Nyob rau hauv lub ntiaj teb niaj hnub no uas muaj kev hloov pauv sai heev, cov hnab yas tau dhau los ua ib feem tseem ceeb ntawm peb lub neej txhua hnub. Txij li kev yuav khoom noj mus rau kev ntim khoom, cov hnab yas no muaj ntau yam kev siv. Txawm li cas los xij, kev tsim cov hnab yas yog ib qho txheej txheem nyuaj uas siv cov tshuab tshwj xeeb hu ua cov tshuab ua hnab yas. Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb cov tshuab no ua haujlwm li cas thiab saib ze dua ntawm cov khoom siv feem ntau siv hauv kev tsim cov hnab yas.
Cov tshuab ua hnab yastau tsim los ua cov hnab yas kom zoo thiab ntau ntau. Cov tshuab no tuaj yeem tsim ntau hom hnab, suav nrog cov hnab tiaj tus, cov hnab gusset, cov hnab tshos, thiab lwm yam. Cov txheej txheem feem ntau muaj ntau kauj ruam tseem ceeb:
1. Cov Khoom Siv Raw: Cov khoom siv tseem ceeb ntawm cov hnab yas yog polyethylene, uas muaj ntau qhov sib txawv, xws li low-density polyethylene (LDPE) thiab high-density polyethylene (HDPE). Lub tshuab ua hnab yas ua ntej pub cov yas resin pellets rau hauv lub extruder.
2. Kev rho tawm: Lub tshuab rho tawm yaj cov yas pellets thiab tsim ib lub raj yas molten tas mus li. Cov txheej txheem no tseem ceeb heev vim nws txiav txim siab qhov tuab thiab qhov zoo ntawm cov khoom kawg.
3. Tshuab Moulding thiab Txias: Yog tias muaj cov yeeb yaj kiab uas raug cua tshuab tawm, cua yuav raug tshuab mus rau hauv lub raj uas yaj kom nws nthuav dav los ua ib zaj yeeb yaj kiab. Tom qab ntawd zaj yeeb yaj kiab yuav raug txias thiab khov thaum nws hla dhau ib pawg ntawm cov menyuam.
4. Kev Txiav thiab Kev Kaw: Tom qab ua tiav zaj duab xis lawm, nws raug txiav kom ntev li qhov xav tau thiab kaw rau hauv qab kom ua ib lub hnab. Cov txheej txheem kaw yuav suav nrog kev kaw cua sov lossis kev kaw ultrasonic, nyob ntawm tus qauv tsim ntawm lub tshuab thiab hom hnab uas raug tsim.
5. Kev Luam Ntawv thiab Kev Ua Tiav: Ntau lub tshuab ua hnab yas muaj cov peev xwm luam ntawv uas tso cai rau cov chaw tsim khoom luam tawm cov logos, cov qauv tsim, lossis cov lus ncaj qha rau ntawm lub hnab. Tom qab luam ntawv, cov hnab raug tshuaj xyuas zoo ua ntej ntim rau kev faib tawm.
Thov saib peb lub tuam txhab cov khoom no,LQ-700 Eco Friendly Yas Hnab Ua Tshuab Hoobkas
Lub tshuab LQ-700 yog lub tshuab kaw lub hnab perforation hauv qab. Lub tshuab muaj ob zaug peb ceg V-fold units, thiab zaj duab xis tuaj yeem quav ib zaug lossis ob zaug. Qhov zoo tshaj plaws yog tias qhov chaw ntawm lub peb ceg quav tuaj yeem hloov kho. Lub tshuab tsim rau kev kaw thiab perforating ua ntej, tom qab ntawd quav thiab rov qab rau hauv qhov kawg. Ob zaug V-folds yuav ua rau zaj duab xis me dua thiab kaw hauv qab.
Cov khoom siv feem ntau siv los ua cov hnab yas yog polyethylene thiab polypropylene. Txhua yam khoom muaj nws cov yam ntxwv tshwj xeeb, ua rau nws haum rau ntau yam kev siv sib txawv.
1. Polyethylene (PE):Qhov no yog cov khoom siv dav tshaj plaws rau cov hnab yas. Nws muaj ob hom tseem ceeb:
- Polyethylene Uas Tsis Tshua Muaj Qhov Ceev (LDPE): LDPE paub txog nws qhov kev ywj pheej thiab mos mos. Nws feem ntau siv los ua cov hnab ntim khoom noj, cov hnab ntim mov ci, thiab lwm yam khoom siv uas tsis hnyav. Cov hnab LDPE tsis ruaj khov npaum li cov hnab HDPE, tab sis nws tiv taus dej noo ntau dua.
- Polyethylene Ceev Siab (HDPE): HDPE muaj zog dua thiab tawv dua LDPE. Feem ntau siv los ua cov hnab tuab dua, xws li cov uas siv hauv cov khw muag khoom. Cov hnab HDPE paub txog lawv txoj kev tiv taus kua muag thiab feem ntau siv los nqa cov khoom hnyav dua.
2. Polypropylene (PP):Polypropylene yog lwm yam khoom siv nrov rau cov hnab yas, tshwj xeeb tshaj yog cov hnab yuav khoom siv rov qab tau. Nws ruaj dua li polyethylene, muaj qhov kub yaj dua, thiab tsim nyog rau cov ntawv thov uas xav tau lub zog thiab tiv taus kub. Cov hnab PP feem ntau siv rau ntim khoom noj vim lawv muab cov khoom thaiv zoo tiv thaiv cov dej noo thiab cov tshuaj lom neeg.
3. Cov yas uas lwj tau:Vim tias tib neeg muaj kev txhawj xeeb ntau ntxiv txog cov teeb meem ib puag ncig, cov yas uas lwj tau los ua neeg nyiam heev nyob rau xyoo tas los no. Cov khoom no lwj sai dua li cov yas ib txwm muaj, txo qhov cuam tshuam rau ib puag ncig. Txawm hais tias cov hnab yas uas lwj tau tseem tsis tshua muaj ntau dua li cov hnab polyethylene thiab polypropylene, tab sis cov neeg siv khoom thiab cov lag luam uas xav txog ib puag ncig tau siv lawv ntau dua.
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 siv sijhawm ntau pua xyoo kom lwj hauv cov chaw pov tseg. Yog li ntawd, ntau lub tebchaws thiab cov nroog tau txwv lossis txwv tsis pub siv cov hnab yas ib zaug xwb, txhawb kom siv cov khoom siv rov qab tau.
Cov chaw tsim khoom siv tshuab ua lub hnab yaskuj tseem tab tom hloov kho rau cov kev hloov pauv no, tsim cov tshuab uas tuaj yeem tsim cov hnab yas uas lwj tau lossis cov hnab ua los ntawm cov khoom siv rov ua dua tshiab. Qhov kev hloov pauv no tsis yog tsuas yog pab txo qhov cuam tshuam rau ib puag ncig ntawm cov hnab yas xwb, tab sis kuj ua tau raws li qhov xav tau ntawm kev ntim khoom ruaj khov.
Cov tshuab ua hnab yas 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 ntaub ntawv siv hauv kev tsim cov hnab yas, xws li polyethylene thiab polypropylene, yog qhov tseem ceeb rau ob tus neeg tsim khoom thiab cov neeg siv khoom. Thaum kev lag luam loj hlob, nws yog qhov tseem ceeb uas yuav tsum xav txog qhov cuam tshuam rau ib puag ncig ntawm kev siv hnab yas thiab tshawb nrhiav lwm txoj hauv kev ruaj khov. 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 twgcov hnab yasraug tsim tawm thiab siv rau hauv txoj hauv kev uas txo qis lawv cov kev cuam tshuam rau lub ntiaj teb.
