　　In the construction and decoration market of Jinan, putty powder is a key material for wall treatment, and its quality directly affects the decoration effect and living experience. However, some low-quality putty powders often encounter a series of problems after construction, which not only affect their appearance but may also pose safety hazards. This article will indirectly demonstrate the characteristics that high-quality putty powder should possess by analyzing common defects in similar products.

　　開裂風(fēng)險(xiǎn)：基材適配性不足的隱患

　　Cracking risk: hidden danger of insufficient substrate compatibility

　　濟(jì)南氣候四季分明，冬季干燥寒冷、夏季潮濕悶熱，這種溫濕度劇烈變化對(duì)膩?zhàn)臃鄣娜犴g性提出嚴(yán)峻考驗(yàn)。部分低質(zhì)產(chǎn)品因配方單一，未針對(duì)不同基材（如混凝土、石膏板）調(diào)整粘結(jié)劑比例，導(dǎo)致墻面收縮率差異過大。施工后易出現(xiàn)龜裂紋，尤其在墻角、門窗洞口等應(yīng)力集中區(qū)域更為明顯。優(yōu)質(zhì)膩?zhàn)臃蹠?huì)采用復(fù)合型膠粉體系，通過可再分散乳膠粉與纖維素醚的科學(xué)配比，形成彈性膜層，有效緩沖基材形變，降低開裂概率。

　　Jinan has a distinct climate with four seasons, with dry and cold winters and humid and hot summers. This drastic change in temperature and humidity poses a severe challenge to the flexibility of putty powder. Some low-quality products have a single formula and have not adjusted the proportion of binders for different substrates (such as concrete and gypsum board), resulting in significant differences in wall shrinkage rates. Turtle cracks are prone to occur after construction, especially in stress concentration areas such as wall corners, door and window openings. High quality putty powder will use a composite rubber powder system, which forms an elastic film layer through a scientific ratio of redispersible latex powder and cellulose ether, effectively buffering substrate deformation and reducing the probability of cracking.

　　脫落隱患：界面處理技術(shù)的差距

　　Risk of detachment: gap in interface processing technology

　　濟(jì)南老舊小區(qū)改造項(xiàng)目中，墻面返堿、起砂問題頻發(fā)。劣質(zhì)膩?zhàn)臃垡蛭刺砑訉Ｓ媒缑嫣幚韯瑹o法與疏松基底形成有效咬合。施工時(shí)雖能短暫附著，但遇潮氣或機(jī)械振動(dòng)即發(fā)生空鼓脫落。優(yōu)質(zhì)產(chǎn)品則通過納米級(jí)滲透劑技術(shù)，使膩?zhàn)訉由钊牖奈⒖祝纬慑^固效應(yīng)。某品牌實(shí)驗(yàn)數(shù)據(jù)顯示，其產(chǎn)品在起砂混凝土表面的剝離強(qiáng)度可達(dá)0.8MPa，遠(yuǎn)超行業(yè)標(biāo)準(zhǔn)要求。

　　In the renovation project of old residential areas in Jinan, there are frequent problems of wall alkali return and sanding. Poor quality putty powder cannot form effective bite with loose substrates due to the lack of specialized interface treatment agents. Although it can temporarily adhere during construction, it will become hollow and fall off when exposed to moisture or mechanical vibration. High quality products use nanoscale penetrant technology to allow the putty layer to penetrate deep into the micropores of the substrate, forming an anchoring effect. According to experimental data from a certain brand, the peel strength of its product on the surface of sandblasted concrete can reach 0.8 MPa, far exceeding the industry standard requirements.

　　起泡現(xiàn)象：施工工藝兼容性缺陷

　　Bubbling phenomenon: compatibility defects in construction technology

　　在濟(jì)南高溫干燥的春秋季，部分膩?zhàn)臃垡虮Ｋ畡┡浔仁Ш猓┕ず蟊韺邮^快，內(nèi)部水汽無法均勻排出，形成針孔狀氣泡。這不僅影響批刮平整度，更會(huì)降低漆膜附著力。優(yōu)質(zhì)膩?zhàn)臃鄄捎镁從土u丙基甲基纖維素，通過控制水分釋放速率，確保膩?zhàn)訉优c基材同步固化。實(shí)際測試表明，在35℃環(huán)境下施工，其消泡時(shí)間可延長至40分鐘，為工人提供充足找平時(shí)間。

　　In the hot and dry spring and autumn seasons in Jinan, some putty powders lose water too quickly on the surface after construction due to an imbalance in the proportion of water retaining agents, and internal water vapor cannot be evenly discharged, forming needle shaped bubbles. This not only affects the smoothness of the scraping process, but also reduces the adhesion of the paint film. High quality putty powder is made of delayed setting hydroxypropyl methyl cellulose, which ensures synchronous curing of the putty layer and substrate by controlling the rate of water release. Actual tests have shown that the defoaming time can be extended to 40 minutes during construction at 35 ℃, providing workers with sufficient leveling time.

　　粉化問題：耐候性技術(shù)的短板

　　Powdering problem: Shortboard of weather resistance technology

　　濟(jì)南沿海區(qū)域空氣鹽分含量較高，普通膩?zhàn)臃壑械奶妓徕}成分易與氯離子發(fā)生化學(xué)反應(yīng)，導(dǎo)致粉化脫落。劣質(zhì)產(chǎn)品因未采用憎水型填料，吸濕后體積膨脹，加速粉化進(jìn)程。優(yōu)質(zhì)膩?zhàn)臃蹌t通過改性重鈣技術(shù)，在填料表面形成疏水膜層，阻隔鹽分侵蝕。某第三方檢測機(jī)構(gòu)模擬鹽霧試驗(yàn)顯示，優(yōu)質(zhì)產(chǎn)品經(jīng)1000小時(shí)測試后，粉化程度僅為0.3級(jí)（行業(yè)最高0級(jí)）。

　　The air salt content in the coastal areas of Jinan is relatively high, and the calcium carbonate component in ordinary putty powder is prone to chemical reactions with chloride ions, leading to powdering and detachment. Poor quality products, due to the lack of hydrophobic fillers, expand in volume after absorbing moisture, accelerating the pulverization process. High quality putty powder is modified with heavy calcium technology to form a hydrophobic film layer on the surface of the filler, blocking salt erosion. A third-party testing agency simulated a salt spray test, which showed that after 1000 hours of testing, the pulverization degree of high-quality products was only 0.3 level (the highest level in the industry is 0 level).

　　色差困擾：批次穩(wěn)定性控制不足

　　Color difference problem: insufficient control of batch stability

　　濟(jì)南大型精裝房項(xiàng)目常因膩?zhàn)臃叟紊顚?dǎo)致返工。部分小廠產(chǎn)品因未建立嚴(yán)格的質(zhì)量管理體系，原料波動(dòng)時(shí)未及時(shí)調(diào)整色漿配方。優(yōu)質(zhì)企業(yè)則采用全自動(dòng)計(jì)量投料系統(tǒng)，配合近紅外光譜檢測，確保每批產(chǎn)品白度值波動(dòng)控制在±1.5%以內(nèi)。某工地實(shí)際應(yīng)用對(duì)比顯示，使用優(yōu)質(zhì)膩?zhàn)臃鄣膲γ嫔瞀值≤0.8，肉眼幾乎無法察覺差異

　　Large scale furnished housing projects in Jinan often require rework due to color differences in putty powder batches. Some small factories have not established a strict quality management system for their products, and have not adjusted the color paste formula in a timely manner when the raw materials fluctuate. High quality enterprises adopt fully automatic measuring and feeding systems, combined with near-infrared spectroscopy detection, to ensure that the fluctuation of whiteness values in each batch of products is controlled within ± 1.5%. Comparison of actual applications at a construction site shows that the color difference Δ E value of walls using high-quality putty powder is ≤ 0.8, and the difference is almost imperceptible to the naked eye

　　濟(jì)南消費(fèi)者在選擇時(shí)，應(yīng)重點(diǎn)關(guān)注產(chǎn)品是否通過JG/T 298-2010《建筑室內(nèi)用膩?zhàn)印窐?biāo)準(zhǔn)檢測，特別是動(dòng)態(tài)抗開裂性、浸水后粘結(jié)強(qiáng)度等核心指標(biāo)。唯有如此，才能確保墻面裝修經(jīng)得起時(shí)間與環(huán)境的多重考驗(yàn)。

　　Jinan consumers should pay close attention to whether the product has passed the JG/T 298-2010 "Putty for Interior Use in Buildings" standard testing, especially the core indicators such as dynamic cracking resistance and bonding strength after immersion. Only in this way can we ensure that wall decoration can withstand the multiple tests of time and environment.
