Ukungcola Kwegwebu?!

Amagwebu amaningi awonakele endaweni engokwemvelo, okuholela ekungcoleni okukhulu. Phakathi naleso sikhathi ukulahlwa kwegwebu elilahliwe kuba yindaba ebaluleke kakhulu kubo bobabili abakhiqizi nabaguquli banoma yiliphi igwebu. Igwebu ngokwemvelo liyi-volumetric kodwa enesisindo esincane, ngakho yiziphi izindlela ezikhona zokulahla igwebu elilahliwe? Ungakuxazulula kanjani ukungcola kokwasekuqaleni?

I-scrap foam ivelaphi?

Kusukela ngosuku okwakwenziwa ngalo ibhulokhi lokuqala lanoma yiliphi igwebu laguqulwa laba izingxenye ezisikiwe, umbuzo wokuthi yini okufanele yenziwe nge-scrap esele kwaba ku izingqondo zochwepheshe bemboni yegwebu kanye nezingcweti.

I-Scrap foam – noma i-foam offcuts – iwumkhiqizo wemvelo wenqubo yokukhiqiza i-foam. Ukusebenza kahle kokukhiqiza kusho ukuthi i-foam converter ihlose ukukhiqiza izingxenye eziningi ngangokunokwenzeka kusuka kubhulokhi yezinto zokusetshenziswa, ngaleyo ndlela inciphise inani le-scrap foam. Noma kunjalo, cishe yonke ibhulokhi ye-foam eguqulwayo ikhiqiza okungenani inani elincane lezinto zokusetshenziswa.

Ama-foam aguquguqukayo aqale athuthukiswa ngesikhathi seMpi Yezwe II ukuze asetshenziswe njengezingubo zezindiza. Kodwa-ke, ukukhiqizwa kwakuncane, futhi kwaze kwaba ngawo-1950 lapho izinkampani ezinkulu zamakhemikhali ezifana neDuPont, BASF kanye neDow Chemicals zaqala khona ukuthuthukisa ama-toluene diisocyanate kanye nama-polyurethane polyol, okwakudingeka ukuze kukhiqizwe amavolumu e-polyurethane foam kanye ne-melamine foam athengiswayo.

Phakathi neminyaka engu-60 edlule, kulinganiselwa ukuthi lokhu manje sekuhlanganisa izigidi zamathani egwebu eligobekayo. Kodwa lishonephi lelogwebu? Mhlawumbe okudabukisayo nakakhulu ukuthi umbuzo ofanayo ungasetshenziswa ku-polyethylene, igwebu le-melamine, nezinye izinto zamaseli avaliwe, ukukhiqizwa kwawo okuholela emathani okumosha nokulahlwa minyaka yonke.

Izindlela zokulahla amagwebu alahliwe

Izinketho zokulahlwa kwegwebu elilahliwe zincike ngokuphelele ekumineni nakwikhwalithi yezinto ezikhiqizwayo. Ngokuvamile, igwebu elivuthayo elivuthayo lithathwa njengendlela ezenzakalelayo yokususa udoti.

Igwebu eliguquguqukayo lingashiswa kalula nje, kodwa le nqubo ikhiqiza intuthu enobuthi eyingozi kubo bobabili abahililekile kule nqubo kanye nemvelo iyonke. Lokhu kukhathazeka kuholele ekutheni abakhiqizi begwebu nabaguquli bafune izindlela ezintsha zokuphatha umthamo omkhulu wegwebu elilahliwe elikhiqizwa unyaka nonyaka.

Ingabe igwebu elilahliwe lingagaywa kabusha?

Ukuthola indlela entsha kungcono kakhulu, futhi kuhambisana nezifiso zanamuhla zokugaywa kabusha kwazo zonke izinto ezilahliwe; kodwa kuze kube manje, ukusetshenziswa kwe-volumetric kuphela kwegwebu le-scrap yi-foam ehlanganisiwe, eyaziwa ngokuthi i-chipfoam.

Lena ngokuyisisekelo inqubo ye-granulating foam ibe izingcezu ezincane zamamilimitha ambalwa ngosayizi, iphinde ihlanganiswe ibe ifomu elikhulu lebhulokhi, elibese licindezelwa ekuminyaniseni okuhlukahlukene. Izicelo ze-chipfoam zifaka ukupakishwa, omata baphansi, amaphaneli okumunca umsindo, kodwa ukusetshenziswa okuyinhloko kufana ne-carpet underlay.

Ngakho-ke, abakhiqizi be-carpet underlay baqhutshwa isidingo sezitshalo zabo ukuze bathole igwebu eliningi ngangokunokwenzeka. Ngokuhamba kweminyaka, lezi zitshalo ziye zasungula izindlela eziphumelelayo zokuqoqa izinto ezilahliwe eziguqulini zegwebu emhlabeni wonke futhi zizibuyisele ezimbonini zazo ezingaphansi. Lokhu kunciphisa kakhulu umthamo wezinhlamvu ezishiywe ukuze zilahlwe ngezinye izindlela.

Igwebu elilahliwe lisathunyelwa endaweni yokulahla udoti

Nakuba inqubo yokukhiqiza i-chipfoam isebenzisa inani elikhulu legwebu elilahliwe, ngokuvamile idinga izinto 'eziyintombi'. Lokhu kusho ukuthi uma i-foam ifakwe i-laminated kwindwangu noma i-adhesive tape, ngokuvamile inikezwa engasetshenziswanga ekufakweni kwekhaphethi.

Izinkinga ezifanayo zisebenza kugwebu le-polyethylene elivaliwe. Futhi, igwebu elilahliwe liyaqoqwa kuma-converctor futhi libuyiselwe endaweni yokukhiqiza lapho likhishwa khona. Lokhu-ke kusetshenziselwa ukukhiqiza izinto ezinjengamata aphansi kanye nomata benkundla yokudlala. Kodwa-ke, igwebu le-polyethylene elilahliwe elifakwe ezinqubweni ezengeziwe zokuguqulwa alikwazi ukucutshungulwa futhi kufanele futhi ilahlwe kusetshenziswa ezinye izindlela.

Ngakho-ke, kwenzekani kuwo wonke amagwebu alahliwe angakwazi ukugaywa kabusha? Kukhona futhi uthuli lwe-polyurethane, izikhumba ze-block kanye neminye imikhiqizo yenqubo yokuguqula okufanele icatshangelwe. Siyazi ukuthi ukuyishisa kuyingozi ngakho, empeleni, indawo yokulahla imfucumfucu kusewukuphela kwendlela esele.

Izinhlobo ezimbili zesikhunta sase-Ecuadorian i-Pestalotiopsis ziyakwazi ukucekela phansi i-polyurethane nge-bio-degrading ezimweni ze-aerobic kanye ne-anaerobic, njengalezo ezitholakala ngaphansi kwezindawo zokulahla imfucumfucu. Kodwa-ke, le nqubo ithatha amakhulu eminyaka futhi izifundo kuze kube manje azikanqumanga ukuthi zingasheshisa kanjani izindlela zokwehlisa isithunzi.

Yini elandelayo embonini?

Isikhathi esisithathayo ukuthi igwebu elilahliwe lehlise isithunzi sidala inselelo enkulu embonini yegwebu kanye nakulabo bathengi abakhathalela imvelo yabo. Sibona futhi sibhekana negwebu nsuku zonke, futhi ukuthembela kwethu kule nto esebenza ngezindlela ezihlukahlukene kakhulu kwenza kungenzeki ukuthi amanani okukhiqiza azokwehla noma nini maduze.

I-SINOYQX ikwazile ukwenza intuthuko eqhubekayo yokuthi yonke i-melamine foam (i-chip noma i-scrap melamine foam) ingasetshenziswa kwezentengiselwano ukunciphisa ukungcola.
