Qhia kom meej ib tug granulation ib leeg ntsia hlau nyob rau hauv qhov kev txiav txim no: feedstock, yuav tsum tau yaj npaj, venting load, sib tov lub luag hauj lwm, pom kuj thiab pelletizing txoj kev. Qhia seb cov khoom noj puas yog huv pellet, hmoov, agglomerate, ntxuav flake los yog ib tug sib txawv recycled kwj. Muab qib resin, MFR kuaj mob, noo noo, paug, muab tub lim, lub hom phiaj tso zis, lub cev muaj zog, rpm, lub tshuab nqus tsev thiab cov tsos mob tam sim no. Cov ntsia hlau tuaj yeem raug tsim nyob ib ncig ntawm lub qhov rais ntawm cov khoom siv tiag tiag es tsis txhob siv lub taub nominal.

Xaiv ib zaj duab xis- tshuab tshuab hauv qhov kev txiav txim no: resin thiab formulation, tiav zaj duab xis thiab txheej txheej, kab lub luag hauj lwm, ces ntsia hlau geometry thiab nto system. Nug kom paub meej cov qib resin thiab yaj ntws kuaj mob, tsis yog "LDPE," "LLDPE" lossis "HDPE." Sau cov khoom sib xyaw, cov khoom siv ntxiv, cov ntsiab lus rov ua dua tshiab, tso zis, ntsia hlau nrawm, lub cev muaj zog, tuag, zaj duab xis dav thiab thickness ntau yam. Tsuas yog tom qab ntawd txiav txim siab txoj kab uas hla, L / D, pub qhov tob, melting profile, metering seem thiab seb ib qho kev thaiv lossis qhov sib xyaw yog qhov ncaj ncees.

Ntsuas hnav raws li qhov chaw raws li khub, tsis yog ib txoj kab uas hla. Kos axial chaw nres tsheb los ntawm kev pub, compression thiab metering aav. Ntawm txhua qhov chaw nres tsheb, sau cov ntsia hlau ya dav hlau sab nraud thiab lub thoob hauv txoj kab uas hla hauv ntau cov lus qhia angular. Tom qab ntawd xam cov diametral thiab radial clearance cais. Sib piv daim duab qhia chaw nrog daim duab pom zoo thawj zaug lossis ib qho kev pom zoo tsim qauv siv. Yog tias koj tsuas muaj qhov hnav, sau cov txiaj ntsig raws li cov ntaub ntawv mob. Tsis txhob nthuav tawm lawv raws li qhov loj me.

Hloov cov ntsia hlau tsuas yog thaum ntsuas lub thoob bore, roundness, deg mob thiab kev sib raug zoo nyob twj ywm haum rau lub tswv yim tshiab ntsia hlau. Hloov ob qho tib si thaum lub thoob loj, oval, hauv zos ntxuav tawm, tau qhab nia lossis corroded txaus tias cov ntsia hlau tshiab tseem yuav khiav nrog ntau dhau lossis tsis sib xws. Yog tias koj tsis muaj qhov ntsuas ntsuas, tsis txhob twv. Peb lub Hoobkas txoj haujlwm yog qhov yooj yim: cov lus hais ntawm cov ntsia hlau nkaus xwb yuav tsum tsis txhob raug kho raws li kev pom zoo ua tiav kom txog rau thaum kuaj xyuas lub thoob.

Xaiv cov ntsia hlau zoo ib yam rau qhov ruaj khov, zoo li cov pellet pub thiab cov zis nruab nrab thaum ua haujlwm yooj yim yog qhov tseem ceeb. Xaiv ib qho kev thaiv qhov ntsia hlau thaum txoj kab xav tau ntau dua melting thiab ruaj khov tso zis ntawm tus nqi siab dua, tshwj xeeb tshaj yog rau PE thiab PP. Xaiv cov ntsia hlau sib tov thaum yaj-kub tsis sib xws, xim faib los yog cov khoom ntxiv dispersion yog qhov teeb meem loj. Barrier thiab kev sib xyaw ua haujlwm tsis yog kev sib koom ua ke. Nanhaiya's aluminium-yas vaj huam sib luag ib leeg ntsia hlau, piv txwv li, siv cov khoom sib xyaw ua ke los txhawb kev yaj, yaj-kub sib xws thiab faib cov xim thiab cov nplaim hluav taws.

Ib qho ntsia hlau extruder surges thaum cov khoom ntws los ntawm txoj kab nres tsis tu ncua. Cov peev txheej feem ntau suav nrog kev pub mis tsis sib xws, kev hloov pauv ceev ceev, qhov ntsuas kub tsis ruaj khov, tsis tiav lossis tsis ruaj khov, qhov hloov pauv lossis kev txwv tsis pub tuag, ntsia hlau-thiab-ntim hnav, thiab kev hloov pauv ceev hauv qab. Cov ntaub ntawv yaj lub siab, lub cev muaj zog tam sim no, ntsia hlau ceev, cheeb tsam kub, pub tus nqi thiab downstream ceev ntawm tib lub sijhawm ua ntej hloov chaw. Yog tias lub siab thiab cov zis txav mus ua ke, tshawb xyuas cov extruder thiab ntws txoj kev. Yog hais tias tus extruder tiam sis nyob ruaj khov thaum cov khoom hloov, pib nrog cov tuag, txias, nqus tsev vacuum, tshem tawm los yog winder.
