I-Trimethylolpropane (TMP) sisixhobo esibalulekileyo sekhemikhali esicocekileyo esisetyenziswa kakhulu, sigubungela iindawo ezifana nee-alkyd resins, ii-polyurethanes, ii-unsaturated resins, ii-polyester resins, kunye neengubo. Ukongeza, i-TMP isetyenziswa ekuhlanganiseni ii-lubricants zeenqwelo moya, ii-inki zokuprinta, kwaye isebenza njengesibambisi-ndlela selaphu kunye nesiqinisi sobushushu kwii-polyvinyl chloride (PVC) resins.
Njengesixhobo sokwandisa iintambo esisetyenziswa kakhulu kwishishini le-resin, i-TMP yimveliso ephambili eqhuba ukuphuculwa kweshishini le-polyols. Ulwakhiwo lwayo olukhethekileyo lwe-molecular luyinika indawo ephantsi yokunyibilika kunye neempawu ze-polyol ezifana ne-glycerol. I-TMP ayinakuthatha indawo ye-glycerol kuphela ekuhlanganisweni kwee-resin ze-alkyd kodwa ikwasebenzisana nezinye ii-polyols ezifana ne-neopentyl glycol kunye ne-pentaerythritol, nto leyo eyahlulahlula iintlobo zee-resin ze-alkyd. Oku kuguquguquka kuphucula ukusebenza kunye nokuguquguquka kweemveliso ezisekelwe kwi-resin, kuqinisa indima ebalulekileyo ye-TMP ekuphuculeni ubuchule bezinto kunye nokusebenza kakuhle kwesicelo kumashishini onke.
Ii-resin ze-alkyd ezilungiselelwe kusetyenziswa i-TMP zibonisa ukumelana okubalaseleyo kwe-hydrolysis, ukuzinza kwe-oxidation, ukumelana ne-alkali, kunye nokuzinza kobushushu, okwenza ukuba zifaneleke kakhulu ukuvelisa iipeyinti zokuphawula indlela. Zikwasetyenziswa kakhulu ekuveliseni iipeyinti ze-topcoat zeemoto, iifriji, oomatshini bokuhlamba, kunye nezinye izixhobo zasekhaya. Ngaphezu koko, i-TMP idlala indima ebalulekileyo kwiinkqubo zemveliso yee-surfactants, ii-agents zokumanzisa, ii-explosives, ii-plasticizers, iiplastiki eziqinisiweyo ze-fiberglass, ii-esters ze-rosin, ii-lubricants zeenqwelo moya eziphezulu, ii-agents zokucubungula i-fiber, ii-inki zokushicilela, kunye nee-polyurethane foams, zisebenza njenge-resin chain extender, i-textile assistant, kunye ne-thermal stabilizer kwii-resin ze-PVC.
Izinto eziphuma kwi-TMP zifumana ukusetyenziswa okubanzi kwiindawo ezininzi, zisebenza njengee-agents ezidibanisayo, ii-agents eziphilisayo, ii-emulsifiers, ii-agents zokukhulula, kunye nee-catalysts. Zikwasetyenziswa ekwenziweni kwee-electrodes ze-membrane yolwelo ezinokukhetha okuphezulu kwee-ion ze-sodium.
I-TMP isetyenziswa kakhulu njengezinto ezisetyenziswa ekuveliseni ii-PU curing agents, ekuhlanganiseni ii-UV coatings, nasekuveliseni ii-alkyd resins ezikumgangatho ophezulu. E-China, ukusetyenziswa kwayo kungaphezulu kwe-70% yokusetyenziswa kwe-trimethylolpropane ekhaya. Ukongeza, i-TMP idlala indima ebalulekileyo ekuveliseni ii-polyester resins kunye ne-titanium dioxide.
I-TMP ibambe indawo ephambili ekuqulunqweni kwee-alkyd resins eziphezulu, ezisetyenziswa kakhulu kwiipeyinti zeemoto eziphambili kunye nee-photo-curing agents zepeyinti kunye nee-inki. Njengoko umgangatho weemveliso kwimizi-mveliso yeemoto kunye nezixhobo zasekhaya zaseTshayina uqhubeka uphucuka, imfuno yeengubo eziphezulu inyuke kakhulu. Kwangaxeshanye, imithetho engqongqo yokusingqongileyo iqhube ukukhula okuqhubekayo kwimfuno yee-photo-curing agents. Ngenxa yoko, imfuno ye-TMP kulindeleke ukuba ikhule kakhulu kwiminyaka ezayo.
