Khaws rau hauv qhov chaw txias, qhuav, tsis txhob los nag, noo noo, tshav ntuj, hluav taws. Nws yog nruj me ntsis txwv tsis pub tiv tauj lossis sib xyaw nrog cov khoom siv acid thiab alkali.
Daim ntawv thov:
MPP non-excavation power pipe granular foaming agent yog ib qho kev hloov kho additive tsim tshwj xeeb rau MPP (hloov polypropylene) uas tsis yog- excavation power pipeline production. Txais daim ntawv granular, nws nta zoo heev fluidity thiab uniform dispersion nyob rau hauv MPP resin, tsis txhob muaj plua plav paug thiab sib tov tsis sib xws thaum lub sij hawm tsim khoom, kom ntseeg tau ruaj khov extrusion thiab kev ua haujlwm tsis tu ncua.
Cov foaming tus neeg sawv cev no muaj qhov tsim nyog decomposition kub sib xws MPP ua cov txheej txheem, tso pa roj maj mam thiab sib npaug los ua kom compact, kaw -cell microstructures hauv cov yeeb nkab. Such a structure effectively reduces overall material density and achieves obvious lightweight effect, making transportation, handling and non-excavation laying easier while lowering raw material consumption and production costs.
Ib qho txiaj ntsig tseem ceeb yog nws qhov kev txhim kho zoo kawg nkaus hauv lub nplhaib nruj ntawm MPP cov kav dej. Lub cev tsis sib xws ntawm lub cev muaj zog ntxiv dag zog rau cov yeeb nkab sab hauv kev txhawb nqa, txhim kho compression tsis kam, creep kuj thiab sab nraud load bearing muaj peev xwm. Txawm tias nyob rau hauv ntev - lub sij hawm faus siab thiab geological deformation, lub raj xa dej tswj kev ncaj ncees yam tsis muaj kev tawg lossis tawg, ua tau raws li cov qauv kev tsim vaj tsev nruj heev rau tsis yog - khawb khawb.
Tsis tas li ntawd, nws pab txhim kho qhov chaw tiaj tus thiab qhov chaw ruaj khov, tshem tawm qhov tsis xws luag xws li npuas, qhov thiab warping. Cov yeeb nkab foamed tswj kev ua haujlwm zoo rwb thaiv tsev thiab tshuaj tiv thaiv corrosion, yoog mus rau qhov chaw hauv av. Cov khoom no tsis muaj ntxhiab tsw, ib puag ncig tus phooj ywg thiab nyab xeeb rau cov neeg ua haujlwm.
Nrog rau cov txheej txheem muaj zog adaptability, nws yog dav siv nyob rau hauv ntau yam MPP tsis yog - excavation hwj chim yeeb nkab extrusion kab. Los ntawm kev ntsuas lub nplhaib siab nruj thiab lub teeb yuag, nws txhim kho cov khoom zoo thiab txuas ntxiv lub neej kev pab cuam, ua rau nws yog ib qho tseem ceeb ntxiv rau siab -kev ua tau zoo MPP lub raj xa dej.
Haum rau MPP cov kav dej fais fab, PE cov kav dej hauv nroog, thiab cov khoom lag luam uas xav tau ntau- txheej co-extrusion.
