Zvirongo zvakavharwa zvisina kushandiswa kwenguva refu kazhinji hazvigone kuvhurwa.Chikonzero chikuru chekutadza kuvhura iyochirongo chepurasitikindeyekuti mhepo yekunze yemhepo yakakwirira kudarika yemukati yemhepo.Kana iwe uchida kuvhura chivharo, iwe unofanirwa kuyera kudzvanywa kwemhepo mukati nekunze kwetangi rekuchengetedza.

 
1. Shandisa mapanga anopinza nezvimwe zvakadaro, zvinyoronyoro vhura pamucheto wevhavha yebhodhoro kuti uchengetedze mukati uye kunze kwemhepo yemhepo yakagadzikana, uye wozovhura;2. Shandisa simbi isina tsvina, zvipunu zvendarira, makiyi, kuputira machira emapepa kuti uwedzere kukweshana, uye ipapo Pry chivharo chebhodhoro pamucheto wemuromo webhodhoro kuti mhepo ipinde mugaba, wozoivhura;3. Shandisa banga rinopinza kana zvimwewo kuti uboora buri muchivharo kuti usunungure mhepo, uye simba remhepo riri mukati nokunze kwebhodhoro rinogona kuvhurwa.4. Shandisa pamba Iro rinopisa bvudzi rinopisa rinoramba richipisa chivharo chebhodhoro kubva kure kusvika pedyo, uye pakupedzisira unogona kuzarura chigadziko chemhepo;5. Pindura gaba remhepo kusvika kune 45-degree angle, wobva wabata gaba remhepo, bata pasi pegaba, uye chivharo chichazarura.Nheyo ndeyekupa chirongo chekukurudzira, chirongo chakavharwa chinomiswa, uye chikamu chechivharo chicharamba chichifamba nekuda kweinertia, uye kutungamira ndiyo kutungamira kubva pachivharo, saka ichave yakasununguka.Kune rumwe rutivi, nokuti chirongo chakavharwa kwenguva yakareba, chivharo chechirongo chakavharwa chinonetsa kubvisa nekuda kwesimba re intermolecular, uye kugogodza chivharo kunewo kukanganisa kwekuputsa simba re intermolecular;6. Sora chirongo chakavharwa muhari, uye wozoshandisa 80 Chichipisa nemvura inopisa kwehafu yeminiti (ona kuti nguva yekupisa haifaniri kunge yakareba), kana iwe unogona kudurura chivharo nemvura inopisa kwemaminitsi mashomanana, wozodhonza chivharo nesimba kuti uvhure.
