Nyob rau hauv lub ntiaj teb niaj hnub nrawm nrawm, hnab yas tau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub. Los ntawm cov khw muag khoom noj mus rau cov khoom ntim khoom, cov hnab ntau yam no muaj ntau yam siv. Txawm li cas los xij, kev tsim cov hnab yas yog cov txheej txheem nyuaj uas muaj cov tshuab tshwj xeeb hu ua lub hnab yas ua tshuab. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb cov tshuab no ua haujlwm li cas thiab ua tib zoo saib cov ntaub ntawv siv ntau tshaj plaws hauv kev tsim cov hnab yas.
Lub hnab yas ua tshuabyog tsim los tsim cov hnab yas kom zoo thiab muaj ntim ntau. Cov tshuab no tuaj yeem tsim ntau hom hnab, nrog rau lub hnab tiaj tus, hnab gusset, hnab tsho khuam, thiab lwm yam. Cov txheej txheem feem ntau muaj ob peb kauj ruam tseem ceeb:
1. Cov khoom siv raw: Cov khoom siv tseem ceeb ntawm cov hnab yas yog polyethylene, uas muaj qhov sib txawv, xws li low-density polyethylene (LDPE) thiab high-density polyethylene (HDPE). Lub hnab yas ua tshuab ua ntej pub cov yas pellets rau hauv extruder.
2. Extrusion: Lub extruder melts cov yas pellets thiab tsim ib tug nruam raj ntawm molten yas. Cov txheej txheem no tseem ceeb heev vim nws txiav txim siab lub thickness thiab zoo ntawm cov khoom kawg.
3. Tshuab Moulding thiab Cooling: Nyob rau hauv cov ntaub ntawv ntawm cov tshuab cua tshuab extrusion, cua yog tshuab rau hauv lub raj molten kom nthuav nws los ua ib zaj duab xis. Cov zaj duab xis yog ces txias thiab solidified raws li nws dhau los ntawm ib tug series ntawm rollers.
4. Txiav thiab Sealing: Tom qab cov yeeb yaj kiab raug tsim, nws raug txiav mus rau qhov ntev uas yuav tsum tau ua thiab muab khi rau hauv qab los ua ib lub hnab. Cov txheej txheem sealing yuav koom nrog kev sib khi thaum tshav kub kub los yog ultrasonic sealing, nyob ntawm seb lub tshuab tsim thiab hom lub hnab ua.
5.Printing thiab Finishing: Ntau lub hnab yas ua tshuab tau nruab nrog lub peev xwm luam ntawv uas tso cai rau cov tuam txhab luam tawm lub logo, tsim, lossis cov lus ncaj qha rau hauv lub hnab. Tom qab luam ntawv, lub hnab tau txais kev tshuaj xyuas zoo ua ntej muab ntim rau kev faib khoom.

LQ-700 tshuab yog hauv qab sealing perforation hnab tshuab. Tshuab muaj ob zaug daim duab peb sab V-fold units, thiab zaj duab xis tuaj yeem quav ib zaug lossis ob zaug. Qhov zoo tshaj plaws yog tias txoj haujlwm ntawm daim duab peb sab tuaj yeem hloov kho. Tshuab tsim rau sealing thiab perforating ua ntej, ces quav thiab rewinding nyob rau hauv lub xeem. Ob zaug V-folds yuav ua rau zaj duab xis me me thiab hauv qab sealing.
Cov khoom siv feem ntau siv los ua cov hnab yas yog polyethylene thiab polypropylene. Txhua yam khoom muaj nws cov khoom tshwj xeeb, ua rau nws haum rau kev siv sib txawv.
1. Polyethylene (PE):Qhov no yog cov khoom siv dav tshaj plaws rau cov hnab yas. Nws los nyob rau hauv ob lub ntsiab lus:
- Low Density Polyethylene (LDPE): LDPE paub txog nws yooj yim thiab softness. Nws yog feem ntau siv los ua cov hnab ntim khoom noj, hnab cij, thiab lwm yam kev siv lub teeb. LDPE hnab tsis zoo li cov hnab HDPE, tab sis muaj kev tiv thaiv ntau dua rau cov dej noo.
- High Density Polyethylene (HDPE): HDPE muaj zog dua thiab nyuaj dua LDPE. Nws feem ntau yog siv los ua cov hnab tuab, xws li cov khoom siv hauv khw muag khoom. HDPE hnab yog paub txog lawv cov kua muag tsis kam thiab feem ntau siv los nqa cov khoom hnyav dua.
2. Polypropylene (PP):Polypropylene yog lwm yam khoom siv rau cov hnab yas, tshwj xeeb tshaj yog cov hnab ntim khoom siv rov siv dua. Nws yog qhov ruaj khov dua li polyethylene, muaj cov ntsiab lus melting ntau dua, thiab tsim nyog rau cov ntawv thov kom muaj zog thiab kub tsis kam. PP hnab feem ntau yog siv los ntim cov zaub mov vim lawv muab kev tiv thaiv zoo tiv thaiv ya raws thiab tshuaj.
3. Biodegradable plastics:Nrog tib neeg muaj kev txhawj xeeb ntau ntxiv txog teeb meem ib puag ncig, biodegradable plastics tau dhau los ua neeg nyiam nyob rau xyoo tas los no. Cov ntaub ntawv no tawg sai dua li cov yas yas, txo kev cuam tshuam ib puag ncig. Thaum lub hnab biodegradable tseem tsawg dua li cov hnab polyethylene thiab polypropylene, lawv tau txais kev pom zoo los ntawm cov neeg siv khoom thiab cov lag luam.
Kev tsim thiab siv cov hnab yas tau ua rau muaj teeb meem loj rau ib puag ncig. Cov hnab yas ua rau muaj kuab paug thiab tuaj yeem siv ntau pua xyoo kom decompose hauv qhov chaw pov tseg. Yog li ntawd, ntau lub teb chaws thiab lub nroog tau siv cov kev txwv lossis kev txwv rau cov hnab yas siv ib zaug, txhawb kev siv cov khoom siv rov qab siv dua.
Lub hnab yas ua tshuab manufacturerstseem tab tom hloov mus rau cov kev hloov pauv no, tsim cov tshuab uas tuaj yeem tsim cov hnab ntim biodegradable lossis cov hnab ua los ntawm cov khoom siv rov ua dua tshiab. Qhov kev hloov pauv no tsis tsuas yog pab txo qhov cuam tshuam ib puag ncig ntawm cov hnab yas, tab sis kuj ua tau raws li qhov xav tau loj hlob rau cov kev daws teeb meem ntim khoom ruaj khov.
Lub hnab yas ua tshuab ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv feem ntau hauv peb lub neej txhua hnub. Kev nkag siab txog cov khoom siv hauv kev tsim cov hnab yas, xws li polyethylene thiab polypropylene, yog qhov tseem ceeb rau cov tuam txhab thiab cov neeg siv khoom. Raws li kev lag luam loj hlob, nws yog ib qho tseem ceeb uas yuav tau xav txog kev cuam tshuam ib puag ncig ntawm kev siv hnab yas thiab tshawb nrhiav lwm txoj hauv kev ruaj ntseg. Los ntawm kev lees txais kev tsim kho tshiab thiab kev coj ua lub luag haujlwm, peb tuaj yeem ua haujlwm rau yav tom ntej qhov twghnab yasyog tsim thiab siv nyob rau hauv ib txoj kev uas minimizes lawv cuam tshuam rau lub ntiaj chaw.
