Dab tsi yog qhov tshwj xeeb ntawm qhov cuam tshuam ntawm qhov kub thiab txias ntawm kev tiv thaiv corrosion ntawm fluoroplastic yeeb nkab?

Qhov cuam tshuam ntawm qhov kub ntawm qhov kev tiv thaiv corrosion ntawm fluoroplastic yeeb nkab yog qhov tseem ceeb hauv cov hauv qab no:
1. Kev hloov pauv ntawm cov khoom siv fluoroplastic
Kev hloov pauv hauv cov qauv molecular
Raws li qhov kub thiab txias, cov qauv molecular ntawm fluoroplastics yuav hloov mus rau qee yam. Piv txwv li, kev txav ntawm cov saw hlau molecular intensifies, uas tej zaum yuav ua rau ib tug tsis muaj zog ntawm intermolecular quab yuam. Qhov no yuav hloov lub cev lub cev ntawm fluoroplastics, yog li cuam tshuam lawv cov kev tiv thaiv rau corrosive media.
Siv polytetrafluoroethylene (PTFE) ua piv txwv. Ntawm qhov kub thiab txias, crystallinity ntawm PTFE yuav txo qis, thiab qhov tsis tu ncua ntawm cov saw hlau molecular raug rhuav tshem, uas txo nws cov corrosion kuj.
Txo hauv cov khoom siv kho tshuab
Qhov kub thiab txias yuav txo cov khoom siv ntawm fluoroplastics, xws li lub zog thiab hardness. Thaum cov kav dej fluoroplastic raug rau sab nraud los yog cov neeg kho tshuab kev ntxhov siab, lawv muaj feem ntau yuav deform lossis tawg, yog li muab cov channel rau corrosive media nkag mus rau sab hauv ntawm cov yeeb nkab thiab ua kom cov txheej txheem corrosion.
Piv txwv li, cov kav dej fluoroplastic siv nyob rau hauv qhov kub thiab txias ib puag ncig yuav ua rau tawg dua li ntawm chav tsev kub yog tias lawv raug cuam tshuam los ntawm sab nraud quab yuam, ua rau corrosive media nkag mus rau hauv cov yeeb nkab sab hauv thiab ua rau corrosion.
2. Txhim kho cov nyhuv corrosive media
Ua kom muaj tshuaj lom neeg ntxiv
Qhov kub nce siab yuav ua rau cov tshuaj lom neeg ua haujlwm ntawm corrosive media. Piv txwv li, cov khoom corrosive xws li cov kua qaub muaj zog thiab cov alkalis muaj zog ntau dua yuav ua rau cov tshuaj fluoroplastics ntawm qhov kub thiab txias, rhuav tshem cov qauv ntawm cov kav dej fluoroplastic thiab txo lawv cov corrosion kuj.
Piv txwv li, ntawm qhov kub thiab txias, tus nqi corrosion ntawm concentrated hydrochloric acid ntawm cov kav dej fluoroplastic tej zaum yuav ua kom nrawm dua, vim tias qhov kub siab ua rau lub zog ntawm hydrochloric acid molecules hnyav dua, thiab cov tshuaj tiv thaiv kev ua haujlwm nrog fluoroplastics tau txhim kho.
Accelerated diffusion tus nqi
Qhov kub thiab txias yuav ua kom nrawm nrawm ntawm cov khoom siv corrosive hauv fluoroplastics. Corrosive media tuaj yeem nkag mus rau sab hauv ntawm cov kav dej fluoroplastic los ntawm kev nkag mus, diffusion, thiab lwm yam, thiab cuam tshuam nrog cov kav dej. Thaum qhov kub thiab txias, lub thermal txav ntawm cov molecules intensifies, lub diffusion coefficient nce, thiab cov corrosive xov xwm yuav nkag mus rau hauv lub internal qauv ntawm fluoroplastic kav, li no accelerating tus txheej txheem corrosion.
Piv txwv li, nyob rau hauv ib cheeb tsam uas kub kub ntau lawm, corrosive gases los yog kua yog feem ntau yuav diffuse mus rau hauv lub sab hauv ntawm fluoroplastic kav thiab corrode cov kav dej.
3. Qhov sib txawv ntawm qhov cuam tshuam ntawm qhov sib txawv ntawm qhov kub thiab txias
Tsawg kub cuam tshuam
Nyob rau hauv qhov kub thiab txias, fluoroplastics feem ntau ua nyuaj thiab nkig. Txawm hais tias qhov kub thiab txias feem ntau tsis ncaj qha ua rau muaj qhov txo qis hauv kev tiv thaiv corrosion ntawm cov kav dej fluoroplastic, nce brittleness tuaj yeem ua rau cov kav dej ntau dua tuaj yeem tawg thaum raug kev cuam tshuam sab nraud lossis kev co, yog li muab lub sijhawm rau corrosive media nkag mus.
Piv txwv li, nyob rau hauv huab cua txias, cov kav dej fluoroplastic yuav tawg yog tias lawv raug tsoo, uas yuav ua rau muaj kev cuam tshuam ntawm cov xov xwm corrosive thiab ua rau muaj teeb meem corrosion.
Nruab nrab qhov kub thiab txias
Nyob rau hauv nruab nrab qhov kub thiab txias, qhov corrosion kuj ntawm cov kav dej fluoroplastic yog qhov ruaj khov. Txawm li cas los xij, nrog rau qhov kub thiab txias thiab ncua sijhawm ntawm kev pabcuam, qee qhov kev txhim kho corrosion kuj tseem tuaj yeem tshwm sim. Piv txwv li, qee cov fluoroplastics yuav maj mam cuam tshuam los ntawm qee cov xov xwm corrosive nyob rau hauv qhov kub ntawm 100 degree txog 200 degree, qhia me ntsis corrosion.
Piv txwv li, nyob rau hauv ib co txheej txheem cua sov, fluoroplastic kav nyob rau hauv ib tug nruab nrab kub ib puag ncig tej zaum yuav tshwm sim decoloration decoloration, nce roughness, thiab lwm yam tom qab siv mus ntev, uas tej zaum yuav tshwm sim los ntawm me ntsis corrosion.
Kub txwv
Thaum qhov kub nce mus txog lossis dhau qhov kev zam ntawm fluoroplastics, qhov kev tiv thaiv corrosion yuav poob qis heev. Nyob rau hauv cov huab cua kub heev, fluoroplastics yuav raug deformation loj heev, softening, los yog decomposition, tag nrho lawv tsis kam mus rau corrosive xov xwm.
Piv txwv li, thaum PTFE tshaj nws lub siab kub txwv (feem ntau 260 degree), nws yuav sai sai poob nws zoo heev corrosion kuj thiab yuav corroded heev los ntawm heev corrosive xov xwm.
