Raws li kev nce qib ntawm cov thev naus laus zis thiab kev txhim kho ntawm kev lag luam roj hmab, cov khoom siv rau cov kav dej siab tau muab faib ua ob pawg: cov ntaub ntawv tsis yog xim hlau thiab cov khoom siv hlau. Cov ntaub ntawv uas tsis yog xim hlau feem ntau siv los tsim cov hoses siab muaj xws li NBR, NBR, TBR, thiab lwm yam. EPDM roj hmab, chlorosulfonated polyethylene, chloroether roj hmab, NBR thiab lwm yam khoom tau maj mam siv rau cov khoom ntawm high-pressure hose manufacturers. .
High-pressure hose cov khoom siv rau kev tsim cov khoom ua haujlwm siab, cov khoom muaj nqis ntxiv. Cov khoom siv tsis yog xim hlau muaj xws li nylon, fiber ntau, thiab lwm yam. Nrog rau kev txhim kho ntawm kev lag luam textile, cov ntaub ntawv ua tau zoo xws li aramid tau maj mam siv rau cov hoses siab.
Copper-plated steel hlau thiab galvanized steel hlau yog tag nrho cov khoom siv hlau puag ncig, thiab cov khoom siv pob txha pob txha tau txhim kho txuas ntxiv nrog kev txhim kho hauv computer simulation, kev sim thiab lwm yam thev naus laus zis. Pav ca hlau (tiaj tus hlau yog oval tooj liab-plated steel hlau) yuav siv tau rau high-pressure hoses.
Cov ntaub ntawv tshiab rau siab siab hoses:
(1) EPDM ternary roj hmab Eli: Nws muaj kev ua haujlwm kub zoo, ua haujlwm tsis zoo, kub kub aging kuj, tshuaj corrosion kuj thiab zoo hluav taws xob rwb thaiv tsev zog, tshwj xeeb tshaj yog haum rau glycol ether nres kua thiab zaub roj. Nws yog siv los tsim cov hoses siab siab uas tiv taus qhov kub thiab txias, chav thiab corrosive media.
(2) Chlorosulfonated polyethylene roj hmab: Nws muaj ozone zoo heev thiab tuaj yeem tiv taus huab cua. Nws muaj cov tshuaj tiv thaiv zoo, nplaim taws ua haujlwm zoo, tiv thaiv roj thiab tsim kua muag. Nws yog qhov tsim nyog rau kev ua cov hoses siab siab uas tiv taus cov xov xwm muaj zog corrosive, nplaim hluav taws, thiab ozone-resistant aging, tshwj xeeb tshaj yog rau kev ua cov txheej txheej ntawm cov roj hmab hoses rau siv nyob rau hauv hnyav atmospheric ib puag ncig.
(3) Chloroether roj hmab: Nws muaj lub hnub tiv thaiv zoo heev. Roj kuj, hnyav kuj. Nws muaj cov nplaim hluav taws zoo thiab huab cua permeability, thiab tsim nyog rau kev tsim cov roj-resistant, ozone-resistant, high-temperature-resistant thiab low-permeation high-pressure hoses.
(4) Hydrogenated nitrile roj hmab: Nws muaj cov khoom zoo xws li roj tsis kam, corrosion kuj, tsis kub, oxidation kuj, dynamic qaug zog, thiab ozone kuj. Nws yog tsim rau kev tsim cov hoses siab siab nrog cov roj ua haujlwm siab.
(5) NBR / PVC: zoo heev roj tsis kam, puas kuj thiab ozone kuj. Nws muaj qhov zoo extrudability thiab kev ua haujlwm yooj yim, thiab tsim nyog rau txheej txheej sab nraud ntawm cov kav dej siab siv rau hauv qhov chaw hnav-resistant thiab ozone-resistant.
(6) Aramid fiber ntau: Aramid fiber muaj cov khoom zoo xws li lub zog super, siab modulus, kub tsis kam, acid thiab alkali tsis kam, thiab lub teeb yuag, thiab nws lub zog yog 7 npaug ntawm cov fibers zoo tib yam. Nws modulus yog 2-3 npaug ntawm cov iav fiber ntau lossis hlau hlau. Lub toughness yog 2 zaug siab dua qhov qub, thiab qhov zoo tsuas yog 1/5 ntawm qhov qub. Nws tsis decompose los yog yaj ntawm qhov kub ntawm 450 ° C, thiab muaj cov rwb thaiv tsev zoo thiab kev laus ua haujlwm. lub neej ntev
(7) Flat steel: Nws muaj cov yam ntxwv ntawm lub zog siab, siab modulus, kub tsis kam, khoov tsis kam thiab siab ua haujlwm. Tshwj xeeb tshaj yog torsion kuj thiab khoov deformation kev ua tau zoo. Kev kub siab ntev lub raj braids / cov raj ntev ua los ntawm cov kav ntev ntev muaj cov mem tes zoo dua li cov raj ntev ua los ntawm lub zog siab (ultra siab zog) cov raj ntev.
