Kenyelletso e qaqhileng
E Ethylene-Vinyl Acetate Copolymer, e leng khanye ka lebaka la Eva, ke motsamaisi ea entsoeng ka mongobo o entsoeng ka motsoako oa menomers ea exnyl acetate. Ke boitsebiso bo temaneng tse sebelisoang likopanong tse fapaneng ka lebaka la mathata a teng.
Eva Copolymer o na le ntlha e qhang, ho fetoha le maemo le letle, le ho ba le ho leka-lekana hantle le ho hlaka. E hanyetsoa ke metsi, mahlaseli a UV le lik'hemik'hale, tse etsang hore e be loketseng lits'ebetso tsa kantle. E boetse e na le moea o motle ho ba bangata ho limilione tse ngata, o etsa hore o sebelise e le mokhoa oa ho hlaba kapa ho khomarela.
E 'ngoe ea lits'ebetso tse ka sehloohong tsa Eva e har'a tlhahiso ea foams. E sebelisoa haholo ho etsa lisebelisoa tsa ho fokotsa le ho fofa, tse kang soles, lisebelisoa tsa moatlelete le lisebelisoa tsa ho tsamaisa thepa. Maba foomafong a fana ka mosamo, le ho khothatsa.
Moruotsi le leng o boetse o sebelisoa ha a etsa lifilimi le marama. E hlakile, ho feto-fetoha le maemo, ho ipolaea, ho fetoha le mocheso o tlase ho etsa hore ho be loketse lits'ebetso tse kang collagen, khalase ea letsatsi le letsatsi e nang le letsatsi.
Litsela tsa motlakase le tsa futhumatsang tsa Eva li etsa hore e be thuso mabapi le indasteri ea terata le ea cable. Ho sebelisoa thepa ka seva le lisebelisoa tsa tlhahlobo le ho kenya lithapo tsa motlakase le likompele.isang
Ka kakaretso, ethylene-vinyl acetate copolymer ke boitsebiso bo fapaneng ka thepa e ntle e etsang hore e be e loketseng likopo tse fapaneng.
Kopo
E Ethylene-Vinyl Acetate Copolymer (Eva) e na le likopo tse fapaneng tsa likopanyana ka har'a indasteri e fapaneng ka lebaka la motsoako o ikhethang oa thepa. Mona ke lisebelisoa tse tloaelehileng tsa Eva:
Lieta tsa maoto:Eva o sebelisitsoe haholo tlhahisong ea lieta, haholo-holo bakeng sa bohareng le insoles. E fana ka tšusumetso, ho monya khatello ea kutlo, le ho fetoha le maemo, ho e etsa khetho e tummeng ea lieta tsa baatlelete, meqathatso le lisepa.
Ho paka:Eva e sebelisoa ho likopo tsa ho paka ha e fana ka khanyetso le maemo. E sebelisoa hangata e le lits'oants'o tsa ts'ireletso, foauche, le mabokose a mabokose kapa lijana ho sireletsa lihlahisoa tse bobebe kapa tse fokolang nakong ea lipalangoang.
Lits'ebetso le lifofane:Moemeli oa Bajuda e sebelisoa e le thepa ea motheo ho hlahiseng lidheshe le li-seala. E fana ka kamano e ntle ho ea libakeng tse fapaneng, e kang lipopae, tšepe le patsi, e etsa hore e be e loketseng likopo tsa bona.
Khoebo ea terata le Cable:Eva e sebelisoa e le thepa ea puo bakeng sa lithapo tsa motlakase le likhoele tse ka ntle ho thepa ea eona e ntle ea motlakase. Ho re khanyetsa mongobo oa mongobo, lik'hemik'hale le botsofali, le botsofali, li netefatsa polokeho le ho ts'epahala ha tsamaiso ea motlakase.
Filimi le sheet:Hangata Eva e sebelisoa ho hlahisa lifilimi le lishiti tse nang le bokhachane tse fapaneng. Lifilimi tsena li fumana lits'ebetso tsa bonono, mekotla ea limela ea limela, ho tšela lijo, le khalase e nang le letsatsi.
Lisebelisoa tsa bongaka:Eva e sebelisoa indastering ea bophelo bo botle ho hlahisa lisebelisoa tsa bongaka, tse kang li-catheter, tubing le li-e bulule. E fana ka biocondomatight, ho feto-fetoha le maemo le mokhoa o bonolo o hlokahalang bakeng sa likopo tsa bongaka.
Ho bapala le lihlahisoa tsa boithabiso:Eva e sebelisoa haholo tlhahisong ea lintho tsa ho bapala le lihlahisoa tsa boithabiso, ho kenyeletsoa le li-puzzle tsa foam, lisebelisoa tsa lipalesa, lisebelisoa tsa lipapali tsa yoga. E fana ka tšusumetso, polokeho le boipelaetso bakeng sa lits'ebetso tsena.
Likarolo tsa likoloi tsa likoloi:Lisebelisoa tsa phaole li sebetsa lits'ebetsong tsa koloi bakeng sa boikhathollo bo nepahetseng bakeng sa molumo o nepahetseng oa likhohlano E thusa ho fokotsa lerata, o matlamotšeng, 'me u fane ka tšireletso ka har'a koloi.
Tsena ke mehlala e 'maloa feela ea lits'ebetso tse ngata tsa eva. Ho fapana ha eona, ho itekanetse le ho qobella ho etsa hore e sebelise hangata indastering e fapaneng.
