Hauv kev tsim khoom, tshwj xeeb tshaj yog kev tsim cov hlau thiab lwm yam khoom siv hlau, cov txheej txheem crystallization yog ib kauj ruam tseem ceeb hauv kev ua kom zoo thiab kev ncaj ncees ntawm cov khoom kawg. Ib qho tseem ceeb ntawm txoj kev yog qhovtooj liab pwm tube, uas plays lub luag haujlwm tseem ceeb hauv kev txhawb nqa kev sib koom ua ke ntawm cov hlau molten rau hauv ib daim ntawv.

Suavcrystallizer tooj liab tubes,kuj hu ua crystallizer tooj liab raj thiabTp2 cev, yog dav lees paub rau lawv zoo heev thermal conductivity, siab kub kuj thiab zoo heev corrosion kuj. Cov khoom no ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tsim cov pwm tooj liab siv hauv cov txheej txheem crystallization.

Lub luag hauj lwm ntawm cov pwm tooj liab raj hauv cov txheej txheem crystallization yog hloov cov cua sov los ntawm cov hlau khov rau hauv cov dej txias, kom ntseeg tau tias cov hlau ua kom zoo thiab tsim cov qauv zoo ib yam thiab tsis muaj qhov tsis xws luag. Qhov no yog ua tiav los ntawm cov qauv tsim ntawm lub raj pwm tooj liab, uas tso cai rau kev hloov pauv kom zoo thaum tiv taus qhov kub thiab txias ntawm cov txheej txheem.

Tsis tas li ntawd, lub siab thermal conductivity ntawm tooj liab pwm raj ua kom lub cev txias ntawm cov hlau molten, uas yog qhov tseem ceeb rau kev tsim cov hlau zoo thiab lwm yam khoom siv hlau. Lub peev xwm ntawm tooj liab pwm tubing kom muaj kev ruaj khov thiab tswj qhov kub thiab txias ib puag ncig thaum lub sij hawm crystallization txheej txheem yog qhov tseem ceeb rau kev tiv thaiv kev tsim ntawm cov teeb meem sab hauv xws li tawg thiab voids hauv cov khoom kawg.

Ntxiv rau nws cov khoom siv thermal, qhov kev tiv thaiv corrosion ntawm tooj liab crystallizer hlab hauv qhov hnyav ua haujlwm ntawm cov txheej txheem crystallization yog qhov zoo dua. Kev raug rau cov hlau molten, kub kub, thiab dej txias tuaj yeem ua rau cov pwm pwm degrade thaum lub sijhawm. Txawm li cas los xij, qhov zoo tshaj plaws corrosion kuj ntawm Tp2 tooj liab pwm raj ua kom lub sij hawm ntev thiab kev ntseeg siab, txo kev txij nkawm thiab hloov cov nqi.

Raws li qhov kev thov rau cov hlau zoo thiab lwm yam khoom siv hlau txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm cov pwm pwm hauv cov txheej txheem crystallization tsis tuaj yeem overstated. Siv cov khoom zoo Suav pwm tooj liab raj tsis tsuas yog ua kom cov khoom tsis raug thiab cov khoom siv hlau ua tau zoo, tab sis kuj pab txhim kho tag nrho cov txiaj ntsig thiab kev tsim khoom ntawm cov txheej txheem tsim khoom.

Hauv cov ntsiab lus, lub luag haujlwm ntawm cov hlau pwm hauv cov txheej txheem crystallization yog qhov tseem ceeb rau kev tsim cov hlau zoo thiab lwm yam khoom siv hlau. Tp2 tooj liab pwm tube zoo heev thermal conductivity, siab kub tsis kam thiab corrosion kuj ua rau nws thawj xaiv rau manufacturers nrhiav kom tau raws li zoo raws li, txhim khu kev qha tau. Raws li qhov kev thov rau cov khoom siv hlau zoo txuas ntxiv mus ntxiv, qhov tseem ceeb ntawm kev siv cov hlau pwm zoo tuaj yeem tsis tuaj yeem kwv yees.
