Umbiko Wocwaningo Lwemboni Ye-Polyurethane (Ingxenye A)

1. Uhlolojikelele lwemboni ye-Polyurethane

I-polyurethane (i-PU) iyinto ebalulekile ye-polymer, obubanzi bayo bezicelo kanye namafomu emikhiqizo ahlukahlukene ayenza ibe yingxenye ebaluleke kakhulu embonini yesimanje.Isakhiwo esiyingqayizivele se-polyurethane siyinikeza izakhiwo ezinhle kakhulu zomzimba namakhemikhali, okwenza isetshenziswe kabanzi ezindaweni ezifana nezokwakha, ezezimoto, ifenisha, nezicathulo.Ukuthuthukiswa kwemboni ye-polyurethane kuthonywa yizici ezihlukahlukene ezifana nesidingo semakethe, ukusungula izinto ezintsha zobuchwepheshe, nemithethonqubo yezemvelo, okubonisa ukuguquguquka okuqinile namandla okuthuthuka.

2. Uhlolojikelele lweMikhiqizo yePolyurethane

(1) Igwebu lePolyurethane (PU Foam)
I-polyurethane foamingenye yemikhiqizo eyinhloko yemboni ye-polyurethane, engahlukaniswa ibe igwebu eliqinile kanye negwebu eliguquguqukayo ngokuya ngezidingo ezahlukene zohlelo lokusebenza.Igwebu eliqinile livame ukusetshenziswa ezindaweni ezinjengokufakwa kwezakhiwo kanye namabhokisi okuthutha amaketanga abandayo, kuyilapho igwebu eliguquguqukayo lisetshenziswa kakhulu emikhiqizweni enjengomatilasi, osofa, nezihlalo zezimoto.Igwebu le-polyurethane libonisa izinto ezinhle kakhulu ezifana ne-lightweight, insulation eshisayo, ukumuncwa komsindo, nokumelana nokucindezela, okudlala indima ebalulekile empilweni yanamuhla.

• I-PU Foam eqinile:Igwebu eliqinile le-polyurethane liyi-foam enesakhiwo esivaliwe, esibonakala ngokuzinza okuhle kakhulu kwesakhiwo namandla emishini.Ivamise ukusetshenziswa ezinhlelweni ezidinga amandla aphezulu nobulukhuni, njengokuvala amabhilidi, amabhokisi okuthutha amaketanga abandayo, nezindawo zokugcina impahla eziqandisiwe.Ngokuminyana kwayo okuphezulu, igwebu le-PU eliqinile lihlinzeka ngokusebenza okuhle kokufakwa kwe-insulation kanye nokumelana nokucindezela, okuyenza ibe yinto ekahle yokwakha ingxilimbela kanye nokupakishwa kwamaketanga abandayo.
• I-Flexible PU Foam:I-Flexible polyurethane foam iyisisetshenziswa se-foam esinesakhiwo se-open-cell, eyaziwa ngokuthambile nokunwebeka.Isetshenziswa kakhulu ekwenzeni omatilasi, osofa, nezihlalo zezimoto, inikeze ukunethezeka nokwesekwa.Igwebu le-PU eliguquguqukayo lingaklanywa libe yimikhiqizo enobunzima obuhlukahlukene kanye nobulukhuni ukuze kuhlangatshezwane nezidingo zokunethezeka nokusekelwa kwemikhiqizo ehlukene.Ukuthamba kwayo okuhle kakhulu nokuqina kwayo kuyenza ibe yimpahla efanelekile yokugcwalisa ifenisha nengaphakathi lezimoto.
• Igwebu le-PU elizikhiphayo:Igwebu le-polyurethane le-self-skinning liyi-foam material eyakha isendlalelo sokuzivala ebusweni ngesikhathi sogwebu.Inobuso obushelelezi nobulukhuni obuphezulu, obuvame ukusetshenziswa emikhiqizweni edinga ukushelela kwendawo kanye nokumelana nokugqoka.Igwebu le-PU elizikhumbayo lisetshenziswa kakhulu kufenisha, izihlalo zezimoto, okokusebenza kokuqina, neminye imikhakha, ukuhlinzeka ngemikhiqizo ngokubukeka okuhle nokuqina.

(2) I-polyurethane Elastomer (PU Elastomer)
I-polyurethane elastomer inokunwebeka okuhle kakhulu nokumelana nokuguga, okuvame ukusetshenziswa ekwenzeni amathayi, izigxivizo, izinto zokudambisa ukudlidliza, njll. Kuye ngezidingo, ama-polyurethane elastomers angaklanywa abe imikhiqizo enobulukhuni obuhlukene kanye nezigaba zokunwebeka ukuze kuhlangatshezwane nezidingo zezimboni ezihlukahlukene. kanye nemikhiqizo yabathengi.

(3)I-Polyurethane Adhesive (PU Adhesive)

I-polyurethane adhesiveinezakhiwo ezinhle kakhulu zokubopha kanye nokumelana nemvelo, okusetshenziselwa kabanzi ekwenzeni izinkuni, ukukhiqizwa kwezimoto, i-textile adhesive, njll. I-polyurethane adhesive ingakwazi ukwelapha ngokushesha ngaphansi kwezimo ezihlukene zokushisa nezimo zomswakama, ukwakha izibopho eziqinile neziqinile, ukuthuthukisa ikhwalithi yomkhiqizo nokusebenza.

3. Ukuhlukaniswa nokusetshenziswa kwe-Polyurethane

I-ProductsI-Polyurethane, njengempahla ye-polymer eguquguqukayo, isetshenziswa kabanzi emikhakheni ehlukahlukene, ikakhulukazi ihlukaniswa ngezigaba ezilandelayo:
(1) Imikhiqizo Yegwebu
Imikhiqizo yegwebu ikakhulukazi ihlanganisa igwebu eliqinile, igwebu eliguquguqukayo, kanye negwebu elizikhiphayo, nezinhlelo zokusebenza ezihlanganisa:

• I-Insulation Yokwakha: Igwebu eliqinile livame ukusetshenziswa ekwakhiweni kokufakwa kwezinto zokwakha njengamabhodi okufakwa odongeni angaphandle namabhodi okufakwa ophahleni, okwenza ngcono ngempumelelo amandla ezakhiwo.
• Ukwenziwa Kwefenisha: Igwebu eliguquguqukayo livame ukusetshenziswa ekwenzeni omatilasi, osofa, izihlalo, ukuhlinzeka ngezihlalo ezinethezekile nokulala.Igwebu elizikhiphayo lisetshenziselwa ukuhlobisa indawo yefenisha, ukuthuthukisa ubuhle bomkhiqizo.
• Ukukhiqiza Izimoto: Igwebu eliguquguqukayo lisetshenziswa kakhulu ezihlalweni zezimoto, ngaphakathi kweminyango, linikeza okuhlangenwe nakho kokuhlala okunethezekile.Igwebu elizicwengayo lisetshenziselwa amaphaneli angaphakathi ezimotweni, amasondo okuqondisa, athuthukisa ubuhle nokunethezeka.

(2) Imikhiqizo ye-Elastomer
Imikhiqizo ye-elastomer isetshenziswa kakhulu kulezi zindawo ezilandelayo:

• Ukukhiqiza Izimoto: Ama-polyurethane elastomers asetshenziswa kakhulu ekukhiqizeni izimoto, njengamathayi, izinhlelo zokumiswa, izimpawu, ukuhlinzeka ngokumuncwa okuhle kokushaqeka kanye nemiphumela yokuvala, ukuthuthukisa ukuzinza nokunethezeka kwemoto.
• I-Industrial Seals: Ama-elastomer e-polyurethane asetshenziswa njengezinto zezimpawu zezimboni ezihlukahlukene, njenge-O-rings, ama-gaskets afaka uphawu, anokumelana okuhle kakhulu nokumelana nokugqwala, okuqinisekisa ukusebenza kokuvala kwemishini.

(3) Imikhiqizo Enamathelayo
Imikhiqizo enamathelayo isetshenziswa kakhulu kulezi zindawo ezilandelayo:

• I-Woodworking: Izinamatheliso ze-polyurethane zivame ukusetshenziselwa ukuhlanganisa nokuhlanganisa izinto zokhuni, ezinamandla okubopha okuhle nokumelana namanzi, asetshenziswa kabanzi ekwenzeni ifenisha, ukwenza izinkuni, njll.
• Ukukhiqiza Izimoto: Izinamatheliso ze-polyurethane zisetshenziselwa ukuhlanganisa izingxenye ezihlukahlukene ekukhiqizeni izimoto, njengamaphaneli omzimba, izigxivizo zamafasitela, ukuqinisekisa ukuzinza nokuvalwa kwezingxenye zezimoto.
