Yintoni usetyenziso lweTiO2 kwiConcrete?

I-Titanium dioxide (i-TiO2) iyongezwa kwizinto ezininzi ezifumana izicelo ezininzi kwiifom zekhonkrithi ngenxa yeempawu zayo ezizodwa.Olunye usetyenziso oluqhelekileyo lwe-TiO2 kwikhonkrithi lubandakanya:

1. Umsebenzi wePhotocatalytic:

I-TiO2 ibonisa umsebenzi we-photocatalytic xa ibonakaliswe kwi-ultraviolet (UV) ukukhanya, okukhokelela ekuthotyweni kwezinto eziphilayo kunye nezinto ezingcolileyo kumphezulu wekhonkrithi.Le propati inenzuzo ngokukodwa ekunciphiseni ukungcoliseka komoya kunye nokuphucula umgangatho womoya kwiindawo zasezidolophini.Imiphezulu yekhonkrithi ene-TiO2 inokunceda ukudiliza izinto ezingcolisa umoya ezifana ne-nitrogen oxides (NOx) kunye ne-volatile organic compounds (VOCs), igalelo kwiindawo ezicocekileyo nezinempilo zasedolophini.

2. Ukuzicoca ngokwako imiphezulu:

I-TiO2 nanoparticles efakwe kwikhonkrithi inokudala iindawo zokuzicoca ezigxotha ukungcola, ukungcola, kunye nezinto eziphilayo.Xa isebenze ngokukhanya kwelanga, i-TiO2 nanoparticles ivelisa iintlobo ze-oksijini ezisebenzayo (ROS) ezixuba kwaye zibolise izinto eziphilayo phezu kwekhonkrithi.Lo mphumo wokuzicoca unceda ukugcina ukubonakala kobuhle kunye nokucoceka kwezakhiwo eziphathekayo, ukunciphisa imfuno yokucoca rhoqo kunye nokugcinwa.

3. Ukuphuculwa koKuhlala ixesha elide:

Ukongezwa kwee-nanoparticles ze-TiO2 kwikhonkrithi kunokunyusa ukuqina kwayo kunye nokuchasana nokuthotywa kokusingqongileyo.I-TiO2 isebenza njenge-photocatalyst ekhuthaza ukubola kwezinto ezingcolileyo eziphilayo, ukunciphisa ukuqokelela kwezinto ezingcolileyo ebusweni bekhonkrithi.Oku, kwakhona, kunceda ukunciphisa imiphumo yemozulu, ibala, kunye nokukhula kwe-microbial, ukwandisa ubomi benkonzo yezakhiwo eziphathekayo ezivezwe kwiimeko zangaphandle.

4. Iinkcazelo ngeempawu:

Iinanoparticles ze-TiO2 zinokunikezela ngeempawu ezibonisayo kumphezulu obambekayo, ukunciphisa ukufunxa ubushushu kunye nokunciphisa isiphumo sesiqithi sobushushu sasedolophini.Ikhonkrithi enombala okhanyayo equlethe amasuntswana e-TiO2 ibonakalisa ukukhanya kwelanga ngakumbi kwaye ifunxa ubushushu obuncinane xa kuthelekiswa nekhonkrithi eqhelekileyo, okukhokelela kubushushu obuphantsi komhlaba kunye nokunciphisa ukusetyenziswa kwamandla okupholisa kwiindawo zasezidolophini.Oku kwenza ikhonkrithi elungisiweyo ye-TiO2 ilungele izicelo ezifana neepavumente, iindledlana zeenyawo, kunye neepavumente zasezidolophini.

5. IiPropati ezichasene neMicrobial:

I-TiO2 i-nanoparticles ibonakaliswe ukuba ibonise iimpawu ze-antimicrobial, inqanda ukukhula kweebhaktheriya, i-fungi, kunye ne-algae kwiindawo eziphathekayo.Le mpembelelo ye-antimicrobial inceda ukuthintela ukubunjwa kwe-biofilms, amabala, kunye nevumba kwizakhiwo zekhonkrithi, ngokukodwa kwiindawo ezifumileyo nezimanzi apho ukukhula kwe-microbial kuxhaphake.Ikhonkrithi elungisiweyo ye-TiO2 ke ngoko inokuba negalelo ekuphuculweni kwezempilo nogutyulo kwiindawo ezifana nezibhedlele, iilabhoratri, kunye neendawo zokulungisa ukutya.

Isiphelo:

Ukuququmbela, i-Titanium dioxide (TiO2) isebenza ngeenjongo ezininzi kwiifom zekhonkrithi, inikezela ngeenzuzo ezifana nomsebenzi we-photocatalytic, iipropati zokuzihlambulula, ukuphuculwa kokuqina, indawo ecacileyo, kunye nemiphumo ye-antimicrobial.Ngokubandakanya i-TiO2 nanoparticles kwimixube yekhonkrithi, iinjineli kunye nabakhi bezakhiwo banokuphucula ukusebenza, ixesha elide, kunye nokuzinza kwezakhiwo zekhonkrithi ngelixa zijongene nokukhathazeka kokusingqongileyo kunye nempilo.Njengoko uphando kunye nophuhliso lwe-nanotechnology luqhubela phambili, ukusetyenziswa kwe-TiO2 kwikhonkrithi kulindeleke ukuba kudlale indima ebaluleke kakhulu kushishino lokwakha, ukunika izisombululo ezitsha zeziseko zophuhliso ezidolophini kunye nokuzinza kokusingqongileyo.
