(1) Magasket eEPDM haafanire kusangana nezvinonyungudutsa zvinonhuhwirira kweinenge hafu yeawa.

(2) Rutivi rwekumashure rweplate harugone kubata pasi zvakananga pakuchenesa.

(3) Mushure mekuchenesa nemvura, nyatsoongorora maplate nemagasket uye hapana zvasara zvakaita sezvidimbu zvakasimba nemafiber zvinobvumirwa pamusoro peplate. Gasket yakabviswa uye yakakuvara inofanira kunamirwa kana kutsiviwa.

(4) Paunenge uchichenesa nekushandisa michina, bhurashi resimbi haritenderwi kushandiswa kudzivirira kukwenya ndiro negasket.

(5) Pakuchenesa nepfuti yemvura ine simba guru, ndiro yakasimba kana ndiro yakasimbiswa inofanira kushandiswa kutsigira ndiro kumashure (ndiro iyi inofanira kubatwa zvizere nendiro yekuchinjana kupisa) kudzivirira kushanduka, daro riri pakati pemuromo nendiro yekuchinjana haifanirwe kunge riri pasi pe200 mm, kumanikidzwa kwepamusoro kwejekiseni hakufanirwe kupfuura 8Mpa; Panguva iyi, kuunganidzwa kwemvura kunofanira kutariswa kana uchishandisa pfuti yemvura ine simba guru kudzivirira kusvibiswa panzvimbo yacho nezvimwe zvishandiso.

2  Kuchenesa makemikari

Pakusvibisa kwakajairika, zvichienderana nehunhu hwayo, chinhu chinoshandiswa pakuchenesa chinogona kushandiswa pakuchenesa zvinhu zvakaita sealkali ine huwandu hwehuremu hushoma kana hwakaenzana ne4% kana chinhu chinoshandiswa pakuchenesa zvinhu zvine acid hushoma kana hwakaenzana ne4%.

(1) Kuchenesa tembiricha: 40 ~ 60 ℃.

（2）Kupukuta musana pasina kupatsanura michina.

a) Batanidza pombi panzvimbo inopinzwa neinoburitswa nemagetsi pachine nguva;

b) Batanidza michina ne "mota yekuchenesa michina";

c) Pomba mushonga wekuchenesa mumidziyo nenzira yakatarisana nekufamba kwechigadzirwa;

d) Tenderedza mvura yekuchenesa kwemaminitsi gumi kusvika gumi nemashanu padanho rekuyerera kwemvura riri pakati pe0.1 ~ 0.15m/s;

e) Pakupedzisira dzokorora mvura yakachena kwemaminitsi mashanu kusvika gumi. Huwandu hwechloride mumvura yakachena hunofanira kunge huri pasi pe25ppm.

Ndapota Cherechedzai:

(1) Kana nzira iyi yekuchenesa ikashandiswa, chinongedzo chekuchenesa chinofanira kusara chisati chabatanidzwa kuti mvura yekuchenesa ibude zvakanaka.

(2) Mvura yakachena inofanira kushandiswa pakusuka chinoshandiswa pakupisa kana chikabviswa mvura yekumashure.

(3) Mushonga wekuchenesa wakakosha unofanirwa kushandiswa pakuchenesa tsvina chaiyo zvichienderana nemamiriro ezvinhu chaiwo.

(4) Nzira dzekuchenesa nedzemakemikari dzinogona kushandiswa pamwe chete.

(5) Pasinei nekuti ndeipi nzira inoshandiswa, hydrochloric acid haibvumirwi kuchenesa ndiro yesimbi isina ngura. Mvura ine chlorion inodarika 25 ppm haifanirwe kushandiswa kugadzira mvura yekuchenesa kana ndiro yesimbi isina ngura.
