Imiti igabanya ubushyuhe bw'amazi, umuti n'umuti uvamo, ikarinda ifuro kwirema, cyangwa ikagabanya ifuro rivamo mu nganda. Imiti ikoreshwa mu kurwanya ubushyuhe ni iyi ikurikira:

I. Amavuta karemano (ni ukuvuga amavuta ya soya, amavuta y'ibigori, n'ibindi)

Ibyiza: irahari, ihendutse kandi yoroshye kuyikoresha;

Ingaruka mbi: biroroshye kwangirika no kongera agaciro ka aside iyo bitabitswe neza.

II.Alcool nyinshi ya karuboni

Alcool nyinshi ya karuboni ni molecule ifite ubushobozi bwo kudafata amazi neza kandi idafite ubushobozi bwo kudafata amazi neza, ikaba ari igikoresho cyiza cyo kurwanya ifuro mu buryo bw'amazi. Ingaruka zo kurwanya ifuro zijyanye no gushonga kwayo no gukwirakwira kwayo mu gifuro. Alcool ya C7 ~ C9 ni yo Antifoamers nziza cyane. Alcool nyinshi ya karuboni ya C12 ~ C22 itegurwa hamwe n'ibikoresho bifasha mu gukurura ifuro bifite ingano ya 4 ~ 9μm, hamwe na emulsion y'amazi ya 20 ~ 50%, ni ukuvuga defoamer mu buryo bw'amazi. Hari esters zimwe na zimwe zifite ubushobozi bwo kurwanya ifuro mu gushyushya penicilline, nka phenylethanol oleate na lauryl phenylacetate.

III.Ibikoresho byo kurwanya ifuro bya polyether

1. Ibikoresho byo kurwanya ifuro bya GP

Yakozwe hifashishijwe polimerasiyo ya propylene oxide, cyangwa uruvange rwa ethylene oxide na propylene oxide, hamwe na glycerol nk'ikintu gitangira. Ifite ubushobozi buke bwo gushonga no gushonga mu buryo bwo gushonga, bityo ikaba ikwiriye gukoreshwa mu mazi yoroshye yo gushonga. Kubera ko ubushobozi bwayo bwo kurwanya gushonga buruta ubwo gushonga, ikwiriye kongerwa mu buryo bwo hasi kugira ngo ibuze inzira yo gushonga mu buryo bwose bwo gushonga.

2. Ibikoresho byo kurwanya ifuro bya GPE

Okiside ya etileni yongerwa ku mpera y'uruhererekane rwa polypropylene glycol rwa GP Antifoamers kugira ngo hakorwe polyoxyethylene oxypropylene glycerol ifite impera y'amazi. GPE Antifoamer ifite ubushobozi bwo gushonga neza, ubushobozi bukomeye bwo kurwanya ifuro, ariko kandi ifite ubushobozi bwinshi bwo gushonga butuma igihe gito cyo kuyirinda ifuro kidakomeza. Kubwibyo, igira ingaruka nziza mu mushongi w'ifuro urimo gushyuha.

3. Ibikoresho byo kurwanya ifuro bya GPE

Copolymer y'igice gifite iminyururu idafite amazi ku mpera zombi n'iminyururu idafite amazi ikorwa binyuze mu gufunga impera y'umunyururu wa GPE Antifoamers na stearate idafite amazi. Molekile zifite iyi miterere zikunda guteranira ku gice cy'umwuka n'amazi, bityo zigira imikorere ikomeye ku buso kandi zigakora neza cyane mu gusukura.

IV.Silicone yahinduwe na Polyether

Polyether Modified Silicone Antifoamers ni ubwoko bushya bw'ibikoresho bigabanya ubushyuhe mu buryo bworoshye. Birahendutse kandi bifite akamaro ko gukwirakwira neza, ubushobozi bukomeye bwo gukumira ifuro, kuguma mu buryo burambye, kudahumanya kandi nta kibazo, kudahindagurika cyane no kuba bifite ubushobozi bukomeye bwo kurwanya ifuro. Dukurikije uburyo butandukanye bwo guhuza imbere, ishobora kugabanywamo ibice bibiri bikurikira:

1. Copolymer ifite umugozi wa -Si-OC- wakozwe hamwe na aside nk'umusemburo. Iyi defoamer yoroshye kuyikuraho kandi ifite ubushobozi buke bwo kuyihindura. Iyo hari amine buffer, ishobora kugumana igihe kirekire. Ariko kubera igiciro cyayo kiri hasi, ubushobozi bwo kuyiteza imbere buragaragara cyane.

2. Copolymer ifatanye na – si-c-bond ifite imiterere ihamye kandi ishobora kubikwa imyaka irenga ibiri mu gihe ifunze. Ariko, bitewe n'ikoreshwa rya platine ihenze nk'umusemburo mu ikorwa, ikiguzi cyo gukora ubu bwoko bwa antifoamers kiri hejuru, bityo nticyakoreshejwe cyane.

V. Indabyo ya Silicon y'umwimerere irwanya ifuro
