【Kuita】2,4,7,9-Tetramethyl-5-decyne-4,7-diol surfactant chigadzirwa ndeye yakawanda inoshanda yekuwedzera nekunyorova, kubvisa-furo uye kuparadzira zvivakwa. Chigadzirwa chacho ndeye symmetrical isiri-ionic surfactant. Yayo yakasarudzika gemini chimiro chemakemikari inoita kuti chigadzirwa chideredze kushushikana kwepamusoro, kudzora furo, uye kuderedza kunzwisiswa kwemvura. Inogona kushandiswa mumaindasitiri mazhinji: akadai semvura-yakavakirwa maindasitiri ekukoira, mvura-yakavakirwa huni pendi, mvura-yakavakirwa epurasitiki pendi, mvura-yakavakirwa inki, OPV, inomira-inomira inonamira, pigment uye dhayi kugadzira, indasitiri yekugadzira simbi, flux. , mishonga yezvipembenene, nezvimwewo.
Iyo inofamba nekukurumidza, inoderedza kusimba kwepasi uye static pamusoro tension, defoams uye inhibits furo, ine yakaderera mvura senitivity, inogona kunyorovesa zvakasiyana-siyana zvesubstrates, haigadziri micelles, ine yakanaka yekudziya kugadzikana, uye ine yakanaka acid-base kugadzikana. Kunyorova kwemvura-kwakavakirwa masisitimu ane tension yakakwira pane yekunyungudutsa masisitimu uye inoda kuwedzera ma surfactants kuvandudza kunyorova. Nekudaro, zvechinyakare wetting agents zvinokonzeresa furo nekudzikamisa furo. Kana ma defoam akawedzerwa, matambudziko asina kunaka ekunyorova senge pinholes anozoonekwa zvakare.
Inogona kudzivisa matambudziko aya. Kuita kwacho kuri nani zvakanyanya pane echinyakare surfactants, uye inogona kupa yakanyanya kuderera pasi tension uye kudzvinyirira furo pasi pemamiriro ane simba.
Nekuda kwechimiro chayo chakasarudzika chemamorekuru, kubvisa furo chinhu chakateerana surfactants yakanaka symmetrical isiri-ionic defoaming mumiriri.
Iyo surfactant haina cloud point uye inogona kuve nekugara kwenguva refu yekubvisa foaming zvivakwa munzvimbo yakakura yekupisa. Kunzwa kwemvura Mazhinji ma surfactants anokonzera matambudziko ekunzwa kwemvura panzvimbo yakavharwa mushure mekuoma.
Yakanyanya hydrophilic surfactants senge anionic (dioctyl sulfosuccinate sodium munyu) kana polyethoxylated surfactants inonyungudika nyore nyore mumvura, zvichikonzera kuremerwa kwepamusoro mumucheka wakaomeswa, sekunamira, kuchena kwebvudzi, fogging, uye kushomeka kwemvura.
Inokurudzirwa kuwedzera emulsion kana resin uye mamwe ma surfactants kutanga, wobva wawedzera 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants. -30 maminitsi. Vamwe 2,4,7,9-Tetramethyl-5-decyne-4,7-diol series surfactants inogona kupenya panguva yekufambisa kana kuchengetedza pakupisa kwakanyanya; kupisa kunyoro panguva yekupararira kudiki kunogona kuvadzoreredza zvakanaka.
Inokurudzirwa Kuwedzera nhanho USE:
Aqueous coating: 0.1% -3.0%
Aqueous pressure sensitive adhesives: 0.1%—1.0%
Tsime mhinduro: 0.1% -1.0%
Jet inki: 0.1%—1.0%
Iyo data iri pamusoro ndiyo huwandu hweempirical, uye iyo yakakwana dosage inotarwa nenhevedzano yebvunzo
Zvakanakira:
Kupararira nokukurumidza, kuderedza dynamic uye static pamusoro tension, defoaming, uye antifoaming, yakaderera mvura kunzwa, wetting siyana substrates pasina kugadzira micelles.good thermal kugadzikana uye acid-alkali kuramba.
Kunyorova:
Mvura-based systems ine high surface tension pane zvinonyungudutsa zvigadziriso, uye zvinodiwa kuti uwedzere surfactant kuti uvandudze kunyorova.Nzvimbo dzechinyakare dzekunyorova dzinowanzokonzera furo nekugadzikana nyaya. Zvigadzirwa zvakatevedzana zvinogona kukunda matambudziko aya, zvichipa kuita kwepamusoro mukupa kuderera kwepasi uye kusvibisa kunyange pasi pemamiriro ane simba.
Defoaming:
Iwo akatevedzana ma surfactants, ane akasiyana mamorekuru chimiro, anoita seakanakisa symmetric asiri-ionic defoaming agents. Ivo vanoratidza inopfuurira defoaming zvivakwa pamusoro pehupamhi tembiricha renji pasina clouding point.
Kunzwa Kwemvura:
Mazhinji ma surfactants anokonzeresa nyaya dzekunzwa kwemvura pane yakaomeswa coating pamusoro. Yakanyanya hydrophilic surfactants senge anionic (dioctyl sulfosuccinate) kana polyethoxylate surfactants inogadzika nyore mumvura, zvichikonzera kukanganisa kwepamusoro mumachira akaomeswa sekunamira uye kuchena, atomization, uye kushomeka kwemvura.
