Li-elastomer tse fapaneng tsa ho hanyetsa boemo ba leholimo ke life?
Ha u khetha rabara e ka mamellang likarolo tse ka sebelisoang ts'ebelisong efe kapa efe e itseng, hoa hlokahala ho utloisisa mekhoa e fapaneng eo boemo ba leholimo bo ka amang elastomer efe kapa efe, e tloaelehileng haholo:
-Khanya ea letsatsi
-Mocheso
- Ozone le UV
-Maemo a Leholimo a Setlehileng
Butyl:
Butyl e atisa ho sebelisoa e le thepa ea motheo ka lebaka la ho hanyetsa mahlaseli a letsatsi, ozone le botsofali ba mocheso, hammoho le lisebelisoa tse ling tse e fang khanyetso e ikhethang ea khase le mongobo (metsi le mouoane). Butyl e boetse e fana ka khanyetso e ntle ea ho hlapolla li-acids le alkalis hammoho le ho feto-fetoha ha maemo a mocheso o tlase.
EPDM:
EPDM e lumellana le mefuta e mengata ea lisebelisoa tse ling ha tlhahiso ea thepa e kopanya ka ho khetheha ts'ebetsong e itseng 'me e bonts'a khanyetso e hlaheletseng ea boemo ba leholimo, e leng ho etsang hore e be khetho e utloahalang bakeng sa tšebeliso ha lihlahisoa kapa likarolo li pepesehetse likarolo. EPDM e na le bokhoni ba ho hanela litlamorao tse mpe tsa ozone, oksijene, mocheso le boemo ba leholimo, hammoho le mefuta e mengata ea lik'hemik'hale le li-acid tse hlapollang le alkalis.
Hypalon:
Hypalon ke e 'ngoe ea lisebelisoa tsa motheo tse hanyetsanang le boemo ba leholimo tse fumanehang ka khanya ea letsatsi le khanya ea UltraViolet e nang le litlamorao tse fokolang holima sebopeho sa eona. Le ha li-elastomer tse ngata li qala ho senyeha ka maemo a ozone a 1 ppm moeeng, Hypalon e ntse e sa angoa ke likhakanyo tse fihlang holimo ho karolo e le 1 ho likarolo tse 100 tsa moea. Ke bokhoni bo botle ba ho amohela pigmentation e boetse e bolela hore metsoako ea 'mala ea Hypalon ha e nyamele ha e pepesehetse khanya ea letsatsi le UV.
Polyurethane:
Ha ho bapisoa le li-elastomers tse ling, polyurethane e fana ka khanyetso e ntle haholo ea abrasion le matla a thata, tseo ka bobeli li fetolelang ts'ebetso e phahameng maemong ohle a leholimo, hammoho le thepa e fanang ka khanyetso e ntle ho Ozone le mocheso o sebetsang o tlase ho -50 ° C le joalo ka ka holimo ho 90°C.
Silicone:
Silicone e nkoa e le sesebelisoa se feto-fetohang haholo se hanyetsanang le oksijene, ozone, leseli la UV, botsofali, boemo ba leholimo le mocheso o feteletseng.
Maemong a mangata, khetho ea thepa e hloka ho lumellana le lintlha tse ngata tse fapaneng tse amehang ho kenyelletsa le litlhaloso tsa tšebeliso ea motho ka mong, re sa lebale moruo oa boemo bo itseng.
