Ungcoliseko lwamagwebu?!

Uninzi lwamagwebu alonakaliswa kwindawo yendalo, lukhokelela kungcoliseko olugqithisileyo. Ngeli xesha ukulahlwa kwegwebu elilahliweyo kuya kuba sisifundo esibaluleke ngakumbi kubo bobabini abavelisi kunye nabaguquleli balo naluphi na ugwebu. Igwebu ngokwendalo lisisixhobo esinomthamo kodwa ezinobunzima obulula, ke zeziphi iindlela ezikhoyo zokulahla amagwebu alahliweyo? Indlela yokusombulula ungcoliseko lwendalo?

Ingaba i-scrap foam ivela phi?

Ukusukela kumhla ekwathi kwenziwa ngawo ibhloko yokuqala yalo naliphi na igwebu laza laguqulwa laba ziinxalenye ezisikiweyo, umbuzo wokuba makwenziwe ntoni na ngesilahlwa esishiyekileyo. ube kwi iingqondo zeengcali zoshishino lwe-foam kunye neengcali.

I-Scrap foam – okanye i-foam offcuts – yimveliso yendalo yenkqubo yokuvelisa i-foam. Ukusebenza kakuhle kwemveliso kuthetha ukuba i-foam converter ijolise ekuveliseni izinto ezininzi kangangoko kunokwenzeka kwibhloko yezinto ezikrwada, ngaloo ndlela inciphisa ubungakanani be-scrap foam. Nangona kunjalo, phantse yonke ibhloko ye-foam eguqulwayo ivelisa ubuncinci ubuncinci bezinto ezikrwada.

Iifoam eziguquguqukayo zaqala ukuveliswa ngexesha leMfazwe Yehlabathi yesiBini ukuze zisetyenziswe njengeengubo zeenqwelo moya. Nangona kunjalo, imveliso yayincinci, kwaye kwaphela ngeminyaka yoo-1950 apho iinkampani ezinkulu zeekhemikhali ezifana neDuPont, BASF kunye neDow Chemicals zaqala ukuvelisa ii-toluene diisocyanate kunye neepolyurethane polyols, ezazifuneka ukuvelisa ubungakanani be-polyurethane foam kunye ne-melamine foam yorhwebo.

Kule minyaka ingama-60 idlulileyo, kuqikelelwa ukuba ngoku kufikelela kwizigidi zeetoni zogwebu oluguquguqukayo. Kodwa laya phi elogwebu? Mhlawumbi okubaluleke ngakumbi kukuba umbuzo ofanayo unokusetyenziselwa i-polyethylene, i-melamine foam, kunye nezinye izinto ezivaliweyo zeeseli, ukuveliswa kwazo okukhokelela kwiitoni zenkcitho kunye ne-scrap minyaka yonke.

Iindlela zokulahla amagwebu alahliweyo

Ukhetho lokulahlwa kogwebu olulahliweyo luxhomekeke ngokupheleleyo kubuninzi kunye nomgangatho wemathiriyeli eveliswayo. Rhoqo, ukutshisa igwebu le-scrap kuthathwa njengendlela emiselweyo yokulahla inkunkuma.

Ugwebu oluthambileyo lunokutshiswa ngokulula, kodwa le nkqubo ivelisa imisi eyityhefu eyingozi kubo bobabini abantu ababandakanyekayo kwinkqubo kunye nokusingqongileyo ngokubanzi. Ezi nkxalabo ziye zakhokelela abavelisi be-foam kunye nabaguquli ukuba bakhangele iindlela ezintsha zokulawula umthamo ophezulu we-foam ye-scrap eyenziwa ngonyaka.

Ngaba ugwebu olulahliweyo lungaphinda lusetyenziswe?

Ukufumana indlela entsha kungcono kakhulu, kwaye ihambelana neminqweno yanamhlanje yokuphinda isetyenziswe zonke izinto ezilahliweyo; kodwa ukuza kuthi ga ngoku, ukusetyenziswa kwe-volumetric kuphela ye-foam ye-scrap i-foam ehlaziyiweyo, eyaziwa ngokuba yi-chipfoam.

Le yinkqubo ye-granulating ye-foam ibe ngamaqhekeza amancinci eemilimitha ezimbalwa ngobukhulu, ukuyidibanisa kwakhona ibe yifom yebhloko enkulu, ethi ke ixinaniswe kwiintlobo ezahlukeneyo zoxinaniso. Izicelo ze-chipfoam ziquka ukupakishwa, i-floor mats, iipaneli zokufunxa isandi, kodwa usetyenziso oluphambili lufana nekhaphethi yangaphantsi.

Abavelisi bekhaphethi zangaphantsi, ngoko ke, baqhutywa yimfuneko yokuba izityalo zabo zifumane amagwebu alahliweyo kangangoko. Ukutyhubela iminyaka, ezi zityalo ziye zaseka iindlela ezisebenzayo zokuqokelela izinto ezilahliweyo kubaguquli be-foam kwihlabathi jikelele kwaye bazithumele kwiifektri zabo ezingaphantsi. Oku kunciphisa kakhulu umthamo wenkunkuma eshiywe ukuba ilahlwe ngezinye iindlela.

Ugwebu olulahliweyo lusathunyelwa kwindawo yokulahla inkunkuma

Nangona inkqubo yokuvelisa i-chipfoam isebenzisa isixa esikhulu sogwebu olulahliweyo, ifuna ngokubanzi imathiriyeli 'enyulu'. Oku kuthetha ukuba ukuba i-foam ifakwe i-laminated kwi-cloth okanye i-tape yokunamathela, ngokuqhelekileyo inikezelwa ngokungenakusebenziseka kwi-carpet underlay.

Imiba efanayo isebenza kwi-foam evaliweyo ye-polyethylene. Kwakhona, ugwebu olulahliweyo luyaqokelelwa kubaguquli luphinde lubuyiselwe kwiplanti yokuvelisa apho igranuliwe. Oku ke kusetyenziselwa ukuvelisa izinto ezifana neemethi zomgangatho kunye neemethi zebala lokudlala. Nangona kunjalo, ugwebu olulahliweyo lwe-polyethylene oluye lwaphantsi kweenkqubo ezongezelelweyo zokuguqulwa alunakuphinda lusetyenzwe kwaye kufuneka lulahlwe kusetyenziswa ezinye iindlela.

Ke, kwenzeka ntoni kulo lonke ugwebu olulahliweyo olungenako ukurisayikilishwa? Kukwakho nothuli lwe-polyurethane, izikhumba zebhloko kunye nezinye iimveliso zenkqubo yokuguqulwa ekufuneka ziqwalaselwe. Siyazi ukuba ukuyitshisa kuyingozi ngoko ke, enyanisweni, indawo yokulahla inkunkuma isekuphela kwendlela eseleyo.

Iintlobo ezimbini zomngundo wase-Ecuadorian i-Pestalotiopsis ziyakwazi ukonakalisa i-bio-degrading polyurethane kwiimeko ze-aerobic kunye ne-anaerobic, ezifana nezo zifumaneka emazantsi eendawo zokulahla inkunkuma. Nangona kunjalo, le nkqubo ithatha amakhulu eminyaka kwaye izifundo ukuza kuthi ga ngoku ayikamiselanga indlela yokukhawulezisa iindlela zokuthotywa.

Yintoni elandelayo kwishishini?

Ixesha elithathwayo ukuba igwebu elilahliweyo lehlise isidima lidala umceli mngeni omkhulu kushishino lwamagwebu nakwabo bathengi banenkathalo ngemekobume yabo. Sibona kwaye sidibana negwebu yonke imihla, kwaye ukuthembela kwethu kwesi sixhobo sisebenza ngeendlela ezininzi kwenza ukuba kungenzeki ukuba amazinga emveliso angacotha nangaliphi na ixesha kungekudala.

I-SINOYQX ikwazile ukwenza uphuhliso oluzinzileyo lokuba yonke i-melamine foam (i-chip okanye i-scrap melamine foam) ingasetyenziswa kurhwebo ukunciphisa ungcoliseko.
