Membrane deg kev kho mob muaj xws li kev kho mob corona, kev kho ntshav plasma, tshuaj kho mob, kev kho photochemical, kev kho nplaim hluav taws, kev kho cov txheej txheem thiab lwm yam. Yog li dab tsi ntawm zaj duab xis nto kho txoj kev peb siv? Cov txheej txheem kho corona yog siv, thiab cov txheej txheem kho corona yog qhov paub tab, thiab nws tseem yog txoj hauv kev zoo tshaj plaws rau kev kho cov yas zaj duab xis tam sim no. Cia peb saib cov txheej txheem ua:
Lub luag haujlwm ntawm kev kho mob corona: tso tawm ntawm electrode thiab corona kho pas nrig los ntawm electrode kom ionize huab cua thiab tsim ozone thiab nitrogen oxide. Nyob rau tib lub sijhawm, cov hluav taws xob hluav taws xob siab thiab ions tawm tsam qhov chaw ntawm zaj duab xis, ua rau nws cov saw hlau molecules tawg, tsim cov dawb radicals, thiab oxidizing cross-linking cov tshuaj tiv thaiv nrog cov khoom corona ntawm huab cua los tsim cov pawg polar xws li hydroxyl thiab carbonyl pawg, txhim kho qhov nro thiab polarity ntawm zaj duab xis.
Lub zog hluav taws xob hluav taws xob hluav taws xob thiab Eons tau txhaj rau hauv zaj duab xis tsim cov zaj yeeb yaj kiab me me, uas coarses saum npoo ntawm zaj duab xis thiab nce cov kev ua si saum npoo av. Qhov ntub dej nro ntawm zaj duab xis nto yog cuam tshuam nrog lub zog ntawm kev kho mob corona. Qhov kev siv ntawm kev kho mob corona yog cuam tshuam nrog cov electrode voltage thiab qhov sib txawv ntawm cov electrode thiab cov corona cov menyuam. Qhov siab dua qhov hluav taws xob electrode, qhov me me ntawm qhov kev ncua deb ntawm cov electrode thiab corona cov menyuam, qhov muaj zog ntawm kev kho mob corona; Cov nyhuv kho ntawm cov yeeb yaj kiab kuj tseem cuam tshuam txog seb huab cua yog ntxig rau ntawm zaj duab xis thiab corona yob, yog tias muaj huab cua nruab nrab ntawm cov yeeb yaj kiab thiab corona yob, nws yuav ua rau sab nraub qaum ntawm cov yeeb yaj kiab raug kho, uas tuaj yeem ua rau. mus rau qhov deterioration ntawm lub tshav kub sealing kev ua tau zoo ntawm cov zaj duab xis rov qab, nyob rau hauv tas li ntawd, nws kuj muaj feem xyuam rau kev huv si ntawm corona yob thiab electrode nto, yog hais tias lub corona yob thiab electrode nto yog qias neeg, nws yuav tsis muaj zog cov nyhuv ntawm corona. kev kho mob
Qhov sib ntxiv ntawm cov tshuaj ntxiv kuj tseem muaj qee yam cuam tshuam rau lub polarity thiab qhov nro ntawm cov yeeb yaj kiab nto. Cov khoom siv feem ntau siv hauv BOPET films yog cov tshuaj tiv thaiv adhesion, feem ntau silica. Lub silicon-oxygen daim ntawv cog lus nyob rau hauv silicon dioxide muaj zog polarity, thiab nto ntawm silicon dioxide hais feem ntau adsorbed nrog ib tug tej yam nqi ntawm cov dej thiab hydroxyl, yog li cov silicon dioxide hais tawm nyob rau saum npoo ntawm zaj duab xis pab ua kom lub polarity thiab nto nro ntawm zaj duab xis nto, uas yog conducive rau txhuas plating. Qee lub sij hawm, txhawm rau txhim kho kev sib raug zoo ntawm silica hais nrog PET thiab txhawb nqa lawv cov dispersion hauv cov txheej txheem PET polymerization, cov tshuaj kho deg (dispersants, coupling agents, thiab lwm yam) yog siv los kho lawv kom txo lawv qhov nro thiab polarity. Nyob rau hauv cov ntaub ntawv no, kev faib ntawm silica hais nyob rau saum npoo ntawm zaj duab xis yuav cuam tshuam rau lub polarity thiab nto nro ntawm cov zaj duab xis nto, thiab tus neeg saib xyuas nto heev yuav tsiv mus nyob rau saum npoo ntawm zaj duab xis, uas ua rau tsis zoo aluminium plating kev ua tau zoo.
