Yuav ua li cas los daws qhov kev laus phenomenon ntawm tuj hnab?
Lub hnab ntim khoom yog ib qho ntawm cov khoom ntim yooj yim uas feem ntau siv hauv kev tsim khoom thiab ua lub luag haujlwm tseem ceeb hauv kev thauj khoom. Yog li, peb yuav ua li cas nrog kev laus ntawm cov hnab ntim khoom?
Ua ntej tshaj plaws, nws yog ib qho tsim nyog yuav tsum nkag siab txog cov neeg siv khoom tiv thaiv kev laus xav tau rau lub hnab ntim ton, tsim cov phiaj xwm kev ua haujlwm raws li tus neeg siv khoom xav tau, thiab ntxiv cov tshuaj tiv thaiv kev laus raws li qee qhov kev faib ua feem.
Qhov thib ob, tsim cov qauv tsim khoom. Vim muaj qhov tshwm sim kev laus ntawm cov khoom siv rov ua dua tshiab, cov khoom siv kho tshuab ntawm cov ntaub ntawv raug txo, thiab lub neej kev pab cuam ntawm lub hnab ntim tau luv luv. Yog li ntawd, cov ntaub ntawv raw ntawm lub hnab ntim yuav tsum tau ua los ntawm cov ntaub ntawv tshiab.
Txawm hais tias nws yog ib lub hnab ntim khoom thib ob, lub hnab ntim tsis tu ncua kuj tseem muaj cov ntaub hauv qab, cov hlua khi, cov khoom siv lub qhov ncauj, xov xaws, thiab lwm yam. Cov khoom no yuav tsum ua kom tau raws li qhov xav tau los tiv thaiv kev laus. Thaum muaj teeb meem tshwm sim, nws yuav cuam tshuam rau kev siv.
Dab tsi yuav tsum tau ceev faj thaum sib xyaw cov hnab ntim khoom?
Hauv kev tsim cov thawv ntim khoom, cov khoom siv raw yuav tsum sib xyaw thaum lub sijhawm tsim khoom. Thaum sib tov, tsis tsuas yog qhov sib piv tseem ceeb heev, tab sis ntau lwm yam yuav tsum tau them sai sai rau. Ua li no, cov hnab ntim khoom zoo tuaj yeem tsim tau.
Thaum sib tov cov khoom tshiab thiab qub, tshwj xeeb yuav tsum tau them nyiaj rau kev sib xyaw ua ke. Nyob rau tib lub sijhawm, cov khoom siv raw nrog cov ntsuas zoo sib xws yuav tsum raug xaiv rau kev sib xyaw ntawm cov thawv ntim khoom. Yog hais tias lub melting Performance index ntawm raw cov ntaub ntawv sib txawv heev, lub melting kub yuav txawv heev. Thaum lub sij hawm plasticizing thiab extrusion txheej txheem, lub plasticization tsis tuaj yeem sib xws tib lub sijhawm, uas yuav cuam tshuam rau cov duab kos thiab ua rau qhov zoo ntawm cov xov paj tiaj tus.
Nyob rau tib lub sijhawm, tus nqi tawg ntawm cov hlau thiab cov khoom seem yog siab, thiab kev tsim khoom txawm tias tsis yooj yim sua. Thaum lub sij hawm sib tov ntawm cov thawv ntim khoom, lub sij hawm kom qhuav thiab kub ntawm cov ntaub ntawv raw yuav tsum tau them sai sai rau.
