Dab tsi yog qhov tseem ceeb uas yuav tau txiav txim siab thaum xaiv cov khoom haum khi rau daim ntawv thov?
Lub Sij Hawm Zoo Tshaj Plaws thiab Tsim Nyog Xim
Qhov tsim nyog ntawm ntsaws ruaj ruaj
Txhua qhov cuam tshuam hauv qhov kev sib khi: piv txwv li qhov kub thiab txias, kua dej thiab lub siab
Cov no yog txhua yam tseem ceeb los xav txog hauv koj lub kaw lus sib khi. Yog tias txhua yam ua rau paub, nws yuav yooj yim rau xaiv cov khoom tsim nyog.
Txawm li cas los xij, qhov kev zam ua ntej yog tias cov khoom siv yuav tsum ua kom ruaj khov. Yog li ntawd, thawj qhov uas yuav tau xav txog yog qhov ua tau zoo ntawm kev ua haujlwm. Cia peb pib nrog cov ntsiab yam ua tau zoo.
Cov kev pabcuam lub neej thiab nqi ntawm cov kab ke yog qhov tseem ceeb uas yuav tau txiav txim siab. Tag nrho lwm yam yuav cuam tshuam rau koj daim ntawv thov kev ua haujlwm. Nws yog ib qho tseem ceeb heev uas yuav tau xav txog qhov kev tsim qauv raws li daim ntawv thov. Qhov no suav nrog cov ntaub ntawv siv, kho vajtse cov duab thiab cov txheej txheem ntau lawm. Nyob rau tib lub sijhawm, muaj cov xwm txheej ib puag ncig yuav tau txiav txim siab, suav nrog siab, kub, sijhawm, sib dhos thiab nruab nrab.
Txhawj Xeeb
Elastomers tau nrov vim tias lawv qhov zoo elasticity. Lub elasticity ntawm lwm yam ntaub ntawv tsis tuaj yeem ncav rau tib theem.
Elastomer rov qab siv dua yog qhov nyuaj thiab kim. Lwm cov ntaub ntawv xws li polyurethane thiab cov khoom siv thermoplastic muaj ntau qhov kev coj tus kabmob siab ntau dua li elastomers.
Cov ntaub ntawv siv roj hmab tuaj yeem siv ntau qhov sib txawv.
Cov yam ntxwv tseem ceeb muaj xws li
. Elastic
Ness hardness
● Lub zog tawv
Lwm qhov tseem ceeb muaj xws li
● compression teeb
Tshav kub ua hauj
● tsawg kub hloov tau
Kev sib txuam nrog tshuaj
● Laus kuj tiv taus
Ras Abrasion tsis kam
Tus yam ntxwv tseem ceeb tshaj plaws yog kev ywj pheej ntawm cov khoom siv roj hmab. Cia peb kawm ntxiv txog qhov no.
Elasticity yog txiaj ntsig ntawm vulcanization. Cov ntaub ntawv elastomeric, xws li cov roj hmab vulcanized, yuav rov qab mus rau lawv qhov qub qub yog tias deformed.
Cov khoom tsis zoo, xws li cov roj hmab tsis ruaj khov, tsis tuaj yeem rov qab mus rau lawv lub xeev qub yog tias hloov lawm. Vulcanization yog txheej txheem ntawm hloov cov roj hmab rau hauv cov khoom siv elastomer.
Kev xaiv ntawm elastomer feem ntau yog ua raws:
● kev khiav hauj lwm kub ntau
● Ua kua thiab roj tsis kam
Kev tiv thaiv huab cua hloov kho, nws thiab nws dhau los
