Cov Khoom Siv Khoom Zoo
1.Thermal conductivity ntawm cov khoom: Qhov no yog qhov tseem ceeb tshaj qhov cuam tshuam. Siv cov roj hmab los yog cov hmoov yas ua piv txwv, lawv cov thermal conductivity feem ntau qis heev, ua rau tsis zoo rau kev hloov pauv cua sov. Thaum tshav kub kub tawm tsam kom hloov pauv sai ntawm lub thoob phab ntsa rau hauv cov khoom siv sab hauv, yooj yim ua rau qhov kub thiab txias sib txawv ntawm cov khoom siv sab nrauv thiab sab hauv.
2.Material morphology thiab uniformity: Cov duab, particle loj, thiab sib xyaw uniformity ntawm cov khoom, tag nrho cov cuam tshuam nws kev sib cuag thermal kuj nrog lub thoob thiab ntsia hlau nto, yog li cuam tshuam rau tshav kub exchanger efficiency.
Cov khoom siv thiab cov xwm txheej xwm txheej
1.Kev hnav ntawm cov ntsia hlau thiab lub thoob: Tom qab siv sijhawm ntev hauv cov khoom siv thib ob, hnav tuaj yeem tshwm sim ntawm cov ntsia hlau thiab lub thoob, ua rau muaj kev tshem tawm ntau ntxiv. Qhov no tsis yog tsuas yog ua rau cov dej xau thiab txo cov zis tab sis kuj tsim ib txheej ntawm cov khoom siv insulating ntawm cov ntsia hlau thiab cov phab ntsa sab hauv (tshwj xeeb tshaj yog cov khoom siv tsis zoo thermal conductivity). Qhov no hnyav heev impairs tshav kub hloov ntawm lub thoob mus rau cov khoom.
2.Heat Exchange System Performance: Kev tsim ntawm lub extruder tus kheej cua sov / cua txias system yog qhov tseem ceeb. Piv txwv li, kev tshawb fawb qhia tau hais tias kev sib koom ua haujlwm siab - cov khoom siv hluav taws xob hloov pauv tau zoo xws li hloov pauv tau - txoj kab uas hla pulsating cua sov kav hauv extruder lub tshuab hluav taws xob tuaj yeem txo lub sij hawm pib cua txias los ntawm ib qho - thib peb piv rau cov kav dej kub ib txwm muaj thaum ua tiav qhov sib txawv ntawm qhov kub thiab txias. Kev laus lossis kev ua haujlwm tsis zoo ntawm cov cua sov coils, cov kav dej txias, ntsuas kub tswj, thiab lwm yam khoom siv hauv cov khoom siv yuav cuam tshuam ncaj qha rau kev hloov hluav taws xob.
3.Screw Configuration thiab Tsim: Cov ntsia hlau qhov tob, lub suab, thiab kev suav nrog cov khoom sib xyaw tshwj xeeb txiav txim siab cov khoom ntws thiab lub sijhawm nyob hauv lub thoob. Lub qhov dej- tsim cov ntsia hlau txuas ntxiv txuas ntxiv cov khoom siv nyob rau hauv kev sib cuag nrog lub thoob phab ntsa los ntawm kev quab yuam convection thiab shear action, yog li txhim kho cov cua sov. Yog hais tias tus ntsia hlau configuration ntawm cov cuab yeej siv yog incompatible nrog cov khoom siv tam sim no, cov khoom siv hluav taws xob hloov hluav taws xob yuav raug cuam tshuam loj heev.
4.Barrel Structure: Tus tsim ntawm lub extruder chim (xws li seb nws yog slotted thiab faib cov cua sov thiab cua txias zones) kuj cuam tshuam rau txoj kev thiab efficiency ntawm tshav kub hloov lwm lub tsev.
Txheej txheem ua haujlwm yam
1. Screw Speed: Kev sib hloov ceev ncaj qha cuam tshuam cov khoom shear tshav kub thiab lub sijhawm nyob. Kev ua kom nrawm ntxiv txhim kho shear-vim cua sov tab sis tib lub sijhawm txo cov khoom siv nyob hauv lub thoob, xav tau qhov sib npaug zoo ntawm cov khoom no.
2. Kev Kub Ntxhov thiab Kev Tswj Xyuas: Kub qhov chaw nkhaus rau txhua ntu ntu, nrog rau qhov kub thiab txias thiab cov lus teb ceev, cuam tshuam ncaj qha rau kev tsav tsheb thiab kev sib hloov ntawm cov cua sov.
3. Rov qab siab thiab pub tus nqi: Tsim nyog rov qab siab nce cov khoom ntom ntom thiab lub sijhawm nyob, txhim kho cov cua sov hloov. Tus nqi noj khoom noj ruaj khov yog qhov tseem ceeb rau kev tswj xyuas qhov sib npaug ntawm cov cua sov thoob plaws hauv lub cev.
