Bututun Teflon bututun fluoroplastic ne da aka yi daga kayan polytetrafluoroethylene ta hanyar haɗawa, yin amfrayo, latsa sanyi, sintering da sanyaya.
Teflon tubes suna da kyawawan kaddarorin:
① Low gogayya coefficient;
②lalata juriya: karfi acid da alkali juriya, kuma kusan duk sunadarai ba su amsa (a high zafin jiki da fluorine da alkali karfe dauki), iya tsayayya "Aqua regia" lalata;
③ Tsaftace kai: polytetrafluoroethylene yana da wuyar tsayawa;
④ Ba Flammable;
⑤High zazzabi juriya: PTFE teflon abu zazzabi iya isa -70 ° C ~ 260 ° C;
⑥ High Resistance: Teflon tube tare da babban juriya, kyakkyawan aikin haɓakawa;
⑦Anti-tsufa: Teflon Tube anti-tsufa aikin yana da kyau, tsawon rayuwar sabis.
Ba za a iya watsi da tsufa na tiyo na PTFE ba, aikin samfurori za a rage bayan tsufa, don haka, samar da marigayi, dole ne mu aiwatar da matakan da za a hana.
The m tef na Teflon bututu kayayyakin an vulcanized tare da sulfur curing tsarin. Za a iya inganta juriya na zafi na vulcanizate ta hanyar ragewa ko guje wa amfani da sulfur na asali, wanda zai iya ragewa ko kawar da haɗin gwiwar polysulfide kuma galibi yana samar da sulfur guda ɗaya ko disulfide giciye.
Yin amfani da peroxide ya zama dole don cimma kyakkyawan juriya na zafi, kamar yadda magani tare da peroxide yana haifar da haɗin gwiwar carbon-carbon wanda ya fi zafi. Ya kamata a biya kulawa ta musamman ga wasu additives lokacin amfani da peroxide. Alal misali, zaɓin antioxidants yana buƙatar zama mai ƙarfi, kamar yadda yawancin su tsoma baki tare da peroxide, vulcanization.
Bugu da ƙari, lokacin amfani da peroxide, rage adadin abubuwan da ke cikin acid don hana cations peroxide daga rubewa, yana haifar da ƙananan vulcanization na babban matsi mai ƙarfi (a cikin nau'i na ƙananan ƙarfi, ƙananan modulus da saitin matsawa mafi girma) . Ƙara abubuwan da ake buƙata na asali, irin su zinc oxide ko magnesium oxide, inda zai yiwu, yawanci na iya inganta haɓakar haɗin gwiwa na peroxide. Har yanzu suna da sakamako mai kyau na paraffin shine mafi kyau, kuna so ku guje wa amfani da man fetur na hydrocarbon aromatic da sauran ƙarfi.
