Nyob rau hauv xyoo tsis ntev los, kev muag khoom ntau thiab ntau high-quality xim tshaj lub xeb, los ntawm kev uas leej twg yuav tsis tau tsuas yog txig hloov lub qub kho vajtse, tab sis kuj cawm tau ib tug ntau ntawm cov sij hawm nyob rau hauv ua li ntawd. Ntau ntev los no, nyob rau hauv thiaj li yuav hloov, piv txwv li, tus nqaj hlau los yog tuav nyob rau hauv lub qhov rais, lawv yuav tsum tau muab pre-kho nrog ntwav txhuam ntoo los yog ib tug sib tsoo tshuab (kom tshem tawm cov qub txheej), luam nto thiab xwb ces thov tshiab enamel. Niaj hnub nimno cov xim tsev, xeb yuav siv tsis tau pre-kev kho mob, uas yog heev txaus rau lawv yuav txaus siab.
Txawm tias pheej advertising, ntau cov kev pab tseem xav tias ib tug tsis muaj kev cog qoob loo nyob rau hauv no hom ntawm cov xim muaj hlau cov khoom. Seb puas yuav tso siab rau cov manufacturers ntawm cov coatings los yog tsis? Nyob rau hauv qhov tseeb, buyers yuav tsum paub hais tias yuav luag tag nrho cov ferrous co sai sai xeb nyob rau hauv lub xub ntiag ntawm dej thiab oxygen. Nws tsis yog qhov txhia chaw thiab tsis yeej ib txwm muaj peev xwm tsis tu ncua siv rau cov lug, xws txoj kev tiv thaiv raws li tu xeb, priming, daim ntawv thov ntawm cov xim tsev thiab varnishes. Nyob rau hauv cov ntaub ntawv no, tsuas tau txoj kev, thiab feem ntau mus siv cuag nto kev kho mob yog ib tug txheej ntawm xim tshaj lub xeb. Ib txhia ntawm lawv yog los ntawm dej los muaj phosphoric acid. Feem ntau xim rau hlau thiab xeb ob-muaj additive raws li resins ntawm epoxy los yog polyurethane thiab xeb inhibitors.
Dej-mov compositions yog cov feem ntau environmentally tus phooj ywg thiab pheej yig, tab sis lawv siv raws li ib tug "finishing" coatings tsuas tau nyob rau hauv tus neeg mob qhov twg cov hlau lug mus rau qhov chaw tsis hais tias, siab decorativeness, thiab lawv yog siv nyob rau hauv tej yam kev mob ntawm kuj tsis tshua muaj Aggressiveness ntawm qhov chaw. Tej compositions yog zoo tshaj plaws ua ntawv thov mus rau lub luam nto. Qhov zoo tshaj plaws cov xim tsev, xeb daim ntawv coatings uas maximally cais tawm lub hlau nto tiv thaiv corrosive tshuaj, oxygen thiab dej. Lawv hloov cov tshuaj muaj pes tsawg leeg ntawm lub heev xeb, uas ho slows cia cov tug dab ntawm corrosion. Tsis txhob hnov qab hais tias, tsis muaj teeb meem zoo li cas cov coatings, xoob xeb tseem yuav tsum xub raug tshem tawm ntawm cov hlau nto, vim hais tias tsis muaj xim tsis tau "khi" nws rau ib ntev lub sij hawm nyob rau nws los tuav.
Muaj ntau ntau hom ntawm anti-xeb coatings. Ib qho ntawm feem nrov cov ntawm no lub hom yog cov xim ntawm xeb "Hamerayt" (Hammerite). Nws yog ib qho yooj yim mus thov vim hais tias nws muaj ob peb lub zog ib txhij: converts xeb txheej yog ib phau pib qhia thiab topcoat. Nws yog noteworthy uas Hammerite xim nyob rau hauv ntau yam khaubncaws sab nraud povtseg yuav tau mus thov nyob rau hauv ib hnub. Qhov no xim txheej muab ib tug hniav hlau lug tsos thiab tiv thaiv zoo. Qhov no xim tsis npaj rau industrial siv. Qhov zoo tshaj plaws cov nyhuv yog tiav thaum koj ua ntawv thov ib tug txheej thickness ntawm tsis tsawg tshaj li 100 microns. Xim tsev "Hamerayt" muaj peev xwm ntawm repelling dej, vim hais tias lawv muaj silicones. Qhov no txheej yog ua lub hauv paus ntawm ib tug complex ntawm resins tsim los xauv xeb. Nws muaj hloov alkyds muab zoo adhesion rau hlau chaw. Fast evaporating kuab tshuaj tam sim no nyob rau hauv nyob tus yeees ntawm cov xim nyob rau xeb "Hamerayt" ua rau kom nws cov ceev ceev kom qhuav. Khob microparticles kom cov waterproof barrier. Qhov no xim yog thov tsuas yog nyob rau qhov chaw tsis flake tawm, uas tau raug pleev xim rau yam tsawg rau lub hlis ua ntej lawm. Painting "Hammerayt" yog tsis sib xws nrog compositions raws li nyob rau hauv bitumen. Thaum ua ntawv thov rau cov uas tsis-ferrous co yuav tsum tau ua ntej priming.
