Rectal piezometric tube

Abstract

The invention discloses a rectal piezometric tube. The raw materials of the rectal piezometric tube are composed of: HDPE: 28-35 parts; corn starch: 3-6 parts; viscosity reducer: 2-6 parts; polyvinyl chloride: 80‑88 parts; Butylated melamine formaldehyde resin: 14‑20 parts; Triallyl isocyanate: 12‑18 parts; Stabilizer: 1‑2 parts; LLDPE: 35‑45 parts; Ethyl acetate: 12‑18 parts; BPO: 5‑9 parts; acrylic acid: 21‑25 parts; thiourea: 2‑4 parts; polyvinyl alcohol: 15‑20 parts; The invention provides a rectal pressure measuring tube, which has the advantages of improved flexibility, easy bending, good strength, large drainage, and can be developed under X-ray and B-ultrasound.

Description

technical field [0001] The invention relates to a rectal pressure measuring tube. Background technique [0002] Since the output of China's plastic film accounts for about 20% of the total output of plastic products, it is one of the fastest growing categories of plastic products. From the application field of China's plastic film (thickness 0.06mm ~ 0.26mm), the packaging industry has the largest consumption, the most varieties and the widest application, and its consumption accounts for about 2 / 3, followed by agriculture accounting for about 30%. Then there are functional membranes, such as microporous membranes, shielding membranes, geomembranes, etc. If appropriate plastic additives are added to the resin matrix, various functional films required can be prepared. The production methods in the plastic film industry include calendering and extrusion. The extrusion method is divided into extrusion film blowing, extrusion casting, extrusion stretching (also known as second...
