HiQLCD v1.5.0

Chemicals

HiQLCD v1.5.0 completes the chemicals category expansion, adding and optimizing 150+ chemical entries covering basic chemicals, inorganic salts, acids and alkalis, industrial gases, lubricants, plastics and additives, metallurgical materials, battery materials, and fine chemicals. This release adds entries for plastics, rubber and processing additives, basic chemical products such as sodium hypochlorite, sodium bicarbonate, lithium chloride, industrial titanium dioxide, urea, phosphoric acid, and industrial gases including nitrogen, argon, CO2, helium, and CO. Sulfuric acid datasets were specifically optimized and liquid oxygen datasets updated to better reflect current production levels in China.

Steel and Non-ferrous Metals

HiQLCD v1.5.0 completes the steel and non-ferrous metals category update, adding and optimizing 100+ material and process datasets, covering non-ferrous metal mining and beneficiation, heavy and light non-ferrous smelting, steelmaking, precious/rare metal recycling, and metal processing. This release adds copper, lead, zinc, tin, nickel, antimony, tungsten, molybdenum, titanium, magnesium, manganese, gold, and silver-related ore, concentrate, intermediate and final metal products. Steel category additions include direct reduced iron, cast iron, ESP endless-rolled hot-rolled coil, seamless steel pipe, brass, and Al-Ti-B wire. Precious metals recycling adds silver ingot, gold ingot, lead anode slime, gold-loaded carbon, tellurium powder, etc., covering pyrometallurgical/hydrometallurgical pressure leaching, cyanide leaching, and halogen leaching routes.

Electrical Equipment

HiQLCD v1.5.0 adds 35+ electrical equipment entries, covering towers and supports, overhead lines, instrument transformers, surge arresters, circuit breakers, power transformers and reactors, insulators and fittings, lightning protection, reactive compensation, and metering. New entries include angle steel towers, steel tubular towers and poles, concrete poles, ACSR conductors and OPGW ground wires, current and voltage transformers covering mainstream insulation media and structures, as well as surge arresters, circuit breakers, insulators, suspension clamps, lightning rods, power transformers, capacitors, and smart electricity meters.

Transportation

HiQLCD v1.5.0 adds 29 road freight datasets, mainly covering gasoline-fueled road freight trucks, spanning multiple specifications (mini, light, medium, heavy Ⅰ/Ⅱ/Ⅲ) and emission standards (China III to China VI). Datasets with unspecified load capacity or unspecified emission grade are also available for flexible modeling.

Water Supply and Drainage

HiQLCD v1.5.0 adds 136 water supply datasets covering waterworks construction, conventional treatment, advanced treatment, technology mixes and pipeline distribution, filling gaps in water supply industry coverage. It also adds 75 sewage pipeline construction datasets covering urban and rural areas, providing a basis for refined modeling of wastewater treatment.

Waste Treatment and Recycling

HiQLCD v1.5.0 expanded waste treatment and recycling categories and improved selected material recycling chains (glass, copper, rubber, aluminum, etc.). Municipal solid waste and domestic wastewater treatment now cover city-level regions, with new market-type datasets for municipal solid waste treatment, and known issues fixed.
