Kodi ufa wa utomoni ungalowe m'malo mwa ufa wa latex wotayikanso?

Monga surfactant yopanda ionic, hydroxyethyl cellulose ili ndi zinthu zotsatirazi kuwonjezera pa kukhuthala, kuyimitsa, kugwirizanitsa, kuyandama, kupanga mafilimu, kufalitsa, kusunga madzi ndi kupereka colloid yotetezera.Hydroxyethyl cellulose (HEC tonsefe Zimadziwika kuti hydroxyethyl cellulose HEC ndi hydroxypropyl methyl cellulose HPMC amagwiritsidwa ntchito pomanga, koma pali kusiyana kotani pakati pa zida ziwirizi?

Pamsika pali utomoni wambiri wa utomoni, mphira wamphamvu wosagwira madzi ndi zina zotsika mtengo za mphira kuti zilowe m'malo mwa emulsion yachikhalidwe ya VAE (vinyl acetate-ethylene copolymer) ndi ufa wowuma wowuma wowumanso, kenako utomoni kusiyana pakati pa ufa wa rabara ndi ufa wa latex wopangidwanso?Kodi ufa wa utomoni ungalowe m'malo mwa ufa wa latex wotayikanso?

Mtondo womanga ndi zinthu zomangira zomwe zimagwiritsidwa ntchito mochuluka komanso zogwiritsidwa ntchito mosiyanasiyana m'nyumba zamafakitale ndi anthu.Pali mitundu iwiri yokonzekera pamalowo ndikugulitsa matope omanga.Pakali pano, digiri ya malonda a matope m'mayiko otukuka ku Ulaya ndi United States kale kwambiri.Izi zili choncho chifukwa matumba osakaniza owuma kapena matope ambiri amatha kufulumizitsa nthawi yokonzanso malo omanga ndikuchepetsa ndalama zogwirira ntchito.Zogwirizana ndi maziko ndi zida Kusiyanasiyana kwa mitundu kumakulitsa luso la zomangamanga ndikuteteza chilengedwe.Mosiyana ndi matope omwe amasakanizidwa pamalopo, matope osakaniza owuma amapangidwa mwa kusakaniza zinthu zonse zofunika, monga cementitious material aggregates ndi zowonjezera mankhwala, pansi pa zikhalidwe zoyendetsedwa bwino za mankhwala enaake mu fakitale yamatope owuma.

Pokhala ndi M monga chothandizira pobowola matope ndi madzi otaya madzi, imatha kukana kuipitsidwa ndi mchere wosiyanasiyana wosungunuka.Matope omwe ali ndi M samakhudzidwa kawirikawiri ndi nkhungu, kotero sikoyenera kukhala ndi pH yamtengo wapatali ndikugwiritsa ntchito zotetezera.Kubowola matope ndi kuyimitsidwa kwina ndi kubalalitsidwa kumakhala ndi moyo wa alumali, kuwonjezera M kumatha kupangitsa kuti ikhale yokhazikika ndikutalikitsa moyo wa alumali.

Hydroxyethyl cellulose (HEC) ndi cellulose ether yosakhala ionic yopangidwa kuchokera ku cellulose yachilengedwe ya polima kudzera munjira zingapo za etherification.Ndiwopanda fungo, wopanda pake komanso wopanda poizoni ufa woyera kapena granule, womwe ukhoza kusungunuka m'madzi ozizira kuti ukhale wowonekera bwino, ndipo kusungunuka sikukhudzidwa ndi pH mtengo.Lili ndi makhalidwe a thickening, adhesion, kubalalitsidwa, emulsification, filimu kupanga, kuyimitsidwa, adsorption, ntchito pamwamba, kusunga madzi ndi kukana mchere.Amagwiritsidwa ntchito kwambiri mu utoto, zomangamanga, nsalu, mankhwala tsiku lililonse, mapepala, kubowola mafuta ndi mafakitale ena.

Zopangidwanso za latex powder ndi ufa wosungunuka m'madzi, womwe umagawidwa kukhala ethylene/vinyl acetate copolymers, vinyl acetate/tertiary carbonic acid ethylene copolymers, acrylic acid copolymers, etc., ndi zomatira za ufa zopangidwa pambuyo poyanika kutsitsi.Mowa wa polyvinyl umagwiritsidwa ntchito ngati colloid yoteteza.Mtundu uwu wa ufa ukhoza kufalikiranso mu emulsion mutatha kukhudzana ndi madzi.Chifukwa cha kuthekera kwakukulu kolumikizana komanso mawonekedwe apadera a ufa wopangidwanso wa latex, monga kukana madzi, kumanga ndi kutchinjiriza kutentha, ndi zina zambiri, kugwiritsa ntchito kwawo Kukula kwake ndikwambiri.
