Me yasa PTFE Babban Zazzabi Cloth Ya Zama Mai Tauri da Gaggawa Bayan Amfani na Tsawon Lokaci a Babban Zazzabi?

Jiangsu Aokai New Materials, wani tushen masana'anta na PTFE high-zazzabi zane, bayyana hardening da embrittlement na PTFE high zafin jiki zane bayan tsawaita high zafin jiki sabis daga uku ra'ayoyi: polymer sarkar shakatawa, giciye-linking, da kuma lalata . Ya kamata a lura da cewa core abu na PTFE high-zazzabi zane ne polytetrafluoroethylene (PTFE), da wadannan bincike mayar da hankali a kan microstructural canje-canje na PTFE high-zazzabi zane.

I. Hudubar Sarkar Kwayoyin Halitta (Tsufawar Jiki)

A yanayin zafi mai zafi, motsi na sarƙoƙi na kwayoyin halitta a cikin yankunan amorphous na PTFE high-zazzabi zane yana ƙaruwa, kuma a hankali suna canzawa zuwa yanayin da aka ba da umarni, wanda ya haifar da mafi girma crystallinity. Wannan tsarin shakatawa na sarkar yana rage motsi na sassan kwayoyin halitta a cikin zane mai zafi mai zafi na PTFE, wanda macroscopically yana bayyana azaman abu yana canzawa daga sassauƙa zuwa mai ƙarfi da gaggautsa.

II. Ra'ayin Haɗin Kai

Lokacin da PTFE high-zazzabi zane da aka fallasa zuwa high yanayin zafi na dogon lokaci (musamman kusa ko wuce ta babba sabis iyaka), a gaban gano oxygen ko radiation, PTFE kwayoyin rasa fluorine atom don samar da free radicals, wanda sa'an nan jawo intermolecular giciye-linking. Cibiyar sadarwar da ke haɗin giciye kai tsaye tana ƙuntata dangi zamewar sarƙoƙi na kwayoyin halitta a cikin zane mai zafin jiki na PTFE, yana haifar da rasa sassauci. Wannan shine ɗayan mahimman dalilai na sinadarai don taurare da haɓakar zane mai zafin jiki na PTFE.

III. Ra'ayin Lalacewa

A mafi girma yanayin zafi ko a gaban oxygen, babban sarƙoƙi na PTFE high zafin jiki zane karya da kuma ƙasƙanta, samar da low-kwayoyin-nauyi gutsuttsura da saki fluoride gas. Kodayake kayan na iya yin laushi da farko, ci gaba da lalacewa yana haifar da raguwa mai kaifi a cikin nauyin kwayoyin halitta da lalacewa ga ainihin tsarin crystalline. Daga ƙarshe, saman PTFE mai zafin jiki mai zafi foda, fashe, kuma yana nuna ɓarna mara jurewa.

Summary : Lokacin da PTFE babban zane mai zafi yana zafi na dogon lokaci, shakatawa na sarkar (crystallization) da haɗin kai tare yana haifar da taurin kai da asarar taurin; a ƙarƙashin yanayi mai tsauri, lalacewa yana ƙara lalata amincin tsarin. Haɗin waɗannan abubuwa guda uku a ƙarshe yana sa PTFE babban zane mai zafi da ƙarfi da karye.
