Utshintsho kwi-Corrosion Resistance ye-PTFE yeLaphu loBubushushu obuPhakamileyo kwiiMedia zeMichiza eyahlukeneyo (Ii-Oxidants ezomeleleyo, izinyibilikisi ze-Organic, njl.)

Iziswe kuwe nguJiangsu Aokai New Materials, umenzi oqeqeshiweyo we-PTFE ubushushu obuphezulu cloth.PTFE ilaphu lobushushu obuphezulu lidume ngokugqwesa uzinzo kwikhemikhali, eliphuma kubume bemolekyuli obuqinileyo bezinto ezingundoqo zalo — Polytetrafluoroethylene (PTFE). Xa ibonakaliswe kumajelo eendaba ahlukeneyo ekhemikhali, ukuxhathisa kwayo kokubola kuhlala kuhambelana ngokuqhelekileyo, kunye neemeko ezimbalwa ezikhethekileyo ezifuna ingqalelo ekhethekileyo. Eli nqaku lichaza ngokubanzi utshintsho lwalo lokusebenza kwiindawo ezahlukeneyo zenkonzo.

1. Ii-Oxidants Ezomeleleyo: Ilaphu le-PTFE lobushushu obuPhezulu lihlala liNgangeni ngokweMichiza

Kwiindawo ezisingqongileyo ezinamandla, uxhathiso lwe-PTFE lobushushu obuphezulu alitshintshi. Ixhathisa ukhukuliseko oluvela kuluhlu olubanzi lwee-oxidants ezinamandla, ezibandakanya i-potassium permanganate, i-hydrogen peroxide, i-sodium hypochlorite kunye ne-potassium dichromate.Ukuzuza kwisakhiwo sayo se-molecular ezinzile kakhulu, ilaphu alivelisi ukuphendula kweekhemikhali, ukudumba okanye ukuthotywa xa udibana nezi oxidants ezingentla. Ke ngoko, xa isetyenziswa kwiinkqubo zemichiza eyomeleleyo ye-oxidation, amandla ayo omzimba kunye neempawu zomhlaba zigcinwe kakuhle, zinikezela ukuthembeka kwenkonzo yexesha elide.

2. Izinyibilikisi ze-Organic: iNdlela eBanzi yokuNxhathisa

Xa untywiliselwa kwizinyibilikisi eziphilayo, i-PTFE ilaphu lobushushu obuphezulu ligcina ukuxhathisa okuzinzileyo kokumhlwa. Ibonisa ukunganyaniseki okugqithisileyo kweekhemikhali ngokuchasene ne-alcohols (ethanol), iiketoni (i-acetone), ii-hydrocarbons ezinevumba elimnandi (i-toluene, i-xylene), ii-halogenated hydrocarbons, i-petroli, igrisi kunye neentlobo ezahlukeneyo zokugquma kwentlaka.

Idatha yovavanyo ibonisa ukuba nakwi-300℃, zimbalwa kuphela ii-alkanes ezine-perfluorinated ezibangela ukunyibilika okuncinci. Kwiqondo lobushushu begumbi, ilaphu le-PTFE lobushushu obuphezulu aliyi kunyibilika okanye lidumbe kuyo nayiphi na i-solvent eyaziwayo ephilayo.Xa isetyenziswa njenge-gaskets okanye i-conveyor belt substrates, iyaxhathisa ukungena kunye nomonakalo ngamajelo e-organic, yandisa kakhulu ubomi benkonzo yomgangatho wayo osebenzayo.

3. Ii-Acids, iiAlkali kunye neeTyuwa: Ukuguquguquka okuPheleleyo kwemeko

Ukongeza kumajelo angasentla, ilaphu lobushushu obuphezulu be-PTFE libonisa utshintsho olungenamsebenzi kwi-asidi eyomeleleyo, i-alkali eyomeleleyo kunye neendawo ezinetyuwa eninzi.

Iyamelana nokuntywiliselwa ixesha elide kwi-asidi yesulfuric, i-nitric acid, i-hydrochloric acid, i-hydrofluoric acid kunye ne-aqua regia. Akukho kwehla kobunzima obucacileyo okanye ukwehla kokusebenza koomatshini okwenzekayo, nokuba kubiliswa iiasidi ezinamandla. Ikwamelana nokupheliswa kunye nokuthotywa kwamandla xa evezwe kubushushu obuphezulu bealkalis ezomeleleyo njengesodium hydroxide kunye neammonia. Amanzi. Kwimimoya enomhlwa equka amanzi olwandle, i-brine, igesi ye-chlorine kunye ne-sulphur dioxide, ihlala igcina iimpawu zayo zantlandlolo ezingeyona intonga, ukumelana nemozulu kunye nokugquma kombane.

4. Iimeko eziKhethekileyo eziKhethekileyo: IiMeko zokuSebenza eziBabekileyo ekufuneka ziphetshwe

Nangona ilaphu le-PTFE lobushushu obuphezulu linobuxhakaxhaka bokumelana nomhlwa, inani elincinane leekhemikhali ezikhethekileyo liya kucima ukusebenza kwalo olukhuselayo.

Okokuqala, ukudibana nesinyithi esinyibilikisiweyo se-alkali (njenge-sodium kunye ne-potassium) kufuneka kugwenywe, njengoko ezi zinto ziza kutshabalalisa isakhiwo sayo se-molecular chain chain.

Iqondo lobushushu likwangumda obalulekileyo: xa ubushushu be-ambient bungaphezulu kwe-400℃, i-PTFE iqala ukubola kwe-thermal kwaye ikhuphe igesi eyityhefu, okukhokelela kwilahleko ekhawulezileyo yokuxhathisa umhlwa kunye namandla oomatshini.

Isishwankathelo

Kwimithombo yeendaba ezininzi zeekhemikhali, ilaphu le-PTFE lobushushu obuphezulu ligcina ukuthomalalisa ukusebenza okuncinci. Ukunyamezela kwayo okungaphezulu kuyenza ibe yinto efanelekileyo yokunqanda ukubola, ukutywinwa kunye nokukhululwa Logama nje ukudibana nesinyithi esinyibilikisiweyo sealkali kunye namaqondo obushushu aphezulu okubola kuthintelwe, ukumelana kwayo nokugqwesa okugqwesileyo kunokusetyenziswa ngokupheleleyo, kukhuseleke indawo yayo engenakubuyiselwa kwiimeko ezinzima zokusebenza kweekhemikhali.

Lo mxholo unikwe nguJiangsu Aokai New Material Technology Co., Ltd.
