Kodi zofewetsa nsalu zimagawidwa m'magulu ati?

A chofewetsandi mtundu wa mankhwala omwe angasinthe ma coefficients osasunthika komanso osinthasintha a ulusi. Pamene coefficient yosasunthika yasintha, kukhudza kumakhala kosalala, zomwe zimapangitsa kuti kuyenda kosavuta kudutsa ulusi kapena nsalu kukhale kosavuta. Pamene coefficient yosinthasintha yasinthasintha, kapangidwe ka microstructure pakati pa ulusi kumathandiza kuyenda kwa onse, zomwe zikutanthauza kuti ulusi kapena nsalu zimakhala zosavuta kusintha. Kugwirizana kwa zotsatira izi ndi komwe timakuona ngati kufewa.

Zofewetsa zimatha kugawidwa m'magulu anayi malinga ndi makhalidwe awo a ionic: cationic, nonionic, anionic, ndi amphoteric.

Mankhwala Ofewetsa Omwe Amagwiritsidwa Ntchito Kawirikawiri Amaphatikizapo:

1. Zofewetsa Zochokera ku Silicone​

Zofewa izi zimapereka kusalala bwino komanso kutsetsereka bwino, koma vuto lawo lalikulu ndi mtengo wawo wokwera, zomwe zimapangitsa kuti ndalama zogwirira ntchito ziwonjezeke. Kuphatikiza apo, nthawi zambiri zimayambitsa kusamuka kwa mafuta ndi madontho a silicone akagwiritsidwa ntchito, zomwe zimapangitsa kuti zisagwiritsidwe ntchito kwa nthawi yayitali m'mafakitale amakono omwe akupikisana kwambiri.

2. Zofewetsa Mchere wa Mafuta (Zofewetsa Zidutswa)​

Izi makamaka zimakhala ndi mchere wamafuta acid ndipo ndizosavuta kugwiritsa ntchito. Komabe, zimafuna kuchuluka kwakukulu, zomwe zimapangitsa kuti pakhale ndalama zambiri, zomwe sizikugwirizana ndi kufunikira kochepetsa ndalama zonse ndikukweza phindu la mafakitale.

3. D1821​

Zoyipa zazikulu za mtundu uwu wa chofewetsa ndi kusawonongeka kwake komanso chikasu. Chifukwa cha chidziwitso cha anthu ambiri komanso miyezo yokhwima yazachilengedwe m'dziko ndi padziko lonse lapansi, zinthu zotere sizingakwaniritsenso zofunikira pakukula kokhazikika.

4. Mchere wa Ammonium wa Esterquaternary (TEQ-90)

Zofewetsa izi zimapereka mphamvu yokhazikika yofewetsa, sizifuna kugwiritsidwa ntchito kwambiri, ndipo zimaonekera bwino chifukwa cha kusungunuka bwino kwa zinthu. Zimaperekanso zabwino zambiri, kuphatikizapo kufewa, mphamvu zoletsa kutentha, kufewa, kukana chikasu, komanso kupha tizilombo toyambitsa matenda. Tinganene kuti mtundu uwu wa mankhwala ofewetsa umayimira njira yodziwika bwino mtsogolo mwa makampani ofewetsa.
