Kugwiritsa ntchito ma surfactants otulutsa thovu mu mankhwala ophera tizilombo toyambitsa matenda

Pambuyo powonjezera mankhwala ophera thovu ku mankhwala ophera tizilombo toyambitsa matenda ndikugwiritsa ntchito mfuti yapadera yophera thovu pophera tizilombo toyambitsa matenda, pamwamba pake pamakhala "woyera" wooneka bwino pambuyo pophera tizilombo toyambitsa matenda, zomwe zimasonyeza bwino madera omwe mankhwala ophera tizilombo toyambitsa matenda aphera tizilombo toyambitsa matenda. Njira yophera tizilombo toyambitsa matenda pogwiritsa ntchito thovu yakhala ikuvomerezedwa kwambiri ndi kuvomerezedwa ndi minda yambiri.

Gawo lalikulu la mankhwala opangira thovu ndi surfactant, chinthu chofunikira kwambiri mu mankhwala abwino, omwe nthawi zambiri amatchedwa "industrial MSG." Mankhwala opangira thovu ndi zinthu zomwe zimatha kuchepetsa kwambiri kupsinjika kwa pamwamba pa yankho lolunjika. Ali ndi magulu osasunthika a hydrophilic ndi lipophilic ndipo amatha kukhazikika molunjika pamwamba pa yankho. Mwa kusakaniza pamalo olumikizirana pakati pa magawo a mpweya ndi madzi, amachepetsa kupsinjika kwa pamwamba pa madzi. Angathenso kuchepetsa kupsinjika kwa pakati pa mafuta ndi madzi mwa kusakaniza pamalo olumikizirana amadzimadzi ndi madzi. Ndi ntchito zosiyanasiyana komanso ntchito zosiyanasiyana, mankhwala opangira thovu amapereka mphamvu monga kusungunuka, kukhuthala, emulsification, wetting, thovu/defoaming, kuyeretsa ndi kuchotsa kuipitsidwa, kufalikira, kuyeretsa ndi kupha tizilombo toyambitsa matenda, zotsatira zotsutsana ndi static, kufewetsa, ndi kusalala.

Kutulutsa thovu ndi ntchito yofunika kwambiri ya ma surfactants. Ma surfactants a thovu amatha kuchepetsa mphamvu ya madzi pamwamba ndikuyika mu gawo lamagetsi lawiri pamwamba pa filimu yamadzi kuti agwire mpweya, ndikupanga thovu. Thovu limodzilimodzi limaphatikizana kuti lipange thovu. Ma thovu apamwamba kwambiri amakhala ndi mphamvu yamphamvu yotulutsa thovu, kapangidwe ka thovu kakang'ono, komanso kukhazikika kwa thovu bwino.

Zinthu zitatu zofunika kwambiri kuti tizilombo toyambitsa matenda tizigwira ntchito bwino ndi izi: tizilombo toyambitsa matenda togwira ntchito bwino, kuchuluka kwa tizilombo toyambitsa matenda, komanso nthawi yokwanira yokhudzana ndi tizilombo toyambitsa matenda. Ngakhale kuonetsetsa kuti tizilombo toyambitsa matenda tabwino, kugwiritsa ntchito mankhwala ophera tizilombo toyambitsa matenda opangidwa ndi thovu ndikugwiritsa ntchito ndi mfuti yapadera yophera thovu kumawonjezera nthawi yolumikizana pakati pa tizilombo toyambitsa matenda ndi malo omwe akufunidwa komanso tizilombo toyambitsa matenda, motero zimapangitsa kuti tizilombo toyambitsa matenda tizigwira ntchito bwino komanso mokwanira.
