Antifoam ya Silicone ni iki?

Ubusanzwe imiti irwanya ifuro ya silikoni igizwe na silikoni ivanze na hydrophobique ikwirakwizwa neza mu mazi ya silikoni. Hanyuma imvange ivamo ihinduka emulsion ishingiye ku mazi cyangwa amavuta. Iyi miti irwanya ifuro igira akamaro kanini bitewe n'uko idashobora gukoreshwa mu buryo bwa shimi, imbaraga zayo ndetse no mu rugero ruto, ndetse n'ubushobozi bwo gukwirakwira ku ifuro. Iyo bibaye ngombwa, ishobora guhuzwa n'ibindi bintu bikomeye birwanya ifuro n'ibinyobwa kugira ngo byongere ubushobozi bwabyo bwo gukurura ifuro.

Ibikoresho birwanya ifuro bya silikoni bikunze kuba byiza. Bikora mu kugabanya ubushyuhe bw'ubuso no kwangiza uduheri tw'ifuro, bigatuma bicika. Iki gikorwa gifasha mu gukuraho vuba ifuro risanzweho ndetse kinafasha mu gukumira ifuro.

Ibyiza bya silicone defoamer

• Porogaramu zitandukanye

Bitewe n'imiterere yihariye y'amavuta ya silikoni, ntabwo ihuye n'amazi cyangwa ibintu birimo amatsinda y'ibice by'izuba, cyangwa na hydrocarbon cyangwa ibintu by'umwimerere birimo amatsinda ya hydrocarbon. Kubera ko amavuta ya silikoni adashonga mu bintu byinshi, silikoni igabanya ubushyuhe ifite akamaro kanini. Ishobora gukoreshwa atari mu buryo bwo gukurura amazi gusa, ahubwo no mu buryo bwo gukurura amavuta.

• Ubushyuhe buke bw'ubuso

Ubuso bw'amavuta ya silikoni muri rusange ni 20-21 dynes/cm kandi ni ntoya ugereranije n'ubuso bw'amazi (72 dynes/cm) n'amazi afuro muri rusange, ibyo bikaba byongera ingaruka zo kugenzura ifuro.

• Ubushyuhe buhamye neza

Dufashe urugero rw'amavuta ya silikoni ya dimethyl akoreshwa cyane, ubushobozi bwayo bwo kwihanganira ubushyuhe bw'igihe kirekire bushobora kugera kuri dogere selisiyusi 150, naho ubushobozi bwayo bwo guhangana n'ubushyuhe bw'igihe gito bushobora kugera kuri dogere selisiyusi zirenga 300, bigatuma imiti igabanya ubushyuhe ya silikoni ishobora gukoreshwa mu bushyuhe bwinshi.

• Gukomera neza mu mikorere y'ibinyabutabire

Amavuta ya silikoni afite ubushobozi bwo guhindagurika cyane mu binyabutabire kandi biragoye kuyakoresha mu buryo bwa shimi hamwe n'ibindi bintu. Kubwibyo, igihe cyose aya mavuta akozwe neza, imiti igabanya ubushyuhe ya silikoni yemerewe gukoreshwa mu buryo burimo aside, alkali n'umunyu.

• Uburemere bw'umubiri

Byagaragaye ko amavuta ya silikoni adahumanya abantu n'amatungo. Kubwibyo, amavuta ya silikoni akoreshwa mu gusukura (afite imiti ikoreshwa mu gusukura idahumanya, nibindi) ashobora gukoreshwa mu buryo bwizewe mu mpapuro, mu gutunganya ibiribwa, mu buvuzi, mu buvuzi no mu nganda zikora ibijyanye no kwisiga.

• Gusebya bikomeye

Imashini zikuraho uburozi za silicone ntizishobora gusa gusenya neza ifuro risanzwe ritari rikenewe, ahubwo zinabuza cyane ifuro no gukumira ikorwa ry’ifuro. Igipimo ni gito cyane, kandi kimwe cya miliyoni imwe gusa (1 ppm cyangwa 1 g / m3) cy'uburemere bw'icyuma gisohora uburozi gishobora kongerwamo kugira ngo habeho ingaruka zo gukuraho uburozi. Ingano yabyo isanzwe ni hagati ya 1 na 100 ppm. Ntabwo ari igiciro gito gusa, ahubwo ntikizanduza ibikoresho bikurwaho uburozi.

Antifoam za silikoni zihabwa agaciro kubera ko zihamye, zihuye n'ibintu bitandukanye, kandi zikora neza mu rugero ruto. Ariko, ni ngombwa kugenzura ko zubahiriza amabwiriza kandi zikwiriye ikoreshwa ryazo kugira ngo hirindwe ingaruka mbi ku bwiza bw'ibicuruzwa cyangwa ibidukikije.
