(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.

千法復(fù)臺(tái)單組分聚氨酯密封膠復(fù)合薄膜主要用于食品、醫(yī)藥、化妝品及飲料等的包裝,它不僅攜帶方便。且能保證產(chǎn)品的原有特性。隨著我國工農(nóng)業(yè)生產(chǎn)及出f=1貿(mào)易的日益發(fā)展,人民生活水平的不斷提高和旅游業(yè)的迅速興起,對軟包裝的需要日益增長。我國先后引進(jìn)和國內(nèi)自行設(shè)計(jì)安裝的復(fù)合生產(chǎn)線共多條,干法復(fù)合每年需單組分聚氨酯密封膠約5400噸。
目前國內(nèi)有多個(gè)單位研制、生產(chǎn)該類單組分聚氨酯密封膠。該膠均為單組分聚氨酯密封膠。各廠產(chǎn)品僅所用二醇、溶劑和固含量不同,主要生產(chǎn)單位有其中有自己研制的、有接受研究單位成果的、有引進(jìn)國外軟件技術(shù)的、也有軟、硬件全部引進(jìn)的,如引進(jìn)了一套食品包裝復(fù)合膜用單組分聚氨酯密封膠的生產(chǎn)線和相應(yīng)技術(shù),經(jīng)過消化、吸收、改造已能生產(chǎn)游離異氰酸酸含量在0.5%以下(符合衛(wèi)生標(biāo)準(zhǔn)),耐熱性可達(dá)11℃的單組分聚氨酯密封膠(塑/塑枯接)。其主劑固含量為75%以上時(shí),粘度)為帕秒、徐布性較好,質(zhì)量在國內(nèi)領(lǐng)先。若能將其成果推廣,則完全有可能取代干法復(fù)合用溶液膠的進(jìn)口品。若能進(jìn)一步提高單組分聚氨酯密封膠的耐溫等級,使其達(dá)到131,則該類單組分聚氨酯密封膠的應(yīng)用范圍將更加擴(kuò)大?傮w技術(shù)水平會(huì)進(jìn)一步提高。
日前國內(nèi)生產(chǎn)能力基本上能滿足需要。尚能生產(chǎn)無溶劑單組分聚氨酯密封膠在使故無污染公害;且其涂布星少,復(fù)合速度快、工效高、能耗低。加工成本相應(yīng)比溶劑墊低;但因我國僅有一臺(tái)龍?jiān)O(shè)備銷售量不大。該類膠在干法復(fù)合中的前景廣闊。需要大力推廣,且需設(shè)置相關(guān)設(shè)備,以進(jìn)一步提高復(fù)合。http://hbxqtax.com/
