Canje-canje a Tsarin Sinadarai: Babban Sarkar Scission da Oxidation

1. Babban Sarkar Scission da Rage Kaifi a Nauyin Kwayoyin Halitta

Hasken Gamma kai tsaye yana karya manyan sarƙoƙi na CC da sarƙoƙin gefen CF na PTFE. Adadin sinadaran sa na radiation (G-darajar) ya kai 3.0-3.5. Babban sarkar almakashi yana faruwa ko da a ƙananan allurai, wanda ke haifar da raguwar nauyin kwayoyin halitta. Masu kera na Tufafin zafin jiki na PTFE a Jiangsu suna la'akari da wannan a matsayin ainihin dalilin lalacewar aikin.

2. Maganganun Radical na Kyauta da Oxidation

Ƙarƙashin yanayin da ba shi da iskar oxygen, radicals na kyauta waɗanda ke haifar da sarkar sarkar suna fuskantar sake haɗuwa ko rashin daidaituwa don samar da gajerun perfluoroalkanes. A cikin yanayi na aerobic, radicals masu kyauta suna haɗuwa da sauri tare da oxygen don samar da peroxy radicals, haifar da halayen sarkar da ke kara karya sarƙoƙi na kwayoyin halitta da gabatar da ƙungiyoyi na ƙarshe kamar su acyl fluorides da acid carboxylic. Bayan fallasa zuwa danshi, acyl fluorides hydrolyze cikin carbonoxylic acid kuma ya saki hydrogen fluoride mai guba (HF), yana lalata kayan sosai.

Canje-canje a Tsarin Jiha Mai Ƙunƙasa: Crystallinity da Ilimin Halitta

1. Crystallinity Na Farko Sannan Faduwa

A ƙananan allurai (yawanci ƙasa da 50 kGy), babban sarkar scission yana samar da ɗimbin sassan sarkar gajere tare da ingantaccen motsi, wanda ke shirya cikin sauri cikin tsari da aka ba da umarni kuma yana haifar da haɓakar ƙarancin ƙima. Yayin da adadin radiation ya karu, lahani da yawa da samfuran lalacewa suna rushe tsarin crystal, kuma crystallinity yana raguwa daga baya.

2. Rushewar Tsarin Lamellar Crystal

Kamar yadda masana'antun PTFE babban zane mai zafin jiki suka bincika a Jiangsu: Sakamakon WAXS/SAXS ya nuna cewa sakawa a iska yana ƙasƙantar da ainihin band-kamar lu'ulu'u na tsawon lokaci na PTFE zuwa ƙarami, rarrabuwa crystallites. Tsarin da aka ba da umarni na dogon zango ya ɓace, tare da ƙananan lamellae crystal da ƙananan lahani.

Canje-canje na Macroscopic Properperty: Cikakkiyar lalacewa

1. Kayayyakin Injini (Mafi Girman Nuni)

Tsawaitawa a lokacin hutu ya fara raguwa da 0.1kGy kawai a cikin iska, kuma ya yi asarar sama da 90% a kusan 1kGy. Kayan gaba daya ya rasa tauri kuma ya zama m da gaggautsa. Ƙarfin ƙwanƙwasa na iya tashi dan kadan a matakin farko saboda karuwar crystallinity, sannan kuma raguwa mai sauri; modul na roba yana ƙaruwa, yayin da juriya da juriya na gajiya suka lalace sosai.

2. Thermal Properties

Lamellae crystal na bakin ciki da lahani a hankali suna rage ma'aunin narkewa daga 327 °C zuwa ƙasa da 310 °C, tare da rage yawan zafin jiki. Ƙungiyoyin tasha marasa ƙarfi akan sarƙoƙin polymer da alama suna rage zafin bazuwar zafin zafi na farko kuma suna ɓata kwanciyar hankali.

3. Kayan Lantarki da Bayyanar

Ƙungiyoyin Polar (misali, ƙungiyoyin carbonyl) waɗanda aka gabatar da su ta hanyar lalacewa kaɗan suna ɗaga madaidaicin dielectric da asarar dielectric. Fuskar kayan tana canzawa daga fari zuwa launin toka kuma daga ƙarshe baƙar fata, tare da hasara mai tsanani na sheki da ƙwanƙwasa.

1. Muhalli na Irradiation (Core Variable)

Lalacewar lalacewa a cikin iska ya fi muni fiye da ƙaƙƙarfan vacuum ko inert yanayi. Oxygen yana shiga cikin halayen sarkar iskar oxygenation na kai bayan sarkar sarkar, haɓaka haɓakar lalacewa da haifar da ƙungiyoyi masu cutarwa. Wannan shine ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun ƙayyadaddun aikace-aikacen PTFE a ƙarƙashin tasirin radiation.

2. Jimlar Kashi da Yawan Adadin

Jimlar adadin da aka sha yana ƙayyade matakin lalacewa gabaɗaya. Ƙarƙashin yanayi na aerobic, ƙananan ƙwayar ƙwayar ƙwayar cuta yana haifar da sakamako mafi muni fiye da yawan adadin kuzari. Oxygen yana da isasshen lokacin da za a ci gaba da yaduwa cikin kayan ciki, yana samar da manyan yadudduka na lalata oxidative da ƙarin daidaituwa da lalacewa sosai, yana ƙara haɓaka asarar kayan injin. Saboda haka, masana'antun PTFE high-zazzabi zane a Jiangsu sun kammala cewa PTFE gabaɗaya bai dace da yanayin radiation ba.
