Surfactants: mukuru ruzivo

Surfactants - remubatanidzwa kuti sei pamusoro makakatanwa. Panguva kukurukurirana emura mamorekuru therebetween vari kuumbwa traction. simba Izvi zvichava zvakasiyana zviri pamusoro uye mukati (zvakadzama) akaturikidzana. Tichitarisa mamiriro nemvura, zviri nyore kumisa kuti zvacho, izvo tinotungamirirwa mugadziriro, kubva kumativi akasiyana takapoteredzwa chete mamorekuru chokuita navo. Pamusana mauto zvose kuti chiito morekuru kuri razero. Naizvozvo, nemvura ine yakadereresa pamusoro kuti vhoriyamu kupiwa. Izvi zvinonyatsoratidzwa wakaratidzwa muchimiro idenderedzwa madonhwe. Kuvapo netsvina siyana yeimwe vari zvinwiwa kunokonzera pemvura makakatanwa.

Sechivako surfactant mamorekuru

mafuta acids uye alcohols nezvimedu ine zvikamu zviviri zvine ehupfumi zvakasiyana, zvisinei, yeimwe izvi kazhinji vachinzi diphilic hurongwa. Chimwe chikamu Morekuru inomiririrwa yeHydrocarbon cheni, uye mumwe - akasiyana dzichipfekeka mapoka (amino, hydroxyl, carboxyl, sulfo). Kureba yeHydrocarbon cheni, chikuru chichaitwa kuratidzwa hydrophobic ehupfumi yacho inoramba, vachaita sei nemvura simba.

Pamusoro-basa yeimwe (surfactants) makemikari mavambo: bile acids, mapuroteni, Sipo, alcohols, ketones, aldehydes, tannins, ketones, etc. Pamusoro-basa zvinhu regai kukanganisa pamusoro makakatanwa (starch, shuga, fructose).

Nonionic surfactants (nonionic surfactant) - biosoedineniya yakakwirira samolecular uremu, mvura iyo ions hatuzoumbiki. The reservoirs izvi zvinhu vanoita pamwe indasitiri (namakemikari, Whitehead Textile, oiri), zvipfuwo, mhuri (kushandisa dzakasiyana-siyana chakaita zvokugadzirwa detergents kumba) rinosakara, uyewo tsvina matongo kubva zvokurima (sora, fungicides, zvipembenene, uye zvakare Tomes mu sezvo emulsifiers).

Surfactants kuwana hunoshandiswa vakawanda upfumi. In rokurima nemauto, vari kushandiswa achigadzirira emulsions, wettable Nezvakakuyiwa, uyewo tsika chirimwa kudzivirirwa zvipukanana. Research inoitwa nokushandisa surfactants kuderedza kwemvura kubva muvhu pamusoro. Kana mvura ivhu wemisanganiswa vane sezvamunoita yakadaro, ultrathin firimu aumba pasi pechiso aro kunodzivisa ari kwemvura ine mwando, asi panguva imwe chete nayo zvakakwana nemhepo uye kunayisa. Kana muitiro michero nemiriwo surfactant mhinduro, havana refu kuramba juiciness uye freshness. Kana kuwedzera surfactant kuti inosimbisa kuwedzera uremu mhuka uye shiri vanenge 20% tichienzanisa kudzora mhuka.

Surfactants: Chinokanganisa uye zvakanakira

The pose Makakatanwa kwakakosha nokuti dzinotsanagura Absorção de Água muviri ari dumbu. Somuenzaniso, kwemafuta uye lipids ari zvomudumbu turakiti anouya dziri mumate. Recent emulsified ari ura duku nokuda bile acids. Chete ipapo mafuta aya hydrolyzed ne lipolytic makemikari. Kakawanda, kuvandudza kunyatsoshanda kuti zvipembenene wakawedzera sipo (surfactants). Manipulations zvipembenene anobvumira nani dyidzana pamwe zvipembenene muviri pamusoro. Zvisinei, surfactants havana chete zvakanaka asiwo Migumisiro pamusoro muviri. Somuenzaniso, muna shambuu nziyo zvinokuvadza chaizvo anopupuma nevasori (surfactants), zvakadai yavaibvisa uye Ammonium lauryl sulfate, Ammonium uye yavaibvisa laureth sulfate. Zvinofungidzirwa kuti zvinoriumba ava carcinogenic zvazvinoita.
