Kodi PTFE Nsalu Yotentha Yotentha Kwambiri Motani?

M'mafakitale amankhwala, mizere ya electroplating, ndi nsalu za semiconductor, zida zimangowonetsedwa ndi zidulo zaukali, ma alkali, ndi zosungunulira. Kusankha zida zodzitetezera kumakhudza mwachindunji moyo wachitetezo ndi zida.

PTFE (polytetrafluoroethylene) nthawi zambiri amatchedwa 'mfumu ya pulasitiki' chifukwa cha kusagwira bwino kwa mankhwala. Koma 'inert' sikutanthauza 'kosagonjetseka' - ndi mankhwala ati omwe angawononge kwenikweni? Kodi kutentha ndi kukhazikika kwake kumakhudza bwanji ntchito yake?

Ku Aokai PTFE , takhala zaka zambiri tikuyesa Nsalu zokutidwa ndi PTFE motsutsana ndi chilengedwe chamankhwala enieni. Nkhaniyi ikugawana zomwe tapeza kuti zikuthandizeni kusankha mwanzeru.

Mankhwala Amene PTFE High-Temperature Fabric Imatsutsa

1. Ma Acid Amphamvu

Nsalu ya PTFE imapereka kukana kwambiri ku:

• Sulfuric acid (H₂SO₄)

• Nitric acid (HNO₃)

• Hydrochloric acid (HCl)

• Phosphoric acid (H₃PO₄)

• Ma acid okhala ndi okosijeni kwambiri monga aqua regia ndi hydrofluoric acid (HF)

2. Zida Zamchere Zamphamvu

Kusamva sodium hydroxide (NaOH), potassium hydroxide (KOH), ammonia water (NH₃·H₂O), ndi zinthu zina zamphamvu zamchere.

3. Organic Solvents

Mankhwala amadzimadzi motsutsana ndi zosungunulira zambiri za organic, kuphatikiza mowa (methanol, ethanol), ketoni (acetone, MEK), ma hydrocarbon onunkhira (benzene, toluene, xylene), ndi mafuta.

4. Mankhwala Ena

Imakhazikika polimbana ndi okosijeni (monga hydrogen peroxide), mchere (sodium chloride, sodium sulfate), ndi mpweya wowononga (chlorine, hydrogen sulfide).

Zochepa - Mankhwala Omwe Amawononga PTFE Nsalu

Ngakhale kukana mankhwala apamwamba, PTFE nsalu yotentha kwambiri imakhala ndi malire pansi pa kutentha kwambiri kapena kutsika kwambiri. Mankhwala angapo amatha kuwononga monga momwe tafotokozera pansipa:

Komanso, PTFE TACHIMATA nsalu si ovomerezeka ntchito ndi:

• Chlorine trifluoride (ClF₃) - kuyatsa modzidzimutsa kumatha kuchitika

• Oxygen difluoride (OF₂) - kuchita zachiwawa

• Fluorine yamadzi kapena mpweya (F₂) pa kutentha kwakukulu - imaukira PTFE

Zomwe Zimakhudza Kukaniza kwa Chemical kwa PTFE Coated Fabric

Zinthu zingapo zimakhudza kukana kwenikweni kwa dzimbiri kwa nsalu ya PTFE yotentha kwambiri pamapulogalamu apadziko lonse lapansi:

• Kutentha: Kukhazikika kwamankhwala kumasungidwa mkati mwa -70 ° C mpaka 260 ° C. Kukana kumachepa ndi mankhwala enaake pa kutentha kwambiri.

• Kuyikirapo: Kumizidwa kwa nthawi yayitali muzofalitsa zomwe zimawononga kwambiri zitha kusokoneza magwiridwe antchito azinthu. Kuyesa kwapamalo kumalimbikitsidwa.

• Kupsinjika kwamakina: Kuwonongeka kwamankhwala kuphatikiza ndi mikangano yamakina imathandizira kukalamba. Kuteteza zokutira za PTFE ku zipsera ndikofunikira - ikawonongeka, galasi lamkati la fiberglass limakhala pachiwopsezo.

• Nthawi yowonekera: Kukana kwa nthawi yayitali kumasiyana ndi kumizidwa mosalekeza.

• Kupanikizika: Kuthamanga kokwezeka kumatha kukakamiza mankhwala kukhala ma pores ang'onoang'ono kapena zopindika zokutira.

Deta ya labotale ya Aokai PTFE ikuwonetsa kuti kulumikizana kwa kutentha kwanthawi zonse kumachepetsedwa. Mwachitsanzo, PTFE nsalu kumatenga zaka 50% asidi sulfuric pa 100 ° C angasonyeze pamwamba whitening mkati miyezi 200 ° C ndi ndende chomwecho. Nthawi zonse ikani malire achitetezo.

Chidule - Kukaniza kwa Chemical kwa PTFE High-Temperature Fabric

Kwazinthu zambiri zamafakitale, PTFE nsalu yotchinga imapereka ntchito yodalirika, yokhalitsa. Komabe, nthawi zonse tsimikizirani kuyanjana pansi pazikhalidwe zenizeni zogwirira ntchito - makamaka kutentha, kukhazikika, komanso kupsinjika kwamakina.

Mwachidule, , nsalu ya PTFE yotentha kwambiri imapereka kukana kwambiri pafupifupi ma acid onse, alkalis, ndi zosungunulira organic mkati mwake momwe zimagwirira ntchito (-70°C mpaka 260°C). Zosiyana zazikulu ndi zitsulo zosungunuka za alkali ndi ma fluorinating amphamvu. Ma asidi otentha, oxidizing amafunikiranso kusamala kwambiri.

M'zochita, kutentha, kukhazikika, ndi kupsinjika kwa makina zimagwirira ntchito limodzi kukhudza moyo wakuthupi. Pazovuta kwambiri, timalimbikitsa kuyezetsa pamalopo kapena kugwiritsa ntchito malire achitetezo a 30-40 ° C pansi pa kutentha kwakukulu.

Mukufuna thandizo ndi malo enieni a mankhwala? Gulu laukadaulo la Aokai PTFE lapanga zidziwitso zowononga mazana azama media. Lumikizanani nafe kuti mupeze chitsogozo chosankha kapena njira zopangira nsalu za PTFE.

Yoperekedwa ndi Jiangsu Aokai New Materials Technology Co., Ltd.

Kuti mudziwe zambiri, zochitika zamagwiritsidwe ntchito, ndi njira zothetsera makonda azinthu zonse kuphatikizapo PTFE kutentha kwapamwamba, tepi ya PTFE yotentha kwambiri, lamba wa PTFE mesh, lamba wosakanizika, nsalu imodzi ya PTFE, lamba wonyamula kutentha kwambiri ndi fiberglass nsalu , chonde omasuka kulankhula nafe:

• Bambo Guo: +86 18944819998

• Bambo Liu: +86 13705266308

Timatsatira ukatswiri ndi umphumphu, odzipereka kuti apereke mayankho amtundu umodzi ndi ntchito zoganizira.
