Chemical Lalata Juriya na PTFE High-Temperature Fabric - Abin da Yana Jurewa Kuma Abin da Ba Ya

A cikin shuke-shuken sinadarai, layukan lantarki, da masana'anta na semiconductor, rufin kayan aiki da bel na jigilar kaya suna fuskantar hari akai-akai daga sinadarai masu tsauri. PTFE high-zazzabi masana'anta (fiberglass rufi da polytetrafluoroethylene) sau da yawa ana kayyade daidai saboda ta na kwarai sinadaran inertness. Amma 'kusan duniya' juriya ba ' duniya ba' - wasu abubuwa masu tayar da hankali za su iya kaiwa hari, kuma zafin jiki yana taka muhimmiyar rawa.

Aokai PTFE ya gwada masana'anta na PTFE akan ɗaruruwan sinadarai. Wannan jagorar yana bayanin abin da yake tsayayya, abin da za a guje wa, da yadda zafin jiki ke shafar aiki.

PTFE masana'anta mai zafin jiki na musamman yana alfahari da juriya na lalata sinadarai na musamman, matsayi a cikin babban matakin kayan aikin injiniya na gama gari. Wannan ainihin dukiyar ta samo asali ne daga rufin polytetrafluoroethylene na waje, wanda ya ƙunshi ƙaƙƙarfan haɗin carbon-fluorine (CF) wanda ke tsayayya da harin sinadarai.

Ƙarƙashin fiberglass ɗin da ke ƙasa ba shi da ƙarancin sinadarai - amma muddin murfin PTFE ya ci gaba da kasancewa, masana'anta suna aiki azaman abu ne na kusan inert. A yanayin zafi na yau da kullun na aiki, masana'anta na PTFE suna tsayawa sosai a kan mafi yawan adadin acid mai ƙarfi, alkalis mai ƙarfi, abubuwan kaushi na halitta, da ma'aikatan oxidizing.

Faɗin Watsa Labarai na Resistant Media - Abin da Fabric na PTFE zai iya ɗauka

A yanayin yanayin aiki na yau da kullun, kayan yana da ƙarfi sosai a kan mafi yawan ƙarfi acid, alkalis mai ƙarfi, kaushi na halitta, da kuma abubuwan da ke haifar da iskar oxygen.

1. Karfin acid

Sulfuric acid mai mahimmanci, nitric acid, hydrochloric acid, phosphoric acid, da aqua regia (cakuda na nitric da hydrochloric acid wanda ke narkar da zinariya) - PTFE yana tsayayya da su duka. Ba a auna lalacewa da ke faruwa.

2. alkalis mai karfi

Sodium hydroxide (NaOH) da potassium hydroxide (KOH) mafita ba su da wani tasiri a zafin jiki. Juriya yana ƙara zuwa yawancin mahallin alkaline.

3. Organic kaushi

PTFE ba shi da narkewa a cikin duk sanannun kaushi. Ba zai kumbura ko narke ba lokacin da aka fallasa shi ga ketones, alcohols, ethers, hydrocarbons, chlorinated solvents, ko wani nau'in sauran ƙarfi.

4. Oxidizing jamiái

Yana nuna kyakkyawan juriya ga masu ƙarfi mai ƙarfi kamar hydrogen peroxide (H₂O₂) da permanganates.

5. Ƙarin kaddarorin

• Hydrolysis-resistant - ruwa ko tururi ba ya shafa

• Mai jure yanayi - UV da bayyanar waje yana haifar da ƙarancin lalacewa

• Mai hana man fetur da kuma ba tare da sanda ba - ƙananan makamashi na ƙasa yana hana mannewa

• Sha ruwa – yadda ya kamata sifili (<0.01%)

Banbance - Sinadaran da za a yi hattara da su

PTFE ba ta da juriya a duniya. Yana amsawa tare da ƴan kankanin adadin sinadarai masu saurin amsawa a ƙarƙashin matsanancin yanayi, waɗanda ke buƙatar kulawa ta musamman yayin zaɓin kayan aiki.

Aokai PTFE ya jaddada cewa waɗannan keɓancewar ba su da yawa amma suna da mahimmanci a sani:

H3: Narkar da alkali karafa

Molten sodium (Na), potassium (K), da lithium (Li) sun karya haɗin carbon-fluorine a cikin PTFE, suna haifar da lalacewa gaba daya. Wannan shi ne ka'idar bayan sodium-naphthalene etching don PTFE surface jiyya.

H3: Abubuwan haɓaka halogen mai ƙarfi a ƙarƙashin babban zafin jiki da matsa lamba

• Chlorine trifluoride (ClF₃)

• Oxygen difluoride (OF₂)

• Gas na fluorine (F₂) a matsanancin zafin jiki da matsa lamba

Waɗannan na iya amsawa tare da ko ma ƙone PTFE a ƙarƙashin matsanancin yanayi.

H3: Narkar da alkalis mai ƙarfi a yanayin zafi

Molten sodium hydroxide (NaOH) ko potassium hydroxide (KOH) sama da kusan 300°C a hankali yana lalata PTFE. A dakin da zazzabi, babu wani tasiri.

H3: Muhimmiyar tunatarwa - lalacewa mai lalacewa yana fallasa fiberglass

Iyakokin da ke sama sun shafi shafi PTFE kawai. Idan rufin ya karu, ya lalace, ko yana da ramuka, za a fallasa abin da ke cikin fiberglass substrate. Fiberglass yana da mummunan juriya ga:

• Hydrofluoric acid (HF) - yana narkar da zaruruwan gilashi da sauri

• Hot maida hankali alkalis - harin gilashi

Wannan shine dalilin da ya sa kiyaye amincin shafi yana da mahimmanci ga sabis na sinadarai. Don aikace-aikacen da suka shafi HF, yi la'akari da fim ɗin PTFE mai tsabta maimakon.

Tasirin Zazzabi akan Juriya na Chemical

Zazzabi yana aiki azaman muhimmin al'amari mai sarrafa juriyar sinadarai. A cikin kewayon zafin sabis na dogon lokaci (yawanci -70°C zuwa 260°C), kwanciyar hankalin sinadarai na PTFE kusan ba ya tasiri.

Koyaya, yanayin zafi mai dorewa sama da 260 ° C zai iya:

• A hankali rage rashin kuzarin sinadarai na PTFE

• Sanya kayan ya zama mafi haɗari ga zaizayarwa ta matsanancin abubuwan da aka ambata a sama

• Haɓaka lalata yanayin zafi, ƙirƙirar wurare masu rauni inda harin sinadari zai iya farawa

Bayanan gwajin Aokai PTFE: A 250 ° C ci gaba da bayyanar, masana'anta na PTFE suna riƙe> 90% na kaddarorin juriya na sinadarai bayan kwanaki 200. A 280 ° C, aikin yana raguwa sosai a cikin makonni.

Don aikace-aikace tare da babban zafin jiki (>260°C) da bayyanar sinadarai, tuntuɓi bayanan fasaha ko yin takamaiman aikace-aikacen gwaji.

Takaitawa – Lokacin Zaba Fabric na PTFE don Muhalli na Sinadarai

Aokai PTFE yana ba da yadudduka masu rufaffiyar PTFE don buƙatun yanayin sinadarai. Don aikace-aikacen da ke buƙatar juriya na HF ko ƙaƙƙarfan tabbacin sinadarai, muna ba da shawarar gwaji a ƙarƙashin yanayin aiki na ainihi ko amfani da makin fim na PTFE mai tsabta. Tuntuɓe mu tare da takamaiman sinadarai, zafin jiki, da lokacin fallasa don shawarwarin.
