Chithovu chamkuwa chochuluka kwambiri ndi mtundu watsopano wazinthu. Ngakhale kuti yakhala ikugwiritsidwa ntchito kwambiri m’mafakitale ankhondo ndi mabatire, kugwiritsiridwa ntchito kwake kofala m’mafakitale ena kwangoyamba kumene, ndipo anthu sadziwa mozama mokwanira. M'munsimu ndi chidule chachidule cha makhalidwe a ultra-thick mkuwa thovu. Zofunikira:

1. High porosity: pafupifupi mawonekedwe owonekera bwino ndi porosity yoposa 98%, monga zosefera, kutsika kwapansi kumakhala kochepa komanso kuthamanga kwapamwamba;

2. Malo akuluakulu apadera: pamtundu wofanana, ali ndi malo akuluakulu enieni poyerekeza ndi zipangizo zina za porous;

3. Mkulu wa porosity ndi mawonekedwe a pore yunifolomu: porosity imafika kupitirira 95%, ndi mawonekedwe atatu-dimensional porous ndi mandala, ndipo ali ndi mphamvu zabwino zachitsulo, voliyumu yofanana, kulemera kwa zinthu zopepuka, ndi kulolerana kwakukulu panthawi yomweyo. Mayamwidwe abwino amawu, kuyamwa mphamvu, ntchito yotchinga yamagetsi;

4. Imakhala ndi ntchito yachitsulo: thovu lamkuwa lakuda kwambiri limatha kupangidwa ndi faifi tambala, mkuwa, chitsulo, kapena aloyi. Magawo osiyanasiyana ali ndi ntchito zosiyanasiyana zachitsulo, monga zosawotcha moto, zopanda vuto, zotsalira zosagwa, zobwezerezedwanso, zopangira matenthedwe, ndi zina zambiri.

5. Ikhoza kuwotcherera, kudula, kupukuta, kukulunga ndi kukonza makina. Panthawi imodzimodziyo, zinthu zachitsulo zimatha kubwezeretsedwanso, zomwe zimapindulitsa kuteteza chilengedwe ndikusunga ndalama.
