Kwiminyaka yakutshanje, ngophuhliso olomeleleyo "loqoqosho lwakhe" kunye nokunyuka kweentengiso ze-intanethi, umkhondo wempahla yangaphantsi yabasetyhini baseTshayina wenza utshintsho olungazange lubonwe ngaphambili kwaye utsale ingqwalasela engakumbi evela kwinkunzi.Ngokutsho kwe-iiMedia Research, i-Neihui, i-Oxygen, i-Inman, i-Qingwei, kunye ne-Ubras zonke zifumene inkxaso-mali.Ngokwezibalo ezingaphelelanga, ngo-2018 kuphela, utyalo-mali kunye nenkxaso-mali yoshishino lwempahla yangaphantsi yaseTshayina idlule kwi-yuan yezigidi ezingama-200.Ukususela ngo-2010, imfuno yabathengi yempahla yangaphantsi e-China iye yaqhubeka ikhula: ngo-2010, imfuno yeengubo zangaphantsi kwilizwe lam yayiyi-6.1 yezigidigidi kuphela.Ngo-2019, imfuno yokusetyenziswa kwempahla yangaphantsi yaseTshayina iya kufikelela kwi-16.77 yeebhiliyoni zeebhiliyoni, kunye nesantya sokukhula komndilili wonyaka we-11.9%.Okwangoku, baphantse babe ngama-10,000 abavelisi bempahla yangaphantsi yasekhaya, kwaye kukho ngaphezu kwama-3,000 eemveliso zempahla yangaphantsi yabasetyhini, kodwa ngaphezu kwe-90% yeempawu zinemilinganiselo yokuthengisa engaphantsi kwe-100 lezigidi zeeyuan, kwaye iibrendi ezimbalwa zigqitha kwibhiliyoni enye yeyuan.Ngenxa yesi sizathu, ukususela ekungeneni komzila, iimpawu ezahlukeneyo ziye zaqhubeka zongeza "ii-gimmicks" kwiimveliso zabo - ngoku phantse zonke iimpahla zangaphantsi ezinokuthiwa ziimpawu ezidumileyo zikhuthaza "ingqiqo yeteknoloji".
Nokuba sisisiseko sebrasi yenkumbulo enwenwe kakhulu endayithanda ngeentsuku zangaphambili, okanye “umlingo obhityileyo kakhulu” welaphu le-Tingmei “elastiki enamacala asibhozo”, okanye i-Ubras edume ngakumbi “ayinamkhondo kwaye ayinaringi yentsimbi” , i-patentable water drop coaster enokususwa, okanye i-Banana's Stressfree non-inductive technology kunye ne-ZeroTouch non-inductive support technology igxininisa "uluvo lweteknoloji" yempahla yangaphantsi.Njengenxalenye ebalulekileyo yeengubo zangaphantsi zabasetyhini, ugxininiso lwezinto eziphathekayo kunye nomsebenzi wesifuba sesifuba nazo zihamba ngoluhlu lweenguqu kunye neemarike.Namhlanje, umbhali uya kukuthatha ukuba uqonde izixhobo zogwebu kwintengiso yempahla yangaphantsi yesifuba yabasetyhini nganye nganye.
Izinto eziqhelekileyo zephedi yesifuba ziquka i-foam, i-foam yememori, i-silicone foam, i-latex, kunye ne-3D yekotoni ethe tye.
isipontshi
Xa kufikwa kwizipontshi, into yokuqala ethi qatha ezingqondweni zethu sisiponji sokuhlambela xa sihlamba okanye isipontshi sokucoca ukuhlamba izitya.Ezi zithambile ukubamba, zinemingxuma emincinci yonke indawo, kwaye izinto ezoyikisayo kancinci.Akunjalo nje kuphela i-absorbent ephezulu, kodwa kungakhathaliseki ukuba "ixhaphake" kangakanani, iya kubuyela kwimeko yayo yangaphambili xa ikhutshwa, kwaye ineplastiki enhle.Kodwa uyazi ntoni?Ngenene izipontshi zizilwanyana, isilwanyana samandulo samandulo.Imizimba yabo ayinayo imilo ezinzileyo kwaye inemingxuma emincinci emincinci kwiindonga zazo.Zihlelwa njengezilwanyana ezinamaqhekeza.Kukho iintlobo ezininzi, amashumi amawaka.Uninzi lwazo lukhula kumanzi eMeditera, kwiGulf of Mexico naseBahamas.
Kamva, ngenxa yophuhliso lwenzululwazi yezinto eziphathekayo kunye nokusetyenziswa kwezixhobo zepolymer, ngoku sinokuthenga ngokulula iimveliso zesiponji ezinexabiso eliphantsi, iziponji zokwenziwa ikakhulu ezineenqabunga zobusi ezenziwe ngeepolima zeplastiki ezinogwebu.
Kukho iintlobo ezininzi zeziponji zokwenziwa, kodwa ngengqiqo emxinwa, abantu baqhele ukulinganisa "izipontshi" kunye ne-polyurethane foams ethambileyo eqhelekileyo, eyenziwe nge-polyisocyanates kunye ne-polyols exutywe namanzi, i-catalysts kunye ne-stabilizers.Le nto ye-foam eguquguqukayo inokumelana ne-oxidation elungileyo kunye nokumelana ne-solvent, kwaye isoloko isetyenziselwa iingubo, iingubo ezidibeneyo zempahla, ukuveliswa kweengubo zangaphantsi, njl., kodwa ngenxa yokunganyangeki kwe-hydrolysis ye-polyester ngokwayo, ubomi benkonzo ye-foam kule meko iya hayi ixesha elide.Imekobume eshushu nefumileyo., isenzeko esityheli siya kubonakala emva kwexesha elithile.
Ngokombono wezongezo kwimveliso yesiponji, izizathu zesiponji phuzi zimi ngolu hlobo lulandelayo:
Ngexesha le-foaming / inkqubo yokucutshungulwa, isiponji sijika sibe tyheli ngenxa yokuguga kwe-thermal oxidation okubangelwa kubushushu obuphezulu;
Ukufuthwa kwerhasi kunye nokutyheli ngenxa yokuchaphazeleka kwinitrogen oxides (NOx) emoyeni;
Utyheli ngenxa yokuvezwa kwesipontshi kukukhanya kweUV.
Ukuze kulungiswe ingxaki ye-yellowing ye-foam ye-polyurethane eguquguqukayo, abaninzi abavelisi be-sponge, ngokukodwa abavelisi be-sponge abaphezulu, bazama ukuphucula ukusebenza kwe-sponges anti-yellowing ngokudibanisa i-antioxidants kunye ne-stabilizers yokukhanya, kodwa umphumo awubonakali..Ukongezelela, ukongeza kwi-yellowing kunye ne-mildew, i-lining ye-underwear yenziwe nge-sponge, enokungena kwamanzi okwaneleyo kunye nokunyanzeliswa komoya, kwaye inomphumo obuthathaka, okulula ukuzala ibhaktheriya.
