Cov khoom siv dab tsi siv rau lub hau khob hauv cov tshuab thermoforming me me?

Cov hau khob pov tseg, zoo li cov uas siv hauv cov khw kas fes, cov khw noj mov ceev ceev, thiab cov khw muag tshuaj yej npuas, muaj nyob txhua qhov chaw hauv peb lub neej txhua hnub. Yog li cov hau no ua li cas? Cov ntaub ntawv tseem ceeb twg siv?

Tsab xov xwm no tsom mus rau peb yam khoom siv rau lub hau uas feem ntau siv—PET, PS, thiab PVC—los pab koj nkag siab txog cov ntsiab lus tshwj xeeb.

Txog Cov Tshuab Thermoforming Me Me

Lub HEY04 Tsis Siv Neeg Lub Tshuab Thermoforming tau tsim los ntawm peb lub chaw haujlwm R & D kom ua tau raws li qhov xav tau ntawm kev lag luam ntim khoom.

Lub Tshuab Thermoforming Me Me muaj cov cua sov vaj huam sib luag, siv hluav taws xob tsawg, me me, thiab kev ua haujlwm pheej yig. Yog li ntawd, nws yog siv dav hauv kev tsim cov hau, npog, tais, phaj, thiab thawv.

Qhov Tseem Ceeb ntawm Kev Xaiv Cov Khoom Siv Zoo:

Kev Ua Haujlwm Zoo: Qhov kub thiab txias ntawm cov khoom siv ncaj qha cuam tshuam rau lub sijhawm ntawm kev tsim khoom.

Qhov Zoo ntawm Khoom: Piv txwv li, lub hau kaw zoo npaum li cas.

Kev Tswj Tus Nqi: Tus nqi khoom siv raw, tus nqi ntawm cov khoom tsim tawm thaum lub sijhawm tsim khoom, thiab kev siv hluav taws xob txhua yam cuam tshuam rau tus nqi kawg.

Tus tsiaj

Kev Pom Tseeb & Kev Ci: PET muaj cov khoom siv kho qhov muag zoo heev, tsim cov hau uas pom tseeb uas ua rau pom cov cim lag luam thiab xim dej haus zoo meej, txhim kho qhov zoo nkauj ntawm cov khoom.

Cov Khoom Uas Thaiv Tau: Muab ib qho kev thaiv zoo tiv thaiv cov pa oxygen thiab carbon dioxide, pab tswj cov fizz hauv cov dej haus uas muaj carbonated thiab tiv thaiv cov ntxhiab tsw phem.

Rau Thermoforming: PET muaj qhov kub thiab txias tshwj xeeb rau kev tsim, yog li kev tswj hwm qhov kub kom meej yog qhov tsim nyog. Ntawm qhov zoo, nws muaj lub zog yaj zoo, txhais tau tias nws poob qis dua thaum lub sijhawm ua kom sov, ua rau cov khoom kawg uas ruaj khov thiab sib xws.

Kev Nyab Xeeb: PET yog suav tias yog cov khoom siv nyab xeeb rau kev sib cuag zaub mov thiab ua tau raws li cov qauv qib zaub mov.

Ib puag ncig zoo: PET yog ib qho ntawm cov yas uas siv tau dua tshiab tshaj plaws.

Daim Ntawv Thov: Siv rau hauv cov dej haus txias xws li cov hau kas fes txias, cov hau tshuaj yej npuas, cov hau khob kua txiv hmab txiv ntoo, thiab cov hau thawv zaub xas lav. Lus Cim: Tus qauv PET feem ntau muaj qhov tiv taus cua sov hauv qab 70 ° C thiab tsis haum rau cov hau dej haus kub tshwj tsis yog tias siv cov PET uas tiv taus cua sov siab (CPET) kho nrog kev siv crystallization tshwj xeeb, txawm hais tias qhov kawg kim dua.

PS

GPPS: Feem ntau siv rau cov hau pob tshab ntawm cov khob mis nyuj yogurt thiab cov thawv khoom qab zib.

HIPS (High Impact Polystyrene): Muab cov roj hmab ntxiv rau hauv GPPS, ua kom lub zog cuam tshuam zoo dua tab sis tsis pom tseeb; feem ntau nws yog dawb lossis dawb tawm.

Rau Thermoforming: PS mos sai sai thaum cua sov thiab kuj teeb tsa sai sai thaum txias, uas pab cov tshuab thermoforming me me ua kom ceev ntau lawm thiab txo kev siv hluav taws xob.

Kev Nyab Xeeb Khoom Noj: Ob qho tib si GPPS thiab HIPS ua raws li FDA cov qauv rau kev ntim khoom noj.

Kev Sib Cav Txog Ib Puag Ncig: PS (tshwj xeeb tshaj yog cov PS uas nthuav dav zoo li cov thawv ua npuas ncauj) ntsib kev tshuaj xyuas ib puag ncig. Nws lwj qeeb heev, thiab nws cov khoom siv rov ua dua tshiab tsis tau tsim dua li PET, ua rau muaj kev txwv lossis txwv tsis pub siv cov khoom PS siv ib zaug xwb hauv ntau thaj chaw.

Cov ntawv thov:

GPPS: Feem ntau siv rau cov hau pob tshab uas xav tau rau cov khob mis nyuj yogurt, cov khob khoom qab zib.

HIPS: Cov khoom siv tseem ceeb rau cov hau dej haus kub (piv txwv li, cov hau kas fes kub, cov hau khob instant noodle). Nws tiv taus cua sov zoo (txog li 90-100 ° C) thiab tus nqi qis ua rau nws yuav luag tsis muaj qhov hloov pauv hauv thaj chaw no.

PVC

Kev Ywj Pheej & Kev Kaw: Cov hau PVC yog mos heev thiab tuaj yeem tsim kom nruj, haum rau ntawm cov npoo khob, tsim kom muaj cua thiab dej kaw zoo uas tiv thaiv kev xau.

Kev Pom Tseeb: Yuav tsim tau nrog kev pom tseeb siab.

Rau Thermoforming: PVC tuaj yeem thermoformed zoo, tab sis kev tswj qhov kub thaum lub sijhawm ua tiav yog qhov tseem ceeb. Kub dhau heev tuaj yeem ua rau lwj, tso cov pa roj corrosive uas ua rau muaj kev phom sij rau tshuab thermoforming me me.

Kev Nyab Xeeb: Qhov no yog qhov tsis zoo tshaj plaws ntawm PVC. Txawm hais tias PVC ntshiab ruaj khov, cov khoom ntxiv xws li cov yas (piv txwv li, phthalates) thiab cov khoom ua kom sov (piv txwv li, cov tshuaj uas muaj cov hlau lead lossis cadmium) siv rau hauv nws cov khoom tuaj yeem ua rau lom. Cov khoom ntxiv no yuav nkag mus rau hauv cov khoom noj uas muaj roj lossis kub. Txawm tias PVC qib zaub mov ua rau muaj kev txhawj xeeb txog kev nyab xeeb ntawm cov neeg siv khoom.

Kev Cuam Tshuam Rau Ib Puag Ncig: PVC feem ntau suav hais tias yog ib qho ntawm cov yas uas tsis zoo rau ib puag ncig. Nws cov khoom tsim tawm thiab lub neej ua haujlwm tuaj yeem tso tawm cov pa phem organic xws li dioxins. Kev hlawv tuaj yeem tsim cov pa roj acidic thiab cov tshuaj lom, thaum kev pov tseg hauv av muaj kev pheej hmoo ntawm kev ntxiv cov tshuaj lom. Kev siv rov qab yog qhov nyuaj tshwj xeeb.

Daim Ntawv Thov: Cov hau rau kas fes txias, tshuaj yej npuas, khob kua txiv hmab txiv ntoo, cov hau thawv zaub xam lav, thiab lwm yam. Txawm li cas los xij, nws siv tsawg zuj zus vim muaj kev txhawj xeeb hais.
