Cov ntim khoom yog:
Ib, PE hnab (hnab yas)
Polyethylene hnab, PE hnab, yog tam sim no dav siv cov ntaub ntawv ntim khoom. Feem ntau, nws muaj ob lub hnab ntim qis-PE thiab hnab kub siab-PE. Lub hnab low-density PE muaj ntau dua noo noo permeability thiab huab cua permeability, thiab high-density PE hnab me dua.
Qhov zoo ntawm PE hnab yog kev khwv nyiaj txiag, qis tus nqi, thiab zoo ya raws. Qhov tsis zoo yog tias lawv muaj lub teeb xa hluav taws xob tsis zoo thiab roj tsis kam thiab tsis tuaj yeem siv tsis tau rau ib leeg rau ntim hnab ntim ntim. Nws yog qhov zoo tshaj plaws los siv hnab polyethylene los ntxiv ib txheej ntawm sab nraud ntim uas tuaj yeem tiv thaiv lub teeb thiab muaj huab cua tsis zoo, xws li cov ntawv ntim hluavtaws, cov kaus poom ntim cov hlau, thiab lwm yam .: hnab PE muaj huab cua ntau dua permeability thiab nws nyuaj rau daws cov pa teeb meem hauv lub hnab ntim khoom, uas tsis yog qhov zoo tagnrho Cov khoom ntim.
Thib ob, hlau yaj poom tuaj yeem
Qhov zoo ntawm cov hlau yaj poom yog extrusion tsis kam thiab zoo nkauj. Hauv lub sijhawm thaum ntxov, lawv tau siv rau lub ntim sab nraud ntawm cov hnab ntim cov tshuaj yej nrog lub puab ntim ntawm PE hnab. Txawm li cas los xij, vim yog tus nqi siab thiab yooj yim corrosion thiab deformation, lawv tau maj mam tshem tawm. Cov xim tsis hnov tsw hauv cov xim hlau thiab zawm ntawm lub hau kom zoo tsis txaus siv ib leeg.
Peb, ntawv xov hluavtaws tshuab
Cov ntawv hluavtaws hluavtaws yog tam sim no cov ntaub ntawv ntim khoom siv feem ntau. Nws muaj qhov zoo ntawm kev lag luam, lub teeb ci, thiab kev zoo nkauj. Nws tsuas yog muaj cua siab thiab noo noo permeability, thiab nws tsis haum rau siv ib leeg. Nws yog qhov zoo tshaj plaws los siv PE hnab lossis ntawv nyiaj txhuas ntawv nyiaj lub hnab rau sab hauv ntim. Kab lus no tau pauv los ntawm: West Lake Longjing Cov Ntaub Ntawv Xov Xwm
Plaub, txhuas ntawv nyiaj laminated hnab
Aluminium ntawv ci lub hnab laminated yog qhov zoo nkauj thiab muaj kuab heev. Nws qhov zoo yog opaque, ya raws-pov thawj thiab oxygen-barrier. Nws kim dua PE hnab, thiab nws yuav ua teeb meem extrusion thaum siv ib leeg. Aluminium ntawv ci lub hnab laminated tuaj yeem kho nrog lub tshuab nqus tsev lossis nitrogen lossis deoxidizers. Nrog lub hnab ntim ntawv los yog cov ntawv ntim hluavtaws, lub ntim cov tshuaj yej nplooj tuaj yeem ua tiav los ntawm cov dej noo, roj, lub teeb thiab oxygen. Cia nyob rau hauv qis kub yog qhov zoo tshaj plaws tshuaj yej. Cov qauv zoo meej khaws cia.
Tsib, iav hwj dej, lub rhawv zeb sib nqus, lub thawv ntoo, thawv ntawv ntawv
Txawm hais tias cov iav hwj iav muaj roj zoo heev thiab noo noo tsis kam, lawv yog cov pob tshab, tsis yooj yim, hnyav thiab kim. Lub laujkaub uas muaj hlau nplaum lossis lub ntsej muag khib nyiab tuaj yeem tiv thaiv los ntawm lub teeb tab sis zoo li cov iav huam. Lawv puas yooj yim thiab qhov hnyav. Kev ua tsis tau zoo ntawm lub thawv ntoo tuaj yeem yooj yim ua rau cov tshuaj yej nqus kom ntxaum tsw thiab noo noo thiab ua pa. Lub thawv los yog lub hnab ntawv yooj yim kom nqus noo thiab tawg. Cov ntaub ntawv no tsis zoo tagnrho cov ntim khoom ntim.
Rau, nitrogen filling lossis nqus hnab ntim
Lub tshuab nqus tsev ntim vim yog lub shrinkage ntawm lub hnab ntim khoom. Txhawm rau kom tsis txhob nyem thiab kev sib tsoo thiab rau qhov zoo nkauj, nws yog qhov zoo dua rau kev tiv thaiv sab nrauv ntim khoom. Nitrogen ntim puv tsim yuav nthuav lub hnab, thiab nws yuav tsum tsis txhob nyem kom tsis txhob tawg ntawm lub hnab. Ob qho tib si xav tau ntim ntxiv, thiab kev khaws cia kuj tseem muaj cov txiaj ntsig zoo, tab sis kev nqis peev tau kim dua.
