txo qhov kev pheej hmoo ntawm wellbore collapse,
txo qhov kev sib txhuam tsis sib haum ntawm lub laum me ntsis thiab qhov dej zoo,
thiab ncua lub neej kev pab cuam ntawm lub laum ntsis.
Cov qauv fatty acid ntawm siab roj acid tuaj yeem tsim ib qho kev ruaj khov emulsification system nrog wax thiab colloid nyob rau hauv cov roj crude,
txo cov viscosity ntawm cov roj crude.
Raws li emulsifier lossis viscosity reducer,
nws yog siv los txhim kho cov fluidity ntawm cov roj crude.
Tsis tas li ntawd, nws siv qhov chaw ua haujlwm los rhuav tshem kev ruaj ntseg ntawm cov roj emulsion,
ua kom cov dej ntws sib xyaw ua ke thiab sib haum xeeb,
accelerating kev sib cais ntawm cov roj crude thiab dej,
thiab txhim kho lub cev qhuav dej efficiency ntawm cov roj crude,
uas yog feem ntau siv nyob rau hauv cov roj crude sib sau ua ke thiab kev thauj mus los ua txuas.
2. Kev lag luam ntxhia
Cov pab pawg carboxyl ntawm cov roj acid siab tuaj yeem tsim kev sib koom tes nrog cov hlau ions ntawm qhov chaw ntawm oxidized ores
(xws li hlau ore, tsawg ntiaj teb ores, apatite),
ua rau lawv hydrophobic kom yooj yim flotation los ntawm npuas.
Nws adsorbs ntawm cov pob zeb hauv av,
Txhim khu kev khi peev xwm ntawm cov ntxhia thiab npuas kom txhim kho flotation efficiency.
3. TxheejsKev lag luam
Alkyd Resin Synthesis:
Ib qho tseem ceeb raw khoom rau kev tsim alkyd resins,
reacting nrog polyols (piv txwv li, glycerin, pentaerythritol) thiab polyacids (piv txwv li, phthalic anhydride).
Cov resins no muaj cov yeeb yaj kiab zoo- tsim cov khoom, gloss, thiab huab cua tsis kam,
dav siv nyob rau hauv architectural coatings, industrial coatings, thiab wood coatings.
Txheej Additives:
TOFA txhim kho kom qhuav nrawm, yoog raws, adhesion, thiab dej tsis kam.
Piv txwv li, ntxiv qhov tsim nyog TOFA rau cov xim latex txhim kho adhesion rau phab ntsa thiab txhuam tsis kam ntawm cov zaj duab xis txheej.
4. Roj hmab kev lag luam
Vulcanization Activator:
Raws li vulcanization activator hauv vulcanization ntawm ntuj thiab hluavtaws roj hmab,
TOFA txhawb kev cuam tshuam ntawm cov roj hmab thiab cov tshuaj vulcanizing,
accelerates vulcanization,
nce cross-link ceev ntawm vulcanizates, thiab txhim kho lub cev -cov khoom siv roj hmab
(piv txwv li, hardness, tensile zog, hnav tsis kam).
Plasticizer:
Raws li cov yas yas, TOFA txo cov roj hmab hardness thiab viscosity, txhim khu kev yooj yim thiab plasticity,
txhawb kev sib xyaw thiab molding, thiab txhim kho kev ua haujlwm txias thiab flex tsis kam ntawm cov khoom siv roj hmab.
5. Kev lag luam yas
Plasticizer thiab Lubricant:
Siv los ua plasticizer thiab lubricant hauv cov yas xws li PVC thiab PS.
Raws li ib tug plasticizer, nws txo intermolecular rog nyob rau hauv plastics,
Txhim khu kev yooj yim, ductility, thiab plasticity.
Raws li cov roj nplua nyeem, nws txo kev sib txhuam ntawm cov yas thiab cov khoom siv ua haujlwm,
txo qis zog noj, txhim kho kev ua tau zoo,
thiab txhim kho nto tiav thiab demolding cov khoom ntawm cov khoom yas.
6. Kev lag luam tshuaj txhua hnub
Surfactants:
Reacting nrog lwm cov tshuaj,
TOFA tuaj yeem tsim ntau yam surfactants
(piv txwv li, fatty acids, esters, amides),
dav siv nyob rau hauv detergents, textile auxiliaries, oilfield chemicals, thiab lwm yam.,
rau emulsification, dispersion, ntxuav, thiab foaming.
7. Kev lag luam hlau
Lubricant Additives: Raws li lubricant additives,
TOFA txhim kho lubrication, oxidation kuj, thiab xeb kuj ntawm lubricants,
txo cov neeg kho tshuab hnav thiab txuas cov cuab yeej siv lub neej.
8. Kev Lag Luam Tshuaj Hluav Taws Xob
Biofuels:
Tom qab kev ua haujlwm ntxiv,
TOFA tuaj yeem ua cov khoom siv raw rau biodiesel ntau lawm.
Los ntawm transesterification,
fatty acids hloov mus rau fatty acid methyl los yog ethyl esters los tsim biodiesel,
muab cov peev txheej txuas ntxiv mus rau lub zog hluav taws xob.
