Xov xwm kev lag luam

Txhawm rau yuav WPC extrusion pwm, xa qhov kawg ntu ntu nrog kev ua siab ntev, ua tiav cov qauv polymer thiab ntoo-filler, cov txheej txheem npaj cov khoom, lub hom phiaj tso tawm thiab kab nrawm, extruder interface, cov txheej txheem cua txias thiab cov khoom tiav tiav. Kos qhov chaw pom, phab ntsa tseem ceeb, sab hauv tav, kab noj hniav, radii thiab tej embossing lossis sanding nyiaj pub dawb rau ntawm daim duab. Tsis txhob txais cov cuab yeej los ntawm daim ntawv qhia txog qhov ntev ib leeg. Khiav cov qauv pom zoo los ntawm txoj kab npaj, cia qhov profile txias, tom qab ntawd ntsuas qhov ntev, phab ntsa thiab tav thickness, ncaj, twist, qhov chaw thiab qhov loj ntawm ib qhov ntev. Kev ntsuam xyuas cov khoom lag luam tseem yog lub luag haujlwm ntawm cov khoom lag luam tiav.

Yuav kom cov yeeb nkab extrusion tuag lub taub hau, xa tus neeg muag khoom tsib cov ntaub ntawv sib tw: cov khoom siv thiab kev tsim; cov yeeb nkab txheem, txoj kab uas hla thiab phab ntsa; tso zis thiab kab ceev; lub extruder flange thiab yaj-inlet interface; thiab lub downstream calibrator, lub tshuab nqus tsev, txias thiab tshem tawm kev npaj. Ib qho kev thov uas tsuas yog "PVC yeeb nkab, 110 mm" tsis tau npaj rau engineering. Qhov kev cog lus tseem ceeb tshaj plaws yog qhov kev lees paub. Lub npe ntawm cov khoom siv tiag tiag, cov yeeb nkab loj, cov zis ruaj khov, kab nrawm, cua sov thiab sensor teeb, tso cai rau phab ntsa variation, sab nraud txoj kab uas hla, ovality, deg mob thiab yuav tsum tau kuaj cov khoom. Lub taub hau tuag zoo li kub yaj, tab sis nws tsis tuaj yeem lav qhov kawg ntawm cov yeeb nkab txias.

Ntsuas parallel twin ntsia hlau thiab chim hnav raws li qhov sib txuam. Sau ob lub screws ntawm lub npe axial chaw nres tsheb, ob lub lobes ntawm daim duab-yim bore nyob rau hauv cov lus qhia, ntsia hlau-rau-screw clearance, nruab nrab nrug, phasing thiab axial haum. Sib piv daim ntawv qhia nrog daim duab pom zoo. Cov tsos mob tuaj yeem ua rau muaj kev tshuaj xyuas, tab sis kev ntsuas txiav txim siab seb puas yuav hloov cov ntsia hlau, lub thoob lossis cov txheej txheem tiav.

Rau high-filled PVC, qhia kom meej daim ntawv qhia ua tiav nyob rau hauv phr, pub txoj kev, cov khoom kawg, yuav tsum tau tso zis, ntsia hlau rotation, nruab nrab nrug, kev twb kev txuas qhov ntev thiab hnav daim ntawv qhia ntawm ob lub screws thiab chim bores. Xaiv nitriding, chrome plating los yog txheej bimetallic tiv thaiv lub luag haujlwm tiag tiag. Pom zoo rau kev kos duab thiab tshuaj xyuas txoj kev ua ntej tus nqi dhau los ua qhov kev txiav txim siab.

Yog tias txhaj tshuaj molding ntsia hlau rov qab siv sijhawm ntev heev, thawj zaug paub meej tias nws ncua lub voj voog. Tom qab ntawd xyuas cov khoom noj txuas ntxiv, qhov tseeb ntsia hlau ceev, rov qab siab thiab qhov kub thiab txias tiv thaiv kev ua haujlwm ruaj khov. Tshawb xyuas geometry thiab hnav thaum cov tshev no tsis piav qhia qhov poob. Hloov cov khoom siv tsuas yog tom qab txheeb xyuas qhov txwv kev ua haujlwm.

Xaiv ib tug PVC ua npuas ncauj board conical twin ntsia hlau chim nyob ib ncig ntawm lub formulation, cov uas twb muaj lawm tshuab interfaces thiab ntsuas coj. Paub meej tias daim duab tiav ua ntej xaiv ib txoj kab uas hla. Qhia meej txog nitriding lossis bimetal tiv thaiv los ntawm kev tsim cov dej num, tom qab ntawd pom zoo rau qhov kev lees paub siv koj daim ntawv qhia board tiag tiag thiab cov kev xav tau zoo.
