Trimethylolpropane (mu magambo ahinnye yitwa TMP)

Trimethylolpropane (TMP) nigikoresho cyingenzi cyibikoresho bya shimi bifite ibikoresho byinshi, imirima ikwirakwizwa nka alkyd resin, polyurethanes, ibisigazwa bituzuye, ibisigazwa bya polyester, hamwe na coatings. Byongeye kandi, TMP ikoreshwa muguhuza amavuta yo mu ndege, gucapa wino, kandi ikora nk'imyenda ifasha hamwe na stabilisateur yumuriro wa polyvinyl chloride (PVC).

Nkurunigi rukoreshwa cyane mugukwirakwiza inganda, TMP nigicuruzwa cyingenzi gitera kuzamura inganda zumurenge wa polyoli. Imiterere yihariye ya molekile itanga ingingo yo gushonga hasi hamwe na glycerol imeze nka polyol. TMP ntishobora gusimbuza glycerol gusa muri synthesis ya alkyd resin ahubwo ishobora no guhuza izindi polyoli nka neopentyl glycol na pentaerythritol, bikarushaho gutandukanya ubwoko bwibisigazwa bya alkyd. Ubu buryo bwinshi buteza imbere imikorere no guhuza ibicuruzwa bishingiye ku bisigazwa, bigashimangira uruhare rukomeye rwa TMP mu guteza imbere udushya no gukoresha neza inganda.

Ibisigarira bya Alkyd byateguwe hakoreshejwe TMP byerekana imbaraga zidasanzwe za hydrolysis, okiside itajegajega, kurwanya alkali, hamwe nubushyuhe bwumuriro, bigatuma bikenerwa cyane kubyara amarangi yumuhanda. Zikoreshwa kandi cyane mugukora amarangi ya topcoat yimodoka, firigo, imashini imesa, nibindi bikoresho byo murugo. Byongeye kandi, TMP igira uruhare runini mugikorwa cyo gukora ibintu bya surfactants, ibikoresho byo guhanagura, ibisasu, plastike, plastike ikomezwa na fiberglass, ester ya rosin, amavuta yo mu kirere yo mu rwego rwo hejuru, ibikoresho byo gutunganya fibre, inkingi zo gucapa, hamwe na polyurethane ifuro, ikora nk'iyaguka rya resin, umufasha w’imyenda, hamwe na stabilisateur ya PVC.

Inkomoko ya TMP isanga porogaramu nini mubice byinshi, ikora nkibikoresho bihuza, imiti ikiza, emulisiferi, imiti irekura, hamwe na catalizator. Bakoreshwa kandi muguhimba amashanyarazi ya electrode ya elegitoronike hamwe no guhitamo cyane kuri sodium ion.

TMP ikoreshwa cyane nkibikoresho fatizo byo gukora imiti ikiza ya PU, guhuza ibara rya UV, no gukora ibisigazwa byo mu rwego rwo hejuru. Mu Bushinwa, ibyo ikoresha bingana na 70% by’imikoreshereze y’imbere mu gihugu ya trimethylolpropane. Byongeye kandi, TMP igira uruhare runini mukubyara polyester na dioxyde de titanium.

TMP ifite umwanya wingenzi muri synthesis ya end-end ya alkyd resin, zikoreshwa cyane mugushushanya amarangi yimodoka hamwe nibikoresho bikiza amafoto kubirangi na wino. Mu gihe ubwiza bw’ibicuruzwa mu nganda zikoresha amamodoka n’ibikoresho byo mu rugo bikomeje kwiyongera, icyifuzo cy’imyenda yo mu rwego rwo hejuru cyiyongereye cyane. Hamwe na hamwe, amategeko y’ibidukikije agenda arushaho gukomera yatumye iterambere ryiyongera mu gukenera imiti ikiza. Kubera iyo mpamvu, icyifuzo cya TMP giteganijwe kuzamuka cyane mumyaka iri imbere.
