Tam sim no, cov khoom siv hauv kev lag luam muaj xws li cov khoom siv rov ua dua qub, cov khoom siv hluav taws xob engineering, thiab cov khoom siv hlau. Txawm hais tias cov khoom siv rov ua dua qub yog pheej yig dua, lawv yooj yim rau stripping, cracking, los yog laus thiab embrittlement nyob rau hauv ntev - lub sij hawm load los yog rov kho dua, tshwj xeeb tshaj yog nyob rau hauv cov pob qij txha thiab kev ntxhov siab. Cov teeb meem no tuaj yeem ua ncaj qha rau cov txheej txheem loosening, yog li cuam tshuam rau kev nyab xeeb.
Nyob rau hauv sib piv, engineering plastics xws li nylon (PA) thiab polyoxymethylene (POM) pom zoo hnav tsis kam, creep resistance, thiab dimension stability. Piv txwv li, kev hloov kho pob qhov rooj thiab lub zog ua los ntawm cov khoom siv POM muaj zog tiv thaiv cov khoom uas ua kom cov rooj zaum thiab cov rooj zaum muaj qhov tseeb thiab ruaj khov tom qab ntau qhov kev hloov kho qhov siab, ua rau lawv lub neej ntev.
Tsis tas li ntawd, siv cov hlau-cov khoom siv yas sib xyaw hauv cov khoom tseem ceeb- cov kabmob sib txuas tuaj yeem txhim kho kev ua tau zoo. Piv txwv li, pre-embedded hlau threaded lub tes tsho ntawm cov ntsia hlau sib txuas tuaj yeem tiv thaiv cov xov yas los ntawm kev hnav thiab stripping vim rov ua dua, yog li txuas ntxiv cov khoom lag luam kom ruaj khov.
Ntxiv nrog rau kev xaiv cov khoom siv, kev tsim khoom siv kuj yuav tsum xav txog kev hloov pauv ib puag ncig. Cov ntaub ntawv nrog cov huab cua tsis zoo yog qhov ua rau deformation nyob rau hauv ib puag ncig nrog qhov kub thiab txias sib txawv, cuam tshuam rau qhov haum precision ntawm cov khoom thiab cov qauv tseem ceeb. Yog li ntawd, thaum xaiv cov khoom siv, qhov chaw siv yuav tsum tau txiav txim siab tag nrho los xyuas kom meej cov ntaub ntawv muaj kev ruaj ntseg nyob rau hauv ntau yam kev mob.
Hauv kev xaus, kev xaiv cov khoom siv rau lub tsev kawm ntawv cov rooj thiab cov rooj zaum tsis yog qhov tseem ceeb. Thaum siv high - zoo engineering plastics lossis cov hlau tsim nyog yuav ua rau cov nqi nce ntxiv, nws tuaj yeem txo qis tus nqi tsis ua haujlwm thaum siv, txuas ntxiv lub neej kev pabcuam tag nrho ntawm cov rooj zaum thiab cov rooj zaum, thiab muab cov tsev kawm ntawv thiab lwm cov neeg siv nrog kev paub txog cov neeg siv kev ntseeg siab dua thiab txo nqi tag nrho cov tswv cuab.
