drilled metal sheetWith the development of mining industry, the classification of pig iron is already very broad in our country, which can satisfy the demand of mechanical industry. In general, the iron used to produce large rolls of galvanized wire can be divided into two classes. A metal exercised directly from the iron ore through the iron making stroke, the composition of the ore is iron oxide, silica and other miscellaneous stones. When this ore is specially refined into metal iron, carbon, silicon, manganese, and other elements are mixed into it. The material produced in this way is called ordinary pig iron, which is also the material for the first grade.

Its ability to dissolve in water also makes it a preferred ingredient in liquid medications and suspensions.
- Additionally, these polymers are used in the production of adhesives and sealants, where they impart superior bonding strength and flexibility
Answer: For putty powder applications, a viscosity of 100,000 is sufficient, but good water retention is important. For mortar applications, higher viscosity is required, preferably around 150,000. For adhesive applications, quick-dissolving products with high viscosity are needed.
- Hydroxyethyl cellulose (HEC), a derivative of cellulose, is a nonionic, water-soluble polymer that has gained significant attention in various industries due to its unique properties and versatility. With the chemical formula (C6H10O5)n.n(C2H4(OH)2), HEC is synthesized by the ethoxylation of cellulose, a natural polymer found abundantly in plant cell walls.

- How to Choose the Right HPMC?
- When handling HPMC, personal protective equipment (PPE) such as gloves and masks should be worn to avoid inhalation or skin contact. Although HPMC is considered non-toxic, prolonged exposure can lead to irritation of the respiratory tract or skin. Therefore, working in well-ventilated areas and minimizing direct contact is essential.
- The concentration of HPMC also influences the gelation temperature. As the concentration of HPMC increases, the number of polymer chains in the solution increases, leading to stronger interactions between the chains and a higher gelation temperature As the concentration of HPMC increases, the number of polymer chains in the solution increases, leading to stronger interactions between the chains and a higher gelation temperature

Data on chronic toxicity and carcinogenicity are available for microcrystalline cellulose (E 460), methyl cellulose (E 461) hydroxypropyl cellulose (E 463), HPMC (E 464) and sodium carboxymethyl cellulose (E 466). Some studies were unfit for evaluation due to methodological shortcomings. In the only relevant study, the dietary administration of even high doses of microcrystalline cellulose (E 460) (30%, 15,000 mg/kg bw) to rats for 72 weeks did not affect survival, feed efficiency or haematology. Apart from some dystrophic calcification in renal tubules, no other relevant lesions were noted and tumour incidence did not differ with that of controls. Several studies were conducted in rats with methyl cellulose (E 461) via feed or drinking water or by gavage at concentrations up to 5% (2,500 mg methyl cellulose/kg bw per day) and for up to 2 years. For all examined parameters, no adverse effects were reported and also the observed tumours did not differ in type and number in treated and control groups. In the only identified study, the daily dosing of male and female rats (0, 1,500, 3,000 or 6,000 mg hydroxypropyl cellulose/kg bw) via gavage for 6 months did not cause adverse effects (including carcinogenicity) apart from a decrease in body weight in high-dosed rats (statistically significant in females only). Apart from a decrease in body weights of high-dosed males, no other significant adverse findings were reported and there was no indication of a carcinogenic effect in rats of either sex dietary exposed to HPMC (E 464) up to 20% (10,000 mg/kg bw per day) for 1 year. Carboxy methylcellulose (E 466) was tested in mice and rats at dosages of 0, 10,000 or 100,000 mg/kg diet (equivalent to 0, 1,500 or 15,000 mg/kg bw per day for mice and to 0, 500 or 5,000 mg/kg bw per day for rats) for up to 104 weeks. Despite the increase in feed intake, a treatment related decrease in body weight was noted at the end of the treatment. Histological examination revealed no intestinal abnormality or evidence of the passage of the additive across the intestinal wall in either species and the tumour incidences were comparable among groups.
