Zviyo zvakachengetwa kana kukohwa, zvingave zvakachengetwa mudura rezviyo kana kuti kumusha kwevarimi, kana zvikachengetwa zvisina kufanira, zvichakanganiswa netwumbuyu twakachengetwa. Vamwe varimi varasikirwa zvikuru nekuda kwekutapukirwa kwetwumbuyu twakachengetwa, twupukanyi twunosvika mazana matatu pakirogiramu yegorosi uye kuderera kwehuremu nechikamu che10% kana kudarika.

The biology yezvipembenene zvekuchengetedza kugara uchikambaira mukati memurwi wezviyo. Pane nzira yekudzora zvipembenene zvekudya zvakachengetwa pasina kushandisa mishonga yekuuraya zvipembenene yemakemikari ine nharaunda uye hutano hwevanhu? Hongu, idiatomite, mushonga wezvipembenene chaiwo unoshandiswa kuchengeta zvipembenene zvezviyo. Diatomite inzvimbo ye geological dhipoziti yakaumbwa kubva kufossilized skeletons ezvipenyu zvakawanda zveMarine nemvura yakachena zvine sero rimwe chete, kunyanya diatoms uye algae. Aya madhipatimendi ane makore angangoita mamirioni maviri apfuura. Diatomite poda yemhando yakanaka inogona kuwanikwa nekuchera, kupwanya uye kugaya. Semushonga unouraya zvipembenene, diatomite poda inokwanisa kunwa zvakanaka uye ine tarisiro yekushandiswa kwakafara mukudzora tumbuyu twakachengetwa. Diatomite yakapfuma muzviwanikwa, isiri-chepfu, haina hwema uye iri nyore kushandisa. Nokudaro, zvinokurudzirwa kuti zvishandiswe kumaruwa kugadzira nzira itsva yekurwisa zvipfukuto zvezviyo zvakachengetwa kumaruwa. Pamusoro pekugona kunyura kwakanaka, saizi yechidimbu, kufanana, chimiro, pH kukosha, fomu yedosi uye kuchena kwe diatomite zvinhu zvakakosha zvinokanganisa mhedzisiro yayo yezvipembenene. Diatomite ine yakanaka insecticidal mhedzisiro inofanirwa kuve yakachena amorphous silicon ine chidimbu dhayamita <. 10μm(micron),pH <8.5, inongova nevhu shoma uye isingasviki 1% crystalline silicon.

Zvinhu zvakasiyana-siyana zvinokanganisa diatomite poda yekudzora zvipembenene zvakachengetwa zvakadzidzwa muUnited States: fomu yepimo, dhigirii, muedzo wezvipembenene, nzira yekubatana pakati pezvipembenene uye diatomite, nguva yekubatana, zviyo zvakasiyana-siyana, zviyo zvezviyo (zviyo zvose, zviyo zvakaputsika, hupfu), tembiricha uye mvura yezviyo, nezvimwewo.

Sei diatomite ichigona kuuraya zvipembenene zvezviyo zvakachengetwa?

Izvi zvinodaro nekuti diatomite poda ine simba rakasimba rekutora esters. Muviri wezviyo - kuchengetedza zvipembenene zvine nzvimbo yakaoma uye yakawanda bristles. Diatomite hupfu hunokwesha pamusoro pemuviri wehupfu hwezviyo zvakachengetwa pahunokambaira nepakati pezviyo zvakabikwa. Rutivi rwokunze rwemadziro emuviri wetumbuyu hunonzi epidermis. Mu epidermis pane chidimbu chitete chewakisi, uye kunze kwewakisi pane chidimbu chitete chine esters. Kunyange zvazvo wakisi newakisi inodzivirira yakaonda zvikuru, inoita basa rinokosha zvikuru pakuchengeta mvura mukati memutumbi wezvipembenene, unova “mudziviriro wemvura” wetumbuyu. Mune mamwe mazwi, "mvura inodzivirira" inogona kuchengetedza mvura mukati memuviri wezvipembenene kubva pakubuda uye kuita kuti irarame. Diatomite poda inogona kutora zvine simba esters uye wax, ichiparadza "mvura inodzivirira" yezvipembenene, zvichiita kuti varasikirwe nemvura, varemerwe uremu uye pakupedzisira vafe.
