1. Iyo County ine kuchembera kwakatanhamara, uye kunhuhwirira kunenge kwakakwira 10% kupfuura iyo yerabha yechisikigo uye unsaturated rubber.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, kupindira kwemhepo kunenge 1/20 yerabha yechisikigo, asidhi uye alkali kuramba uye kuvharirwa.Kuita kwakanakisa, chigadzirwa chehunhu chinoshandiswa muinjiniya yepasi pevhu isina mvura;
3. Icho chigadzirwa chezvakatipoteredza, chisingasvibisi uye chisingabatiki, chakanyatsokodzera matarenda 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;
