Guhanga udushya mu nganda zifuro |Mubihe byubukungu bwe, tekinoloji iha imbaraga isoko yimbere, reba uburyo ibikoresho byinshi bishobora gusoma imitima yabagore

Mu myaka yashize, hamwe n’iterambere rikomeye ry’ubukungu bwe ndetse n’izamuka ry’ibicuruzwa byo kuri interineti, inzira y’imyenda y’abagore y’abashinwa irimo guhinduka mu buryo butigeze bubaho kandi ikaba yarakunzwe cyane n’umurwa mukuru.Nk’uko ubushakashatsi bwa iiMedia bubitangaza, Neihui, Oxygen, Inman, Qingwei, na Ubras bose babonye inkunga.Nk’uko imibare ituzuye, mu 2018 honyine, ishoramari n’inkunga by’inganda z’imbere mu Bushinwa zirenga miliyoni 200.Kuva mu mwaka wa 2010, abaguzi bakeneye imyenda y'imbere mu Bushinwa bakomeje kwiyongera: mu 2010, icyifuzo cy'imyenda y'imbere mu gihugu cyanjye cyari miliyari 6.1 gusa.Kugeza mu mwaka wa 2019, Ubushinwa bukoresha imyenda y'imbere buzagera kuri miliyari 16.77, aho impuzandengo ya buri mwaka izamuka rya 11.9%.Kugeza ubu, hari abakora imyenda y'imbere mu gihugu bagera ku 10,000, kandi hariho ibirango by'imbere by'abagore barenga 3.000, ariko hejuru ya 90% by'ibicuruzwa bifite igurishwa ritageze kuri miliyoni 100, naho ibicuruzwa bike birenga miliyari imwe.Kubera iyo mpamvu, kuva yinjira mumurongo, ibirango bitandukanye byakomeje kongeramo "gimmicks" kubicuruzwa byabo - ubu ibirango by'imyenda y'imbere hafi ya byose bishobora kwitwa ibirango bizwi biteza imbere "imyumvire y'ikoranabuhanga".

Yaba super-elastique yibuka alloy bra base nashimye muminsi yambere, cyangwa "super-magic skinny" yimyenda ya Tingmei "imyenda ya elastike umunani", cyangwa Ubras izwi cyane "nta kimenyetso kandi nta mpeta y'icyuma" , gutandukana kwamazi yatonywe mumazi, cyangwa Stressfree ya Banana ya tekinoroji idahwitse hamwe na tekinoroji ya ZeroTouch idahwitse bashimangira "imyumvire yikoranabuhanga" yimyenda y'imbere.Nkigice cyingenzi cyimyenda yimbere yabategarugori, kwibanda kubintu nibikorwa byigituza cyigituza nabyo bigenda bihinduka hamwe nisoko.Uyu munsi, umwanditsi azagutwara kugirango usobanukirwe nibikoresho byifuro mumasoko yimbere yimbere yabagore isoko yigituza umwe umwe.

Ibikoresho bisanzwe byo mu gatuza birimo ifuro, ububiko bwa memoire, silicone ifuro, latex, na pamba ya 3D igororotse.

sponge

Ku bijyanye na sponges, ikintu cya mbere kiza mubitekerezo byacu ni sponge yo kwiyuhagira yo koga cyangwa sponge yoza yoza amasahani.Ibi byoroshye gukoraho, hamwe nu mwobo muto hejuru yubuso, kandi ibintu biteye ubwoba buke.Ntabwo ikurura cyane, ariko niyo yaba “yahohotewe” gute, izasubira uko yari imeze ikimara kurekurwa, kandi ifite plastike nziza.Ariko uzi iki?Sponges mubyukuri ninyamaswa, inyamanswa yibanze cyane.Imibiri yabo ntigifite imiterere ihamye kandi ifite imyobo mito mito murukuta rwabo.Bashyizwe mu nyamaswa zangiza.Hariho ubwoko bwinshi, ibihumbi mirongo.Benshi muribo bakurira mumazi ya Mediterane, Ikigobe cya Mexico na Bahamas.

Nyuma, kubera iterambere ryubumenyi bwibikoresho no gukoresha ibikoresho bya polymer, ubu dushobora kugura byoroshye ibicuruzwa bya sponge bihendutse, cyane cyane sponges ya synthique hamwe nubuki bwubuki bukozwe muri polimeri ya pulasitike ifuro.

Hariho ubwoko bwinshi bwa spongique, ariko muburyo buke, abantu bamenyereye kugereranya "sponges" nifuro yoroshye ya polyurethane isanzwe, igizwe na polyisocyanates na polyoli ivanze namazi, catalizator na stabilisateur.Ibikoresho byoroshye byoroshye bifite imbaraga zo kurwanya okiside no kurwanya ibishishwa, kandi bikunze gukoreshwa mubudodo, imyenda ikomatanya imyenda, gukora imyenda y'imbere, nibindi, ariko kubera hydrolysis idahwitse ya polyester ubwayo, ubuzima bwa serivisi bwifuro muriki kibazo bizabikora si birebire.Ibidukikije bishyushye kandi bitose., umuhondo phenomenon izagaragara nyuma yigihe runaka.

Ukurikije inyongeramusaruro mu musaruro wa sponge, impamvu zitera umuhondo wa sponge nizi zikurikira:

Mugihe cyo kubira ifuro / gutunganya, sponge ihinduka umuhondo kubera gusaza kwa okiside yumuriro biterwa nubushyuhe bwinshi;
Umwuka wa gazi n'umuhondo kubera guhura na aside ya azote (NOx) mu kirere;
Umuhondo kubera kwerekana sponge kumuri UV.
Kugirango ukemure ikibazo cyumuhondo cya polyurethane yoroheje, abakora sponge benshi, cyane cyane bamwe mubakora sponge yo murwego rwohejuru, bagerageza kunoza imikorere yo kurwanya umuhondo wa sponges wongeyeho antioxydants na stabilisateur yumucyo, ariko ingaruka ntizigaragara..Muyongeyeho, usibye kuba ukunda guhura n'umuhondo na mildew, umurongo w'imbere wakozwe muri sponge, ifite amazi adahagije kandi yinjira mu kirere, kandi ikagira ingaruka mbi zo kubira ibyuya, byoroshye kororoka.
