Eminyakeni yakamuva, ngokuthuthuka okunamandla “komnotho wakhe” kanye nokwanda kokuthengiswa kwe-inthanethi, ithrekhi yezingubo zangaphansi zabesifazane baseShayina iba nezinguquko ezingakaze zibonwe futhi idonse ukunakwa okwengeziwe ngemali enkulu.Ngokusho kwe-iiMedia Research, i-Neihui, i-Oxygen, i-Inman, i-Qingwei, ne-Ubras zonke zithole uxhaso.Ngokwezibalo ezingaphelele, ngo-2018 kuphela, ukutshalwa kwezimali kanye nokuxhaswa ngezimali kwemboni yezingubo zangaphansi yaseChina kudlule ama-yuan ayizigidi ezingama-200.Kusukela ngo-2010, isidingo sabathengi sezingubo zangaphansi eChina siye saqhubeka sikhula: ngo-2010, isidingo sezingubo zangaphansi ezweni lami sasiyizingcezu eziyizigidi eziyizinkulungwane ezingu-6.1 kuphela.Ngo-2019, isidingo sokusetshenziswa kwezingubo zangaphansi zaseChina sizofinyelela izingcezu eziyizigidi eziyizinkulungwane eziyi-16.77, ngesilinganiso sokukhula kwenhlanganisela yonyaka esingu-11.9%.Njengamanje, cishe kunabakhiqizi bezimpahla zangaphansi zasekhaya abacishe babe ngu-10,000, futhi kunemikhiqizo yangaphansi yabesifazane engaphezu kuka-3,000, kodwa ngaphezu kuka-90% wemikhiqizo inesilinganiso sokuthengisa esingaphansi kwama-yuan ayizigidi eziyi-100, futhi ambalwa ama-yuan adlula ibhiliyoni elingu-1.Ngenxa yalesi sizathu, kusukela ekungeneni kwethrekhi, izinhlobo ezihlukahlukene ziye zaqhubeka nokwengeza "ama-gimmicks" emikhiqizweni yazo - manje cishe zonke izinhlobo zezingubo zangaphansi ezingabizwa ngokuthi ama-brand adumile zikhuthaza "umqondo wobuchwepheshe".
Kungakhathaliseki ukuthi isisekelo se-super-elastic memory alloy bra engisithakaselayo ezinsukwini zakuqala, noma “i-super-magic skinny” yendwangu “enwebekayo enezinhlangothi eziyisishiyagalombili” ye-Tingmei, noma i-Ubra edume kakhulu “ayinamkhondo futhi ayinandandatho yensimbi” , i-water drop coaster enelungelo lobunikazi ekhiphekayo, noma ubuchwepheshe be-Banana's Stressfree non-inductive kanye nobuchwepheshe bosekelo lwe-ZeroTouch obungaguquki bugcizelela “umuzwa wobuchwepheshe” wezingubo zangaphansi.Njengengxenye ebalulekile yezingubo zangaphansi zabesifazane, ukugxila kwezinto ezibonakalayo kanye nomsebenzi we-chest pad nakho kubhekene nochungechunge lwezinguquko nemakethe.Namuhla, umbhali uzokuyisa ukuze uqonde izinto ezisetshenziswayo zegwebu emakethe yezingubo zangaphansi zesifuba sabesifazane ngayinye ngayinye.
Izinto ezijwayelekile zephedi esifubeni zifaka igwebu, igwebu lememori, igwebu le-silicone, i-latex, nokotini oqondile we-3D.
isipontshi
Uma kuziwa ezipantshini, into yokuqala efika engqondweni yethu isipontshi sokugeza sokugeza noma isipontshi sokuhlanza izitsha.Lezi zithambile lapho uzithinta, zinezimbobo ezincane endaweni yonke, futhi izinto ziyethusa kancane.Akukhona nje ukuthi imunca kakhulu, kodwa kungakhathaliseki ukuthi "ihlukunyezwa" kanjani, izobuyela esimweni sayo sokuqala ngokushesha nje lapho ikhishwa, futhi ine-plasticity enhle.Kodwa uyazi ukuthini?Izipontshi empeleni ziyisilwane, isilwane sakudala esinamangqamuzana amaningi.Imizimba yawo ayinawo umumo ongaguquki futhi inezimbobo eziningi ezincane ezindongeni zazo.Zihlukaniswa njengezilwane ezinama-porous.Kunezinhlobo eziningi, amashumi ezinkulungwane.Eziningi zazo zimila emanzini aseMedithera, eGulf of Mexico naseBahamas.
Kamuva, ngenxa yokuthuthukiswa kwesayensi yezinto ezibonakalayo kanye nokusetshenziswa kwezinto ze-polymer, manje sesingakwazi ukuthenga kalula imikhiqizo yesiponji eshibhile, ikakhulukazi izipantshi zokwenziwa ezinezinyosi ezinamakhekheba ezinyosi ezenziwe ngama-polymers epulasitiki anegwebu.
Kunezinhlobo eziningi zezipanji zokwenziwa, kodwa ngomqondo omncane, abantu bajwayele ukulinganisa "izipontshi" namagwebu athambile e-polyurethane, akhiwe ngama-polyisocyanates nama-polyols axutshwe namanzi, ama-catalysts kanye nama-stabilizers.Le nto ye-foam eguquguqukayo inokumelana okuhle kwe-oxidation kanye nokumelana ne-solvent, futhi ivame ukusetshenziswa ezindwangu, izindwangu ezihlanganisiwe zezingubo, ukukhiqizwa kwezingubo zangaphansi, njll., kodwa ngenxa yokumelana okungalungile kwe-hydrolysis ye-polyester ngokwayo, impilo yesevisi yegwebu kuleli cala izoba. hhayi isikhathi eside.Indawo eshisayo futhi enomswakama., isenzakalo esiphuzi sizovela ngemva kwesikhathi esithile.
Ngokombono wezithasiselo ekukhiqizeni isipontshi, izizathu zokuphuzi kwesiponji zimi kanje:
Phakathi nenqubo yokukhipha amagwebu/ukucubungula, isipontshi siphenduka sibephuzi ngenxa yokuguga kwe-oxidation eshisayo okubangelwa ukushisa okuphezulu;
Ukufuthwa kwegesi nokubaphuzi ngenxa yokuchayeka kuma-nitrogen oxides (NOx) emoyeni;
Iphuzi ngenxa yokuchayeka kwesipontshi ekukhanyeni kwe-UV.
Ukuze uxazulule inkinga ye-yellowing ye-foam ye-polyurethane eguquguqukayo, abakhiqizi abaningi be-sponge, ikakhulukazi abakhiqizi be-sponge abasezingeni eliphezulu, bazama ukuthuthukisa ukusebenza kwe-sponges ephikisana nokuphuzi ngokufaka ama-antioxidants kanye nokuqiniswa kokukhanya, kodwa umphumela awubonakali..Ngaphezu kwalokho, ngaphezu kokuthambekela ekubeni phuzi nokukhunta, ulwelwesi lwezingubo zangaphansi lwenziwe ngesipontshi, esingakwazi ukungena emanzini okwanele nokungena komoya, futhi sinomphumela wokujuluka obuthakathaka, okulula ukuzalanisa amagciwane.
