1. Dunhu rine kurwisa kuchembera kwakatanhamara, uye kunhuhwirira kunoda kukwira ne10% kupfuura kwerabha rechisikigo nerabha isina unsaturated.Inogona kuratidzirwa kune chiedza chezuva nemhepo kwenguva yakareba, isiri nyore kuchembera, yakaderera tembiricha kuramba - 40C, yakakwirira tembiricha kuramba 120 ℃.
2. Yakanakisa mhepo uye kuomeswa kwemvura, kufema kwemhepo kunosvika 1/20 yerabha yechisikigo, asidhi uye alkali kuramba uye kuvhara.Kuita kwakanakisa, chigadzirwa chehunhu chinoshandiswa muinjiniya yepasi pevhu isina mvura;
3. Icho chigadzirwa chezvakatipoteredza, chisingasvibisi uye chisingabatiki, chakanyatsokodzera matombo esimbi ane mavara, mashizha ane mavara, asina mvura uye mamwe masimbi.Denga risina mvura, rekare rekugadzirisa denga, yepakutanga isina mvura layer haidi kubviswa;
4. Kuvaka kutonhora, kushanda kuri nyore, kuzviitira basa rekuchengetedza, kuvakwa kwemvura munguva yechando - 10 ° C inogona kuramba ichiitwa;
5. Icho chimwe chezvinhu zvinodhura-zvinobudirira zvisingasviki mvura panguva ino, uye hupenyu hwebasa remvura yedenga rakafumurwa makore anopfuura gumi.
