镁水泥在天然养护条件下其体积是一个连续胀大进程，其线胀大率为0.1~0.2%，体积胀大率约为

Magnesium cement undergoes a continuous expansion process in volume under natural curing conditions, with a linear expansion rate of 0.1~0.2% and a volume expansion rate of approximately

菱镁矿在服烧进程中不可避免地发生部分过烧，使一部分MgO呈死烧状况，过烧的MgO水化进程很慢，当已构成强度的水泥石中的MgO再遇水进行水化时，生成Mg(OH)2，体积胀大

During the sintering process of magnesite, partial overburning is inevitable, resulting in a dead burning state of some MgO. The hydration process of overburned MgO is very slow. When MgO in the cement stone that has already formed strength is hydrated with water, it generates Mg (OH) 2, causing volume expansion

轻烧氧化镁中游离CaO水化时体积胀大90%，而卤片中存在着SO42-，当Ca(OH)2转化成石膏时，固体体积将增加2倍以上，导致制品变形，这也是束缚轻烧氧化镁中游离CaO含量卤片中SO42-含量的原因

During the hydration of free CaO in lightly burned magnesium oxide, the volume expands by 90%, while there is SO42- present in the brine sheet. When Ca (OH) 2 is converted into gypsum, the solid volume will increase by more than twice, causing deformation of the product. This is also the reason why the content of free CaO in lightly burned magnesium oxide is limited, and the content of SO42- in the brine sheet is limited

MgO-Mg-C12-H2O体系水化进程是一个激烈的放热反响进程，而出产的管道体积又大，若环境温度较高，则反响升温进程，板材本体温度过高，反响不充沛，构成较大的结晶应力和热胀大应力，使制品体积胀大。

The hydration process of MgO-Mg-C12-H2O system is an intense exothermic reaction process, and the volume of the produced pipeline is large. If the ambient temperature is high, it will reflect the heating process. If the temperature of the board body is too high, the response is not sufficient, forming a large crystallization stress and thermal expansion stress, causing the volume of the product to expand.

风管加工设备安排在修建物内时，应考虑修建物楼板梁的承载才干，需求时应采纳相应办法。关于洁净体系的风管制造应有洁净封闭仓库贮存制品或半制品。

When arranging the air duct processing equipment inside the building, the load-bearing capacity of the building's floor beams should be considered, and corresponding methods should be adopted when needed. The manufacturing of air ducts for clean systems should have clean enclosed warehouses for storing products or semi-finished products.

风管加工场所应预留现场资料制品以及半制品的运送通道，风管加工场所的挑选不得阻挠消防通道。大样图体系图经审查契合要求，并进行了技能及交底。

The air duct processing site should reserve transportation channels for on-site data products and semi-finished products, and the selection of air duct processing sites should not obstruct fire exits. The detailed system diagram has been reviewed and found to meet the requirements, and skills and disclosures have been made.

风管加作业业地址应有安放施工机具和资料堆积场所，设备和电源应有牢靠的防护设备。作业场所路途应疏通。需求有能满意消防要求的各种器械及设备。

There should be a place for construction equipment and data storage in the air duct and operation site, and the equipment and power supply should have reliable protective equipment. The route to the workplace should be cleared. We need various instruments and equipment that can meet the fire protection requirements.

风管预制应有独立的作业场所，场所应平坦清洗，加工途径应找平。双面铝箔绝热板风管等其他复合资料风管的场所应单调，应有满意的制品堆积场所。

The prefabrication of air ducts should have an independent workplace, which should be flat and cleaned, and the processing path should be leveled. The location of double-sided aluminum foil insulation board air ducts and other composite material air ducts should be monotonous, and there should be a satisfactory place for product stacking.
