The present invention relates to the technical field of waterproof materials, and particularly to a high-strength wind-resistant skid-resistant waterproof underlayment. The high-strength wind-resistant skid-resistant waterproof underlayment comprises a first non-woven fabric layer, a first film layer, a first asphalt layer, a gridding cloth layer, a second asphalt layer, a second non-woven fabric layer, a second film layer and a third non-woven fabric layer laminated successively; the first film layer and the second film layer are waterproof elastic films respectively. The object of the present invention is to provide a high-strength wind-resistant skid-resistant waterproof underlayment. The waterproof underlayment formed by structures such as a first film layer and a second film layer and the like can be fixed through nails on a roof made of a wood structure, etc., and the construction is quick, convenient, and labor-saving, and the waterproofness is good.

A trestle mat construction panel configured for use with building equipment and a method of manufacture and use thereof. The trestle mat construction panel is preferably formed of a partially hollow core body and strong support material to allow the construction panel to be easily placed and moved and to support various materials, such as construction equipment including cranes and the like, when in use.

Materials and methods for mitigating passive intermodulation. A membrane for reducing passive intermodulation includes a first polymeric layer, a second polymeric layer, and a continuous metal layer encapsulated between the first and second polymeric layers. A self-adhesive radio frequency barrier tape includes a waterproof polymeric top layer, a metal-containing layer adhered by an adhesive layer to the polymeric top layer, a pressure sensitive adhesive layer adhered to the metal-containing layer, and a release liner on a bottom surface of the pressure sensitive adhesive layer. A method of mitigating passive intermodulation includes passing a probe over an area of interest, the probe being sensitive to an intermodulation frequency of interest, and identifying a suspected source of passive intermodulation when the amplitude of the probe output exceeds a threshold at the frequency of interest. The method further includes covering the suspected passive intermodulation source with a radio frequency barrier material.

An insulation product for a pipe or vessel having at least one aerogel insulation layer, an additional insulation layer positioned around the at least one aerogel insulation layer, and a protective cladding layer surrounding the at least one aerogel insulation layer and the additional insulation layer.

The invention provides a waterproofing membrane which does not require a removable release sheet but which nevertheless bonds to post-cast concrete and facilitates water-tight sealing at membrane-to-membrane overlaps. The waterproofing membrane comprises a carrier and pressure-sensitive adhesive (PSA) layers, an inorganic particle layer having particulate bodies which are partially embedded in the PSA and which have an average particle size less than the average thickness of the PSA layer, and an anti-submarining nano-silica-containing coating layer attached to un-embedded portions of the inorganic particles to prevent total embedding into the PSA when the membrane is rolled or unrolled, whereby water-tight seams are facilitated between overlapped portions of adjacently installed waterproofing membranes, and whereby the water-tight seam is achieved preferably using only detailing or waterproofing tape and without the additional use of a liquid primer, mastic, or other coating.

Various embodiments disclosed relate to a composite shingle. The composite shingle includes a particle layer and a polyketone layer proximate to the particle layer.

A roofing mat and a preparation method thereof are disclosed. A composite device includes a first roller, a second roller and a third roller. A die is located at the first roller. The preparation method comprises the following steps: step 1: laminating a first non-woven fabric to form a waterproof film; step 2: conveying asphalt to the die; step 3: rolling the first non-woven fabric by means of the first roller, rolling a woven fabric/a second non-woven fabric by means of the second roller, applying the asphalt to the waterproof film of the first non-woven fabric by means of the die, the first roller and the second roller being rolled and pressed against each other, the first non-woven fabric rolled by the first roller and the woven fabric/the second non-woven fabric rolled by the second roller being compressed together and then conveyed to a third roller for cooling, outputting, trimming, and winding.

Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.
