I-1,3-Propanediol (PDO)yi-diol eguquguqukayo, evuselelekayo eye yafumana ukubaluleka okukhulu kwezoshishino, ingakumbi ngenxa yemveliso yayo esekwe kwi-bio.I-1,3-propanediolUkubaluleka kwemizi-mveliso kukwindawo apho izinto ezisebenza kakuhle (ingakumbi iifayibha ze-PTT) kunye nekhemikhali eluhlaza, nto leyo evumela iimpahla ezihlala ixesha elide kunye neemveliso zabathengi ukuba zingachaphazeleki kakhulu yindalo esingqongileyo.
·IiPolymers kunye neeLaphu (Eyona ndlela iphambili yokusebenzisa)
Izinto ezisetyenziswa kwiPolytrimethylene Terephthalate (PTT): I-PDO idityaniswe ne-terephthalic acid ukuvelisa i-PTT. (I-PTT isetyenziswa kakhulu kwifayibha yekhaphethi, kwiimpahla kunye neempahla ezisebenzayo kunye neeplastiki zobuNjineli.)
·IiComposites kunye neeResins
Ingasetyenziswa njenge-monomer yokutshintsha ii-Unsaturated Polyester Resins (ii-UPR) eziphucula ukuguquguquka, ukuqina, kunye nokuzinza kwe-hydrolytic kwizicelo ezifana neengubo zejeli zaselwandle, iitanki, kunye nezixhobo zemoto.
Ukwenza iiPolyurethanes zeThermoplastic (iiTPU): iiPolyols ezisekwe kwiPDO zinokwenza iiTPU ezineempawu eziphuculweyo zeentlantsi zezihlangu, iindawo zangaphakathi zeemoto, kunye neepayipi eziguquguqukayo.
Isetyenziselwa ukwenza ii-polyurethanes ezisebenza kakuhle ezinozinzo oluphuculweyo lwe-UV, ukumelana neekhemikhali, kunye nokuguquguquka kobushushu obuphantsi kwiiCoatings, Adhesives, Sealants, kunye ne-Elastomers (CASE).
·Izicoci zolwelo kunye neefomyula zokucoca
Isebenza njengesinyibilikisi, isiguquli se-viscosity, kunye ne-arhente yokukhulula amabala. Inceda ekumiseni ukungcola, ithintele ukuphinda kubekwe amalaphu, kwaye iphucula uzinzo lwezixhobo zokucoca ii-enzyme.
·Ulwelo lokususa i-icing/Ulwelo oluchasene ne-icing
Isithako esibalulekileyo kwii-Type IV "anti-icing" fluids ezininzi ze-Aircraft De-icing Fluids. Inika indawo yokukhenkceza egqwesileyo kwaye yenza ifilimu ekhuselayo, ekrakra ethintela ukwakheka komkhenkce kwiindawo zeenqwelo-moya ixesha elide "lokulinda" ngaphambi kokuba zisuke. Ayinabungozi kangako kwaye inobuhlobo nokusingqongileyo kunezinye ii-glycols zemveli ezifana ne-ethylene glycol.
·Isixhobo esicacileyo sokusebenzisa izitena zokwakha
Njengearhente yokunyanga yangaphakathi esebenzayo kunye neyokunciphisa ukushwabana, kunye nearhente ezinzileyo yokulwa nokuqandisa
I-PDO sisixhobo esisebenza kakuhle kakhulu sokugcina amanzi kwindalo. Xa ixutywe kwi-mortar ukuze kwenziwe izitena, inokuvalela umswakama ixesha elide kwaye iwukhulule kancinci ngexesha lokugqibela lokufuma kwesamente. Oku kunciphisa kakhulu ukushwabana kokoma kunye nokuqhekeka, kukhuthaza ukufuma kwesamente okupheleleyo nokufanayo, kuphucula amandla kunye noxinano lwezitena kamva, kwaye kuphucula ukumelana kwezitena kwimijikelo yokuqandisa nokunyibilika.
-Njengesixhobo sokubopha okanye sokuguqula izinto eziphilayo
I-PDO ingasetyenziswa njenge-polyol ukuze ithathe inxaxheba ekuhlanganiseni okanye ekuguquleni ii-polymers (ezifana ne-polyurethanes, ii-polyester resins), ezingasetyenziswa njengesincamathelisi seefayibha okanye ii-aggregates ngaphakathi kwesitena, nto leyo ephucula ukuthembeka kwayo yonke. Ukwaleka okukhuselekileyo kumphezulu wezitena kunika imisebenzi efana nokungangenisi amanzi, ukuthintela ukubola kunye nokuchasana nokungcola.
-Njengesixhobo sokuqinisa izitena ezinegwebu okanye ezikhaphukhaphu
Iimpawu zayo ze-surfactant zinceda ekuzinziseni ulwakhiwo lwe-bubbles ngexesha lenkqubo yokufutha, okwenza ii-pores zangaphakathi zesitena zifane ngakumbi kwaye zibe ncinci. Ngenxa yoko, izitena ezikhaphukhaphu ezine-insulation engcono kunye namandla aphezulu ziyafumaneka.
