Sodium Laureth Sulfate CAS 3088-31-1
Sodium Laureth Sulfate CAS 3088-31-1 Ruzivo
Zvenyama
Kuonekwa: Iyo yakajairwa sodium laureth sulfate imvura isina ruvara kana yakareruka yero viscous, iyi viscous texture inobva mukupindirana kweintermolecular, senge hydrogen bonding, iyo inoonawo kuti inoda kuchinjirwa kune chaiyo michina mukurongedza uye yekufambisa kudzivirira masara uye kuvhara. .
Solubility: Iyo ine yakanakisa kunyungudika kwemvura, nekuda kwechikamu che polyether cheni uye sulfonic acid boka mune molecular chimiro, iyo inogona kukurumidza ionized mumvura kuti iite yakagadzikana anion, iyo inoita kuti molecule yese ipararire nyore mumvura kuita yakajeka uye yakajeka. transparent solution, iyo yakanakira kushandiswa mune dzakasiyana siyana dzemvura-based formula masisitimu.
Melting point uye density: Sezvo iri mvura, hazvina zvazvinoreva kutaura pamusoro pekunyungudika; Density yaro inowanzokwira zvishoma pane iyo yemvura, pakati pe 1.05 ne 1.08 g/cm³, uye density data inobatsira kuverengera nemazvo vhoriyamu uye kutendeuka kukuru panguva yekugadzira uye dosing.
Chemical properties
Surfactant: Seyakasimba surfactant, inoderedza zvakanyanya kushushikana kwemvura. Kana yawedzerwa kumvura, mamorekuru anongoerekana aenda kumhepo-yemvura interface, nekuguma kwehydrophobic kunosvika kumhepo uye kuguma kwehydrophilic kusara mumvura, zvichikanganisa kurongeka kwekutanga kwemamorekuru emvura, zvichiita kuti zvive nyore kuti mvura ipararire. uye kunyorova panzvimbo dzakasimba, nekudaro zvichiwedzera kugona kuchenesa, emulsify, furo, nezvimwe.
Kugadzikana: Inogona kuchengetedza kugadzikana kwakanaka kwemakemikari muhupamhi hwepH (kazhinji pH 4 - 10), iyo inoita kuti ive yakakodzera kune zvakasiyana-siyana zvekugadzirwa kwechigadzirwa munzvimbo dzakasiyana-siyana dzeasidhi-alkali, asi pasi pekuita kwenguva refu kweasidhi yakasimba uye alkalis. , hydrolysis uye kuora kunogonawo kuitika, kukanganisa kushanda.
Kudyidzana nezvimwe zvinhu: kana ikasangana ne cationic surfactants, ichaita mvura inonaya nekuda kwekukwezva kwechaji uye kurasikirwa nebasa rayo repamusoro; Nekudaro, kana yasanganiswa nemamwe anionic uye nonionic surfactants, inogona kazhinji kuwiriranisa kuti iwedzere kukwenenzvera kuchenesa uye kupupa kuita kwekugadzira.
Kugadzirira nzira:
Kazhinji, lauryl doro rinoshandiswa sechinhu chekutanga, uye ethoxylation reaction inoitwa kutanga, uye nhamba dzakasiyana dzeethylene oxide units dzinounzwa kuti uwane laureth. Zvadaro, mushure mekuita sulfonation uye neutralization nhanho, iyo laureth polyester inorapwa ne sulfonating agents senge sulfur trioxide, uye yozogadziriswa nekuwedzera sodium hydroxide kuti pakupedzisira igadzirire sodium laureth sulfate. Iyo yese maitiro inodzorwa zvakanyanya nekuita tembiricha, kudzvanywa uye reshiyo yezvinhu, uye mhando yechigadzirwa ichakanganiswa kana paine musiyano mudiki mudziva.
use
Zvigadzirwa zvekuchengeta pachezvako: Icho chinhu chakakosha mukuchenesa zvigadzirwa zvakaita seshamposi, gels dzekugeza, uye sanitizer yemaoko, izvo zvine basa rekugadzira rakapfuma uye rakakora lather kuti rive rinonakidza ruzivo ruzivo, uku uchibvisa zvine simba mafuta netsvina kubva paganda nebvudzi. , zvichisiya vashandisi kunzwa kuzorodzwa uye kuchena.
Mudzimba dzekuchenesa dzimba: Mumidziyo yekuchenesa mumba senge sipo yendiro uye yekugezesa mbatya, simba rekuchenesa repamusoro reSLES uye kunyungudika kwemvura kwakanaka kunobatsira kubvisa nemazvo tsvina dzakasindimara pandiro nembatya, uye hunhu hwayo hunopupuma hunogonawo kubatsira vashandisi kuona chiyero chehutsanana.
Kucheneswa kwemaindasitiri: Mune zvimwe zviitiko zvemaindasitiri, sekuchenesa simbi uye kuchenesa mota, zvinobatsirawo kubvisa tsvina yakaita seoiri neguruva uye kunatsiridza kuchenesa uye kunaka nekugona kwayo kusvibisa uye emulsification.
