Xyoo 2023, kev lag luam thoob ntiaj teb ntawm cov tshuab cua compressor yog kwv yees li 44 billion daus las Asmeskas. Cov tuam txhab lag luam hauv Suav teb pheej txhim kho lawv lub peev xwm tsim khoom thiab qib kev tsim khoom, thiab cov txheej txheem hauv tsev pheej nce qib.Cov ntsiab lus lim cua compressor, raws li cov khoom siv tseem ceeb, nyob hauv txoj haujlwm tseem ceeb hauv cov saw hlau kev lag luam.
I. Cov Khoom Siv Raw Tseem Ceeb ntawm Cov Khoom Siv Lim Cua
Cov khoom siv tseem ceeb ntawm cov lim cua yog cov ntawv lim tshwj xeeb, uas nws qhov kev ua tau zoo ncaj qha txiav txim siab qhov cuam tshuam ntawm kev lim thiab lub neej ua haujlwm. Tam sim no, cov khoom siv lim cua tseem ceeb yog ua los ntawm cov tuam txhab HV xa tawm thiab cov ntawv lim ntoo Ahlstrom Kauslim Teb. Cov ntawv lim no muaj cov yam ntxwv hauv qab no:
Cov Kev Ntsuas Lub Cev: Qhov hnyav ntawm daim ntawv yog 127 ± 6 g/m², tuab ≥ 0.36 hli, qhov tob ntawm qhov corrugation 0.1 – 0.3 hli, qhov cua permeability ntawm △P = 200Pa mob ≥ 580L/m²·s, qhov loj tshaj plaws ntawm qhov pore ≤ 75μm.
Kev Ua Haujlwm Lim: Qhov tseeb ntawm kev lim yog 5 - 10μm, kev ua haujlwm lim dej ncav cuag 98%, zoo cuam tshuam cov khoom khov hauv huab cua. Cov qauv tsim ntau txheej pleated ua rau thaj chaw lim dej ntau dua 5 - 8 zaug, thiab lub peev xwm ua kom muaj kuab paug tau zoo dua.
Cov yam ntxwv ntawm kev ruaj khov: Lub neej ua haujlwm tus qauv yog 2000 teev, thiab nyob rau hauv ib puag ncig uas muaj huab cua zoo, nws tuaj yeem ntev mus txog 3000 teev. Daim ntawv lim dej yog kho nrog cov resin, nrog cov ntsiab lus resin ntawm kwv yees li 18%, muab nws zoo heev tiv taus dej thiab ruaj khov.
II. Cov Khoom Siv Raw Tseem Ceeb ntawm Cov Roj Lim Elements
Cov khoom siv lim roj yog cov khoom siv iav fiber. Nws cov yam ntxwv yog raws li nram no:
Cov Qauv Fiber: Siv cov iav fibers zoo heev nrog txoj kab uas hla ntawm 1 - 20μm, tsim ib txheej lim dej los ntawm cov qauv peb-seem interlaced, nrog qhov loj ntawm 30 - 80μm. Cov qauv no tuaj yeem cuam tshuam 99% ≥ 5μm roj tee dej, nrog rau kev ntsuas kev lim dej ntawm 99.9%.
Kev Ua Haujlwm Kub: Cov iav fibers lawv tus kheej tuaj yeem tiv taus 555 ℃ kub, tab sis thaum siv cov khoom lim, qhov kub ua haujlwm tuaj yeem ncav cuag 120 ℃ nyob rau hauv kev txhawb nqa ntawm stainless hlau thav duab. Nws muaj kev tiv thaiv tshuaj lom neeg corrosion muaj zog thiab tuaj yeem tiv taus cov kua qaub thiab alkali thiab lwm yam kev daws teeb meem tsis yog organic, tsim nyog rau kev lim ntawm ntau yam roj lubricating thiab roj hydraulic.
Cov Khoom Siv Kho Tshuab: Qhov kev tawg ntawm qhov ntev nce mus txog 3.5%, siab dua 42% piv rau cov txheej txheem ib txwm muaj.
III. Cov Khoom Siv Raw Tseem Ceeb ntawm Cov Khoom Siv Lim Sib Cais Roj-Roj
Cov khoom siv lim dej sib cais roj-roj siv cov khoom siv lim dej fiber ntau zoo heev los ntawm lub tuam txhab HV hauv Tebchaws Meskas. Lawv muaj cov yam ntxwv hauv qab no:
Cov Khoom Siv: Ua los ntawm cov khoom siv lim dej iav micrometer-level hauv cov qauv sib xyaw ua ke ntau txheej, nrog cov kab uas hla ntawm 1 - 20μm, tsim cov txheej lim dej peb-seem los ntawm cov txheej txheem tshwj xeeb. Cov qauv no tuaj yeem cuam tshuam cov roj av me me 0.1μm, nrog cov roj sib cais ntawm ≤ 3PPM w/w.
Lub Tshuab Sib Cais: Los ntawm kev cuam tshuam, kev sib kis thiab kev sib sau ua ke peb zaug, cov roj me me tau sib sau ua ke rau hauv cov roj loj. Cov roj av tau tso los ntawm cov yeeb nkab roj rov qab hauv qab thiab xa rov qab mus rau lub tshuab lubrication. Qhov sib txawv ntawm qhov siab pib yog ≤ 0.02MPa, qhov sib txawv ntawm qhov hloov pauv yog 0.7MPa, thiab lub neej ua haujlwm yog 3500 - 5200 teev.
Kev Hloov Pauv Ib Puag Ncig: Ua siab ntev rau pH 2 - 12 acidic thiab alkaline ib puag ncig, nrog rau qhov o ntawm ≤ 5%. Hauv 5000 lub voj voog kev sim, kev ua tau zoo tsuas yog poob qis los ntawm 12%, qhov siab ua haujlwm ntau ntawm 1.4 - 2.5MPa, tshwj xeeb tshaj yog haum rau cov chaw muaj kev lag luam hnyav xws li petrochemical thiab kev lag luam fais fab.
IV. Cov Khoom Siv Thib Ob thiab Cov Cheebtsam Pabcuam
Tus Neeg Sawv Cev Kho Resin: Cov resins no muab cov khoom siv lim dej rau cov khoom siv tiv thaiv dej, txhim kho lub zog kho tshuab, thiab txhim kho kev tiv taus kub. Phenolic resin tuaj yeem tiv taus 280 ℃, tswj kev ruaj khov ntawm qhov kub siab.
Cov Txheej Txheem Nplaum: Siv cov nplaum kub EVA, PO lossis PA rau kev sib dhos cov khoom lim. Cov khoom lim cua feem ntau siv cov nplaum kub EVA, thaum cov khoom lim roj siv PA polyurethane kub yaj nplaum. Cov nplaum no muaj viscosity ruaj khov ntawm qhov kub thiab txias thiab tsim cov txheej txheem sib txuas zoo tom qab kho, ua kom ntseeg tau tias cov qauv ntawm cov khoom lim muaj kev ncaj ncees. Cov khoom ntxiv ua haujlwm: suav nrog cov neeg sawv cev tiv thaiv dej, cov neeg sawv cev ua kom dawb, cov neeg tawg thiab cov neeg tiv thaiv hluav taws, thiab lwm yam.
Cov ntaub ntawv saum toj no ua haujlwm ua ke hauv ib lub tshuab los ua ke kom ntseeg tau tias cov khoom lim dej ua haujlwm tau zoo heev hauv kev lim dej raug, lub neej ua haujlwm thiab lub zog kho tshuab. Qhov sib piv meej ntawm cov ntaub ntawv sib txawv thiab cov txheej txheem ua haujlwm yog cov thev naus laus zis tseem ceeb.
