Kedu otu esi eguzogide ọgwụ dị elu nke PTFE?

N'ime osisi kemịkalụ, ahịrị electroplating, na ihe ndị na-emepụta semiconductor, a na-ekpughe akụrụngwa mgbe niile na acid ike ike, alkalis na ihe mgbaze. Ịhọrọ ihe nchebe ziri ezi na-emetụta ndụ nchekwa na akụrụngwa ozugbo.

A na-akpọkarị PTFE (polytetrafluoroethylene) 'eze rọba' n'ihi oke kemịkalụ ya. Mana 'inert' apụtaghị ' enweghị ike imeri' - kemikal kedụ nwere ike imebi ya? Kedu ka okpomọkụ na itinye uche si emetụta arụmọrụ ya?

Na Aokai PTFE , anyị ejirila ọtụtụ afọ nyocha Akwa mkpuchi PTFE megide gburugburu kemịkalụ n'ezie. Edemede a na-ekekọrịta nchoputa anyị iji nyere gị aka họrọ nke ọma.

Chemicals nke PTFE Akwa-okpomọkụ ákwà na-eguzogide

1. Acid siri ike

Ngwa PTFE na-enye ezigbo nguzogide:

• Sulfuric acid (H₂ SO₄)

• Nitric acid (HNO ₃)

• Hydrochloric acid (HCl)

• Phosphoric acid (H₃PO₄)

• Acids oxidizing dị ukwuu dị ka aqua regia na hydrofluoric acid (HF)

2. Alkalis siri ike

Na-eguzogide sodium hydroxide (NaOH), potassium hydroxide (KOH), mmiri amonia (NH₃ · H₂O), na ihe ndị ọzọ siri ike alkaline.

3. Organic mgbaze

Kemịkalụ inert megide ọtụtụ ihe mgbaze organic, gụnyere alcohols (methanol, ethanol), ketones (acetone, MEK), aromatic hydrocarbons (benzene, toluene, xylene), na mmanụ ụgbọala.

4. Chemicals ndị ọzọ

Na-ejigide arụmọrụ kwụsiri ike megide oxidants (dịka ọmụmaatụ, hydrogen peroxide), nnu (sodium chloride, sodium sulfate), na gas na-emebi emebi (chlorine, hydrogen sulfide).

Ihe Na-emetụta Mgbochi kemịkalụ nke PTFE mkpuchi akwa

Otutu ihe na-emetụta nguzogide corrosion nke PTFE akwa okpomọkụ na ngwa ụwa n'ezie:

• Okpomọkụ: A na-edobe arụmọrụ kemịkalụ kwụsiri ike n'ime -70°C ruo 260°C. Nguzogide na-adaba megide kemịkalụ kpọmkwem na oke okpomọkụ.

• Ntinye uche: imikpu ogologo oge na mgbasa ozi na-emebi emebi nwere ike imebi arụmọrụ ihe. A na-akwado nnwale na saịtị.

• Nchegbu n'ọrụ: Nchikota kemịkalụ jikọtara ọnụ na esemokwu igwe na-eme ka ịka nká dịkwuo elu. Ichebe mkpuchi PTFE site na nchacha dị mkpa - ozugbo mebiri emebi, fiberglass dị n'okpuru na-aghọ ngwa ngwa.
