The invention provides an automobile trim material combined with a non-woven fabric and a woven fabric The automobile trim material is prepared by virtue of the following steps: 1, cutting ramie into 70mm fibers, putting the fibers into a stainless steel vessel, adding a sodium bicarbonate solution and stirring for 60 minutes; 2, cleaning jute fibers and drying the jute fibers; 3, adding warm water at a temperature of 30 DEG C, performing constant-temperature bath for 60 minutes, adding 1% constant temperature bath and 0.1% ceric ammonium nitrate, cleaning, and then drying; 4, putting the jute fibers on fur machine equipment, and performing shredding mixing on the jute fibers and polypropylene fibers; 5, carding the fibers into a net shape by use of a carding machine; 6, paving the fibers to form a multilayer net body with weight per square meter of 1500g; 7, paving polypropylene fabrics on both sides as surface layers, and performing reciprocating reinforcement by use of a needling machine; and 8, pressing to prepare an automobile trim material sectional material by use of die pressing equipment. The automobile trim material produced by the method is low in price, is capable of adsorbing sound and insulating heat, is high in rigidity, durable in use, simple in technological process and free from environmental pollution.

The invention discloses a breeding method for young chickens. The method comprises controlling the breeding density to 35 to 45chickens per square meter; in the first week, the temperature of the brooding room was controlled at 33 to 35 DEG C, and then decreased by 1 to 1.2 DEG C per day until the temperature reaches 25 to 27 DEG C, the temperature is then controlled within this range; humidity iscontrolled at 65% to 75%; in the first week, the ordinary fluorescent lamp is used for irradiating for 25 to 28 hours, and then the irradiation is reduced by 1 to 1.5 hours per day until the daily illumination time is 20 to 22 hours. The culture management technology of the invention conforms to the growth rule of the chicken, is scientific and reasonable, the survival rate of the chicken is high, and the growth condition is good; in addition to soybeans and corn as the basic feed, acanthopanax senticosus, astragalus, honeysuckle, isatis root and honey are also added to the chicken food. It has the functions of antibacterial and anti-inflammatory, improving immunity, strengthening the spleen and stomach, promoting digestion, strengthening bones and other functions, preventing the occurrence of chicken diseases and promoting the growth of chickens. Chicks have a high survival rate of 95%, good growth, strong and active.

The invention discloses a heat-insulating structure at the top of an open-air atmospheric storage tank, which comprises a tank top cap (1) and has the structural characteristics that hook nails (2) and a heat-insulating layer (3) are arranged on the tank top cap (1), a wire mesh (4) is arranged outside the heat-insulating layer (3), and a plastering protection layer (5) is arranged on the surfaces of the heat-insulating layer (3) and the wire mesh (4). One hook nail (2) is arranged per square meter, and each hook nail (2) is made of a galvanized wire of which the diameter is phi4mm; each hook nail (2) is exposed for 5cm-6cm on the surface of the heat-insulating layer (3); the wire mesh (4) is a galvanized wire mesh, and the wire diameter is phi1.6mm; and the wire mesh (4) is in a hexagonal or slipknot rhombic structure. The invention enables the plastering protection layer to not only keep the original advantages but also well overcome the original defects to enhance the bearing strength of the plastering protection layer, thereby preventing the plastering protection layer from being torn and leaking water due to frequent stress and overlarge deformation, and achieving the effects of durable protection, safety and stability.
