PTFE High-Temperature Fabric-a Chemical Corrosion Resistance – A Tuar theih leh A Tuar Loh

Chemical plant-ah te, electroplating line-ah te, leh semiconductor fab-ah te chuan equipment lining leh conveyor belt-te chu chemical nasa tak takte beihna an tawk fo thin. PTFE high-temperature fabric (fiberglass cloth coated with polytetrafluoroethylene) hi a chemical inertness danglam tak avang hian chiang takin a sawi fo thin. Mahse 'almost universal' resistance hi 'universal' a ni lo – aggressive substance tlemte hian a bei thei a, temperature hian hmun pawimawh tak a chang a ni.

A hlawhtlinna zawng zawng – Near-Universal Chemical Inertness

PTFE high-temperature fabric hian chemical corrosion resistance danglam tak a nei a, engineering material hman tlanglawn zingah top tier zingah a tel. He core property hi pawn lam polytetrafluoroethylene coating atanga lo chhuak a ni a, hei hi carbon-fluorine (CF) bonds chak tak atanga siam niin chemical attack do thei a ni.

A hnuaia fiberglass substrate hi chemical inert a ni lo – mahse PTFE coating a awm reng chhung chuan fabric hian nearly inert material angin a thawk a ni. Regular operating temperature-ah chuan PTFE fabric hi acid chak tak tak, alkalis chak tak tak, organic solvent leh oxidizing agents tam zawk lakah a nghet hle a ni.

Wide Range of Resistant Media – PTFE Fabric hian eng nge a tih theih

Regular operating temperature-ah chuan acid chak tak tak, alkalis chak tak tak, organic solvent leh oxidizing agents tam zawk lakah chuan material chu a nghet hle a ni.

1. Acid chak tak tak

Concentrated sulfuric acid, nitric acid, hydrochloric acid, phosphoric acid, leh aqua regia (nitric leh hydrochloric acid inzawmkhawm, rangkachak tithianghlimtu) – PTFE hian a tuar vek a ni. Degradation teh theih a awm lo.

2. Alkali chak tak tak

Sodium hydroxide (NaOH) leh potassium hydroxide (KOH) solution te hian room temperature-ah nghawng tha lo a nei lo. Resistance hi alkaline environment tam zawkah a inzar pharh a ni.

3. Organic solvent hmanga siam a ni

PTFE hi solvent hriat zawng zawngah a insoluble lo. Ketones, alcohols, ethers, hydrocarbons, chlorinated solvents emaw solvent category dang emaw nena inzawm chuan a hring lo vang a, a hmin lo vang.

4. Oxidizing agents te

Hydrogen peroxide (H2O2) leh permanganates te ang chi oxidizer chak tak takte chu a tuar thiam hle.

5. Thil neih dangte

• Hydrolysis-resistant – tui emaw steam emaw in a nghawng lo

• Weather-resistant – UV leh pawn lama awm hian a tichhe tlem hle

• Oil-repellent leh non-stick – lei chunglam chakna tlem chuan adhesion a veng

• Tui lakluh dan – a takin zero (<0.01%) .

Exceptions – Chemicals fimkhur tur

PTFE hi universally resistant a ni lo. Thil awmdan khirh takah pawh chemical reactive tak tak tlemte nen a inrem a, hei hi material thlan laiin ngaihven bik a ngai a ni.

Aokai PTFE chuan heng exception te hi a tlem hle a , mahse hriat a pawimawh hle tih a sawi uar hle a ni:

H3: Alkali metals hmin tawh

Molten sodium (Na), potassium (K), leh lithium (Li) te hian PTFE chhunga carbon-fluorine bonds te chu a tichhia a, a tichhia vek a ni. Hei hi PTFE surface treatment atana sodium-naphthalene etching siamna principle a ni.

H3: Temperature sang leh pressure sang tak hnuaia halogen compound reactive tak tak

• Chlorine trifluoride (ClF3) hmanga siam a ni.

• Oxygen difluoride (OF2) hmanga siam a ni.

• Fluorine gas (F2) chu temperature leh pressure sang takah a awm thei

Hengte hian boruak khirh tak hnuaiah PTFE nen an inrem thei a, an kang thei bawk.

H3: Alkali chak tak takte chu temperature sang takah a hmin

Sodium hydroxide (NaOH) emaw potassium hydroxide (KOH) emaw aia sang a hmin chuan 300°C PTFE chu zawi zawiin a tichhe thin. Room temperature-ah chuan nghawng a nei lo.

H3: Hriat nawn tirna pawimawh tak – coating chhiatna hian fiberglass a pholang

A chunga kan sawi takte hi surface PTFE coating-ah chauh hman a ni. Coating chu a hrual, a chhiat emaw, pinhole a neih chuan a hnuaia fiberglass substrate chu a lang chhuak ang. Fiberglass hian:

• Hydrofluoric acid (HF) – glass fiber te chu rang takin a tithianghlim thin

• Alkali lum concentrated – glass a bei thin

Hei vang hian coating integrity vawn reng hi chemical service atan a pawimawh hle. HF nena inzawm application tan chuan pure PTFE film ngaihtuah zawk ang che.

Chemical Resistance-a Temperature-in nghawng a neih dan

Temperature hian chemical resistance enkawltu pawimawh tak angin hna a thawk a ni. Hun rei tak chhunga a service temperature range (a tlangpuiin -70°C atanga 260°C) chhungah hian PTFE chemical stability hi a nghawng lo tak zet a ni.

Mahse, sustained temperature 260°C aia sang chuan:

• Zawi zawiin PTFE chemical inertness chu tihhniam rawh

• A chunga kan sawi tak thil extreme tak takte hian material chu erosion hlauhawm zawkah siam rawh

• Thermal degradation ti chak a, chemical attack intan theihna hmun chak lohna siam

Aokai PTFE test data: 250°C continuous exposure-ah chuan PTFE fabric hian ni 200 hnuah a chemical resistance property >90% a vawng reng a ni. 280°C-ah chuan kar engemaw zat chhungin performance a tlahniam nasa hle.

Temperature sang (>260°C) leh chemical exposure pahnih nei application tan chuan technical data zawt la, application-specific testing ti rawh.
