本研究工作探讨了具有透气性的生橡胶,用10～30%的胶乳和70～90%的沥青组成的涂剂。研究了用喷浆(水泥混合物)和生橡胶张涂剂涂敷防火密闭的透气性问题。所谓防火密闭的空气切断方面也考虑了应用氯乙烯树脂(PVC)泡沫。它做为混凝土密闭的涂层,比粘合剂的透气性减少1/3。把粘土悬蜀液和氯化钙溶液注入防火密闭附近 This work explores the breathability of raw rubber, with 10 ~ 30% latex and 70 ~ 90% asphalt paint composition. The problem of air-tightness of fire-resistant closures with gunite (cementitious mixture) and raw rubber spreads was studied. The so-called fire-sealed air-cut applications also consider the use of vinyl chloride (PVC) foam. It is used as a concrete-encased coating, reducing air permeability by more than a factor of three. Suspension of clay and calcium chloride solution into the closed fire near
