輕質(zhì)石膏和重質(zhì)石膏的區(qū)別有哪些脸侥?

重質(zhì)石膏和輕質(zhì)石膏兩者骨料不一樣有送,重質(zhì)石膏骨料是沙子,輕質(zhì)石膏是怖嬷荩化微珠夫凭。苍古化微珠作輕質(zhì)填充骨料有絕熱扭妖、防火环起、吸音等優(yōu)點荡明。在建材行業(yè)中,用材锢化微珠作為輕質(zhì)骨料尊勿,可提高砂漿的和易流動性和自抗強度,減少材性收縮率畜侦,提高產(chǎn)品綜合性能,降低綜合生產(chǎn)成本躯保。同時残牛化微珠相較沙子還可以因為表面玻化形成一定的顆粒強度途事,而具有耐老化耐候性強和優(yōu)異的絕熱验懊、防火、吸音等性能尸变。石膏含量不同輕質(zhì)抹灰石膏要求石膏粉含量≥75%义图,重質(zhì)抹灰石膏要求石膏粉含量≥35%。技術(shù)性能不同1召烂、密度不同碱工;輕質(zhì)抹灰石膏密度≤1000kg/m3,重質(zhì)抹灰石膏密度>1000kg/m3奏夫。

The aggregates of heavy gypsum and light gypsum are different, with heavy gypsum aggregates being sand and light gypsum being vitrified microspheres. Vitrified microspheres as lightweight filling aggregates have advantages such as insulation, fire resistance, and sound absorption. In the building materials industry, using vitrified microspheres as lightweight aggregates can improve the flowability and self resistance of mortar, reduce material shrinkage, improve product comprehensive performance, and reduce comprehensive production costs. At the same time, compared to sand, vitrified microspheres can also form certain particle strength due to surface vitrification, and have strong aging and weather resistance, as well as excellent insulation, fire prevention, and sound absorption properties. The gypsum content is different. Light plaster gypsum requires a gypsum powder content of ≥ 75%, while heavy plaster gypsum requires a gypsum powder content of ≥ 35%. Different technical performance: 1. Different density; The density of lightweight plastering gypsum is ≤ 1000kg/m3, and the density of heavy plastering gypsum is>1000kg/m3.

2怕篷、保水率(%);輕質(zhì)抹灰石膏保水率≥ 60%艳杯,重質(zhì)抹灰石膏保水率≥ 75%憎唯。
2. Water retention rate (%); The water retention rate of lightweight plastering gypsum is ≥ 60%, and that of heavy plastering gypsum is ≥ 75%.
3、拉伸粘結(jié)強度统褂;輕質(zhì)抹灰石膏拉伸粘結(jié)強度≥0.3Mpa筛粘,重質(zhì)抹灰石膏拉伸粘結(jié)強度≥0.4Mpa。
3. Tensile bonding strength; The tensile bonding strength of lightweight plastering gypsum is ≥ 0.3Mpa, and the tensile bonding strength of heavy plastering gypsum is ≥ 0.4Mpa.
4稼掏、抗壓強度熊倡;輕質(zhì)抹灰石膏抗壓強度≥1.5Mpa,重質(zhì)抹灰石膏抗壓強度≥4.0Mpa叨连。
4. Compressive strength; The compressive strength of lightweight plastering gypsum is ≥ 1.5Mpa, and the compressive strength of heavy plastering gypsum is ≥ 4.0Mpa.
5蚓橡、抗折強度;輕質(zhì)抹灰石膏抗折強度≥1.0Mpa矛唤,重質(zhì)抹灰石膏抗折強度≥2.0Mpa抠佩。輕質(zhì)抹灰石膏,具有容重小怜腊,施工便捷肺然,好運輸蔫缸,遇水不化,成本低际起,保溫性能優(yōu)良拾碌,強度適中,能夠機械噴涂等種種特點街望,是淘汰重質(zhì)粉刷石膏后的又一升級換代產(chǎn)品校翔。給開發(fā)商和施工單位帶來了福音,給住戶帶來了更加舒適的環(huán)境灾前。輕質(zhì)抹灰石膏與市場上相比防症,每噸可出面積130㎡/公分,是重質(zhì)粉刷石膏的3倍哎甲,大大提高了施工的效率和運輸成本蔫敲。
5. Bending strength; The flexural strength of lightweight plastering gypsum is ≥ 1.0Mpa, and the flexural strength of heavy plastering gypsum is ≥ 2.0Mpa. Lightweight plastering gypsum has various characteristics such as small bulk density, convenient construction, easy transportation, low cost, excellent insulation performance, moderate strength, and mechanical spraying. It is another upgraded product after the elimination of heavy plastering gypsum. Bringing good news to developers and construction units, and bringing a more comfortable environment to residents. Compared with the market, lightweight plastering gypsum can produce an area of 130 square meters per ton, which is three times that of heavy plastering gypsum, greatly improving construction efficiency and transportation costs.
