Kev tiv thaiv kev laus ntawm cov khoom siv yas, tshwj xeeb tshaj yog kev tiv thaiv kev laus ntawm cov khoom xws li cov hnab ntim khoom, tau nyob hauv cov lag luam woven. Kev siv cov txheej txheem kev laus tau kawm. Yog tias siv tau zoo, nws tuaj yeem ua ob npaug ntawm tus nqi ntawm cov khoom tom kawg ntawm lub tsev. Sawv cev Jixing tau them nyiaj los ntawm cov neeg nplua nuj. Kev tiv thaiv kev laus muaj ntau yam kev qhuab qhia xws li polymer chemistry, polymer physics, thiab cov ntaub ntawv yas engineering. Kev tsom xam thiab kev kho cov teeb meem nyuaj hauv tshooj no tau mob siab rau los teb cov teeb meem nyuaj no los ntawm kev xav ntawm kev xav thiab kev xyaum. Nyob rau hauv tshooj no, ntau tus qauv txhim khu kev qha rau kev tiv thaiv kev laus ntawm cov khoom yas kawg tau muab.
Vim li cas cov ntaub ntawv yas woven thiab cov khoom muaj hnub nyoog?
Cov ntaub ntawv yog tag nrho cov ntaub ntawv polymer, thiab cov ntaub ntawv polymer yuav inevitably poob mus tas li thaum lawv synthesis, tsheb thauj mus los, cia, ua thiab cov txheej txheem khoom kawg, thiab lawv cov kev ua tau zoo ntawm lub cev yuav poob qis, uas yog, kev laus. Kev ua haujlwm ntawm kev laus xws li yellowing, poob ntawm luster, nto tawg ntawm cov khoom, chalking (polypropylene), thiab hnyav dua, cov khoom siv xws li tensile zog, cuam tshuam lub zog, flexural zog thiab elongation ntawm tawg yog zoo heev txo, yog li poob. Siv kev ua haujlwm.
Los ntawm cov tshuaj lom neeg pom, tsis hais seb cov khoom siv polymer yog ntuj lossis hluavtaws, vim nws cov qauv macromolecular saw, qee qhov ntawm nws muaj qee qhov tsis muaj zog, thiab cov nyiaj tsis muaj zog no dhau los ua cov tshuaj tiv thaiv. Kev laus ntawm cov yas woven raw cov ntaub ntawv thiab cov khoom yog tsis muaj dab tsi ntau tshaj li tej yam ntuj tso tej yam kev mob, pib los ntawm tsis muaj zog daim ntawv cog lus los ua cov tshuaj tiv thaiv, xws li oxidation cov tshuaj tiv thaiv, thiab yog li ua rau ib tug series ntawm lwm yam tshuaj. Raws li qhov tshwm sim, cov qauv molecular ntawm cov khoom siv polymer hloov pauv, xws li kev sib tsoo ntawm cov saw hlau, qhov txo qis ntawm cov txheeb ze molecular hnyav los yog kev sib txuas, uas ua rau cov khoom ua haujlwm tsis zoo thiab ua rau nws siv tsis tau.
Muaj ntau yam tseem ceeb rau kev laus ntawm cov yas woven raw cov ntaub ntawv thiab cov khoom, xws li tshav kub, ultraviolet lub teeb, cua, Frost, daus thiab los nag, thiab lwm yam.Plastic woven khoom siv ntau yam aging, xws li lub sij hawm ntev load, stacking extrusion. quab yuam, thiab ntau yam tshuab sab nraud. , Electrostatic quab yuam thiab corrosion ntawm cov ntsiab lus, thiab lwm yam.
Kev laus tshaj plaws tuaj yeem muab faib ua ob pawg: thermal oxidative laus thiab photooxidative laus. Muaj qhov kub thiab txias, thiab nrog cov pa oxygen hauv huab cua, muaj thermal oxygen aging; Thaum muaj lub teeb, uas yog, ultraviolet hluav taws xob, thiab nrog cov regas hauv huab cua, muaj photooxygen aging. Thaum lub sij hawm tag nrho cov txheej txheem ntawm kev khaws cia, kev thauj mus los, kev ua thiab siv, feem ntau raug tshav kub, oxygen thiab hnub ci (ultraviolet rays) nyob rau hauv ib puag ncig.
Cov lag luam yas woven yuav tsum nco ntsoov tias cov pellets ntawm cov yas woven polypropylene raw cov ntaub ntawv tau muab ntxiv nrog ib tug chemical agent thaum lub sij hawm tsim khoom. Cov chaw tsim tshuaj paus tau lees paub tias yuav tsis muaj kev laus loj thaum lub sijhawm tsim khoom, khaws cia thiab kev thauj mus los. Txawm li cas los xij, cov hmoov tsis ntxiv nrog cov tshuaj tiv thaiv kev laus, thiab cov yas braiding lag luam yuav tsum tsis txhob khaws nws ntev dhau, vim tias cov txheej txheej ntawm cov hmoov yuav muaj hnub nyoog tiag tiag nrog lub sijhawm cia. , Polyethylene siv hauv cov ntaub ntawv yas, feem ntau tsis tas yuav xav txog kev khaws cia thiab kev thauj mus los.
