Daim Ntawv Thov thiab Kev Txhim Kho Polypropylene rau Thermoforming hauv Kev Ntim Khoom

1. Cov ntsiab cai yooj yim thiab cov yam ntxwv ntawm thermoforming

Thermoforming yog ib txoj kev ua yas tshwj xeeb los ua cov ntawv thermoplastic rau hauv ntau yam khoom. Cov ntawv thermoplastic raug cua sov kom mos thiab tom qab ntawd nias (lub tshuab nqus tsev lossis lub siab zoo) kom ua rau cov ntawv thermoplastic ua haujlwm rau ntawm qhov chaw ntawm pwm kom tau txais cov duab zoo ib yam li qhov chaw ntawm pwm, thiab tom qab txias thiab ua kom zoo nkauj, cov khoom raug txiav kom tau txais cov duab xav tau. Thermoforming yog ceev thiab sib xws, nrog lub sijhawm luv luv molding thiab tus nqi pwm qis, haum rau automation thiab lub sijhawm tsim khoom ntev, thiab suav hais tias yog txoj kev ua haujlwm zoo tshaj plaws nrog tus nqi qis tshaj plaws ntawm cov txheej txheem molding yas. Tshwj xeeb tshaj yog nrog kev txhim kho tas mus li ntawm cov txheej txheem thermoforming thiab cov khoom siv thiab kev cuam tshuam ntawm kev sim computer, thermoforming tau dhau los ua txoj kev ua haujlwm tseem ceeb sib tw nrog kev txhaj tshuaj thiab tshuab molding. Nyob rau hauv xyoo tas los no, kev nce qib tshiab tau ua nyob rau hauv cov khoom siv thermoforming. Jimin tau qhia txog cov khoom siv thermoforming thiab cov txheej txheem tau nthuav tawm ntawm K2013 hauv lub teb chaws Yelemees, qhov twg qhov ceev, kev hloov pauv tau, kev tswj hwm thev naus laus zis thiab kev txo nqi tau dhau los ua cov ntsiab lus tseem ceeb rau cov khoom siv tshiab rau thermoforming hauv kev ntim khoom thiab kev lag luam.

Cov hom thermoforming tseem ceeb yog: nqus tsev, siab, plunger-assisted forming thiab kev sib xyaw ua ke ntawm lawv. Muaj ntau thiab ntau cov khoom thermoformed hauv kev ua lag luam, xws li khob, phaj, tais zaub mov, cov khoom ua si, lub kaus mom thiab lub kaus mom hlau, cov khoom siv hauv tsev nrog rau cov khoom siv tsheb, cov khoom siv kho kom zoo nkauj, cov khoom siv tshuaj, thiab lwm yam. Piv nrog kev txhaj tshuaj molding, thermoforming muaj qhov zoo ntawm kev ua haujlwm siab, kev nqis peev tsawg hauv cov khoom siv thiab lub peev xwm los tsim cov khoom nrog thaj chaw loj. Cov yas tseem ceeb siv hauv thermoforming yog polystyrene (PS), polyvinyl chloride (PVC), polyolefins xws li PE, PP, polyacrylates (PMMA) thiab cellulose xws li nitrocellulose (NC), cellulose acetate (CA), thiab lwm yam. Cov yas engineering xws liacrylonitrile-butadiene-styrene (ABS)kuj siv tau. Styrene yas (ABS), polycarbonate (PC), thiab lwm yam. Kev tsim cov PP ua tau zoo xws li kev pob tshab siab, lub zog yaj siab thiab qis warpage tau txhawb nqa daim ntawv thov thiab kev txhim kho ntawm PP hauv kev ua thermoforming.

2. Kev Lag Luam Ntim Khoom Thermoforming Hauv Tebchaws

Muaj ntau tshaj 3,000 lub tuam txhab ntim khoom thermoforming hauv tsev, uas ntau tshaj 300 muaj cov khoom tsim tawm txhua xyoo ntau dua 1,000 tons. Kwv yees li 70% ntawm cov chaw tsim khoom uas muaj peev xwm tsim khoom txhua xyoo ntawm ntau txhiab tons yog cov ntawv tsim tawm tus kheej thiab cov neeg koom ua ke ntawm cov khoom thermoformed. PS (OPS) thiab polyethylene terephthalate (PET) yog cov ntawv xa tawm tseem ceeb, thaum qee lub Hoobkas muaj peev xwm tsim lawv cov ntawv PP, PS thiab PVC thiab cov chaw tsim khoom me me xa tawm lawv cov ntawv. Cov khoom thermoformed feem ntau yog siv rau hauv cov khoom ntim khoom noj, cov khoom ntim tsis yog khoom noj thiab cov ntawv txiav, thiab cov kev xav tau rau cov khoom siv raw sib txawv ntawm daim ntawv thov mus rau daim ntawv thov.

3. Kev tsim cov PP rau thermoforming

Cov ntawv thov PP thermoforming hauv tsev tau pib xyoo 1990 thiab tau tsim kho sai sai hauv xyoo tas los no, nrog rau kev loj hlob txhua xyoo ntawm kwv yees li 10%. Tam sim no muaj ntau lub tuam txhab loj thiab nto moo thermoforming yas ntim khoom hauv Suav teb, xws li Nyiv Central Chemical, uas tau tsim cov nroj tsuag hauv Suav teb thiab muab tso rau hauv kev tsim khoom, thiab lawv cov khoom lag luam feem ntau tsom mus rau cov khoom ntim khoom yas nruab nrab thiab siab. Tam sim no, tsis muaj cov ntaub ntawv PP tshwj xeeb rau cov txheej txheem thermoforming hauv Suav teb. Cov chaw tsim khoom thermoforming hauv tsev feem ntau yuav T30S thiab lwm yam khoom siv dav dav hloov kho rau kev siv, tab sis cov khoom tau txais los ntawm kev hloov kho tom qab thiab kev tsim khoom lag luam, muaj kev tswj hwm tsis sib xws, cov khoom tensile tsis ua tau raws li qhov yuav tsum tau ua, cov phab ntsa tsis sib xws hauv thermoforming, extrusion txheej calendering ntug curling thiab lwm yam teeb meem, nws nyuaj rau ua tau raws li qhov zoo thiab siab xav tau ntawm cov kev xav tau ntawm daim ntawv thov, tab sis kuj nyuaj rau ua tau raws li qhov xav tau ntawm qhov zoo thiab siab xav tau, thiab tseem txwv tsis pub ua haujlwm ntau lawm ntawm cov lag luam ua tiav.

Cov ntaub ntawv tshwj xeeb thermoforming txawv teb chaws feem ntau yog homopolymers, cov copolymers pob tshab random tsawg dua, thiab qee qib muaj lub voj voog ntev ntshuam, yog li cov tuam txhab tsim khoom thermoforming hauv tsev tsis tshua siv cov ntaub ntawv ntshuam. Cov ntawv tsim khoom uas twb muaj lawm ntawm cov tuam txhab tsim khoom thermoforming yog feem ntau yog 600 hli dav ntawv, nrog rau kev nce qib ntawm cov tshuab molding, qhov dav ntawm daim ntawv nce ntxiv, qhov dav tshaj plaws tuaj yeem ntau dua 1000 hli, yog li daim ntawv lub peev xwm tiv thaiv kev yaj kom muab cov kev xav tau siab dua. Kev daws teeb meem hauv kev lag luam khoom lag luam downstream yog ntxiv ib feem pua ​​​​​​ntawm cov polyethylene siab (PE-HD) rau PP ib txwm kom txhim kho daim ntawv lub zog yaj, tab sis txoj kev no yuav coj kev sib xyaw tsis sib xws thiab kev pom tseeb tsawg ntawm cov khoom. Kev lag luam thermoforming hauv tsev muaj kev thov ceev ceev rau cov ntaub ntawv raw PP nrog kev ua tau zoo thiab kev pom tseeb siab heev.
Ua ntej xyoo 2012, kev tshawb fawb thiab kev tsim cov khoom siv thermoforming pob tshab siab hauv Suav teb tau poob qis heev. Lub sijhawm ntawd, qhov xwm txheej R & D ntawm cov khoom siv thermoforming tshwj xeeb hauv tsev tau teev nyob rau hauv Rooj 2.

Tsis muaj ib qho ntawm cov ntaub ntawv tshwj xeeb no tau ua haujlwm ntxiv rau qhov muaj zog yaj ntau dua thiab kev faib tawm qhov hnyav molecular dav dua uas xav tau rau kev ua thermoforming, thiab qee qhov tsis tau tsim tawm ntawm qhov loj.

Nyob rau hauv xyoo tas los no, Tianjin Petrochemical tau txuas ntxiv tsim cov ntaub ntawv tshwj xeeb hauv kev ua PP thermoforming, thiab tau txais txiaj ntsig zoo rau kev lag luam thiab kev sib raug zoo, ntxiv xim rau thaj chaw niche no ntawm thermoforming.

Rooj 4 qhia txog cov khoom siv PP tshwj xeeb rau thermoforming tsim los ntawm ntau lub Hoobkas petrochemical hauv xyoo tas los no, uas tau tsim los ntawm Shanghai Ru Xia New Material thiab txhua lub Hoobkas petrochemical rau ntau qhov kev thov hauv ntau qhov sib txawv thermoforming. Cov chaw tsim khoom thermoforming downstream tau faib dav dav, kev lag luam concentration tsawg, muaj ob peb lub tuam txhab saum toj no qhov ntsuas, thiab qhov kev thov rau cov khoom downstream yog ntau yam, thiab cov nroj tsuag petrochemical muaj lawv tus kheej cov phiaj xwm rau kev teem sijhawm ntau lawm, yog li tseem muaj qee qhov teeb meem los sib koom tes zoo nrog upstream thiab downstream, tab sis kev coj ua ntawm kev lag luam thermoforming yog ua cov khoom downstream sib txawv ntawm ib sab tes, thiab siv cov khoom tshwj xeeb rau kev tsim khoom ntawm qhov tod tes, txhawm rau txhim kho cov khoom zoo thiab txhim kho kev ruaj khov ntawm cov khoom zoo. Kev txhim kho thiab kev siv cov khoom tshwj xeeb rau thermoforming tseem muaj kev cia siab.
