Qhov tseeb, kev xeem mob ntawm MCM cov ntawv tuaj yeem nqa tawm rau lub sijhawm ntev. Nws yog feem ntau ntseeg hais tias lub sij hawm ntawm cov kev sim ua kom sai sai yog zoo correlated nrog lub sijhawm ua si sab nraum zoov. Cov txheej txheem kev sim siab ceev nrawm rau cov txheej txheej qub yog 250H, uas tuaj yeem siv sab nraud rau 3-5 xyoos. Tom qab ntawd MCM cov ntawv txheeb 3500H, raws li tus qauv no, yog sib npaug rau 50 xyoo sab nraum zoov.

Npaum li cas yog anti - fouling cov cuab yeej ntawm MCM cov ntawv txheeb?
Qhov yooj yim sib xyaw ntawm MCM cov ntawv yog hloov kho cov av hloov pauv los ntawm av dog dig thiab hmoov av. Yog li, cov khoom siv lub cev ntawm MCM cov ntawv yog ruaj khov thiab nruab nrab, tsis muaj hluav taws xob zoo li qub, thiab lawv tsis nqus hmoov av thiab stains.
