Trimethylolpropane (TMP) waa walxo kiimiko ah oo aad u wanaagsan oo leh codsiyo ballaadhan, beero baaxad leh sida resins alkyd, polyurethane, resins aan saturated ahayn, resins polyester, iyo dahaaryo. Intaa waxaa dheer, TMP waxaa loo adeegsadaa isku dhafka saliidaha duulista, daabacaadda khadadka, waxayna u adeegtaa sidii kaaliyaha dunta iyo xasiliyaha kulaylka ee xabagta polyvinyl chloride (PVC).
Sida fidiyaha silsiladda si weyn loo isticmaalo ee warshadaha xabagta, TMP waa badeecad muhiim ah oo dhaqaajisa cusboonaysiinta warshadaha ee qaybta polyols. Qaab dhismeedkeeda molecular ee gaarka ah ayaa siinaya meel dhalaalaysa oo hooseeya iyo sifooyinka glycerol u eg. TMP kaliya ma beddeli karto glycerol ee isku-dhafka alkyd resins, laakiin sidoo kale waxay la mid tahay polyols kale sida neopentyl glycol iyo pentaerythritol, taas oo sii kordhinaysa noocyada alkyd resins. Kala duwanaanshiyahani waxa uu wanaajiyaa wax qabadka iyo la qabsiga alaabada ku salaysan resinka, iyada oo xoojinaysa doorka muhiimka ah ee TMP ee horumarinta hal-abuurka shay iyo hufnaanta codsiga guud ahaan warshadaha.
Alkyd resins ee loo diyaariyey iyadoo la adeegsanayo TMP waxay soo bandhigaysaa iska caabbinta hydrolysis heer sare ah, xasilloonida oksaydhka, caabbinta alkali, iyo xasilloonida kulaylka, taasoo ka dhigaysa inay aad ugu habboon yihiin soo saarista rinjiyeyaasha calaamadaynta waddooyinka. Waxa kale oo si weyn loogu isticmaalaa soo saarista rinjiga koodhka ee baabuurta, talaajadaha, mishiinada dharka, iyo qalabka kale ee guriga. Intaa waxaa dheer, TMP waxay door muhiim ah ka ciyaartaa hababka wax soo saarka ee surfactants, wakiilada qoynta, walxaha qarxa, balaastikada, balaastikada lagu xoojiyay fiberglass, rosin esters, saliidaha duulimaadka ee heerka sare ah, wakiilada farsamaynta fiber, khadadka daabacaadda, iyo foams polyurethane, oo u adeegaya sidii silsilad xashiishad ah, qalabaynta PVC ee adkaysiga.
Soosaarayaasha TMP waxay ka helaan codsiyo ballaaran oo dhinacyo badan leh, oo u shaqeeya sidii wakiilo isku xira, wakiilada daaweeya, emulsifiers, wakiilada sii daynta, iyo kicinta. Waxa kale oo ay ka shaqeeyaan samaynta electrodes xuubka dareere leh xulashada sare ee ion sodium.
TMP waxaa ugu horrayn loo adeegsadaa walxo cayriin ah oo loogu talagalay soo saarista wakiilada daawaynta PU, samaynta dahaarka UV, iyo soo saarista resins-alkyd heer sare ah. Shiinaha, isticmaalkeeda ayaa ka badan 70% wadarta guud ee isticmaalka gudaha ee trimethylolpropane. Intaa waxaa dheer, TMP waxay door muhiim ah ka ciyaartaa soo saarista resins polyester iyo titanium dioxide.
TMP waxay ku haysaa meel dhexe oo isku xidhka resins-dhamaadka sare ee alkyd, kuwaas oo sida caadiga ah loo isticmaalo rinji baabuurta qaaliga ah iyo wakiilada sawir-qaadista ee rinjiga iyo khadadka. Maaddaama tayada alaabooyinka warshadaha baabuurta iyo qalabka guryaha ee Shiinaha ay sii wadaan inay soo hagaagaan, baahida loo qabo dahaarka heerka sare ayaa si aad ah kor ugu kacay. Isla markaa, xeerarka deegaanka ee sii adkaanaya ayaa horseeday kobaca joogtada ah ee baahida wakiilada sawir-qaadista. Sidaa darteed, baahida loo qabo TMP waxaa la filayaa inay la kulmaan kobac la taaban karo sanadaha soo socda.
