鎂水泥在天然養(yǎng)護(hù)條件下其體積是一個連續(xù)脹大進(jìn)程,其線脹大率為0.1~0.2%,體積脹大率約為
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
菱鎂礦在服燒進(jìn)程中不可避免地發(fā)生部分過燒,使一部分MgO呈死燒狀況,過燒的MgO水化進(jìn)程很慢,當(dāng)已構(gòu)成強(qiáng)度的水泥石中的MgO再遇水進(jìn)行水化時,生成Mg(OH)2,體積脹大
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
輕燒氧化鎂中游離CaO水化時體積脹大90%,而鹵片中存在著SO42-,當(dāng)Ca(OH)2轉(zhuǎn)化成石膏時,固體體積將增加2倍以上,導(dǎo)致制品變形,這也是束縛輕燒氧化鎂中游離CaO含量鹵片中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體系水化進(jìn)程是一個激烈的放熱反響進(jìn)程,而出產(chǎn)的管道體積又大,若環(huán)境溫度較高,則反響升溫進(jìn)程,板材本體溫度過高,反響不充沛,構(gòu)成較大的結(jié)晶應(yīng)力和熱脹大應(yīng)力,使制品體積脹大。
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.
風(fēng)管加工設(shè)備安排在修建物內(nèi)時,應(yīng)考慮修建物樓板梁的承載才干,需求時應(yīng)采納相應(yīng)辦法。關(guān)于潔凈體系的風(fēng)管制造應(yīng)有潔凈封閉倉庫貯存制品或半制品。
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.
風(fēng)管加工場所應(yīng)預(yù)留現(xiàn)場資料制品以及半制品的運(yùn)送通道,風(fēng)管加工場所的挑選不得阻撓消防通道。大樣圖體系圖經(jīng)審查契合要求,并進(jìn)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.
風(fēng)管加作業(yè)業(yè)地址應(yīng)有安放施工機(jī)具和資料堆積場所,設(shè)備和電源應(yīng)有牢靠的防護(hù)設(shè)備。作業(yè)場所路途應(yīng)疏通。需求有能滿意消防要求的各種器械及設(shè)備。
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.
風(fēng)管預(yù)制應(yīng)有獨(dú)立的作業(yè)場所,場所應(yīng)平坦清洗,加工途徑應(yīng)找平。雙面鋁箔絕熱板風(fēng)管等其他復(fù)合資料風(fēng)管的場所應(yīng)單調(diào),應(yīng)有滿意的制品堆積場所。
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.
