Taw qhia: Tus Menace Silent ntawm Cov Tshuaj Txhuam Tshuaj
Cov tsheb niaj hnub yog nthuav tawm ua paug rau ib puag ncig thiab kev siv cov pa tsw qab uas ua tiav lub tsheb ua tiav. Dhau li ntawm txoj kev abriving, tshuaj tsim txom hluav taws xob ua rau lub zog acid (10,5 pH), cov tshuaj orgium ntau rau cov kab ke rau cov khoom siv hluav taws xob ntshiab. Cov tshuaj no ua rau mob oxidation, hydrolysis, thiab macolysis, thiab pob txha caj qaum ua rau muaj kev puas tsuaj rau:
- Etching: Acid Los nag deposits Daim ntawv micro-craters (5-20μm qhov tob) ntawm unclad chaw.
- Swirl cim: harsh dumments sawb tseg tseg tseg tseg cov quav ciab pov tseg, ua rau pleev xim rau kev puas tsuaj.
- Cov khoom siv hluav taws xob tas mus li: Pine SAP (PH 4.2-5.8) thiab noog xa tawm (uric acid cov ntsiab lus ntau dua lossis sib npaug nrog cov xim tsawg dua 48 teev.
Pre-empnitive kev tiv thaiv los nyob rau hauv daim ntawv ntawm lub tsheb tshiabXim tiv thaiv cov yeeb yaj kiab (PPF),uas muab cov khoom siv Nanotechnology nrog polymer science los tsim cov tshuaj lom neeg muaj qhov zoo tshaj plaws uas yog cov khoom sib xyaw ua ke sib xyaw.
Dab tsi ua rau lub tsheb zaj duab xis chav kawm tshuaj lom neeg ua rog?
PPF's Anti-tshuaj lom neeg cov cuab yeej yog vim nws yog ntau-txheej:
1. Thermoplastic Polyurethane (TPU) puag
Molecular muaj pes tsawg leeg: Cov ntxhiab TPU (Dej hardness 80A-95A) nrog interpenetrating polymer tes hauj lwm (IPNs) uas tiv thaiv kev tawm tsam.
Ua rau hydrolysis: nrog carboodiimide additives kom tawm tsam raug rau pH 3-11 (raws li ATM D1308).
2. Anti-paug saum taub hau
Fluorinated sixane Matrix: txo qis saum npoo nro kom tsawg dua lossis sib npaug rau 185 mnc / m), uas nres tar thiab kua muag sticking.
Nano-ceramic txhawb zog: Sio2 / TIO2 hybrid hais (me me rau 50nm) thiab muaj acidic ion nqus.
3. Lub siab-rhiab nplaum (Psa)
Hla Acrylics: UV-kho Adhesives Tswj Bond txoj hlua khi lub zog tom qab cov kev xav hauv cov roj diesel thiab cov kua dej nres.
Tshuaj lom zem tshuaj lom zem & PPF cov kev tiv thaiv kev tiv thaiv
1. Acid Los nag & Kev Nyab Xeeb Deposition
Hem: sulfuric / nitric acid aerosols (PH 2.5) Etch liab qab Cleats los ntawm {2}}. 5μm / xyoo.
TPU PPF Zaj Duab Xis Diam duab: Cov ions nrog amine-ua haujlwm ua haujlwm degrifiers, khaws cov ph-nruab nrab interface.
2. Alkaline Txoj Kev Kho Txoj Kev Sib Tw
Hem: Calcium Magnesium acetate (CMA) cov kev txo nyiaj (ph 2.5) saponify xim binders.
PPF ACTION: Hydrolysis-Proseant Tpu Backbone yuav tsis pub cov pab pawg Eser ntxiv.
3. Kev siv tshuaj lom roj ntsha
Kev hem thawj: Ficus ntoo SAP (proteolytic enzymes + terpenes) nkag rau hauv<2 hours.
PPF ACTION: Tsis muaj-ntxeem nto (RA tsawg dua lossis sib npaug ntawm 0. 1μm) tiv thaiv enzymatic adhesion; Kev fij txheej fij txheej tiv thaiv kom yooj yim kev tshem tawm.
4. Lub cev muaj zog
Hem: Dot 4 nres cov kua dej o cov roj polymers 15% los ntawm ntim.
PPF ACTION: Hla-Txuas Psa Tswjhwm<0.5% swell after 72h immersion
Tshaj kev tiv thaiv: ppf tus kheej kho ntug
Hwm Tsheb PPF zaj duab xis ua ke tus kheej kho cov tes hauj lwm dynamic polymer tes hauj lwm uas tau kho cov tshuaj micro-screen:
● Kev Ua Haujlwm Thermal: Diisocyanate Bonds rov ua haujlwm ntawm 40- tshav ntuj raug), lwv etching cim tsawg dua los yog sib npaug rau 30μm tob.
● Kuab tsis kam: Tsis zoo li waxes, PPF txoj kev kho tus kheej yog tsis raug txwv los ntawm cov tshuaj ntxuav dej cawv.
Cov ntawv pov thawj teeb meem: Xaiv cov yeeb yaj kiab siv tshuaj PPF
Xaus: PPF raws li txoj kev txo qis xeb
Nyob rau hauv lub ntiaj teb uas Urban smog txo lub tsheb pleev xim lub neej los ntawm 40%,Tpu ppfTsis yog tsuas yog lub cev lub cev-nws yog ib qho system Electrochemicalhwm ruaj khov. Los ntawm kev ua tau zoo ntawm kev tiv thaiv kev fij, pH tsis yooj yim, thiab hydrophobic tsis suav, cov tsho tshaj sab saum toj zoo li Leonardo Armorefield Pro muab:
● {{{0 {0}} xyoo lav acid / alkali tua tsis kam.
● {{{0 {0}}. 5μm / xyoo corrosion nkag mus tus nqi (piv rau 3μm / xyoo rau cov xim tsis muaj kev tiv thaiv).
● {5-} feeb kom muaj kev nyab xeeb tshem tawm cov sijhawm luv luv rau caustic cov chaw seem.
Nce siab tshaj kev tiv thaiv nrogLeonardo'sASTM-siv tau PPF qhwv zaj duab xis daws teeb meem-qhov twg polymer science ntsib ib puag ncig lub zog.
