Tsarin Kwayoyin Halitta na PTFE da Kyawawan Kayayyakinsa

A matsayin ƙwararren tushen masana'anta na masana'anta masu zafin jiki na PTFE, Jiangsu Aokai Sabbin Materials yana kawo muku fahimtar ƙwararru. Babban bangaren masana'anta mai zafin jiki na PTFE shine Polytetrafluoroethylene (PTFE), tare da tsarin kwayoyin halitta na (mathbf{-(CF_2-CF_2)_n-}). Babban sarkar carbon gaba ɗaya an naɗe shi da ƙwayoyin fluorine. Waɗannan manyan kaddarorin guda uku sun dace da fasalin tsarin ƙwayoyin PTFE a matakai daban-daban:

1. Kyawawan Kadarorin da ba na sanda ba

An samo shi daga makamashin ƙasa mara nauyi, wanda aka ƙaddara ta hanyar matsa lamba na atom ɗin fluorine  da rashin ƙarfi na ƙwayoyin cuta..

Babban  tasirin garkuwar ƙwayoyin fluorine: Fluorine yana da mafi ƙarfi na electronegativity da babban radius van der Waals. Shirya akai-akai kuma mai yawa a cikin karkace a gefen waje na sarkar carbon, ƙwayoyin fluorine suna samar da harsashi mai ƙarfi kuma suna haifar da cikakkiyar fili mai santsi.

Ƙarfin intermolecular mai  rauni: Ko da yake haɗin CF yana da ƙarfi mai ƙarfi, cikakken tsari na daidaitawa yana mayar da duk sarkar kwayoyin mara iyaka. Ƙwararrun tarwatsawa masu rauni ne kawai ke wanzuwa tsakanin ƙwayoyin cuta, wanda ke haifar da ƙarancin kuzarin ƙasa (kimanin 18 mN/m). Kusan babu wani abu da zai iya yadawa ko mannewa saman PTFE.

2. Karfin Acid & Alkaki Juriya

An samo shi daga ƙarancin haɗin haɗin sinadarai, wanda aka ƙaddara ta babban ƙarfin haɗin CF  da tasirin kariya mai ƙarfi.

Ƙarfin  CF bond: Ƙimar CF tana da ƙarfin haɗin gwiwa mai girma (kimanin 485 kJ/mol), ya fi kwanciyar hankali fiye da CH da CC bond, kuma yana da wuyar warwarewa.

Cikakken  kariya ta kariya: Babban harsashin zarra mai yawa na fluorine yana mamaye kwarangwal ɗin sarkar carbon, yana hana ions masu lalata tuntuɓar sarkar carbon mai rauni. Yana gane dual jiki da sinadarai kariya inert kariya.

3. Mafi Girman Insulation

An samo shi daga ƙananan ƙarancin polarizability da cajin sifili kyauta, an ƙaddara ta hanyar simintin kwayoyin halitta  da tasirin ɗaurin lantarki mai ƙarfi..

Tsarin haɗin kai wanda  ba na iyakacin duniya ba: Duk da polarity na gida na CF bond, cikakken tsari na daidaitaccen tsari na atom na fluorine a bangarorin biyu na sarkar carbon yana haifar da kusan sifili jimlar dipole na kwayoyin halitta, yana mai da PTFE wani abu na yau da kullun mara iyaka.

·  Electron da aka ɗaure da kyau: Ƙarfin electronegativity na zarra na fluorine yana jan gizagizai masu ƙarfi zuwa ga atom ɗin fluorine. Electrons a cikin kwayoyin halitta ba za su iya yin ƙaura ko shakatawa a ƙarƙashin filin lantarki na waje ba, tare da ƙarancin masu ɗaukar caji. Sabili da haka, PTFE yana alfahari da asarar ƙarancin dielectric mai ƙarancin ƙarfi da ƙarfin rushewa.

Takaitawa

Cikakken nannade sarƙoƙi na carbon ta hanyar zarra na fluorine, gajeriyar ƙarfi mai ƙarfi CF covalent bonds, da cikakken tsarin kwayoyin halitta marasa ƙarfi tare da ba da gudummawa ga ƙwararrun wasan kwaikwayo na PTFE: rashin tsayawa, juriya mai lalata da babban rufin lantarki.
