Nhanganyaya
Paint adhesion chinhu chakakosha chekuputira maapplication, achipesvedzera hupenyu hurefu uye kusimba kwenzvimbo dzakapendwa. Hydroxypropyl methylcellulose (HPMC) thickener additives akawana mukurumbira mukusimudzira kunamatira kwependi nekuda kwekugona kwavo kugadzirisa rheological zvimiro uye kunatsiridza kuita kwekupfeka.
Kunzwisisa HPMC Thickener Additives
HPMC i polymer inoshanda zvakasiyana-siyana inotorwa kubva ku cellulose, inopa yakanakisa kuchengetedza kwemvura uye kukora zvivakwa mune aqueous mhinduro. Kana yakasanganiswa mukugadzirwa kwependi, HPMC inoumba network network inopa viscosity uye kugadzikana kune pendi. Pamusoro pezvo, HPMC inodyidzana nezvimwe zvikamu zvependi, ichisimudzira kunamatira kune substrates nekusimudzira kunyorova kwakaringana uye kuumbwa kwemafirimu.
Kugadzirisa Magadzirirwo Maparamita
Kushanda kweHPMC thickener additives mukunamira pendi kunobva pane akati wandei ekugadzira paramita, kusanganisira mhando uye kusungirirwa kweHPMC, solvent kuumbwa, pigment dispersion, uye pH mazinga. Vagadziri vanofanirwa kuitisa bvunzo dzekuenderana kuti vaone iyo yakakwana dhizaini yemashandisirwo ekupfeka. Kugadzirisa aya ma paramita anogona kukwirisa rheological zvimiro zvependi uye kuve nechokwadi chekunamatira yunifomu kune akasiyana ma substrates.
Kugadzirira kwe Substrate Surface
Kugadzirira kwakakodzera kwepamusoro kwakakosha pakusimudzira kunamatira kwepende uye kudzivirira kutadza nguva isati yakwana. Usati waiswa, ma substrates anofanirwa kucheneswa, kucheneswa, uye, kana zvichidikanwa, kutariswa kuti abvise zvinosvibisa uye kugadzira nzvimbo inogoneka yekunamatira. Mechanical nzira dzakaita sejecha kana kuputika kweabrasive dzingashandiswa kunatsiridza kukwasharara kwepamusoro uye kunatsiridza kupindirana kwemichina pakati pepende nesubstrate.
Maitiro ekushandisa
Nzira dzinoverengeka dzekushandisa dzinogona kushandiswa kuwedzera mabhenefiti eHPMC thickener additives mukusimudzira kunamatira pendi:
Brush uye Roller Kushandisa: Kukwesha kana kutenderedza pendi pane substrate kunobvumira kunyatso kudzora pamusoro pekukora kwekuputira uye kunovimbisa kuvharika kwakakwana. Iko kushandiswa kwemhando yepamusoro mabhurashi uye rollers kunobatsira kuwana yunifomu kugovera kweHPMC-yakakora pendi, inosimudzira adhesion uye firimu kuumbwa.
Kupfapfaidza Chikumbiro: Spray application inopa mabhenefiti maererano nekumhanya uye kushanda nesimba, kunyanya kune hombe nzvimbo dzepamusoro kana yakaoma geometries. Kurongeka kwakaringana kwema paramita ekupfapfaidza senge kudzvanywa, saizi yenozzle, uye kona yekupfapfaidza kwakakosha kuti uwane yakakwana pendi deposition uye substrate wetting.
Kunyudza Coating: Kunyudza kupfekedza kunosanganisira kunyudza substrate mukugezera yeHPMC-yakakora pendi, kuve nechokwadi chekuvharika kwese kwese, kusanganisira nzvimbo dzakaoma-kusvika. Iyi tekinoroji inowanzoshandiswa mumaindasitiri akadai semotokari uye simbi kupedzisa, uko yunifomu yekunamatira uye kushora kuramba kwakakosha.
Electrostatic Coating: Electrostatic coating inoshandisa kukwezva kwemagetsi kuisa pendi zvimedu pane substrate, zvichikonzera kunama uye kuvharika. HPMC-yakakora pendi inogona kugadzirwa ye electrostatic application, ichipa yakagadziridzwa kutamisa kushanda zvakanaka uye kuderedza overspray.
Mafungiro ePost-Application
Mushure mekushandisa pendi, kurapa kwakakodzera uye kuomeswa mamiriro anofanirwa kuchengetedzwa kuti afambise kuumbwa kwemafirimu uye kukwenenzvera adhesion zvivakwa. Kupinda mhepo kwakaringana, kudzora tembiricha, uye nguva yekurapa zvinhu zvakakosha zvekufunga nezvayo, kuve nechokwadi chekuvandudzwa kwejira rinogara uye rinonamatira.
Hydroxypropyl methylcellulose (HPMC) thickener additives inopa mabhenefiti akakosha mukunamira pendi uye kuita kwekupotera. Nekugadzirisa maparamendi ekugadzira uye kushandisa nzira dzakakodzera dzekushandisa, vagadziri vanogona kukwidziridza kugona kweHPMC kuwana kunamatira kwepamusoro pane akasiyana substrates. Kuisa mari mukugadzirira kwepamusoro, kusarudza nzira dzekushandisa dzakakodzera, uye kuve nechokwadi chekurapa kwakakwana matanho akakosha mukuwedzera kushanda kweHPMC thickener additives mukusimudzira kunamatira kwependi.
