Kusintha kwa Corrosion Resistance of PTFE High Temperature Nsalu mu Different Chemical Media (Strong Oxidants, Organic Solvents, etc.)

Wobweretsedwa kwa inu ndi Jiangsu Aokai New Materials, katswiri wopanga PTFE kutentha kwambiri nsalu cloth.PTFE ndi otchuka kwambiri kukhazikika kwa mankhwala, zimachokera ku wangwiro maselo ake pachimake zakuthupi — Polytetrafluoroethylene (PTFE). Ikawonetsedwa kuzinthu zosiyanasiyana zamakina, kukana kwake kwa dzimbiri kumakhalabe kosasintha, ndikungokhala ndi zinthu zingapo zapadera zomwe zimafunikira chisamaliro chapadera. Nkhaniyi ikufotokoza mwatsatanetsatane za kusintha kwake kwa magwiridwe antchito m'malo osiyanasiyana ogwira ntchito.

1. Oxidants Amphamvu: PTFE High Temperature Nsalu Imakhalabe Mankhwala Inert

M'madera amphamvu oxidizing, kukana kwa dzimbiri kwa PTFE kutentha kwa nsalu sikumasintha. Imatsutsa kukokoloka kuchokera kuzinthu zambiri zamphamvu za okosijeni, kuphatikizapo potaziyamu permanganate, hydrogen peroxide, sodium hypochlorite ndi potaziyamu dichromate.Kupindula ndi mawonekedwe ake okhazikika a maselo, nsaluyo simapanga machitidwe a mankhwala, kutupa kapena kuwonongeka pamene ikukumana ndi zowonjezera zowonjezera. Chifukwa chake, ikagwiritsidwa ntchito pamakina amphamvu a okosijeni, mphamvu zake zakuthupi ndi mawonekedwe ake amasungidwa bwino, zomwe zimapereka kudalirika kwanthawi yayitali.

2. Organic Solvents: Comprehensive Resistance Performance

Pamene kumizidwa mu zosungunulira organic, PTFE mkulu kutentha nsalu amakhalabe khola dzimbiri kukana. Imakhala ndi kusakhazikika kwamphamvu kwamankhwala motsutsana ndi mowa (ethanol), ma ketoni (acetone), ma hydrocarbon onunkhira (toluene, xylene), ma halogenated hydrocarbon, petulo, mafuta ndi zokutira zosiyanasiyana za utomoni.

Zoyesa zoyesa zikuwonetsa kuti ngakhale pa 300 ℃, ma alkanes ochepa okha omwe amapangidwa ndi perfluorinated amachititsa kusungunuka pang'ono. Pa kutentha firiji, PTFE mkulu kutentha nsalu si kupasuka kapena pathupi aliyense kudziwika organic solvent.Pakagwiritsidwa ntchito ngati gaskets kapena conveyor lamba gawo lapansi, amakana malowedwe ndi kuwonongeka ndi organic TV, kwambiri kutalikitsa moyo utumiki wa pamwamba zinchito katundu.

3. Acids, Alkalis ndi Salts: Full Scenario Adaptability

Kuphatikiza pazomwe tafotokozazi, nsalu ya PTFE yotentha kwambiri ikuwonetsa kusintha kosasinthika kwa asidi amphamvu, malo amchere amphamvu komanso malo amchere ambiri.

Imapirira kumizidwa kwanthawi yayitali mu sulfuric acid, nitric acid, hydrochloric acid, hydrofluoric acid komanso aqua regia. Palibe kuwonda koonekeratu kapena kuchepa kwa magwiridwe antchito amakanika kumachitika, ngakhale pakuwotcha ma asidi amphamvu. Imakananso kusungunuka ndi kuwonongeka kwa mphamvu ikakumana ndi kutentha kwakukulu kwa alkalis monga sodium hydroxide ndi ammonia. Madzi. M'malo owononga mpweya monga madzi a m'nyanja, brine, mpweya wa chlorine ndi sulfure dioxide, nthawi zonse imakhalabe ndi mphamvu zake zoyambilira zomwe sizinali ndodo, zolimbana ndi nyengo komanso zotchingira magetsi.

4. Kupatulapo Kwapadera: Zinthu Zogwira Ntchito Kwambiri Zoyenera Kupewa

Ngakhale PTFE kutentha kutentha nsalu ali kwambiri dzimbiri kukana sipekitiramu, ochepa mankhwala apadera kulepheretsa ntchito yake zoteteza.

Choyamba, kukhudzana ndi zitsulo zosungunuka za alkali (monga sodium ndi potaziyamu) ziyenera kupewedwa, chifukwa zinthuzi zidzawononga maselo ake amtundu wamtundu.

Kutentha kulinso malire ovuta: pamene kutentha kozungulira kumadutsa 400 ℃, PTFE imayamba kuwola ndikutulutsa mpweya wapoizoni, zomwe zimachititsa kuti kutayika kwa dzimbiri ndi mphamvu zamakina kutayika nthawi yomweyo.

Chidule

M'mafakitale ambiri opangira mankhwala, nsalu ya PTFE yotentha kwambiri imasunga magwiridwe antchito pang'ono. Kulekerera kwake kwapamwamba kumapangitsa kukhala chinthu chabwino kwambiri chotsutsana ndi dzimbiri, kusindikiza ndi kumasula Malingana ngati kukhudzana ndi zitsulo zosungunuka za alkali ndi kutentha kwapamwamba kwambiri kumapewa, kukana kwake kwa dzimbiri kumatha kugwiritsidwa ntchito mokwanira, kuteteza malo ake osasinthika m'malo ovuta kwambiri ogwirira ntchito.

Izi zimaperekedwa ndi Jiangsu Aokai New Material Technology Co., Ltd.

Timapereka zinthu zambiri: PTFE nsalu yotentha kwambiri, tepi yotentha kwambiri ya PTFE, lamba wotentha kwambiri wa PTFE, lamba wosasunthika wamakina, nsalu imodzi yokhala ndi mbali imodzi ya PTFE, lamba wonyamula kutentha komanso kutentha kwambiri kosagwira fiberglass nsalu.Kuti mudziwe zambiri, zochitika zamagwiritsidwe ntchito ndi mayankho makonda, chonde lemberani:

· Bambo Guo: +86 18944819998

· Bambo Liu: +86 13705266308

Timatsatira nzeru zautumiki za ukatswiri ndi kukhulupirika, ndipo tadzipereka kukupatsirani njira zosiyanitsira limodzi ndi ntchito zosinthidwa mwamakonda.
