Chii chinonyanya kukosha nezvehombodo yemafuta? Chii icho? Vaya vasikana vanotenga zvinonhuhwirira zvebhodhoro, vanoziva chinangwa chikuru chezvimedu zvisina chinhu. Zvigadzirwa zvegirazi zvakadaro zvinoshandiswa pakutsanura zvinonhuwira, uye kana zvichienderana nemitemo yekushanda kwavo, dzinogona kushanda kwenguva yakareba.
Chii chakanaka mabhodhoro egirazi ezvinonhuwira?
Girazi chinhu chinokubvumira kufungidzira nekugadzira mifananidzo yezvipfeko zvekunakisa. Mukuwedzera, inogona kuchengetedza maitiro emvura iyo inodururwa mairi kwenguva yakareba.
Girazi chinhu chakasagadzikana chemakemikari, kuitira kuti zvikamu zvaro zvirege kuita nemafuta ezvinonhuwira. Pakupedzisira, kunyange iwe ukachengetedza zvinonhuwira muhomba yegirazi kwemakore nemakumi emakore, hazvizokanganisa kunhuwirira kwezvinonhuwira munzira ipi zvayo.
Kana zvinonhuwira zvigadzirwa zvekipaque, izvi zvichavadzivirira kubva pakusvibiswa kwezuva, izvo zvingashandura mararamiro uye kunhuhwirira, sezvavanotanga mutsara wemakemikari kuitika mumvura. Iyo yakajeka bhodhoro, iyo midzimu yakareba mairi ichachengetedza kunhuhwira kwayo kwepakutanga.
Mafuta ezvinonhuwira zvakasiyana-siyana
Zvichienderana nehutano hwavo, pamwe chete nemhando yemutsipa, mabhodhoro aya emhando dzakawanda:
- bhodhoro rine mitsipa kune chekuya;
- bhodhoro rine mutsi pasi pekumisa;
- bhodhoro rine vheti yeaerosol;
- bhodhoro iri pasi pevhavha yepiritsi.
Zvichienderana netsika yekurapa, mabhodhoro acho anogona kuputirwa nehupamhi hwepamusoro, pamwe nekubatanidzwa kwezvimwe mishonga (etching, kudhinda, metallization, galvanizing) kana kunyange pasina kurapwa.
Mukuwedzera, mabhodhoro asina mafuta asina chinhu haasi nguva dzose girazi. Kunewo mahwendefa akaita mapurasitiki. Zvechokwadi, mavari kuchengeta mafuta akawanda haafariri, nokuti haasi sepamusoro-soro segirazi.
Mipata yemweya inodhura yemafuta yakasiyana nekugadziridzwa kwayo kwakakosha. Aya mabhodhoro akanaka emafuta anowanzoitwa muruvara rweArabic uye akaisvonaka pakuteya nekuchengetedza mafuta nemafuta. Iyo yakavakwa mumatanda kuitira kushandiswa kwezvinonhuwira, uye midziyo inowedzera nechitsiko chesimbi chekuyera nekudzivirira kubva pakuwa.
Kune mvura inonhuhwirira, mabhodhoro ari kujekesa, nyore. Kazhinji kazhinji ivo vakagadzirirwa nevanosvina. Mabhodhoro akadaro ane simba guru - 30-100 ml. Nekugadzirisa kwemashoko emidziyo yakadaro, vanogadziri vanowanzopa ma-cardboard mabhokisi kuitira kuti maonero enyu aoneke akakodzera.
