The aldehyde disinfectant is formaldehyde, polyoxymethylene, etc., among which the fumigation of formaldehyde is most commonly used.
The enclosed pens can be fumigated by adding 14 to 42 ml of formalin per 7 to 21 grams of potassium permanganate. When fumigation, the room temperature should not be lower than 15 ° C, the relative humidity should be 60% ~ 80%, you can add potassium permanganate in the container and then add formalin solution, closed doors and windows for more than 7 hours to reach For disinfection purposes, then open the doors and windows to ventilate and eliminate residual odor.
The disinfection effect of chlorine-containing disinfectants depends on the content of available chlorine. The higher the content, the stronger the disinfection ability, including inorganic chlorine and organic chlorine disinfectants. It can be sprayed on animal enclosures, cages, feeders and vehicles with 5% bleach solution for disinfection. Hypochlorous acid is rapidly disinfected and has no residue or odor, so it is often used for disinfection of food plants, meat plant equipment and countertops.
The alkali preparation mainly includes sodium hydroxide, etc., and the sodium hydroxide preparation for disinfection is mostly a crude alkali liquid containing 94% sodium hydroxide, and is often heated to prepare a 1% to 2% aqueous solution for disinfection by virus. The contaminated chicken house grounds, walls, playgrounds and dirt are also used for the disinfection of grounds such as slaughterhouses, food factories and transportation vehicles. Rinse with clean water after spraying for 6~12 hours.
The structure of the core barrel is generally divided into single - acting double core tube and most of the fishing apparatus. The double tube section consists of an outer tube assembly and an inner tube assembly. The outer pipe assembly includes; The main structure and working principle of the cartridge stopper, cartridge chamber, stable joint outer pipe, diamond reamer and diamond bit are as follows:
(1) Spear structure is composed of spear head and recovery spring. When coring, the fishing device is lowered to the upper part of the inner tube assembly in the drill pipe, and the fishing hook grasps the fishing spear, lifts the fishing device up, picks up the recycling card barrel, and inwardly compressing the cartridge card, so that the inner tube assembly and the outer tube are separated, so that the inner tube assembly is lifted up.
(2) The clip structure is mainly composed of the clip frame, clip, spring and other components. Its function is that when the inner tube sits on the outer tube, the clip expands with the help of the elastic force of the expansion spring and sticks to the inner wall of the clip chamber, so that the drilling tool can achieve positioning.
(3) Buffer structure by spring, locking mother, split pin composition. Protecting the inner tube when pulling the core.
(4) Single action structure is realized by two pairs of thrust bearings.
(5) Adjust the length of the inner pipe assembly and the outer pipe assembly of the structure, and fine-tune the lower shaft and the locking mother to achieve the gap required by the end of the spring seat and the step inside the drill bit.
(6) The fishing structure, also known as the fishing device, is mainly composed of fishing hook, hammer and safety rope. The fishing hook is used to hold the spearhead while fishing the inner pipe, and the weight is used to speed up the fishing device's descent to save fishing time. The safety rope is a thin rope. When the inner pipe is stuck for some reason and cannot be lifted, the safety rope can be forcefully lifted and then the drill can be lifted.
