Ma surfactants omwe amagwiritsidwa ntchito kwambiri ndi ma cell ang'onoang'ono olemera omwe amakhala ndi mamolekyulu olemera mazana angapo. Ndi mitu yambiri yotentha monga kuwonjezereka kwa kuchira kwa mafuta Kufufuza mozama pa zonyamulira mankhwala ndi kumasulidwa koyendetsedwa, kuyerekezera kwachilengedwe, filimu ya polima LB, zipangizo zachipatala za polima (anticoagulant), mafuta odzola polymerization, ndi zina zotero, zakhala zikuchulukirachulukira komanso zofunikira zogwirira ntchito kwa owonjezera. Zopangidwa ndi ma polima a Surfactant zakhala zomwe zikuyang'ana kwambiri.
Zinthu zolemera masauzande angapo kapena kupitilira apo komanso zochitika zapamtunda nthawi zambiri zimatchedwa high molecular weight surfactants. Mofanana ndi ma surfactants wamba, palibe dongosolo lokhazikika la ma polymer surfactants. Malinga ndi gulu la otsika ma surfactants olemera a ma molekyulu kutengera umunthu wawo m'madzi, amatha kugawidwa mu mitundu ya anionic, cationic, zwitterionic, ndi nonionic. Kutengera ngati ma micelles amapangidwa mu yankho, amatha kugawidwa kukhala sopo ndi ma polima osungunuka m'madzi.
Polysoap
Sopo ambiri amanyamulidwa, ofanana ndi ma polyelectrolytes. M'malo mwake, sopo ambiri ndi zopangidwa ndi hydrophobic modification ya polyelectrolytes ndipo nthawi zambiri sasungunuka m'madzi. Pakali pano pali mitundu ingapo ya sopo opangidwa (pomwe R imayimira alkyl yautali wautali):
Madzi sungunuka polima surfactant
Zopangira ma polima zomwe sizipanga micelles mumsanganizo nthawi zambiri zimakhala zosungunuka m'madzi za polima. Malinga ndi magwero awo, akhoza kugawidwa m'magulu atatu: zachilengedwe, semi synthetic, ndi synthetic polymer surfactants.
ma polima Natural monga zosiyanasiyana wamba mtengo chingamu, wowuma, tizilombo fermented polysaccharides, etc;
Ma polima opangidwa ndi semi ndi ma polima osiyanasiyana omwe amapezedwa ndi kusintha kwa mankhwala a wowuma, mapadi, ndi mapuloteni, monga cationic wowuma, methyl cellulose, ndi zina;
Ma polima opangira amapangidwa ndi polymerizing monomers yochokera ku petrochemicals, monga zotumphukira za polyacrylamide, polyacrylic acid, etc.
Gulu la Polymer Surfactants
Malinga ndi ionicity yawo m'madzi, amatha kugawidwa mu mitundu ya anionic, cationic, zwitterionic, ndi non-ionic.
Anionic polima surfactant
(1) Ma polima amtundu wa carboxylic acid amaphatikizapo polyacrylic acid ndi copolymers zake, butenoic acid ndi ma copolymers ake, acrylic acid maleic anhydride copolymers, ndi zinthu zawo zomwe zili ndi saponified pang'ono.
(2) Ma polima amtundu wa sulfate ester ndi awa:
(3) Sulfonic acid mtundu
Ena sulfonated polystyrene, benzenesulfonate acid formaldehyde condensate, naphthalene sulfonic acid formaldehyde condensate, sulfonated polybutadiene, etc. Lignosulfonate ndi sulfonic asidi mtundu polima surfactant. Ma sulfonic acid opangidwa ndi polymer surfactants ndi awa:
cationic polima surfactant
Amine salt kapena polyamines monga polyethyleneimine, polyvinylpyrrolidone, polymaleimide, ndi zotumphukira zawo. Ma polima odziwika ndi awa:
(2) Quaternary ammonium salt
Monga quaternized polyacrylamide, polyvinyl pyridine mchere, polydimethylamine epichlorohydrin, etc. Quaternary ammonium polima surfactants amasonyeza cationic katundu acidic, ndale, ndi zamchere amadzimadzi TV. Zoyimira zikuphatikiza:
Amphoteric polima surfactant
Mitundu yayikulu imaphatikizapo acrylic vinyl pyridine copolymer, acrylic acid, cationic acrylic ester copolymer, amphoteric polyacrylamide, etc., monga:
Non ionic polima surfactants
Mitundu yayikulu imaphatikizapo mowa wa polyvinyl ndi zinthu zake zokhala ndi esterified kapena acetalized, monga polyacrylamide yosinthidwa, maleic anhydride copolymer, polyacrylate, polyether, polyethylene oxide propylene oxide, utomoni wosungunuka wa phenolic, utomoni wa amino, etc.
Kapangidwe ndi Katundu Wa Polymer Surfactants
Pamwamba ntchito ya polima surfactants zimadalira morphology wa macromolecules mu njira, amene ali pafupi ndi amphiphilic mankhwala dongosolo, zikuchokera chiŵerengero, ndi wachibale molekyulu kulemera kwa macromolecules.
Mtundu wa block surfactant
Mipikisano chipika zigawo hydrophobic amagawira pa unyolo waukulu wa macromolecules, ndipo kutalika koyenera kwa hydrophobic hydrophilic sequence adzateteza kudzikonda aggregation wa zigawo hydrophobic (kupanga single-molecule micelles) kapena intermolecular aggregation (Mipikisano molekyulu aggregation)
Chisa chooneka ngati surfactant
Ma surfactants ooneka ngati chisa ali ndi ubwino wokonzekera mosavuta komanso mitundu yosiyanasiyana. Ma Surfactants amatha kupezeka ndi homopolymerization kapena copolymerization ya amuna ndi akazi komanso amphiphilic monomers. Kutengera momwe magulu a hydrophobic ndi hydrophilic alili, amawonetsa mitundu yosiyanasiyana yama mankhwala.
Chifukwa cha kukhalapo kwa magulu a hydrophilic pamaketani am'mbali, kuphatikizika ndi kuyanjana kwa zigawo za hydrophobic zimalephereka. Ngakhale mu micelles yomwe idapangidwa kale, poyerekeza ndi micelles yodzaza kwambiri, mkati mwake ndi lotayirira ndipo imakhala ndi mamolekyu ambiri amadzi, motero amawonetsa ntchito yapamwamba; Pakalipano, chifukwa cha kasinthidwe, nthambi za amphiphilic zimatha kulepheretsa kumanga maunyolo akuluakulu a hydrophobic omwe amapangidwa ndi magulu a methylene ndi methylene, kuwalola kutenga nawo mbali pamayendedwe apakati.
Kafukufuku wasonyeza kuti chinthu chilichonse chomwe chimawonjezera kulimba kwa unyolo wa maselo pomwe kusunga kusungunuka kumakhala kopindulitsa pakutambasula kwa ma macromolecules mu yankho ndipo kumatha kupititsa patsogolo ntchito ya ma polima.
Kugwiritsa ntchito ma Polymer Surfactants
Kugwiritsa ntchito makampani osindikizira nsalu ndi utoto
Polyether zochokera polima surfactants zambiri ntchito monga otsika thobvu zotsukira, emulsifiers, dispersants, defoamers, antistatic wothandizila, wetting wothandizira, kusindikiza ndi utoto wothandizira, etc; Polyvinyl mowa ndi zina macromolecular mankhwala chimagwiritsidwa ntchito ngati thickeners ndi zoteteza colloids pokonzekera odzola kusindikiza ndi utoto wothandiza; Zochokera ku cellulose monga carboxymethyl cellulose zimagwiritsidwa ntchito mu zotsukira ngati anti fouling agents; Lignosulfonate ndi phenolic condensate sulfonate amagwiritsidwa ntchito ngati dispersants kwa utoto wosasungunuka.
