Ku cinca eka ku tiya ka ku bola ka lapi ra PTFE ra mahiselo yale henhla eka swihangalasamahungu swohambana hambana swa tikhemikhali (Strong Oxidants, Organic Solvents, etc.)

Yi tisiwa eka wena hi Jiangsu Aokai New Materials, muendli wa xiphurofexinali wa lapi ra mahiselo ya le henhla ya PTFE.Lapi ra mahiselo ya le henhla ya PTFE ri dume hi ku tiya ka tikhemikhali loku xiyekaka, loku humaka eka xivumbeko xa molekhuli lexi tiyeke xa swilo swa yona swa nkoka — Polytetrafluoroethylene (PTFE). Loko yi hlangana na ti khemikhali to hambana hambana, ku lwisana ka yona na ku bola hi ntolovelo ku tshama ku ri loku nga cincekiki, laha ku nga na swiyimo swi nga ri swingani ntsena swo hlawuleka leswi lavaka nyingiso wo hlawuleka. Xihloko lexi xi andlala hi vuenti hi ku cinca ka matirhelo ya yona eka tindhawu to hambana ta vukorhokeri.

1. Ti-Oxidants ta Matimba: Lapi ra PTFE ra Mahiselo ya le Henhla ri tshama ri nga tirhi hi tikhemikhali

Eka tindzhawu leti tiyeke ta oxidizing, ku tiya ka corrosion ka PTFE high temperature cloth aswi cinci ngopfu. Yi lwisana na ku khuluka ka mati kusuka eka nxaxamelo wo anama wa ti oxidants to tiya, kukatsa na potassium permanganate, hydrogen peroxide, sodium hypochlorite na potassium dichromate.Hiku vuyeriwa eka xivumbeko xa yona xa molecular lexi tiyeke swinene, lapi leri ari humesi ti khemikhali, ku pfimba kumbe ku onhaka loko ri hlangana na ti oxidants letinga laha henhla. Hikokwalaho, loko yitirhisiwa eka maendlelo ya tikhemikhali ta oxidation yo tiya, matimba ya yona ya physical xikan’we na swivumbeko swale henhla swihlayisiwile kahle, leswi tisaka ku tshembheka ka kahle swinene ka vukorhokeri bya nkarhi woleha.

2. Ti Organic Solvents: Matirhelo ya ku Tiyisela loku heleleke

Loko yi cheriwa eka ti organic solvents, lapi ra mahiselo yale henhla ra PTFE ri hlayisa ku tiya loku tiyeke hiku hetiseka eka corrosion. Yi kombisa ku nga tirhi ngopfu ka tikhemikhali eka ti alcohols (ethanol), ketones (acetone), ti hydrocarbons to nun’hwela (toluene, xylene), ti halogenated hydrocarbons, petrol, grease na swifunengeto swohambana hambana swa resin.

Data ya swikambelo yikombisa leswaku hambi kuri eka 300°C, i ti alkanes titsongo ntsena letinga perfluorinated tivanga ku khuluka nyana. Eka mahiselo ya kamara, PTFE lapi ra mahiselo yale henhla ari nge n’oki kumbe ku pfimba eka organic solvent yin’wana na yin’wana leyi tivekaka.Loko yi cheriwa tani hi ti gaskets kumbe conveyor belt substrates, yi lwisana na ku nghena na ku onhaka hi organic media, leswi engetelaka swinene vutomi bya vutirheli bya swivumbeko swa yona swa ntirho wa le henhla.

3. Ti-acid, Alkali na Salts: Ku Cinca-cinca ka Xiendlakalo lexi heleleke

Ku engetela eka swihangalasamahungu leswinga laha henhla, lapi ra mahiselo yale henhla ya PTFE rikombisa ku cinca lokunga nyawuriki ka matirhelo eka tindzhawu ta acid yo tiya, alkali yo tiya na munyu wale henhla.

Yi tiyisela ku nyuperisiwa nkarhi woleha eka sulfuric acid leyi hlanganisiweke, nitric acid, hydrochloric acid, hydrofluoric acid hambi kuri aqua regia. Ku hava ku lahlekeriwa loku nga erivaleni ka ntiko kumbe ku hunguteka ka matirhelo ya michini loku humelelaka, hambi ku ri eka ku virisa ti- acid leti tiyeke. Yitlhela yi lwisana naku khuluka xikan’we naku onhaka ka matimba loko yi hlangana na mahiselo yale henhla ya ti alkali to tiya tofana na sodium hydroxide na ammonia mati.Eka swibakabaka leswi onhaka ku katsa na mati ya lwandle, brine, gasi ya chlorine na sulphur dioxide, yi tshama yi ri karhi yi hlayisa swivumbeko swa yona swo sungula leswi nga namarheli, leswi nga kotiki ku lwisana na maxelo na ku pfalela gezi.

4. Swihlawulekisi swo Hlawuleka: Swiyimo swo Tlula Mpimo swa Ntirho leswi Faneleke ku Papalatiwa

Hambi leswi lapi ra mahiselo yale henhla ra PTFE ringa na spectrum yo anama yo lwisana na ku bola, nhlayo yitsongo ya tikhemikhali to hlawuleka yita sivela matirhelo ya rona yo sirhelela.

Xosungula, ku khumbana na tinsimbi ta alkali leti n’okiweke (kufana na sodium na potassium) swifanele ku papalatiwa, tani hileswi swilo leswi swinga ta herisa xivumbeko xa yona xa molecular chain.Xavumbirhi, switirhisiwa swokarhi swo tiya swa fluorinating (elemental fluorine, chlorine trifluoride) swita vanga ku khukhuriwa, ngopfu ngopfu ehansi ka mahiselo yale henhla na swiyimo swa mpfilumpfilu.

Mahiselo na wona i mpimo wa nkoka swinene: loko mahiselo ya ndzhawu ya tlula 400°C, PTFE yisungula ku bola hi mahiselo naswona yi humesa gasi ya chefu, leswi endlaka leswaku ku lahlekeriwa hi xihatla ka ku lwisana na corrosion xikan’we na matimba ya michini.

Nkomiso

Eka swihangalasamahungu swotala swa tikhemikhali ta ti indasitiri, lapi ra mahiselo yale henhla ya PTFE ri hlayisa kuhunguteka ka matirhelo kutsongo. Ku tiyisela ka yona ka xiyimo xale henhla swiendla leswaku yiva nchumu lowunene eka anti corrosion, sealing naku humesa applications.Loko ntsena ku khumbana na tinsimbi ta alkali leti n’okiweke na mahiselo yale henhla swinene ya ku bola swi papalatiwa, ku tiya ka yona lokunene ka ku bola ku nga tirhisiwa hi ku hetiseka, ku tiyisisa xiyimo xa yona lexi nga cinciwiki eka swiyimo swo tika swa ntirho wa tikhemikhali.

Nhundzu leyi yi nyikiwile hi Jiangsu Aokai New Material Technology Co., Ltd.

Hi nyika nxaxamelo lowu heleleke wa switirhisiwa: PTFE lapi ra mahiselo ya le henhla, thepi ya mahiselo ya le henhla ya PTFE, bandi ra mesh ya mahiselo ya le henhla ya PTFE, bandi ra muchini ro hlanganisa leri nga riki na swirhabyani, lapi leri funengetiweke hi tlhelo rin’we ra PTFE leri pfanganisiweke, bandhi ra conveyor leri tiyiselaka mahiselo ya le henhla na lapi ra fiberglass leri tiyiselaka mahiselo ya le henhla.For vuxokoxoko bya tipharamitha, swiyimo swa xikombelo na swintshuxo leswi endleriweke wena, hi kombela u hi tihlanganisa:

· Tatana Guo: +86 18944819998

· Nkulukumba Liu: +86 13705266308

Hi seketela filosofi ya vukorhokeri ya vutshila na vutshembeki, naswona hi tiyimiserile ku ku nyika swintshuxo swo yima xin’we na vukorhokeri lebyi endleriweke wena hi ku anakanyisisa.
