1. Sib cuag lub kaum sab xis thiab qhov ntsuas hluav taws xob (Wettability Basics)
- Static Contact Angle: Ntsuas siv dej thiab diiodomethane (los yog hexadecane) cais. Lub kaum sab xis ntawm dej yog feem ntau siab dua 110 °. Lub kaum sab xis ntawm cov roj ntau dua qhia tias muaj zog tiv thaiv cov roj fouling thiab adhesion.
- Rolling / Sliding Angle: Lub kaum sab xis ntawm lub tee dej ntawm ib lub ntim tshwj xeeb pib xaub tawm ntawm qhov chaw maj mam qaij. Lub kaum sab xis me me qhia tau tias muaj kev tiv thaiv zoo dua thiab yooj yim-tu khoom, uas yog qhov tseem ceeb tshwj xeeb rau kev kuaj roj.
- Surface Free Energy Calculation: Cov polar thiab dispersive Cheebtsam yog xam siv txoj kev xws li Owens-Wendt. Qhov qis zog saum npoo av (PTFE tus nqi zoo tshaj yog kwv yees li 18-20 mN / m), qhov nyuaj dua nws yog rau cov khoom paug thiab cov kua dej kom ntub thiab sib kis.
2. Kev ntsuam xyuas cov cuab yeej los tiv thaiv cov khoom (Peel Force / Adhesion Force)
- Standard Pressure-Sensitive Tape Peel Test: Ib daim kab xev uas tau teev tseg (xws li, 3M 810 lossis ib daim kab xev uas raug xaiv) yog nias rau ntawm PTFE daim kab xev nplaum uas siv tus qauv rau cov menyuam. Tom qab sab laug los sawv ntsug rau lub sijhawm teem tseg, 180 ° tev kuaj yog ua nrog lub tshuab ntsuas tensile (saib GB / T 2792). Qhov qis dua lub tev quab yuam, qhov muaj zog tiv thaiv cov cuab yeej, nrog tus nqi zoo tshaj hauv qab 0.1 N / 25 mm.
- Kev Ntsuas Nruab Nrab Tshwj Xeeb: Cov khoom nplaum uas tau ntsib hauv kev siv, xws li asphalt, daim ntawv nplaum rau tus kheej, lossis cov nplaum kub yaj, yog siv los ntsuas qhov quab yuam uas yuav tsum tau tev tawm ntawm qhov chaw.
3. Simulated Test rau roj kuj thiab yooj yim Cleanability
- Roj Stains Sliding/Residue Method: Ib txheej ntawm cov roj cav, roj ua noj, lossis roj pleev xim yog siv rau hauv cov qauv tilted ntawm ib lub kaum ntse ntse. Qhov zawv zawg qhov ntev ntawm cov roj stain los yog qhov feem pua ntawm qhov chaw seem ntawm qhov chaw yog ntsuas.
- Quantitative Wiping Cleaning Efficiency:
- Cov txheej txheem tsim av (kev sib xyaw ntawm cov roj carbon dub, roj, thiab oleic acid) yog sib npaug thiab qhuav. Ib daim ntaub uas tsis muaj lint uas ntub dej thiab cov tshuaj ntxuav tes tsis zoo yog siv los so rov qab thiab tawm mus rau tus naj npawb ntawm cov voj voog nyob rau hauv ib qho kev teeb tsa.
- Cov neeg tsim khoom ntawm PTFE-coated fiberglass npuag hauv Jiangsu feem ntau siv lub ntsuas xim sib txawv los ntsuas qhov sib txawv xim ΔE ua ntej thiab tom qab so, lossis ntsuas kev tu kom zoo los ntawm cov av seem (gravimetric method). Ib qho me me ΔE thiab qis dua qhov hnyav qhia tau zoo dua kev ua haujlwm tu yooj yim. Tus nqi rov qab ntawm lub kaum sab xis ntawm qhov chaw ntxuav kuj tuaj yeem ntsuas.
- Kev Ntsuas Kev Ntsuas nrawm nrog Oily Marker: Cov cim oily yog siv los kos kab ntawm qhov chaw. Saib xyuas seb tus number case yuav txo qis mus rau hauv cov tee dej tsis tu ncua lossis sib kis tsis tu ncua, thiab tom qab ntawd so nrog daim ntaub qhuav kom pom tias nws yooj yim tshem tawm. Nthuav shrinkage thiab tshem tawm yooj yim qhia tau hais tias zoo anti-fouling thiab yooj yim-tu khoom.
4. Kev Tiv Thaiv-Dust thiab Anti-Particle Adhesion Test
- Txoj Kev Plua Plav: Cov qauv kuaj plua plav (piv txwv li ISO 12103-1 A2 cov plua plav zoo) raug tso cai nyob rau hauv qhov chaw ntawm vertically lossis 45 °-inclined qauv saum npoo hauv chav kaw. Tom qab maj mam tapping los yog tshuab nrog cov pa roj tsawg, qhov seem plua plav cheeb tsam / huab hwm coj yog ntsuas siv cov duab tsom xam lossis txoj kev gravimetric.
- Kev tshem tawm plua plav los ntawm txoj kev Airflow: Cov plua plav uas paub txog yog sib npaug ntawm cov qauv kab rov tav. Tus nqi ntws ntawm cov kwj nitrogen yog maj mam nce, thiab qhov tsawg kawg nkaus airflow tshaj tawm yuav tsum tau ua kom tag nrho cov plua plav tawm. Qhov qis dua qhov nrawm, qhov zoo dua cov khoom tiv thaiv plua plav adhesion.
- Kev ntsuam xyuas ntawm Electrostatic Adsorption Effects: Txij li thaum plua plav adsorption feem ntau ua rau cov hluav taws xob zoo li qub, lub sij hawm tiv thaiv thiab electrostatic decay yuav tsum tau sim kom paub qhov txawv ntawm cov nyhuv yog vim muaj tshuaj tiv thaiv los yog electrostatic adsorption.
5. Txhawb Kev Ntsuas Kev Ntsuas
- Tom qab qhov kub thiab txias (piv txwv li, ntawm 260 ° C lossis 300 ° C) los yog kev sib txhuam / hnav (Taber abrasion), lub kaum sab xis saum toj no, tev quab yuam, thiab kev ntsuam xyuas kev ua kom huv tau rov qab los xyuas kom meej tias kev ua tau zoo tsis txo qis thaum siv mus ntev.
