Zeziphi ii-surfactants ezinokusetyenziswa ukulawula amagwebu ngexesha lokucoca?

Ii-surfactants ezinogwebu oluphantsi zibandakanya iikhompawundi ezininzi ze-nonionic kunye ne-amphoteric ezinamandla okusebenza okubanzi kunye nokusetyenziswa okunokwenzeka. Kubalulekile ukuqaphela ukuba ezi zixhobo ze-surfactants azizo-zero-foaming agents. Kunoko, ngaphezu kwezinye iipropati, zibonelela ngeendlela zokulawula ubuninzi be-foam eyenziwe kwizicelo ezithile. I-Low-foam surfactants nayo ihluke kwi-defoamers okanye i-antifoamers, ezongezo ezenzelwe ngokukodwa ukunciphisa okanye ukuphelisa i-foam. Ii-surfactants zibonelela ngemisebenzi emininzi ebalulekileyo ekuqulunqeni, kubandakanya ukucoca, ukumanzisa, ukumilisela, ukusasaza, nokunye.

Amphoteric Surfactants​

I-amphoteric surfactants eneprofayili yegwebu ephantsi kakhulu isetyenziswa njengezinto ezinyibilikayo emanzini kwiindlela ezininzi zokucoca. Ezi zithako zinika ukudibanisa, ukuzinza, ukucoca, kunye neempawu zokumanzisa. Iinoveli ze-amphoteric surfactants ezisebenzayo zibonisa iimpawu eziphantsi kakhulu zogwebu ngelixa zibonelela ngokucoca, iiprofayili ezibalaseleyo zokusingqongileyo kunye nokhuseleko, kunye nokuhambelana nezinye i-nonionic, cationic, kunye ne-anionic surfactants.

Nonionic Alkoxylates​

I-alkoxylates ye-foam ephantsi kunye ne-ethylene oxide (EO) kunye nomxholo wepropylene oxide (PO) unokuhambisa ukucoca okuphezulu kunye nokusebenza ngokutshiza ukucoca okuphezulu kunye nezicelo zokucoca ngoomatshini. Imizekelo ibandakanya izixhobo zokuhlamba izitya ezizenzekelayo, izicoci zobisi kunye nokutya, ukusetyenzwa kwepulp kunye nephepha, iikhemikhali zamalaphu, nokunye. Ukongeza, ii-alkoxylates ezisekwe etywaleni zinomgca osezantsi kakhulu kwaye zinokudityaniswa nezinye izinto ezinogwebu oluphantsi (umzekelo, iipolima ezinyibilikayo ezinyibilikayo emanzini) ukwenza izicoci ezikhuselekileyo nezinoqoqosho.

EO/PO Block Copolymers​

I-EO / PO block copolymers ziyaziwa ngokugqwesa kwazo ukumanzisa kunye neempawu zokusabalalisa. Ukwahluka kwe-foam ephantsi kolu didi kunokusebenza njenge-emulsifiers esebenzayo kwiinkqubo ezahlukeneyo zokucoca kwimizi-mveliso nakwiziko.

​Iioksidi ze-amine ezinegwebu eliphantsi

Iioksidi ze-amine ezinemilinganiselo yogwebu ephantsi kakhulu nazo ziqatshelwa ngokucocwa kwazo kwizicoci kunye nezicoci. Xa zidityaniswe ne-amphoteric hydrogels ene-foam ephantsi, ii-amine oxides zinokusebenza njenge-surfactant backbone kwimixube emininzi yezicoci zomgangatho oqinileyo we-foam kunye nezicelo zokucoca isinyithi.

I-Linear Alcohol Ethoxylates​

I-alcohol ethoxylates ethile ibonisa amanqanaba amagwebu aphakathi ukuya kuma aphantsi kwaye ingasetyenziswa kwizinto ezahlukeneyo zokucoca umphezulu onzima. Ezi zixhobo zombane zibonelela ngezinto zokucoca ezigqwesileyo kunye neempawu zokumanzisa ngelixa zigcina indalo efanelekileyo, impilo kunye neeprofayili zokhuseleko. Ngokukodwa, i-low-HLB alcohol ethoxylates iphantsi ukuya kwi-foaming ephakathi kwaye inokudibaniswa ne-high-HLB alcohol methoxylates ukulawula i-foam kunye nokuphucula ukunyibilika kweoli kwiindlela ezininzi zokucocwa kwemizi-mveliso.

I-Fatty Amine Ethoxylates​

Amanye amanqatha e-amine ethoxylates aneempawu eziphantsi zogwebu kwaye anokusetyenziswa kwizicelo zezolimo kunye nokucoca okujiyileyo okanye imixube esekwe kwiwax ukubonelela ngeempawu zokuthambisa, ukumanzisa, kunye nokusasaza.
