Cov yam ntxwv ntawm nanomaterials tau tso lub hauv paus rau nws daim ntawv thov dav.Siv nanomaterials tshwj xeeb los tiv thaiv ultraviolet, tiv thaiv kev laus, siab zog thiab toughness, zoo electrostatic shielding nyhuv, xim hloov nyhuv thiab antibacterial thiab deodorizing muaj nuj nqi, kev loj hlob thiab kev npaj ntawm tshiab hom tsheb coatings, nano-composite tsheb lub cev, nano- cav thiab nano-automotive lubricants, thiab tso pa purifiers muaj dav daim ntawv thov thiab kev loj hlob zeem muag.

Thaum cov ntaub ntawv raug tswj mus rau nanoscale, lawv tsis tsuas yog lub teeb, hluav taws xob, hluav taws xob, hluav taws xob, thiab cov hlau nplaum hloov, tab sis kuj muaj ntau yam tshiab xws li hluav taws xob, kev nqus.Qhov no yog vim qhov kev ua haujlwm saum npoo ntawm nanomaterials nce nrog cov khoom me me ntawm cov khoom.Nanomaterials tuaj yeem pom nyob rau hauv ntau qhov chaw ntawm lub tsheb, xws li chassis, log tsheb lossis lub cev tsheb.Txog tam sim no, yuav ua li cas siv nanotechnology kom ua tiav txoj kev loj hlob sai ntawm cov tsheb tseem yog ib qho teeb meem tseem ceeb tshaj plaws hauv kev lag luam tsheb.

Daim ntawv thov tseem ceeb ntawm nanomaterials hauv kev tshawb fawb tsheb thiab kev loj hlob

1.Automotive txheej

Daim ntawv thov ntawm nanotechnology nyob rau hauv automotive txheej yuav muab faib ua ntau yam kev qhia, xws li nano topcoats, kev sib tsoo-xim-hloov txheej, anti-stone-strike coatings, anti-static txheej, thiab deodorizing txheej.

(1) Tsheb topcoat

Lub topcoat yog ib qho kev ntsuam xyuas ntawm qhov zoo ntawm lub tsheb.Lub tsheb topcoat zoo yuav tsum tsis yog tsuas yog muaj cov khoom zoo nkauj zoo nkauj xwb, tab sis kuj muaj cov kav ntev, uas yog, nws yuav tsum muaj peev xwm tiv taus ultraviolet rays, noo noo, acid los nag thiab tiv thaiv khawb thiab lwm yam khoom. 

Nyob rau hauv nano topcoats, nanoparticles yog dispersed nyob rau hauv lub organic polymer moj khaum, ua raws li load-bearing fillers, interacting nrog lub moj khaum cov ntaub ntawv thiab pab txhim kho lub toughness thiab lwm yam mechanical zog ntawm cov ntaub ntawv.Cov kev tshawb fawb pom tau tias dispersing 10% ntawmnano TiO2cov khoom hauv cov resin tuaj yeem txhim kho nws cov khoom siv kho tshuab, tshwj xeeb tshaj yog khawb tsis kam.Thaum nano kaolin siv los ua muab tub lim, cov khoom sib xyaw tsis yog pob tshab xwb, tab sis kuj muaj cov yam ntxwv ntawm absorbing ultraviolet rays thiab siab dua thermal stability.

Tsis tas li ntawd, nanomaterials kuj muaj cov nyhuv hloov xim nrog lub kaum sab xis.Ntxiv nano titanium dioxide (TiO2) rau cov xim hlau glitter tiav ntawm lub tsheb tuaj yeem ua rau cov txheej txheem tsim cov xim nplua nuj thiab tsis tuaj yeem tshwm sim.Thaum nanopowders thiab flash aluminium hmoov los yog mica pearlescent hmoov pigment siv nyob rau hauv txheej txheej, lawv tuaj yeem cuam tshuam xiav opalescence hauv thaj chaw photometric ntawm lub teeb-emitting cheeb tsam ntawm txheej txheej, yog li ua kom tag nrho cov xim ntawm cov xim. hlau tiav thiab ua kom pom cov nyhuv tshwj xeeb.

Ntxiv Nano TiO2 rau Automotive Metallic Glitter Finishes-Collision xim hloov xim

Tam sim no, cov xim ntawm lub tsheb tsis hloov pauv loj heev thaum nws ntsib kev sib tsoo, thiab nws yog ib qho yooj yim kom tawm hauv qhov kev puas tsuaj vim tsis muaj kev puas tsuaj sab hauv.Sab hauv ntawm cov xim muaj cov microcapsules uas muaj cov xim dyes, uas yuav tawg thaum raug rau lub zog sab nraud, ua rau cov xim ntawm qhov cuam tshuam hloov tam sim ntawd kom cov neeg mob siab rau.

(2) Anti-pob zeb chipping txheej

Lub tsheb lub cev yog qhov ze tshaj plaws rau hauv av, thiab feem ntau cuam tshuam los ntawm ntau yam sib tsoo pob zeb thiab pob zeb tawg, yog li nws yuav tsum tau siv cov txheej txheem tiv thaiv nrog kev tiv thaiv pob zeb.Ntxiv nano alumina (Al2O3), nano silica (SiO2) thiab lwm yam hmoov rau automotive txheej tuaj yeem txhim kho lub zog saum npoo ntawm txheej, txhim kho hnav tsis kam, thiab txo qhov kev puas tsuaj los ntawm pob zeb rau lub tsheb lub cev.

(3) Antistatic txheej

Txij li thaum hluav taws xob zoo li qub tuaj yeem ua rau muaj teeb meem ntau, kev txhim kho thiab kev siv cov txheej txheem antistatic rau automotive tha xim sab hauv cov txheej txheem thiab cov khoom yas tau nce zuj zus.Ib lub tuam txhab Nyij Pooj tau tsim cov khoom tawg-dawb antistatic pob tshab txheej rau automotive yas qhov chaw.Hauv Teb Chaws Asmeskas, nanomaterials xws li SiO2 thiab TiO2 tuaj yeem ua ke nrog cov resins li electrostatic shielding coatings.

(4) Deodorant xim

Cov tsheb tshiab feem ntau muaj cov ntxhiab tsw ntxhiab, feem ntau yog cov tshuaj tsis haum tshuaj muaj nyob hauv cov khoom siv ntxiv hauv cov khoom siv kho kom zoo nkauj tsheb.Nanomaterials muaj cov tshuaj tua kab mob muaj zog heev, deodorizing, adsorption thiab lwm yam haujlwm, yog li qee cov nanoparticles tuaj yeem siv los ua cov khoom thauj mus rau adsorb cuam tshuam cov kab mob ions, yog li tsim cov deodorizing txheej kom ua tiav kom tsis muaj menyuam thiab cov hom phiaj tiv thaiv kab mob.

2. Tsheb xim

Thaum lub tsheb xim tev thiab muaj hnub nyoog, nws yuav ua rau muaj kev zoo nkauj ntawm lub tsheb, thiab kev laus yog qhov nyuaj rau tswj.Muaj ntau yam uas cuam tshuam rau kev laus ntawm cov xim tsheb, thiab qhov tseem ceeb tshaj plaws yuav tsum muaj nyob rau hauv lub hnub ci ultraviolet.

Ultraviolet rays tuaj yeem yooj yim ua rau cov saw hlau molecular ntawm cov khoom tawg, uas yuav ua rau cov khoom muaj hnub nyoog, yog li ntawd cov polymer plastics thiab cov txheej txheem organic muaj feem xyuam rau kev laus.Vim tias uv rays yuav ua rau cov yeeb yaj kiab tsim hauv cov txheej txheem, uas yog, cov saw hlau molecular, ua rau tawg, tsim cov dawb radicals heev, uas yuav ua rau tag nrho cov yeeb yaj kiab tsim cov khoom siv molecular rau decompose, thiab thaum kawg ua rau txheej txheej. hnub nyoog thiab deteriorate.

Rau cov organic coatings, vim ultraviolet rays yog heev txhoj puab heev, yog hais tias lawv muaj peev xwm zam tau, cov laus tiv thaiv ntawm ci xim yuav zoo heev.Tam sim no, cov khoom siv nrog UV tiv thaiv feem ntau yog nano TIO2 hmoov, uas tiv thaiv UV feem ntau los ntawm kev tawg.Nws tuaj yeem txiav txim siab los ntawm kev xav tias qhov loj me ntawm cov khoom yog nyob nruab nrab ntawm 65 thiab 130 nm, uas muaj qhov zoo tshaj plaws ntawm UV tawg..

3. Auto Tyre

Hauv kev tsim cov tsheb log tsheb, cov hmoov xws li cov pa roj carbon dub thiab silica xav tau los ua cov khoom siv ntxiv thiab cov accelerators rau roj hmab.Cov pa roj carbon dub yog lub ntsiab tseem ceeb ntawm cov roj hmab.Feem ntau hais lus, qhov me me ntawm qhov me me thiab qhov loj ntawm thaj chaw tshwj xeeb, qhov zoo dua qhov kev ua tau zoo ntawm carbon dub.Ntxiv mus, nanostructured carbon dub, uas yog siv nyob rau hauv lub log tsheb treads, muaj tsawg dov tsis kam, siab hnav tsis kam thiab ntub skid kuj piv nrog cov thawj cov pa roj carbon dub, thiab yog ib tug pheej yig high-kev ua tau zoo carbon dub rau log tsheb treads.

Nano Silicayog ib puag ncig tus phooj ywg additive nrog kev ua tau zoo heev.Nws muaj super adhesion, tsim kua muag tsis kam, kub tsis kam thiab tiv thaiv kev laus, thiab tuaj yeem txhim kho cov kev ua haujlwm ntub dej thiab ntub kev ua haujlwm ntawm cov log tsheb.Silica yog siv rau hauv cov khoom siv roj hmab xim los hloov cov pa roj carbon dub rau kev txhawb nqa kom tau raws li cov kev xav tau ntawm cov khoom siv dawb lossis cov khoom translucent.Nyob rau tib lub sijhawm, nws tseem tuaj yeem hloov tau ib feem ntawm cov pa roj carbon dub hauv cov khoom siv roj hmab dub kom tau txais cov khoom siv roj hmab zoo, xws li cov log tsheb tawm, cov log tsheb engineering, cov log tsheb radial, thiab lwm yam. Qhov me me ntawm cov khoom siv roj hmab, ntau dua. nws cov dej num nto thiab siab dua cov ntsiab lus binder.Feem ntau siv silica particle loj li ntawm 1 txog 110 nm.
