Rock wool products are made from natural mineral wool such as basalt and dolomite. The natural rock are melted into melts in cupola at a very high temperature about 1500The highest application temperature is 700 it has characters : sound insualtion ,fireproof ,waterproof and so on. It always used in the construction sound insulation wall,roof , industrial furnace,oven,heat -treating equipment,storage tank and so on.It has characters such as: Superior Fire Resistance Rock wool board is non-combustible, not burn,not smoke and can arrived Class A fire rating and it also has heat preservation. Its highest working temperature is 750 Good Water reprellence: Rock wool products greatly reduced by adding special silicone emulsion water repellent agent, thus ensuring the quality requirement for external wall insulation system. Hydrophobic rate is 99%. Environment Friendly Free from asbestos, CFCS, HFC, HCFCS and other harmful substances to the environment; our rock wool adopt the resin binder. Do not release any toxic gas at high temperature. Construction Application Rock wool was used for building materials , and steel structure insulation soundproof and fireproof used for wall and roof of house Heat preservation for steel structure building For indoor partition wall , Train compartment . Rock wool used for industrial furnace, oven, heat-treating equipment, storage tank, storage groove. power house, flue, petrifaction and oil refining equipment and all kinds of keeping-warm and heat insulation pipelines.
Plastic products, there are all aspects of our lives, on the one hand he brought convenience to our life; the other hand, from a variety of waste plastic generated garbage, but also to our living environment hazards. Based on the intermittent plastic pyrolysis plant, DoingGroup has developed a new type of fully automatic plastic pyrolysis plant. The equipment uses a precise calculation of cracking system, high degree of automation, continuous feeding, continuous slag discharge, 24-hour non-stop Run, without stopping the cooling and then slag. Working process: 1. The first plastic waste into plastic crusher, crushed waste plastic processing. 2. The broken plastic into the automatic continuous plastic cracking equipment. 3. Without any operation, you can get fuel. 4. Equipment produced in the reactor carbon black, will be automatically discharged at the end of the device. The main advantage: 1. Accurately calculate the system to ensure full cracking, high oil yield. Indirect heating, long service life. 3. Continuous feed. Continuous slag discharge, saving time and effort. 4. Automatic, PLC control, save manpower. 5. Pyrolysis reactor with internal rotation device, without the need for regular pause to replace the sealing material. 6. Single handling capacity, small land area.

We have two of the most trusted brands in stock with us, that is PATTA and HP both from TAIWAN. We usually have all the sizes of SelfDrilling Screws in Ready Stock 10*20,10*25,12*25,12*35,12*45,12*55,12*68,12*75 & 12*90 Self-drilling screws mainly has three advantages as following: » Firstly, Self Drilling Screws can save labor. Drilling hole, forming mating thread and clamping home can achieve in an easy operation. It doesn’t require for difficult alignment of two or more elements. » Secondly, Self Drilling Screws can save materials. It only needs one tool for application---screw drive. » Power drills, drill bits and elaborate and costly press tools and their maintenance are eliminated. » Finally, Self Drilling Screws can improve product quality. It ensures correct hole size every time, resulting in better thread engagement and tighter clamp. Self Drilling Screws features Drill Point which has precise cutting edges to improve drill performance with less EFFORT. The Unique Point to Thread design extrudes the metal preventing strip-out and maximizes pullout performance and minimizes back-out. » Drill Point has a unique curved edge at the corner of the drill point. This ensures that the drilling process becomes self-digging making drill penetration effortless. The conventional drill point only facilitates drilling. A knife like corner is created to scrape the steel off. Sufficient pressure has to be applied for more effective drilling making drilling tiring. » non walking drill point provides fast material engagement. Hex Head Self Drilling Screw comes with EPDM washers which provide excellent heat, cold, weather, Ozone, Oil resistance and very good bending strength, wear resistance, repulsive elasticity and compression strength. » Self Drilling Screws are engineered for fast drilling and smooth tapping with less effort. » Self Drilling Screws comes in both Zinc as well as Ruspert® Coating (Anti-Corrosive).
