Cov tais ntawv tuaj yeem muab faib ua peb pawg: cov ntawv ntim khoom, cov tais ntawv ua liaj ua teb thiab cov tais zaub mov.
1. Muaj cov ntawv tais: Feem ntau yog siv rau hauv cov hnab ntim khoom siv hauv tsev, khoom siv kho mob, cov khoom siv hluav taws xob, thiab teeb pom kev zoo.
2. Kev them nyiaj yug daim ntawv ua liaj ua teb: feem ntau yog siv rau txiv hmab txiv ntoo, nqaij qaib qe, ua liaj ua teb tais diav, thiab lwm yam.
3. Cov ntawv tais zaub mov: feem ntau yog siv hauv cov tais zaub mov, lauj kaub, tais zaub mov hauv tsev loj, thiab lwm yam.
(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 yog tsim los ntawm cov cuab yeej siv tshwj xeeb thiab tau siv dav hauv cov khoom noj (tshuaj) cia, ntim hluav taws xob, Tsis yog- 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 kilometers ntawm ozone qhov tau tsim nyob rau hauv Antarctic thiab Arctic, muab lub ntiaj teb ecological ib puag ncig ua rau muaj kev puas tsuaj loj. Vim li no, United Nations Environmental Protection Agency tau teeb tsa lub rooj sib tham thoob ntiaj teb 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 fluorine- muaj cov tshuaj 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 tsis zoo ntawm ntau yam, thiab tau 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. combustion rhuav tshem lub ntiaj teb atmospheric ozone txheej; pawg tsis tuaj yeem corroded, ua rau kev puas tsuaj rau cov qauv geological. 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, kev lag luam pulp molded khoom lag luam yog booming.
(5) Pulp molded cov khoom tau tsim sai thiab muaj kev cia siab zoo vim tias lawv qhov kev ua tau zoo tshwj xeeb:
(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. Txoj kev ncua kev tshem tawm ua rau zoo heev adsorption, uas tuaj yeem tiv thaiv cov khoom ntawm kev puas tsuaj thaum thauj.
(4) Lub teeb yuag, tus nqi qis dua, thiab 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 pov tseg pov tseg, nws tsis ua paug ib puag ncig, siv dej tsawg dua hauv cov txheej txheem tsim khoom, thiab tsis muaj dej pov tseg, uas 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) Txij li cov khoom lag luam molded muaj cov khoom siv raw khoom txaus, kev tsim khoom thiab siv cov txheej txheem yog cov pa phem -dawb, Scope ntawm daim ntawv thov yog dav, tus nqi qis, qhov hnyav yog lub teeb, lub zog yog zoo, lub 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 txoj kev loj hlob thiab kev loj hlob ntawm kev lag luam, thiab nws cov kev siv tau zoo, tus nqi 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.
