Trimethylolpropane (TMP) chinhu chakakosha chemakemikari ane mashandisirwo akawanda, chinosanganisira ma alkyd resins, polyurethanes, unsaturated resins, polyester resins, uye coatings. Pamusoro pezvo, TMP inoshandiswa mukugadzira mafuta ekufambisa ndege, inki dzekudhinda, uye inoshanda semubatsiri wejira uye stabilizer ye polyvinyl chloride (PVC) resins.
Semuchina wekuwedzera cheni unoshandiswa zvakanyanya muindasitiri ye resin, TMP chigadzirwa chakakosha chinotungamira kuvandudzwa kwemaindasitiri e polyols. Maumbirwo ayo akasiyana emamorekuru anoita kuti ive nenzvimbo yakaderera yekunyunguduka uye hunhu hwakafanana ne glycerol. TMP haingogone kutsiva glycerol chete mukugadzirwa kwe alkyd resin asiwo inoshanda pamwe chete nemamwe ma polyol akadai se neopentyl glycol ne pentaerythritol, zvichiwedzera kusiyanisa mhando dze alkyd resin. Kuchinja-chinja uku kunosimudzira mashandiro uye kuchinjika kwezvigadzirwa zvakagadzirwa ne resin, zvichisimbisa basa guru reTMP mukusimudzira hunyanzvi hwezvinhu uye kushanda zvakanaka kwekushandisa mumaindasitiri.
Maresin eAlkyd akagadzirwa achishandisa TMP anoratidza kusimba kwehydrolysis, kusimba kweoxidation, kusimba kwealkali, uye kusimba kwekupisa, zvichiita kuti akwanise kugadzira pendi dze road marking. Anoshandiswawo zvakanyanya mukugadzira pendi dze topcoat dzemotokari, mafiriji, michina yekuwachisa, nezvimwe midziyo yemumba. Uyezve, TMP inoita basa rakakosha mukugadzirwa kwema surfactants, wetting agents, zvinoputika, plasticizers, fiberglass-reinforced plastics, rosin esters, high-grade aviation lubricants, fiber processing agents, printing inks, uye polyurethane foams, inoshanda se resin chain extender, textile assistant, uye thermal stabilizer yePVC resin.
Zvigadzirwa zveTMP zvinoshandiswa zvakanyanya munzvimbo dzakasiyana-siyana, zvinoshanda se crosslinking agents, curing agents, emulsifiers, release agents, uye catalysts. Zvinoshandiswawo mukugadzira liquid membrane electrodes dzine sarudzo yakakura ye sodium ions.
TMP inonyanya kushandiswa sezvinhu zvekugadzira PU curing agents, kugadzira maUV coatings, uye kugadzira ma alkyd resins emhando yepamusoro. MuChina, kushandiswa kwayo kunodarika 70% yehuwandu hwese hwe trimethylolpropane inodyiwa pamba. Pamusoro pezvo, TMP ine basa rakakosha mukugadzirwa kwe polyester resins uye titanium dioxide.
TMP ine chinzvimbo chikuru mukugadzirwa kwema alkyd resins emhando yepamusoro, ayo anowanzo shandiswa mumapendi emotokari epamusoro uye ma photo-curing agents emapendi ne inki. Sezvo mhando yezvigadzirwa mumaindasitiri emotokari nemidziyo yemumba muChina iri kuramba ichivandudzika, kudiwa kwema coatings emhando yepamusoro kwakawedzera zvakanyanya. Panguva imwe chete, mitemo yakasimba yezvakatipoteredza yave ichikurudzira kukura kwakasimba mukudiwa kwema photo-curing agents. Nekuda kweizvozvo, kudiwa kweTMP kunotarisirwa kukura zvakanyanya mumakore anotevera.
