Kushanda musimboti weDiatomite Filter Aid
Basa remafirita aids ndere kushandura iyo aggregation mamiriro ezvimedu, nekudaro kushandura saizi kugoverwa kwezvikamu mufiltrate. Diatomite Sefa Aidare inonyanya kuumbwa nekemikari yakagadzikana SiO2, ine akawanda emukati mamicropores, achigadzira akasiyana siyana akaomarara. Munguva yekusefa, pasi diatomaceous rinotanga kuumba porous filter aid medium (pre coating) pandiro yekusefa. Kana iyo filtrate ichipfuura nemubatsiro wesefa, zvimedu zvakasimba mukumiswa zvinoumba mamiriro akaunganidzwa, uye saizi yekugovera inoshanduka. Izvo zvisina kuchena zvezvimedu zvakakura zvinotorwa uye zvinochengetwa pamusoro pepamusoro pepakati, zvichiita chidimbu chekukura kwekugovera. Vanoramba vachivhara uye kutora zvimedu zvine saizi yakafanana, zvishoma nezvishoma vachigadzira keke resefa rine mamwe pores. Sezvo kusefa kunofambira mberi, tsvina ine diki diki saizi zvishoma nezvishoma inopinda mu porous diatomaceous pasi sefa yerubatsiro yepakati uye inobatwa. Nokuti pasi diatomaceous ine porosity inenge 90% uye yakakura chaiyo nzvimbo, apo zviduku zviduku uye mabhakitiriya anopinda mukati nekunze pores yerubatsiro rwesefa, ivo vanowanzobatwa nekuda kwekushambadza uye zvimwe zvikonzero, izvo zvinogona kuderedza 0.1 μ The kubviswa kwezvimedu zvakanaka uye mabhakitiriya kubva m zvakawana yakanaka yekusefa. Iyo dosage yerubatsiro rwesefa inowanzo 1-10% yehuremu hwakasimba hwakabatwa. Kana iyo dosi yakawandisa, inozokanganisa kuvandudzwa kwekusefa kumhanya.
Kusefa maitiro
Iyo yekusefa mhedzisiro yeDiatomite Filter Aid inonyanya kuwanikwa kuburikidza neanotevera zviito zvitatu:
1. Kuongorora maitiro
Uku ndiko kusefa kwepamusoro, uko kana mvura ichiyerera nepasi diatomaceous, ma pores epasi diatomaceous madiki pane saizi yezvikamu zvetsvina, saka zvimedu zvetsvina hazvigone kupfuura uye zvinobatwa. Mhedzisiro iyi inonzi sieving. Muchokwadi, pamusoro pekeke resefa inogona kutariswa sesefa yepasi ine yakaenzana avhareji pore saizi. Kana iyo dhayamita yezvimedu zvakasimba isiri pasi pe (kana zvishoma zvishoma pane) dhayamita yepore yepasi diatomaceous, zvimedu zvakasimba "zvinenge zvichiongororwa" kunze kwekumisikidzwa, zvichiita basa mukusefa pamusoro.
2. Zvakadzika mhedzisiro
Iyo yakadzika mhedzisiro ndeyekuchengeta mhedzisiro yekudzika filtration. Mukutsvaira kwakadzika, nzira yekuparadzanisa inongoitika mukati mepakati. Zvimwe zvezvimedu zvidiki zvisina kuchena zvinopfuura nepamusoro pekeke resefa zvinovhariswa nemhepo inomonereka microporous chiteshi mukati mediatomaceous pasi uye maburi madiki mukati mesefa keke. Zvimedu izvi zvinowanzova zvidiki pane ma micropores ari mu diatomaceous pasi. Kana zvimedu zvinodhumana nemadziro echiteshi, zvinokwanisika kubvisa kubva pakuyerera kwemvura. Zvisinei, kana vachikwanisa kuita izvi zvinoenderana nekuenzanisa pakati pesimba re inertia uye kushorwa kwezvikamu. Uku kubata uye kuongorora chiitiko kwakafanana muchimiro uye ndezvemuchina chiito. Iko kugona kusefa kunze kwakasimba zvimedu zvinongoenderana nehukuru hwehukama uye chimiro chezvimedu zvakasimba uye pores.
3. Adsorption effect
Iyo adsorption mhedzisiro yakasiyana zvachose kubva kune mbiri yekusefa nzira dzataurwa pamusoro, uye mhedzisiro iyi inogona kunyatsoonekwa seye electrokinetic kukwezva, iyo inonyanya kuenderana nepamusoro pezvimedu zvimedu zvakasimba uye diatomaceous pasi pacharo. Kana zvimedu zvine maburi madiki emukati zvichidhumhana nepamusoro pevhu rinoputika diatomaceous pasi, zvinokwezvwa nemhosva dzakapesana kana kuumba macheni masumbu kuburikidza nekukwezvana pakati pezvimedu uye kunamatira kune diatomaceous pasi, zvese zviri zveadsorption. Iyo adsorption mhedzisiro yakanyanya kuomarara kupfuura maviri ekutanga, uye inowanzo davirwa kuti chikonzero chinoita kuti zvimedu zvimedu zvine madhayamita madiki epore zvipindirwe zvinonyanya kukonzerwa ne:
(1) Intermolecular forces (inozivikanwawo sevan der Waals attraction), kusanganisira zvachose dipole kupindirana, induced dipole kudyidzana, uye pakarepo dipole kudyidzana;
(2) Kuvapo kweZeta zvinogona;
(3) Ion kuchinjana maitiro.
