Ndi zinthu ziti zosungunulira zomwe zingagwiritsidwe ntchito kuwongolera thovu poyeretsa?

Ma surfactants otsika thovu amaphatikizapo mankhwala angapo osakhala a ionic ndi amphoteric omwe ali ndi mphamvu zambiri zogwirira ntchito komanso kuthekera kogwiritsa ntchito. Ndikofunikira kudziwa kuti ma surfactants awa si othandizira thovu. M'malo mwake, kuwonjezera pa zinthu zina, amapereka njira yowongolera kuchuluka kwa thovu lomwe limapangidwa mu ntchito zina. Ma surfactants otsika thovu amasiyananso ndi ma defoamers kapena antifoamers, omwe ndi zowonjezera zomwe zimapangidwa makamaka kuti zichepetse kapena kuchotsa thovu. Ma surfactants amapereka ntchito zina zofunika kwambiri popanga zinthu, kuphatikizapo kuyeretsa, kunyowetsa, kusakaniza, kufalitsa, ndi zina zambiri.

Mankhwala Opangira Ma Surfactants a Amphoteric​

Ma amphoteric surfactants okhala ndi ma profiles otsika kwambiri a thovu amagwiritsidwa ntchito ngati ma surfactants osungunuka m'madzi m'njira zambiri zoyeretsera. Zosakaniza izi zimapereka mphamvu zolumikizira, kukhazikika, kuyeretsa, komanso kunyowetsa. Ma surfactants atsopano a amphoteric okhala ndi ntchito zambiri amakhala ndi mawonekedwe otsika kwambiri a thovu pomwe amapereka magwiridwe antchito oyeretsa, mawonekedwe abwino kwambiri a chilengedwe ndi chitetezo, komanso kugwirizana ndi ma surfactants ena osakhala a ionic, cationic, ndi anionic.

Ma Alkoxylates Osakhala a Ionic​

Ma alkoxylate otsika-thovu okhala ndi ethylene oxide (EO) ndi propylene oxide (PO) amatha kutsuka bwino komanso kupopera mankhwala otsukira pogwiritsa ntchito makina ambiri. Zitsanzo zikuphatikizapo zida zotsukira zotsukira mbale zokha, zotsukira mkaka ndi chakudya, zotsukira zamkati ndi mapepala, mankhwala opangira nsalu, ndi zina zambiri. Kuphatikiza apo, ma alkoxylate okhala ndi mowa amakhala ndi mphamvu zochepa zotulutsa thovu ndipo amatha kuphatikizidwa ndi zinthu zina zochepa zotulutsa thovu (monga ma polima osungunuka m'madzi) kuti apange zotsukira zotetezeka komanso zotsika mtengo.

Ma Copolymer a EO/PO Block​

Ma EO/PO block copolymers amadziwika ndi mphamvu zawo zabwino zonyowetsa ndi kufalitsa. Mitundu ya thovu lochepa m'gululi ingagwiritsidwe ntchito ngati ma emulsifiers ogwira ntchito zosiyanasiyana zoyeretsera m'mafakitale ndi m'mabungwe.

​Ma Amine Oxides Otsika a Thovu

Ma amine oxides okhala ndi miyeso yotsika kwambiri ya thovu amadziwikanso chifukwa cha ntchito yawo yoyeretsa mu sopo ndi degreasers. Akaphatikizidwa ndi ma hydrogels amphoteric okhala ndi thovu lochepa, ma amine oxides amatha kukhala ngati msana wa surfactant m'njira zambiri zotsukira malo olimba okhala ndi thovu lochepa komanso ntchito zotsukira zitsulo.

Ma Ethoxylates a Linear Alcohol​

Ma ethoxylates ena a mowa wolunjika amakhala ndi thovu lapakati mpaka lotsika ndipo angagwiritsidwe ntchito poyeretsa malo olimba osiyanasiyana. Ma surfactants awa amapereka mphamvu zabwino zoyeretsera ndi kunyowetsa pamene akusunga mawonekedwe abwino a chilengedwe, thanzi, ndi chitetezo. Makamaka, ma ethoxylates a mowa wochepa a HLB amakhala ndi thovu lochepa mpaka lochepa ndipo amatha kuphatikizidwa ndi ma methoxylates a mowa wochuluka wa HLB kuti athetse thovu ndikuwonjezera kusungunuka kwa mafuta m'mafakitale ambiri oyeretsera mafakitale.

Mafuta a Amine Ethoxylates​

Ma ethoxylates ena a fatty amine ali ndi mphamvu zochepa zotulutsa thovu ndipo angagwiritsidwe ntchito pa ntchito zaulimi ndi kuyeretsa kokhuthala kapena kupanga sera kuti apereke mphamvu zosungunulira, kunyowetsa, ndi kufalitsa.
