V. Organic Silicon Antifoamer
Polydimethylsiloxane, inozivikanwawo sesilicone mafuta, ndiyo chikamu chikuru chesilicone defoamer. Kuenzaniswa nemvura uye nemafuta akajairika, kushushikana kwayo kwepamusoro kudiki, kwakakodzera kune ese mvura-based foaming system uye oiri-based foaming system. Oiri yeSilicone ine yakakwira chiitiko, yakaderera solubility, yakagadzika makemikari zvivakwa, chiedza chekushandisa renji, yakaderera kudzikama, isiri-chepfu, uye yakakurumbira defoaming kugona. Izvo zvisingabatsiri ndezvakashata foam inhibition performance.
1. Solid Antifoamer
Solid Antifoamer ine hunhu hwekugadzikana kwakanaka, maitiro ari nyore, kufambisa kuri nyore uye kushandisa nyore. Inokodzera ese eiri chikamu chemafuta uye chikamu chemvura, uye yepakati dispersion mhando zvakare yakakurumbira. Inoshandiswa zvakanyanya mumunda wefoam yakaderera kana isina furo yekugeza poda.
2. Emulsion Antifoamer
Iyo silicone oiri mu emulsion defoamer ine tension yakakura, uye emulsification coefficient yakakura kwazvo. Kana iyo emulsifier yasarudzwa zvisina kunaka, ichaita kuti defoaming agent igadzirwe uye metamorphic munguva pfupi. Kugadzikana kwe emulsion kunonyanya kukosha kumhando ye defoaming agent. Nokudaro, kugadzirira emulsion type silicone defoamer inotarisa pakusarudza emulsifier. Panguva imwecheteyo, iyo emulsion defoamer ine yakakura dosage musilicone defoamer ine hunhu hwemutengo wakaderera, yakakura application scope, pachena defoaming mhedzisiro, zvichingodaro. Nekufambira mberi kwehunyanzvi hwekugadzira, emulsion defoamer inokura zvakanyanya.
3. Solution Antifoamer
Ndiyo mhinduro yakagadzirwa nekunyungudutsa silicone mafuta mu solvent. Yayo defoaming musimboti ndeyekuti silicone oiri zvikamu zvinotakurwa ne solvent uye zvakaparadzirwa mufuro mhinduro. Mukuita uku, mafuta esilicone anozonyura zvishoma nezvishoma kuita madonhwe kuti apedze kuburitsa furo. Silicone mafuta yakanyungudutswa mune isiri-aqueous organic solution system, senge polychloroethane, toluene, nezvimwewo, inogona kushandiswa semafuta ekugadzirisa defoaming.
4. Mafuta Antifoamer
Chinhu chikuru chemafuta defoamer dimethyl silicone oiri. Yakachena dimethyl silicone mafuta haina defoaming mhedzisiro uye inoda emulsified. Iko kushushikana kwepamusoro kwe emulsified silicone kunodzikira nekukurumidza, uye shoma inogona kuwana yakasimba kuputswa kwefuro uye inhibition. Kana mafuta esilicone akasanganiswa neimwe chikamu chehydrophobically kurapwa silica vabatsiri, mafuta emusanganiswa defoamer anogona kuumbwa. Silicon dioxide inoshandiswa sekuzadza, nokuti yakawanda yemapoka e-hydroxyl pamusoro payo inogona kuwedzera simba rekuparadzira resilicone mafuta mumhepo inoputika, kuwedzera kugadzikana kwemulsion, uye zviri pachena kuti inovandudza pfuma yesilicone defoamer.
Nekuti mafuta esilicone ane lipophilic, silicone defoamer ine yakanakisa defoaming mhedzisiro paoiri-soluble solution. Nekudaro, aya mapoinzi anofanirwa kutariswa kana uchishandisa silicone defoamer:
● Low viscosity silicone defoamer ine yakanaka defoaming effect, asi kuramba kwayo kwakaipa; Yakakwira viscosity silicone defoamer ine inononoka defoaming mhedzisiro asi yakanaka kushingirira.
● Kana iyo viscosity yemushonga unoputika yakaderera, zviri nani kusarudza silicone defoamer ine viscosity yakakwirira. Pane zvinopesana, iyo yakakwira viscosity yemushonga unopupuma, zviri nani kusarudza iyo silicone defoamer ine yakaderera viscosity.
● Huremu hwema molecular yeoil silicone defoamer ine imwe pesvedzero pakusvibisa kwayo.
● Iyo defoamer ine yakaderera molecular uremu iri nyore kuparadzira uye kunyungudika, asi kushaikwa kwekutsungirira. Pane zvinopesana, iyo yekubvisa furo kweyakakwira molecular weight defoamer haina kunaka, uye emulsification yakaoma, asi solubility haina kunaka uye kusimba kwayo kwakanaka.
