Hauv cov kua dej hloov pauv, hoses ua haujlwm tseem ceeb ntawm cov khoom siv thiab kev tshaj tawm, thiab lawv qhov kev ua tau zoo cuam tshuam ncaj qha rau kev ruaj ntseg thiab kev nyab xeeb ntawm lub cev PTFE hoses thiab PVC hoses, raws li ob hom khoom siv hose, txhua tus muaj qhov tshwj xeeb zoo thiab kev siv. Kev nkag siab txog qhov sib txawv ntawm lawv tuaj yeem pab peb xaiv qhov tsim nyog raws li qhov xav tau tiag tiag.
- Tshuaj muaj pes tsawg leeg thiab stability
Lub PTFE hose yog ua los ntawm cov khoom siv polytetrafluoroethylene, uas muaj tshuaj lom neeg ruaj khov thiab yuav luag tsis muaj kev cuam tshuam los ntawm cov khoom siv. Nws tuaj yeem tiv thaiv kev tawm tsam ntawm corrosive media xws li acids, alkalis, thiab ntsev. Nws cov qauv molecular tsis muaj carbon-carbon ob daim ntawv cog lus yog li nws muaj oxidation siab. Hauv qhov sib piv, PVC hose yog cov khoom siv hluavtaws polymerized los ntawm cov yas chloride monomers. Txawm hais tias nws kuj muaj kev tiv thaiv zoo corrosion nws cov tshuaj lom neeg ruaj khov thiab oxidation kuj tseem qis dua. Qhov sib txawv no ua rau PTFE hose muaj txiaj ntsig zoo dua nyob rau hauv ib puag ncig corrosive heev.
- Cov yam ntxwv ua haujlwm
PTFE hoses ua tau zoo sib npaug ntawm kev ua haujlwm. Lawv cov phab ntsa sab hauv yog du nrog kev sib txhuam coefficient tsawg, uas tuaj yeem txo qhov kev tiv thaiv lub sijhawm thiab txo cov khoom hnav. Tsis tas li ntawd, PTFE hoses muaj qhov ua tau zoo thiab qhov kub thiab txias tsis kam, ua rau lawv ua haujlwm ruaj khov nyob rau hauv qhov kub thiab txias ntau yam -250 ℃ to 260 ℃ yam tsis muaj nkig lossis laus. Ntawm qhov tod tes, PVC hoses, thaum muaj qee qhov hloov tau yooj yim thiab tensile, nws yooj yim rau deformation ntawm qhov kub thiab txias, txwv lawv siv nyob rau hauv qhov kub thiab txias.
PTFE hoses, vim lawv cov tshuaj zoo heev ruaj khov, kub tsis kam, thiab hnav tsis kam, yog siv dav hauv kev lag luam xws li tshuaj lom neeg, roj nkev, khoom noj khoom haus, thiab tshuaj uas yuav tsum tau ua haujlwm siab. Lawv yog tshwj xeeb tshaj yog haum rau tuav corrosive media thiab high-pressure ib puag ncig. Ntawm qhov tod tes, PVC hoses, nrog rau lawv cov nqi qis thiab kev ua haujlwm zoo, tau siv dav hauv kev tsim kho cov dej, qhov cua, cov dej xa dej, nrog rau cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob uas tsim nyog rau kev txhim kho thiab tswj tus nqi. Muaj qhov sib txawv tseem ceeb hauv cov khoom siv thiab daim ntawv thov ntawm ob qho tib si.
Nyob rau hauv xaus, peb ib zaug ntxiv hais txog qhov uniqueness thiab complementarity ntawm ob cov ntaub ntawv hose. PTFE hoses, nrog lawv cov tshuaj zoo heev ruaj khov tsis muaj kev sib txhuam coefficient, thiab tsis kam mus rau qhov kub thiab txias, tau dhau los ua cov khoom siv rau high-end manufacturing thiab huab cua ua haujlwm. Ntawm qhov tod tes, PVC, nrog rau lawv cov nqi-zoo thiab yooj yim ntawm kev ua, tau pom lawv qhov chaw nyob rau hauv ntau yam kev lag luam. Qhov kev xaiv ntawm cov hose siv tsis yog tsuas yog kev txhawj xeeb-kev ua tau zoo tab sis kuj yog tag nrho cov kev ua tau zoo thiab kev nyab xeeb ntawm qhov system.
