Rudzi rweAntiFoamers I

MaAntiFoams anoshandiswa kuderedza kusawirirana kwemvura, mhinduro uye kumiswa, kudzivirira foam kuumbwa, kana kuderedza foam yakaumbwa panguva yekugadzirwa kwemaindasitiri. Zviitiko zvezvidhori ndizvo zvinotevera:

I. Nyaya dzechisikigo (kureva SoYBEAN OIL, OROORO OIL, ETC.)
Zvakanakira: Inowanikwa, inodhura-inoshanda uye nyore kushandiswa.
Zvinokuvadza: Zviri nyore kushatisa uye kuwedzera iyo acid kukosha kana isina kuchengetwa zvakanaka.

Ii. Yakakwirira kabhoni doro
High carbon doro iri mutsara wemutsara ane hydrophos uye isina kusimba hydrophilikuti, iyo inoshanda antifoamer muhurongwa hwemvura. Iyo fanifoaming mhedzisiro yedoro ine hukama nekunyora kwayo uye kusiyana mumhinduro yekupupuma. Doro reC7 ~ c9 ndiyo inonyanya kushanda anonyanya kushanda. Yakakwira kabhoni doro reC12 ~ C22 yakagadzirirwa nemamelsifiers yakakodzera neyekukura kwechiita Vamwe esters zvakare vane maitiro ekufungidzira mumhedzisiro ye penicillin kufemerwa, senge phenylethanol oleate uye layyl phenylacetate.

III. Polyether antifoamers
1. GP antifoamers
Yakagadzirwa nekuwedzera polymerization yeProfyleye oxide, kana musanganiswa we ethylene oxide uye profily oxide, ne glycerol seyekutanga mumiririri. Iyo ine murombo hydrophipotilicity uye yakaderera solubility mune inopupuma svikiro, saka yakakodzera kushandiswa mumvura yakatetepa. Sezvo kugona kwayo kwekufungidzira kwakakwirira kune izvo zvekusazvibata, zvakakodzera kuwedzerwa muBasari svikiro kuti ubvise maitiro ekupupuma ezvikamu zvese zvekufemera.

2. Gpe antifoamers
Etleene oxide inowedzerwa pamugumo wePolypropylene Glycol Chain Link yeGP antifoamers kuumba PolydoxyChillene Oxypropyle Glyceroc End. Gpe antifoamer ane hydrophilikuti yakanaka, kugona kwakasimba kugona, asi zvakare ane solubility yakakura iyo inokonzeresa nguva pfupi yekugadzirisa basa rekutora. Naizvozvo, zvine simba zvakanaka muViscous Fermentation muto.

3. GPES ANOTIFOAMES
A block Copolymer ane hydrophobic maketins pamapeji uye hydrophilic chain inoumbwa nekuisa chisimbiso iyo ketani yekupera kweGpe neHydrophobic Stearate. Mamorekuru aya ane chimiro ichi anounganidza pagesi-yemvura interface, saka vane yakasimba nzvimbo yekuita uye kugona kukuru.

Iv. Polyether yakagadziridzwa silicone
Polyether akagadziridza silicone antifoamers idzva rudzi rutsva rwekunyanyisa. Iyo inodhura-inoshanda nezvakanakira kupararira kwakanaka, simba rakasimba rekudzivirira, kugadzikana, risiri-rine muchetura uye husina simba uye husina hushoma uye hwakadzika uye hwakasimba antiofoamers kugona. Zvinoenderana nemhando dzakasiyana dzemukati dzemukati, inogona kukamurwa mune zvikamu zviviri zvinotevera:

1. Coplymer ne -si-oc- Bond-Bondy yakagadzirirwa neAcid seCatalyst. Iyi defoamer iri nyore kuHydrolysis uye ine kusakwana. Kana amber buffer iripo, inogona kuchengetwa kwenguva refu. Asi nekuda kwemutengo wayo wakaderera, kugona kusimudzira kuri pachena kwazvo.

mabara-sous

2. Iyo Copolymer yakasungwa na - si-c-bond ine chimiro chakagadzikana uye chinogona kuchengetwa kweanopfuura makore maviri pasi pemakore maviri pasi pezvakavharwa. Nekudaro, nekuda kwekushandiswa kwePlatinum inodhura seCatlyst mukugadzira maitiro, mutengo wekugadzira rerudzi urwu rweanodaya, saka hazvina kushandiswa zvakanyanya.

V. Organic silicon antifoamer
... zvinotevera chitsauko.
