Neck Pillow Material

Igwebu leMemori efudumeleyo
I-foam yenkumbulo efudumeleyo yaphuhliswa kwi-1960 ngu-Healthman, i-subsidiary ye-NASA. Ibonisa{2}}isakhiwo seseli evulekileyo kwaye ineempawu zokukhululeka koxinzelelo lwe-thermal, iyenze ibe luxinzelelo olunovakalelo lwe-thermal{3}}isixhobo sokukhulula. UHealthman wasebenzisa le mathiriyeli kwisiphekepheke. Yayiyilelwe ukukhulula uxinzelelo koosomajukujuku kunye nokukhusela imigca yabo, ngakumbi ngexesha lokuphinda bangene kunye nokumka kwisiphekepheke, xa uxinzelelo koosomajukujuku lukhulu kwaye luyingozi kakhulu. Esi sixhobo senzelwe ukukhusela ukhuseleko loosomajukujuku. Ekuqaleni kweminyaka yoo-1990, inkampani yaseSweden iFagerdala yaphinda yaphuhlisa ukuba isetyenziselwe uluntu (lwezonyango), ekuqaleni yafumana ukwamkelwa ngokubanzi kukhathalelo lwezonyango olungxamisekileyo kunye neenkqubo zokubeka iliso. Yakhawuleza yafumana udumo kumazwe aphuhlileyo, ngakumbi amazwe anolwazi ngempilo{10} njenge Japan.

Ukuthontelana
Lo mqamelo ophuculiweyo u{0}owenziwe ngePVC, unikezela ngenkxaso ethambileyo yoMqamelo o{1}olunezibonelelo ezongezelelweyo zokuphatheka kunye nokugcinwa lula. Lukhetho oludumileyo lokuhamba, ukuqhuba, iiofisi, kunye namagumbi okufundela. Nangona kunjalo, ngenxa yokuba i-PVC iqinile ngokwendalo, iiplastiki zihlala zongezwa ngexesha lenkqubo yokuvelisa ukuyithambisa. Iimathiriyeli eziqhelekileyo zePVC, ezikwaziwa ngokuba ziiphthalates, zinokuqulatha i-20% ukuya kwi-60% ye-phthalates. Iziphumo ezinobungozi ze-phthalates zezi: ebantwini nakwizilwanyana, iiphthalates zisebenza njenge-estrogen, zinyusa umngcipheko womhlaza wamabele kwabasetyhini kunye nokonakalisa inkqubo yokuzala yabantwana abangamadoda bexesha elizayo, kunye neempembelelo zempilo zibonakala ngakumbi kubantwana. Ngaphaya koko, ukusetyenziswa kwezinto zokuncamathelisa xa uncamathelisa umhlambi kumphezulu wePVC kwandisa ubutyhefu bemveliso.

Kabini-isakhiwo somaleko

Ngenxa yokungahlambeki kwendalo yePVC, U{1}}imiqamelo iza nemiceli mngeni yokucoca. Ngokuqhelekileyo zilahlwa emva kwenani elithile lokusetyenziswa, zinciphisa ubomi bazo. Ngaphaya koko, izixa ezikhulu zezinto ezilahliweyo zePVC zinegalelo kungcoliseko lwendalo esingqongileyo. Ngoko ke, -isakhiwo semaleko esiphindiweyo{6}}i-liner yangaphakathi + isigqubuthelo sangaphandle{8}}sivele kwimarike. U{10}}umphilisi wonyango lwemagnethi ukhathalelo lwempilo U{11}}umqamelo ngumzekelo{12} owaziwayo. Isebenzisa i-inflatable liner yangaphakathi eyenziwe ngezinto ezihambelana nokusingqongileyo kunye nempilo, ngaphandle kweengozi zempilo ezinxulumene nePVC eqhelekileyo. Kwangaxeshanye, ngenxa yokuba isigqubuthelo sayo sangaphandle senziwe ngevelvet ethambileyo, ithambile kwaye ikhululekile, kwaye ukunxiba okunxibayo kufana ngakumbi ne-foam yememori.
