Siv cov yas extrusion kab hauv profiles

Profiles ntawm ntau hom duab yog extruded. Profiles feem ntau yog cov duab uas tsis yog ib puag ncig lossis tsis sib luag. Txawm li cas los xij, muaj qee qhov tshwj xeeb uas cov khoom sib npaug lossis cov khoom sib npaug, xws li capillary tubing, feem ntau hu ua profile. Profiles tuaj yeem yog khoom, hollow, los yog ua ke ntawm cov khoom thiab hollow. Cov duab nrov muaj xws li ntau qhov hollow seem, xws li hauv qhov rais thav duab profile, tapes, edgings, thiab gaskets, nrog rau kev sib xyaw ntawm cov pas nrig nrog cov hlaws sib txawv, thiab cov qauv duab hauv daim ntawv ntawm T, U, I, lossis H, squares, thiab lwm yam.

Yooj yim thiab nruj PVC yog cov yas nrov tshaj plaws siv. Lwm cov yas loj ua tiav yog HDPE, LDPE, PP, PMMA, thiab PS. Txawm li cas los xij,

TPs sib txawv yog siv los ua kom tau raws li qee qhov kev ua tau zoo thiab cov nqi xav tau.

1.1 Cov ntaub ntawv shrinking rau extrusion

TP cov ntaub ntawv poob qis thaum ua tiav. Yog tias koj muaj kev xaiv, siv cov yas uas muaj qhov tsawg kawg nkaus shrinkage. Tus nqi ntawm qhov shrinkage nyob ntawm cov ntaub ntawv uas tau ua tiav thiab cov kev khiav hauj lwm tsis tau teeb tsa thaum lub sij hawm extrusion (rov qab siab nyob rau hauv tuag, kos down ratio, tus nqi ntawm kab ceev, txias tej yam kev mob, thiab lwm yam). Txhawm rau them nyiaj rau qhov shrinkage, qhov qhib qhov tuag feem ntau yog ua oversize; qhov sib piv thiab lwm yam kev ua haujlwm tuaj yeem cuam tshuam txo qis qhov shrinkage. Txawm li cas los xij, nrog kev tswj hwm lub tshuab tsis zoo, cov kab no tuaj yeem ua rau muaj teeb meem, xws li kev tsim cov kev ntxhov siab tsis zoo hauv qhov profile, hloov cov khoom siv tshuab, thiab lwm yam.

1.2 Deal nrog shrinkage rau extrusion

Qhov kev ua tau zoo tshaj plaws rau qhov teeb meem shrinkage yog kom oversize lub shrinkage yam yuav tsum tau siv. Cov lus qhia zoo tshaj plaws yog muaj kev paub txog kev ua cov khoom siv tib yam, extruding zoo ib yam thiab loj profile. Ib qho kev qhia dav dav rau kev loj hlob yog raws li hauv qab no: nylon ntawm 20%, HDPE ntawm 20%, LDPE ntawm 15%, hloov pauv PVC ntawm 15%, PVC tawv ntawm lo%, CA ntawm lo%, thiab PS ntawm 10%. Table 1.1 kam rau ua muab piv txwv ntawm kam rau siab rau thaum extruding profiles nrog ntau hom yas nrov.

PROCESSING CHAW UA HAUJ LWM

Qee qhov profile tsuas yog xav tau huab cua-floating suab thaum txias rau hauv dej. Txawm li cas los xij, feem ntau cov ntaub ntawv hla dhau los ntawm cov cuab yeej shaping uas tuaj yeem suav nrog lub tshuab nqus tsev 'lub thawv' uas tau tsim tshwj xeeb rau cov profiles (Fig.1.2). Cov profile txuas ntxiv mus rau hauv lub qhov dej, hauv qab cov dej ntws, thiab / lossis dhau ntawm txoj siv conveyor nrog lossis tsis muaj kiv cua kom txias hauv huab cua. Rau qee cov duab, nrog rau cov duab xws li rods, U-channels, thiab

profiles nrog nruj sab nraud qhov yuav tsum tau muaj,

cua thiab dej txias calibration tes tsho los yog lub tshuab nqus tsev calibration sizing daim hlau yog siv. Lub tes tsho sizing / cuab yeej tuaj yeem ua kom sib haum rau qhov shrinkage ntawm cov yas ua tiav.

1-2 Profile tuag hauv kab extrusin

Qhov rai ncej precision ceev kab

1-3 Piv txwv ntawm PVC cross sets rau qhov rais thav duab fabricating

1-4 Piv txwv ntawm qhov profile tuag ua raws nrog lub tshuab nqus tsev vacuum calibrator

Ib qho piv txwv qhov twg lub tes tsho qhuav calibration yog qhov tseem ceeb heev yog thaum extruding complex qhov rais ncej PVC profiles Daim duab 1.3 qhia

hla ntu ntawm ib leeg thiab ntau chav tsim qauv.Rigid mechanical thiab lub cev xav tau, uas suav nrog qhov ntev, yuav tsum tau ua raws.

Lub kaw lus rau precision profile kab yog qhov hauv qab no:

(1) ib leeg lossis ntxaib ntsia hlau extruder;

(2) ib qho zoo heev tsim streamline extrusion kab;

(3) ib tug series ntawm 2,3, los yog 4 lub tshuab nqus tsev calibrators uas zoo ib yam li lub tes tsho sizing nyob rau hauv lub tshuab nqus tsev tank, uas yog mounted rau ib tug tshwj xeeb tsim calibrator sawv los muab tshwj xeeb metered nqus tsev vacuum thiab dej txias rau lub calibrators;

(4) cua txias thiab radiant cua sov sawv kom qhov profile ncaj;

(5) lub ruber nrog rub lub peev xwm los ntawm 24.5 tonne;

(6) ib tug txhim khu kev qha cutoff saw; thiab

(7) ib tug stacking system.

Tus yuam sij rau qhov no lub tes tsho qhuav calibration system yog tus tsim ntawm extrusion tuag, nws loj kev sib raug zoo rau lub calibrator, thiab qhov luaj li cas ntawm lub calibrator uas yog tsim los tso cai rau lub shrinkage ntawm tej compound raug extruded (Fig. 1.4). Lub extrusion tuag feem ntau yog tsim los ntawm cov hlau tsis muaj steel thiab tsim los them nyiaj siab tshaj plaws hauv streamlining. Tsis muaj qhov chaw tuag lossis eddies tuaj yeem zam tau. Cov tuag yog tsim los faib cov yas kom puv tag nrho cov phab ntsa thiab sab hauv webs uniformly. Feem ntau cov webs tsis yog rau lub zog ntawm cov qauv, tab sis kom ua tiav qhov sib npaug ntawm cov dej ntws ntawm cov yas yaj mus rau qhov qhib qhov ncauj.

Tie Standar thiab kev cai tuag

Muaj qhov kev lag luam txheeb xyuas raws li tus qauv thiab kev cai tuag. Cov txheej txheem tuag tau tsim tau zoo, tsim cov khoom lag luam xws li rods, T-shapes, siv tawv / tapes, straws, thiab lwm yam. Lawv suav nrog cov qauv yooj yim rau cov duab.Cov kev cai tuag feem ntau yog cov hom uas txwv ntau lawm thiab feem ntau yog cov neeg siv khoom. Txij li thaum lub lag luam no suav nrog kev siv luv luv ntawm ntau qhov sib txawv zoo li tus profiles, ntau qhov kev tuag (phaj tuag) yog cov qauv tsim thiab tsim khoom, thiab tsis streamlined.

Qhov tsim ntawm hom tuag nyob ntawm seb cov khoom puas yog hollow lossis compact / khoom. Tsis tas li ntawd seb tus ntoo khaub lig yog qhov yooj yim los yog complex.Lub hom phiaj yog tsim kom tsim nyog tshaj plaws yaj ntws channel uas yog yuav tsum tau streamlined thiab ua tau raws li qhov tsawg kawg nkaus thiab txawm lub sij hawm nyob. Nws kuj yuav tsum tau ua kom tau raws li qhov yuav tsum tau them nyiaj rau qhov down-kem post extrusion dimensional hloov uas tshwm sim. Nrog rau tag nrho cov xwm txheej no, ntxiv tias qhov tawm ntawm cov yaj yog nyob ntawm qhov sib xws ceev thiab kub.

Ib tug yuav hais tias cov yas extruded profiles nyob ib ncig ntawm peb. Lawv siv nyob rau hauv ntau lub khw, xws li lub tsev thiab kev tsim kho, cov khoom siv hluav taws xob thiab hluav taws xob, tsheb thauj mus los (pib, dav hlau, thiab lwm yam), cov cuab yeej siv kho mob, cov khoom siv teeb pom kev zoo, thiab lwm yam. Cov khoom tshwj xeeb muaj xws li cov qhov rais raws, nag gutters, lub tsev sab hauv, nws pib. qhov rooj trims, garage overhead qhov rooj, gaskets, seals, thiab lwm yam. Txhawm rau nthuav dav kev lag luam rau lub qhov rais thav duab uas twb muaj lawm, qee cov txheej txheem tau nthuav tawm cov txheej txheem nyuaj dua los tshem tawm cov teeb meem xws li cov av noo hauv tsev vim PVC qhov rai thav ntawv tsis haum nruj heev.
