Calendering - nias PTFE-coated ntaub ntawm rhuab daim iav rollers ntawm 360-380 ° C - ua rau hloov qhov chaw morphology, tso tawm zog, impermeability, thiab txhua yam kev ua tau zoo. Nws txo qhov roughness ntawm Ra 0.5-1.0 μm mus rau <0.05 μm, ntsaws ruaj ruaj pinholes, txhim kho hnav tsis kam, tab sis txo cov kua muag zog thiab yooj. Qhov tseem ceeb rau kev tso tawm liners thiab hluav taws xob rwb thaiv tsev.

PTFE high-temperature npuag (PTFE membrane khoom) yog qhov kev xaiv zoo tshaj plaws rau tensile architecture. Cov txiaj ntsig tseem ceeb: 30+ lub neej nyob sab nraum zoov, qhov chaw tu tus kheej (cov dej nag ntxuav cov av), muag lub teeb kis tau tus mob (6-13%), Chav Kawm A hluav taws kub, thiab lub zog zoo li steel ntawm qis dua 1.5 kg / m². Siv nyob rau hauv chaw ntau pob, tshav dav hlau, thiab cov tsev iconic thoob ntiaj teb.
