Hauv kev lag luam extrusion txhuas, lub sijhawm uas ib daim profile tawm ntawm lub pwm ntawm qhov kub txog 500–550 ° C yog lub sijhawm tseem ceeb hauv cov txheej txheem tsim khoom. Nyob rau theem no, cov txhuas kub, ib nrab khov kho muaj kev phom sij rau kev puas tsuaj ntawm qhov chaw, kev hloov pauv, thiab kev khawb - qhov tsis zoo uas tuaj yeem ua rau cov khoom kawg tsis siv tau rau cov ntawv thov muaj nqis xws li cov khoom siv anodized lossis cov khoom siv tsheb.

A felt conveyor siv rau txhuas extrusiontsis yog tsuas yog ib txoj kev thauj mus los xwb; nws yog ib qho tseem ceeb uas tiv thaiv kev ua tiav ntawm cov khoom, txo lub sijhawm tsis ua haujlwm, thiab ua kom zoo dua qhov kev xa khoom. Tsis zoo li cov hlau slats ib txwm muaj lossis cov siv ntaub, cov siv uas muaj koob tsis kawg muab kev sib xyaw ua ke ntawm kev tiv taus cua sov, kev tiv thaiv nto, thiab kev ruaj khov ntawm qhov ntev.

Rau cov thawj coj cog qoob loo, cov kws ua haujlwm txij nkawm, thiab cov kws tshwj xeeb hauv kev yuav khoom, kev xaiv cov siv conveyor uas muaj ntaub zoo - txawm tias PBO, Kevlar, Nomex, lossis Polyester - cuam tshuam ncaj qha rau cov nqi pov tseg, lub neej pwm, thiab tag nrho cov khoom siv ua haujlwm tau zoo (OEE). Phau ntawv qhia no muab kev tshuaj xyuas tob txog cov siv siv hauv kev rho tawm txhuas, qhia txog cov ntaub ntawv tshawb fawb, thaj chaw siv, thiab cov lus qhia txog kev siv tshuab los pab koj txiav txim siab yuav khoom kom paub zoo.

Nkag Siab Txog Cov Txheej Txheem Extrusion: Cov Cheeb Tsam Kub thiab Cov Kev Xav Tau

Lub rooj khiav tawm, qhov twg cov profiles raug thauj mus los thiab txias, tau muab faib ua thaj chaw kub sib txawv. Txhua theem xav tau ib hom siv txoj siv sia tshwj xeeb los tswj cov cua sov sib txawv thiab kev ntxhov siab ntawm lub cev.

Kev Xaiv Khoom Siv: PBO, Kevlar, Nomex, thiab Polyester

Qhov kev xaiv ntawm cov khoom siv fiber txiav txim siab qhov kev ua tau zoo ntawm txoj siv sia, lub neej ntev, thiab kev siv nyiaj tsim nyog. Nov yog kev rhuav tshem ntawm plaub yam khoom siv tseem ceeb siv hauv cov siv sia aluminium extrusion:

1. PBO (Polybenzoxazole) - Thaj Chaw Kub Heev

PBO (feem ntau hu ua Zylon) sawv cev rau qhov siab tshaj plaws ntawm kev tiv taus cua sov rau cov siv tawv. Nws yog tsim tshwj xeeb rau qhov chaw ib puag ncig hnyav tam sim ntawd tom qab nias extrusion.

• Kev Tiv Thaiv Kub: Txog li 600 ° C tas li. Qhov no yog tib yam khoom siv uas muaj peev xwm tiv taus qhov cua sov thawj zaug yam tsis ua rau puas tsuaj lossis hlawv qhov chaw txhuas.
• Daim Ntawv Thov: Cov tshuab muaj peev xwm siab (> 2000T), cov ntaub ntawv loj thiab nyuaj, thiab "pem hauv ntej kawg" ntawm lub rooj khiav tawm.
• Cov Zoo: Kev tiv taus cua sov zoo heev, elongation tsawg, thiab tsis muaj cim ntawm qhov chaw. Cov siv PBO feem ntau muaj xim txiv kab ntxwv lossis xim av.
• Cov Lus Qhia Tseem Ceeb: Qhov tuab ntawm 4mm txog 12mm; qhov dav dav feem ntau yog txog li 2,200mm.

2. Kevlar (Para-Aramid) - Thaj Chaw Kub Siab

Kevlar yog ib qho khoom siv ua haujlwm hauv kab extrusion, muab qhov sib npaug ntawm kev tiv taus cua sov siab, kev ruaj khov, thiab kev siv nyiaj tsawg.

• Kev Tiv Thaiv Kub: Txog li 480–500 ° C (ncov / luv luv) thiab ~ 200 ° C txuas ntxiv mus.
• Daim Ntawv Thov: Cov rooj txias thawj zaug thiab theem ob, cov rooj tuav / hloov chaw.
• Cov Zoo: Kev tiv taus kev sib txhuam zoo heev thiab lub zog tensile. Tiv thaiv kev ncab thaum muaj kev thauj khoom hnyav. Cov siv sia Kevlar feem ntau yog xim daj.
• Cov Lus Qhia Tseem Ceeb: Feem ntau muaj nyob rau hauv thicknesses ntawm 5mm mus rau 14mm thiab dav txog li 3,000mm.

3. Nomex (Meta-Aramid) - Thaj Chaw Kub Nruab Nrab

Nomex siv rau qhov kub tseem ceeb tab sis tsis kub heev, xws li kev ua haujlwm downstream.

• Kub thiab txias: Txog li 280 ° C.
• Daim Ntawv Thov: Cov cheeb tsam tom qab lub tshuab ncab, cov rooj pom, thiab kev hloov ua ntej txiav.
• Qhov Zoo: Kev ruaj khov zoo nrog cov qauv qis dua. Feem ntau dawb. Haum rau feem ntau cov qauv extrusion profiles.
• Cov Lus Qhia Tseem Ceeb: Qhov ceev feem ntau yog txij li 0.15 txog 0.45 g / cm³.

4. Polyester - Thaj Chaw Kub Qis

Cov siv polyester yog qhov kev xaiv pheej yig rau cov theem kawg ntawm kab extrusion.

• Kev Tiv Thaiv Kub: Txog li 150–180 ° C.
• Daim Ntawv Thov: Cov rooj pom, cov chaw teeb tsa, chaw cia khoom, thiab cov kab npaj anodizing.
• Cov Zoo: Tus nqi qis dua, yooj yim hloov, thiab muab ib qho chaw tsis muaj cim. Feem ntau yog xim beige lossis dawb.
• Cov Lus Qhia Tseem Ceeb: Feem ntau muaj nyob rau hauv cov tuab xws li 3mm, 5mm, 6mm, thiab 8mm.

Sab saum toj 5 Qhov Zoo Tshaj Plaws ntawm Seamless Endless Felt Belts

Yuav kom tiv thaiv cov txhuas profiles muaj nqis los ntawm qhov tsis zoo, txoj siv sia nws tus kheej yuav tsum zoo tag nrho. Nov yog vim li cas kev tsim kho tsis kawg uas muaj koob muaj zog ua tau zoo dua li lwm txoj hauv kev laced lossis spliced:

• Tsis Muaj Qhov Tsis Zoo Ntawm Qhov Chaw (Tsis Muaj Kos): Qhov txiaj ntsig tseem ceeb yog qhov chaw du thiab tsis muaj cim uas tiv thaiv kev khawb thiab kev lwj ntawm cov khoom extrusion zoo heev (piv txwv li, cov chaw polished lossis anodized). Qhov no ua kom muaj cov zis zoo thiab txo cov nqi pov tseg.
• Kev Tshem Tawm Cov Qhov Tsis Muaj Zog: Cov siv sia uas muaj hlua khi lossis sib txuas ua ke tsim ib qho "qhov tsis muaj zog" uas yooj yim puas tsuaj thaum muaj qhov kub thiab txias siab. Cov siv sia uas tsis muaj qhov sib txuas faib kev ntxhov siab kom sib npaug, ua rau lub neej ua haujlwm ntawm txoj siv sia ntev dua.
• Kev Nyhav Siab & Kev Ntev Qis: Cov siv sia uas muaj koob, tshwj xeeb tshaj yog cov uas muaj cov fibers aramid (Kevlar) txhawb nqa, qhia tias nws ncab tsawg heev. Qhov no ua rau txoj siv sia taug qab thiab kev nruj tsis tu ncua, ua kom ntseeg tau tias kev tsim khoom sai thiab txo qhov xav tau kev saib xyuas.
• Kev Hnav Zoo Tshaj Plaws & Kev Tiv Thaiv Kev Sib Tsoo: Cov qauv fiber ntau ntawm cov koob-punched felt muab kev tiv thaiv zoo heev rau kev sib txhuam los ntawm cov npoo ntse thiab cov khoom hnyav, ua kom muaj kev pabcuam ntev txawm tias nyob hauv kev ua haujlwm tas mus li.
• Kev Ruaj Ntseg Thermal & Kev Coj Hluav Taws Xob: Cov ntaub mos mos ua haujlwm ua ib qho khoom rwb thaiv tsev ntuj, tso cai rau kev tswj hwm cov txheej txheem txias. Nws tiv thaiv kev oxidation ntawm qhov chaw thiab "cov chaw kub" ntawm qhov profile.

Cov Lus Qhia Txog Kev Siv Tshuab Yuav Tsum Xav Txog

Thaum yuav ib txoj siv conveyor felt rau koj txoj kab extrusion, xyuas kom tseeb tias koj txheeb xyuas cov kev ntsuas hauv qab no nrog koj tus neeg muag khoom:

• Dav: Feem ntau yog txij li 20mm txog 3,000mm nyob ntawm qhov loj ntawm cov xovxwm thiab qhov ntev ntawm cov profile.
• Ntev (Circumference): Txawv ntau, txij li 1,780mm txog 25,000mm rau cov kab txheem, nrog rau qee lub tshuab xav tau txog li 40,000mm.
• Thickness: Tus qauv ntau yog 3mm txog 14mm. Rau cov ntawv thov hnyav, kev tsim khoom tshwj xeeb txog li 80mm yog ua tau.
• Qhov Ceev: Ntau ntawm 0.15 txog 0.45 g/cm³; qhov ceev siab dua feem ntau qhia tau tias nws tiv taus kev hnav zoo dua thiab kev teeb tsa compression zoo dua.
• Kev Kho Qhov Chaw: Cov kev xaiv muaj xws li PU (polyurethane) tiav rau qhov chaw du, tiv thaiv kev ua tiav zoo li qub kom tiv thaiv plua plav, thiab kaw ntug kom tiv thaiv kev tawg.
