, this speed (m2 / h r) two times faster than other conventional abrasive.

Packaging and shipping instructions:

gongyi city every abrasives factorybag of 25 KGS net each white woven bag packing. Stored during transport to prevent damaged packaging, in order to avoid loss or mixed with sundry. Unfavorable transportation stacked together with supporting and other filter material.
