(Summary description)Customized SILICONE STRUCTURAL SEALANT from China manufacturer refers to the adhesive with high strength, can bear large load, aging resistance, fatigue resistance and corrosion resistance, and has stable performance within the expected life. It is suitable for bearing the bonding of strong structural parts. Non structural adhesive has low strength and poor durability. It can only be used for bonding, sealing and fixing of ordinary and temporary properties, and cannot be used for structural adhesive bonding. NEUTRAL SILICONE WETHERPROOF SEALANT from China manufacturer is a structural adhesive with waterproof function. Silicone glue refers to the adhesive based on silicone rubber. According to different functions, it can be divided into structural adhesive, potting adhesive, sealant, thermal conductive adhesive, flame retardant adhesive and so on.

另一項(xiàng)已成功立項(xiàng)的國(guó)際標(biāo)準(zhǔn)是關(guān)于人造光透過(guò)玻璃暴露、熱和水對(duì)MS密封膠的粘接性能測(cè)定!此項(xiàng)國(guó)際標(biāo)準(zhǔn)規(guī)定了在實(shí)驗(yàn)室使用熱、水和人工光源循環(huán)暴露后MS密封膠粘接和內(nèi)聚性能的測(cè)定方法。該標(biāo)準(zhǔn)最后一次修訂時(shí)間為2002年8月,20多年來(lái)隨著老化儀器設(shè)備的技術(shù)進(jìn)步、試驗(yàn)方法的迭代,ISO/TC59/SC8待加快對(duì)其修訂,以對(duì)其儀器設(shè)備、試驗(yàn)程序等章節(jié)內(nèi)容進(jìn)行修改,引領(lǐng)MS密封膠行業(yè)的發(fā)展。
除此之外,ISO/TC59/SC8時(shí)刻關(guān)注可持續(xù)發(fā)展及生態(tài)問(wèn)題。建筑和土木工程MS密封膠的耐霉菌行為便是ISO/TC59/SC8研究的又一熱點(diǎn)問(wèn)題。MS密封膠在使用后,如果操作和清潔不當(dāng),產(chǎn)品表面極易積累污垢。這些污垢富含有機(jī)質(zhì),如果長(zhǎng)時(shí)間暴露于潮濕的環(huán)境中,很容易受到空氣中的霉菌影響,導(dǎo)致MS密封膠表面出現(xiàn)明顯的發(fā)霉發(fā)黑等現(xiàn)象。霉菌的快速生長(zhǎng)和繁殖不僅會(huì)影響視覺(jué)美觀效果,也會(huì)導(dǎo)致MS密封膠失去原本的密封和防水能力,嚴(yán)重者甚至產(chǎn)生更多毒素,進(jìn)而影響生態(tài)環(huán)境和人們的健康。
該標(biāo)準(zhǔn)規(guī)定了建筑施工中用于接縫的MS密封膠上5種最常見(jiàn)的微生物菌株生長(zhǎng)的評(píng)估方法。該方法通過(guò)在培養(yǎng)基表面接種并涂布霉菌抱子液,然后將試樣放置于培養(yǎng)基上,置于適合霉菌生長(zhǎng)的環(huán)境條件下進(jìn)行培養(yǎng)。培養(yǎng)結(jié)束后觀察霉菌在試樣表面的生長(zhǎng)情況,最后根據(jù)試樣表面長(zhǎng)霉面積評(píng)定其耐霉菌性。評(píng)定等級(jí)共分為6個(gè)等級(jí),即5級(jí)。近階段,ISO/TC59/SC8正在進(jìn)一步研究國(guó)際規(guī)范,用于定義更多場(chǎng)景和區(qū)域的防霉MS密封膠等級(jí)及分類,以完善此類國(guó)際標(biāo)準(zhǔn)體系。http://www.cs535.com/
