Zvigadzirwa zvedu Zvikuru: Block Silicone, Hydrophic Silicone
Nhanganyaya kune Surfacts
Surfactants gadzira maAmphihilic molecular chimiro: Mumwe mugumo ane hydrophic group, inotaurwa pamusoro peiyo hydrophilic musoro, nepo imwe kuguma ine hydrophobic boka, rinozivikanwa sehydrophobic muswe. Iyo hydrophilic musoro inobvumira surfacts kuti vanyungure mumvura mune yavo monomer fomu.
Boka reHydrophilic kazhinji rinowanzove boka rePolar, iro rinogona kunge riri boka remauto
Iyo hydrophobic group inowanzo polar hydrocarbon cheni, yakadai se hydrophobic alkyl chain (r- yeAlkyl) kana inonhuhwirira mapoka (arming mapoka).
Surfactants inogona kukanganisika muIonic surfachants (kusanganisira cationic uye anonic surfachants), isiri-ionic surfectants, surfects surfersants, surfacants, uye vamwe surfacts, nevamwe. Mumhinduro dzeSurfactant, apo kusarudzika kweiyo siracantant inosvika kune imwe kukosha, mamalekyu anosimuka anoumba akasiyana-siyana akarairwa akarairwa anozivikanwa semicelle. Maitiro eMertization, kana midziyo yekuumbwa, chinhu chakakosha chivakwa chakakosha chemhinduro dzekuzvidzora, sezvinoita zviitiko zvakawanda zvakakosha zvinosanganiswa zvakabatana neyekuumbwa kwemaroji.
Iko kusunganidzwa kune iyo surfacts inoumba micelles mune mhinduro inotaurwa kune iyo yakaoma micellocation (cmc). Micelle haina kugadziriswa, zvivakwa zvetsiva; Asi, ivo vanoratidzira kunyanyisa kusarongeka uye kusimba chimiro chinoshanduka. Pasi pemamwe mamiriro, surfacts inogona zvakare kuratidza reverse micelle nyika.
Zvinhu zvinopesvedzera CMC:
- chimiro cheSurfactant
- Nyora uye kuvapo kwekuwedzera
- Tembiricha
Kubatana pakati pemapurasitari nemapuroteni
Mapuroteni ane asiri-polar, polar, uye nemapoka akaomeswa, uye mamoripiphii mamalekyuli emamolekyudhi anogona kudyidzana nemapuroteni nenzira dzakasiyana siyana. Zvichienderana nemamiriro ezvinhu, surfers
Zvekudyidzana pakati pemapuroteni uye surfers Ionic surfacts inowirirana nemapuroteni zvakanyanya kuburikidza neyemagetsi mauto ehupamhi uye hydrophobic kutaurirana kweiyo aliphatic keteni, kusungira kune hyiphobic matunhu emapuroteni, nokudaro achiumba ps complex.
Asiri-ionic surfers anonyanya kubatidzana nemapuroteni kuburikidza neHydrophobic mauto, apo iyo hydrophobic maketeni inobatana neiyo hydrophobic matunhu emapuroteni emapuroteni. Kubatanidzwa kunogona kukanganisa zvese zvimiro uye kushanda kweiyo siractant uye protein. Naizvozvo, iyo mhando uye yekuvhara kwevasina mamiriro, pamwe nemamiriro ekunze, sarudza kuti surfalit inomutsa kana kuti inoparadza mapuroteni, uye kunyangwe ivo vanosimudzira kuunganidzwa kana kupararira.
HLB Kukosha kweSurfacts
Kuti uwane surfant yekuratidzira yayo yakasarudzika zviitiko, inofanirwa kuyera iyo hydrophobic uye hydrophilic zvikamu. Iyo HLB (hydrophile-lipophile-lipophi chiyero) chiyero chehydrophilic-lipophic chiyero che surfers
Iyo HLB kukosha ndeye hama yakakosha (kubva pa0 kusvika makumi mana). Semuenzaniso, paraffin ine HLB kukosha kwe 0 (hapana hydrophilic component ine hlb kukosha kwe20, sodium dodecyl sulfate) ine hlb kukosha kwe40. Iyo Hlb kukosha inogona kushandira serumbozha kana uchisarudza surfers. Yakakwira HLB kukosha inoratidza zviri nani hydrophilicity, nepo yakadzika HLB kukosha kunoratidza urombo hydrophility.
