PTFE (gilashin fiber) membrane
Ana iya rarraba kayan membrane zuwa A, B, C, D da E bisa ga ƙarfinsa, nauyi da kauri.Zane ya kamata ya dogara ne akan ƙarfin ɗaukar tsari na matakan daban-daban na kayan membrane.
Babban abu na suturar ya kamata ya zama resin polytetrafluoroethylene, abun ciki ba zai zama ƙasa da 90% ba, kuma nauyin nauyin nauyin ya kamata ya fi 400g / m.Kauri na PTFE membrane ya kamata ya fi 0.5mm.
Zai iya hana lalata sinadarai da yashewar UV, ba sauƙin tsufa ba, a cikin ruwan sama tare da aikin tsabtace kai.
1. A Turai, Amurka, Japan da sauran ƙasashe, PTFE membrane an classified a matsayin A2 quasi-non-combustible abu.PTFE membrane a cikin wuta yanayi zafin jiki na fiye da 250 ℃, zai saki mai guba gas, Ma'aikatar Tsaron Jama'a wuta bincike Cibiyar ganowa, bisa ga GB8624 "ginin kayan konewa yi rarrabuwa Hanyar" aka classified a matsayin B1 refractory abu.
2. Lokacin tabbatar da ingancin kayan aikin jiki da sinadarai na membrane surface wanda masana'anta ke bayarwa shine shekaru 10.Koyaya, kayan aikin injiniya da physicochemical na membrane na PTFE ba su lalace ba bayan fiye da shekaru 20 na gwajin yanayi.
Kwatanta wasu kaddarorin ETFE, PVC da kayan masana'anta na PTEF.
1. ETFE membrane shine fim ɗin polyester guda ɗaya ba tare da masana'anta ba, wanda aka yi da gas kawai ana allura a cikin iskar gas don samar da memba mai ɗaukar hoto.
2. PVC membrane da PTFE membrane ne Multi-Layer aiki hada kayan aiki, tushen su ya ƙunshi fiber masana'anta, don haka yana da high creep juriya ikon, za a iya amfani da matsayin tsarin kayan.
3. Kwatanta wasu kaddarorin da farashin tunani tsakanin ETFE membrane da PVC da PTFE, membrane masana'anta guda biyu da aka saba amfani da su, ana nuna su a cikin tebur da ke ƙasa.
