Mhando dzeMatting Additives Anoshandiswa MuPowder Coating kana Paint

Kune mana Marudzi eMatting additives Anoshandiswa Mu Powder Coating Powder kana Paint.

• Silika

Mumunda wakafara we silicas inowanikwa yekuisa kune mapoka maviri anosiyana maererano nemaitiro avo ekugadzira. Imwe ndeye hydro-thermal process, iyo inoburitsa silicas ine yakapfava morphology. Nekushandisa silica-gel process zvigadzirwa zvinogona kuwanikwa izvo zvine yakaoma morphology. Maitiro ese ari maviri anokwanisa kugadzira yakajairwa silica uye mushure mekurapwa zvigadzirwa. Mushure mekurapwa zvinoreva kuti iyo silica pamusoro inogona kugadziridzwa zvishoma ne organic (wax) kana inorganic zvinhu. Kuenzaniswa nesilica-gel matting agents, silica yakagadziridzwa ine saizi yakasiyana, saizi yekugovera, muhuwandu hwepore. Hydrothermal matting agents akasiyana muhukuru uye kugovera. Tinogona zvakare kuwana zvinhu zvisina kurapwa uye zvakarapwa. Parizvino pane chigadzirwa chimwe chete chakakurumbira kune chaiyo application, iyo inogadzirwa zvinoenderana nepyrogenic process, uye inoratidza yakanyanya kukwirira matting kunyatsoita, kunyanya mumvura-yakavakirwa masisitimu.

Synthetic Aluminium silicates inoiswa mu emulsion pendi zvakanyanya seyepamusoro mhando yekuwedzera kutsiva imwe Titandioxyd. Nekudaro, ivo vanogona zvakare kushandiswa kupa yakaenzana yakaenzana matting maitiro muakaomeswa emulsion pendi. Mumafuta marefu Alkyd masisitimu anoshanda seanomira, asi anofanirwa kuparadzirwa ne pigment uye mafiritsi. Matting silicas anoshandiswa mune ese-yekuputira masisitimu, asi kwete muhupfu hwekuputira.

• Waxes

Nhasi, kune mhando dzakasiyana dzewakisi pamusika. Mawakisi anonyanya kushandiswa ekupfekedza uye ingi anobva paPolyethylene, Polypropylene, Carnauba, Pakati. Waxes zvigadzirwa zvakavakirwa paPolytetrafluorethylene PTFE zvinoshandiswawo semating agents.

Kusiyana nemasilica, wakisi inoshandura chimiro chepamusoro chefirimu repende nekuyangarara kumusoro kwepamusoro. Ichi chiitiko chinokanganisa zvinhu zvinotevera: dhigirii yematt / gloss; slip uye mar resistance; anti blocking uye abrasion zvivakwa, anti kugadzirisa uye kushushikana kwepasi.

Zvizhinji zvezvigadzirwa zvinounzwa sezvigadzirwa zvemicronized, izvo zvinowanikwa muhuwandu hwakasiyana-siyana hwekutarisa hwakavakirwa pane wax emulsions. Dispersions inosiyana zvichienderana nehukuru hwe particle uye particle size distribution.

• Vanyori

Kunyangwe kutaridzika kwependi kuchichinja kuburikidza nekuwedzera kweakambotaurwa matting additives, kuita hakuna kukanganiswa. Nekushandisa chaiwo mafirita isu tinowedzera zvakajeka iyo Pigment-Volume-Concentration yependi inosanganisira nese mhedzisiro yainoreva. Ndicho chikonzero nei iyi nzira yekuisa inogumira kune chete pigmented, ehupfumi makirasi epasi pendi masisitimu.

Iwo mafirita ane akasarudzika akatetepa particle size kugovera anofanirwa kupararira pamwe chete ne pigment. Kugadzirisa inodiwa gloss dhigirii ndeye praxis kuigadzirisa nekushandisa kumutsa muSilica pakupera kwemaitiro ekugadzira pendi.

• Organic Materials

Nemaitiro emazuva ano ekukuya zvinokwanisika kukuya zvinhu zvepurasitiki zvichibva paPoly methyl urea resin. Zvigadzirwa zvakadaro zvine simba rakaderera pane viscosity, zvinoratidza kugadzikana kwekushisa kusvika ku200 ° C, vane zvakanaka solvent resistivity, uye zviri nyore kuparadzira.

Zvese mune zvese, Yese madhidhi ekuwedzera ayo anoshandiswa muhupfu hwekuputira kana pendi munda, ane mabhenefiti uye zvakanakira.
