Application

-Kupfeka uye zvinonamira: TMP chinhu chakakosha mukugadzirwa kwemhando yepamusoro yekupfeka uye zvinonamira.Iyo yakanakisa firimu-inogadzira zvimiro, yellowing kuramba, uye kuenderana neyakasiyana siyana resin inoita kuti ive yakakodzera kune izvi zvikumbiro.

- Polyurethane (PU) furo: TMP chinhu chakakosha che polyol mukugadzirwa kwePU foam yefenicha, zvemukati zvemotokari uye kuvharisa.Inobatsira kupa kugadzikana kwefuro yepamusoro, kudzivirira moto uye kusimba.

-Synthetic lubricant: Nekuda kwekugadzikana kwayo kwemakemikari uye zvimiro zvekuzora, TMP inoshandiswa zvakanyanya mukugadzirwa kwemafuta ekuzora, kuve nechokwadi chekuita kwakanyanya uye hupenyu hurefu hwemuchina.

- Alkyd resins: TMP chinhu chakakosha chekugadzira alkyd resins, inoshandiswa zvakanyanya mukugadzira machira, varnish uye pendi.Kugona kwayo kuwedzera kusimba, gloss kuchengetedza uye kuomesa zvimiro zvinoita kuti ive chinhu chakakosha mukushandisa uku.

Mukupedzisa

Muchidimbu, trimethylolpropane (TMP) isanganiswa uye yakakosha komisheni inoita basa rakakosha mumaindasitiri akasiyana senge machira, zvinonamira, polyurethane foams, lubricant uye alkyd resins.Hunhu hwayo hwakanakisa uye huwandu hwakasiyana hwekushandisa hunoita kuti TMP ive chinhu chakakosha muzvigadzirwa zvakawanda.

Semutengesi akavimbika, tinova nechokwadi chemhando yepamusoro uye kuwirirana kweTrimethylolpropane, zvichiita kuti iwe uwane zvakanakisa mhedzisiro.Ndapota inzwa wakasununguka kutibata nesu kuti uwane rumwe ruzivo kana kuisa odha.Isu tinotarisira kukupa iwe yepamusoro-notch TMP uye kusangana nezvose zvaunoda makemikari.
