Qhov sib txawv tseem ceeb ntawm nanomaterials thiab bulk cov ntaub ntawv yog tias cov nanomaterials muaj lawv qhov loj me hauv 1-100 nm ntau yam tsawg kawg nkaus hauv ib qhov ntev whereas cov ntaub ntawv loj muaj lawv qhov loj dua 100 nm hauv txhua qhov ntev.
Nanomaterials thiab bulk cov ntaub ntawv yog ob hom loj ntawm cov khoom. Lawv txawv ntawm ib leeg raws li lawv qhov loj me. Ntxiv mus, lawv muaj cov tshuaj lom neeg thiab lub cev sib txawv. Yog li ntawd, lawv muaj ntau daim ntawv thov thiab.
Nanomaterials yog dab tsi?
Nanomaterials yog cov khoom uas muaj lawv qhov loj hauv 1-100 nm ntau yam tsawg kawg hauv ib qhov ntev. Muaj ntau qhov chaw ntawm cov khoom no. Piv txwv li, peb tuaj yeem tau txais cov khoom no raws li cov khoom siv hluav taws xob, ua cov khoom sib tsoo thiab los ntawm cov khoom siv ntuj tsim. Muaj ntau hom nanomaterials;
- Nanomaterials - Lawv muaj tag nrho lawv qhov ntev hauv 1-100 nm nplai.
- Ib qhov loj me nanostructure - ib qhov ntev muaj nws qhov loj me sab nraum nanoscale.
- Ob-dimensional nanostructures - ob qhov ntev tsis nyob hauv nanoscale.
- Bulk nanostructures - tsis muaj qhov ntev nyob hauv nanoscale (tag nrho cov siab tshaj 100 nm).
Daim duab 01: Kev sib piv ntawm Nanomaterials thiab Bulk Materials
Muaj ntau daim ntawv thov ntawm cov ntaub ntawv no nyob rau hauv ntau yam kev tsim khoom, kev siv kho mob, ntau yam khoom xws li xim, lim, lubricant additives, thiab lwm yam. Piv txwv li, nanozymes yog cov khoom uas yog nanoparticles, thiab lawv muaj cov yam ntxwv zoo li enzyme.
Cov Khoom Siv Loj yog dab tsi?
Cov ntaub ntawv ntau yog cov khoom uas muaj lawv qhov loj dua 100 nm hauv txhua qhov loj me. Feem ntau ntawm cov sij hawm, peb siv lo lus no thiaj li hu ua ib yam khoom uas yog granular los yog lumpy thiab muaj nyob rau hauv dawb-flowing daim ntawv. peb siv cov nplej loj thiab cov nplej faib rau hauv cov khoom siv no. Ntxiv mus, peb tuaj yeem piav qhia lawv cov peev txheej, cov ntsiab lus noo noo, kub, thiab lwm yam. Muaj ob yam khoom siv no:
- Cohesionless, free-flowing bulk khoom
- Cov ntaub ntawv sib xyaw ua ke
Cov ntaub ntawv ntau suav nrog cov khoom peb siv hauv kev tsim kho; plaster, xuab zeb, gravel, cement, thiab lwm yam. Tsis tas li ntawd, nws suav nrog cov khoom siv raw uas peb siv rau ntau yam lag luam xws li ore, slag, ntsev, thiab lwm yam. Tsis tas li ntawd, qhov no suav nrog cov khoom siv hmoov xws li pigments, fillers, granules, pellets., lwm.
Qhov txawv ntawm Nanomaterials thiab Bulk Materials yog dab tsi?
Nanomaterials yog cov khoom uas muaj lawv qhov loj hauv 1-100 nm ntau yam tsawg kawg hauv ib qhov ntev. Peb tsis tuaj yeem pom lawv cov khoom los ntawm qhov muag liab qab. Ntxiv mus, piv txwv ntawm cov ntaub ntawv no muaj xws li nanozymes, titanium dioxide nanoparticles, graphene, thiab lwm yam. Cov ntaub ntawv loj yog cov khoom uas muaj lawv qhov loj tshaj 100 nm nyob rau hauv tag nrho qhov ntev. Peb tuaj yeem pom lawv cov khoom los ntawm qhov muag liab qab. Cov piv txwv ntawm cov ntaub ntawv no muaj xws li plaster, xuab zeb, gravel, cement, ore, slag, ntsev, thiab lwm yam. Cov nram qab no infographic nthuav qhia qhov txawv ntawm nanomaterials thiab bulk cov ntaub ntawv nyob rau hauv daim ntawv.
Summary – Nanomaterials vs Bulk Materials
Nanomaterials tsis pom qhov muag liab qab. Tab sis cov ntaub ntawv loj, peb tuaj yeem pom lawv cov khoom. Qhov txawv ntawm nanomaterials thiab bulk cov ntaub ntawv yog hais tias nanomaterials muaj lawv loj nyob rau hauv 1-100 nm ntau yam tsawg kawg nkaus nyob rau hauv ib qhov ntev whereas bulk cov ntaub ntawv muaj lawv loj tshaj 100 nm nyob rau hauv tag nrho cov qhov ntev.
