Txheem rau Fiberglass Reinforced Polypropylene FRPP Yeeb Nkab:
Ua HG 20539-92.
Kev tsim cov iav fiber ntau hloov cov ntaub ntawv polypropylene kho nrog cov neeg ua haujlwm sib txuas rau kev thauj mus los ntawm cov dej thiab cov kua dej corrosive rau lub hom phiaj dav dav.
Kev tu cev ntawm cov kav dej haus tau raws li qhov yuav tsum tau ua ntawm GB / T17219.
Fiberglass reinforced polypropylene FRPP kav dej muaj qhov zoo heev thiab kev pabcuam lub neej. Raws li qhov ntsuas kub thiab qhov siab, FRPP kav dej tuaj yeem siv tau zoo rau 50 xyoo.
Kev tiv thaiv corrosion zoo heev - muaj peev xwm tiv taus corrosion ntawm cov tshuaj feem ntau thiab tiv taus cov kua qaub thiab alkali siab nrog pH qhov tseem ceeb xws li 1-14 ntau yam.
Kev hnav zoo heev - Thaum thauj cov ntxhia xuab zeb slurry, hnav tsis kam ntawm FRPP kav dej yog ntau tshaj 4 npaug ntawm cov kav hlau.
Siab tawv - vim qhov sib ntxiv ntawm cov khoom siv fiberglass, FRPP cov kav dej tsis yooj yim deformed.
Rwb thaiv tsev tiv thaiv tshav kub thiab txuag hluav taws xob - FRPP cov kav dej muaj qhov ua haujlwm kub ntawm ib puag ncig 95 degrees Celsius. Lub thermal conductivity ntawm cov khoom no tsuas yog 1/200 ntawm cov yeeb nkab steel, yog li nws muaj kev ua haujlwm zoo rwb thaiv tsev.
Txhim khu kev sib txuas kev ua tau zoo - Lub zog ntawm FRPP yeeb nkab kub yaj interface yog siab dua li ntawm cov yeeb nkab lub cev, thiab qhov sib koom ua ke yuav tsis tawg vim av txav los yog thauj khoom.
Kev tsim kho kev ua tau zoo - cov raj xa dej yog lub teeb yuag, cov txheej txheem vuam yog yooj yim, kev tsim kho yooj yim, thiab tag nrho cov nqi tsim nyog yog tsawg.
