石膏板

01 · 材料构成与产品定位 / Material & Positioning

纸面石膏板是以建筑石膏粉（半水硫酸钙）为主要原料，上下两面覆以专用护面纸，加水调浆、成型凝固、干燥制成的轻质板材，俗称“三明治”结构。芯材为无机材料，质轻、防火（石膏结晶水）、隔声、保温、可钉可锯可刨可粘贴，施工以干作业为主，广泛用于内隔墙、吊顶、贴面墙和防火分区。

Paper-faced gypsum board is a lightweight panel made from calcined gypsum (calcium sulphate hemihydrate) as the main raw material, faced on both sides with dedicated liner paper, mixed with water, formed, set and dried — the familiar “sandwich”. The core is inorganic: light, fire-inhibiting through its water of crystallisation, sound- and heat-insulating, and easy to nail, saw, plane or bond. Dry construction suits interior partitions, ceilings, lining walls and fire compartments.

颜色只是识别方式：资料以浅灰/灰白面作普通板、粉红面作耐火板、绿色面作耐潮/耐水板的区分。颜色本身不代表性能等级，采购时应以板型、芯材配方和对应检测报告为准，不能只凭纸面颜色判断。Colour is identification only: the material uses light grey for regular, pink for fire-related and green for moisture/water-related boards. Colour does not itself establish a performance grade — confirm board type, core formulation and test evidence.

芯材不可燃与“整板燃烧性能”“墙体系统耐火极限”是三件不同的事。板材反应分级、表面燃烧性能和构件耐火等级都应绑定对应型号与完整构造的测试结果。A non-combustible core, a board's reaction-to-fire classification and an assembly's fire-resistance rating are three different things. Each must be tied to the tested model and full construction.

面纸颜色仅为系列识别参考，不可代替型号标签或检测报告。 / Facing colour is not evidence of performance.

02 · 原料对照：脱硫石膏 vs 磷石膏 / FGD Gypsum vs Phosphogypsum

同一“石膏板”可使用不同来源的石膏原料，原料路线会影响纯度、杂质、颜色和稳定性。以下对照来自产品资料，属资料口径；具体批次的纯度、放射性核素、重金属和强度应以供应商检测报告为依据，不把品类名称当成合格证明。

The same “gypsum board” may use feedstock from different sources, which affects purity, impurities, colour and consistency. The comparison below follows the product material; batch-specific purity, radionuclides, heavy metals and strength require supplier test reports, and a feedstock name is not proof of compliance.

资料另附有板芯实拍对比图（磷石膏芯偏灰、密度略差；脱硫石膏芯白净细腻），本页不引用非 WebP 原图。现场“滴水测试”——切开板边滴水观察是否吸水——只作直观演示，不能替代实验室吸水率检测；也不能据“是否立即吸水”单独判定整批原料来源。对外介绍“脱硫石膏原料、放射性达标、强度稳定”时，应同时出示对应批次的检测报告与执行标准编号。The material also includes a core photo comparison (phosphogypsum core greyer and less dense; FGD core whiter and finer); this page does not reference the non-WebP source images. The on-site “water-drop” demo is only indicative and cannot replace laboratory water-absorption testing, nor identify a batch's feedstock by itself. Claims of FGD feedstock, compliant radioactivity and stable strength must be accompanied by the matching batch report and standard number.

外观对照不能单独证明原料来源、密度或合格等级。 / Appearance alone cannot establish material origin, density or compliance.

03 · 八步生产工艺 / Eight Production Stages

按资料中的八个环节展开。煅烧设备与配料路线因工厂而异，具体工序顺序、温度曲线和添加剂以生产线与对应型号的工艺文件为准。

Eight documented operations are described below. Calcination equipment and batching vary by plant; confirm the actual sequence, temperature profile and additives against the production line and the model process file.

1. 原料进厂 / Raw material intake：脱硫石膏、磷石膏或天然石膏，主要成分为二水硫酸钙 CaSO₄·2H₂O。核对来源、批次与随车检测。FGD, phosphogypsum or natural gypsum, mainly calcium sulphate dihydrate CaSO₄·2H₂O. Check source, batch and accompanying tests.
2. 破碎粉磨 / Crushing & grinding：破碎至 <30 mm 后粉磨成细粉，控制细度与均匀性。Crush to <30 mm and grind to a fine powder; control fineness and uniformity.
3. 煅烧脱水 / Calcination：回转窑或沸腾炉加热，二水石膏转为 β 半水石膏粉。核对煅烧温度与相组成。Heat in a rotary or fluidised-bed kiln to convert dihydrate to β-hemihydrate; verify temperature and phase composition.
4. 陈化储存 / Ageing：冷却陈化以稳定凝结时间，避免可溶性成分波动。Cool and age to stabilise setting time and reduce soluble-phase variation.
5. 配料制浆 / Batching & slurry：加水并加入淀粉、发泡剂、缓凝剂、纤维等助剂。按型号配方核对配比与搅拌。Add water, starch, foaming agent, retarder, fibre and other additives; verify the model formulation and mixing.
6. 夹芯成型 / Forming：上下护面纸包芯挤压成型，控制纸面张力、芯材密实与边部成型。Extrude the core between top and bottom liner paper; control paper tension, core consolidation and edge forming.
7. 凝固切断 / Setting & cutting：初凝到终凝后按定长切割，检查板面与边型。After initial to final set, cut to length and inspect face and edge profile.
8. 干燥收尾 / Drying & finishing：干燥至资料口径含水率 ≤1%，再切边、封边、堆垛。核对含水率、断裂荷载抽检与堆垛标识。Dry to the stated ≤1% moisture, then edge-trim, seal and stack. Verify moisture, sampled breaking load and stack marking.

04 · 供货线与规格矩阵 / Supply Lines & Specification Matrix

下表保留产品资料中的规格、每张参考重量、资料起订量与每托张数，并按资料结构分为四条供货线。原表含销售价、常规尺寸报价与 FOB 单价等内部金额列，本页只删金额，保留全部规格与配置；重量为资料按密度核算值（耐水/耐火含阻燃板约 800 kg/m³、其他约 680 kg/m³、杰森玻纤面约 950 kg/m³），实际以磅重或检测为准。

The tables retain the documented size, reference weight per sheet, stated MOQ and sheets per pallet, grouped into the four supply lines. The source included internal selling prices, list prices and FOB unit prices; only those money columns are omitted here, while all specifications and configurations are kept. Weights are the material's density-based reference (about 800 kg/m³ for water/fire grades, 680 kg/m³ for others, 950 kg/m³ for JASON glass-fibre facing); verify against actual weight or testing.

05 · 各国石膏板标准对比 / International Standards Comparison

以下对比来自资料《石膏板标准汇总 2021》（资料标注由广东可耐福整理），用于说明不同市场关注的项目与典型限值差异。标准号与限值只代表对应框架，出口前须按目的国现行版本核验；本页不据此认定任一型号已满足全部市场要求。

The comparison below follows the material “Gypsum Board Standards Summary 2021” (attributed in the source to Guangdong Knauf) and shows how markets differ in test items and typical limits. A standard number and limit indicate a framework only; verify the destination market's current edition before export, and no claim is made here that any model meets all markets.

手机上可左右滑动宽表格查看各国家标准列。 / Swipe horizontally to view each national standard column.

旧版页面曾以单一断裂荷载和吸水率数字概括全部产品，本页不再沿用：表中数值属各标准框架的典型限值，不代表本页任一型号的实测结果。需要证明性能时，应提供对应型号的第三方检测报告并核对标准版本、测试项目、结果、样品与报告编号。The previous page summarised all products with single breaking-load and water-absorption figures; that is no longer used. The values above are typical limits within each framework, not measured results for any model here. To substantiate performance, provide a third-party report for the exact model and verify standard edition, test item, result, sample and report number.

06 · 耐水等级说明（EN 520 参考）/ Water-Resistance Grades (EN 520 Reference)

资料引用欧洲 EN 520 体系的 H1 / H2 / H3 耐水等级及对应吸水率、表面吸水量阈值。这些是标准框架中的分级定义，用于沟通“耐潮/耐水”的口径；本页不声称任一供货型号已取得某一等级，等级认定须以该型号的检测报告和声明为准。

The material cites the EN 520 H1 / H2 / H3 water-resistance grades with their absorption and surface-water thresholds. These are classification definitions used to align “moisture-resistant / water-resistant” language; this page does not claim that any supplied model has achieved a grade, which must rest on that model's test report and declaration.

常用区分：资料把普通板、耐潮板、耐水板、耐火板作为不同功能型号。耐潮/耐水通常以绿色护面纸作识别，但颜色不等于等级；同时市场上存在仅贴绿纸、未经耐潮处理的低端板。采购时应核对芯材配方、护面处理和对应吸水率报告，不能只凭颜色下单。Typical distinction: the material treats regular, moisture-resistant, water-resistant and fire-resistant boards as separate functional types. Green facing commonly identifies moisture/water grades, but colour is not the grade, and low-end boards that merely use green paper exist. Check core formulation, facing treatment and the matching absorption report.

“耐水板”不等于可长期浸水、可直接淋雨或可替代防水层。卫生间、厨房、地下室等潮湿部位仍需完整的防水、接缝和收边体系；持续潮湿或半室外部位应选用经完整系统验证的构造。A “water-resistant board” is not rated for permanent immersion or direct rain, and does not replace a waterproofing membrane. Wet areas still need a complete waterproofing, joint and trim system; continuously wet or semi-exterior locations require a fully verified assembly.

07 · 应用场景 / Applications

资料中“非洲走量、可耐福用于海外项目、杰森具备 CE/AS-NZS”等属于市场定位描述，不构成对任一具体项目的认证、准入或中标承诺；市场与品牌适用性须逐项目核实。Statements such as “volume lines for Africa”, “Knauf for overseas projects” and “JASON with CE/AS-NZS routes” are positioning notes, not certification, market access or award commitments for any project; verify market and brand suitability case by case.

08 · 选型层级与系统边界 / Selection Levels & System Boundary

石膏板只是系统中的一个部件。选型应自下而上锁定板材、龙骨系统、成品构造和环境，再回到板厚与型号。

The board is only one part of an assembly. Lock in the board, the framing system, the finished construction and the environment, then return to thickness and type.

轻钢龙骨与配件系统详见 吊顶与隔墙系统页面；隔墙的竖骨、天地骨、横撑、岩棉规格与方案构成在该页完整列出。Light-gauge framing and accessories are detailed on the ceiling & partition systems page, including studs, tracks, nogging and rock wool.

09 · 质量控制与文件核验 / Quality Control & Evidence

资料提出的 2h 抗折 2.5–3.8 MPa、含水率 ≤1%、±0.5/±0.6 mm 厚度允差等属资料口径或标准框架值，尚不构成所有产品已达标证据；应把“标准号＋样品型号＋结果＋条件＋报告编号”作为一组核验。放射性、甲醛/排放、耐火与隔声的结论都必须绑定具体型号和完整构造。The stated 2 h flexural 2.5–3.8 MPa, ≤1% moisture and ±0.5/±0.6 mm tolerance are material or framework figures, not proof that every product meets them. Verify “standard + sampled model + result + conditions + report number” as one set. Radioactivity, emissions, fire and acoustics must each bind to the exact model and full assembly.

10 · 包装、数量与装运核算 / Packing & Quantity Planning

资料按 40 尺高柜 16 托、每托约 1800 kg、限重 28.5 吨、20 尺柜 8 托的口径核算，托盘包装费属内部金额，本页不收录。每托张数因板型与厚度不同而异，不能跨产品线套用。

The material assumes a 40 ft HC container with 16 pallets, about 1800 kg per pallet, a 28.5 t limit and 8 pallets per 20 ft container; the pallet packing fee is internal money and is not reproduced. Sheets per pallet vary by type and thickness and cannot be carried across supply lines.

算例 / Example：一个内隔墙项目需覆盖 1000 ㎡，双面单层，则需板约 2000 ㎡；若选 1220×2440 mm（单张 2.9768 ㎡）并按 5% 损耗，用板约 2000×1.05÷2.9768 ≈ 706 张。For a 1000 ㎡ partition with two-sided single layer, about 2000 ㎡ of board is needed; with 1220×2440 mm sheets (2.9768 ㎡ each) and 5% waste, use about 2000×1.05÷2.9768 ≈ 706 sheets.

装运表应逐款列出箱/托数、净重与毛重、托盘尺寸与高度、总体积，并按实际柜型和路线校核重量。资料中的整柜面积估算与限重口径不直接作为装载承诺。A loading plan should list pallets, net and gross weight, pallet size and height, and total volume per SKU, then check weight against the actual container and route. The source's container estimates and weight convention are not confirmed loading capacities.

11 · 一次问清的询盘清单 / Complete Inquiry Checklist

尺寸与交付要点（资料口径，须逐单确认）：英制 1220×2440（资料称南方厂为主）与公制 1200×2400（资料称北方厂为主）需向客户确认；长度可定制（资料起订 5000 ㎡，杰森/可耐福最长 3000 mm），宽度一般不可定制（如澳洲 1350 mm 询盘国内通常难以安排）。起订量方面，资料列：普通/绿板为现货，真耐潮/耐火为 8000 ㎡，可耐福 10 / 13 mm 部分为 5000 ㎡，公制按整柜。Size and delivery notes (source terms, confirm per order): imperial 1220×2440 and metric 1200×2400 must be confirmed with the customer; length can be customised (source cites 5000 ㎡ minimum; JASON/KNAUF max 3000 mm) while width is generally not customisable (e.g. 1350 mm enquiries are usually hard to place). Stated MOQ: regular/green face as stock, true moisture/fire at 8000 ㎡, some KNAUF 10 / 13 mm at 5000 ㎡, metric by full container.

12 · 图册与文件入口 / Catalogues & Documents

石膏板及吊顶系统图册统一通过永久阅读页进入；图册中的规格、颜色和性能均以实物与对应型号文件为准。Gypsum board and ceiling system catalogues are reached through the permanent reader pages; specifications, colours and performance remain subject to the physical product and the model documents.
