Cov pob khov nab kuab, raws li qhov qis - qhov nruab nrab qhov kub thiab txias tau siv dav hauv kev kho mob tub yees, kev txuag zaub mov, thiab kev thauj mus los txias, muaj lawv cov txheej txheem molding ncaj qha cuam tshuam rau cov khoom lag luam, ua haujlwm ntev, thiab kev nyab xeeb. Nrog rau kev nce qib hauv cov ntaub ntawv tshawb fawb thiab kev tsim khoom siv tshuab, cov txheej txheem ntim dej khov molding tau ua kom zoo ntxiv kom ua tau raws li qhov qis - qhov kub thiab txias ntawm ntau yam xwm txheej. Kab lus no hais txog kev sib tham txog cov dej khov pob molding tshuab los ntawm cov khoom xws li xaiv cov khoom, molding txoj kev, cov txheej txheem tseem ceeb, thiab kev lag luam kev loj hlob tiam sis.
Kev xaiv thiab yam ntxwv ntawm cov khoom siv khov nab kuab
Cov ntaub ntawv tseem ceeb ntawm lub pob dej khov feem ntau muaj cov yeeb yaj kiab sab nrauv thiab cov neeg ua haujlwm txias cia sab hauv. Cov khoom siv sab nrauv yuav tsum muaj qhov zoo qis -kub tsis kam, tsim kua muag, thiab tshuaj lom neeg ruaj khov. Cov kev xaiv feem ntau suav nrog polyethylene (PE), polypropylene (PP), lossis cov yeeb yaj kiab sib xyaw. Ntawm cov no, PE zaj duab xis yog hloov tau yooj yim thiab tsim nyog rau cov pa qis - qhov kub thiab txias; thaum PP cov khoom muaj kev kub ntxhov siab dua thiab tsim nyog rau cov xwm txheej uas yuav tsum tau siv dua.
Tus neeg sawv cev hauv qhov txias txias yog qhov tseem ceeb rau kev tswj xyuas qhov kub thiab txias ntawm lub pob dej khov. Kev lig kev cai, gel- xeev cov polymers (xws li sodium polyacrylate) los yog inorganic ntsev tov (xws li ammonium nitrate) feem ntau yog siv. Nyob rau hauv xyoo tas los no, bio-raws li cov ntaub ntawv hloov pauv theem (PCMs) tau txais kev saib xyuas ntau ntxiv vim lawv qhov kev nyab xeeb ib puag ncig thiab tswj tau theem hloov kub. Cov ntaub ntawv no tau dhau los ntawm cov khoom siv- cov kua theem hloov ntawm qhov kub thiab txias, nqus los yog tso tawm ntau cov cua sov kom ua tiav qhov ntsuas kub.
Cov txheej txheem tseem ceeb Moulding rau Ice Packs
1. Kub Compression Moulding
Kub compression molding yog ib qho ntawm cov txheej txheem ntau tshaj plaws hauv kev ntim khoom khov. Nws lub hauv paus ntsiab lus yog ua kom cov khoom siv ua yeeb yaj kiab los ntawm cua sov, tom qab ntawd siv lub zog hauv pwm los tsim thiab kaw nws. Cov txheej txheem no yog tsim rau loj- nplai ntau lawm, muaj txiaj ntsig zoo, thiab muaj nqi tsawg. Cov tsis tseem ceeb rau kev kub compression molding muaj xws li cua sov (feem ntau yog 120-180 degree), siab (5-20 MPa), thiab tuav lub sij hawm (5-30 vib nas this), uas yuav tsum tau kho kom raug raws li cov khoom siv kom tsis txhob muaj ntau shrinkage los yog sealing tsis zoo.
2. Txhaj Moulding
Rau cov pob khov nab kuab uas muaj cov txheej txheem nyuaj (xws li kev tsim nrog cov khoom siv los yog cov hlua ntxiv), kev txhaj tshuaj molding yog qhov zoo dua. Cov txheej txheem no suav nrog kev txhaj tshuaj molten yas rau hauv pwm precision thiab ceev ceev txias thiab solidifying nws nyob rau hauv siab. Kev txhaj tshuaj- cov pob khov nab kuab feem ntau muaj lub zog siv tshuab ntau dua, tab sis xav tau cov cuab yeej siv loj dua thiab tsim nyog rau tus nqi siab - ntxiv cov khoom.
3. Tshuab Moulding thiab Hollow Structure Design
Qee cov pob khov nab kuab siv tshuab moulding los tsim cov qauv hollow, ua kom lub peev xwm ntawm cov tub yees thiab ua kom zoo dua rwb thaiv tsev. Tshuab moulding yuav tsum tau txhaj cov cua compressed rau hauv cov yeeb yaj kiab tubular, ua rau nws nthuav dav thiab ua raws li cov phab ntsa sab hauv ntawm pwm, thaum kawg tsim lub thawv hnyav thiab ruaj khov. Cov txheej txheem no feem ntau yog siv rau cov pob khov nab kuab loj lossis kev lag luam - qib ntim khoom txias.
Cov txheej txheem tseem ceeb Parameter thiab Kev Tswj Xyuas Zoo
Lub molding zoo ntawm cov ice packs yog cuam tshuam los ntawm ntau yam, nrog rau cov khoom thickness, sealing lub zog, thiab cov uniformity ntawm refrigerant faib. Piv txwv li, ib zaj duab xis nyias nyias yuav ua rau qis -kub brittleness, thaum lub foob tsis zoo tuaj yeem ua rau txias txias. Cov txheej txheem tsim khoom niaj hnub no feem ntau suav nrog kev ntsuas kev siv tshuab thev naus laus zis, xws li infrared thermal imaging lossis kev sim siab lwj, kom ntseeg tau tias muaj kev ntseeg siab ntawm txhua pawg ntawm cov khoom.
Tsis tas li ntawd, ib puag ncig yuav tsum tau tsav txoj kev loj hlob ntawm cov khoom ntim khoom khov rau cov khoom siv biodegradable. Qee lub tuam txhab siv cov hmoov txhuv nplej siab -raws li los yog PLA (polylactic acid) cov yeeb yaj kiab, ua ke nrog cov kuab tshuaj -dawb nplaum thev naus laus zis, txhawm rau txo kev cuam tshuam ib puag ncig.
Kev Tsim Kho Kev Lag Luam
Nyob rau hauv lub neej yav tom ntej, ice pack molding txheej txheem yuav hloov mus rau ntau dua efficiency, txawj ntse, thiab sustainability. Ntawm qhov tod tes, 3D tshuab luam ntawv tuaj yeem siv rau kev tsim cov pob khoom khov kho kom tau raws li cov qauv tshwj xeeb; Ntawm qhov tod tes, kev qhia txog cov ntaub ntawv nanocomposite yuav tsum txhim kho cov thermal rwb thaiv tsev thiab cov khoom siv dag zog ntawm cov pob khov nab kuab. Lub caij no, lub tswv yim kev lag luam ncig yog ua rau cov tuam txhab tsim cov khoom ntim dej khov rov qab, ntxiv txo cov nqi siv thiab kev siv peev txheej.
Optimizing ice pack molding txheej txheem tsis tsuas yog tso siab rau kev ua tiav hauv cov ntaub ntawv tshawb fawb tab sis kuj yuav tsum muaj kev sib koom ua ke ntawm kev tsim khoom thiab kev tswj xyuas zoo. Nrog rau qhov kev thov ntau ntxiv rau cov khoom siv txias txias, cov kev daws teeb meem zoo thiab ib puag ncig tus phooj ywg yuav dhau los ua qhov tseem ceeb ntawm kev txhim kho kev lag luam.
