PU rwb thaiv tsev yeeb nkab yog nrov heev vim lawv cov kev ua tau zoo, kev tsim kho yooj yim, thiab kev pab lub neej ntev (30-50 xyoo). Lawv cov qauv muaj peb ntu: txheej txheej tiv thaiv, txheej rwb thaiv tsev, thiab txheej tiv thaiv to. Cov khoom siv tiv thaiv sab nrauv yog polyethylene tsho yeeb nkab, fiberglass, lossis lwm yam ntaub ntawv. Muaj peb txoj hauv kev tso: ncaj qha faus, nyiaj siv ua haujlwm, thiab trench.
Thawj txheej: ua haujlwm steel yeeb nkab txheej
Seamless steel kav, kauv steel kav, thiab ncaj seam steel kav feem ntau xaiv raws li tus qauv tsim thiab cov neeg siv khoom. Tom qab qhov saum npoo ntawm cov yeeb nkab steel raug kho nrog kev txhaj tshuaj tiv thaiv qib siab thiab kev tshem tawm xeb, qib kev tshem tawm xeb ntawm cov yeeb nkab steel tuaj yeem ncav cuag qib Sa2 hauv GB / T8923-1988 tus qauv, thiab qhov roughness tuaj yeem ncav cuag R{ {2}}.5 micrometers hauv GB6060.5-88 tus qauv.
Ob txheej: Polyurethane rwb thaiv tsev txheej:
Sib tov cov ntaub ntawv polyurethane dub thiab dawb nrog lub tshuab ua npuas siab siab thiab txhaj tshuaj ntawm cov yeeb nkab steel thiab cov yeeb nkab tiv thaiv sab nrauv los tsim cov txheej txheem polyurethane, feem ntau hu ua "pipe hauv yeeb nkab foaming".
Peb txheej: high-density polyethylene tiv thaiv txheej:
Prefabricated dub los yog daj polyethylene yas kav nrog ib tug tej phab ntsa thickness. Polyethylene tsis muaj ntxhiab tsw, tsis muaj tshuaj lom, siv quav ciab zoo li hauv tes, muaj qhov kub thiab txias tsis zoo, kev siv qis tuaj yeem ncav cuag - 70 ~ - 100 degree, kev ruaj ntseg tshuaj zoo, tuaj yeem tiv taus kev yaig ntawm feem ntau cov kua qaub thiab alkalis. (tsis resistant rau oxidizing acids), insoluble nyob rau hauv cov kuab tshuaj nyob rau hauv lub chav tsev kub, tsis tshua muaj dej nqus, tab sis vim hais tias nws yog ib tug linear molecule, nws muaj peev xwm maj mam yaj nyob rau hauv ib co organic solvents, tsis o, thiab muaj zoo hluav taws xob rwb thaiv tsev kev ua tau zoo. Nws txoj haujlwm yog los tiv thaiv polyurethane rwb thaiv tsev txheej los ntawm kev puas tsuaj, thiab tiv thaiv corrosion thiab waterproofing.
Tsis tas li ntawd, PU rwb thaiv tsev cov kav dej tuaj yeem nruab nrog cov kab hluav taws xob xau los qhia cov neeg ua haujlwm kom pom cov dej xau sai sai ntawm cov kav dej xau, kom ntseeg tau tias kev ua haujlwm ntawm cov cua sov network.
