Lub hnab siab
Lub hnab ntim siab yog tsim los ntawm cov yas tshiab LDPE yam tsis muaj tshuaj ntxiv. Nws tsis muaj tshuaj dawb, sodium sulfate, barium sulfate, calcium sulfate, thiab lwm yam additives. Yog li nws yog lub hnab tsis muaj xim, tsis muaj ntxhiab tsw nrog lub siab pob tshab, zoo toughness, thiab ib qho kev ntxhib los mos.
Cov khoom no yog dav siv nyob rau hauv lub teeb ntim zaj duab xis rau zaub mov, khoom noj txhua hnub, zaub, thawv hauv ob sab phlu, shrink-wrap, ua liaj ua teb mulch zaj duab xis, tsev xog paj zaj duab xis, thiab cov yeeb yaj duab tshiab.
Cov txiaj ntsig ntawm High Pressure LDPE Bags
- Ntau yam
LDPE hnab siab muaj ntau yam kev siv rau ntau yam kev siv xws li khaws cia thiab thauj khoom noj, ntim cov khaub ncaws, khoom xa tuaj, thiab lwm yam. Muaj nyob rau hauv ntau qhov ntau thiab tsawg, lawv haum rau ob qho khoom loj thiab me thiab tuaj yeem kho nrog cov yam ntxwv zoo li zip-lock kaw, cov qauv luam tawm, lossis cov xim tshwj xeeb kom tau raws li cov kev xav tau sib txawv.
- Durability
LDPE hnab yog ruaj khov, tiv taus kua muag, punctures, thiab abrasions. Qhov no ua rau lawv zoo tagnrho rau khaws cia thiab thauj cov khoom tawg yooj yim lossis cov uas xav tau kev tiv thaiv los ntawm ya raws thiab plua plav. Qee lub hnab LDPE tuaj yeem tiv taus qhov kub thiab txias, txhim kho lawv cov kev siv tau hauv ntau qhov chaw.
- Eco-phooj ywg
Txawm hais tias yog tsim los ntawm LDPE yas, cov hnab no yog ib puag ncig tus phooj ywg vim lawv tuaj yeem siv tau thiab tau txais dav hauv cov chaw rov ua dua tshiab. Lawv tuaj yeem rov siv tau ntau zaus, txo kev cia siab ntawm cov yas siv ib zaug.
- Lub teeb
LDPE hnab yog lub teeb yuag, ntxiv qhov hnyav thiab tus nqi rau cov txheej txheem xa khoom. Lawv muaj txiaj ntsig tshwj xeeb rau cov lag luam koom nrog hauv kev xa khoom.
- Customizable
Cov hnab no tuaj yeem ua raws li cov kev xav tau tshwj xeeb, xws li luam ntawv logo lossis duab, ntxiv zip-lock kaw, tuav, lossis gussets. Qhov kev hloov kho no ua rau lawv tsim nyog rau kev tsim khoom lag luam thiab ua tau raws li cov kev xav tau ntim tshwj xeeb.
- Dej-resistant
LDPE hnab yog dej-tiv taus thiab qee qhov tseem tuaj yeem ua pov thawj, ua rau lawv tsim nyog rau khaws cov khoom tsis zoo xws li khaub ncaws, ntaub ntawv, thiab khoom siv hluav taws xob.
- Rov qab tau
Ntau lub hnab LDPE muaj cov kev xaiv rov qab tau xws li zipper xauv, kom ntseeg tau tias cov khoom khaws cia hauv tuaj yeem nkag tau ntau zaus thaum khaws cov khoom tshiab thiab tiv thaiv kev nchuav lossis xau.
- Yooj yim siv
Poly hnab yog cov neeg siv-phooj ywg, yooj yim qhib thiab kaw, thiab yuav tsum tau siv zog tsawg rau kev thauj khoom thiab khaws cia cov khoom, ua rau lawv yooj yim rau kev siv tus kheej thiab kev lag luam.
Yuav Ua Li Cas LDPE Hnab Yas
1. Cov txheej txheem Blown-Film Extrusion
Thawj kauj ruam hauv kev ua cov hnab poly yog cov txheej txheem cua tshuab extrusion. Nov yog qhov nws ua haujlwm li cas:
- Cov yas me me (hu ua resin) yog yaj nyob rau hauv kev tswj xyuas kom txog thaum lawv ua molten thiab pliable.
- Thaum cov resin ncav cuag qhov xav tau pliability, nws yog extruded los ntawm ib tug voj voog tuag sib txawv los ua ib tug nruam raj ntawm yas. Nyob rau hauv nws lub xeev molten, lub raj yog pinched tawm ntawm ib kawg, ces inflated thiab stretched mus rau qhov loj thiab tuab ntawm cov khoom tiav lawm.
- Lub npuas npuas ntawm cov yas yog kos vertically mus rau ib tug pej thuam kom txias ua ntej nws yuav flattened thiab mob rau ib tug yob.
- Cov yas txias ntawm lub yob tuaj yeem raug txiav mus rau hauv tubing, ib daim kab mob ib leeg, lossis cov ntaub ntawv hauv nruab nrab. Feem ntau, cov yas no ntxiv rau hauv cov hnab poly.
2. Ua Poly Hnab los ntawm cov yob yas
Tom qab cov txheej txheem cua tshuab extrusion, cov yob ntawm cov yas tau hloov mus rau hauv cov hnab poly los ntawm cov kauj ruam hauv qab no:
- Rolls ntawm yas tubing los yog sheeting yog pub los ntawm lub tshuab uas rub cov khoom tawm mus rau qhov ntev.
- Lub tshuab kaw cov khoom ntawm qhov ntev thiab txiav tawm los ua ib lub hnab ntim khoom.
- Cov txheej txheem no rov ua dua kom txog rau thaum tus naj npawb ntawm cov hnab poly rau kev txiav txim raug tsim.
LDPE vs. HDPE hnab
Txawm hais tias HDPE thiab LDPE hnab muaj qee qhov zoo sib xws, qee cov yam ntxwv muab lawv sib cais, feem ntau vim yog cov ceg ntawm cov saw hlau polymer. HDPE muaj cov qauv crystalline ntau dua piv rau LDPE.
- Lub cev sib txawv ntawm LDPE thiab HDPE Hnab
LDPE: Softer thiab hloov tau yooj yim nrog qhov qis melting point ntawm 239 degree F. Nws yog pob tshab dua, tab sis ntau dua rau kev tawg thaum muaj kev ntxhov siab.
HDPE: Muab cov tshuaj tiv thaiv zoo dua, muaj qhov kub siab dua ntawm 275 degree F, thiab tuaj yeem tiv taus qhov kub thiab txias. Nws yog nruj dua, ruaj khov, thiab muaj zog dua thiab opacity vim nws cov qauv crystalline.
- Recycling Qhov txawv
Ob leeg LDPE thiab HDPE tuaj yeem rov ua dua, tab sis lawv tsis tuaj yeem rov ua dua ua ke. LDPE nqa cov khoom siv rov ua dua 4 thiab nws nyuaj rau rov ua dua vim nws cov qauv mos, uas tuaj yeem ntes tau hauv tshuab. HDPE, nrog tus lej 2, tuaj yeem ua tiav yooj yim dua los ntawm cov khoom siv rov ua dua tshiab.
