Yuav ua li cas los txiav txim seb cov khoom puas tau txhaj tshuaj molded?

1. Saib xyuas qhov zoo ntawm cov khoom
Ua ntej, kev soj ntsuam cov tsos ntawm cov khoom yog txoj hauv kev los txiav txim siab ua ntej seb nws puas tau txhaj tshuaj molded. Kev txhaj tshuaj molded cov khoom feem ntau muaj qhov sib xws, cov npoo du, thiab tsis muaj qhov pom tseeb burrs lossis qhov tsis xws luag. Tsis tas li ntawd, vim yog cov pwm tsim thaum lub sij hawm txhaj tshuaj molding txheej txheem, cov khoom nto yuav nthuav tawm cov textures lossis cov qauv, uas tuaj yeem ua lub hauv paus rau kev txiav txim.
2. Tshawb xyuas cov xim thiab kev ntxhib los mos
Xim: Cov xim ntawm cov khoom txhaj tshuaj molded feem ntau yog sib xws thiab zoo ib yam, tsis muaj qhov pom tseeb xim txawv. Yog tias muaj cov xim tsis sib xws lossis cov pob nyob rau saum npoo ntawm cov khoom, nws yuav yog vim muaj impurities sib xyaw thaum lub sij hawm txhaj tshuaj molding txheej txheem los yog kev tswj kub tsis zoo. Tsis tas li ntawd, kev txhaj tshuaj molded cov khoom uas tau txais kev kho tshwj xeeb, xws li kev kho carbonization, yuav tshwm grey tsaus lossis txawm tias dub rau ntawm lawv qhov chaw, uas yog qhov tseem ceeb rau kev txiav txim siab seb cov khoom puas tau raug kho tshwj xeeb.
Kev ntxhib los mos: Kev ntxhib los mos ntawm cov khoom txhaj tshuaj molded yog du thiab muag heev, nrog rau qhov zoo tactile hnov. Cov khoom uas tsis tau txhaj tshuaj molding los yog tsis zoo txhaj tshuaj molding zoo yuav muaj ib tug ntxhib nto nrog pom tseeb graininess los yog unevenness.
3. Kev sim hardness thiab ntom
Kev kuaj Hardness: Siv lub hardness tester los ntsuas qhov hardness ntawm cov khoom yog ib qho tseem ceeb ntawm kev txiav txim seb nws puas tau txhaj tshuaj molding thiab qhov zoo ntawm kev txhaj tshuaj molding. Txhaj tshuaj molded cov khoom feem ntau muaj hardness ntau dua vim yog kev sib khi nruj ntawm cov yas hauv qhov kub thiab txias. Yog tias qhov kev ntsuam xyuas pom tau tias qhov hardness ntawm cov khoom yog qis dua li cov khoom zoo sib xws ntawm cov tshuaj molded, nws yuav qhia tau tias nws tsis tau raug txhaj tshuaj molding lossis qhov kev txhaj tshuaj molding tsis zoo.
Kev ntsuam xyuas qhov ntom ntom: Qhov ntom ntom yog ib qho khoom muaj txiaj ntsig ntawm cov khoom, thiab cov khoom siv yas sib txawv muaj qhov sib txawv. Los ntawm kev ntsuas qhov ntom ntawm cov khoom thiab muab piv nrog qhov ntom ntawm cov ntaub ntawv txhaj tshuaj molding, nws tuaj yeem txiav txim siab ua ntej seb cov khoom puas yog tsim los ntawm kev txhaj tshuaj molding txheej txheem. Nyob rau tib lub sijhawm, kev ntsuas qhov ceev kuj tuaj yeem cuam tshuam cov crystallinity thiab shrinkage degree ntawm cov khoom, yog li ntsuas nws cov kev txhaj tshuaj molding zoo.
4. Cov kev sim tshwj xeeb
Polarized daim iav nrhiav kom tau txoj kev: Rau pob tshab los yog semi pob tshab txhaj tshuaj molded khoom, polarizing iav tuaj yeem siv los xyuas lawv cov kev ntxhov siab sab hauv. Thaum lub sij hawm txhaj tshuaj molding txheej txheem, kev ntxhov siab concentration yuav tshwm sim hauv cov khoom vim qhov ntws thiab txias shrinkage ntawm cov yas. Los ntawm kev soj ntsuam nrog daim iav polarizing, cov xim hloov pauv hauv thaj chaw muaj kev ntxhov siab tuaj yeem pom meej, yog li txiav txim siab qhov kev txhaj tshuaj zoo thiab qhov zoo ntawm cov khoom.
combustion test method: Kev ntsuas kev sib txuas yog ib txoj hauv kev txiav txim siab cov khoom siv thiab kev txhaj tshuaj zoo ntawm cov khoom yas los ntawm kev soj ntsuam lawv cov kev ua tau zoo thaum lub sij hawm combustion. Cov khoom siv yas sib txawv yuav tsim cov yam ntxwv sib txawv xws li nplaim xim, tsw ntxhiab, thiab kev sib kis ceev thaum hlawv. Los ntawm kev sib piv cov yam ntxwv no, nws tuaj yeem txiav txim siab ua ntej seb cov khoom puas yog tsim los ntawm kev txhaj tshuaj molding txheej txheem thiab hom khoom siv yas siv.
5. Kev ntsuas qhov loj thiab qhov hnyav
Kev ntsuas qhov ntev: Siv cov cuab yeej ntsuas kom meej los ntsuas qhov ntev ntawm cov khoom thiab sib piv nrog cov qauv kos duab lossis qauv qhov ntev. Txhaj tshuaj molded khoom feem ntau muaj siab precision thiab sib xws ntawm qhov loj me. Yog hais tias cov khoom loj sib txawv loj los yog muaj qhov pom tseeb deformation, nws yuav qhia tau tias nws tsis tau txhaj tshuaj molding lossis txhaj tshuaj molding tsis zoo.
Kev ntsuas qhov hnyav: Los ntawm kev ntsuas qhov hnyav ntawm cov khoom thiab suav nws raws li qhov tsis xws li ntim thiab qhov ntom ntom, cov khoom siv thiab kev txhaj tshuaj zoo ntawm cov khoom tuaj yeem txiav txim siab ua ntej. Feem ntau hais lus, txhaj tshuaj molded cov khoom muaj qee qhov kev ruaj ntseg thiab sib xws hauv qhov hnyav. Yog tias qhov sib txawv ntawm qhov hnyav ntawm cov khoom loj lossis tsis ua raws li qhov xav tau, nws yuav qhia tau tias muaj teeb meem nrog nws cov khoom siv lossis cov txheej txheem txhaj tshuaj molding.
6. Ua tib zoo xav txog lwm yam
Ntxiv nrog rau cov txheej txheem saum toj no, lwm yam yuav tsum tau ua kom tiav thaum txiav txim siab seb cov khoom puas tau txhaj tshuaj molded. Piv txwv li, cov txheej txheem tsim khoom, hom thiab zoo ntawm cov khoom siv raw siv, qib siab ntawm cov khoom siv ntau lawm, thiab qhov chaw tsim khoom txhua tus muaj kev cuam tshuam rau kev txhaj tshuaj molding zoo ntawm cov khoom. Yog li ntawd, thaum txiav txim siab, nws yog ib qho tsim nyog yuav tsum muaj kev nkag siab zoo ntawm cov ntaub ntawv tseem ceeb thiab kev paub txog keeb kwm yav dhau ntawm cov khoom.
