Izici kanye nokusetshenziswa okuyinhloko kwe-polyurethane
Njengoba amaqembu aqukethwe kuma-macromolecules e-polyurethane wonke engamaqembu aqinile, futhi ama-macromolecules aqukethe izingxenye eziguquguqukayo ze-polyether noma i-polyester, i-polyurethane inokulandelayo:

Isici
①Amandla aphezulu emishini nokuzinza kwe-oxidation;
② Inokuvumelana nezimo okuphezulu nokuqina;
③Inokumelana nowoyela okuhle kakhulu, ukumelana ne-solvent, ukumelana namanzi nokumelana nomlilo.

Ngenxa yezakhiwo zayo eziningi, i-polyurethane inezinhlobo eziningi zokusetshenziswa.I-polyurethane isetshenziswa kakhulu njengesikhumba sokwenziwa se-polyurethane, igwebu le-polyurethane, i-polyurethane enamathela, i-polyurethane adhesive, irabha ye-polyurethane (i-elastomer) ne-polyurethane fiber.Ngaphezu kwalokho, i-polyurethane isetshenziselwa ubunjiniyela bomphakathi, ukumba indawo, izimayini kanye nobunjiniyela be-petroleum ukuvimba amanzi nokusimamisa izakhiwo noma imigwaqo;njengempahla yokugandaywa, isetshenziselwa ukugijima amathrekhi ezinkundleni zemidlalo, phansi kwangaphakathi kwezakhiwo, njll.

Umsebenzi ophansi womshini wokugcwalisa ugwebu
1. Umshini we-polyurethane foaming unezici zezinzuzo zezomnotho, ukusebenza okulula nokugcinwa, njll., futhi kungenziwa ngokwezifiso ngokuvumelana nezidingo zamakhasimende.

2. Isikrini sokuthinta i-Adopt plc kanye nephaneli yokusebenza komshini womshini womuntu, okulula ukuyisebenzisa, nokusebenza komshini kucacile lapho uthi nhla.Ikhanda elixutshwayo linomsindo ophansi, liqinile futhi liqinile, kanye nephampu engenisiwe m...威而鋼
ikhula ngokuqinile.Umgqomo wohlobo lwe-Sandwich, umphumela omuhle wokushisa ongashintshi.

3. Ilungele ukukhiqizwa kwemicamelo ye-polyurethane, amasondo okuqondisa, obhampa, isikhumba esenziwe mathupha, i-high rebound, i-rebound ehamba kancane, amathoyizi, okokusebenza kokuqina, ukufakwa kwe-thermal, izihlalo zebhayisikili,
Amakhushini ezihlalo zezimoto nezithuthuthu, igwebu eliqinile, amapuleti esiqandisi, okokusebenza kwezokwelapha, ama-elastomer, amasoli ezicathulo, njll.

Isistimu yokulawula ye-PLC:Ikhwalithi enhle kakhulu, ukugcinwa okulula, okulula futhi okuguquguqukayo, ukusebenza okuzinzile, izinga lokuhluleka eliphansi.

Iphampu yemitha yomkhiqizo:Ukulinganisa okunembile, izinga lokuhluleka eliphansi kanye nokusebenza okuzinzile.

Ukuxuba Ikhanda:Isilawuli se-valve yenaliti (i-valve yebhola), isigqi sokuthulula esinembile, ukuxuba okugcwele kanye nomphumela omuhle wokugwedla.

I-Stirring Motor:Ifanele ukusebenza okuqhubekayo ngesivinini esisheshayo nezinzile, ukusebenza kahle okuphezulu, umsindo ophansi nokudlidliza okuncane.

I-PU self-skinning uhlobo lwepulasitiki eyigwebu.Yamukela ukusabela kwe-synthesis ye-polyurethane enezingxenye ezimbili.Isetshenziswa kabanzi emikhakheni eminingi efana nesondo lokuqondisa, iphaneli yezinsimbi, isitulo somugqa womphakathi, isihlalo sokudlela, isitulo sezindiza, isihlalo sesibhedlela, isihlalo selabhorethri nokunye.
