1. I-county inokumelana nokuguga okubalaseleyo, kwaye ukuchasana kwevumba kumalunga ne-10% ephezulu kunerabha yendalo kunye nerubha engaxutywanga.Iyakwazi ukuvezwa kukukhanya kwelanga kunye nomoya ixesha elide, akukho lula ukuguga, ukumelana nobushushu obuphantsi - 40C, ukumelana nobushushu obuphezulu 120 ℃.
2. Umoya ogqwesileyo kunye nokuqina kwamanzi, ukunyanzeliswa komoya malunga ne-1 / 20 yerubha yendalo, i-asidi kunye nokumelana ne-alkali kunye nokugquma.Ukusebenza okugqwesileyo, yimveliso yeempawu ezisetyenziswa kubunjineli obungenamanzi obungaphantsi komhlaba;
3. Yimveliso ehambelana nokusingqongileyo, engangcolisi kwaye ayinakutsha, ngokukodwa ifanelekile kwiitayili zetsimbi ezinemibala, iintsimbi ezinemibala, i-waterproof kunye nezinye izinyithi.Uphahla olungangeni manzi, ukugcinwa kophahla oludala, umaleko wokuqala wokungena manzi akufuneki ususwe;
4. Ukwakhiwa okubandayo, ukusebenza okulula, ukugcinwa kwenkonzo yokuzimela, ukwakhiwa kwamanzi ebusika kwi-10 ° C kusenokwenziwa;
5. Ngenye yezona zinto zingabizi kakhulu ezingenamanzi ngoku, kwaye ubomi benkonzo yokungena manzi yophahla olubonakalayo lungaphezu kweminyaka eyi-10.
