Ingazweli Kangakanani Ngamakhemikhali I-PTFE Indwangu Yokushisa Okuphezulu?

Ezitshalweni zamakhemikhali, imigqa ye-electroplating, nezindwangu ze-semiconductor, okokusebenza kuhlala kuvezwe kuma-asidi anolaka, ama-alkali, nezinyibilikisi. Ukukhetha izinto ezivikelayo ezifanele kuba nomthelela ngqo ekuphepha kanye nempilo yezinto zokusebenza.

I-PTFE (i-polytetrafluoroethylene) ivamise ukubizwa ngokuthi 'inkosi yepulasitiki' ngenxa yokungangeni kwayo kwamakhemikhali ngokwedlulele. Kodwa 'inert' akusho 'ingenakunqotshwa' – yimaphi amakhemikhali angayilimaza ngempela? Izinga lokushisa nokugxilisa ingqondo kuthinta kanjani ukusebenza kwayo?

Kwa-Aokai PTFE , sichithe iminyaka sihlola Izindwangu eziboshwe nge-PTFE ngokumelene nezindawo zamakhemikhali zomhlaba wangempela. Lesi sihloko sabelana ngalokho esikutholile ukuze sikusize ukhethe ngokuhlakanipha.

Amakhemikhali I-PTFE High-Temperature Fabric Resists

1. Ama-Acid Aqinile

Indwangu ye-PTFE iletha ukumelana okuhle kakhulu ku:

• I-Sulfur acid (H₂SO₄)

• I-nitric acid (HNO₃)

• I-Hydrochloric acid (HCl)

• I-Phosphoric acid (H₃PO₄)

• Ama-asidi ane-oxidizing kakhulu njenge-aqua regia ne-hydrofluoric acid (HF)

2. Ama-alkali Anamandla

Imelana ne-sodium hydroxide (NaOH), i-potassium hydroxide (KOH), amanzi e-ammonia (NH₃·H₂O), nezinye izinto eziqinile ze-alkaline.

3. Izincibilikisi ze-Organic

Awenzi ngamakhemikhali ngokumelene nezincibilikisi eziningi eziphilayo, okuhlanganisa utshwala (i-methanol, i-ethanol), ama-ketone (i-acetone, i-MEK), ama-hydrocarbon anephunga elimnandi (i-benzene, i-toluene, i-xylene), nophethiloli.

4. Amanye Amakhemikhali

Igcina ukusebenza okuzinzile ngokumelene nama-oxidants (isb., i-hydrogen peroxide), usawoti (i-sodium chloride, i-sodium sulfate), namagesi abolayo (i-chlorine, i-hydrogen sulfide).

Imikhawulo - Amakhemikhali Alimaza Indwangu ye-PTFE

Naphezu kokumelana kwamakhemikhali okuphakeme, indwangu ye-PTFE yokushisa ephezulu inemikhawulo ngaphansi kwezimo eziphakeme kakhulu zokushisa noma zokugxila okuphezulu. Amakhemikhali athile athile angase abangele umonakalo njengoba kubalwe ngezansi:

Ukwengeza, indwangu eboshiwe ye-PTFE ayinconywa ukuthi isetshenziswe ne:

• I-Chlorine trifluoride (ClF₃) - ukuthungela okuzenzakalelayo kungenzeka

• I-oxygen difluoride (OF₂) - ukusabela ngobudlova

• I-fluorine ewuketshezi noma yegesi (F₂) emazingeni okushisa aphakeme - ihlasela i-PTFE

Izinto Ezithinta Ukumelana Kwamakhemikhali Kwendwangu Ehlanganisiwe ye-PTFE

Izinto eziningi zithinta ukumelana nokugqwala kwangempela kwendwangu ye -PTFE yezinga lokushisa eliphezulu ezinhlelweni zokusebenza zomhlaba wangempela:

• Izinga lokushisa: Ukusebenza kwamakhemikhali okuzinzile kugcinwa ngaphakathi -70°C kuya ku-260°C. Ukumelana namakhemikhali athile kuyehla emazingeni okushisa aphezulu kakhulu.

• Ukugxila: Ukucwiliswa isikhathi eside kumidiya egqwalile egqwalile kungase kuphazamise ukusebenza kwempahla. Kunconywa ukuhlola endaweni.

• Ukucindezeleka kwemishini: Ukugqwala kwamakhemikhali okuhlanganisiwe kanye nokungqubuzana kwemishini kusheshisa ukuguga. Ukuvikela ukunamathela kwe-PTFE ekuklwebheni kubalulekile - uma sekonakele, i-fiberglass engaphansi iba sengozini.

• Ubude besikhathi sokuchayeka: Ukumelana nokuchaphaza kwesikhashana kuyahluka ekucwilisweni okuqhubekayo.

• Ingcindezi: Umfutho ophakeme ungaphoqa amakhemikhali ukuthi abe nezimbotshana ezincane kakhulu noma amaphutha okunamathela.

Idatha yelebhu ye-Aokai PTFE ibonisa ukuthi ukusebenzisana kokugxilwa kwezinga lokushisa kuvame ukubukelwa phansi. Isibonelo, indwangu ye-PTFE ehlala iminyaka ku-50% sulfuric acid ku-100°C ingase ibonise ukumhlophe kwendawo phakathi nezinyanga ku-200°C nokugxiliswa okufanayo. Njalo sebenzisa imajini yokuphepha.

Isifingqo – Ukumelana Kwamakhemikhali kwe-PTFE High-Temperature Fabric

Ezindaweni eziningi zamakhemikhali ezimboni, indwangu eboshiwe ye-PTFE inikeza ukusebenza okuthembekile, okuhlala isikhathi eside. Kodwa-ke, qinisekisa njalo ukuhambisana ngaphansi kwezimo zokusebenza zangempela - ikakhulukazi izinga lokushisa, ukugxilisa ingqondo, nokucindezeleka komshini.

Kafushane , indwangu ye-PTFE enezinga eliphezulu lokushisa inikeza ukumelana okuvelele cishe kwawo wonke ama-acids, ama-alkali, nezinyibilikisi eziphilayo ngaphakathi kwebanga layo elivamile lokusebenza (-70°C kuya ku-260°C). Okuhlukile okubalulekile izinsimbi ze-alkali ezincibilikisiwe kanye nama-agent anamandla afaka i-fluorinating. Ama-acid oxidizing ashisayo, agxilile nawo adinga ukuqapha okwengeziwe.

Empeleni, izinga lokushisa, ukugxilisa ingqondo, nokucindezeleka kwemishini kusebenza ndawonye ukuze kuthinte ukuphila okubonakalayo. Ezimweni ezibucayi, sincoma ukuhlola endaweni noma ukusebenzisa imajini yokuphepha engu-30-40°C ngaphansi kwezinga lokushisa elilinganiselwe eliphezulu.
