Iindidi zezongezo zokuMata ezisetyenziswa kwiPowder Coating okanye ipeyinti

Zine Iindidi zezongezo zokuMata ezisetyenzisiweyo Powder Coating Powder okanye Peyinta.

• Iisilika

Kwintsimi ebanzi yee-silicas ezifumanekayo zokudibanisa kukho amaqela amabini ahluke ngokwenkqubo yawo yokuvelisa. Enye yinkqubo ye-hydro-thermal, evelisa i-silicas ene-morphology ethambileyo. Ngokusebenzisa iimveliso zenkqubo ye-silica-gel zinokufumaneka ezine-morphology enzima. Zombini iinkqubo ziyakwazi ukuvelisa i-silica eqhelekileyo kwaye emva kweemveliso ezinyangweyo. Emva kokuba unyango luthetha ukuba umphezulu we-silica unokuguqulwa ngokuyinxenye kunye ne-organic (wax) okanye izinto ezingabonakaliyo. Xa kuthelekiswa ne-silica-gel matting agents, i-silica eguquliweyo inobungakanani bamasuntswana ahlukeneyo, ukuhanjiswa kobungakanani besuntswana, kumthamo wepore. I-Hydrothermal matting agents zihluke ngobukhulu be-particle kunye nokusabalalisa. Sisenokufumana izixhobo ezinganyangwanga kwaye zinyangwe. Okwangoku kukho imveliso enye kuphela ethandwayo kwisicelo esithile, eveliswa ngokwenkqubo yepyrogenic, kwaye ibonisa ukusebenza kakuhle okuphezulu kakhulu, ngokukodwa kwiinkqubo ezisekelwe emanzini.

I-Synthetic Aluminium silicates isetyenziswa kwiipeyinti ze-emulsion ikakhulu njenge-extender yomgangatho ophezulu ukuze ithathe indawo ye-Titandioxyd. Nangona kunjalo, zisenokusetyenziselwa ukunika isiphumo sokumata ngokulinganayo kwipeyinti eyomileyo ye-emulsion. Kwiinkqubo ze-oyile ezinde ze-Alkyd zisebenza njenge-agent yokudibanisa, kodwa kufuneka zihlakazwe nge-pigment kunye nezigcwalisi. I-silicas yokulinganisa isetyenziswa kwiinkqubo zokugquma zonke, nangona kungekhona kwiingubo zomgubo.

• Iimpungutye

Namhlanje, kukho uluhlu oluhlukeneyo lwe-wax kwimarike. Iiwax ezisetyenziswa kakhulu kwiingubo kunye neenki zisekelwe kwiPolyethylene, Polypropylene, Carnauba, Amid. Iimveliso ze-wax ezisekwe kwi-Polytetrafluorethylene PTFE zikwasetyenziswa njengee-agent zokukhwela.

Ngokwahlukileyo kwi-silicas, i-wax iguqula iipropati zomphezulu wefilimu yepeyinti ngokudada phezulu phezulu. Esi siganeko sichaphazela ezi mpawu zilandelayo: iqondo le-matt / gloss; ukutyibilika kunye nokuxhathisa; iipropathi zokunqanda kunye ne-abrasion, i-anti yokuhlalisa kunye noxinzelelo lomphezulu.

Uninzi lweemveliso zihanjiswa njengeemveliso ze-micronized, ezifumaneka kuluhlu olubanzi lwee-concentrates ezisekelwe kwi-wax emulsions. Ukusasazwa kuyahluka ngokobukhulu bamasuntswana kunye nokusabalalisa ubungakanani bamasuntswana.

• Iifilitha

Nangona ukubonakala kwepeyinti kutshintsha ngokudityaniswa kwezongezo ezikhankanywe ngaphambili, ukusebenza akuchaphazeleki. Ngokusebenzisa izihluzi ezithile sonyusa ngokucacileyo i-Pigment-Volume-Concentration yepeyinti ebandakanya zonke iziphumo ebezingalindelekanga ezithethwayo. Eso sizathu sokuba le ndlela yokulinganisa ithintelwe kuphela kwiinkqubo zepeyinti ezinemibala ephantsi, yoqoqosho.

Izigcwalisi ezinokuhanjiswa kwesayizi yesuntswana elincinci elikhethiweyo kufuneka lisasazeke kunye nee-pigments. Ukulungelelanisa isidanga seglosi efunekayo yipraksis ukuyilungisa ngokusebenzisa ukushukuma kwiSilica ekupheleni kwenkqubo yokuvelisa ipeyinti.

• Izinto Eziphilayo

Ngobuchule bale mihla bokugaya kuyakwazeka ukucola imathiriyeli yeplastiki esekwe ikakhulu kwipoly methyl urea resin. Iimveliso ezinjalo zinempembelelo ephantsi kwi-viscosity, zibonisa ukuzinza kweqondo lokushisa ukuya kwi-200 ° C, zine-resistive resistivity enhle ye-solvent, kwaye zilula ukusabalalisa.

Lilonke, Zonke izongezelelo zokudibanisa ezisetyenziswa kwi-powder coatings okanye ibala lepeyinti, zinezibonelelo kunye neenzuzo zazo.
