mankhwala

Chonyamulira kapena Chodzaza ndichinthu chopanda tanthauzo pakupanga mankhwala ophera tizilombo. Ntchito yake yayikulu ndikuwonetsetsa kuti mankhwala opangira mankhwala opangira mankhwala akugwiritsidwa ntchito ndikufalitsa zomwe zimagwiritsidwa ntchito popanga mankhwalawa ndi owonjezera ma surfactants ndi zinthu zina. Chosakanitsa yunifolomu chimapangidwa kuti pakhale kuwonekera komanso kuzizira kwa malonda; nthawi yomweyo, magwiridwe antchito amakula bwino, ndipo atha kugwiritsidwa ntchito atasungunuka m'madzi mosamala komanso mosavuta.

Diatomaceous lapansi ili ndi dongosolo lapadera komanso mwadongosolo la kapangidwe ka nano-micropore, voliyumu yayikulu ya pore, malo akulu enieni, komanso kuchuluka kwamafuta ambiri. Chifukwa chake, popopera mankhwalawo, mankhwalawo amatha kulowa mosavuta ndikufalikira mu nano-micropores mkati mwaonyamula. Amagawidwa mu diatomite, motero imatenga nthawi yayitali, ndipo zotsatira zake zimakhala bwino kuposa bentonite

Nthawi zambiri, zinthu zokhala ndi mphamvu zotsatsira, monga diatomaceous earth, bentonite, attapulgite, ndi white carbon wakuda, amatchedwa onyamula. Nthawi zambiri amagwiritsidwa ntchito ngati masanjidwewo opanga ufa wokwera kwambiri, ufa wonyowa kapena mapira, ndipo amathanso kugwiritsidwa ntchito ngati ufa wonyowa ndi madzi. Amagwiritsidwa ntchito ngati pobzala pobalalitsa ma granules ndi zinthu zina. Zinthu zokhala ndi otsika kapena apakatikati otsatsa, monga talc, pyrophyllite, dongo (monga kaolin, dongo, ndi zina zambiri) amagwiritsidwa ntchito pokonza ufa wocheperako, granules zamadzi zotayika, mapiritsi omwe amatha kufalikira ndi zinthu zina zotchedwa filler (Filler) kapena kuchepa (Chosokonekera). Zonse "zonyamula" ndi "filler" zimagwiritsidwa ntchito kunyamula kapena kusungunula zosakaniza za mankhwala ophera tizilombo, ndikupatsanso mankhwala opangira mankhwalawa madzi, kufalikira komanso kugwiritsa ntchito bwino.

Gawo lalikulu la diatomaceous lapansi ndi silicon dioxide, ndipo kapangidwe kake ka mankhwala kakhoza kuwonetsedwa ndi SiO2 · nH2O. Ndi mwala wosalala wambiri. Pali mitundu yambiri yapadziko lapansi ya diatomaceous yokhala ndi mawonekedwe osiyanasiyana, monga disc, sieve, ellipse, ndodo, bwato ndi embankment. Onaninso nyemba zowuma ndi makina oonera microscope (SEM). Ili ndi ma micropores ambiri, malo akulu enieni, komanso mphamvu zotsatsira, makamaka zamadzimadzi. Chifukwa chake, chimagwiritsidwa ntchito kwambiri ngati chonyamulira popanga ufa wokwanira kunyowa wambiri ndi utsogoleri wa ufa, makamaka woyenera kukonza mankhwala ophera tizilombo opangira madzi ndi mankhwala osungunuka otsika omwe amagwiritsidwa ntchito popanga ufa wokwanira kunyowa ndi ma granules osungunuka ndi madzi; kapena Yogwirizana ndi onyamula okhala ndi mphamvu zazing'ono zakutsatsa, monga chonyamulira chamagulu amtundu wonyowa ndi timagulu tomwe timatulutsa madzi kuti tiwonetsetse kukonzekera kwa kukonzekera.
