Intangiriro
2,2-Bis (hydroxymethyl) 1,3-propanediol, izwi kandi nka TMP cyangwa trimethylalkyl triol, ni ifumbire mvaruganda. Ibikurikira nintangiriro yumutungo wacyo, imikoreshereze, uburyo bwo gukora namakuru yumutekano:
Ubwiza:
- Kugaragara: 2,2-Bis (hydroxymethyl) 1,3-propanediol ni ibara ritagira ibara ryumuhondo wijimye.
- Gukemura: Irashobora gushonga mumazi hamwe nudukoko twinshi twa organic nka ethers, alcool, na ketone.
- Guhagarara: Birahagaze neza mubihe bisanzwe bya okiside, ariko bizangirika mubushyuhe bwinshi hamwe na acide.
Koresha:
- Ibintu shingiro: 2,2-bis (hydroxymethyl) 1,3-propanediol ni imiti igereranya n’ibikoresho fatizo fatizo, bishobora gukoreshwa muguhuza ibindi bintu kama.
- Flame retardant: Irashobora gukoreshwa nka retardant ya flame muguhuza ibikoresho bya polymer polyurea hamwe na polymer.
- Gutegura ibimera bya ester: 2,2-Bis (hydroxymethyl) 1,3-propanediol irashobora gukoreshwa mugutegura ibice bya ester, nka polyol polyester na polyester polymers.
Uburyo:
- Irashobora gutegurwa na reaction ya reaction ya formaldehyde na methanol: icya mbere, formaldehyde na methanol bifatwa na methanol mugihe cya alkaline kugirango bibe methanol hydroxyformaldehyde, hanyuma 2,2-bis (hydroxymethyl) 1,3-propanediol ikorwa na reaction ya bimolecules na methanol mubihe bya acide.
Amakuru yumutekano:
- 2,2-Bis (hydroxymethyl) 1,3-propanediol muri rusange ifite umutekano mugihe gisanzwe cyo gukoresha, ariko hagomba kuvugwa ibi bikurikira:
- Birashobora kuba byanduye: Ubucuruzi buraboneka 2,2-bis (hydroxymethyl) 1,3-propanediol irashobora kuba irimo imyanda mike cyangwa umwanda, bityo rero witondere kugenzura ikirango no kugura ibicuruzwa kubatanga ibicuruzwa byizewe mugihe ubikoresha.
- Kurakara uruhu: Birashobora kugira ingaruka mbi kuruhu n'amaso, kandi hagomba gufatwa ingamba zikenewe z'umutekano mugihe zikozeho, nko kwambara uturindantoki twa chimique na gogles, no kwirinda guhura.
- Imiterere yububiko: Ikomatanyirizo rigomba kubikwa ahantu hijimye, humye kandi gahumeka neza, kure yumuriro, ubushyuhe bwinshi, na okiside.
- Uburozi: 2,2-Bis (hydroxymethyl) 1,3-propanediol ntabwo ari uburozi, ariko igomba kwirinda kwirinda gufata cyangwa guhumeka.
