PTFE Imiterere ya molekulari nibyiza byayo

Nkumushinga wumwuga ukora PTFE yimyenda yubushyuhe bwo hejuru, Jiangsu Aokai Ibikoresho bishya bizana ubushishozi bwumwuga. Ibyingenzi bigize imyenda yubushyuhe bwo hejuru ya PTFE ni Polytetrafluoroethylene (PTFE), hamwe nimiterere ya molekile ya ( mathbf {- (CF_2-CF_2) _n -} ). Urunigi nyamukuru rwa karubone ruzengurutswe na atome ya fluor. Iyi mico itatu isumba iyindi ihuye nimiterere ya molekile ya PTFE murwego rutandukanye:

1. Umutungo mwiza utari inkoni

Bikomoka ku mbaraga zidasanzwe zo hejuru, bigenwa no gufunga hanze ya atome ya fluor  na molekuline itari polarite.

·  Ingaruka zikomeye zo gukingira atome ya fluor: Fluorine ifite electronegativite ikomeye na radiyo nini ya der der Waals. Mubisanzwe kandi byuzuye muburyo buzengurutse kuruhande rwinyuma rwumunyururu wa karubone, atome ya fluor ikora igikonjo gikingira kandi ikarema ubuso bwuzuye fluor.

·  Intege nke za intermolecular: Nubwo umurunga wa CF ari polar ikomeye, gahunda yuzuye ihuza imiterere ya molekile yose itari polar. Gusa imbaraga zo gukwirakwiza zibaho hagati ya molekile, bikavamo ingufu nkeya cyane (hafi 18 mN / m). Hafi ntakintu gishobora gukwirakwira cyangwa gukomera kubuso bwa PTFE.

2. Acide ikomeye & Alkali Kurwanya Kurwanya

Bikomoka kumurengera mwinshi cyane wa chimique, bigenwa ningufu nyinshi za CF  ningaruka zo gukingira.

·  Inkunga ikomeye ya CF: Inkunga ya CF igaragaramo ingufu zidasanzwe cyane (hafi 485 kJ / mol), ihagaze neza cyane kuruta CH na CC, kandi biragoye kuyimena.

·  Kurinda burundu gukingira: Igikonoshwa cyuzuye cya fluor atom gikubiyemo neza skeleton yumunyu wa karubone, ikabuza ion zangirika guhura numuyoboro wa karuboni wangiritse. Irabona uburyo bubiri bwo kurinda umubiri na chimique.

3. Amashanyarazi aruta ayandi

Bikomoka kuri polarizabilite nkeya cyane hamwe na zeru yubusa, bigenwa na molekuliyumu ya molekile  ningaruka zikomeye za electron.

·  Imiterere idafite inkingi: Nubwo polarite yaho ihuza imigozi ya CF, itunganijwe ryuzuye rya atome ya fluor kumpande zombi zumunyururu wa karubone bivamo umwanya wa zeru hafi ya zero ya dipole, bigatuma PTFE iba ibintu bisanzwe bidafite inkingi.

·  Electron ihambiriye cyane: Electronegativite ikomeye ya atome ya fluor ikurura ibicu bya electron neza kuri atome ya fluor. Electron imbere muri molekile ntishobora kwimuka cyangwa kuruhuka munsi yumuriro wamashanyarazi wo hanze, hamwe no kubura abatwara ibintu. Kubwibyo, PTFE irata ultra-low dielectric igihombo nimbaraga nyinshi zo gusenyuka.

Incamake

Gupfundikanya byuzuye iminyururu ya karubone na atome ya fluor, imiyoboro mito mito ya CF ya covalent, hamwe na molekuliyumu itunganijwe neza itagira polarike ifatanije hamwe bigira uruhare mubikorwa byihariye bya PTFE: kudafatana, kurwanya ruswa no kubika amashanyarazi menshi.

Ibirimo byavuzwe haruguru bitangwa na Jiangsu Aokai New Material Technology Co., Ltd.

Niba ukeneye amakuru yimbitse kubyerekeranye nibisobanuro birambuye, ibintu byakoreshejwe hamwe nibisubizo byabigenewe kubicuruzwa byacu byuzuye, harimo imyenda ya PTFE yubushyuhe bwo hejuru, kaseti ya PTFE yubushyuhe bwo hejuru, imikandara ya PTFE yubushyuhe bwo hejuru, imikandara ya fuser idafite ubudodo, umwenda umwe wa PTFE utwikiriye, udukingirizo twinshi twerekana ibirahuri,

Buri gihe twubahiriza amahame ya serivise yubunyamwuga nubunyangamugayo, kandi tubikuye ku mutima tuguha ibisubizo bimwe hamwe na serivisi yatekerejwe nyuma yo kugurisha.
