Kev ua yeeb yam thiab siv cov kauj ruam ntawm cov nplaum nplaum
Txhua txheej ntawm nplaum nplaum yog coated nrog ib tug high-viscosity tshwj xeeb los yog low-viscosity adhesive viscosity tus neeg sawv cev rau ntau qhov chaw. Cov ntawv sau qhia tau yooj yim sib cais ntawm daim ntawv thiab daim ntawv. Lub plhaub nplaum, txheej txheem nplaum ncaj nraim tuaj yeem ceev nrooj thiab tshem tawm cov plua tshauv uas nqa los ntawm lub log thiab ib qho ntawm lub tsheb, ua kom thaj chaw huv, yooj yim siv, ntom ntim paug, thiab txheej pov tseg. Kev hnav, yooj yim los nqa thiab ceev nrooj thiab tshem tawm hluav taws xob hluav taws xob hauv qhov dav dav.
Tib lub sij hawm, qhov tseemceeb tshaj plaws yog qhov nplaum nplaum yog tsim rau kev nkag mus lossis qhov tsis zoo nyob qhov twg uas yuav tsum tau siv qhov chaw tsis muaj kev tsis zoo. Nws muaj peev xwm tshem tawm cov plua plav ntawm lub xuab zeb thiab lub log, thiab txo cov plua plav mus rau qhov zoo ntawm lub zais hluav taws xob. Cov nyhuv no yog ua kom tiav cov kev ua kom yooj yim plav plooj, thiab daws qhov teeb meem uas plua plav tawm ntawm lwm cov pem teb plag yog tsis tag tsis pom meej kom cov hmoov av tsis nthuav.
Crack elongation coefficient; lwm qhov sib zog ua kom muaj zog; nro; tsevneeg lub zog; nruab nrab, siab, qis, thiab lwm yam. Qhov saum toj no yog ib txoj hauv kev yooj yim rau kev nkag siab txog qee yam tshwj xeeb ntawm cov nplaum nplaum los ntawm ib qho. Nws tseem yuav to taub los ntawm lwm cov ces kaum sib txawv.
Ua ntej, tshem cov txheej txheem ntawm cov roj hmab ntawm qhov qhib rau sab nraum qab, ces muab tso rau hauv qhov huv si thiab tsis tso dej hauv av, thiab siv tib lub plhaub nplaum nplaum los rau hauv av thiab tom qab ntawd los ntawm qhov qhib ntawm lub xub ntiag . Qhov kev tiv thaiv qis dua, yog li ntawd nws yuav siv tau (yog hais tias cov nplaum ntawm cov yeeb yaj kiab puv ntawm cov hmoov av thaum siv, txheej yuav raug muab tshem tawm ntawm qhov qhib, ces tom qab txheej txheej ntawm zaj duab xis yuav siv tau), thawj kauj ruam yuav pom. Thiab qhov thib peb kauj ruam yog los tev tawm ntawm lub teeb ci, uas yog dab tsi peb hu rau kev tiv thaiv txheej txheem. Cov txheej txheem tiv thaiv yog siv los tiv thaiv cov nplaum nplaum los ntawm kev ntxuav ua ntej nws siv. Ntxiv rau qhov txheej txheem tiv thaiv, txhua txheej yuav cim nrog 1, 2, 3, 4 .... 30 nyob rau ntawm cov ces kaum, kom tus neeg tuaj yeem hloov tau rau ib txheej tshiab tom qab txheej txheej plua plav.
