Flooring thiab cov vaj tse Fesers:CurfuryL cawv yog siv los ua ib qho sib xyaw ua ke hauv qee hom flooring thiab cov pob zeb ua vaj tse. Nws pab nyob rau hauv kev tsim ntawm ib zaj yeeb yaj kiab ruaj khov thiab tiv thaiv uas txhim kho cov saum npoo tsis kam tshuaj, puas, thiab noo noo. FurfutyL cawv raws li kev sib tsoo feem ntau siv rau kev lag luam thiab kev lag luam pem teb.
Agricultural khoom:CurfuryL cawv yog qee zaum siv los ua kev tswj hwm kev loj hlob thiab txuag kev lag luam hauv kev ua liaj ua teb. Nws tuaj yeem siv rau cov nroj tsuag thiab cov qoob loo kom txhim kho lawv txoj kev loj hlob thiab tawm los. Cov khoom siv dej cawv tsis muaj cawv kuj tseem siv tau los ua cov qoob loo qoob loo kom tiv thaiv cov kab kev loj hlob ntawm qee cov kab thiab fungi.
Cov kuab tshuaj:FurfuryL Cawv muaj cov khoom muaj kuab thiab tuaj yeem siv los ua cov kuab tshuaj hauv ntau yam kev siv. Nws yog tshwj xeeb muaj txiaj ntsig nyob rau hauv dissolving Resins, waxes, roj, thiab lwm cov organic teb. CurfuryL cawv tuaj yeem siv los ua cov kuab tshuaj hauv kev tsim khoom ntawm cov txheej txheem, lacquers, thiab xim pleev xim rau.
Tsw thiab cov ntxhiab:CurfuryL cawv yog ib txwm nyob rau hauv ntau cov txiv hmab txiv ntoo, zaub, thiab nplej, ua rau lawv qab thiab tsw qab. Nws yog siv los ua cov neeg sawv cev saj hauv cov khoom noj thiab dej haus cov khoom lag luam, muab cov khoom qab zib, caramel zoo li qab. Dej cawv kuj tau siv hauv kev lag luam ntxhiab tsw ntxiv kom ntxiv qhov sov sov, woody ntxhiab tsw rau cov naj hoom thiab colognes.
Nws yog ib qho tseem ceeb kom nco ntsoov tias cov ntawv thov tshwj xeeb thiab kev siv ntawm FurfuryL cawv yuav sib txawv nyob ntawm kev lag luam thiab nws cov kev xav tau. Tsis tas li ntawd, kev ceev faj kev nyab xeeb yuav tsum tau ua raws thaum tuav dej caw thiab siv FurfuryL dej vim nws cov nplaim taws.
