(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.

碳足跡核算中的功能單位通常基于產(chǎn)品的產(chǎn)量為統(tǒng)計(jì)單位,本研究將功能單位定義為制備It建筑MS密封膠產(chǎn)品。碳足跡的系統(tǒng)邊界通常包括“搖籃到大門”和“搖籃到墳?zāi)埂瑑煞N不同的范圍,前者涵蓋了原材料的生產(chǎn)、運(yùn)輸以及制造過程,而“搖籃到墳?zāi)埂眲t進(jìn)一步包括了產(chǎn)品的分銷、使用及廢棄處理等后續(xù)階段的碳排放。鑒于MS密封膠產(chǎn)品下游用戶的復(fù)雜性,本研究未能獲取建筑MS密封膠在分銷、使用及廢棄階段的碳排放數(shù)據(jù),故采用“搖籃到大門”方法界定系統(tǒng)邊界,聚焦于原材料生產(chǎn)、運(yùn)輸及制造階段的碳排放,涵蓋原材料、耗材、包裝材料生產(chǎn)、原材料運(yùn)輸及能源生產(chǎn)等環(huán)節(jié),人力資源消耗則不計(jì)入系統(tǒng)邊界。
在典型建筑MS密封膠產(chǎn)品的制造過程中,碳排放源可分為直接排放和間接排放2個(gè)維度。依據(jù)LCA的理論框架,全面收集了三家龍頭企業(yè)典型建筑MS密封膠在原材料獲取、生產(chǎn)加工、運(yùn)輸?shù)汝P(guān)鍵環(huán)節(jié)的碳排放活動(dòng)水平數(shù)據(jù)。通過將原材料獲取、能源消耗等關(guān)鍵過程數(shù)據(jù)與區(qū)域化的碳排放因子進(jìn)行計(jì)算,可得到其生命周期內(nèi)的碳排放量。在確定不同材料的碳排放因子時(shí),本研究參考了《中國產(chǎn)品全生命周期溫室氣體排放系數(shù)集(2022))>S《建筑材料制造企業(yè)溫室氣體排放核算方法與報(bào)告指南(試行)》以及《企業(yè)溫室氣體排放核算方法與報(bào)告指南建筑行業(yè)》等相關(guān)文獻(xiàn)。此外,MS密封膠生產(chǎn)過程中的能源生產(chǎn)背景數(shù)據(jù)(包括電力、自來水等)運(yùn)輸背景數(shù)據(jù)源自開發(fā)的生命周期評價(jià)基礎(chǔ)數(shù)據(jù)庫。根據(jù)所收集的數(shù)據(jù),所有企業(yè)均選擇陸運(yùn)作為運(yùn)輸方式,其碳排放因子為0.12 kg/(tkm)。依據(jù)公式(1)和公式(4)計(jì)算得出3種產(chǎn)品在材料獲取階段的活動(dòng)水平數(shù)據(jù)。http://www.kzgjfl.cn/
