Mitundu ndi kugwiritsa ntchito kwa okonda zofananira pamawu ojambula pamadzi

1. Inric

Otsanulira ochulukirapo ndi mtundu wa mchere wa gel womwe umatha kuyamwa madzi ndi kutupa, komanso mtundu wa osinthika, koma utoto wosawuka umangokhala katundu. Nthawi zambiri imagwiritsidwa ntchito molumikizana ndi cellulose kapena ma primers ndi zotupa. Pangani utoto waukulu.

2. Cellulose Thicker

Cellulosic thickeners are an important thickener with a long history of application and a wide range of applications, mainly including hydroxymethyl cellulose, hydroxyethyl cellulose, and hydroxypropyl cellulose, of which hydroxyethyl cellulose It is the most widely used and was once the mainstream of thickeners.

Poyerekeza ndi ma trailose okulitsa ma cellose ali ndi maubwino okwanira kukula kwamphamvu, kulingalira bwino ndi makina ogwiritsira ntchito mogwirizana, mphamvu zapamwamba za PH pa Iscctonion, ndipo zimapangitsa kuti zisumbu. Maubwino, koma kugwiritsa ntchito ma cellulose kulinso ndi zolakwika zazikulu, makamaka pazotsatira.

A. Magwiridwe antchito a hai-Mombe ndi osauka. Cellulose Thickener ndi gawo lachilengedwe, lomwe limakhala pachiwopsezo cha kuukira, zomwe zimapangitsa kuchepa kwa mafakisi. Ili ndi zofunikira pa zopanga ndi malo osungira.

B. Kukhazikitsa, mothandizidwa ndi kupsinjika kwa shear, hydration wosanjikiza pakati pa Thickener ndi madzi kuwonongedwa ndi utoto wa latex, zomwe ndizosavuta kupanga. Pambuyo pa zokololazo zitamalizidwa, kuwonongedwa kwa madzi a hydration osanjikiza nthawi yomweyo, ndipo ma utoto amachira mwachangu ndipo utoto suli wokhoza bwino, zomwe zimapangitsa kutsuka kapena kumangika.

C. Kuwaza. Pa ntchito yomanga ikuyenda bwino, tinthu tating'onoting'ono totopeyo nthawi zambiri zimapangidwa potuluka pakati pa odzigudubuza ndi gawo lapansi, lomwe limatchedwa Atomization; Panthawi yopuma-yothamanga, imatchedwa kuti ikuwaza.

D. Matumba omasulira amatha kuyambitsa kukwera kwa malo a ma cell a latch, amakhudza kukhazikika kwa zokutirako, ndikuyambitsa bushnar.

3.. Polyaciry

Ouzira Polyacry amatha kugawidwa m'mitundu iwiri: imodzi ndi polyacrytete wamadzi; Wina ndi homepolymer kapena comprolimer emulsion tricker ya acrylic acid ndi methacrylic acid.

Inchinyo yokha ndi acidic ndipo imayenera kuphatikizidwa ndi alkali kapena madzi ammoni wa pH yamtengo wa 8-9 kuti apange kukula. Amatchedwanso acrylic acid alkali kutupa.

Amadalira makamaka ma electostatic anion of carboxt assion osungunuka pansi pa alkalines kuti apangitse unyolo watambasulira ndodo ndi kunenepa, ndipo PH imayenera kutsogoleredwa kuposa 7.5.

Acrylic Thickener ndi anionic, ndipo madzi ake kukana ndi alkali akutsutsana ndi osauka. Poyerekeza ndi mabatani okutira a cellulosic, ali ndi katundu wabwino komanso odana ndi kuwaza, ndipo samatha kugwiritsidwa ntchito pazithunzi zonyezimira.

4.. Polyurethane Thickener

Poyerekeza ndi ma cellulose omwe tafotokozapo a cellose ndi acrylic okulitsa aclic, oureurethane ali ndi maubwino otsatirawa:

A. Zonse zobisala komanso zosunga bwino.

B. Kulemera kochepa pang'ono, osati kosavuta kutulutsa sprash mukamadzigudubuza.

C. Imatha kuyanjanitsa ndi tinthu tating'onoting'ono popanda kukwera pang'ono, kuti zipangitse kuti filimuyo ili ndi plass yapamwamba;

D. Zabwino hydrophobicity, kukana kwa scrub, kukana madambo ndi kukhazikika kwachilengedwe.

Oureurethane Otsatsa a Polyiretha ali ndi chidwi ndi kapangidwe ka fomula, ndipo kusintha kwawo sikwabwino ngati ma traulose. Mphamvu za zinthu zosiyanasiyana ziyenera kulingaliridwa kwathunthu mukamagwiritsa ntchito.

Pali mitundu yambiri ya oba. Posankha kuzigwiritsa ntchito, kuchita bwino ndi chidwi pa chizolowezi ziyenera kuonedwa koyamba, komanso chidwi chomanga, mawonekedwe a filimu yokutidwa ndi kukhazikika kuyenera kulingaliridwa kachiwiri.
