Daim ntawv thov thiab kev txhim kho ntawm polypropylene hauv daim ntawv thiab thermoforming ntim khoom

Thermoforming yog ib txoj kev ua yas uas tau tsim kho nyob rau hauv xyoo tas los no.

Nrog kev txhim kho ntawm tib neeg txoj kev ua neej thiab kev hloov pauv hauv kev ua neej, ntau thiab ntau cov khoom thermoformed tshwm sim hauv txhua yam ntawm tib neeg lub neej. Polypropylene (PP) nplooj ntawv muaj cov yam ntxwv ntawm qhov ceev tsawg, tsis muaj tshuaj lom, yooj yim ua, tsis kam warping, thiab zoo dua kub tsis kam. Lawv yog qhov tshwj xeeb tshaj yog rau cov txheej txheem ua xws li thermoforming thiab siv dav hauv cov ntim khoom noj, tsheb, khoom siv hauv tsev thiab lwm yam teb. Tib lub sijhawm, polypropylene tuaj yeem hloov kho ntxiv rau qhov rigidity, pob tshab, qis-kub toughness thiab lwm yam raws li cov kev xav tau kev ua tau zoo ntawm cov neeg siv khoom.

Cov ntsiab cai yooj yim thiab cov yam ntxwv ntawm thermoforming

Thermoforming yog ib txoj kev ua yas tshwj xeeb uas siv los hloov cov ntawv thermoplastic mus rau ntau yam khoom. Tom qab cov ntawv thermoplastic raug cua sov kom nws mos, lub siab (lub tshuab nqus tsev lossis lub siab zoo) yog siv los yuam cov ntawv thermoplastic tawm tsam qhov chaw ntawm cov pwm kom tau txais cov duab zoo ib yam li cov duab. Tom qab txias thiab khov, cov duab xav tau tau txais los ntawm kev txiav. Thermoforming yog ceev thiab sib xws, lub voj voog molding luv luv, tus nqi pwm qis, thiab nws yog qhov tsim nyog rau kev siv tshuab thiab kev tsim khoom ntev. Nws suav hais tias yog txoj kev ua haujlwm pheej yig tshaj plaws thiab ua haujlwm tau zoo tshaj plaws ntawm cov txheej txheem yas molding. Thermoforming tau tsim kho sai sai txij li thaum nws tshwm sim, tshwj xeeb tshaj yog nrog kev txhim kho tas mus li ntawm cov thev naus laus zis thiab cov khoom siv thermoforming thiab kev cuam tshuam ntawm cov txheej txheem simulation hauv computer, thermoforming tau dhau los ua txoj hauv kev ua haujlwm tseem ceeb sib tw nrog kev txhaj tshuaj molding thiab tshuab molding. Nyob rau hauv xyoo tas los no, cov khoom siv thermoforming tau ua tiav tshiab.

Cov hom thermoforming tseem ceeb yog: nqus tsev vacuum forming, pressure forming, plunger-assisted forming thiab lawv cov kev sib xyaw ua ke. Muaj ntau thiab ntau cov khoom thermoformed hauv khw, xws li khob, saucers, tais zaub mov, cov khoom ua si, lub kaus mom hlau, nrog rau cov khoom siv tsheb, 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, thiab lub peev xwm los tsim cov khoom loj dua. Kev tshawb fawb thiab kev txhim kho cov ntaub ntawv polypropylene ua tau zoo xws li kev pom tseeb siab, lub zog yaj siab, thiab qis warpage tau txhawb nqa daim ntawv thov thiab kev txhim kho cov ntawv polypropylene hauv kev ua haujlwm ntawm thermoforming.

Cov teb thov ntawm cov ntawv PP thermoformed

Khoom noj khoom haus ntim

Cov khoom PP thermoformed rau kev ntim khoom noj muaj ntau lub tais xws li lub thawv kaw zaub braised, cov tais nqaij, cov tais tofu, cov thawv noj su pov tseg, thiab lwm yam. Qee cov tais no yog dawb milky, dub, liab, thiab lwm yam, thiab qee cov khoom pob tshab. Tib lub sijhawm, lub hau khob thiab lub hau tais phim cov khoom thermoformed saum toj no kuj tsim los ntawm kev siv ntau ntawm PP pob tshab.

Cov khoom ntim khoom tsis yog khoom noj

feem ntau yog siv rau cov tshuaj ntsiav tshuaj kho mob, cov cuab yeej ntim khoom (cov ntawv sau, cov khoom siv kho vajtse), cov khoom siv hluav taws xob, thiab cov khoom siv ntxuav.

Cov ntawv thiab cov thawv folding

Cov ntawv PP siv dav hauv cov ntawv sau, cov tshuaj pleev ib ce thiab cov khoom ua si tais, cov ntawv ntim khoom qhov rai thiab cov ntawv dai khoom noj khoom haus hauv khw loj. Muaj me ntsis PP pob tshab siv rau hauv cov thawv tais zoo nkauj.

Daim Ntawv PP rau Cov Khoom Noj Thermoformed

● Khob

Cov khob thermoformed feem ntau yog cov khob pov tseg, xws li cov khob tshuaj yej mis nyuj, cov khob dej txias, cov khob zaub mov ceev ceev, thiab lwm yam. Lawv feem ntau yog siv rau hauv cov khw noj mov ceev ceev, cov khw muag tshuaj yej mis nyuj, cov chaw tsim khoom jelly, thiab lwm yam. Cov ntaub ntawv raw feem ntau yog cov ntawv PP pob tshab, thiab qee cov dej haus txias yog ua los ntawm PET.

● Lub thawv noj su uas tiv taus

Cov thawv noj su ib txwm muaj tsuas yog cov khoom noj uas kub qis xwb. Txawm li cas los xij, cov neeg siv khoom kuj yuav tsum khaws cov porridge kub thiab cov kua zaub kub, lossis sterilize lawv hauv qab lub zog kub siab. Cov no tau hais tias muaj qhov yuav tsum tau ua ntau dua rau cov khoom siv raw resin. PET thiab PS tsis tiv taus qhov kub siab. Polypropylene muaj kev tiv taus kub zoo, tus nqi qis thiab yooj yim nrhiav tau, thiab tau dhau los ua cov khoom siv raw nyiam.

● Npog

Cov khoom tseem ceeb suav nrog lub hau tais, lub hau thawv noj su, lub hau khob, thiab lwm yam, uas feem ntau yog siv hauv cov khw noj mov ceev ceev, cov khw muag tshuaj yej mis nyuj, cov khw muag ncuav mog qab zib, thiab lwm yam. Cov hau feem ntau yog pob tshab, thiab cov hau PP feem ntau yog siv rau cov dej haus kub.

● Cov ntaub ntawv hauv cov khoom noj

Cov khoom noj sab hauv feem ntau yog siv rau kev ntim cov ncuav qab zib, cov qos yaj ywm kib, txiv laum huab xeeb thiab lwm yam khoom noj txom ncauj. Yuav muaj ib txheej ntawm cov ntim khoom sab nraud, feem ntau yog siv rau hauv cov chaw tsim khoom noj ceev ceev. Tam sim no, cov khoom noj sab hauv feem ntau yog pob tshab, tab sis kuj dawb mis nyuj. Yuav kom ua rau cov khoom noj ntim puv dua thiab tsis tshua muaj feem yuav raug tsoo, ntau thiab ntau lub tuam txhab ua khoom noj txom ncauj siv cov khoom noj sab hauv.
