I-1,3-Propanediol (PDO)iyi-diol eguquguqukayo, evuselelekayo eye yazuza ukubaluleka okukhulu kwezimboni, ikakhulukazi ngenxa yokukhiqizwa kwayo okusekelwe ku-bio.1,3-propanediolUkubaluleka kwezimboni kulele ekuxhumaneni kwezinto zokusebenza okuphezulu (ikakhulukazi imicu ye-PTT) kanye ne-chemistry eluhlaza, okwenza izimpahla ezihlala isikhathi eside kanye nemikhiqizo yabathengi kube nomphumela ophansi wemvelo.
·Ama-polymers kanye nezindwangu (Isicelo Esikhulu Kunazo Zonke)
Izinto zokusetshenziswa ze-Polytrimethylene Terephthalate (PTT): I-PDO ihlanganiswe ne-terephthalic acid ukuze ikhiqize i-PTT. (I-PTT isetshenziswa kabanzi kwi-fibre yekhaphethi, i-Apparel & Activewear kanye ne-Engineering Plastics.)
·Izinhlanganisela nama-Resins
Ingasetshenziswa njenge-monomer ukuguqula ama-Unsaturated Polyester Resins (ama-UPR) athuthukisa ukuguquguquka, ukuqina, kanye nokuzinza kwe-hydrolytic ezisetshenziswayo njengezingubo zejeli zasolwandle, amathangi, kanye nezingxenye zezimoto.
Ukwenza ama-Polyurethane e-Thermoplastic (ama-TPU): Ama-polyol asekelwe ku-PDO angakha ama-TPU anezakhiwo ezithuthukisiwe zezinyawo zezicathulo, izingxenye zangaphakathi zezimoto, kanye namapayipi aguquguqukayo.
Isetshenziselwa ukwakha ama-polyurethane asebenza kahle kakhulu anokuqina kwe-UV okuthuthukisiwe, ukumelana namakhemikhali, kanye nokuguquguquka kwezinga lokushisa eliphansi kwe-Coatings, Adhesives, Sealants, kanye ne-Elastomers (CASE).
·Ama-Liquid Detergents kanye nama-Cleaning Formulations
Isebenza njengesinyibilikisi, isilungisi se-viscosity, kanye ne-ejenti yokukhipha amabala. Isiza ekumiseni ukungcola, ivimbele ukwakheka kabusha kwezindwangu, futhi ithuthukise ukuzinza kwezihlanzi ze-enzyme.
·Uketshezi Lokususa Iqhwa/Lokulwa Nokuqanda
Isithako esiyinhloko ezinhlotsheni eziningi ze-Type IV "anti-icing" ze-Aircraft De-icing Fluids. Ihlinzeka ngokucindezeleka okuhle kakhulu kwe-freeze-point futhi yakha ifilimu evikelayo, enamathelayo evimbela ukwakheka kweqhwa ezindaweni zezindiza isikhathi eside "sokulinda" ngaphambi kokusuka. Ayinabo ubuthi futhi inobungani nemvelo kakhulu kunezinye i-glycol zendabuko njenge-ethylene glycol.
·Sula amandla okusebenzisa emkhakheni wezitini zokwakha
Njenge-ejenti yokwelapha yangaphakathi esebenza kahle kanye ne-shrinkage reduction, kanye ne-ejenti yokulwa nokuqandisa eqhubekayo
I-PDO iyi-ejenti ephumelela kakhulu yokugcina amanzi emvelo. Uma ixutshwe nodaka ukuze kukhiqizwe izitini, ingavala umswakama isikhathi eside futhi iwukhulule kancane ngesikhathi sesigaba sokugcina sokumuncwa kwesimende. Lokhu kunciphisa kakhulu ukushwabana nokomisa nokuqhekeka, kukhuthaza ukumuncwa kwesimende okuphelele nokulinganayo, kuthuthukisa amandla nobukhulu bezitini kamuva, futhi kuthuthukisa ukumelana kwezitini nemijikelezo yokuqandisa nokuncibilika.
-Njenge-binder noma i-modifier ephilayo
I-PDO ingasetshenziswa njenge-polyol ukuze ihlanganyele ekwakhiweni noma ekuguqulweni kwama-polymer (njenge-polyurethanes, ama-polyester resins), angasetshenziswa njengesinamathelisi semicu noma ama-aggregates ngaphakathi kwesitini, okuthuthukisa ubuqotho obuphelele. Ukwemboza okuvikelayo ebusweni bezitini kunikeza imisebenzi efana nokuvinjelwa kwamanzi, ukulwa nokushisa kanye nokulwa nokungcola.
-Njengesiqinisi sezitini ezinegwebu noma ezilula
Izakhiwo zayo ze-surfactant zisiza ekuqiniseni isakhiwo sebhamuza ngesikhathi senqubo yokwenza igwebu, okwenza izikhala zangaphakathi zesitini zifane futhi zibe zincane. Ngenxa yalokho, kutholakala izitini ezilula ezisebenza kahle ekushiseni kanye namandla aphezulu.
