Tshooj nyob rau lub ncauj lus: Polypropylene Ropes: nta thiab cov nyom ntawm daim ntawv thov
Lub puag ncig ntawm kev kho kom zoo nkauj tas yog tseem yog qhov kev txhawb nqa kaum tsev, uas yog siv los plaster cov ces kaum.
Qhov tseem ceeb ntawm kev ua haujlwm tiav, nws tseem muaj me ntsis. Lub qhov rais twb tau sib txawv kiag li.
Tom qab txoj kev daws teeb meem qhuav tag, nws yog ib qho tsim nyog rau hom peb tsim nrog cov txheej txheem tshwj xeeb hauv ntej av.
Thov siv cov txheej kawg ntawm xov - cov plaster zoo nkauj.
Koj tuaj yeem thov nws nrog lub cev ntaj ntsug lossis tshwj xeeb ib nrab-sash. Cov txheej txheem yooj yim heev. Cov plaster suav nrog cov tub rog abrasive (granules) ntawm kwv yees li ntawm tib qho loj me, yog li txheej yuav tig mus ua ib qho tuab uas tsis muaj kev siv zog tshwj xeeb.
Cov tsiaj no yuav muaj lub qhov rai thaum ua tiav kev ua haujlwm.
