Ndi ma surfactants ati omwe angagwiritsidwe ntchito kuwongolera thovu pakuyeretsa?

Ma surfactants omwe ali ndi thovu lotsika amaphatikiza mitundu ingapo ya nonionic ndi amphoteric yokhala ndi magwiridwe antchito ambiri komanso mwayi wogwiritsa ntchito. Ndikofunika kuzindikira kuti ma surfactants awa samatulutsa thovu paziro. M'malo mwake, kuwonjezera pa zinthu zina, amapereka njira zowongolera kuchuluka kwa thovu lomwe limapangidwa muzofunsira zina. Otsika-foam surfactants amasiyananso ndi defoamers kapena antifoamers, zomwe ndi zowonjezera zomwe zimapangidwira kuchepetsa kapena kuthetsa thovu. Ma Surfactants amapereka ntchito zina zambiri zofunika pakupanga, kuphatikiza kuyeretsa, kunyowetsa, emulsifying, kubalalitsa, ndi zina zambiri.

Amphoteric Surfactantsku

Ma amphoteric surfactants okhala ndi foam yotsika kwambiri amagwiritsidwa ntchito ngati osungunuka m'madzi m'mapangidwe ambiri oyeretsa. Zosakaniza izi zimapereka kugwirizana, kukhazikika, kuyeretsa, ndi kunyowetsa katundu. Ma Novel multifunctional amphoteric surfactants amawonetsa kutulutsa thovu pang'ono pomwe akupereka ntchito yoyeretsa, mbiri yabwino ya chilengedwe ndi chitetezo, komanso kuyanjana ndi ma nonionic, cationic, ndi anionic surfactants.

Nonionic Alkoxylatesku

Ma alkoxylates otsika kwambiri okhala ndi ethylene oxide (EO) ndi propylene oxide (PO) amatha kupereka ntchito yabwino kwambiri yotsuka ndi kutsukidwa ndi kupopera mbewu mankhwalawa pamakina angapo othamanga kwambiri komanso oyeretsa makina. Zitsanzo ndi monga zothandizira kutsuka mbale, zotsukira mkaka ndi zakudya, zopangira zamkati ndi mapepala, mankhwala opangira nsalu, ndi zina zambiri. Kuphatikiza apo, ma alkoxylates opangidwa ndi mowa amawonetsa zinthu zotsika kwambiri ndipo amatha kuphatikizidwa ndi zinthu zina zopanda thovu (mwachitsanzo, ma polima osungunuka m'madzi) kuti apange zotsukira zotetezeka komanso zachuma.

EO/PO Block Copolymersku

EO/PO block copolymers amadziwika chifukwa chonyowetsa komanso kubalalika kwawo. Mitundu yotsika kwambiri ya thovu yomwe ili mgululi imatha kukhala ngati emulsifiers yogwira ntchito zosiyanasiyana zamafakitale ndi mabungwe.

kuLow-Foam Amine Oxides

Ma amine oxide okhala ndi miyeso yotsika kwambiri ya thovu amadziwikanso chifukwa choyeretsa mu zotsukira ndi zochotsera mafuta. Akaphatikizidwa ndi ma amphoteric hydrogel otsika, ma amine oxides amatha kukhala ngati msana wapambuyo pamapangidwe ambiri otsukira pansi opanda thovu olimba komanso oyeretsa zitsulo.

Linear Mowa Ethoxylatesku

Ma ethoxylates ena amzere amawonetsa thovu lapakati mpaka lotsika ndipo amatha kugwiritsidwa ntchito poyeretsa molimba pamtunda. Ma surfactants awa amapereka zabwino zotsuka komanso zonyowetsa kwinaku akusunga mbiri yabwino ya chilengedwe, thanzi, ndi chitetezo. Makamaka, otsika-HLB mowa ethoxylates ndi otsika kuti amatulutsa thovu ndipo amatha kuphatikizidwa ndi high-HLB mowa methoxylates kulamulira thovu ndi kumapangitsanso kusungunuka kwa mafuta m'mapangidwe ambiri oyeretsa mafakitale.

Mafuta a Amine Ethoxylatesku

Mafuta ena a amine ethoxylates amakhala ndi thovu lochepa kwambiri ndipo amatha kugwiritsidwa ntchito pazaulimi ndi kuyeretsa kokhuthala kapena kupangidwa ndi sera kuti apereke emulsifying, kunyowetsa, ndi kubalalitsa katundu.
