Kub filling yog cov txheej txheem ntawm sterilizing cov khoom thiab sab hauv lub raj mis los yog thawv thiab hau los yog kaw nyob rau hauv thiaj li yuav ua kom muaj kev ruaj ntseg ntawm cov khoom thiab prolong nws lub txee lub neej. Nws feem ntau yog siv rau lub raj mis uas muaj <4.5pH cov khoom xws li: kua txiv hmab txiv ntoo. Nectars. Kua zaub.
Kuj paub, dab tsi yog txias filling?
Txias Fill . Thaum txias filling , ib lub thawv yog pressurized los ntawm txias cov khoom. Cov txias khoom ntxiv rau a txias thawv. Txias filling yog ib yam rau cov khoom tshiab xws li kua txiv hmab txiv ntoo thiab mis nyuj thiab aerosol daim ntaub ntawv xws li dej qab zib thiab lwm yam dej haus carbonated.
PET lub raj mis puas tuaj yeem ua kom sov? Thaum tshav kub kub PET yog tam sim no ib qho yas thawv hom nyob rau hauv ntau kub puv kev siv dej haus. Lawv tshwj xeeb yog tsim los tiv taus kub - puv qhov kub thiab txias, qee zaum mus txog 192 F, thaum tswj kom pom tseeb thiab lub teeb yuag.
Tsis tas li ntawd, ua li cas koj kub sau cov kua ntses?
Sau jars nrog kub sauce , yam tsawg kawg nkaus puv kub 180 ° F, lub hom phiaj kub yog 200 ° F, teem lub taub hau ntawm ½ thiab npog nrog npaj kaw / hau kom zoo. 2. Hloov lub thawv thiab tuav, 180 ° F lossis siab dua rau 1 feeb lossis ntev dua. Tig lub thawv rau sab thiab cia cua txias.
Dab tsi yog qhov kub thiab txias PET?
Thaum tshav kub kub teeb PET 101 PET yog ib tug semi-crystalline thermoplastic, uas softens ntawm approx. 76 ° C (dab tsi yog hu ua "Glass Transition"). Tshaj qhov ntsuas kub no, cov khoom yuav ua elastic, thiab tuaj yeem tsim tau, cov cuab yeej siv tau zoo hauv cov txheej txheem Stretch Blow Molding.
