Kodi zofewetsa nsalu ndi ziti?

A wofewetsandi mtundu wa mankhwala omwe amatha kusintha ma static ndi dynamic friction coefficients a ulusi. Pamene static friction coefficient isinthidwa, tactile kumva kumakhala kosalala, kumapangitsa kuyenda kosavuta kudutsa ulusi kapena nsalu. Pamene kugunda kwamphamvu kumasinthidwa, microstructure pakati pa ulusi imathandizira kusuntha, kutanthauza kuti ulusi kapena nsalu zimakhala zosavuta kusintha. Kumverera kophatikizana kwa zotsatirazi ndizomwe timawona ngati zofewa.

Zofewa zimatha kugawidwa ndi ma ionic m'mitundu inayi: cationic, nonionic, anionic, ndi amphoteric.

Ofewetsa Omwe Amagwiritsidwa Ntchito Nthawi zambiri Amaphatikizapo:

1. Zofewa Zopangidwa ndi Silicone

Zofewa izi zimapereka kusalala bwino komanso kutsetsereka, koma choyipa chawo chachikulu ndi kukwera mtengo, zomwe zimawonjezera ndalama zopangira. Kuphatikiza apo, zimakonda kuyambitsa kusamuka kwamafuta ndi mawonekedwe a silicone pakagwiritsidwa ntchito, zomwe zimapangitsa kuti zikhale zosayenera pakukula kwanthawi yayitali m'makampani amakono omwe akupikisana nawo.

2. Mafuta a Acid Salt Softeners (Ofewetsa Flakes).

Izi makamaka zimakhala ndi mafuta amchere amchere ndipo ndizosavuta kugwiritsa ntchito. Komabe, amafunikira ndalama zambiri, zomwe zimapangitsa kuti pakhale ndalama zambiri, zomwe sizikugwirizana ndi kufunikira kochepetsa ndalama zonse ndikukweza phindu la mafakitale.

3. D1821

Kuipa kwakukulu kwa chofewa chamtunduwu ndi kusawonongeka kwake kwachilengedwe komanso kukhala kwachikasu kosalekeza. Ndi kukula kwachidziwitso kwa anthu komanso kukhwima kwa chikhalidwe cha dziko ndi mayiko, zinthu zoterezi sizingakwaniritse zofuna za chitukuko chokhazikika.

4. Esterquaternary Ammonium Salts (Mtengo wa TEQ-90)

Zofewa izi zimapereka magwiridwe antchito okhazikika, amafunikira kugwiritsidwa ntchito pang'ono, ndipo amawonekera chifukwa cha kuwonongeka kwawo kwachilengedwe. Amaperekanso maubwino angapo, kuphatikiza kufewa, antistatic properties, fluffiness, anti-yellowing, ndi antibacterial disinfection. Zinganenedwe kuti mtundu uwu wa wothandizira wofewetsa umayimira zochitika zazikulu m'tsogolomu zamakampani ochepetsetsa.
