Yintoni esetyenziselwa?
Izazinzulu ziye zafumanisa ukuba I-Polyurethane inokuguqulwa ibe yimisonto encinci Ke i-nylon yokuqala ivele, apho isitokhwe senza isitokhwe. Kule minyaka idlulileyo, waphuculwa kwiintsinga ze-spandex. Enkosi kwimpumelelo yanamhlanje, itekhnoloji ikuvumela ukuba wenze Uluhlu olubanzi lweelaphu zePolyurethane: Ukusuka kwisikhumba esenziwe ngobugcisa (kubandakanya i-suede okanye i-velor) kunye ne-EO-amabali e-Outlewear kunye nefanitshala i-phuctos, iijacket, izixhobo ezahlukeneyo, iimveliso ezahlukeneyo, amayeza kunye neemveliso zezemidlalo. Ukongeza, lonto isetyenziselwa ukudala ukukhululeka kakhulu, izixhobo ezinganyangekiyo nezingahambelani nemozulu, ezinje ngoovimba, iijekethi zezemidlalo kunye nemvula, izihlangu kunye nezihlangu.
Inyaniso! I-Thermoplastic Polyurrethane Elastomers zinokubunjwa kwiifibers ezahlukeneyo. Xa befihla, izinto eziguqukayo zibizwa ngokuba yi-spandex. Izinto ze-elastic ziyafuneka ukwenziwa kweesokisi, iibras, ukuxhasa imikhono, i-swits, izixhobo zemidlalo kunye nezinye izinto ezininzi.
Eyona nto iphambili kwesikhumba sokwenyani phambi kwe-leetherererete kukuphefumla kwayo kunye nokwazi ukubola kwebhayiloji. Kodwa ngo-1963, izazinzulu ezivela e-USA zeza nokuphefumla kwe-ecocon ephilayo kwiipropathi zazo, ithambile kwaye i-elastiki kwaye ilula kakhulu ngokobunzima.
Itekhnoloji yobuqhetseba ngokuchasene nokusetyenziswa gwenxa kwezilwanyana kunye nokwenza Ulusu lwePolyurethane Ukhetho lwe-eco-friend kunye nokusebenzisa ubutyebi bendalo. I-Polyredthane I-Polyrics isetyenzisiwe Kumashishini amaninzi, kuxhomekeka kubume babo bekhemikhali kunye neepropathi ezifunyenwe kwinkqubo yemveliso.
Yeyona nto iphambili kwezi mveliso zilandelayo.

- Ifanitshala yefanitshala kunye nemveliso yemoto (i-upholstery prolstery yempahla, iifilitha ezithambileyo, iMatracts).
- Impahla yezonyango (iigloves, ephezulu yeengoma ezingaphantsi).
- Iimveliso zokuqubha kunye nokhenketho (ukuhlangula izibane kunye neenqanawa, iijekethi ze-membrane kunye nezihlangu).
- Iimpahla zabantwana (iidayithi ezinokuphinda zisebenze).
L. Gore kunye neMidyulo ngo-1976 i-gore-tags -Amanzi-ipeyinti, kodwa kwangaxeshanye izinto eziphefumlelweyo. Ukusukela ngoko, isetyenziselwe ukufakelwa kwezonyango, ukufunyanwa kweengcingo kunye nokuveliswa kweengubo kunye nezihlangu. I-Gore-Tegrane Yaba nguBrand olwaziwayo, onika impahla ye-SKI kunye nezihlangu ezihamba neentaba, iijackethi, iijackethi kunye nee-overalls kumatem kwimisebenzi yangaphandle. Ezo zixhobo ngokufanelekileyo ziyagcina ummanzi kuzo zonke iimeko zemozulu.
Inomdla! Abanye abantu basePolyurethane bakhala ngesikhumba se-artifififififififififififififififififififififififififififififififififififififififififififififififififikic yezazihlangu, i-upholstery ye-sofa kunye nezinye iimpahla ezininzi.
Iindwangu zePolyurethane yimiphunga, kukho ukuphefumla kwaye ungaphefumli. Njengommiselo, gcina iipropathi zabo ubuncinci kangangee-100 kwimijikelezo engama-100 kumatshini wokuhlamba ngaphandle kokwenzakaliswa sisixhobo. Kulula ukusebenza nento, kwasekwa ukuba isetyenziselwe ukusetyenziswa kwezibhedlele, apho izinto ezihlala ziqinileyo nezingasebenziyo ziyafuneka.
Iimpawu zomsebenzi kunye nokukhathalela
I-Polyurethanes i-piedthanes kunye nesikhumba se-ardatifibifizulu Kukho ithutyana, kwaye kuba bangamanzi, ubumdaka bususwa ngokulula ngesepha kunye nesiponji esithambileyo. Inokucocwa ngokwaimfakazi yemineral, kodwa iikhemikhali eziqinileyo, ezinjenge-acetone okanye iviniga, ayinakuchaphazela imbonakalo. Ngokwemiyalelo yokhathalelo kunye nemiyalelo yokusebenza (ihlala ijonga ilebhile kwizinto zakho), uninzi lweemveliso ezenziwe nge-polyurethane izicubu zinokupasiswa ukuba zicoceke Beka kumatshini wokuhlamba kunye nomgubo wokuhlamba oqhelekileyo. ukuxolelwa.
Ngokungafaniyo nezixhobo zePolyurethane, i-Gore-Tex ineendawo zokuphefumla ezifuna ukucocwa rhoqo kunye nokuntywila kunye nokubila kungaphazamisi
