Engvangin Nge PTFE High-Temperature Fabric hi Open Fire-ah Flame-Resistant a nih? A Microscopic Flame-Retardant Mechanism Chu Eng Nge Ni?

PTFE high-temperature fabrics siamtu lar tak Jiangsu Aokai New Materials chuan heti hian a sawifiah a:

PTFE high-temperature fabric hi open fire-ah chuan a kang thei hle a, a chhan ber chu a core material — polytetrafluoroethylene (PTFE) molecular structure leh thermal decomposition mechanism vang a ni. A flame retardancy hi thil pangngai angin added flame retardants-ah a innghat lo va, a pianphung chemical inertness leh unique decomposition behavior atanga lo chhuak a ni.

Hei hi level thum atanga hriatthiam theih a ni:

1. Molecular 'Armour' chak tak: Bond chakna sang tak leh venhimna layer

·  Carbon-fluorine (C–F) bonds chak tak : PTFE molecule hi carbon chain backbone atanga siam niin, fluorine atom-in a hual vel nghet hle. C–F bond hi chemical bonds hriat lar ber pawl a ni a, bond energy chu 485 kJ/mol vel a ni. A chhe tur chuan energy (temperature) sang tak tak a ngai a, chu chuan line of defense hmasa ber a siam a ni.

·  Fluorine atom te shielding effect : Fluorine atom lian tak tak, negative charge nei te hi densely packed an ni a, chu chu thick armor angin a thawk a, chu chuan inner carbon chain chu a hual vek a ni. He barrier hian chemical tam zawk (oxygen pawh tel) te chu carbon chain chhunga lut thei turin a veng a, combustion atana mamawh oxidation reaction te chu nasa takin a titawp bawk.

2. Non-Combustible Decomposition: Kang ai chuan Depolymerization tih a ni

·  Oxidation hmaa chain scission : Temperature sang hnuaiah chuan PTFE chhunga carbon-carbon (C–C) bonds chak lo zawkte chu C–F bonds hmain an break thin. Molecular chain te chu oxygen in reaction ah a tel hmain a chhe tan thin.

·  A siam chhuah ber chu monomer a ni : A chhe veleh PTFE hian depolymerization a paltlang ber a , chain tawp atang hian tetrafluoroethylene (C2F4) monomers a chhuak thin. Chu thil chu nasa taka kang ai chuan a vaporize a, chu chuan lumna leh kang thei gas tam tak a chhuah a ni.

·  Gas-phase barrier effect : Depolymerization atanga C2F4 gas hi boruak aiin a denser a, a chung bulah a awm a, temporary gaseous layer a siam a, chu chuan oxygen concentration a ti dilute a, combustion a titawp zual bawk.

3. Glass Fiber Substrate-in a puih theihna tur

PTFE high-temperature fabric hi glass fiber puan chunga PTFE coating hmanga siam composite a ni. Glass fiber ngei pawh hi kang thei lo inorganic material a ni. Structural skeleton a nih angin, a chunglam PTFE layer chu lumna nasa tak hnuaiah a ei kim vek a nih pawhin, a material chu plastic thianghlim angin a hmin emaw, a tla emaw lo tih a tichiang a, structural integrity a vawng reng a, meialh darh tur a veng bawk.

PTFE hi a ni tih hi sawi uar tur a ni.A flame-retardant , not completely non-flammable melting point (327°C) aia sang leh a lum chhunzawm zel chuan a chhe vek a, toxic fumes a chhuak thin. A tlangpuiin hun rei tak chhung 260°C thleng a tuar thei a, 300–360°C-ah pawh rei vak lo a awm reng bawk.

Decomposition in open fire : Open fire (a decomposition temperature aia sang zawk)-a direct-a dah a nih chuan PTFE layer chu a chhe vek a, mahse chutiang chuan kangmei chhuah chhunzawm zel turin lumna emaw, kang thei emaw a siam tling lo. Glass fiber support nen a inzawm chuan meialh a darh chhunzawm thei lo.

A tawi zawngin, PTFE high-temperature fabric hi a core material PTFE hi molecularly designed to resist combustion .High-energy chemical bonds, unique decomposition pathways, leh non-flammable glass fiber skeleton te hian an inzawm khawm chuan fireproof barrier chak tak an siam a ni.
