Mgbanwe na nguzogide corrosion nke akwa akwa okpomọkụ dị elu PTFE dị iche iche (Oxidants siri ike, Organic Solvents, wdg)

Wetara gị Jiangsu Aokai New Materials, a ọkachamara emeputa nke PTFE elu okpomọkụ ákwà.PTFE elu okpomọkụ ákwà bụ ama maka pụtara ìhè chemical kwụsie ike, deriving si siri ike molekụla Ọdịdị nke ya isi ihe - Polytetrafluoroethylene (PTFE). Mgbe ekpughere ya na mgbasa ozi kemịkalụ dị iche iche, nguzogide corrosion ya na-adịgide n'ozuzu ya, yana naanị ọnọdụ ole na ole pụrụiche chọrọ nlebara anya pụrụ iche. Edemede a na-akọwa n'ụzọ zuru ezu na mgbanwe arụmọrụ ya na gburugburu ọrụ dị iche iche.

1. Strong Oxidants: PTFE High Temperature Cloth Remains Chemically Inert

Na ike oxidizing gburugburu, corrosion eguzogide nke PTFE elu okpomọkụ ákwà sonso mgbanwe. Ọ na-eguzogide nbibi site n'ọtụtụ dịgasị iche iche nke oxidants siri ike, gụnyere potassium permanganate, hydrogen peroxide, sodium hypochlorite na potassium dichromate. N'ịbụ ndị na-erite uru site na nhazi ihe omimi ya nke ukwuu, ákwà ahụ anaghị emepụta mmeghachi omume kemịkalụ, ọzịza ma ọ bụ mmebi mgbe ọ na-akpakọrịta na oxidants ndị dị n'elu. Ya mere, mgbe a na-eji usoro kemịkalụ oxidation siri ike, a na-echekwa ike ya na ihe ndị dị n'elu ya nke ọma, na-ebuga ntụkwasị obi ọrụ ogologo oge.

2. Organic Solvents: Comprehensive Resistance Performance

Mgbe imikpu na organic mgbaze, PTFE elu okpomọkụ ákwà na-ekwusi ike kpamkpam corrosion iguzogide. Ọ na-egosipụta oke kemịkalụ inertness megide alcohols (ethanol), ketones (acetone), hydrocarbons aromatic (toluene, xylene), hydrocarbons halogenated, mmanụ ụgbọala, griiz na mkpuchi resin dị iche iche.

Data ule na-egosi na ọbụlagodi na 300 ℃, ọ bụ naanị ntakịrị alkanes na-esi ísì ụtọ na-akpata ntakịrị mgbasa. N'ime ụlọ okpomọkụ, PTFE akwa okpomọkụ ákwà agaghị igbari ma ọ bụ zaa ọ bụla mara organic solvent.When etinyere dị ka gaskets ma ọ bụ ebu belt substrates, ọ na-eguzogide penetration na mmebi site organic media, ukwuu ịgbatị ndụ ọrụ nke elu ya ọtọ Njirimara.

3. Acids, Alkalis na Salts: Ndakọrịta zuru oke

Na mgbakwunye na mgbasa ozi dị n'elu, akwa akwa okpomọkụ PTFE na-egosi mgbanwe arụmọrụ na-adịghị mma na acid siri ike, alkali siri ike na gburugburu nnu dị elu.

Ọ na-eguzogide imikpu ogologo oge n'ime sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid na ọbụna aqua regia. Ọ dịghị ihe pụtara ìhè ọnwụ ọnwụ ma ọ bụ n'ibu arụ ọrụ mbelata, ọbụna na esi ike acid. Ọ na-eguzogide mgbasa na ike imebi mgbe ekpughere ya na nnukwu okpomọkụ alkalis siri ike dị ka sodium hydroxide na amonia. N'ebe ikuku na-emebi emebi gụnyere mmiri mmiri, brine, chlorine gas na sọlfọ dioxide, ọ na-ejigide mkpanaka mbụ ya, na-eguzogide ihu igwe na ihe mkpuchi ọkụ eletrik.

4. Ọpụrụiche Pụrụ Iche: Ọnọdụ ọrụ dị oke mkpa ka a ga-ezere

Ọ bụ ezie na akwa akwa okpomọkụ dị elu nke PTFE nwere ụdị dị iche iche na-eguzogide corrosion, ọnụ ọgụgụ dị nta nke kemịkalụ pụrụ iche ga-ewepụ ọrụ nchebe ya.

Nke mbụ, a ghaghị izere kọntaktị na ọla alkali a wụrụ awụ (dị ka sodium na potassium), n'ihi na ihe ndị a ga-ebibi usoro ihe ọkụkụ molekụla ya. Nke abụọ, kpọmkwem ihe ndị na-emepụta fluorine siri ike (fluorine elemental, chlorine trifluoride) ga-eme ka mbuze, karịsịa n'okpuru okpomọkụ dị elu na ọnọdụ ọgba aghara.

Okpomọkụ bụkwa oke dị oke egwu: mgbe ọnọdụ okpomọkụ gafere 400 ℃, PTFE na-amalite ire ere ọkụ ma wepụta gas na-egbu egbu, na-ebute mfu ozugbo nke nguzogide corrosion na ike igwe.

Nchịkọta

N'ọtụtụ mgbasa ozi kemịkalụ ụlọ ọrụ mmepụta ihe, akwa akwa okpomọkụ PTFE na-edobe obere arụmọrụ. Nkwenye ya dị elu na-eme ka ọ bụrụ ihe dị mma maka mgbochi corrosion, akara na ntọhapụ Application.As long as contact with gbazee alkali ọla na ultra elu decomposition okpomọkụ na-ezere, ya magburu onwe corrosion eguzogide nwere ike n'ụzọ zuru ezu tinye n'ọrụ, ichebe ya irreplaceable ọnọdụ na siri ike chemical ọrụ ọnọdụ.
