The invention discloses a sound insulation and heat insulation pad of an automobile. A production process of the sound insulation and heat insulation pad of the automobile includes the steps that a base material is heated at high temperature through a two-stage oven, hot-melting felt is heated at high temperature through a one-stage oven, the heated base material and the heated hot-melting felt are continuously put into a mould to be subjected to compression moulding forming together, meanwhile, punching of part of holes is completed, and then a semi-finished product is obtained, wherein the high temperature is 280-380 DEG C; the semi-finished product is cut through a water jet cutter to form the needed product. Production efficiency is improved, the fund input of mould equipment is lowered, product stability and uniformity are improved, safety and environmental friendliness are achieved as no solvent adhesive is used, the rejection rate and production cost are lowered, and the sound absorption, sound insulation and heat insulation properties are excellent.

The invention discloses a manufacturing process of gauze with high flexibility. The manufacturing process, which has managed to simplify technical procedures, improve production efficiency and decrease environmental pollution on the premise of producing gauze with high flexibility, comprises preparation of raw material for dyed yarn, enhancement of flexibility, weaving, napping, sizing and packaging .

The invention discloses a multi-layer structure sound-insulating carpet and a preparation method thereof. The sound-insulating carpet separates the inner wall of an automobile compartment from the space of the automobile compartment; the sound-insulating carpet is arranged on the inner wall of the automobile compartment at prescribed intervals; the sound-insulating carpet It has a sound insulation part; the sound insulation part is arranged between the sound insulation carpet and the inner wall of the car compartment; the sound insulation part has a transmission favorable part and a transmission unfavorable part, and the transmission favorable part is a favorable part for the transmission of outside noise, And the transmission favorable part surrounds the periphery of the transmission unfavorable part, and the transmission favorable part is more favorable for the transmission than the unfavorable part; the noise transmission is suppressed from the transmission mode by the sound insulation member, thereby suppressing the transmission of the noise to the vehicle compartment. ; The sound insulation carpet installed in the way of ensuring the normal use of materials, through the combination of dispersion and extension, weakens the energy of the sound in the transmission, enhances the acoustic impedance, and has higher sound insulation.

The invention provides a gynecological clinical leucorrhea sampling, storing and inspecting device, and relates to the technical field of medical apparatuses and instruments. The interior of the sampling main body is hollow, and the sampling drawing and inserting rod is connected to the interior of the sampling main body; the number of the sampling cotton swabs is four, the four sampling cotton swabs are located in the sampling main body in a surrounding mode, and the sampling cotton swabs are connected with the sampling drawing and inserting rod; the movable rod is connected to the top end of the sampling drawing and inserting rod. The four sampling cotton swabs synchronously perform sampling operation, enough leucorrhea detection samples are sampled at a time, discomfort of a patient caused by repeated sampling is avoided, the leucorrhea samples are stored in the sampling main body after sampling is completed, and the leucorrhea samples are prevented from being externally polluted when pulled out. The problems that according to a traditional leucorrhea sampling and inspection device, enough leucorrhea samples are difficult to sample at a time, medical workers need to operate for multiple times, the overall consumed time is long, and discomfort is likely to be caused to a patient are solved.

The invention discloses a cultivation device and a method for increasing the survival rate of seedlings, and relates to the technical field of cultivation devices, in order to solve the problem that the cultivation devices currently on the market cannot provide different planting schemes for different plant species during planting, so as to make the cultivation method more accurate. The problem of low survival rate of plants grown by uninformed users. A cover plate is fixedly arranged at the middle position of the upper end of the casing, four support seats are arranged in sequence at the lower end of the inside of the casing, a sensor box is arranged at the middle position of the support seat, and a sensor box is arranged above the support seat There is a flowerpot, a control unit is installed on the inner wall of one side of the casing, a loosening mechanism is movably installed above the cover plate, and a first electric telescopic rod is fixedly arranged between the adjacent flowerpots. A shading mechanism is fixed above the electric telescopic rod, and the cultivation control system includes a variety identification system, a plant state analysis system, a planting depth system and a control induction system.
