Cov fwj iav tuaj yeem hais tias yog lub thawv uas siv ntau heev hauv tib neeg lub neej txhua hnub. Lawv yooj yim siv, huv si thiab huv si, zoo nkauj thiab DIY. Tab sis nws kuj muaj qhov tsis zoo. Hnub no, peb yuav coj txhua tus mus saib seb muaj qhov tsis zoo dab tsi hauv cov fwj iav.
Qhov tsis zoo ntawm lub raj mis iav muaj ob pawg: macroscopic thiab microscopic. Yog hais meej meej, qhov tsis zoo macroscopic feem ntau yog qhov tsis zoo uas tuaj yeem pom ncaj qha, thaum qhov tsis zoo microscopic yog qhov tsis zoo uas tsis tuaj yeem pom nrog lub qhov muag liab qab, thiab tsuas yog tuaj yeem vam khom kev tshuaj xyuas thiab kev tshuaj xyuas ntawm cov cuab yeej kuaj, thiab qhov tsis zoo tseem ceeb ntawm lub raj mis iav tuaj yeem nkag siab raws li cov txiaj ntsig ntawm kev xeem.
Qhov tsis zoo ntawm lub raj mis iav kuj tseem tuaj yeem muab faib ua ob pawg: qhov tsis zoo ntawm kev daws teeb meem thiab qhov tsis zoo ntawm kev tsim khoom raws li lawv qhov ua rau.
Qhov tsis zoo ntawm lub cev lub raj mis, raws li lub npe qhia, xa mus rau qhov tsis zoo ntawm cov kua iav laminated nws tus kheej, xws li npuas, pob zeb zis, cov qauv, crystallization, xim cam khwb cia, thiab lwm yam. Qhov laj thawj rau qhov tsis zoo no feem ntau yog vim qhov kub ntawm cov kua iav thiab pwm tsis tau mus txog qhov kub thiab txias ib txwm muaj.
Vim tias lub sijhawm no yog cov txheej txheem ntawm kev ua kom sov lub pwm, thiab tseem yog cov txheej txheem ntawm kev debugging lub pwm thiab lub tshuab, lub raj mis tsim tawm thaum lub sijhawm no yuav muaj ntau yam teeb meem, xws li npuas, cov qauv, tawg, thiab lwm yam. Yog li ntawd, peb lub tuam txhab yuam kom txhua yam khoom tsim tawm hauv li 2 teev thaum ntxov yuav raug rhuav tshem.
Hais meej meej, qhov tsis zoo ntawm kev tsim khoom yog hais txog qhov tsis zoo ntawm lub raj mis iav hauv tag nrho cov txheej txheem ntawm kev tsim khoom, xws li tawg, me me tawg, khawb, deformation, qhov yuam kev specification, qhov txias, wrinkles, streamlined waves, stickiness Die, luam tawm, hluav taws kub, kev ua qias tuaj ib puag ncig thiab ntau yam kev tsim kho kom zoo nkauj. Feem ntau, qhov tsis zoo no yog vim qhov tsis zoo pom, thiab qhov tseem ceeb rau qhov tsis zoo pom (macroscopic defects) yog hais txog qhov sib npaug ntawm cov iav laminated, qhov kev ntxhov siab quenching, kev ntseeg tau ntawm cov organic chemistry, thiab kev tiv thaiv rau qhov kub siab hloov pauv sai.
Qhov tsis zoo ntawm cov tsos feem ntau cuam tshuam rau qhov zoo nkauj ntawm cov khoom thiab qhov siv tiag tiag, thaum qhov tsis zoo loj heev yuav ua rau qhov zoo ntawm cov khoom muaj kev phom sij. Muaj ntau yam tsis zoo ntawm cov fwj iav, thiab muaj ntau yam ua rau. Qee zaum rau qee qhov tsis zoo, muaj ntau yam ua rau, tab sis hauv kev xaus, lawv txhua tus muaj feem cuam tshuam nrog cov txheej txheem interlayer. Tag nrho cov txheej txheem tsim khoom ntawm iav muaj feem cuam tshuam rau tag nrho cov txheej txheem. Yog li ntawd, thaum tshuaj xyuas qhov tsis zoo ntawm cov khoom iav kom ntxaws, nws tsis tas yuav kho qee qhov tsis zoo hauv kev cais tawm, tab sis kom nkag siab txog kev hloov pauv ntawm cov qauv tsim khoom nyob ib puag ncig pem hauv ntej thiab tom qab thaum qhov tsis zoo ntawm cov iav laminated tshwm sim.
Ua ntej tshaj plaws, tswj hwm tag nrho cov txheej txheem ntawm cov txheej txheem ntau lawm, thiab sim zam kom tsis txhob muaj qhov tsis zoo. Ntau hom kev tsis zoo muaj ntau txoj kev tshawb fawb sib txawv. Thaum muaj qee hom kev tsis zoo tshwm sim hauv cov iav laminated, feem ntau nws yog qhov tsim nyog los siv ntau txoj hauv kev los tshawb fawb txog kev tshawb fawb kom paub qhov txawv ntawm ntau yam. Raws li kev nrhiav pom qhov laj thawj, peb ua cov kauj ruam tam sim ntawd los tiv thaiv kev rov tshwm sim ntawm qhov tsis zoo.
Qhov saum toj no yog hais tias cov fwj iav uas tus kws kho xov xwm hauv internet tau muab rau txhua tus muaj qee qhov tsis zoo, tab sis raws li cov ntsiab lus ntawm tsab xov xwm, tib neeg kuj tuaj yeem pom tias cov kev tsis zoo no tuaj yeem tiv thaiv tau, uas kuj hais tias cov neeg ua haujlwm tsim khoom rov ua dua tag nrho cov txheej txheem Tsuas yog yuav tsum ceev faj ntxiv.
