Uhlalutyo oluluncedo lwezitya zokubumba zephepha le-pulp kwiitya zokubumba ezilahlwayo nezibolayo
Izitya zokutya ezilahlwayo ukususela ngo-1984 eTshayina okokuqala ngqa, i-polystyrene (eyeyona nto iphambili kwizixhobo zokutya ezithambileyo ze-foam plasic yasasazeka ngokukhawuleza kuyo yonke indawo yelizwe, yaya kubomi bemihla ngemihla babantu, yakha imakethi enkulu yabathengi. Ngokwezibalo, iCchina itya malunga ne-10 yeebhiliyoni zeebhiliyoni zeempahla zokutya ezikhawulezayo minyaka le, uninzi lwazo ezisetyenziswa kwiplastiki ethambileyo, kwaye izinga lokukhula ngonyaka liyi-25 ekhulwini.
Ngenxa yokuba i-polystyrene ayiboli, kunzima ukuyiphinda isetyenziswe njalo njalo, nto leyo ebangela ingxaki enkulu kumsebenzi wokucubungula. Emva kweminyaka yokusebenza nzima, iteknoloji yemveliso, iteknoloji kunye nezixhobo zezixhobo ze-pulp moldino ezilahliweyo kunye nokutya kunye neziselo ziye zaphuhliswa ngokukhawuleza kwilizwe lethu. Iintlobo ngeentlobo zeetafile ezifunekayo zokutya okubandayo nokushushu kunye neziselo ezifana nebhokisi yokutya okukhawulezayo. Iipleyiti, iipleyiti, izitya ezinobukhulu obuphezulu ziye zaphuhliswa: Iipleyiti ezininzi zokutya kunye neepleyiti zemifuno. Iiflethi zangokuhlwa. njl. iivenkile ezinkulu zase-USA, ekusebenzeni, ziye zakwazi ukuhlangabezana ngokupheleleyo nemikhwa yokutya yaseTshayina, zinokunxitywa ngeoyile yesobho eshushu kunye namanzi ngaphandle kokuvuza.
Ukususela ngoko ishishini lokubumba i-pulp kunye namandla alo okukhusela okusingqongileyo kwilizwe laseTshayina, ukukhula okukhawulezayo nokwanda, ukuya ngasekupheleni kweminyaka yoo-1990 kwaqala ukwanda. Okwangoku, ukubumba i-pulp yephepha evela kwizikhongozeli ezinobuhlobo nokusingqongileyo zendalo!
A, izitya zokuthambisa ezicothayo zokubumba i-pulp
Ngeengca zengqolowa, umoba, ingcongolo, i-streaw kunye nezinye izityalo ze-herbacous zonyaka, i-pulp ngokusebenzisa i-pulp cnushing, grouting (okanye sucking, dredoing), ukubumba, ukubumba (okanye ukubumba), ukukhetha, ukubulala iintsholongwane, ukupakishwa, njl.njl. Izinto ezisetyenzisiweyo ziyaphinda zisetyenziswe kwaye ziyahlaziywa, kwaye akukho manzi amnyama okanye amanzi amdaka aveliswayo ngendlela yokubumba ngokwasemzimbeni.
Iingenelo zetafile zokubumba i-pulp:
(1) Izinto ezisetyenziswayo yi-pulp elahliweyo okanye ingqolowa ehlaziyekayo, ingcongolo, ingca, i-bamboo, umoba, isundu kunye nezinye iintambo zengca. Umthombo ubanzi, ixabiso liphantsi, kwaye akukho mithi isetyenziswayo
(2) Akukho manzi amdaka aveliswayo okanye akhutshwayo kwinkqubo yokuvelisa, Izikhongozeli ezinobuhlobo nokusingqongileyo ezivela kwindalo
(3) Le mveliso ayinamanzi kwaye ayilungelanga ioyile
(4) Kwinkqubo yokusebenzisa, ingakhenkcezwa, ikhenkcezwe, ifudunyezwe yi-oven ye-microwave, ingabhaka kwiidigri ezingama-220
(5) Imveliso inokonakala ngokupheleleyo kwimeko yayo yendalo zingadlulanga iintsuku ezingama-45-90, kwaye ingavundiswa ekhaya. Emva kokubola, eyona nto iphambili yi-organic mater engazukuvelisa inkunkuma kunye nongcoliseko.
(6) Njengesiqulathi sokupakisha, ineempawu zokubhafa, ukumelana noxinzelelo kunye nokumelana noxinzelelo olunokuthi lukhusele iimveliso ezipakishiweyo ngokufanelekileyo.
(7) Ukupakisha iimveliso ze-elektroniki akuyi kuvelisa umbane ongashukumiyo
