Zingaphi Ozaziyo Ngesinyithi esineziporo?

Ngaba ukhe wazibuza ukuba isihluzi sekofu sibamba njani umhlaba ngelixa sivumela ulwelo ukuba ludlule,

okanye zisebenza njani izixhobo zokuthintela isandi? Impendulo inokufumaneka kwiklasi enomdla

imathiriyeli -iintsimbi ezinamaqhekeza.

Iintsimbi ezinamabhodloyile nto kanye zivakala ngayo: iintsimbi ezinemingxuma emincinane okanye imingxuma.

Ezi zakhiwo zibonakala zilula zivula ihlabathi lamathuba kwizicelo ezahlukeneyo zemizi-mveliso.

Indibaniselwano yabo ekhethekileyo yamandla esinyithi kunye nommandla ophezulu owenziwe ngama-pores

izenza zisebenziseke kakhulu. Masizazi iinkcukacha ezithe kratya malunga neentsimbi ezinemingxuma.

Ukuqonda Amandla eentsimbi zePorous

Makhe sihlolisise i-nitty-gritty yesinyithi esinentunjana kwaye siqonde ukuba yintoni ebangela ukuba zibaluleke kangaka kwizicelo zemizi-mveliso.

Ukuchaza iintsimbi ezinembobo:

Kwisiseko sayo, isinyithi esine-porous sisinyithi esinenethiwekhi ye-pores edibeneyo okanye eyodwa kwisakhiwo sayo. Ezi pores zinokuhluka kakhulu ngobukhulu, imilo, kunye nokusabalalisa, kuxhomekeke kwiipropati ezifunwayo kunye nenkqubo yokuvelisa.

IiPropathi eziPhambili zeeMetal eziMbhobho:

* I-Porosity ephezulu:

Isici esichazayo - umthamo omkhulu wendawo engenanto ngaphakathi kwentsimbi ngokwayo. Le porosity ivumela ulwelo okanye iigesi ukuba zidlule ngelixa isakhiwo sesinyithi sihlala siqinile.

* Umlinganiselo wamandla aphezulu kubunzima:

Nangona i-voids, isinyithi esine-porous sinokumangalisa ngokumangalisayo kwaye silula. Oku kubenza balungele izicelo apho ubunzima buyinkxalabo.

* Indawo enkulu yoMphezulu:

Uthungelwano oluntsonkothileyo lweepores ludala indawo enkulu yomhlaba ngaphakathi komthamo omncinci. Oku kunenzuzo kwiinkqubo ezifana nokuhluzwa, i-adsorption, kunye ne-catalysis.

Kutheni le nto amashishini ethanda iintsimbi ezinamanzi:

Iipropathi ezikhethekileyo zeentsimbi ezinamaqhekeza zibenza bafuneke kakhulu kwizicelo ezahlukeneyo zemizi-mveliso. Nanku umboniso wesizathu sokuba:

Uhluzo:

Ubungakanani be-pore obulawulwayo buvumela ukwahlula ngokufanelekileyo kwezinto ezifunwayo kwiinqununu ezingafunekiyo. Oku kubalulekile kwiinkqubo ezifana nokucoca ulwelo, iigesi, kunye nesandi.
