Nws cuam tshuam nrog nano fibers ntawm qib atomic thiab molecular thiaj li yuav tweak lawv cov khoom. Cov cuab yeej tshiab no tuaj yeem ua rau muaj qhov tsis txaus ntseeg khaub ncaws xws li dej-resistant thiab av-dawb khaub ncaws , tsw ntxhiab tsw-tsawg thom khwm, thiab ntse khaub ncaws uas tuaj yeem ua haujlwm tswj kev nyab xeeb rau koj.
Tsuas yog li ntawd, nanotechnology siv li cas hauv khaub ncaws?
Nanoparticles ntawm silica incorporated rau hauv weave ntawm ib daim ntaub los yog sprayed rau nws nto tsim ib txheej uas repels dej thiab stain-ua kua. Lub kaum sab xis thiab roughness ntawm silica txheej tsim kom muaj qhov nro txaus los xyuas kom meej tias cov kua tsim cov hlaws uas yob tawm ntawm cov ntaub es tsis txhob ntub rau hauv nws.
Tsis tas li ntawd, nano ntaub ua li cas? Nanotechnology Npuag Cov txheej txheem Nanotechnology ntaub tuaj yeem yog ua siv ntau cov txheej txheem sib txawv. Ib qho ntawm cov txheej txheem no hu ua Sol-gel thiab nws immerses ntaub nyob rau hauv ib tug gel tov rau deposit nanoparticles rau hauv lub khoom . Lwm cov txheej txheem siv plasma los tsim nanotechnology ntaub.
Tsis tas li ntawd, Nano ntaub siv rau dab tsi?
Lub stain repellent ntaub los ntawm Nano -Tex hu ua, Nano - Saib xyuas. Cov Nano - Saib xyuas ntaub siv billions ntawm cov fibers me me, txhua qhov ntev txog 10 nanometers, kos rau hauv cov ntaub ntawv ib txwm muaj xws li paj rwb lossis linen. Cov fibers (hu ua "nanowhiskers") yog cov dej tsis muaj dej thiab ua kom cov ntom ntom ntom ntom ntom ntom ntaub.
Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm nanotechnology?
Nanotechnology muab lub peev xwm rau cov khoos phis tawj tshiab thiab nrawm dua, ua haujlwm tau zoo dua zog qhov chaw thiab kev kho mob cawm txoj sia. Tej yam tsis zoo muaj xws li kev cuam tshuam nyiaj txiag thiab kev hem thawj rau kev ruaj ntseg , kev ceev ntiag tug, kev noj qab haus huv thiab ib puag ncig.

Cov khaub ncaws zoo li cas koj yuav tsum hnav rau hauv hav zoov temperate deciduous?
Hom khaub ncaws koj yuav tsum hnav yog nyob ntawm lub caij nyoog. Nyob rau lub caij ntuj no, nws yog qhov zoo tshaj plaws hnav khaub ncaws hnyav xws li lub tsho lossis lub tsho pullover. Nyob rau lub caij ntuj sov, nws tuaj yeem kub heev, yog li nws raug nquahu kom hnav khaub ncaws sib zog xws li T-shirt lossis luv
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom loj tshwm sim ntawm koj cov khaub ncaws?
Tam sim ntawd yuav siv dab tsi yog tias koj cov khaub ncaws raug hluav taws lossis yog tias muaj tshuaj lom ntau tshwm sim ntawm koj cov khaub ncaws? Koj mus ncaj qha rau da dej kev nyab xeeb thiab sawb ntawm tag nrho koj cov khaub ncaws
Thaum tus ncaws pob ncaws pob lub pob nrawm?
Thaum peb ncaws pob, lub zog peb siv rau nws ua rau nws nrawm nrawm ntawm 0 mus rau qhov ceev ntawm kaum ob kilometers ib teev. Thaum lub pob tso tawm ntawm ko taw, nws pib decelerate (tsis zoo acceleration) vim yog lub zog ntawm kev sib txhuam uas yog exerted rau nws (raws li peb tau pom nyob rau hauv cov piv txwv yav dhau los)
Dab tsi yog qhov zoo pH nruab nrab nqus tsev ntxhua khaub ncaws?
Mild Dish Soap: pH 7 mus rau 8 (Neutral Cleaner) Qhov no ua rau cov tshuaj ntxuav tais diav zoo meej rau kev tu txhua hnub. Feem ntau cov chaw yuav tsis raug puas tsuaj los ntawm cov tshuaj ntxuav tais diav, thiab muaj ntau qhov chaw nws tuaj yeem siv ntxiv rau hauv chav ua noj dab dej
Nws siv zog npaum li cas los ncaws pob ncaws pob?
Yog li thaum cov kws tshaj lij xa cov pob ntawm 30 meters ib ob thiab 1,200 phaus ntawm lub zog, tus neeg laus nruab nrab xa pob ntawm ib ncig ntawm 25 meters ib ob raws li kev ncaws pob ntawm 1,000 phaus ntawm lub zog, thaum cov tub ntxhais hluas nruab nrab tsuas tuaj yeem sau lub pob. ceev ntawm 14.9 meters ib ob, qhia tsuas yog 600 phaus
