Kedu ihe kpatara eji eji akwa PTFE dị elu dị ka ihe mgbochi corrosion? 4 Isi Uru

N'ime osisi kemịkalụ, ebe a na-asachapụ ihe, na ebe a na-ahụ maka mmiri mkpofu, ihe mkpuchi akụrụngwa na-eche ọnọdụ obi ọjọọ ihu: acid siri ike, alkalis na-ekpo ọkụ, ihe mgbaze organic, na oke okpomọkụ. Ihe mkpuchi rọba zaa ma gbawaa. FRP lining ọnya. Igwe anaghị agba nchara corrodes.

PTFE akwa okpomọkụ dị elu (PTFE-coated fiberglass) na-eme ka ihe ọdịnala ndị a pụta ìhè. Ọ bụ kemịkalụ inert, okpomọkụ na-eguzogide, kwụsie ike size, na-abụghị osisi - niile n'ime otu.

Aokai PTFE enyela akwa PTFE maka ngwa mkpuchi corrosion ruo ọtụtụ iri afọ. N'okpuru bụ uru anọ dị mkpa, gbakwunyere ọmụmaatụ ngwa ụwa n'ezie.

Chemical Inertness - Na-eguzogide Ihe niile

Isi uru nke PTFE bụ nguzogide kemịkalụ ya dị nso. A na-akpọkarị ya 'Eze Plastics' maka ezi ihe kpatara ya.

1. Ihe ọ na-emegide

• Acid siri ike: Sulfuric, nitric, hydrochloric, phosphoric, na ọbụna aqua regia (ngwakọta nke nitric na hydrochloric acid nke na-agbaze ọla edo)

• Alkalis siri ike: sodium hydroxide, potassium hydroxide, amonia

• Ihe mgbaze organic: mmanya na-egbu egbu, ketones, hydrocarbons aromatic (toluene, xylene), ihe mgbaze chlorinated.

• Ihe ndị ọzọ na-emebi emebi: Oxidizers, salts, na ọtụtụ kemịkalụ ụlọ ọrụ

2. Ihe ọ na-adịghị emegide (mmachi)

• Ọla alkali a wụrụ awụ (sodium, potassium) - ga-ebibi PTFE

• Fluorine gas na ndị na-emepụta fluorine siri ike na okpomọkụ dị elu

• Hydrofluoric acid (HF) - na-awakpo mkpụrụ osisi fiberglass ma ọ bụrụ na mkpuchi ahụ nwere pinholes

Ihe bara uru: Maka ọrụ hydrofluoric acid, jiri ọkwa HF pụrụ iche ma ọ bụ hụ na mkpuchi PTFE enweghị pinhole kpamkpam (ọtụtụ mkpuchi na-agafe). Aokai PTFE na-enye akararị dị otú ahụ.

Oke okpomoku sara mbara - Site na oyi ruo na oke okpomoku

Mgbochi mgbochi corrosion na-echekarị ọ bụghị naanị kemịkalụ, mana oke okpomọkụ. PTFE ákwà na-ejikwa ma nsọtụ nke ụdịdị dị iche iche.

1. Ọrụ okpomọkụ dị elu

• Ọnọdụ okpomọkụ na-aga n'ihu: -70°C ruo 260°C

• Ọnụ kacha elu nke obere oge: 350C (njem njem dị nkenke)

• Nnwale ịka nká nke thermal: Mgbe ụbọchị 200 na-aga n'ihu na 250 Celsius, ike igwe anaghị egosi ọdịda doro anya.

2. Obere okpomọkụ arụmọrụ

• Na-agbanwe agbanwe ruo -70 Celsius

• Nwere ike iguzogide -180 Celsius (okpomọkụ nitrogen mmiri mmiri) na-enweghị mgbawa - ọ bụ ezie na mgbanwe na-ebelata.

3. Gịnị kpatara nke a ji dị mkpa maka ngwa ngwa

Na desulfurization akụrụngwa, flue gas nwere ike iru 200-250 Celsius. Ihe mkpuchi roba na-agbada karịa 120 Celsius. PTFE akwa na-aga nke ọma. Na nhazi kemịkalụ cryogenic (-50ºC), PTFE adịghị emebi emebi dị ka ọtụtụ plastik.

Ngwongwo anụ ahụ na arụrụ arụ - Stable, siri ike, na enweghị nkpado

E wezụga kemịkalụ na nguzogide okpomọkụ, akwa PTFE na-enye ọtụtụ uru ọrụ na-eme ka ọ bụrụ ihe mkpuchi mkpuchi mara mma.

1. Nkwụsi ike akụkụ (obere deformation)

Mkpụrụ fiberglass na-enye akwa akwa PTFE dị elu na ịdị elu dị ala - na-abụkarị <0.5% n'okpuru ibu. Nke a pụtara:

• Ihe mkpuchi ahụ anaghị agbatị ma ọ bụ na-akụda ka oge na-aga

• Enweghị mgbakasị ahụ ma ọ bụ mgbakasị ahụ n'ihi mgbasawanye ọkụ

• Na-ejigide ike nke ọma megide mgbidi akụrụngwa

2. Igwe anaghị agba nchara (nhịahụ dị mfe)

Ọnụọgụ esemokwu esemokwu PTFE dị obere ka 0.05-0.1 . Ọtụtụ ihe enweghị ike ịrapara n'elu ya. Maka mgbochi corrosion, nke a pụtara:

• Ihe fọdụrụ na mmeghachi omume kemịkalụ anaghị ewuli n'elu mkpuchi

• Nhicha n'etiti batches na-adị ngwa ngwa - ọtụtụ mgbe naanị ịsacha mmiri

• Ọ dịghị ihe nkwụnye kemịkalụ mịrị amịkpọ

3. Igwe ọkụ eletrik

• Dielectric mgbe niile <2.6

• Nnukwu olu resistivity (> 10⊃1; ⁵ Ω · cm)

• Kwesịrị ekwesị maka mkpuchi mkpuchi na ngwa eletrọnịkị na eletriki ebe nchekwa corrosion dịkwa mkpa

4. Mgbochi ịka nká na ọkụ retardant

• Nguzogide ihu igwe pụtara ìhè (ụkwụ UV)

• Nke na-adịghị ere ọkụ - na-ekpochapụ onwe ya (ụkpụrụ UL94 V-0)

• Enweghị nbibi enwere ike ịtụnye mgbe ọtụtụ afọ nke mkpughe n'èzí gasịrị

Asambodo ọkwa nri - Ọ dị mma maka nri na ọgwụ

Ọ bụghị ihe mgbochi corrosion niile kwesịrị ịbụ ọkwa nri. Ma mgbe ha na-eme - na nhazi nri, ọgwụ ọgwụ, ma ọ bụ ngwa mmiri ọṅụṅụ - PTFE ákwà na-ebuga.

1. Asambodo

• FDA 21 CFR 177.1550 - maka kọntaktị nri na-apụtaghị ìhè

• Iwu EU 1935/2004 - maka ihe kọntaktị nri

• Na-adịghị egbu egbu, enweghị isi ọbụna na elu okpomọkụ

• Enweghị ikenye ihe ndị na-emerụ ahụ n'ime nri ma ọ bụ ọgwụ

2. Ebe a na-eji akwa akwa nri

• Mpempe achịcha na oven liners na ebe a na-eme achịcha a na-ere ahịa (na-adịghị osisi, dị mfe ihicha)

• Ngwá ọrụ mmepụta ọgwụ - arịa mmeghachi omume na trays ihicha

• Ụgbọ mmiri na-edozi nri - ebe nri acidic ma ọ bụ mmanu na-akpọtụrụ mkpuchi

Ihe ngosi ngwa a na-ahụkarị maka lining mgbochi corrosion

Dabere na uru ndị a dị n'elu, a na-eji akwa okpomọkụ PTFE eme ihe na mpaghara ndị a:

1. Chemical na gburugburu ebe obibi

• pipeline Petrochemical - mkpuchi dị n'ime iji gbochie corrosion sitere na mmanụ crude, ngwaahịa a nụchara anụcha, na gas na-egbuke egbuke.

• Akụrụngwa desulfurization (osisi ike) - mkpuchi maka ihe nchacha, ductwork, na chimnis ebe flue gas nwere SOₓ na HCl.

• Ụgbọ mmiri mmeghachi omume na tankị nchekwa - mkpuchi maka tankị na-ejide acids, alkalis, ma ọ bụ ihe mgbaze ike.

• tankị pickling (nhazi igwe) - mkpuchi maka tankị nwere hydrochloric ma ọ bụ sulfuric acid maka nhicha ọla.

Data ubi sitere na Aokai PTFE: N'ime ụlọ elu desulfurization ụlọ ọrụ, akwa akwa PTFE dịruru afọ 3 na-enweghị ọdịda. Ihe mkpuchi roba na-adịbu naanị ọnwa 9. Nke ahụ bụ ndọtị ndụ 4x.

2. Ụlọ ọrụ nri na ọgwụ

• Mpempe achịcha na oven liners - anaghị arapara, dị mfe dị ọcha, FDA kwadoro

• Microwave gaskets - okpomọkụ na-eguzogide ma na-abụghị osisi

• Ngwá ọrụ mmepụta ọgwụ - ihe mkpuchi maka ihicha trays, ịgwakọta arịa, na mkpuchi mkpuchi mbadamba

3. Machinery na ngwá electronic

• Eriri ebufe okpomọkụ dị elu maka ndị na-ese fotovoltaic - jikọta mgbochi corrosion na enweghị osisi na nguzogide okpomọkụ.

• Okpomọkụ akara efere - PTFE ákwà dị ka ihe na-abụghị osisi mkpuchi

• Igwe na-ekpuchi ọkụ eletrik - ebe a chọrọ ma mkpuchi na nchedo corrosion
