Ukuhlaziywa kwenzuzo yezinto zokubumba i-paper pulp zezitsha zokubumba ezilahlwayo
Izitsha zokudla ezilahlwayo kusukela ngo-1984 eShayina okokuqala ngqa, i-polystyrene (ebhekwa njengezinto eziyinhloko zokusetshenziswa kwezitsha zokudla ze-foam plastic yasakazeka ngokushesha kuwo wonke umuntu ezweni, yaya empilweni yansuku zonke yabantu, yakha imakethe enkulu yabathengi. Ngokwezibalo, iCchina idla izitsha zokudla okusheshayo ezingaba yizigidigidi eziyi-10 minyaka yonke, eziningi zazo izitsha zokudla zepulasitiki ezine-foam ezilahlwayo, kanti izinga lokukhula lonyaka lingamaphesenti angama-25.
Ngenxa yokuthi i-polystyrene ayiboli, kunzima ukuyiphinda isetshenziswe njalo njalo, okuletha ukuphazamiseka okukhulu emsebenzini wokucubungula. Ngemva kweminyaka eminingi yokusebenza kanzima, ubuchwepheshe bokukhiqiza, ubuchwepheshe kanye nemishini yokulahla amathuluzi e-pulp moldino kanye nokudla neziphuzo kuye kwathuthukiswa ngokushesha ezweni lakithi. Izinhlobo eziningi zezitsha zokudla ezidingekayo zokudla okubandayo nokushisayo neziphuzo ezifana nebhokisi lokudla okusheshayo. Amapuleti, amapuleti, izitsha ezinobukhulu obukhulu kakhulu ziye zathuthukiswa: Inqwaba yamapuleti okudla kanye nemifino. Izitolo ezinkulu zase-USA, ekusebenzeni, ziye zakwazi ukuhlangabezana ngokugcwele nemikhuba yokudla yaseShayina, zingagqokwa ngamafutha esobho ashisayo namanzi ngaphandle kokuvuza.
Kusukela ngaleso sikhathi imboni yokubumba ama-pulp kanye namandla ayo okuvikela imvelo ezweni laseShayina, ukukhula okusheshayo nokwanda, kwaqala ukukhula kwezimboni. Njengamanje, ukubumba ama-pulp ephepha okuvela ezitsheni ezinobungani nemvelo!
A, izitsha zokudlala zokonakala kwe-pulp molding
Ngotshani lukakolweni, umoba, umhlanga, utshani kanye nezinye izitshalo zaminyaka yonke ezikhula ngemifino, ngokusebenzisa uhlaka lwe-pulp, ukuhlikihla (noma ukumunca, ukugaya), ukubumba, ukubumba (noma ukubumba), ukukhetha, ukubulala amagciwane, ukupakishwa, njll. Izinto zokusetshenziswa ezisetshenziswayo ziyasetshenziswa kabusha futhi zivuseleleka, futhi akukho manzi amnyama noma amanzi angcolile akhiqizwa ngendlela yokuxuba ngokomzimba.
Izinzuzo zetafula lokubumba i-pulp:
(1) Izinto zokusetshenziswa ziyi-pulp elahliwe noma ukolweni ovuselelekayo, umhlanga, utshani, uqalo, umoba, isundu kanye neminye imicu yotshani. Umthombo ubanzi, intengo iphansi, futhi akukho zinkuni ezisetshenziswayo
(2) Akukho manzi angcolile akhiqizwayo noma akhishwayo enqubweni yokukhiqiza, Izitsha ezinobungani nemvelo ezivela emvelweni
(3) Umkhiqizo awungenwa manzi futhi awungeni mafutha
(4) Ngesikhathi sokusetshenziswa, ingaqandiswa, iqandiswe, ifudumale kuhhavini we-microwave, ingabhaka ama-degrees angu-220
(5) Umkhiqizo ungawohloka ngokuphelele esimweni sawo semvelo zingakapheli izinsuku ezingu-45-90, futhi ungafakwa umquba ekhaya. Ngemva kokuwohloka, ingxenye eyinhloko yizinto eziphilayo ezingeke zikhiqize noma yiziphi izinsalela zikadoti kanye nokungcola.
(6) Njengesitsha sokupakisha, sinezici zokufaka i-bufering, ukumelana nokucindezela kanye nokumelana nokushaqeka okungavikela ngempumelelo imikhiqizo epakishiwe.
(7) Ukupakisha imikhiqizo kagesi ngeke kukhiqize ugesi ongashintshi
