Mazuva ano, vanhu vanoteerera kune yakaderera kabhoni uye kuchengetedzwa kwezvakatipoteredza, saka kana vachishongedza, vanhu vazhinji vachasarudza zvimwe zvinoshamisa zvematongerwo enyika. Nhasi isu tinonyanya kutaura nezve zvakatipoteredza hushamwari mvura yemvura. Mvura yemvura inonyanya kukamurwa kuita marudzi maviri ezvipfuyo: marara emvura Saka chii musiyano uripo pakati peiyi maviri maviri emvura emvura?

Musiyano uripo pakati pejasi-yakavakirwa mvura uye mongororo-yakavakirwa mapepa anogona kutaurwa kubva kune zvinotevera maonero:

A. Misiyano mumatare ekubatanidza

1. Iyo resin yakasiyana. Iyo resin yemvura-yakavakirwa pendi ndeyekunyaradza mvura uye inogona kuparadzirwa (yakanyungudutswa) mumvura;

2. Iyo duliuent (solvent) yakasiyana. Pendi-dzakavakirwa pamvura dzinogona kuderedzwa ne digater (Dioned mvura) mune chero chikamu, chakavakirwa-pendi dzinogona kungoiswa pamwe chete nemafuta ekunyora (kusanzwisisika pervente, chena chena mafuta, nezvimwewo).

B. Yakasiyana Kubatanidza Kuvaka Zvinodiwa

1. Kune iyo nzvimbo yekuvaka, iyo nzvimbo yekuvhara ndeye 0 ° C, saka machira emvura haagoni kuiswa pazasi 5 ° C, nepo magetsi ekurongedza anogona kuiswa pamusoro -5 pasi uye kupindirana pakati pematai kuchaderedzwa;

2. Zvekuita visikoka Kubata simba rekuvhara kwependi, uye kuwedzera huwandu hwekuvaka kupfuura), Solvent-based gadziriso yekugadzirisa iri nyore, uye muganho weViscosity zvichakanganisawo sarudzo yekuvaka;

3. Kuti uise kuporesa uye kupora, iyo pendi yakavakirwa mvura yakakwira uye iyo yakakwira uye tembiricha yakaderera, iyo nguva yekuomesa yakawedzerwa, asi kana tembiricha yakacheneswa, iyo mvura-yakavakirwa mvura Pendi zvakare inodawo kupiswa mune gradient, uye ichapinda yakakwira nharaunda pakarepo. Mushure mekunge pendi-yakavakirwa pendi yekuputirwa kwemvura yemukati yemukati inogona kukonzeresa mapini kana kunyange yakakura-chiyero bubbling, nekuti mvura chete inoshandiswa pendi yemvura, uye hapana kufinha gradient gradient. Zvemari solvent-yakavakirwa, iyo duliuent yakaumbwa ne organic soles ine akasiyana mapoinzi ekubira, uye pane akawanda kulatilization gradient. Zvakafanana zviitiko hazvizoitika mushure mekupenya (nguva yekuomesa mushure mekunge kuvakwa kwapera kune iyo nguva yekuomesa usati wapinda oveni).

C. Misiyano mukubatanidza kushongedza mushure mekuumbwa kwemafirimu

C-1. Kutaura kwakasiyana-siyana

1. Solvent-based coatings inogona kudzora iyo yakajeka yeiyo pigment uye mafirita zvichienderana nekukuya, uye hazvisi nyore kutinhira panguva yekuchengetedza. Nekuwedzera resins kudzora iyo yekuvhara PVC (pigment-to-base ratio), yakadai seyakagadziriswa mulks yefirimu, iyo gloss inogona kunge iri matte, matte, hafu-matte, uye yakakwira- gloss. Iyo gloss yemotokari pendi inogona kuve yakakwira se 90% kana anopfuura;

2. Kutaura kwakawanda kwemapendi emvura-yakavakirwa mvura seyakaipisisa pendi yemafuta-yakavakirwa, uye kutaura kwepamoyo kwakakwirira kune murombo. Izvi imhaka yekuti mvura iri mumvura-yakavakirwa mvura pendi inoshandiswa sediki. Hunhu hwekuvhara hwemvura hunoita kuti zviome kune mapepa emvura-akavakirwa pamvura

Ratidza zvinopfuura 85% yakakwira gloss. .

C-2. Kutaura kwakasiyana kwemavara

1. Solvent-based Coatings ine huwandu hwakawanda hwemifananidzo uye mafirita, organic kana organic, saka mavara akasiyana-siyana anogona kugadziriswa, uye kutaura kwemavara kwakanaka;

2. Iko kusarudzwa kwakasiyana kwemifananidzo uye mafirita emvura-yakavakirwa mvura pendi idiki, uye zvizhinji zveganda hazvigone kushandiswa. Nekuda kweiyo isina kukwana mavara, zvakaoma kugadzirisa mavara akapfuma senge solvent-based pendi.

D. Kuchengetedza uye kufambisa

Pendi-yakavakirwa mapepa haina inopisa organic sol sol, uye yakachengeteka kuchengeta uye kutakura. Kana iri yekusvibiswa, vanogona kushambidzwa uye vakanyorerwa nemvura yakakura. Nekudaro, kupururirwa kwemvura kwemvura kune tembiricha zvinodiwa zvekuchengetedza uye zvekufambisa. Mukaka uye zvimwe zvakaipa.

E. Inoshanda kutapurirana

Solvent-based Coatings inonyanya kugadzirwa zvigadzirwa, uye zvigadzirwa zvemagetsi zvichave nematambudziko akateedzana senge chiratidzo uye carbonization pasi pemamiriro ekunze akanyanya. Parizvino, iyo yakanyanya kupisa kurwisa zvigadzirwa zve organic haina kupfuura 400 ° c.

Yakasarudzika yakanyanya-tembiricha yekudzivirira ichishandisa yakasarudzika inorganic resins mumakosi emvura-yakavakirwa mvura inogona kutsungirira kupisa kwezviuru zvemadhigiri. Semuenzaniso, zs Series-tembiricha-inodzivirira mvura-yakavakirwa manhamba ekushambadzira hazvigoneke kuti solvent-based coatings.

G. Misiyano mukuchengetedza uye kuchengetedza zvakatipoteredza

Solvent-based Coatings ine angangoita mazano ekuchengetedza emoto uye kuputika panguva yekugadzira, kufambisa, kuchengetedza, uye kushandiswa. Kunyanya munzvimbo dzakavharidzirwa, ivo vanokwanisa kukonzeresa kuputika uye kuputika. Panguva imwecheteyo, organic sol moventats yacho zvakare inokonzeresa zvimwe kukuvara kumuviri wemunhu. Mhosva yakakurumbira ndiyo nyaya yeToluene ichikonzera cancer, uye tluene haisisiri kubvumidzwa kushandiswa. Vheni yeVO Solvent-yakavakirwa, uye zvigadzirwa zvakajairika ndezvekuwedzera seanopfuura 400. Mabhizinesi ari pasi pekudzvinyirirwa zvakanyanya pakudzivirira kwemamiriro ekunze uye kuchengeteka kana achishandisa solvent-based coatings.

Zvinyorwa zvemvura-zvakavakirwa zvine hushamwari uye zvakachengeteka mukugadzirwa, zvekufambisa, kuchengetedza, uye kunze kwezvinhu zvemvura-zvemvura-kubva kune vamwe vagadziri vasina kurongeka).

Mhedziso:

Mavara-akavakwikewa majasi uye solvent-based coatings ane yavo zvakanakira uye zvakashata. Nekuti kutsvagurudza kwemvura-yakavakirwa mvura kuchiri kusimba kwemvura kuchiri kuita, kuita kwemvura-yakavakirwa mvura hakugone kuzadzisa zvido zvekugadzira munharaunda. Iko kushandiswa kweiyo solvent-based tourings ichiri kudikanwa. Mamiriro chaiwo chaiwo anoongororwa uye akatongwa, uye haagoni kurambwa nekuda kwechimwe chinhu chisina kunaka cherudzi rweimwe pendi. Zvinotendwa kuti nekudzvinyirira kwekutsvagurudza kwesainzi pane zvevatengi zvemvura, rimwe zuva, zvakasarudzika zvine hushamwari uye zvipfeko zvitsva zvakachengeteka zvichashandiswa zvakanyanya mukona imwe neimwe yepasi.
