The invention discloses an iodoform-epoxy resin embedding preparation method for SEM-EDS analysis of a coalbed methane reservoir sample, and relates to the technical field of reservoir sample detection. The method comprises the following steps: cutting, cleaning and performing low-temperature vacuum drying on a coalbed methane reservoir sample; adding iodoform into the epoxy resin, and fully stirring until the iodoform is completely dissolved to form a uniform and clear mixed solution; then adding a curing agent and stirring at a low speed; after natural and vacuum combined defoaming, embedding and curing the sample; and finally, a flat observation surface is obtained through step-by-step mechanical polishing and argon ion polishing, and sample preparation is completed after conductive treatment. According to the method, iodoform is dissolved firstly, and then the curing agent is added, so that iodoform crystal agglomeration and bubble introduction are effectively avoided, the contrast of the backscattered electron image is remarkably improved, the primary pores and cleat structures of the coal rock are protected, and the EDS quantitative analysis precision is improved; the method is simple in process, controllable in process parameter, good in repeatability, suitable for various samples such as coal rock, coal-containing clastic rock and coal seam dirt band, and capable of providing high-quality sample preparation guarantee for coal bed gas reservoir microcosmic characterization.

A method of manufacturing a halogenated polyolefin comprising: - halogenating a polyolefin in a reaction chamber of an extruder-reactor, notably a reaction chamber kept under nitrogen atmosphere, by reacting the polyolefin with a halogenating agent in the presence of an activator, wherein the halogenating agent comprises iodoform (HCI3) and the activator comprises sodium hydroxide (NaOH).

According to the deciduous tooth root canal filling paste and the preparation method, iodoform, metronidazole, ZnO and Ca (OH) 2 are adopted as main components, the components have a wide application basis in the field of oral medicine and are high in safety and good in biocompatibility, and it can be ensured that the performance of the paste is stable and reliable by accurately controlling the proportion of all the components; iodoform and metronidazole are used as main components of the paste, have a remarkable antibacterial effect and can effectively kill bacteria in root canals, reduce infection risks and create a sterile environment for healing of periapical tissues, and due to the antibacterial effect, the success rate of root canal treatment is increased, the treatment cycle is shortened, and the treatment cost is reduced. The number of times of re-consultation and pain of the patient are reduced; znO and Ca (OH) 2 have excellent biocompatibility and cannot stimulate or damage periapical tissues, so that the safety of a treatment process and the comfort of a patient are guaranteed, and meanwhile, the components can also promote regeneration and repair of the periapical tissues.
