Hydroxyethyl Cellulose Ether

Hydroxyethyl cellulose ether, isiri-ionic pamusoro inoshanda chinhu, inowanzoshandiswa cellulose ether organic water-based ink thickener. Iyo inonyungudika nemvura isiri-ionic komboni uye ine yakanaka kukobvu kugona kumvura.

Iine maitiro akawanda akadai sekukora, kuyangarara, kusungira, emulsifying, firimu-kuumba, kuisa pfungwa, kuchengetedza mvura kubva pakubuda, kuwana uye kuve nechokwadi chekushanda kwezvikamu, uye inewo zvakawanda zvakakosha.

Dispersant

Disperant is a surfactant ine maviri akatarisana zvimiro zve lipophilicity uye hydrophilicity mumorekuru. Inogona kuparadzira zvakaenzana zvimedu zvakasimba uye zvemvura zve inorganic uye organic pigments zvakaoma kunyunguduka mumvura, uye panguva imwe chete kudzivirira zvimedu kubva pakugadzirisa uye kuwirirana, zvichiita amphiphilic agent inodiwa kuti imiswe yakagadzikana.

Iine dispersant, inogona kuvandudza kupenya, kudzivirira iyo inoyangarara ruvara, uye kunatsiridza simba rekuita. Ziva kuti iyo tinting simba haina kukwirira sezvinobvira mune otomatiki coloring system, kuderedza viscosity, kuwedzera kurodha kwe pigment, nezvimwe.

Wetting agent

Iyo yekunyorovesa mumiriri inotamba basa ranguard mune yekupfekedza sisitimu, iyo inogona kusvika pamusoro peiyo substrate kutanga "kugadzira mugwagwa", uye ipapo iyo firimu-inogadzira chinhu inogona kuparadzirwa munzira "nzira" iyo yekunyorova yakafamba. Mumvura-based system, iyo yekunyorovesa agent yakakosha zvikuru, nekuti kudzvinyirirwa kwepamusoro kwemvura kwakakwirira kwazvo, kunosvika 72 dynes, iyo yakanyanya kukwirira kupfuura tension yepasi pe substrate. Kupararira kuyerera.

Antifoaming agent

Defoamer inonziwo defoamer, antifoaming agent, uye foaming agent zvinoreva kubvisa furo. Icho chinhu chine kuderera kwepasi tension uye yakakwirira pamusoro pekuita, iyo inogona kudzvanya kana kubvisa furo muhurongwa. Mafuro mazhinji anokuvadza achagadzirwa mukugadzirwa kwemaindasitiri, izvo zvinokanganisa zvakanyanya kufambira mberi kwekugadzira. Panguva ino, zvakakosha kuwedzera defoamer kubvisa aya anokuvadza furo.

Titanium dioxide

Indasitiri yependi ndiyo inonyanya kushandisa titanium dioxide, kunyanya rutile titanium dioxide, yakawanda iyo inopedzwa neindasitiri yependi. Iyo pendi yakagadzirwa netitanium dioxide ine mavara akajeka, simba rekuhwanda rakakwirira, simba retinti rakasimba, dosage shoma, uye marudzi akawanda. Inogona kuchengetedza kugadzikana kwepakati, uye inogona kuwedzera simba remagetsi uye kunamatira kwefirimu yepende kudzivirira kuputika. Inodzivirira mwaranzi yeUV uye hunyoro kubva mukati, kuwedzera hupenyu hwefirimu repende.

Kaolin

Kaolin imhando yekuzadza. Kana yakashandiswa mukuputira, mabasa ayo makuru ndeokuti: kuzadza, kuwedzera kuwanda kwefirimu yepende, kuita kuti firimu yepende iwedzere uye yakasimba; kuvandudza kupfeka kusagadzikana uye kusimba; kugadzirisa maitiro e optical of the coating, kuchinja Kuonekwa kwefirimu yekuputira; sekuzadza mukuputira, inogona kuderedza huwandu hweresin inoshandiswa uye kuderedza mutengo wekugadzira; inobata basa rinotungamirira mumakemikari emufirimu wekuputira, zvakadai sekusimudzira anti-rust uye flame retardancy.

calcium yakawanda

Kana heavy calcium inoshandiswa mukati mekuvaka pendi, inogona kushandiswa yoga kana kusanganiswa netalcum powder. Kuenzaniswa netalc, inorema calcium inogona kuderedza chiyero chechalking, kuvandudza kuchengetwa kwemavara ependi ine mavara akajeka uye kuwedzera kuramba kuumbwa.

Lotion

Basa re emulsion nderokuvhara pigment uye filler mushure mekugadzirwa kwefirimu (upfu hune simba rakasimba rekuisa ruvara ndiyo pigment, uye hupfu husina kukwanisa kuisa ruvara) kudzivirira kubviswa kwehupfu. Kazhinji, styrene-acrylic uye pure acrylic emulsions inoshandiswa kunze kwemadziro. Styrene-acrylic inodhura-inoshanda, inoshanduka yero, yakachena acrylic ine yakanaka yemamiriro ekunze kuramba uye kuchengetedza kwemavara, uye mutengo wakakwira zvishoma. Pendi dzekunze dzegiredhi rekunze dzinowanzoshandisa styrene-acrylic emulsions, uye pakati-kusvika-yepamusoro-yekupedzisira ekunze emadziro pendi kazhinji anoshandisa pure acrylic emulsions.

Pfupisa

Mukugadzirwa kwekuputira, zvinoshanda zvekubatsira zvinhu zvakadai sekuchengetedza uye thickeners zvinowedzerwawo.

Izvo zviri pamusoro ndezvokuumbwa kwekuongorora kwepende mbishi zvinhu. Nekuenderera mberi kwekusimudzira hupfumi, zvinodiwa nevanhu zvekupfeka zvinogara zvichichinja. Pachave nezvimwe zvinoshamisa zvakatimirira mumusika wependi weramangwana!
