The disclosure describes an airtight cooler box having a base panel, a collapsible unitary side panel, and a top panel. The base panel extends orthogonally from the base to form an opening defined by side panel top edges. A top panel having pouches on an inside surface is sized fit the top opening. A rigid base plate rests on a base panel inside surface. A top plate with vent openings is located inside the container under the top panel. Zippered closures on three top edges of the side panel and corresponding top panel three edges close the box. Box inner and outer surfaces include a poly-vinyl chloride material bonded to an aluminum laminate with multiple layers of foam interposed between panel inner and outer surfaces.

The invention relates to a pulverized coal ash and PVC (Poly Vinyl Chloride) composited micro-foaming building template reinforced by long glass fibers. The building template comprises a PVC composited modified material matrix, and the matrix consists of PVC, a heat stabilizer, a foaming agent, a foam stabilizer, a flexibilizer, an internal lubricant, an external lubricant, pulverized coal ash and high-strength long glass fibers. According to the pulverized coal ash and PVC (Poly Vinyl Chloride) composited micro-foaming building template reinforced by long glass fibers as well as a preparation method of the building template, the pulverized coal ash and the long glass fibers are adopted for filling and reinforcement, so that both the dimensional stability and the economical efficiency of the building template are enhanced greatly; the pulverized coal ash as a recyclable raw material is environment-friendly and energy-saving and can be used for replacing inorganic fillers such as calcium carbonate, so that the economic cost is lowered; in addition, the building template has advantages of light weight, resistance to medium acid-alkali corrosion, recyclability, heat insulation, good mechanical performance, flame retardation, wear resistance and the like; besides, the micro-foaming building template, which is manufactured by virtue of specific auxiliaries and an advanced micro-foaming technology, is environment-friendly, nontoxic, light in weight and resistant to medium acid-alkali corrosion; the service cycle of the building template is prolonged by 4-5 times than that of a wooden template and a bamboo-glue template, and the physical and mechanical properties of the building template are enhanced by 3-4 times; in addition, the building template can be demolded easily, and simultaneously the building template is recyclable, green and environment-friendly and saves the economic cost.

The invention discloses a leakage detection device of large soft transfusion package bags or soft bottles, and relates to the technical field of pharmaceutical packaging machinery. The leakage detection device is composed of a rack (4), a programming logic controller (3), a vertical beam (19), a horizontal beam (22), an extrusion fixed plate (17), a fixture (23), a recycling bin (2), a motor (32) with a brake and a deceleration component, and a leakage detection component. The device has the characteristics of high detection precision, low working intensity, safety and reliability and the like, is suitable for the leakage detection of non-PVC (poly vinyl chloride) film large soft transfusion package bags in various specifications or PP large soft transfusion bottles in various specifications, and can be suitable for the leakage detection of large soft transfusion package bags or soft bottles in various specifications, which are made of other materials.

The invention relates to an acrylic impact modifier having a core-shell structure that provides an acrylic impact modifier composition comprising (a) a rubber core containing an alkyl acrylate polymer comprising at least two layers having different cross-linking densities, and (b) a shell containing an alkyl methacrylate polymer; to a process for the preparation of the acrylic impact modifier; and to a poly(vinyl chloride) composition comprising it. The acrylic impact modifier imparting excellent impact resistance was invented by employing multi-stage polymerization and at the same time by controlling the swelling index of rubber particles by changing the degree of cross-linking from stage to stage. And the poly(vinyl chloride) comprising the impact modifier of the present invention has good weatherability as well as excellent impact strength.

An airtight cover assembly includes a side panel folded around goods on a pallet presenting top and bottom opening, a top panel with a plurality of pouches positioned on an inside surface above a vented rigid plate, and a bottom panel encloses the pallet. Hook and loop closures secure the panel assembly. Panel inner and outer surfaces of a poly-vinyl chloride material bonded to an aluminum laminate enclose multiple layers of foam.

The invention relates to a PVC (Poly Vinyl Chloride) profile added with a chloroethylene-acrylate copolymer resin and a preparation method thereof, and belongs to the technical application of the chloroethylene-acrylate copolymer resin in PVC resin processing. According to the invention, the common PVC resin is modified by using the special properties of the chloroethylene-acrylate copolymer resin such as internal plasticization property, excellent processability and tenacity; the processing formulation by weight is as follows: 100 parts of PVC resin, 5-10 parts of chloroethylene-acrylate copolymer resin, 1-5 parts of heat stabilizer, 5-20 parts of filler and 3-6 parts of other additives. In the processing process of the PVC profile, the chloroethylene-acrylate copolymer resin is used for substituting for processing modifiers ACR (Acrylic Rubber) and CPE (Chlorinated Polyethylene), and a specific mixing process is adopted so as to achieve the synergistic effect of the chloroethylene-acrylate copolymer resin with inorganic particles, and consequently, the processing temperature of the PVC profile is reduced and the mechanical properties of the PVC profile are improved.

The invention relates to automatic accurate cutting equipment of a PVC (Poly Vinyl Chloride) wired hose. The equipment comprises a baseplate, wherein a support device, a tension device, an auxiliary device, a driving device and a shearing device are sequentially arranged on the baseplate from back to front and are cooperated to complete the automatic accurate cutting of the PVC wired hose. By means of the equipment disclosed by the invention, the problems that in a conventional PVC wired hose shearing process, cuts are uneven during manual shearing process of the PVC wired hose, error exists during the manual measurement process of the PVC wired hose, the using effect of the PVC wired hose is influenced, the PVC wired hose is easily deformed during manual tensioning process, the manual shearing of the PVC wired hose is high in the labor intensity and low in the working efficiency and is not suitable for batch operation and the like can be solved; and the function of automatically and accurately cutting the PVC wired hose can be realized.
