Kodi ma surfactants amagwiritsa ntchito bwanji zokutira?

Ma SurfactantsNdi gulu lazinthu zomwe zimakhala ndi mamolekyu apadera omwe amatha kulumikizana ndi mawonekedwe kapena malo, amasintha kwambiri kusamvana kwapamtunda kapena mawonekedwe apakati. M'makampani opangira zokutira, ma surfactants amagwira ntchito yofunika kwambiri pakugwiritsa ntchito zosiyanasiyana, kuphatikiza emulsification, kunyowetsa, kubalalitsidwa, kutulutsa thovu, kusanja, zotsatira za antistatic, ndi zina zambiri, potero kumathandizira kukhazikika, magwiridwe antchito, komanso mtundu womaliza wa zokutira.

1. Emulsification

Mu zokutira zochokera ku emulsion (monga zokutira zamadzi), emulsifiers ndizofunikira. Amachepetsa kusamvana kwapakati pakati pa magawo a mafuta ndi madzi, zomwe zimapangitsa kuti pakhale ma emulsions okhazikika kuchokera ku zigawo zosasinthika. Ma emulsifiers wamba amaphatikizapo anionic surfactants (monga sodium dodecylbenzene sulfonate) ndi nonionic surfactants (monga polyoxyethylene ethers).

2.Kunyowetsa Pigment ndi Kubalalitsidwa

Kubalalika kofanana kwa ma pigment mu zokutira kumakhudza mwachindunji kusawoneka, kukhazikika, ndi magwiridwe antchito amtundu. Zonyowetsa ndi zobalalitsa zimachepetsa kusamvana pakati pa ma pigment ndi zomangira, kulimbikitsa kunyowetsa yunifolomu ndi kubalalitsidwa kokhazikika ndikupewa kusakanikirana ndi kukhazikika.

3.Defoaming ndi Foam Control

Pakupanga ndi kugwiritsa ntchito, zokutira zimakonda kupanga thovu, zomwe zingasokoneze mawonekedwe a kanema ndi magwiridwe antchito. Ma defoamers (mwachitsanzo, opangidwa ndi silikoni kapena opangidwa ndi mafuta amchere) amasokoneza mapangidwe a thovu, kuchepetsa kupangika kwa thovu ndikuwonetsetsa kuti pamwamba pake pazikhala bwino, popanda chilema.

4. Kusintha kwa Leveling

The kusanja katundu zokutira zimatsimikizira kusalala ndi maonekedwe a zouma filimu. Malevel agents amagwira ntchito m'njira ziwiri zazikulu:

• Kuchepetsa kugwedezeka kwapansi: Kumawonetsetsa ngakhale kufalikira pazigawo, kuchepetsa zilema monga makanda alalanje kapena cratering.

• ​Modulating zosungunulira evaporation: Kutalikitsa nthawi yotuluka, kulola ❖ kuyanika mokwanira asanachiritse.

5. Antistatic Functionality

Muzinthu zamagetsi, zoyikapo, ndi zina, zokutira zimatha kudziunjikira zolipiritsa chifukwa cha mikangano, kuyika ziwopsezo zachitetezo. Antistatic antistatic (mwachitsanzo, cationic surfactants) adsorb yozungulira chinyezi kupanga conductive wosanjikiza pamwamba ❖ kuyanika, kutsogoza kutha kwacharge ndi kuchepetsa kuopsa kwa electrostatic.

6. Antimicrobial and fungicidal Protection

M'malo achinyezi, zokutira zimakonda kukula kwa tizilombo tating'onoting'ono, zomwe zimayambitsa kuwonongeka kwa filimu. Antimicrobial ndi fungicidal agents (mwachitsanzo, quaternary ammonium compounds) amalepheretsa kuchulukana kwa tizilombo toyambitsa matenda, kumawonjezera nthawi ya alumali ndi kukhazikika kwa ntchito zokutira.

7.Kukweza kwa Gloss ndi Kukweza kwa Slip

Zopaka zina zimafuna zowala kwambiri kapena zosalala (mwachitsanzo, mipando kapena zokutira zamafakitale). Zowonjezera gloss ndi zowonjezera zowonjezera (monga phula kapena ma silikoni) zimathandizira kuti filimuyo iwonetsere bwino ndikuchepetsa kugundana kwapamtunda, kumathandizira kuti musavalidwe komanso kumveka bwino.

Ma Surfactants amagwira ntchito zingapo pamakampani opanga zokutira, kuyambira pakuwongolera magwiridwe antchito mpaka kukweza filimu yomaliza, zonse zimagwiritsa ntchito luso lawo lapadera loyang'anira mawonekedwe. Ndikupita patsogolo kwa zokutira zokometsera zachilengedwe komanso zogwira ntchito kwambiri, zida zatsopano, zogwira mtima, komanso zotsika kawopsedwe zikhalabe zofunika kwambiri pakufufuza kwaukadaulo wamtsogolo.
