Kungani ukhethe i-polyurethane yama-casters ezimboni futhi yiziphi izinzuzo zayo?

I-Polyurethane (PU), igama eliphelele le-polyurethane, iyinhlanganisela ye-polymer, eyakhiqizwa ngo-1937 ngu-Otto Bayer nabanye. I-Polyurethane inezigaba ezimbili eziyinhloko: i-polyester ne-polyether. Zingenziwa zibe amapulasitiki e-polyurethane (ikakhulukazi i-foam), imicu ye-polyurethane (eyaziwa ngokuthi i-spandex eShayina), irabha ye-polyurethane kanye nama-elastomers. I-Polyurethane iyinto ye-polymer efanelekile ukusetshenziswa njengesimbozo samasondo ekwenziweni kwama-casters ezimboni.

Izinzuzo eziyinhloko zama-polyurethane casters ikakhulukazi yilezi ezilandelayo:

Okokuqala, ukusebenza kobubanzi obulungisekayo

Izinkomba zokusebenza eziningana ezibonakalayo nezikagesi zingalungiswa ngokukhetha izinto zokusetshenziswa kanye namafomula, ngaphakathi kobubanzi obuthile bezinguquko eziguquguqukayo, ukuze kuhlangatshezwane nezidingo ezihlukile zomsebenzisi zokusebenza komkhiqizo.

Okwesibili, ukumelana okukhulu kokuhuzuka
Uma kukhona amanzi, uwoyela nezinye izimo zokusebenza zemidiya yokumanzisa, ama-polyurethane casters ukumelana nokuguguleka kuvame ukuba izikhathi eziningana kuya kweziningi kunezinto zerabha ezivamile. Izinto zensimbi ezifana nensimbi nezinye izinto eziqinile, kodwa hhayi ngempela ukuthi azigugi!

Okwesithathu, izindlela zokucubungula, ukusebenza kabanzi
Ama-elastomer e-polyurethane angabunjwa ngerabha yenhloso ejwayelekile ngokwenza ipulasitiki, ukuxuba kanye ne-vulcanizing (MPU); angenziwa futhi abe irabha ewuketshezi, ukuthulula kanye nokubumba noma ukufutha, ukuvala kanye nokubumba kwe-centrifugal (CPU); angenziwa futhi abe izinto ezi-granular kanye namapulasitiki ajwayelekile ngokujova, ukukhipha, ukuhlanganisa, ukubhoboza kanye nezinye izinqubo (CPU). Izingxenye ezibunjiwe noma ezifakwe umjovo, ngaphakathi kobubanzi obuthile bobulukhuni, nazo zinganqunywa, zigaywe, zibholwe kanye nokunye ukucutshungulwa kwemishini.

Okwesine, ukumelana namafutha, ukumelana ne-ozone, ukumelana nokuguga, ukumelana nemisebe, ukumelana nokushisa okuphansi, ukudluliselwa komsindo okuhle, amandla okunamathela aqinile, ukuhambisana kahle kwezinto eziphilayo kanye nokuhambisana kwegazi. Lezi zinzuzo yizona kanye izizathu ezenza ama-polyurethane elastomer asetshenziswe kabanzi kwezempi, ezindizayo, kuma-acoustic, kwi-biology nakweminye imikhakha.
