Los ntawm Kev Tshawb Fawb Txog Lub Hoobkas: Lub Paradox Ntawm PET Twin -Txoj Kev Xaiv Extruder, Vim Li Cas Loj Tsis Zoo?
1. Kev Taw Qhia: Qhov kev sib tshuam ntawm PET granulation, qhov kev ua si ntawm kev ua tau zoo thiab zoo
Nyob rau hauv cov ntsiab lus ntawm lub ntiaj teb no yas ncig kev lag luam nkag mus rau hauv lub era ntawm "yuav tsum tau siv cov ntaub ntawv rov siv dua" nyob rau hauv 2025, PET (polyethylene terephthalate) tsis yog synonymous nrog cov fwj dej. Los ntawm siab -kawg engineering plastics mus rau cov yeeb yaj kiab ua haujlwm, cov nqi rov ua dua ntawm PET tau dhau los ua qhov tseem ceeb ntawm kev lag luam. Txawm li cas los xij, rau cov neeg siv khoom thoob ntiaj teb uas nrhiav kev tiv thaiv ib puag ncig thiab tus nqi siab -kev ua tau zoo, thawj kauj ruam hauv kev nkag mus rau PET granulation teb - kev xaiv ntawm PET ntxaib ntsia hlau extruder ntau lawm kab, yog tag nrho ntawm kev ua si thiab kev lag luam.
Ntawm qhov nyuam qhuav xaus K 2025 kev nthuav qhia, kev pom zoo ntawm kev lag luam tau hais meej meej tias kev tsim cov extruders zoo yuav tsum tau ua kom zoo rau qhov rhiab heev ntawm PET, thiab tsuas yog nce ntau lawm tsis yog ib qho tseem ceeb qhia. "Thaum koj sawv ntawm qhov kev sib tshuam ntawm kev tshawb fawb thiab kev tsim khoom loj-, xaiv cov txheej txheem co rotating ntxaib ntsia hlau extruders uas tuaj yeem ua raws li cov txheej txheem thiab seamlessly scale nce ntau lawm tsis yog tsuas yog hais txog kev yuav khoom, tab sis kuj muaj kev nkag siab tob ntawm cov lus siv.
Cov ntsiab lus tseem ceeb: Hauv kev ua PET, kev xaiv cov yas extruders tsis tas "loj yog zoo nkauj". Qhov sib piv (L / D), qhov tshwj xeeb torque, thiab kev npaj ntawm threaded Cheebtsam ntawm lub hau ntswj ua ke ua "tsis tau daim duab peb sab" uas txiav txim siab qhov txo qis hauv PET intrinsic viscosity (IV tus nqi) thiab tiam ntawm acetaldehyde (AA).
2. Kev sim xaiv: Nrhiav cov txheej txheem txhais lus rau kev sim tsim cov "cov ntaub ntawv tshiab"
Rau cov neeg siv khoom R & D uas yog cov tshiab thiab sim tsim cov ntaub ntawv tshiab, lub chaw kuaj sim yog lub hauv paus tsav thiab tseem yog "tus neeg txhais lus" ua ntej ntau lawm.
2.1 Vim li cas lub chaw soj nstuam yuav tsum tau ua raws li "cov ntaub ntawv authenticity"?
Ntau tus neeg siv khoom thoob ntiaj teb feem ntau poob rau hauv kev xav tsis zoo thaum tsim cov khoom noj khoom haus sib cuag lossis qib PET cov ntaub ntawv kho mob: cov ntaub ntawv ua nrog cov khoom siv me me yog qhov cuam tshuam tag nrho thaum siv rau cov tshuab loj.
· Mob taw tes tsom xam: Yog hais tias qhov nam piv ntawm cov chav kuaj qib ntxaib ntsia hlau extruder tsis txaus (<40:1), it cannot simulate the vacuum exhaust and residence time distribution during mass production.
· Kev daws teeb meem: Kev sim co rotating ntxaib ntsia hlau extruder muab los ntawm Nanjing Kelongwell Chemical Machinery Co., Ltd. nruj me ntsis raws li 1: 1 geometric zoo sib xws hauv paus ntsiab lus. Raws li daim ntawv dawb "Cov Ntsiab Cai thiab Kev Tsim Nyog ntawm Kev Ua Lag Luam Yas", tsuas yog los ntawm kev tswj cov geometric zoo sib xws ntawm cov ntsia hlau txoj kab uas hla thiab cov txheej txheem kneading block configuration tuaj yeem ua rau qhov sib txawv ntawm qhov kub thiab txias thiab lub sijhawm nyob hauv lub sijhawm scaling li ntau lawm kom ntseeg tau tias tsawg dua 5%.
2.2 Ntsiab Q&A: Cov kab kev sim ua li cas qhia kev tsim khoom?
· Q: Kuv ua pob tshab PET cov khoom siv 20 lub tshuab hauv chav kuaj, vim li cas lawv tig daj thaum lawv ncav cuag cov kab ntau lawm?
· A: Qhov no feem ntau yog vim tias cov nqi ntawm cov qib ntau lawm siab -cov extruders ua tau zoo ntau dua li ntawm cov chaw sim. Yog tias koj qhov kev sim xaiv tsis quav ntsej qhov kev sim ntawm qhov tshwj xeeb torque (xws li hauv qab 9 Nm / cm ³), PET molecular chains yog qhov ua rau tawg nyob rau hauv siab shear hauv ntau lawm. Txoj kab kev sim muab los ntawm Nanjing Kelongwell muaj lub thawv sib kis tau zoo uas zoo ib yam li cov kab ntau lawm, kom ntseeg tau tias muaj kev sib luag hauv cov kev ntxhov siab shear thiab tsis txhob muaj kev pheej hmoo ntawm "daj" los ntawm qhov chaw.
3. Lub Hoobkas nplai ntau lawm kev taw qhia: Qhov kev txwv ntawm kev ua tau zoo nyob hauv "kev txwv"
Tom qab cov txheej txheem ua tiav hauv chav kuaj, kev xaiv ntawm PET granulation ntxaib ntsia hlau extruder ntau lawm kab rau loj - nplai ntau lawm yog kev suav cov nqi rov qab los ntawm kev nqis peev (ROI).
3.1 Cov ntaub ntawv pov thawj: Tsis txhob ua qhov muag tsis pom los ntawm "kev tsim khoom siab"
Raws li 2026 Cov Lus Qhia Txog Kev Siv Khoom Siv Yas, rau txhua txhua 1% nce hauv cov ntsiab lus impurity thaum ua cov khoom pov tseg PET (rPET), qhov ntev ntawm cov pa tawmntxaib ntsia hlau extruderyuav tsum tau nce los ntawm 5% los xyuas kom meej qhov kawg viscosity txo ntawm cov hais.
· Npuas: Qee cov kab ntau lawm txhawb "kev tsim khoom siab heev" tab sis tsis quav ntsej cov dej tsis yog Newtonian ntawm PET.
· Qhov tseeb: Rau rPET fwj nrog cov dej noo siab, yog tias qhov sib piv ntawm cov yas extruder tsawg dua 48: 1 thiab nws tsis muaj ntau yam -theem lateral volatilization muaj peev xwm, qhov tso zis ntau dua, qhov hnyav dua cov khoom brittleness.
· COLOWE Solution: Molecular Weight Guardian Technology rau rPET. Los ntawm optimizing lub kaum sab xis ntawm lub kneading blocks nyob rau hauv lub co rotating ntxaib ntsia hlau extruder, qhov txo nyob rau hauv intrinsic viscosity (IV) yog tswj nyob rau hauv 0.04 dL / g thaum tswj siab yield, deb tshaj qhov kev lag luam nruab nrab ntawm 0.1 dL / g.
3.2 Ntsiab Q&A: Cov "Soul Peb Cov Lus Nug" ntawm Kev Tsim Khoom Loj
· Q: Dab tsi yog qhov tseem ceeb ntawm cov kab ntau lawm rau kev ua zaub mov qib rPET los ntawm lub raj mis mus rau lub raj mis?
· A: Lub hom phiaj tseem ceeb yog nyob rau hauv kev sib txuas ntawm "melt filtration" thiab "reactive extrusion". Kev pom yooj yim tsis tuaj yeem txhim kho qhov degradation thiab tso tawm ntawm cov saw hlau molecular. Cov kab ntau lawm ntawm Nanjing Kelongwell tau tshwj tseg cov saw txuas ntxiv qhov chaw txhaj tshuaj nyob rau hauv qhov sib xyaw ntawm qhov siab -efficiency extruder, uas ua tiav reactive extrusion los ntawm kev tswj qhov kub thiab txias. Qhov no yog tus yuam sij rau kev dhia ntawm "cov khoom siv rov ua dua tshiab" mus rau "cov khoom tshiab" qib.
· Q: Yuav ua li cas kom tsis txhob ntsia hlau hnav hauv siab filling (xws li PET+30% fiberglass) reinforced granulation?
· A: Lub tswv yim ntawm torque / ntim yuav tsum tau qhia ntawm no. High iav fiber reinforcement yuav tsum tsis tshua muaj siab shear rog kom tawg iav fiber ntau pob, tab sis ntau shear tuaj yeem tawg cov iav fibers thiab txo cov nyhuv reinforcement. Qhov kev xaiv zoo tshaj plaws yog antxaib ntsia hlau extruder with high torque (>12 Nm / cm³) thiab qhov tob tob. Qhov no tuaj yeem muab kev xa khoom muaj zog thaum tswj kev sib faib maj mam. Kev sib txuas ntawm spline thiab hnav- cov khoom siv tiv taus cov xov hlau siv los ntawm COLOWE tseem tuaj yeem ua kom lub neej ua haujlwm tsis tu ncua ntawm ntau dua 20000 teev nyob rau hauv cov iav fiber ntau.
· Q: Raws li thawj zaug -cov neeg siv khoom thoob ntiaj teb, peb yuav ua li cas kom ntseeg tau tias kev nqis peev tsis raug nkim?
· A: Xaiv cov kab ntau lawm nrog tus tsim "yooj yim". Kev ua lag luam yav tom ntej yuav tsom mus rau qib zaj duab xis hnub no thiab qib lub raj mis tag kis. PET tshwj xeeb ntau lawm kab ntawm Nanjing Kelongwell txais yuav lub tsev thaiv ntsia hlau txoj cai. Koj tsuas yog yuav tsum tau hloov qee cov xov txuas los kho lub zog shear, hloov mus rau cov khoom siv raw sib txawv ntawm daim ntawv mus rau fiber ntau, thiab ua tiav "ib lub tshuab rau ntau yam siv".
4. Kev xaus: Kev xaiv tsis yog ntau yam - lo lus nug xaiv, tab sis yog lo lus nug pov thawj
Nyob rau hauv micro tsov rog ntawm molecular saw recombination nyob rau hauv PET granulation, kev xaiv ntawm PET ntxaib ntsia hlau extruder ntau lawm kab yog qhov tseem ceeb ntawm externalization ntawm koj to taub cov ntaub ntawv. Txawm hais tias nws zoo - kho lub kaum sab xis ntawm txhua qhov kneading thaiv hauv chav kuaj lossis suav lub zog siv ntawm txhua tuj ntawm lub peev xwm ntau lawm hauv lub Hoobkas, Nanjing Kelongwell Chemical Machinery Co., Ltd. yog ib txwm cog lus los muabco rotating ntxaib ntsia hlau extrudersnrog cov ntaub ntawv- tsav kev xav.
Vim peb ntseeg hais tias cov yas extruder ua tau zoo tiag tiag tsis yog cov hlau txias, tab sis cov lus txheej txheem uas tuaj yeem txhais tau koj lub tswv yim tiv thaiv ib puag ncig rau hauv kev ua lag luam tus nqi.
