Cov khoom siv roj hmab yog cov khoom siv tseem ceeb heev vim lawv cov elasticity zoo heev, hnav tsis kam, corrosion kuj, thiab lwm yam khoom. Lawv tau siv dav hauv kev lag luam xws li tsheb, log tsheb, khau, hnab looj tes, xov hlau thiab cables, kev tsim kho, thiab khoom siv kho mob. Zinc oxide hmoov yog ib qho tseem ceeb ntxiv rau hauv cov txheej txheem roj hmab.
Muaj qib zinc oxide hmoov yog hais txog insoluble zinc oxide nrog ib qho me me ntawm 2 microns thiab 10 microns, feem ntau yog cov hmoov dawb los yog daj me ntsis, uas tuaj yeem ruaj ntseg khaws cia thiab siv hauv huab cua. Hauv kev ua cov khoom siv roj hmab, zinc oxide hmoov tuaj yeem ua tus txhawb nqa thiab ua kom muaj zog, ua kom cov txheej txheem vulcanization ntawm cov roj hmab ua thiab txhim kho lub cev thiab ua haujlwm ntawm cov khoom siv roj hmab.
Daim ntawv thov zinc oxide hmoov hauv cov khoom siv roj hmab yog qhov dav heev, thiab tam sim no kwv yees li 60% ntawm cov khoom siv roj hmab hauv khw muaj zinc oxide hmoov. Piv txwv li, hauv kev tsim cov log tsheb, zinc oxide hmoov tuaj yeem txhim kho qhov tseem ceeb ntawm cov log tsheb thiab txuas ntxiv lawv lub neej kev pab cuam; Hauv kev lag luam kws tshuaj, zinc oxide hmoov feem ntau yog siv los tsim cov hnab looj tes kho mob thiab lwm yam khoom siv kho mob, nrog rau kev tiv thaiv hnub ci, ntxuav hniav dawb, tshuaj tua kab mob, thiab tshuaj tiv thaiv kab mob.
Hauv cov ntsiab lus, kev lag luam qib zinc oxide hmoov, ua ib qho tseem ceeb ntxiv, muab kev txhawb nqa tseem ceeb thiab kev lees paub rau kev tsim thiab siv cov khoom siv roj hmab. Peb yuav tsum nquag txhawb nws txoj kev loj hlob thiab kev siv, thiab txhawb kev nce qib thiab kev loj hlob ntawm cov khoom lag luam roj hmab.
