Hloov ib qho extruder ntsia hlau thaum ntsuas hnav lossis kev puas tsuaj tiv thaiv tus qauv tsim los ntawm kev ua nws txoj haujlwm. Hloov kho nws thaum lub ntsia hlau yog lub suab nrov-los yog yuav tsum tau hloov pauv-tab sis cov ntaub ntawv hloov pauv hauv cov khoom siv, cov khoom lag luam zoo lossis cov khoom tsim tawm xav tau sib txawv melting, sib tov, venting los yog hnav-tiv taus lub tswv yim. Ua ntej ob qho kev txiav txim siab, xyuas lub thoob thiab lwm qhov ntawm cov kab: lub hau ntswj tshiab tsis tuaj yeem kho cov khoom noj tsis zoo, cov khoom ntub dej los yog txwv tsis pub tuag.

Qhov zoo tshaj plaws extruder ntsia hlau yog ib qho uas daws koj txoj kab txoj haujlwm txwv: pub, yaj, sib tov, tso pa tawm, los yog siv los tiv thaiv kev tuag. Pib nrog cov resin thiab pub daim ntawv, tom qab ntawd kuaj xyuas qhov tseeb ntawm lub fwj dej ua ntej xaiv cov pa, thaiv, sib tov, lossis vented tsim. Ib lub ntsia hlau uas txhim kho ib txoj haujlwm tuaj yeem ua rau lwm qhov tsis zoo, yog li lub tshuab, chim, tuag, thiab kev lees paub yuav tsum tau teev ua ke.

Yog hais tias koj cov resin los yog compound tuaj txog npaj rau extrusion thiab lub ntsiab teeb meem yog ruaj khov melting thiab siab tus me nyuam, pib nrog ib tug kom zoo teev ib tug ntsia hlau. Yog hais tias lub extruder yuav tsum sib tov cov khoom xyaw, haum rau cov hmoov nyuaj los yog muab tub lim noj, los yog txhawb nqa kev koom tes ntau venting, soj ntsuam qhov sib npaug sib npaug ntxaib-ntsia hlau architecture; rau PVC yeeb nkab lossis profiles, suav nrog conical twin-ntsia hlau xaiv qhov twg nws cov txheej txheem haum yog tsim nyog.

Tsis txhob yuam kom pob tshab granulation ib leeg ntsia hlau los ntawm daim duab ntawm cov specks dub ib leeg. Sau thaum qhov tsis xws luag tshwm sim, tshuaj xyuas cov khoom noj thiab cov dej ntws qis, sib piv cov kev ua haujlwm, tom qab ntawd ntxuav thiab ntsuas cov ntsia hlau thiab lub thoob raws li cov nroj tsuag tau pom zoo cov txheej txheem tu. Nanhaiya lub pob tshab granulation ib leeg ntsia hlau qhia txog kev hloov pauv, tswj cov yaj thiab ua kom tiav. Cov yam ntxwv no tseem ceeb thaum tam sim no geometry lossis nto yog qhov tseeb ntawm cov khoom khaws cia lossis degraded.

Qhia meej PS foaming ib qho ntsia hlau los ntawm kev hais txog daim ntawv pub khoom noj thiab daim ntawv qhia, dab tsi yuav tsum tau yaj thiab sib xyaw ua ntej roj nthuav dav, lub thoob uas twb muaj lawm thiab tuag cuam tshuam, thiab cov khoom ua npuas dej ntsuas qhov kev lees paub. Nanhaiya's PS foaming ib leeg ntsia hlau siv lub tswv yim tsim L / D ntev dua, ntu pub khoom siv los txav PS thiab nucleating cov neeg ua haujlwm, thiab xaiv Maddock-hom lossis tus pin sib xyaw seem. Tsis muaj ib qho ntawm cov yam ntxwv no hloov pauv rau koj cov ntaub ntawv kab tiag tiag.

Yuav kom cov granulation parallel ntxaib ntsia hlau, qhia meej cov khoom noj khoom haus thiab lub hom phiaj pellet, lub tshuab kev sib hloov thiab cov ntsia hlau-pair geometry, thaj chaw ua haujlwm, lub thoob haum thiab yuav tsum tau hnav kev tsim kho. Nanhaiya's granulation khoom nplooj ntawv teev 38CrMoAlA, kev kho cua sov, nitriding, chrome thiab bimetal siv qhov tseem ceeb, nrog rau cov khoom siv kev cai thiab kev xaiv rau cov nkauj xwb thiab siv cov thermoplastics. Xaiv ib qho kev tsim kho rau thaj chaw txiav txim es tsis yog kho txhua tus nqi saum npoo raws li qhov tshwj xeeb ntawm txhua qhov ntsia hlau. Qhov kev txiav txim tiav thaum nws tseem txheeb xyuas cov ntaub ntawv tshuaj xyuas thiab kev sim ntawm daim ntawv qhia ntau lawm. Kev khiav luv luv nrog ib qho yooj yim resin tsis ua pov thawj tias lub hau ntswj yuav ua rau cov pellet xav tau los ntawm cov khoom siv rov ua dua tshiab.
