Wrapping ntawv tais tau maj mam hloov ua npuas ncauj ntim
(1) Pulp molded cov khoom yog ua los ntawm cov nroj tsuag fiber ntau cov ntaub so ntswg los yog cov ntaub ntawv pov tseg uas tuaj yeem rov ua tiav thiab rov siv dua li cov ntaub ntawv yooj yim, thiab tau tsim nrog cov cuab yeej tshwj xeeb thiab tau siv dav hauv cov khoom noj (tshuaj) cia, ntim hluav taws xob, Tsis yog -kev siv tshuab tsis zoo-raws li cov khoom ntsuab hauv kev cog qoob loo, cov khoom siv kho mob, cov khoom siv tes ua.
(2) Nrog rau txoj kev loj hlob ntawm kev lag luam, ntau cov fluorine- muaj cov tshuaj tau nce mus rau hauv cov huab cua, ua rau muaj kev puas tsuaj loj ntawm cov ozone txheej uas tib neeg nyob. Ntau txhiab mais ntawm ozone qhov tau tsim nyob rau hauv Antarctic thiab Arctic, muab lub ntiaj teb ecological ib puag ncig Qhov no ua rau muaj kev puas tsuaj loj. Vim li no, United Nations Environmental Protection Agency tau tsa lub ntiaj teb no -kev sib tham thoob plaws ib puag ncig. Xyoo 1998, "Vienna Convention for the Protection of the Ozone Layer" thiab "Montreal Protocol on Substances that Deplete the Ozone Layer" tau dhau los, qhia meej meej tias cov teb chaws hauv ntiaj teb Nws yuav maj mam txo kom txog thaum cov tshuaj fluorine - muaj cov khoom uas rhuav tshem cov txheej txheem ozone.
(3) Nyob rau hauv xyoo tas los no, cov khoom yas, ib qho ntawm peb cov khoom ntim loj, tshwj xeeb tshaj yog nthuav dav polystyrene (EPS) cov khoom, tau dhau los ua qhov hnyav thiab dhau los ua "dawb paug" uas txhua tus neeg ntxub. Cov pov tseg pov tseg ntawm cov ntim polystyrene ua npuas ncauj ua rau muaj kuab paug rau ib puag ncig. Hlawv ua rau lub ntiaj teb atmospheric ozone txheej; cov pawg tsis tuaj yeem corroded thiab cov qauv geological puas lawm. Cov khoom siv yas ua npuas dej no tau ua rau muaj kev puas tsuaj loj rau lub ntiaj teb ib puag ncig. Hloov mus rau biodegradable ib puag ncig tus phooj ywg ntim cov ntaub ntawv, tshem tawm "dawb paug", thiab kev txhim kho tib neeg lub neej nyob ib puag ncig tau dhau los ua kev xav tau thoob ntiaj teb thiab hauv tsev.
(4) Cov khoom lag luam thiab cov khoom ntim khoom lag luam tsim los ntawm cov tshuab siv tshuab pulp yog cov khoom lag luam zoo ib puag ncig. Lawv siv cov ntoo fibers lossis cov ntawv pov tseg ua cov ntaub ntawv raw, thiab tsis muaj kuab paug hauv kev tsim khoom thiab siv cov txheej txheem. Ntxiv rau nws lub luag haujlwm zoo hauv kev hloov cov khoom siv yas pov tseg, molded pulp khoom kuj tau siv dav hauv ntim cov khoom lag luam, tshwj xeeb tshaj yog cov khoom siv hluav taws xob. Moulded pulp khoom yog maj mam nkag mus rau hauv lub ntsiab ntawm kev lag luam kev ua ub no. Nws yog tam sim no nrov tshaj plaws ua npuas ncauj yas khoom. Lwm cov khoom lag luam zoo, cov khoom siv pulp molded kev lag luam yog booming.
(5) Yog vim li cas vim li cas cov khoom siv pulp molded tau tsim sai thiab muaj kev cia siab zoo yog tias lawv muaj qhov zoo ntawm kev ua tau zoo:
(1) Cov txheej txheem thev naus laus zis yog qhov yooj yim thiab siv tau, thiab tsis muaj kev ua qias tuaj hauv cov txheej txheem tsim khoom, uas ua tau raws li cov kev xav tau ntawm cov khoom siv huv. Tsis tas li ntawd, txhua tus txheej txheem ntawm nws cov kab ntau lawm, tshwj tsis yog tias kev tswj hwm kev tswj hwm tsis siv neeg yuav tsum tau ua haujlwm zoo ntawm cov neeg ua haujlwm, tus so yog tag nrho cov txuj ci thev naus laus zis, uas tuaj yeem ua tiav tom qab luv luv - lub sijhawm kev cob qhia, thiab qib ntawm thaj chaw ntawm nws cov cuab yeej siv siab heev, uas yog qhov zoo heev rau kev ua haujlwm zoo ntawm qhov project. Kev txhawb nqa, uas kuj yog ib qho yooj yim rau kev ceev nrooj ntawm kev tiv thaiv ib puag ncig zoo ntawm cov khoom siv pulp molded.
(2) Ntau qhov chaw ntawm raw khoom thiab tus nqi qis. Nws yog tsuas yog ua los ntawm cov ntawv pov tseg lossis txhua xyoo tshuaj ntsuab fiber ntau. Cov khoom siv raw tuaj yeem hloov kho rau cov xwm txheej hauv zos.
(3) Nws muaj kev poob siab zoo thiab cushioning zog, thiab txoj kev ncua kev kawm yog siv los tsim cov adsorption zoo, uas tuaj yeem tiv thaiv cov khoom tsis zoo thaum lub sijhawm thauj mus los.
(4) Qhov hnyav yog lub teeb, tus nqi rov ua dua yog tsawg, thiab nws tuaj yeem siv rov ua dua.
(5) Kev tiv thaiv zoo, kev sib hloov thiab kev kho kom zoo nkauj.
(6) Los ntawm kev tsim khoom thiab siv rau kev pov tseg pov tseg, tsis muaj kuab paug rau ib puag ncig, kev siv dej hauv cov txheej txheem tsim khoom, tsis muaj dej pov tseg, txo cov pa phem ib puag ncig.
(7) Zoo huab cua permeability, uas muaj qhov tshwj xeeb zoo rau kev ntim khoom tshiab.
(8) Pulp molded cov khoom muaj cov dej zoo nqus, hydrophobicity thiab rwb thaiv tsev kub. Ntau yam additives tuaj yeem muab ntxiv raws li cov neeg siv khoom xav tau thaum lub sijhawm pulping kom cov khoom tiv taus acid, alkali, hnub ci, dej, roj, xau, thiab deformation.
(9) Cov cuab yeej siv niaj hnub no tuaj yeem paub txog siab - ceev, automated loj ntau lawm.
(10) Muab piv nrog cov khoom ntim khoom ib txwm muaj, xws li styrofoam (EPS), EPE ua npuas ncauj, thiab lwm yam, nws muaj qhov ntim me me thiab tuaj yeem ntim thiab khaws cia, txuag chaw cia thiab nqi tsheb thauj mus los.
(11) Raws li cov kev xav tau sib txawv ntawm cov neeg siv, qhov zoo ntawm qhov chaw, xim, duab thiab lwm yam zoo li cov khoom tuaj yeem raug xa tawm - ua tiav kom tau raws li qhov xav tau ntawm cov khoom lag luam.
(6) Vim tias cov khoom lag luam molded muaj cov ntaub ntawv txaus, cov txheej txheem tsim thiab siv yog cov pa phem -dawb, daim ntawv thov dav dav, tus nqi qis, qhov hnyav yog lub teeb, lub zog siab, plasticity, cushioning, interchangeability, kho kom zoo nkauj kev ua tau zoo, thiab nws yuav siv tau ntau zaus nrog cov yam ntxwv ntawm recycling thiab reproduction nws muaj nuj nqis thiab kev siv nyiaj txiag, nws muaj kev vam meej. thiab cov xwm txheej hloov tau raug lees paub los ntawm cov zej zog thoob ntiaj teb.
(7) Raws li daim ntawv thov, pulp molding feem ntau suav nrog ob pawg: pov tseg ib puag ncig tus phooj ywg tableware thiab cov khoom ntim khoom ib puag ncig, ob qho tib si tau siv dav.
