Njengamanje, kunesidingo esibalulekile semicamelo enezici ezithuthukisiwe zokukhulula ingcindezi ezenziwe ngezinto zemvelo, ezinye izindlela zamagwebu asekelwe ku-petrochemical.Ukuze sihlangabezane nezidingo, senze imicamelo yegwebu le-latex kusuka ku-deproteinized yemvelo yerabha latex.
Ukulala kubalulekile ukuze kuvuselele impilo yomuntu engokomzimba nengqondo, ngaleyo ndlela kuthinte ngokungaqondile amandla omuntu ngamunye okusebenza.
Izindawo zokulala, okuhlanganisa umatilasi nomcamelo, zidlala indima enkulu ekuthinteni ikhwalithi yokulala.
Ngokusho kwabacwaningi, ukuthuthukisa ikhwalithi yokulala kubalulekile ukunciphisa izenzakalo eziphazamisa ukulala, njengobuhlungu bentamo, ukuhona nokuvuka.Ukulala phezu komcamelo ongayisekeli kahle ikhanda nentamo kungadala ukungezwani kwemisipha yentamo, futhi kubangele ubuhlungu bentamo namahlombe.
Ngakho, ukuthuthukiswa kwemicamelo esekela amalunga ekhanda nentamo ezindaweni ezifanele phakathi nokulala ubusuku bonke kuwukucatshangelwa okubalulekile kubacwaningi nezimboni ngokufanayo.
Imicamelo yekhwalithi ephezulu “yegwebu lenkumbulo” iye yanconywa njengemicamelo yokwelapha enganikeza ikhwalithi yokulala engcono.
Kodwa-ke, imicamelo yegwebu lenkumbulo ibonisa ubude bokuphila obufushane kunamagwebu e-polyurethane avamile.
Kokubili amagwebu enkumbulo kanye namagwebu e-polyurethane avamile enziwa ngamakhemikhali e-petroli, ikakhulukazi ingxube ye-iso-cyanate nama-polyols, kodwa amagwebu enkumbulo ngokuvamile abiza kakhulu kunamagwebu e-polyurethane avamile ngenxa yezithako zamakhemikhali ezengeziwe ezidingekayo ukuze kudluliselwe ukuziphatha kancane kokululama.
Ngokusho kocwaningo lwangaphambilini, ama-isocyanate ayimbangela eyaziwayo yesifuba somoya esibangelwa ukuchayeka okuphezulu, emsebenzini ngesikhathi sokukhiqiza, noma ngokuzwela.
Lokhu kuqwashise abasebenzisi ukuthi kungenzeka ukuthi kokubili igwebu lenkumbulo kanye namagwebu avamile e-polyu-rethane, ngokuhamba kwesikhathi, angakwazi ukukhulula amagesi anobuthi angabangela izingozi empilweni.
Ngaphezu kwalokho, kwaziwa kahle ukuthi izinto zegwebu ezenziwe nge-petrochemical zineqhaza ezindabeni zezempilo nezemvelo kanye nenselelo yokuphathwa kwemfucuza kanye nezinkinga zokulahla.
Ngaphezu kwalokho, ngokuqwashisa okukhulayo mayelana nengozi ekhulayo yokufudumala kwembulunga kanye nokuncipha kukaphethiloli, kanye nomthetho omusha owenziwe ngamazwe amaningana ukukhuthaza ukusetshenziswa "kwezinto eziluhlaza" ekwenzeni umkhiqizo, kokubili. ngesikhathi esifanele futhi kudingekile ukuze kwakhiwe imicamelo engagcini nje ngokunikeza izici zokukhulula ingcindezi kodwa futhi eyenziwe ngezinto ezingenabungozi kangako.
