Ibyuma bifata ifuro bifite ibipimo bitanu byingenzi:

1. Substrate yicyuma, ni ukuvuga, ibikoresho byuma bikozwe mubyuma bikozwe mubyuma bikozwemo, birimo nikel ifuro ifuro, umuringa, icyuma, icyuma-nikel ivanze, umuringa-nikel, hamwe nubushyuhe bwo hejuru bwibikoresho bitandukanye nka chromizing Tegereza.

2. PPI, Igishinwa numubare wa pore kuri santimetero. Iyi parameter nikintu kidasanzwe cyibikoresho bya sponge. Irerekana umubare wa selile ya sponge inyura kumurongo ugororotse kuri santimetero z'uburebure. Kumenyekanisha intuitive ni uko agaciro ka PPI nini, niko bigaragara cyane hejuru yibintu. Umwobo muto ni, dutanga cyane cyane ibikoresho hagati ya 10PPI na 140PPI. Bitewe no kugabanuka kwa sponge substrate, ibipimo bya PPI byiyongera kuri 10. Urugero, dutanga ibikoresho bifite ibipimo bya PPI nka 10, 20, 30, 40, nibindi, ariko ntidutanga PPI kuri 23, 38 nibindi bikoresho

3. Ubunini, ibikoresho byatanzwe ubu nibikoresho byose byimpapuro, uburebure bwa 0.7mm-25mm.

4. Agace, ubuso ntarengwa bwibintu bisanzwe bisanzwe bitangwa ni 500X500mm.

5. Ubucucike, ubucucike bugabanijwemo ubwinshi nubwinshi bwikibanza. Ubwinshi bwinshi nuburemere bwibintu mubunini butajegajega, nka 1000g / m3, naho ubucucike bwikibanza nuburemere bwibicuruzwa bifite ahantu hateganijwe munsi yubugari bwagenwe, nkuburebure bwa 10mm. Metero kare 1600g; ubucucike bugena imbaraga zibikoresho.

Niba ukeneye kugura ibicuruzwa byibyuma, ugomba kubanza kumenya ibipimo bitanu byavuzwe haruguru, kugirango umenye ibisobanuro byihariye nigiciro cyicyuma.
