Siab -Tub kub tsis kam ntawm PET khob
Raws li cov khoom siv yas, qhov siab -kub tsis kam ntawm PET khob yog ib qho teeb meem ntawm kev txhawj xeeb rau cov neeg siv khoom. Feem ntau, lub melting point ntawm PET yas yog nyob ib ncig ntawm 250 degree, txhais tau tias nws tuaj yeem tiv taus luv luv rau qhov kub thiab txias. Txawm li cas los xij, hauv kev siv tiag tiag, qhov kub tsis kam ntawm PET khob yog cuam tshuam los ntawm ntau yam, xws li kev tsim khoom thiab cov khoom siv ntxiv.
Raws li cov ntaub ntawv tseem ceeb, cov khob PET ua raws li feem ntau tuaj yeem tiv taus qhov kub ntawm li 65 txog 80 degree. Hauv qhov no, PET khob tuav lawv cov duab thiab kev ua haujlwm ruaj khov, ua rau lawv haum rau tuav cov dej kub xws li tshuaj yej thiab kas fes. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev sib cuag nrog cov kua kub ntev los yog raug rau cov khoom siv hluav taws xob tuaj yeem ua rau PET khob deform, soften, los yog tso tawm cov khoom ua rau tib neeg noj qab haus huv. Yog li ntawd, ib tug yuav tsum tsis txhob tuav cov dej kub hauv khob PET rau lub sij hawm ntev thiab -tseem ceeb heev - tsis txhob muab tso rau hauv cov khoom siv cua sov xws li microwave ncu.
Tsawg-Qhov Kub Ua Haujlwm ntawm PET khob
Ntxiv nrog rau kev tiv thaiv tshav kub, lub peev xwm ntawm PET khob kom tiv taus qhov kub thiab txias kuj yog ib qho kev txhawj xeeb tseem ceeb rau cov neeg siv khoom. Feem ntau, cov khoom siv PET tswj kev ua haujlwm ruaj khov ntawm qhov kub thiab txias. Cov ntaub ntawv ntsuam xyuas qhia tau tias cov khob PET tuaj yeem siv rau hauv qhov qis - qhov kub thiab txias ntawm -20℃txog -70℃yam tsis muaj kev hloov pauv tseem ceeb hauv kev ua haujlwm.
Thaum lub zog thiab lub zog ntawm PET khob tuaj yeem txo qis me ntsis hauv qhov chaw qis - qhov kub thiab txias, lawv feem ntau nyob twj ywm thiab ua haujlwm tau zoo. Yog li ntawd, PET khob yog ib qho kev xaiv zoo rau kev siv thaum lub caij ntuj no txias los yog nyob rau hauv cov xwm txheej xav tau tub yees. Txawm li cas los xij, ceev faj: ceev ceev lub khob PET los ntawm qhov qis - qhov kub thiab txias ib puag ncig mus rau qhov siab - qhov kub thiab txias tuaj yeem ua rau lub siab tsis sib haum ntawm sab hauv thiab sab nraud ntawm lub khob, uas yuav ua rau tawg. Yog li ntawd, xws li kub hloov pauv yuav tsum tau zam thaum siv.
Kev ceev faj rau kev siv PET khob
Tsis txhob tuav cov kua dej kub rau lub sijhawm ntev: Txawm hais tias lub khob PET muaj qee qhov kev tiv thaiv tshav kub, kev sib cuag nrog cov kua kub ntev ntev tuaj yeem ua rau deformation, softening, los yog tso tawm cov khoom tsis zoo. Cov neeg siv yuav tsum tau sim kom tsis txhob muaj cov xwm txheej zoo li no.
Tsis txhob tso cua sov hauv cov khoom siv xws li microwave ncu: Vim tias cov khoom siv PET tsis tsim los tiv taus siab -kub cua sov, PET khob yuav tsum tsis txhob muab tso rau hauv qhov cub microwave lossis lwm yam khoom siv cua sov. Ua li no tuaj yeem ua rau lub khob yaj lossis deform, lossis ua rau muaj kev nyab xeeb xws li hluav taws kub. Zam kev hloov pauv kub ceev: Thaum siv cov khob PET, tsis txhob txav lawv sai sai ntawm qhov qis - qhov kub thiab txias mus rau qhov kub siab - qhov kub, vim qhov ua rau qhov tsis sib xws ntawm sab hauv thiab sab nraud tuaj yeem ua rau lawv tawg.
Hloov tsis tu ncua: Txhawm rau kom muaj kev nyab xeeb thiab huv si, nws raug nquahu kom hloov cov khob PET ib ntus. Koj yuav tsum hloov lub khob tam sim yog tias muaj cov tsos mob ntawm hnav, khawb, lossis tsis muaj xim tshwm sim.
Hauv cov ntsiab lus, thaum lub khob PET muaj qee qhov kev tiv thaiv rau qhov kub thiab txias, kev siv kom zoo yuav tsum zam kom tsis txhob sib cuag nrog cov kua kub ntev, tsis txhob tso cua sov rau hauv cov khoom siv, thiab tiv thaiv kom tsis txhob raug kub kub hloov pauv. Tsuas yog los ntawm kev siv thiab kev saib xyuas kom raug koj tuaj yeem ua kom muaj kev nyab xeeb thiab txuas ntxiv lub neej ntawm lub khob.
