Trimethylolpropane/TMP Cas77-99-6

Kufotokozera Kwachidule:

Trimethylolpropane, yomwe imadziwikanso kuti TMP, ndi organic pawiri ndi mankhwala chilinganizo C6H14O3.Ndi kristalo yoyera yoyera yomwe imasungunuka kwambiri m'madzi ndipo imakhala ndi kukhazikika kwamafuta ndi mankhwala.TMP imapangidwa makamaka ndi esterification ya formaldehyde yokhala ndi trimethylolpropionaldehyde yapakatikati (TMPA).Gulu losunthikali lili ndi zinthu zapadera zomwe zimapangitsa kuti zikhale zofunikira m'mafakitale osiyanasiyana.

1. Thupi ndi mankhwala:

- Maonekedwe: ma crystalline oyera olimba

- Kulemera kwa mamolekyu: 134.17 g/mol

- Malo osungunuka: 57-59 ° C

- Malo otentha: 204-206 ° C

- Kachulukidwe: 1.183 g/cm3

- Kusungunuka: kusungunuka kwambiri m'madzi

- Fungo: lopanda fungo

- Kung'anima: 233-238°C

Kugwiritsa ntchito

- Zopaka ndi zomatira: TMP ndiye chinthu chofunikira kwambiri popanga zokutira ndi zomatira zapamwamba kwambiri.Mawonekedwe ake abwino kwambiri opangira mafilimu, kukana kwachikasu, komanso kuyanjana ndi ma resin osiyanasiyana kumapangitsa kuti ikhale yabwino kwa izi.

- Polyurethane (PU) thovu: TMP ndi gawo lofunikira la polyol popanga thovu la PU la mipando, zamkati zamagalimoto ndi kutchinjiriza.Zimathandizira kukhazikika kwa chithovu chapamwamba, kukana moto komanso kulimba.

- Mafuta opangira: Chifukwa cha kukhazikika kwake kwamankhwala komanso mafuta, TMP imagwiritsidwa ntchito kwambiri popanga mafuta opangira, kuwonetsetsa kuti ikugwira ntchito bwino komanso moyo wautali wamakina.

- Alkyd resins: TMP ndi gawo lofunikira la ma alkyd resins, omwe amagwiritsidwa ntchito kwambiri popanga zokutira, ma varnish ndi utoto.Kuthekera kwake kukulitsa kukhazikika, kusungika kwa gloss ndi kuyanika kumapangitsa kuti ikhale yofunika kwambiri pakugwiritsa ntchito izi.

Pomaliza

Mwachidule, trimethylolpropane (TMP) ndi yosunthika komanso yofunika kwambiri yomwe imagwira ntchito yofunika kwambiri m'mafakitale osiyanasiyana monga zokutira, zomatira, thovu la polyurethane, mafuta odzola ndi ma alkyd resins.Katundu wake wabwino kwambiri komanso magwiridwe antchito osiyanasiyana amapangitsa TMP kukhala chinthu chofunikira kwambiri pazinthu zambiri.

Monga ogulitsa odalirika, timatsimikizira kuti Trimethylolpropane yapamwamba kwambiri komanso yosasinthasintha, kukuthandizani kuti mupeze zotsatira zabwino kwambiri.Chonde khalani omasuka kutilankhula nafe kuti mumve zambiri kapena kuyitanitsa.Tikuyembekezera kukupatsirani TMP yapamwamba kwambiri ndikukwaniritsa zosowa zanu zonse zama mankhwala.
