Abubuwan da suka dace na butyl rubber an ƙara su.Waɗannan kaddarorin kuma suna wanzu a cikin mannen butyl
(1) Karɓar iska
Gudun watsawa na iskar gas a cikin polymer yana da alaƙa da aikin thermal na ƙwayoyin polymer.Ƙungiyoyin methyl na gefe a cikin sarkar kwayoyin roba na butyl an tsara su sosai, wanda ke iyakance ayyukan zafi na ƙwayoyin polymer.Sabili da haka, ƙarancin iskar gas yana da ƙasa kuma ƙarancin iskar gas yana da kyau.
(2) Raunin zafi
Butyl roba vulcanizates suna da kyakkyawan juriya na zafi da rashin daidaituwa.Sulfur vulcanized butyl rubber za a iya amfani da shi a cikin iska na dogon lokaci a 100 ℃ ko ƙananan zafin jiki.Zazzabi na aikace-aikacen roba na butyl vulcanized na iya kaiwa 150 ℃ - 200 ℃.Thermal oxygen tsufa na butyl rubber nasa ne da nau'in lalacewa, kuma yanayin tsufa yana yin laushi.
(3) Shakar makamashi
Tsarin kwayoyin halitta na butyl rubber yana da ɗan gajeren ɗakuna biyu, kuma yawan tarwatsewar sassan sassan methyl yana da girma, don haka yana da kyawawan halaye na karɓar rawar jiki da tasirin tasiri.Halayen sake dawowa na butyl roba ba su wuce 20% ba a cikin kewayon zafin jiki mai faɗi (- 30-50 ℃), wanda ke nuna a fili cewa ƙarfin butyl roba don karɓar ayyukan injin ya fi sauran rubbers.Damping dukiya na butyl roba a babban gudun nakasawa yana cikin ɓangaren polyisobutylene.Ya zuwa babba, zafin aikace-aikacen ba ya shafar shi, matakin unsaturation, siffar vulcanization da canjin dabara.Don haka, roba butyl abu ne da ya dace don hana sauti da rage girgiza a wancan lokacin.
(4) Ƙimar ƙarancin zafin jiki
Tsarin sararin samaniya na sarkar kwayoyin roba na butyl yana karkace.Ko da yake akwai ƙungiyoyin methyl da yawa, kowane nau'i-nau'i na methyl da suka warwatse a ɓangarorin biyu na karkace suna jujjuyawa ta kwana.Saboda haka, sarkar kwayoyin roba na butyl har yanzu tana da taushin hali, tare da karancin zafin canjin gilashin da kyawu.
(5) Ozone da juriyar tsufa
Babban jikewa na sarkar kwayoyin roba na butyl yana sa ya sami juriya na ozone da juriya na tsufa.Juriya na ozone yana da kusan sau 10 sama da na roba na halitta.
(6) Rashin daidaituwar sinadarai
Babban cikakken tsari na roba butyl yana sa ya sami sabani na sinadarai.Rubber Butyl yana da kyakkyawan juriya ga mafi yawan inorganic acid da Organic acid.Ko da yake shi ba resistant zuwa mayar da hankali oxidizing acid, irin su nitric acid da sulfuric acid, shi zai iya tsayayya da wadanda ba oxidizing acid da matsakaici maida hankali oxidizing acid, kazalika da alkali mafita da hadawan abu da iskar shaka dawo da mafita.Bayan da aka jiƙa a cikin 70% na sulfuric acid na tsawon makonni 13, ƙarfin da haɓakar butyl rubber ba a rasa ba, yayin da ayyukan roba na halitta da styrene butadiene ya ragu sosai.
(7) Aikin lantarki
Rufin lantarki da juriya na corona na butyl rubber sun fi na roba mai sauƙi.Adadin juriya yana da sau 10-100 sama da na roba mai sauƙi.Matsakaicin dielectric (1kHz) shine 2-3 kuma ƙarfin ƙarfin (100Hz) shine 0.0026.
(8)Shan ruwa
Adadin shigar ruwa na butyl rubber yana da ƙasa sosai, kuma yawan sha ruwa a zafin jiki na yau da kullun ya yi ƙasa da na sauran roba, kawai 1 / 10-1 / 15 na ƙarshen.
