Roj hmab lined butetrfly valve

Tag nrho cov roj hmab lined npauj npaim li qub ntawm kev ntseeg siab, tsim kom muaj zog raws li qhov phem tshaj plaws nyob ib puag ncig.

Ebonite hauv ob sab phlu: muaj tshuaj zoo stability, zoo heev tshuaj corrosion kuj thiab organic hnyav kuj, tsis tshua muaj dej nqus, siab tensile zog thiab zoo heev hluav taws xob rwb thaiv tsev etc.features.

Lub ebonite hauv ob sab phlu tsim cov txheej txheem txuas ntxiv ntawm cov substrate ntxiv cov qauv tsim tshwj xeeb thiab cov txheej txheem ntawm kev sib koom ua ke kom cais cov ferrous substrate los ntawm cov kev pabcuam nruab nrab, yog li ua kom cov khoom siv sijhawm ntev.Rau cov kua dej corrosive, nws yuav yog ib qho kev daws teeb meem ntau dua.

Cov cheeb tsam yuav tsum tau tiv thaiv los ntawm ebonite hauv ob sab phlu yuav tsum tau xuab zeb blasted kom pom cov hlau dawb thiab ncav cuag kev huv si Sa 2.5 rau ISO 8501 thiab roughness nruab nrab G rau ISO 8503.

Nyob rau hauv ib puag ncig nrog cov av noo tsis tshaj 60% thiab qhov kub ntawm 15-40 ℃, siv cov cuab yeej hauv ob sab phlu, xws li lub siab rau cov menyuam thiab scraper kom ua tiav cov ntaub ntawv roj hmab thiab cov substrate raws li cov txheej txheem nruj thiab cov kev cai.

Lub ebonite hauv ob sab phlu vulcanization txheej txheem nrog cua kub los yog chav nyob rau hauv lub vulcanization kettle.

Cov txheej txheem tom ntej tuaj yeem pib tsuas yog tom qab dhau ntau yam kev sim thiab tshuaj xyuas (kev tshuaj xyuas qhov muag, hluav taws xob kuaj pom rau hnub so / pinholes / tawg, adhesion test thiab hardness test etc.)

Lub hardness range yuav tsum ua tiav Ntug D 75 ± 5

Kev tiv thaiv corrosion sab nraud: cov txheej txheem pleev xim hauv qab no yog muab rau kom haum rau daim ntawv thov C5 corrosivity qeb raws li EN ISO 12944-2,

Epoxy zinc-nplua nuj primer - 60μm, Epoxy micaceous hlau / nruab nrab xim - 120μm, Acrylic polyurethane tiav xim - 60μm, Tag nrho qhuav sau thickness (DFT) 240μm

Epoxy iav flake primer- 80μm, Epoxy iav flake xim ob txheej - 160μm, Tag nrho qhuav sau thickness (DFT) 240μm

Tag nrho cov fastenings sab hauv thiab sab nraud xws li txiv ntseej, bolts, screws thiab fittings yuav tsum yog stainless hlau qib 316L los yog duplex stainless hlau.

Tag nrho cov roj hmab lined npauj npaim li qub tsim nyog yuav tsum tau kho nyob rau hauv txoj hauj lwm ntsug los yog kab rov tav txoj hauj lwm.

Lub qhov muag lifting / lifting nuv tsau nyob rau hauv txoj hauj lwm tsim nyog kom lub valve tuaj yeem nqa tau nyob rau hauv txoj hauj lwm ntsug lossis kab rov tav.
