Zvinhu zvinoenzanisa mazingaZvinoshandiswa mukupenda zvinowanzoiswa muzvikamu zve mixed solvents, acrylic acid, silicone, fluorocarbon polymers uye cellulose acetate. Nekuda kwehunhu hwayo hwekusimba kwepamusoro, makemikari ekuyera haangogone kubatsira kupenda kuti kuenzane chete, asiwo zvinogona kukonzera migumisiro yakaipa. Panguva yekushandiswa, chinonyanya kufungwa nezvacho mhedzisiro yakaipa yemakemikari ekuyera pakugadzirisazve uye kudzivirira kuputika kwe cratering ye jira, uye kuenderana kwemakemikari ekuyera akasarudzwa kunofanirwa kuyedzwa kuburikidza nekuyedza.

1. Mushonga wekuyera solvent wakasanganiswa

Inoumbwa nezvinhu zvinonyungudutsa zvine aromatic hydrocarbon zvine mwero wekufashaira, ma ketone, ma esters kana zvinonyungudutsa zvakanaka zvemapoka akasiyana-siyana anoshanda, uye musanganiswa wezvinonyungudutsa zvine mwero wekufashaira. Pakugadzirira nekushandisa, kutarisisa kunofanira kupihwa kune mwero wayo wekufashaira, mwero wekufashaira uye kunyungudika, kuitira kuti chifukidziro chive nemwero wekushaira uye kunyungudika kwe solvent panguva yekuomesa. Kana mwero wekufashaira wakaderera zvakanyanya, ucharamba uri mufirimu rependi kwenguva yakareba uye haugone kuburitswa, izvo zvinokanganisa kuoma kwefirimu rependi.

Rudzi urwu rwemushonga wekuyera runokodzera chete kugadzirisa zvikanganiso zvekuyera (sekuderera, kuchena, uye kupenya kusina kunaka) zvinokonzerwa nekuoma nekukurumidza kwemushonga wekuyera uye kusanyunguduka kwechinhu chepasi. Chiyero chinowanzova 2% ~ 7% yependi yese. Izvi zvinozowedzera nguva yekuoma kwependi. Kune machira ekuomesa tembiricha yemumba (senge pendi ye nitro) anowanzo kudonha kana akaiswa pafacade, haangobatsiri chete nekuyera, asiwo anobatsira kuvandudza kupenya. Munguva yekuomesa, inogona zvakare kudzivirira mabubble emushonga wekuyera uye maburi emapini anokonzerwa nekubuda kwemushonga nekukurumidza. Kunyanya kana ikashandiswa mumamiriro ekunze ekupisa kwakanyanya uye hunyoro hwakawanda, inogona kudzivirira pamusoro pefirimu rependi kuti isaome nguva isati yakwana, kupa curve yakafanana yekuora kwemushonga wekuyera, uye kudzivirira kuitika kwemhute chena mupendi ye nitro. Rudzi urwu rwemushonga wekuyera runowanzo shandiswa pamwe chete nezvimwe zvinoyera.

2. Zvishandiso zveAcrylic leveling

Rudzi urwu rwekuyera simbi rinowanzova copolymer ye acrylic esters. Hunhu hwayo ndehwekuti:

(1) Alkyl ester ye acrylic acid inopa basa guru pamusoro;

(2) Yayo−COOH,−OH, uye−NR inogona kubatsira kugadzirisa kuenderana kwechimiro chealkyl ester;

(3) Huremu hwemamorekuru hunoenderana zvakananga nekushanda kwekupedzisira kwekupararira. Kuenderana kwakakosha uye kurongeka kwecheni yepolyacrylate zvinhu zvinodiwa kuti ive mumiriri akakodzera wekuyera. Maitiro ayo ekuyera anogona kuoneka zvakanyanya padanho rekupedzisira;

(4) Inoratidza hunhu hwekudzivirira furo uye kusvibisa matumbu mumasisitimu akawanda;

(5) Chero bedzi paine mapoka mashoma anoshanda (akadai se--OH, -COOH) muchikamu chekuyera, kukanganisa pakudzoreredza hakuonekwe, asi pachine mukana wekuti kudzoreredza kudzoreredza;

(6) Kunewo dambudziko rekufananidza polarity uye compatibility, izvo zvinodawo kusarudzwa kwekuyedza.

3. Mushonga wekuyera silicone

MaSilicone imhando yepolymer ine cheni yesilicon-oxygen bond (Si-O-Si) semaskeleton nemapoka eorganic akabatana nemaatomu esilicon. Mazhinji emasilicone compounds ane cheni dzemativi dzine simba shoma repamusoro, saka mamorekuru esilicone ane simba shoma repamusoro uye kushushikana kwepamusoro kwakaderera.

Chinhu chinonyanya kushandiswa chepolysiloxane ipolydimethylsiloxane, inozivikanwawo se methyl silicone oil. Kushandiswa kwayo kukuru ndekwe defoamer. Mhando dzisina huremu hwemamorekuru dzinoshanda zvakanyanya mukusimudzira kuenzana, asi nekuda kwezvinetso zvakakomba zvekuenderana, dzinowanzo tetepa kana kutadza kudzoreredza. Saka, polydimethylsiloxane inofanira kuchinjwa isati yashandiswa zvakachengeteka uye zvinobudirira mukupfekedza.

Nzira huru dzekugadzirisa ndeidzi: polyether modified silicone, alkyl nedzimwe side group modified silicone, polyester modified silicone, polyacrylate modified silicone, fluorine modified silicone. Kune nzira dzakawanda dzekugadzirisa polydimethylsiloxane, asi dzese dzakagadzirirwa kuvandudza kuenderana kwayo ne coatings.

Rudzi urwu rwemushonga wekuyera runowanzova nemigumisiro yekuyera uye yekusvibisa. Kuenderana kwaro nependi kunofanira kuonekwa kuburikidza nemiedzo usati washandisa.

4. Pfungwa huru dzekushandisa

Sarudza mhando chaiyo: Sarudza chinhu chakakodzera chekuyera zvichienderana nerudzi uye zvinodiwa zvechipfeko. Pakusarudza chinhu chinoyera, kuumbwa kwacho uye hunhu hwacho pamwe chete nekuenderana kwacho nechipfeko chacho pachacho zvinofanirwa kutariswa; panguva imwe chete, zvinhu zvakasiyana-siyana zvekuyera kana zvimwe zvinowedzera zvinowanzo shandiswa pamwe chete kuti zvinhu zvakasiyana-siyana zvienzaniswe.

Teerera huwandu hwakawedzerwa: kuwedzera kwakanyanya kunokonzera matambudziko akadai sekuoma uye kudonha pamusoro pechifukidziro, nepo kuwedzera kushoma kusingazokwanisi kuita kuti chifukidziro chienzane. Kazhinji, huwandu hwakawedzerwa hunofanira kutariswa zvichienderana nekusimba uye zvinodiwa zvechifukidziro, kutevedzera mirairo yekushandisa reagent, uye kusanganisa mhedzisiro chaiyo yebvunzo.

Nzira yekuputira: Kushanda kwekuisa mazinga ejira kunokanganiswa nenzira yekuputira. Paunenge uchishandisa chinhu chinokwidza mazinga, unogona kushandisa brushing, roller coating kana spraying kuti basa rechinhu chinokwidza mazinga rive rakazara.

Kukurunga: Pakushandisa chinhu chinoyera, pendi inofanira kukurunga zvizere kuitira kuti chinhu chinoyera chipararire zvakaenzana mupendi. Nguva yekukurunga inofanira kusarudzwa zvichienderana nehunhu hwechinhu chinoyera, kazhinji isingapfuure maminetsi gumi.
