Mashandisiro Aungaita HEC mu Latex Pendi

1. Sumo

HydroxytHyl Cellulose (Hek) is is is is is is-ionic mvura-yekunyungudika-inoshandiswa pakunyanyisa mumakonzo, minda yemafuta, mitezo, mapepa uye mamwe maindasitiri. Iyo ine yakanakisa kuremerwa, yemuchero, firimu-fomu yekugadzira, kupararira, kusimbisa uye mamwe mabasa, uye anoita basa rakakosha muPendi yeLatex.

2. Hunhu hwe hydroxythyl cellulose

Kukakavara: Hec ine yakanaka kwazvo kugona, iyo inogona kuwedzera iyo viscosity yeLatex Paint, nokudaro kuvandudza mashandiro ayo ekuvaka.
Rheology: Hec inogona kugadzirisa iyo rheology yeLatex Pendi, inopa yakanakisa anti-sagging uye kugeza zvinhu.
Kumiswa: Inogona kudzivisa zvinobudirira panzi uye mafirita kubva pakugadzirisa panguva yekuchengetedza uye kuvaka.
Firimu-fomu
Kugadzikana: Hec ine yakanaka yemakemikari kugadzikana uye kugadzikana kwezvinhu zvakasikwa, uye kunogona kuchengetedza maitiro akagadzikana pasi pemamiriro akasiyana emamiriro ekunze.

3. Ungashandise sei hydroxytHyl cellulose mune latex pendi

Nzira yekunyungudika
Hec inoda kunyungudutswa mumvura usati washandiswa kuumba yunifomu mhinduro. Matanho emagetsi ekupaza anotevera:
Kuyera: kuyera iyo inodiwa hec zvinoenderana nezvinodiwa formula.
Preemixing: Zvishoma nezvishoma Wedzera HEC kumvura inotonhora uye premix kudzivirira Agglomeration.
Kukurudzira: Simbisa neyakaomarara-kumhanya kwemaminitsi makumi matatu kusvika 1 awa kuti ive nechokwadi chekuti hec haina kunyungudika zvachose.
Kurohwa: Rega mhinduro yacho kwemaawa akati wandei kusvika maawa makumi maviri nemana kusvika paec isimbe zvizere kuti aumbe yunifomu Glue Solution.
Kugadzirira Latex Paint
Mukutonga kwekugadzira yeLatex Paint, hec Solution inowanzowedzerwa mugadziriro yekugadzirira. Maitiro akajairika ari seinotevera:
Burnse pigment uye mafirita: Mukuparadzira nzvimbo, kuparadzira nhandare yemubatanidzwa wemvura, wedzera huwandu hwakakodzera hwekuparadzira, uye uchipararira pakumhanya kwakadzika kusvikira pigment uye mafirita akaparadzirwa zvakakwana.
Wedzera hold Solution: zvishoma nezvishoma wedzera iyo pre-pre-prec solution pasi peyakaderera-kumhanya kumhanyisa kuti ive nechokwadi chekusanganisa yunifomu.
Wedzera emulsion: Zvishoma nezvishoma wedzera emulsion pasi pekumutsa uye kuramba uchimutsa kuti uve nechokwadi chekupararira yunifomu.
Gadzirisa viscosity: Wedzera yakakodzera huwandu hwehukadzi kana mvura sezvinodiwa kugadzirisa viscosity yekupedzisira yeLatex pendi.
Wedzera zvinodhaka: Wedzera mamwe mahwira akadai se defoamer, chengetedza, firimu-kugadzira rubatsiro, nezvimwe zvinoenderana neform zvinodiwa.
Simptly: Ramba uchimutsa kuti uve nechokwadi chekuti zvikamu zvese zvakanyanyisa kusanganiswa kuti uwane yunifomu uye yakagadzikana langax pendi.

Zvekungwaririra
Paunenge uchishandisa HEC, pfungwa dzinotevera dzinofanira kucherechedzwa:
Kupisa tembiricha: Hec iri nyore kunyungudika mumvura inotonhora, asi yakanyanya kupisa ichakonzera iyo yekunyoroveswa ichatsanya kutsanya, kuumba agglomoterates, inokanganisa mashandiro ekushandisa.
Kumhanyisa kumhanya: Munguva yekufungidzira uye kumutsa, kumhanya hakufanirwe kutsanya zvakanyanya kudzivirira bubbles rakawandisa.
Mamiriro ekuchengetedza: Hec Solution inofanirwa kunge yakagadzirirwa usati washandiswa kudzivirira kuchengetedza kwenguva refu kudzivirira biodergradation uye viscosity kuderedzwa.
Fomula kugadzirisa

Semunhu akakosha akakosha uye rheology modifier, hydroxylyl cellulose anotamba chinzvimbo chisina kujairika muLatex pendi. Kuburikidza nekunyoreswa kushungurudzika uye kuwedzera nzira, kuita kweiyo Latex Paint inogona kuvandudzwa zvakanyanya, kupa zvakanaka maitiro ekuvaka uye pendi yemhando yefirimu. Mukugadzirwa chaiko, kushandiswa kwehisheni kunofanirwa kuve kwakachinjika zvinoenderana nenzira yakatarwa yemafomu uye maitiro ekuti uwane zvakanakisa kushandiswa kwakanakisa.
