Qhov kev ncua deb ntawm "ob- txheej board" thiab "engineered co-extrusion" yog ntsuas nyob rau hauv cap chemistry, daim ntawv cog lus lub zog, txheej thickness uniformity, thiab tus neeg muag khoom txaus siab los sau cov variables no es tsis txhob gesturing ntawm lo lus "co-extruded" thiab mus rau tus nqi.
Kab lus no tshuaj xyuas qhov co-extruded PVC board tiag tiag yog li cas, yuav ua li cas qhia cov txheej txheem ua haujlwm los ntawm cov tshuaj pleev ib ce, thiab qhov twg co-extrusion daws cov teeb meem tiag tiag piv rau qhov uas nws siv cov kev daws teeb meem zoo rau cov teeb meem uas pheej yig dua tuaj yeem daws tau.
I. Lub Rooj Tswjhwm Saib Nrog Ob Tus Kheej: Dab tsi "Co-extruded" Tiag Tiag Thaum Tuag
Nyob rau hauv tus txheej txheem ua npuas ncauj extrusion kab, ib tug formulation nkag mus rau hauv lub extruder, ib tug yaj kwj tawm ntawm lub tuag, thiab ib tug cov ntaub ntawv tsim lub rooj tsavxwm. Qhov saum npoo thiab qhov tseem ceeb yog tshuaj lom neeg zoo ib yam. Txhua qhov sib txawv ntawm qhov ntom ntom ntawm daim tawv nqaij thiab qhov chaw nruab nrab yog ib qho kev mob tshwm sim ntawm lub cev ntawm kev ua kom txias sai ntawm phab ntsa tuag, tsis yog kev xaiv tsim. Nyob rau hauv ib co-extrusion kab, ob extruders cais pub ob formulations sib txawv nyob rau hauv ib tug feedblock los yog multi-manifold tuag, qhov chaw uas lawv ntsib raws li nyias txheej txheej thiab tawm cov tuag raws li ib tug unified daim ntawv nrog discrete, txhob txwm sib txawv nto thiab core compositions.
Qhov kev sib tw engineering yog kev dag ntxias yooj yim los piav qhia thiab nyuaj rau kev ua tiav. Ob lub kwj deg yuav tsum tuaj txog ntawm qhov tuag ntawm qhov kub thiab txias txaus uas lawv ntws ua ke yam tsis muaj thermal shock ntawm lub interface. Lawv yaj viscosities yuav tsum zoo ib yam txaus uas ib txheej tsis thawb los ntawm lwm yam, tsim thickness variation los yog, nyob rau hauv heev mob, ib tug tseem ceeb uas punches los ntawm lub hau thiab exposes nws tus kheej ntawm daim ntawv nto. Lawv cov thermal expansion coefficients yuav tsum tau ua kom zoo txaus tias daim ntawv tiav tsis curl raws li nws txias - lub hau txheej uas shrinks ntau tshaj li cov tub ntxhais rub lub rooj tsavxwm concave ntawm lub hau sab; lub hau uas shrinks tsawg pushes nws convex. Thiab tag nrho cov kab ke yuav tsum khiav ntawm ib txoj kab ceev uas yog kev lag luam, uas txhais tau hais tias lub sij hawm nyob rau ob lub melts los ua ib daim ntawv cog lus ntawm lub interface yog ntsuas nyob rau hauv feem ntawm ib tug thib ob.
Thaum tag nrho cov kev hloov pauv no tau tswj hwm hauv cov lus qhia tshwj xeeb, qhov tshwm sim yog lub rooj tsav xwm uas lub hau txheej thiab cov tub ntxhais ua haujlwm ua ib qho kev tsim qauv, thiab lub hau muab cov cuab yeej ntog uas cov khoom tseem ceeb tsis tuaj yeem ua tiav ntawm tus nqi sib npaug. Thaum ib qho ntawm lawv tawm ntawm qhov ntau, qhov tshwm sim yog lub rooj tsavxwm uas zoo nkaus li zoo rau hauv pem teb warehouse thiab ua tsis tiav hauv kev tsim khoom - lub hau delaminates thaum lub sij hawm routing, los yog hlwv nyob rau hauv ib tug UV tua teeb, los yog cais los ntawm cov tub ntxhais thaum lub sij hawm thermoforming thaum ob txheej stretch ntawm tus nqi sib txawv.
Ib co-extrusion ntau lawm kab nrog cais extruders pub ib leeg tuag los ua ob- txheej ntawv nrog txawv cap thiab core formulations.
II. 0.05 hli Polymer txheej uas hloov txhua yam hais txog lub Rooj Tswjhwm Saib
Lub hau txheej ntawm lub co-extruded PVC board feem ntau yog nruab nrab ntawm 0.05 hli thiab 0.50 hli tuab- kwv yees li cov thickness ntawm ib daim ntawv ntawm chaw ua hauj lwm ntawv nyob rau hauv qis kawg thiab ib daim credit card nyob rau hauv siab kawg. Qhov zoo li tsis tseem ceeb ntawm cov khoom no yog lub luag haujlwm tsis txaus ntseeg. Nws yog qhov chaw uas tau txais tus cwj mem, qhov thaiv thaiv UV, daim tawv nqaij uas tiv thaiv khawb, thiab lub ntsej muag kom zoo nkauj uas tus neeg siv kawg yuav saib rau lub neej ntawm cov khoom. Lub hau txheej uas nyias dhau, lossis tsis zoo, lossis ua los ntawm kev ua tsis ncaj ncees lawm, ua rau txhua qhov ntawm cov haujlwm no.

V. Daim Ntawv Cog Lus Tsis muaj leej twg kuaj kom txog thaum lub kaus mom tshem tawm
Interlayer adhesion-lub zog ntawm daim ntawv cog lus ntawm lub hau thiab lub hauv paus- yog qhov tshwj xeeb sib txawv uas cais cov kev ua haujlwm co-extrusion los ntawm cosmetic ob- txheej tsim, thiab nws yuav luag tsis tau kuaj los ntawm tus neeg yuav khoom. Qhov omission yog to taub. Kev kuaj adhesion yuav tsum tau txiav ib tug ntoo khaub lig-section, sim tev lub hau ntawm lub hauv paus nrog lub zog tswj, thiab tshuaj xyuas hom tsis ua hauj lwm los txiav txim seb qhov kev sib cais yog nplaum, ntawm qhov sib txuas, los yog cohesive, nyob rau hauv ib qho ntawm cov txheej. Tsis muaj qhov no tuaj yeem ua tiav nrog daim kab xev ntsuas thiab kev tshuaj xyuas pom hauv qhov chaw txais.
Tab sis interlayer adhesion yog qhov tsis ua hauj lwm uas ua rau cov nyiaj lav lav zoo tshaj plaws. Ib co-extruded board uas tau xa mus rau hauv ntawv, pleev xim rau, thiab ntsia rau ntawm lub khw muag khoom uas tig mus rau sab hnub poob rau yav tav su hnub yuav muaj kev caij tsheb kauj vab txhua hnub. Lub hau thiab cov tub ntxhais nthuav dav thiab cog lus ntawm tus nqi sib txawv me ntsis -ASA muaj qhov sib npaug ntawm cov kab hluav taws xob thermal nthuav tawm kwv yees li 20 txog 30 feem pua qis dua li PVC ua npuas ncauj. Txhua lub voj voog siv ib qho kev nyuaj siab rau lub interface. Yog hais tias lub interlayer daim ntawv cog lus yog marginal, qhov kev ntxhov siab accumulates raws li cov microscopic sib cais uas loj hlob mus rau hauv cov hlwv pom, thiab nws thiaj li mus rau hauv cap delamination tshaj ib cheeb tsam ntsuas hauv square centimeters es tsis yog square millimeters.
Dab tsi ua rau hom kev ua tsis tiav tshwj xeeb yog insidious yog nws ncua sijhawm. Lub co-extruded board nrog tsis zoo interlayer adhesion dhau los ntawm kev tshuaj xyuas, ua kom huv si los ntawm kev khiav thiab luam ntawv, thiab xa mus rau cov neeg siv khoom saib tsis zoo. Lub delamination tshwm sim ntau lub hlis tom qab, tshwm sim los ntawm cov txiaj ntsig ntawm thermal cycles uas tsis muaj lub Hoobkas kuaj rov ua dua. Thaum lub sij hawm qhov tsis ua hauj lwm pom, lub rooj tsavxwm tau tsim, xa khoom, teeb tsa, thiab them nqi- thiab cov nqi hloov pauv tsis yog tsuas yog cov khoom siv xwb tab sis kev tsim khoom, kev luam ntawv, kev xa khoom, kev teeb tsa, thiab kev puas tsuaj rau cov neeg siv khoom.
Ob daim tshev uas tus neeg muag khoom yuav tsum tuaj yeem dhau:
Nug rau 90-degree tev cov txiaj ntsig ntawm ASTM D6862 lossis tus qauv sib npaug, nrog rau hom tsis ua haujlwm tau sau tseg -kev ua tsis tiav hauv cov tub ntxhais kawm tau txais; nplaum tsis ua hauj lwm ntawm lub hau -core interface tsis yog. Qhov thib ob, nug txog kev ntsuas cua sov: lub rooj tsavxwm yuav tsum muaj sia nyob tsawg kawg tsib lub voj voog ntawm -20℃thiab +60℃yam tsis muaj blistering, delamination, lossis ntug sib cais. Ib tus neeg muag khoom uas tsis tuaj yeem muab cov txiaj ntsig kev xeem yog muag co-extrusion raws li lub tswv yim, tsis yog cov khoom lag luam uas tau lees paub.
VI. Sab hauv thiab sab nraum zoov yog cov rooj sib txawv - Txawm tias lawv zoo ib yam
Ib tug dawb co-extruded PVC board nrog lub PVC hau thiab ib tug dawb co-extruded PVC board nrog ib tug ASA cap zoo tib yam nyob rau hauv warehouse teeb pom kev zoo. Lawv yog cov xim tib yam, tib qib gloss, tib tuab, tib qhov ntom. Qhov sib npaug ntawm qhov pom ntawd yog lub hauv paus ntawm kev rov ua cov khoom lag luam tsis ua haujlwm: sab hauv tsev - pawg thawj coj tau muag, xa khoom, tsim khoom, thiab muab tso rau hauv daim ntawv thov sab nraum zoov vim tsis muaj leej twg hauv cov saw hlau ntsia yav dhau los qhov tshwm sim rau lub kaus mom chemistry. Lub rooj tsavxwm zoo lawm. Nws ua txoj cai.
