Sidee Kiimiko ahaan U adkaysan Karaa Dharka Heerkulka Sare ee PTFE?

Dhirta kiimikaad, xadhkaha korantada, iyo qalabka semiconductor, qalabku waxa uu si joogto ah u soo gaadhay asiidhyada gardarada ah, alkalis, iyo dareerayaasha. Doorashada walxaha ilaalinta saxda ah waxay si toos ah u saameynaysaa badbaadada iyo nolosha qalabka.

PTFE (polytetrafluoroethylene) waxaa badanaa loogu yeeraa 'boqor caag ah' sababtoo ah firfircoonideeda kiimikada ee aadka u daran. Laakin 'inert' micneheedu maaha 'aan la guulaysan karin' -- kiimikdee ayaa dhab ahaantii wax u dhimi karta? Sidee heerkulka iyo feejignaanta u saameeyaan waxqabadkeeda?

Aokai PTFE , waxaan ku qaadanay imtixaan sanado ah Maro ku dahaaran PTFE oo ka soo horjeeda bay'ada kiimikaad ee dhabta ah. Maqaalkani waxa uu wadaagayaa natiijooyinkeena si uu kaaga caawiyo inaad si xikmad leh u doorato.

Kiimikooyinka PTFE Dhar Heerkulka Sarreysa iska caabisay

1. Asiidhyo xooggan

Dharka PTFE wuxuu bixiyaa iska caabin aad u wanaagsan:

• Sulfuric acid (H₂SO₄)

• Nitric acid (HNO₃)

• Hydrochloric acid (HCl)

• Phosphoric acid (H₃PO₄)

• Asiidh aad u oksaydhaysan sida aqua regia iyo hydrofluoric acid (HF)

2. Alkalis xooggan

U adkaysta sodium hydroxide (NaOH), potassium hydroxide (KOH), biyaha ammonia (NH₃ · H₂O), iyo walxaha kale ee alkaline ee xooggan.

3. Xalalka dabiiciga ah

Kiimiko ahaan ka soo horjeeda inta badan dareerayaasha organic, oo ay ku jiraan aalkolada (methanol, ethanol), ketones (acetone, MEK), hydrocarbons caraf udgoon (benzene, toluene, xylene), iyo shidaalka.

4. Kiimikada Kale

Waxay ilaalisaa waxqabadka xasilloon ee ka dhanka ah oksaydhiyeyaasha (tusaale, hydrogen peroxide), cusbada (sodium chloride, sodium sulfate), iyo gaaska daxalka ah (chlorine, hydrogen sulfide).

Xaddidaad - Kiimikooyinka Waxyeeleeya Dharka PTFE

Inkasta oo iska caabin kiimiko oo sarreeya, PTFE dhar heerkul sare ah ayaa leh xaddidaadyo heerkul aad u sarreeya ama xaalado feejignaan sare leh. Kiimikooyin gaar ah oo dhowr ah ayaa laga yaabaa inay waxyeelo u geystaan ​​sida hoos ku taxan:

Intaa waxaa dheer, dharka dahaarka leh ee PTFE laguma talinayo in lagu isticmaalo:

• Chlorine trifluoride (ClF₃) - shid kedis ah ayaa dhici karta

• Ogsajiin difluoride (OF₂) - falcelin rabshad leh

• Fluorine dareere ah ama gaas ah (F₂) oo heerkul sare leh - weerara PTFE

Waxyaalaha Saameeya Caabbinta Kiimikada ee Fabric Dahaaran ee PTFE

Waxyaabo badan ayaa saameeya iska caabbinta daxalka dhabta ah ee dharka heerkulka sare ee PTFE ee codsiyada adduunka dhabta ah:

• Heerkulka: Waxqabadka kiimikada ee deggan ayaa lagu hayaa -70°C ilaa 260°C. Iska caabintu waxay hoos ugu dhacdaa kiimikooyin gaar ah oo heerkul aad u sarreeya ah.

• Xoog-saarista: Dhex-gelidda muddada-dheer ee warbaahinta daxalka leh ee aadka u urursan waxay wax u dhimaysaa waxqabadka alaabta. Baaritaanka goobta ayaa lagula talinayaa.

• Cadaadiska makaanikada: Isku darka daxalka kiimikaad iyo is-jiidhka farsamada ayaa dedejiya gabowga. Ka ilaalinta dahaarka PTFE ee xagashada waa lama huraan - mar haddii ay dhaawacmaan, muraayadda hoose ee fiberglassku waxay noqotaa mid nugul.

• Muddada soo-gaadhista: Iska caabbinta qulqulka muddada-gaaban way ka duwan tahay quusitaanka joogtada ah.

• Cadaadiska: Cadaadiska sarreeya wuxuu ku qasbi karaa kiimikooyinka inay galaan daloolo yaryar ama cillado dahaarka.

Xogta shaybaadhka Aokai PTFE waxay tusinaysaa in isku-dubarid-saarida heerkulka inta badan la dhayalsado. Tusaale ahaan, dharka PTFE ee sanadaha ku jira 50% sulfuric acid at 100 ° C waxay muujin kartaa caddeynta dusha bilo gudahood 200 ° C oo leh isku-fiirsasho isku mid ah. Had iyo jeer codso xadka badbaadada.

Soo koobid - Caabbinta Kiimikada ee Dharka Heerkulka Sare ee PTFE

Inta badan deegaanka kiimikada warshadaha, dharka PTFE ee daboolan ayaa bixiya waxqabad la isku halleyn karo, oo muddo dheer soconaya. Si kastaba ha ahaatee, had iyo jeer xaqiiji ku waafaqid xaaladaha dhabta ah ee hawlgalka - gaar ahaan heerkulka, feejignaanta, iyo walbahaarka farsamada.

Isku soo wada duuboo , PTFE dhar heerkul sare leh ayaa bixisa iska caabin heersare ah oo ku dhawaad ​​dhammaan asiidhyada, alkalisyada, iyo dareerayaasha organic-ga ah ee ku dhex jira baaxadeeda shaqo ee caadiga ah (-70°C ilaa 260°C). Waxyaabaha muhiimka ah ee ka reeban waa biraha alkali ee dhalaalay iyo wakiilada fluoririnating xooggan. Asiidhyada oksaydhaynta ah ee kulul, urursan ayaa sidoo kale u baahan taxadar dheeraad ah.

Ficil ahaan, heerkulka, feejignaanta, iyo walbahaarka farsamada ayaa wada shaqeeya si ay u saameeyaan nolosha maaddada. Xaaladaha halista ah, waxaan kugula talineynaa in goobta lagu baaro ama lagu dabaqo xadka badbaadada 30-40°C ee ka hooseeya heerkulka ugu sarreeya.
