heating (1000 ℃), vaporization of moisture in the ore, in softening the vitreous of ore containing internal expansion, forming a porous structure, volume expansion of 10-30 times, expanded perlite, expanded perlite bulk material as aggregate, adding the binder in the preparation, screening, compression molding, drying and other processes made ​​of insulation board. Perlite insulation board to solve all types of building roof insulation, thermal insulation in one of the technical problems, saving a lot of construction and maintenance funds.<br /> Rock wool in natural basalt as the main raw material, after high-temperature melting artificial inorganic fiber made ​​by the high-speed centrifugal equipment, while adding a special binder oil and dust, and then by heat curing, made into a variety of specifications, requirements of rock wool insulation products. Rockwool products are widely applicable to the construction, petroleum, electric power, metallurgy, textile, defense, transportation and other industries, is a tank, boiler, flue, heat exchangers, fans, travel and other industrial equipment insulation, sound insulation the ideal material. Rock wool board high temperature of 650 degrees.<br /> Both the price difference is large, expensive wool board and rock wool absorbent ability the insulation performance relative to the perlite board worse. Although rockwool fire performance up to high-quality, but because of its serious harm to the human body, there is a carcinogenic problem, some developed countries have strict restrictions on the use rockwool, long-term inhalation of meningitis and rockwool dust can lead to endobronchial emphysema, contact dermatitis, and other symptoms. From industry personnel health considerations, the use should be strictly limited. In summary, perlite board wool board replacement product.</p></div> </div> <div style="background-color:#F7F7F7;margin-top:15px;padding:10px;">Previous：没有了<br /> Next：<a href="/html/xwzx/jszs/1338.html" title="Perlite in the technical aspects of the production of explosives">Perlite in the technical aspects of the production of explosives</a> <div> <div style="text-align: right;">【<a href="javascript:window.print();">Print</a>】【<a href="javascript:window.close();">Close</a>】</div> </div> </div> </div> </td> <td width="230" align="right" valign="top"><table width="215" border="0" cellpadding="0" cellspacing="0" class="right_k"> <tr> <td width="213" align="left" class="right_t_bg">About Us</td> </tr> <tr> <td align="left"><div id="right_list"> <ul> <li><a href="/html/gsgk/gsjj.html">Company Profile</a></li> <li><a href="/html/list_1236.html">Honor</a></li> <li><a href="/html/gsgk/qywh.html">Culture</a></li> <li><a href="/html/gsgk/zzjg.html">Organization</a></li> <li><a href="/html/gsgk/zjlzc.html">Manager Speech</a></li> </ul> </div></td> </tr> </table> <table width="215" border="0" cellpadding="0" cellspacing="0" class="right_k" style="margin-top:15px;"> <tr> <td align="left" class="right_t_bg">Customer Service Center</td> </tr> <tr> <td align="left" class="line25"><p><strong class="red">Xinyang city centertriumph insulation material Co.,Ltd.
