Nyob rau hauv xyoo tsis ntev los no, muaj kev xav tau zuj zus rauSaj zawg zog pob tshabCov yeeb yaj kiab uas tuaj yeem khoov duav lossis ua pwm rau hauv cov duab sib txawv kom tau raws li ntau yam kev lag luam ntau yam thiab thev naus laus zis. Cov yeeb yaj kiab no tau pom cov ntawv thov hauv kev lag luam xws li cov khoom siv hluav taws xob, nthuav tawm, hnub ci hlwb, thiab ntse ntim, ntawm lwm tus. Lub peev xwm ntawm cov yeeb yaj kiab no kom khoov tsis poob lawv lub pob tshab yog qhov tseem ceeb rau lawv txoj kev vam meej rau lawv txoj kev vam meej hauv cov ntawv thov no. Tab sis li cas ua tau ua cov yeeb yaj kiab no ua tau zoo li no?
Txhawm rau teb cov lus nug no, peb yuav tsum tau relve mus rau hauv kev sib xyaw thiab cov txheej txheem tsim qauv ntawm cov yeeb yaj kiab no. Cov yeeb yaj kiab uas yooj yim tshaj plaws yog tsim los ntawm cov polymers, uas yog cov saw ntev ntawm kev rov ua cov molecular chav. Qhov kev xaiv ntawm polymer khoom ua si lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov hloov thiab pob tshab ntawm zaj duab xis. Qee cov ntaub ntawv polymer polymer siv rau cov yeeb yaj kiab hloov tau muaj xws li polyethylene terepthalate (tsiaj), polyethylene naphthalate (cwj mem), thiab polyimide (PI).
Cov ntaub ntawv polymer no muaj cov khoom siv zoo tshaj plaws, xws li lub zog ua kom muaj zog thiab lub zog zoo ruaj khov, thaum tseem tswj lawv cov pob tshab. Txoj saw hlau ntawm polymer lwg me me tau ntim kom nruj thiab muab cov qauv muaj zog thiab coj mus rau zaj duab xis. Cov qauv kev ncaj ncees no tso cai rau cov zaj duab xis kom wring los khoov thiab molding yam tsis muaj tawg lossis ua pob tshab.
Ntxiv nrog rau kev xaiv ntawm cov polymer, cov txheej txheem tsim khoom tseem muaj pab txhawb rau qhov hloov pauv ntawm zaj duab xis. Zaj duab xis feem ntau yog tsim los ntawm kev sib xyaw ua ke ntawm extrusion thiab ncab cov tswv yim. Thaum lub sij hawm ua cov txheej txheem Extrusion, cov khoom siv polymer yog melted thiab yuam dhau los ntawm kev qhib me me hu ua kev tuag, uas ua rau nws mus rau ib daim nyias nyias. Daim ntawv no yog ces txias thiab sololified los tsim zaj duab xis.
Tom qab cov txheej txheem Extrusion, zaj yeeb yaj kiab yuav yauv mus rau ib kauj ruam ncab kom ntxiv txhim kho nws cov yooj yim. Ncab cuam tshuam nrog rub cov zaj duab xis nyob rau hauv ob txoj kev qhia ua ke, uas elongates cov saw polymer thiab ua kom raws li lawv cov kev taw qhia tshwj xeeb. Qhov txheej txheem ncab no qhia txog kev ntxhov siab no, ua rau nws khoov tau yooj yim thiab pwm tsis tau poob nws lub pob tshab. Cov qib ntawm kev ncab thiab kev coj ntawm kev ncab tuaj yeem hloov kho kom ua tiav qhov kev xav tau ntawm zaj duab xis.
Lwm qhov cuam tshuam uas cuam tshuam rau cov khoom muaj peev xwm ntawmSaj zawg zog cov yeeb yaj kiabyog lawv cov tuab. Thinner cov yeeb yaj kiab zoo li yoog tau ntau dua li cov tuab dua vim lawv txo qis los ntawm kev khoov. Txawm li cas los xij, muaj kev lag luam tawm ntawm cov tuab thiab siv tshuab zog. Thinner cov yeeb yaj kiab yuav yog ntau dua dhau los ntawm kev rhuav lossis puncture, tshwj xeeb yog raug rau cov mob hnyav. Yog li ntawd, cov tuam ntxhab yuav tsum tau ua kom zoo tshaj ntawm zaj duab xis raws li cov kev xav tau tshwj xeeb.
Sib nrug los ntawm cov tshuab ua haujlwm thiab cov txheej txheem tsim khoom, lub pob tshab ntawm zaj duab xis kuj yog nyob ntawm nws cov yam ntxwv saum toj. Thaum lub teeb sib cuam tshuam nrog cov yeeb yaj kiab saum npoo av, nws tuaj yeem cuam tshuam tau, kis, lossis nqus tau. Txhawm rau ua kom tiav pob tshab, cov yeeb yaj kiab feem ntau yog coated nrog nyias txheej pob tshab cov ntaub ntawv, xws li intrals cov ntaub ntawv, uas pab kom txo kev xav txog thiab txhim kho lub teeb kis. Cov txheej txheej no ua kom cov zaj duab xis tseem muaj pob tshab txawm tias thaum khoov duav lossis tuaj pwm.
Ntxiv rau lawv qhov yooj thiab pob tshab, hloov tau pob tshab cov yeeb yaj kiab tseem muab ob peb lwm qhov zoo dua cov khoom siv nruj. Lawv lub teeb yuag ua rau lawv zoo tshaj plaws rau cov ntawv thov uas qhov kev txo qhov hnyav yog qhov tseem ceeb heev, xws li hauv cov hluav taws xob portable. Ntxiv mus, lawv lub peev xwm los ua raws li cov chaw nkhaus ua rau cov qauv tsim ntawm kev tsim kho tshiab thiab chaw txuag hluav taws xob. Piv txwv li,Saj zawg zog cov yeeb yaj kiabsiv nyob rau hauv nkhaus qhia tawm, uas muab ntau qhov kev xav saib ntau dua.
Qhov xav tau nce ntxiv rauSaj zawg zog cov yeeb yaj kiabTau txais kev tshawb fawb thiab kev loj hlob hauv daim teb no, nrog cov kws tshawb fawb thiab cov kws tshawb fawb thiab cov khoom siv ua kom zoo dua los txhim kho lawv cov ntaub ntawv thiab lawv cov ntawv thov. Lawv tab tom ua haujlwm ntawm kev tsim cov ntaub ntawv tshiab polymer nrog txhim kho kom tau yooj yim thiab muab cov txheej txheem tshiab tsim kom ua tiav cov nqi luam hluav taws xob. Raws li qhov tshwm sim ntawm cov kev siv dag zog no, lub neej yav tom ntej zoo li muaj kev cia siab rauSaj zawg zog cov yeeb yaj kiab, thiab peb tuaj yeem cia siab tias yuav pom cov ntawv thov tshiab hauv ntau qhov kev lag luam.
Hauv kev xaus, qhov hloov pauv ntawm pob tshab cov yeeb yaj kiab yog ua tiav los ntawm kev xaiv cov khoom siv, cov yeeb yaj kiab ua kom huv, thiab nws cov yam ntxwv saum npoo av. Cov ntaub ntawv Polymer nrog cov kws kho tshuab ua kom zoo nkauj tso cai rau cov yeeb yaj kiab kom wrutolt ntog yam tsis muaj kev hloov pob tshab. Cov txheej txheem tsim khoom lag luam cuam tshuam nrog kev sib txuas thiab ncab kom txhim kho ntxiv kom yooj yim. Txheej thiab txheej nyias nyias yog thov kom txo rov qab los thiab txhim kho lub teeb kis. Nrog kev tshawb fawb tsis tu ncua thiab kev txhim kho, yav tom ntej ntawmSaj zawg zog cov yeeb yaj kiabZoo li ci, thiab lawv tau teeb tsa los daws cov kev lag luam thiab thev naus laus zis hauv ntau txoj kev.
