Cov feem ntau siv surfactants yog cov molecular hnyav sib xyaw nrog txoj kev molecular hnyav ntawm ntau pua. Nrog ntau cov ntsiab lus kub xws li kev tshawb fawb ua kom zoo dua ntawm cov khoom siv yeeb yaj kiab, thiab lwm yam, muaj ntau yam kev xav tau rau surfactants. Surfactant Polymer cov tebchaw tau dhau los ua kev saib xyuas.
Cov tshuaj nrog lub cev hnyav ntawm ob peb txhiab lossis ntau dua thiab cov dej num sib tw feem ntau hu ua cov molecular hnyav surfactants. Zoo ib yam li cov surfactants zoo ib yam, tsis muaj cov qauv txheej txheem rau cov polymer sursfactants. Raws li kev faib tawm ntawm cov roj av qis surfactants raws li lawv ionicity hauv dej, lawv tuaj yeem faib rau hauv anionic, cationic, thiab nonionic hom. Raws li kev daws teeb meem txawm tsim nyob rau hauv kev daws teeb meem, nws tuaj yeem faib ua xab npum thiab dej-soluble polymer surt.
Polyssap
Feem ntau ntawm cov xab npum tau raug them, zoo ib yam li polyelectrolytes. Qhov tseeb, cov xab npum feem ntau yog cov khoom lag luam ntawm hydrophobic hloov ntawm polyelectric thiab feem ntau tsis muaj insoluble hauv dej. Tam sim no muaj ntau hom synaps (qhov twg r sawv cev ntev-saw alkyl):
Dej soluble polymer surfactant
Polymer surfactants uas tsis ua micelles hauv kev daws teeb meem yog feem ntau dej-soluble polymer solfactants. Raws li lawv qhov chaw, lawv tuaj yeem muab faib ua peb pawg: ntuj tsim hluavtaws, thiab hluavtaws polymer sursidants.
Lub ntuj polymers xws li ntau tsob ntoo pos hniav, hmoov txhuv nplej siab, microbial fermented polysaccharides, thiab lwm yam;
Synthetic polymers yog ntau cov polymers tau los ntawm cov hmoov txhuv nplej siab ntawm cov hmoov txhuv nplej siab, thiab cov protein, xws li cationic hmoov, metryl cellulose, thiab lwm yam;
Cov hluavtaws hluavtaws tau los ntawm polymerizing monomers tau los ntawm petrochemicals, xws li polyacrylamide derivatives, polyacrylic acid, thiab lwm yam.
Kev faib tawm polymer sursfactants
Raws li cov ionicity nyob rau hauv dej, lawv tuaj yeem faib rau anionic, cationic, zwitterionic, thiab tsis-ionic hom.
Anionic polymer surfactant
(1) Raug cov roj ntsha acid hom polymers xws li polyacrylic acid thiab nws cov copylic acid thiab nws cov tub luam yeeb, Acrylic acid thiab cov khoom lag luam sapolymers, thiab lawv cov khoom lag luam saponified.
(2) Raug polymers ntawm sulfate ester hom muaj xws li:
(3) sulfonic acid hom
Qee cov sulfonated polystyresronic acid forticdehyde condensehyde condensehyde kuj yog a sulponic acid hom polymer surfactant. Raug sulfonic acid Raws polymer sursfactants xws li:
Cationic polymer surtant
Amine ntsev lossis polyamines xws li polyethyleneimine, polyvinylprolidone, polinaleimide, thiab lawv cov derivatives. Raug polymers muaj xws li:
(2) Quaternary Ammonium ntsev
Xws li quermized polyacrylamide, polydimethylamine epichlorohydrapan, thiab lwm yam. Cov neeg sawv cev muaj xws li:
Amphoteric polymer surfactant
Cov ntau yam tseem ceeb suav nrog Acrylic Vinyl pyridine Copolymer, Acrylic Acid, Cationic Acrylic Ester Copolymer, thiab lwm yam, xws li:
Tsis ionic polymer sursidants
Cov dej cawv uas suav nrog cov dej cawv polyvinyl thiab nws cov khoom lag luam lossis cov txiv neej muaj kuab oxide, polyethylene oxide, polyethylene phenolic resin, amino resin, thiab lwm yam.
Cov qauv thiab cov khoom ntawm polymer sursfactants
Cov kev ua si ntawm polymer surfactants nyob ntawm morphology ntawm macromolecules hauv kev daws teeb meem, thiab txheeb ze molecular hnyav ntawm macromolecules.
Thaiv hom surfactant
Ntau thaiv hydrophobic ntu tau faib rau ntawm macrophobic ntu (kev sib sau ua ke ntawm hydrophobic ntu) lossis kev sib xyaw ua ke)
Twb puab surfactant
Txhuam cov surfactants muaj qhov zoo ntawm kev npaj yooj yim thiab ntau yam ntau yam. Surfactants tuaj yeem tau los ntawm homopolymerization lossis copolymerization ntawm ob qho tib si sexes thiab amphiphilic monomers. Ua raws li txoj haujlwm ntawm hydrophobic thiab hydrophilic pawg, lawv nthuav tawm cov qauv siv tshuaj sib txawv.
Vim tias muaj cov pab pawg hydrophricic ntawm sab saw hlau, kev sib sau ua ke thiab koom haum ntawm cov ntu hydrophobic yog tabkaum. Txawm hais tias nyob rau hauv twb tau tsim micelles, piv rau kev nruj me ntsis ntim Mickelles, yog muaj ntau cov khoom siv dej ntau; Lub caij no, vim kev teeb tsa, amphiphilic ceg tuaj yeem yuav cuam tshuam cov kab ke ntawm methylene thiab methylene pawg, tso cai rau lawv koom nrog kev tshaj tawm kev sib cais.
Kev tshawb fawb tau pom tias txhua yam uas nce cov roj av ntawm molecular ntawm macromolecules nyob rau hauv kev daws teeb meem thiab tuaj yeem txhim kho cov kev ua si ntawm cov polymers.
Daim ntawv thov polymer sursfactants
DAIM NTAWV THOV IN TEXTILE Luam Ntawv Thiab Dyeing Kev Lag Luam
Polyether Raws Cai Feem ntau yog siv los ua cov tshuaj ntxuav ua npuas dej tsawg, tshuaj tiv thaiv kab mob, luam tawm thiab cov neeg sawv cev. Kev haus dej cawv thiab lwm yam macromolecular tau siv dav ua cov tuab thiab tiv thaiv kev tiv thaiv cov luam ntawv tshuaj pleev thiab zas cov neeg ua haujlwm; Cellulose derivatives xws li carboxymethyl cellulose tau siv nyob rau hauv detergents yog anti fouling cov neeg sawv cev; Lignosulfonate thiab Phenolic Sulfonate tau siv raws li cov neeg tsis txaus siab rau insoluble dyes.
