I-Trimethylolpropane (TMP) iyinto ebalulekile yamakhemikhali acwengekile anezicelo eziningi, ehlanganisa amasimu afana nama-alkyd resins, ama-polyurethane, ama-resins angagcwalisiwe, ama-polyester resins, kanye nokugqoka. Ngaphezu kwalokho, i-TMP isetshenziswa ekuhlanganiseni amafutha okuthambisa emoyeni, uyinki wokunyathelisa, futhi isebenza njengesithambisi sokusiza kanye nesiqinisi sokushisa sama-polyvinyl chloride (PVC) resins.
Njenge-chain extender esetshenziswa kabanzi embonini ye-resin, i-TMP ingumkhiqizo oyinhloko oqhuba ukuthuthukiswa kwezimboni komkhakha we-polyols. Isakhiwo sayo esiyingqayizivele sama-molecule siyinika indawo ephansi yokuncibilika kanye nezici ze-polyol ezifana ne-glycerol. I-TMP ayikwazi nje ukufaka esikhundleni se-glycerol ekwakhiweni kwama-resin e-alkyd kodwa futhi isebenzisana namanye ama-polyol njenge-neopentyl glycol kanye ne-pentaerythritol, okwenza izinhlobo zama-resin e-alkyd zihluke kakhulu. Lokhu kuguquguquka kuthuthukisa ukusebenza kanye nokuzivumelanisa nezimo kwemikhiqizo esekelwe ku-resin, kuqinisa indima ebalulekile ye-TMP ekuthuthukiseni ukusungula izinto ezintsha kanye nokusebenza kahle kwezicelo kuzo zonke izimboni.
Ama-resin e-alkyd alungiselelwe kusetshenziswa i-TMP abonisa ukumelana okuhle kakhulu kwe-hydrolysis, ukuzinza kwe-oxidation, ukumelana kwe-alkali, kanye nokuzinza kokushisa, okwenza afaneleke kakhulu ekukhiqizeni upende wokuphawula umgwaqo. Asetshenziswa kabanzi nasekukhiqizeni upende we-topcoat wezimoto, amafriji, imishini yokuwasha, nezinye izinto zasendlini. Ngaphezu kwalokho, i-TMP idlala indima ebalulekile ezinqubweni zokukhiqiza ama-surfactants, ama-wetting agents, ama-explosives, ama-plasticizers, amapulasitiki aqiniswe yi-fiberglass, ama-rosin esters, amafutha okugcoba ezindiza aphezulu, ama-fiber processing agents, ama-printing inks, nama-polyurethane foams, esebenza njenge-resin chain extender, i-textile assistant, kanye ne-thermal stabilizer yama-PVC resin.
Izakhi ze-TMP zithola ukusetshenziswa okubanzi emikhakheni eminingi, ezisebenza njengezinto ezixhumanisayo, izinto eziphilisayo, izinto ezixubayo, izinto ezikhiphayo, kanye nezinto ezibangela ukukhishwa kwezakhi zofuzo. Zisetshenziswa futhi ekwakhiweni kwama-electrode e-membrane ewuketshezi anokukhetha okuphezulu kwama-ion e-sodium.
I-TMP isetshenziswa kakhulu njengezinto zokusetshenziswa zokukhiqiza ama-PU curing agents, ukuhlanganisa izembozo ze-UV, kanye nokukhiqiza ama-alkyd resins asezingeni eliphezulu. E-China, ukusetshenziswa kwayo kubalwa ngaphezu kwama-70% okusetshenziswa kwasekhaya kwe-trimethylolpropane. Ngaphezu kwalokho, i-TMP idlala indima ebalulekile ekukhiqizweni kwama-polyester resins kanye ne-titanium dioxide.
I-TMP ibambe isikhundla esibalulekile ekuhlanganisweni kwama-alkyd resins aphezulu, avame ukusetshenziswa kumapende ezimoto aphezulu kanye nama-photo-curing agents okupenda noyinki. Njengoba ikhwalithi yemikhiqizo embonini yezimoto nemishini yasekhaya yaseShayina iqhubeka nokuthuthuka, isidingo sezingubo zokugqoka ezisezingeni eliphezulu sikhuphuke kakhulu. Ngesikhathi esifanayo, imithethonqubo yezemvelo eqinile iye yaqhuba ukukhula okuqhubekayo kwesidingo sama-photo-curing agents. Ngenxa yalokho, isidingo se-TMP kulindeleke ukuthi sikhule kakhulu eminyakeni ezayo.
