Dab tsi yog qhov txawv ntawm lub tshuab cua tshuab thiab casting zaj duab xis?**
** Taw qhia
Hauv kev lag luam ntim khoom, muaj ntau txoj hauv kev siv los tsim cov yeeb yaj kiab yas. Ob txoj kev nrov yog tshuab tshuab extrusion thiab cam khwb cia zaj duab xis extrusion. Txawm hais tias ob qho tib si txheej txheem ua rau kev tsim cov yeeb yaj kiab yas, muaj qhov sib txawv me ntsis ntawm cov tshuab cua tshuab thiab cov yeeb yaj kiab casting. Kab lus no yog tsom rau kev tshawb nrhiav thiab sib piv cov yam ntxwv, kev tsim khoom, kev siv, thiab cov khoom ntawm cov yeeb yaj kiab thiab cov yeeb yaj kiab casting.
Blown Film Extrusion
Blown film extrusion yog txheej txheem tsim khoom siv los tsim cov yeeb yaj kiab yas nrog ntau qhov tuab. Cov txheej txheem no suav nrog melting yas resin thiab extruding nws los ntawm lub voj voog tuag. Raws li cov yas molten tawm ntawm qhov tuag, nws yog inflated los ntawm ib tug high-pressure cua system, tsim ib tug npuas-zoo li tus qauv.
Cov yeeb yaj kiab uas tsim los ntawm cov tshuab cua tshuab extrusion muaj cov yam ntxwv tshwj xeeb. Lawv muaj qhov pom tseeb zoo, muaj kev cuam tshuam zoo, siab tsim kua muag lub zog, thiab zoo puncture kuj. Tsis tas li ntawd, cov tshuab cua tshuab muaj qib ntawm stretchability, ua rau lawv haum rau cov ntaub ntawv uas yuav tsum tau elasticity thiab yooj.
Casting Zaj duab xis Extrusion
Casting zaj duab xis extrusion yog lwm txoj hauv kev los tsim cov yeeb yaj kiab yas. Nws cuam tshuam cov yas resin yaj thiab pub nws mus rau hauv lub tiaj tus tuag, uas yog tom qab ntawd txias rau ntawm cov menyuam txias. Cov yas molten kis tusyees thoob plaws cov menyuam qhov chaw, uas ua rau tsim ib zaj duab xis nyias thiab tiaj tus.
Casting films muaj cov khoom sib txawv uas sib txawv ntawm cov yeeb yaj kiab uas tawg. Lawv muaj cov pob tshab zoo heev thiab gloss nto, ua rau lawv tsim nyog rau cov ntawv thov uas qhov tsos tseem ceeb. Casting films kuj muaj superior seem stability thiab uniform thickness faib. Lawv muab cov khoom thaiv zoo dua tiv thaiv ya raws, oxygen, thiab aroma, ua rau lawv zoo tagnrho rau cov khoom ntim khoom puas tsuaj.
Txoj kev tsim khoom
Cov txheej txheem ntawm cov tshuab cua tshuab thiab cov yeeb yaj kiab casting sib txawv, ua rau muaj kev hloov pauv hauv cov khoom thiab cov ntawv thov.
Tshuab zaj duab xis extrusion pib nrog melting ntawm yas resin, ua raws li extrusion los ntawm ib ncig tuag. Cov yas extruded tsim ua npuas, uas yog tom qab ntawd tawg mus rau hauv nteg-flat tubing. Cov raj no txuas ntxiv txiav thiab mob rau hauv yob, hloov mus rau hauv zaj duab xis siv tau. Txoj kab uas hla ntawm qhov tuag, huab cua siab, thiab cov txheej txheem cua txias tuaj yeem cuam tshuam cov thickness thiab lub cev ntawm lub tshuab cua tshuab.
Ntawm qhov tod tes, casting zaj duab xis extrusion cuam tshuam nrog kev pub mis molten yas cob rau hauv lub tiaj tus tuag. Cov resin yog ces txias rau ntawm ib tug chilled roller los tsim ib tug ca zaj duab xis. Cov kev kho mob ntxiv, xws li kev kho mob corona lossis txheej txheej, tuaj yeem siv los txhim kho cov yeeb yaj kiab cov khoom thiab kev ua haujlwm. Qhov ceev ntawm cov menyuam thiab kev tswj qhov kub thiab txias thaum lub sij hawm ua kom txias ua rau muaj kev cuam tshuam rau cov yeeb yaj kiab kawg.
Daim ntawv thov
Vim lawv cov khoom tshwj xeeb, cua tshuab thiab casting zaj duab xis pom cov ntawv thov hauv kev lag luam thiab cov khoom sib txawv.
Blown zaj duab xis yog feem ntau siv nyob rau hauv kev lag luam ntim khoom rau cov khoom xws li hnab, hnab, hnab, thiab shrink wraps. Nws stretchability ua rau nws zoo tagnrho rau cov khoom uas yuav tsum tau wrapping tsis xwm yeem los yog loj. Blown films kuj tseem siv rau hauv kev ua liaj ua teb rau tsev cog khoom zaj duab xis, mulch films, thiab silage npog, muab kev tiv thaiv thiab khaws cia cov qoob loo zoo.
Casting zaj duab xis yog dav siv nyob rau hauv ntim khoom noj, tshwj xeeb tshaj yog rau cov khoom uas yuav tsum tau tshwj xeeb clarity, xws li cov khoom tshiab, khoom noj txom ncauj, thiab confectionery. Cov khoom thaiv zoo tshaj plaws ntawm cov yeeb yaj kiab casting pab ua kom lub neej ntev ntawm cov khoom puas tsuaj. Cov yeeb yaj kiab no kuj tau siv rau hauv kev kho mob rau cov khoom xws li cov ntaub qhwv phais, hnab looj tes, thiab cov ntaub qhwv kom tsis muaj menyuam.
Cov khoom thiab kev sib piv
Txawm hais tias ob qho tib si cua tshuab thiab cov yeeb yaj kiab casting yog cov yeeb yaj kiab yas, lawv muaj cov khoom sib txawv thiab cov yam ntxwv.
Blown films muab kev pom zoo thiab ci ntsa iab, haum rau cov khoom uas qhov pom tseeb yog qhov tseem ceeb. Lawv muaj qhov zoo puncture tsis kam, ua rau lawv tiv taus kua muag thiab punctures. Blown films kuj muaj kev cuam tshuam tshwj xeeb, ua rau lawv ruaj khov thaum thauj thiab tuav.
Casting films, ntawm qhov tod tes, excel nyob rau hauv cov nqe lus ntawm gloss nto thiab tsos, muab ib tug txaus nyiam ntim tov.
