  • Publication number: 20200088469
    Abstract: A foaming heating system includes a furnace, a conveying device, a heating device and a plurality of detectors. The furnace has a furnace body, a heating channel and ventilation holes. The conveying device transports foam material passing through the heating channel. The heating device has a heater, a heating tube, a temperature regulator and at least one temperature adjustment pipeline. The plurality of detectors detects the temperature of each section of the heating channel. When a temperature abnormality of a certain section is detected, the temperature of the certain section is adjusted by the at least one temperature adjustment pipeline.

  • Publication number: 20170130021
    Abstract: A formamide-free foam prepared by using sodium bicarbonate as a foaming agent and electron-beam irradiation for crosslinking is revealed. After copolymer and sodium bicarbonate being mixed evenly, the mixture is heated and compounded to form an intermediate. Then the intermediate is pressed and injected to form a sheet. Next the intermediate is irradiated by an electron-beam to form crosslinks therein. At last the intermediate is heated and foamed to get a formamide-free foam. Compared with foam produced by using azodicarbonamide as the foaming agent available now, formamide-free foam not only causes no harm to human health but also gives no negative effect to the environment during recycling. Thus the formamide-free foam is really environmentally friendly.

  • Publication number: 20170081471
    Abstract: A polyamide capable of being deeply dyed and a method for preparing the same are revealed. The main material for polyamide is caprolactam. Amino groups are added to react during ring opening of caprolactam. Then polymerization is carried out to get polyamide in granular form or polyamide is made into fibers directly. The granules or fibers of polyamide prepared are not only capable of being deeply dyed, but also with lower dyeing temperature and better color fastness. Moreover, less time is required for dyeing and finishing processes due to simple manufacturing processes and fewer parameters involved. Thus the production cost is significantly reduced.

  • Publication number: 20160272755
    Abstract: A polyester polymer and a method for manufacturing the same are revealed. Sulfonate groups (—SO3) are used for modification of polyethylene terephthalate (PET) and chemical extrusion technique is used in modification processes. The physiochemical properties of PET sulfonate obtained including moisture absorption, secondary transition temperature, melting point etc. are improved significantly. Thus the dyeing process can be carried out at lower temperature and the dyeing depth is improved. The purpose of energy saving and reduced carbon dioxide emission are further achieved.

  • Patent number: 9073285
    Abstract: A foam base with a connection structure includes the foam base and a connection member. The connection member includes an adhesive connection portion and a folding portion. The adhesive connection portion is adhered to the foam base so that the connection member is fixed on the foam base. The folding portion is used to connect another adjacent foam base. Before connection, the folding portion is folded and only has a portion extending out of the foam base for transportation and storage.
