甲醛超标5倍+！济南石膏腻子避坑，3招杜绝十年健康隐患

　　Formaldehyde exceeds the standard by 5 times! Jinan gypsum putty to avoid pitfalls, 3 tips to eliminate ten-year health hazards

　　在济南家装、工装施工中，石膏腻子是用量极大的基础辅材，看似不起眼，却因频发的甲醛超标问题，被业内称为“甲醛之王”，这绝非空穴来风。它的用量远超多数人的预期，家装单户用量半吨不算多，工装动辄需要几吨，一旦选用劣质产品，即便搭配几千元的高端乳胶漆也于事无补——石膏腻子铺设在乳胶漆下方，甲醛会被长期封闭，释放周期长达十年以上，持续危害家人健康，今天就结合实测数据，跟济南业主唠透避坑干货，教你快速识破劣质套路。

　　In Jinan's home decoration and workwear construction, gypsum putty is a widely used basic auxiliary material. Although it may seem insignificant, it is often referred to as the "king of formaldehyde" in the industry due to the frequent problem of excessive formaldehyde. This is not groundless. Its usage far exceeds the expectations of most people. A single household's usage of half a ton for home decoration is not much, while workwear often requires several tons. Once inferior products are selected, even high-end latex paint costing thousands of yuan is useless - gypsum putty is laid under latex paint, and formaldehyde will be sealed for a long time, with a release cycle of more than ten years, continuously endangering the health of family members. Today, based on actual test data, we will talk to Jinan homeowners about practical measures to avoid pitfalls and teach you how to quickly identify inferior tricks.

　　先理清核心：石膏粉本身不含甲醛，甲醛超标全源于厂家的偷工减料。为降低成本、提升粘结力，部分小厂家会违规添加含醛胶黏剂，这类胶黏剂甲醛含量可达3000mg/kg以上，是甲醛超标的主要源头。实测数据显示，济南建材市场上部分劣质石膏腻子，甲醛释放量超国标GB 18582-2020限值5倍以上，每公斤释放量高达250mg，而国标明确要求腻子甲醛含量≤50mg/kg、VOC含量≤100g/L，超标产品的危害可想而知。

　　First, clarify the core: gypsum powder itself does not contain formaldehyde, and the excessive formaldehyde is entirely due to the manufacturer's cutting corners. In order to reduce costs and improve adhesion, some small manufacturers may illegally add formaldehyde containing adhesives, which have a formaldehyde content of over 3000mg/kg and are the main source of formaldehyde exceeding the standard. Actual test data shows that some inferior gypsum putty in the Jinan building materials market has formaldehyde emissions exceeding the national standard GB 18582-2020 limit by more than 5 times, with a release rate of up to 250mg per kilogram. However, the national standard clearly requires putty formaldehyde content ≤ 50mg/kg and VOC content ≤ 100g/L, and the harm of products exceeding the standard can be imagined.

　　更值得警惕的是，济南建材市场还存在腻子缺斤短两的乱象，部分标注18公斤/袋的产品，实际重量仅9公斤，缺斤短两达50%，多是厂家低价竞争、偷工减料的套路，这类产品往往伴随甲醛超标问题，双重坑害消费者。而且石膏腻子施工后被乳胶漆覆盖，甲醛无法快速散发，会缓慢渗透，长期接触会引发呼吸道疾病、免疫力下降，对老人、儿童等易感人群危害尤甚。

　　What is even more alarming is that there is still a chaotic situation in the Jinan building materials market where putty is short of weight. Some products labeled as 18 kilograms per bag actually weigh only 9 kilograms, with a shortage of weight of up to 50%. This is often a tactic of manufacturers competing at low prices and cutting corners. Such products are often accompanied by excessive formaldehyde, which double harms consumers. Moreover, when gypsum putty is covered with latex paint after construction, formaldehyde cannot quickly dissipate and will slowly penetrate. Long term exposure can cause respiratory diseases and weakened immunity, which is particularly harmful to susceptible populations such as the elderly and children.

　　针对济南市场的劣质套路，教大家3招快速甄别，发现后立即停工止损。第一招，识破“偷天换日”旧标准套路。GB 18582系列是腻子有害物质限量的国家标准，最新实施的是2020版本，而部分劣质产品外包装仍沿用旧标准，意味着未按新规检测，甲醛等有害物质大概率超标，这类产品在济南建材市场占比约15%，坚决不能选。

　　In response to the low-quality tactics in the Jinan market, we will teach you three quick ways to identify and immediately stop work and stop losses once discovered. The first move is to see through the old standard routine of "stealing the sky and changing the sun". The GB 18582 series is a national standard for limiting harmful substances in putty, with the latest implementation being the 2020 version. However, some inferior products still use the old standard for packaging, which means that they have not been tested according to the new regulations, and harmful substances such as formaldehyde are likely to exceed the standard. Such products account for about 15% of the building materials market in Jinan and must not be selected.

　　第二招，避开“灯下黑”标准篡改陷阱。正规石膏腻子必须符合JG/T 298-2010《建筑室内用腻子》标准，该标准明确规定了粘结强度、有害物质限量等要求，其中耐水型腻子需通过96小时浸泡测试，标准中“T”代表弹性腻子类型，是合规标注的关键。但部分劣质产品会刻意漏写“T”，看似合规实则违规，本质是未达国标，无需犹豫直接淘汰。

　　The second trick is to avoid the "black under the light" standard tampering trap. Legitimate gypsum putty must comply with the JG/T 298-2010 "Putty for Interior Use in Buildings" standard, which specifies requirements such as bonding strength and harmful substance limits. Water resistant putty must pass a 96 hour immersion test, and the "T" in the standard represents the type of elastic putty, which is the key to compliance labeling. But some low-quality products intentionally omit the "T", which may seem compliant but actually violates regulations. Essentially, they do not meet national standards, so there is no need to hesitate and directly eliminate them.

　　第三招，警惕“偷工减料”违禁添加。国家早已明令禁止建筑胶水、香蕉水（用户所述“湿拿水”）等含大量甲醛的原料进入家装领域，而合格的济南石膏腻子，施工时只需添加清水和合规辅材即可，无需额外加胶。一旦施工工人要求额外添加胶水，大概率是劣质产品，需立即停工、更换材料，尽可能减少损失。

　　The third trick is to be alert to the prohibited addition of "cutting corners and materials". The country has already explicitly prohibited building adhesives, banana water (referred to as "wet water" by users) and other raw materials containing a large amount of formaldehyde from entering the home decoration field. Qualified Jinan gypsum putty only requires the addition of clean water and compliant auxiliary materials during construction, without the need for additional adhesives. Once construction workers request the addition of extra glue, it is likely to be a low-quality product that needs to be immediately stopped and materials replaced to minimize losses.

　　很多济南业主存在认知误区，觉得“石膏腻子是辅材，没必要选贵的”。实则劣质产品单价虽低，仅80-120元/吨，比合规产品便宜30%，但后续甲醛治理成本可能高达数万元，还会损害健康；合规石膏腻子单价约120-180元/吨，按单户家装1吨用量计算，仅多花几百元，却能将甲醛释放量控制在5mg/kg以内，接近零释放。

　　Many homeowners in Jinan have a misconception that "gypsum putty is an auxiliary material and there is no need to choose expensive ones". In fact, although the unit price of inferior products is low, only 80-120 yuan/ton, which is 30% cheaper than compliant products, the subsequent cost of formaldehyde treatment may reach tens of thousands of yuan, which can also harm health; The unit price of compliant gypsum putty is about 120-180 yuan/ton. Calculated based on a single household decoration usage of 1 ton, it only costs a few hundred yuan more, but it can control the formaldehyde release within 5mg/kg, approaching zero release.

　　最后提醒济南业主，选购时务必多留个心眼：一是认准GB 18582-2020和JG/T 298-2010双标准，索要国检报告，优先选带十环认证的产品；二是拒绝低价三无产品，警惕缺斤短两的袋装腻子，可现场称重核验；三是全程盯紧施工，杜绝工人额外添加违禁胶水。选对石膏腻子，才能从源头杜绝十年甲醛隐患，守护家人居住安全。

　　Finally, it is important to remind homeowners in Jinan to be cautious when making purchases: firstly, identify the dual standards of GB 18582-2020 and JG/T 298-2010, request national inspection reports, and prioritize products with ten ring certification; The second is to refuse low-priced products with three no's, and be wary of bagged putty that is short of weight, which can be weighed and verified on site; The third is to closely monitor the entire construction process and prevent workers from adding prohibited adhesives. Choosing the right gypsum putty can eliminate the ten-year formaldehyde hazard from the source and protect the safety of family living.
