Sive molekụla

Sive molekụla bụ adsorbent siri ike nke nwere ike ikewapụta ụmụ irighiri ihe dị iche iche.Ọ bụ SiO2, Al203 dị ka kristal aluminom silicate na isi akụrụngwa.Enwere ọtụtụ oghere nke otu nha na kristal ya, ma enwere ọtụtụ oghere nke otu dayameta n'etiti ha.Ọ nwere ike ịgbanye ụmụ irighiri ihe dị ntakịrị karịa dayameta pore n'ime oghere ahụ, ma wepụ ụmụ irighiri ihe karịrị oghere n'èzí, na-arụ ọrụ sieve.

Molecular sieve nwere ikike nnabata mmiri siri ike, yana ihe fọrọ nke nta ka ọ bụrụ ihe mgbaze niile enwere ike iji kpoo ya, yabụ a na-eji ya na ụlọ nyocha na ụlọ ọrụ.Molecular sieve adsorption usoro bụ usoro akpịrị ịkpọ nkụ na obere ike oriri na arụmọrụ dị elu, usoro ahụ dị mfe, dabara adaba maka mmiri mmiri mmiri na gas miri emi, ojiji nke nha nke molecular sieve aperture nhọrọ adsorption nke mmiri, nke mere na nweta nkewa.

Nkwụsi ike nke okpomọkụ nke sieve molecular dị mma, nke nwere ike iguzogide obere okpomọkụ dị elu nke 600C ~ 700C, na mmeghari okpomọkụ ekwesịghị ịfe 600C, ma ọ bụghị na-emetụta ọrụ nke sieve molecular, a pụkwara ịchụpụ ya (enweghị mmeghari ọkụ).Achịcha molekụla ahụ adịghị edozi na mmiri, ma na-agbaze na acid siri ike na alkali, ya mere enwere ike iji ya mee ihe na pH5 ~ 11.Sive molecular dị mfe ịmịnye mmiri, kwesịrị ka a mechie nchekwa, ojiji kwesịrị ịlele ma ọdịnaya mmiri karịrị ọkọlọtọ, nchekwa maka ogologo oge absorption nke mmiri, kwesịrị iji ya mee ihe mgbe ejiri ya mee ihe, arụmọrụ ya agbanweghị.Molecular sieve nwere njiri mara nke ngwa ngwa adsorption ọsọ, ọtụtụ oge mmeghari, nnukwu ngwepịa ma na-eyi nguzogide, mmetọ mmetọ siri ike, arụmọrụ dị elu, ogologo ndụ ọrụ, wdg, nke bụ ọkacha mmasị desiccant maka gas na mmiri mmiri oge ihicha miri emi.
