Zogulitsa zathu zazikulu: Amino silikoni, silikoni chipika, silikoni hydrophilic, onse a silikoni emulsion awo, nyongolotsi akusisita fastness improver, madzi othamangitsa (Fluorine free, Mpweya 6, Mpweya 8), demin kutsuka mankhwala (ABS, Enzyme, Spandex mtetezi, Manganese remover) , Maiko otumiza kunja: India, Pakistanrk, Bangladesh, Türkçe

 

Kuchapira kwa ma surfactants ndizomwe zimapangitsa kuti ma surfactants agwiritse ntchito kwambiri. Zimakhudza moyo watsiku ndi tsiku wa zikwi za mabanja. Ndipo yakhala ikugwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana komanso kupanga mafakitale.

Kuyeretsa kowuma ndi njira yotsuka mu zosungunulira za organic, zomwe zimagwiritsa ntchito kusungunuka kwa zosungunulira ndi kusungunuka kwa ma surfactants kuchotsa dothi pamwamba pa nsalu. Ubwino wake ndikuti umatha kuletsa kuchepa kosasinthika kwa nsalu zaubweya ndi silika chifukwa cha kutsuka, komanso kupunduka komanso kumva bwino m'manja kwa zovala.

 

Dothi pansalu likhoza kugawidwa m'magulu atatu: mafuta osungunuka, osungunuka m'madzi, komanso osasungunuka mafuta ndi madzi.

Mafuta sungunuka dothi akhoza kuchotsedwa mwachindunji ndi organic solvents. Mafuta osungunulira omwe angagwiritsidwe ntchito kuchapa ndi ma hydrocarbons opepuka a petroleum, makamaka opangidwa ndi ma aliphatic hydrocarbons monga 1,3-diethylcyclohexane, cycloaliphatic hydrocarbons, ndi 1,2,4-trimethylphenylaromatic hydrocarbons. Komanso, palinso carbon tetrachloride, trichlorethylene, tetrachlorethylene, etc.

Kuti muchotse litsiro ndi kusungunuka kwamadzi kwabwino kapena hydrophilicity yamphamvu, madzi pang'ono ndi ma surfactants ayenera kuwonjezeredwa ku dongosolo. Kuwonjezera kwa surfactants kungalepheretse kuyikanso kwa dothi lolimba mu zosungunulira. The kupezeka bata ndi kuyimitsidwa dothi mu organic TV salinso zimadalira electrostatic repulsion pakati particles, koma angadziŵike ndi adsorption wa surfactants pa olimba-zamadzimadzi mawonekedwe.

Ma Surfactants mu organic media adsorb pa malo olimba ngati magulu a polar, okhala ndi maunyolo a lipophilic hydrocarbon olunjika ku malo adsorption a zosungunulira za organic komanso zokongoletsedwa pamawonekedwe olimba amadzimadzi. Izi zikhoza kupanga solvation filimu ya unyolo mpweya wa haidrojeni pamwamba pa dothi olimba, kupanga chotchinga mphamvu kwa malo kuletsa ndi kupewa kudzikundikira kapena kukonzanso mafunsidwe dothi pamwamba nsalu. Kukhalapo kwa madzi ochepa kungayambitse hydration ya tinthu tating'onoting'ono ndi nsalu, zomwe zimapangitsa kuti zikhale zosavuta kuti azilumikizana ndi magulu a polar of surfactants, omwe ndi opindulitsa pakupanga ma surfactants pamalo olimba (makamaka polar polar). Izi ndizopindulitsa pakuchapira bwino. Kuphatikiza apo, ma surfactants akapanga ma reverse micell mu zosungunulira za organic, madzi pang'ono ndi dothi lake losungunuka m'madzi nthawi zambiri amasungunuka mu ma micelles am'mbuyo nthawi imodzi.

 

Ma surfactants omwe amagwiritsidwa ntchito poyeretsa zowuma ayenera kukwaniritsa izi:

① Iyenera kusungunuka pakutsuka zosungunulira ndikupanga ma micelles osinthika, ndikukhala ndi kuthekera kokwanira kowonjezera madzi osungunuka Imatha kumwaza bwino dothi lolimba ndikupereka kukhazikika kwayimitsidwa muzosungunulira organic;
③ Zotsalira zotsalira zotsalira pazochapira ndi zosefera;
④ Palibe fungo, palibe zoyipa pakuchapira, palibe kuwononga zitsulo, ndi zina.

Ma surfactants omwe amagwiritsidwa ntchito poyeretsa amayenera kusungunuka mosavuta mu organic media.

 

Zomwe zimagwiritsidwa ntchito kwambiri ndi izi:

① Ma anionic surfactants monga petroleum sulfonate, sodium alkylbenzenesulfonate (kapena mchere wa amine), ndi sodium succinate sulfonate;

② Zopanda ma ionic monga polyoxyethylene alkyl alcohol ethers, polyoxyethylene alkyl phenols, polyoxyethylene alkyl amides, etc.
