Trimethylolpropane (TMP) yakakosha kemikari mbishi zvinhu zvine mashandisirwo akawandisa, anotenderera minda senge alkyd resins, polyurethanes, unsaturated resins, polyester resins, uye machira. Pamusoro pezvo, TMP inoshandiswa mukugadzirwa kwemafuta ekufambisa nendege, ingi dzekudhinda, uye inoshanda semachira anobatsira uye anopisa anodzikamisa epolyvinyl chloride (PVC) resins.
Seyakashandiswa zvakanyanya cheni yekuwedzera muindasitiri yeresin, TMP chinhu chakakosha chigadzirwa chinotyaira kukwidziridzwa kwemaindasitiri kwechikamu chepolols. Yayo yakasarudzika mamorekuru chimiro inopa yakaderera kunyungudika uye glycerol-senge polyol maitiro. TMP haingogone chete kutsiva glycerol mukugadzirwa kwealkyd resins asiwo kuyananisa nemamwe ma polyols akadai neopentyl glycol uye pentaerythritol, zvichienderera mberi nekusiyanisa marudzi emaalkyd resins. Izvi zvakasiyana-siyana zvinosimudzira mashandiro uye kuchinjika kwezvigadzirwa-zvakavakirwa resin, kusimbisa basa rakakosha reTMP mukusimudzira hunyanzvi hwezvinhu uye kushanda zvakanaka kwekushandisa mumaindasitiri ese.
Alkyd resins yakagadzirwa neTMP inoratidzira yakasarudzika hydrolysis kuramba, oxidation kugadzikana, alkali kuramba, uye kugadzikana kwekupisa, zvichiita kuti ive yakakodzera kwazvo kugadzira pendi yekumaka pendi. Anoshandiswawo zvakanyanya mukugadzira pendi yetopcoat yemotokari, mafiriji, michina yekuwachisa, uye zvimwe midziyo yemumba. Pamusoro pezvo, TMP inobata basa rakakosha mukugadzira ma surfactants, wetting agents, zvinoputika, plasticizers, fiberglass-yaisimbisa mapurasitiki, rosin esters, high-grade aviation lubricant, fiber processing agents, inki dzekudhinda, uye polyurethane foams, kushanda seresin chain extender, textile axilizer, uye PVC inosimbisa.
Zvigadzirwa zveTMP zvinowana mashandisirwo akakura munzvimbo dzakawanda, anoshanda seanoyambuka maajenti, anorapa, emulsifiers, maemulsifiers, anoburitsa, uye catalysts. Ivo zvakare vanoshandirwa mukugadzira yemvura membrane electrode ine yakakwirira selectivity ye sodium ion.
TMP inonyanya kushandiswa seyakagadzirwa kugadzira PU kurapa vamiririri, synthesizing UV majasi, uye kugadzira yakakwirira-giredhi alkyd resins. MuChina, kushandiswa kwayo kunodarika makumi manomwe muzana ehuwandu hwekushandisa mudzimba kwe trimethylolpropane. Pamusoro pezvo, TMP inoita basa rakakosha mukugadzirwa kwepolyester resin uye titanium dioxide.
TMP inobata nzvimbo yepakati mukubatanidzwa kweapamusoro-ekupedzisira alkyd resin, ayo anowanzo shandiswa mumhando yepamusoro pendi yemotokari uye mapikicha ekurapa mapendi neingi. Sezvo mhando yezvigadzirwa mumaindasitiri emotokari eChina uye emidziyo yemumba iri kuramba ichikwira, kudiwa kwemachira epamusoro-soro kwakawedzera zvakanyanya. Saizvozvo, kuwedzera kuomesera mirairo yezvakatipoteredza kwakafambisa kukura kwakasimba mukudiwa kweanorapa mapikicha. Nekuda kweizvozvo, kudiwa kweTMP kunotarisirwa kuona kukura kwakanyanya mumakore anotevera.
