I-Trimethylolpropane/TMP Cas77-99-6

Inkcazelo emfutshane:

I-Trimethylolpropane, eyaziwa ngokuba yi-TMP, i-organic compound kunye ne-chemical formula C6H14O3.Yikristale eqinileyo emhlophe enyibilikayo kakhulu emanzini kwaye inozinzo olubalaseleyo lwe-thermal kunye neekhemikhali.I-TMP iveliswa ikakhulu yi-esterification ye-formaldehyde kunye ne-intermediate compound trimethylolpropionaldehyde (TMPA).Le khompawundi eguquguqukayo ineempawu ezizodwa ezenza ukuba ibe yimfuneko kumashishini ahlukeneyo.

Isicelo

- Iingubo kunye ne-adhesives: I-TMP iyona nto iphambili kwimveliso yomgangatho ophezulu kunye ne-adhesives.Iimpawu zayo ezibalaseleyo zokwenza ifilimu, ukuchasana kwe-yellowing, kunye nokuhambelana noluhlu olubanzi lwee-resin kwenza kube yinto efanelekileyo kwezi zicelo.

- I-Polyurethane (PU) i-foams: I-TMP yinto ebalulekileyo ye-polyol kwimveliso ye-PU foams yefenitshala, i-automotive yangaphakathi kunye ne-insulation.Inceda ukunika uzinzo oluphezulu lwe-foam, ukumelana nomlilo kunye nokuqina.

- Izithambisi zokwenziwa: Ngenxa yokuzinza kweekhemikhali kunye neempawu zokuthambisa, i-TMP isetyenziswa kakhulu ekuveliseni izithambiso zokwenziwa, iqinisekisa ukusebenza kakuhle kunye nobomi obude boomatshini.

- I-Alkyd resins: I-TMP iyinxalenye ebalulekileyo ye-synthetic alkyd resins, esetyenziswa ngokubanzi kwimveliso yeengubo, i-varnishes kunye neepende.Ikhono layo lokuphucula ukuqina, ukugcinwa kwegloss kunye neempawu zokomisa kwenza kube yinto ebalulekileyo kwezi zicelo.

Ukuququmbela

Isishwankathelo, i-trimethylolpropane (i-TMP) yikhompawundi eguquguqukayo kunye nebalulekileyo edlala indima ebalulekileyo kumashishini ahlukeneyo afana ne-coatings, i-adhesives, i-polyurethane foams, i-lubricants kunye ne-alkyd resins.Iipropati zayo ezigqwesileyo kunye noluhlu olubanzi lwezicelo zenza i-TMP ibe yinto eyimfuneko kwiimveliso ezininzi.

Njengomthengisi othembekileyo, siqinisekisa umgangatho ophezulu kunye nokuhambelana kwe-Trimethylolpropane, ekuvumela ukuba ufezekise iziphumo ezingcono kakhulu.Nceda uzive ukhululekile ukuqhagamshelana nathi ngolwazi oluthe kratya okanye wenze iodolo.Sijonge ukukubonelela nge-TMP ephezulu kunye nokuhlangabezana nazo zonke iimfuno zakho zemichiza.
