Dispersing agent NNOinowanzoshandiswa mumunda wekupararira kwemakemikari, kureva, pendi, inki uye imwe pigment paste kugaya. Mukuwedzera, kuwedzera dispersant mu resin kana emulsion inogona kuvandudza kushanda kwemuviri mukuru. Basa guru nderokudzikisa donje, kudzivirira kunyura uye kubatsira kupararira. Zvitatu maitiro akakosha maitiro evanoparadzira uye anowanzo shandiswa kuzivaDispersing agent NNO!
Kutanga, kuderedza viscosity uye kuwedzera pigment mutoro. Kushandisa zvakakodzeraDispersing agent NNO, iyo paste viscosity yaizoderedzwa zvakanyanya. Mhedzisiro ndeyekuwedzera iyo pigment mutoro, kuvandudza kubereka kuita basa rakanaka.
Chechipiri, vanhu vazhinji vanodzikisira kugwamba nekuvandudza kuvaka kweinjiniya nekuita vanozoita bvunzo dzekutsvagisa kana vachiongorora makobvu. Kukanganisa kuparadzaniswa kwechigunwe, kubata kwemunwe uye kusabatwa zvikamu zvichaonekwa zvakajeka musiyano wemuvara, kugona kwemavara kweyakaomeswa pigment kuchaderedzwa, zvichikonzera matambudziko ekuvaka toner nependi. Condensation yemadziva emavara inogonawo kucherechedzwa nekuyerera kweplate kuyedza.
Chechitatu, kunatsiridza kujeka kana kuvharika. Kune pendi, iyo yakanyanya kujeka paste, zviri nani. Kune pendi yakawanda, iyo yakakwirira kufukidzwa kweuswa hwemavara, zviri nani. Kutaura zvazviri, zvine chokuita nekukura kwepigment. Imwe data inoratidza kuti kunze kwerefractive index, pendi particle size kugovera chimwe chinhu chakakosha chekubuda pachena. Sezvo saizi yechikamu ichiwedzera, kugona kuparadzira mwenje kunotanga kudzikira sezvainowedzera. Uku kugona kuparadzira mwenje kunosimudzira simba rekuputira re pigment, kana simba rekuparadzira rakasimba, uye kana saizi yechikamu ichiramba ichiwedzera, simba rekuputira rinoderera. Nekudaro, kana iyo pigment particle size iri pasi pehumwe kukosha, kujeka kuchawedzera sezvo saizi yechikamu inoderera. Dispersant haigone kushandura hunhu hwe pigment pachayo, asi inogona kudzora chidimbu saizi kugovera kwe pigment, kuti iwane yakanyanya kunaka mhedzisiro yemuvara.
Chii chinonzi wetting dispersant, wetting dispersant imhando ye surfactant ine hydrophilic uye lipophilic. Kunyanya isinganyungudike muzvinwiwa, chombo chinogona kuparadzira zvakaenzana zvimedu zvimedu muorganic pigment, zvichidzivirira zvimedu zvakasimba kubva pakugadzika nekuungana kuti zvigadzire maajenti anodiwa kudzikamisa kumiswa.
Saka yako yakanakira wetting dispersant ingaite sei?
Kana chiri chinhu chinonyanya kunyudza zvinhu zvakasimba mumvura. Deredza kudhonzerana kwepamusoro kana kudhonzerana kwechiso kuitira kuti mvura ipararire pamusoro kana kupinda mukati mechinhu chakasimba, nokudaro ichinyorovesa chinhu chakasimba. Uye kazhinji pamusoro rinoshanda mumiririri, akadai sipo, sulfonated mafuta, upfu uye zvichingodaro. Iwe unogona zvakare kushandisa soy lecithin, acetylene, mercaptan, mercaptan acetal, nezvimwe.
Ose ari maviri anorasa mvura
1. Adsorb pamusoro pezvikamu zvakasimba kuita kuti nzvimbo yakakomberedzwa yezvikamu zvakasimba zvinyorove.
2. Nzvimbo yezvimedu zvakasimba inoumba adsorption layer kuti iwedzere kuchaja pamusoro pezvimedu zvakasimba uye kuvandudza simba rekuita pakati pezvikamu zvinoumba zvipingamupinyi zvitatu-dimensional.
3. Ita pamusoro pezvimedu zvakasimba kuti zvigadzire chimiro chebilayer, kunze kwemvura yakapararira ine hukama hwakasimba, kuwedzera chiyero chezvikamu zvakasimba zvakanyorova nemvura. Solid particles anoparadzaniswa ne electrostatic repulsion.
4. Uniform system, kunatsiridza kumiswa kwekuita, hapana kunaya kwemvura, zvemuviri uye zvemakemikari zvimiro zvehurongwa hwese hwakafanana.
