Plastic processing forced air ncus- siv rau preheating extruder chim, ziab resin pellets, thiab annealing yas qhov chaw- ntsib teeb meem xws li qeeb cua sov hloov, siab siv zog, thiab nquag nquag burnout. Cov teeb meem no tshwm sim vim raug yuam cua muaj thermal conductivity tsawg, thiab ib txwm du - cov cua sov saum npoo tawm tsam kom hloov cov cua sov kom zoo. Hauv kev xyaum, finned cartridge heaters [cartridge heater] daws cov teeb meem no los ntawm kev ua kom sov siab tshaj qhov chaw hloov chaw thiab kev sib cuam tshuam ntawm huab cua, ua rau lawv qhov kev xaiv zoo tshaj plaws rau kev ua cov yas yuam cua tshuab.
Finned cartridge heaters [cartridge heater] feature aluminium los yog stainless hlau fins (5-10 fins ib nti) uas nce thaj tsam ntawm 300% -500% piv rau cov casings du, drastic txhim kho convection tshav kub hloov nyob rau hauv yuam cua. Raws li kev paub dhau los, qhov kev tsim no txo cov cua sov- lub sijhawm nce los ntawm 40% thiab txiav lub zog siv los ntawm 25% hauv cov tshuab ziab khaub ncaws yas, qhov xav tau huab cua sib npaug 120℃kom tshem tawm cov dej noo los ntawm cov khoom siv hygroscopic xws li PET lossis nylon. Cov fins kuj tseem tiv thaiv cov cua sov hauv cheeb tsam los ntawm kev faib cov cua sov sib npaug, txuas lub neej mus rau 6,{11}} teev hauv kev ua haujlwm tas mus li- ntev dua li cov cua sov uas ua kom qis sai sai hauv kev quab yuam huab cua.
Cov khoom siv thiab cov fin yog tsim raws li kev xav tau ntawm kev ua cov yas. Rau kev ziab kom qhuav (80℃-150 degree), 304 stainless hlau fins nrog corrosion-txheej txheej tiv thaiv plua plav buildup thiab xyuas kom yooj yim tu. Rau extruder chim preheating (200℃-350 degree), Inconel fins tswj kev ncaj ncees ntawm cov kub kub, tsis txhob warping uas thaiv airflow. Power density ranges from 10–25 W/cm² for resin drying (lower density to prevent resin degradation) to 25–35 W/cm² for barrel preheating (higher density for rapid heat transfer). Hauv kev xyaum, kev sib koom ua ke finned cartridge rhaub nrog qhov sib txawv -blowers ceev ntxiv ua kom zoo dua los ntawm kev kho cua kom haum rau qhov xav tau cua sov, tsis txhob siv hluav taws xob pov tseg los ntawm kev ua haujlwm siab tas li -.
Kev teeb tsa hauv qhov cub ua cov yas yuav tsum tau ua tib zoo saib xyuas qhov fin orientation thiab qhov sib nrug. Fins yuav tsum ua raws li cov kev taw qhia ntawm airflow kom txo tau qhov tsis kam, thiab cov cua sov yuav tsum tau sib nrug 20-30 cm sib nrug los tiv thaiv fin sib tshooj thiab ua kom cov huab cua sib txawv. Cov hlau lead yuav tsum tau tawm sab nraum lub qhov cub rwb thaiv tsev thiab kaw nrog cua sov- silicone tiv thaiv tiv thaiv 300℃+ huab cua xau. Kev saib xyuas tsis tu ncua-nrog rau kev tu cov fin nrog cov cua compressed txhua 4 lub lis piam- tiv thaiv cov plua plav av uas txo cov kev hloov hluav taws xob los ntawm 15%–20%. Ntxiv cov thermal fuses rau txhua lub rhaub hluav taws xob kuj tseem tiv thaiv kev puas tsuaj yog tias tsis muaj cua nkag, tiv thaiv cov khoom siv hluav taws xob kim.
Hauv cov ntsiab lus, finned cartridge heaters [cartridge heater] yog cov kev daws teeb meem zoo tshaj plaws rau kev yuam cua cua sov hauv cov yas ua cov ncu, muab cov cua kub hloov sai dua, kev siv hluav taws xob qis dua, thiab lub neej ntev dua. Txhawm rau kom tsis txhob ua kom qhuav qeeb thiab nquag hloov cov khoom siv, xaiv finned heaters nrog cov khoom sib txuam nrog cov txheej txheem kub, ua kom zoo dua fin tsim rau airflow, thiab ua raws li kev teeb tsa thiab kev saib xyuas kom zoo. Cov txheej txheem yas sib txawv (txhaj tshuaj molding, extrusion, tshuab moulding), hom resin (hygroscopic vs. non- hygroscopic), thiab qhov cub qhov cub yuav tsum tau customized fin ntom, lub zog ceev, thiab layout. Kev tsim qauv tsim ua kom muaj qhov zoo sib xws, lub sijhawm luv luv, thiab txo cov nqi ua haujlwm rau cov tuam txhab yas.
