I-Trimethylolpropane (TMP) iyinto ebalulekile yamakhemikhali eluhlaza futhi isetshenziswa kabanzi, izinkambu ezinwebekayo njengama-alkyd resins, ama-polyurethanes, ama-resin angasetshenzisiwe, ama-polyester resins, nama-coatings. Ukwengeza, i-TMP isetshenziswa ekuhlanganiseni izithambisi zezindiza, oyinki bokuphrinta, futhi isebenza njengesizinzi sendwangu nesigxivizo esishisayo sezinhlaka ze-polyvinyl chloride (PVC).
Njenge-chain extender esetshenziswa kabanzi embonini ye-resin, i-TMP ingumkhiqizo obalulekile oqhuba ukuthuthukiswa kwezimboni zomkhakha we-polyols. Isakhiwo sayo samangqamuzana esiyingqayizivele siyinikeza indawo ephansi yokuncibilika kanye nezici ze-polyol ezifana ne-glycerol. I-TMP ayikwazi ukufaka esikhundleni se-glycerol kuphela ekuhlanganisweni kwama-alkyd resins kodwa futhi isebenzisana namanye ama-polyols afana ne-neopenyl glycol ne-pentaerythritol, iqhubeke nokuhlukanisa izinhlobo zama-alkyd resins. Lokhu kuguquguquka kuthuthukisa ukusebenza kanye nokuvumelana nezimo kwemikhiqizo esekelwe ku-resin, kuqinise indima ebalulekile ye-TMP ekuthuthukiseni ukusungulwa kwezinto ezintsha nokusebenza kahle kwezinhlelo zokusebenza kuzo zonke izimboni.
Ama-alkyd resins alungiselelwe kusetshenziswa i-TMP abonisa ukumelana ne-hydrolysis okuvelele, ukuzinza kwe-oxidation, ukumelana ne-alkali, nokuzinza kokushisa, okuwenza afaneleke kakhulu ukukhiqiza opende bokumaka bomgwaqo. Abuye asetshenziswe kabanzi ekwenzeni upende we-topcoat wezimoto, iziqandisi, imishini yokuwasha, nezinye izinto zasendlini. Ngaphezu kwalokho, i-TMP idlala indima ebalulekile ekukhiqizeni ama-surfactants, ama-wetting agents, iziqhumane, ama-plasticizers, amapulasitiki aqiniswe nge-fiberglass, i-rosin esters, izinto zokuthambisa zezindiza ezisezingeni eliphakeme, ama-fiber processing agents, oyinki bokuphrinta, kanye namagwebu e-polyurethane, asebenza njenge-resin chain extender, i-textile axiliary for the PVC stabilizer.
Okuphuma kokunye kwe-TMP kuthola izinhlelo zokusebenza ezibanzi kuzo zonke izinkambu eziningi, zisebenza njengama-ejenti axhumanisayo, ama-ejenti okwelapha, ama-emulsifiers, ama-ejenti akhululayo, nama-catalysts. Baphinde baqashwe ekwakhiweni kwama-electrode olwelwesi oluwuketshezi ngokukhetha okuphezulu kwama-ion sodium.
I-TMP isetshenziswa ngokuyinhloko njengempahla eluhlaza ekukhiqizeni ama-ejenti okwelapha e-PU, ukuhlanganisa ama-UV okunamathelayo, nokwenza ama-alkyd resins asezingeni eliphezulu. E-China, ukusetshenziswa kwayo kubalwa ngaphezu kwama-70% wengqikithi yokusetshenziswa kwasekhaya kwe-trimethylolpropane. Ukwengeza, i-TMP idlala indima ebalulekile ekukhiqizeni ama-polyester resins kanye ne-titanium dioxide.
I-TMP ibambe indawo emaphakathi ekuhlanganisweni kwama-alkyd resins asezingeni eliphezulu, avame ukusetshenziswa kumapende ezimoto aphambili kanye nama-ejenti wokulapha izithombe opende noyinki. Njengoba izinga lemikhiqizo ezimbonini zezimoto nezasekhaya zaseChina liqhubeka nokuba ngcono, isidingo sokumboza sezinga eliphezulu sikhule kakhulu. Ngasikhathi sinye, imithethonqubo eqinile yezemvelo iqhubekisele phambili ukukhula okuqhubekayo kwesidingo sama-ejenti alapha izithombe. Ngenxa yalokho, isidingo se-TMP kulindeleke ukuthi sikhule kakhulu eminyakeni ezayo.
