Mapurasitiki ePolurea anonyanya kuumbwa nezvinhu zveisocyanate uye mapolyether amines. Zvinhu zviripo pari zvino zvepolyurea zvinosanganisira MDI, polyether polyols, polyether polyamines, amine chain extenders, zvimwe zvinhu zvinoshanda, pigments uye fillers, uye active diluents. Mapurasitiki ePolurea ane hunhu hwekumhanya nekukurumidza, kukurumidza kuvaka, kudzivirira ngura uye kushanda kwemvura, kupisa kwakakura, uye maitiro ari nyore. Anonyanya kukodzera maindasitiri akasiyana-siyana uye migodhi, nzvimbo dzekupaka mota, nzvimbo dzemitambo, nezvimwewo, zvepurasitiki pasi zvine zvinodiwa zvekudzivirira kutsvedza, kudzivirira ngura uye kusakara.

ZVINHU ZVECHIGADZIRWA

Kuramba kupfeka kwakanyanya, haikwenyi, uye hupenyu hwebasa hwakareba;
Iine kusimba kuri nani pane epoxy flooring, isina kukwenya kana kutsemuka:
Kukweshana kwepamusoro kwakanyanya, zvichiita kuti isatsvedze kupfuura epoxy flooring.
Kugadzirwa kwefirimu rejasi rimwe chete, kuoma nekukurumidza, kuvaka kuri nyore uye nekukurumidza:
Kupenda patsva kunonamira zvakanaka uye kuri nyore kugadzirisa.
Mavara anogona kusarudzwa zvakasununguka. Akanaka uye anopenya. Haana chepfu uye haakuvadzi nharaunda.

Maitiro ekuvaka

Chigadziko Chemitambo

1. Kugadzirisa pamusoro pechinhu: Bvisa guruva, mavara emafuta, munyu, ngura, uye zvinhu zvinoburitsa zvinhu kubva pasi pechinhu nekutanga nekutsvaira wozochenesa. Mushure mekukuya zvakanaka, guruva rinounganidzwa.
2. Kushandisa primer yakakosha: Peta primer yakakosha yepolyurea kuti uvhare ma capillary pores, kuderedza zvikanganiso zvekufukidza, uye kuwedzera kunamira pakati pe polyurea coating ne base surface.
3. Kugadzira ne polyurea putty (zvichienderana nemamiriro ekupfekwa kwepasi): Shandisa zvinhu zvakakosha zvekugadzira polyurea kugadzirisa uye kuenzana kwepasi. Mushure mekugadzika, shandisa vhiri rekukuya remagetsi kuti uchenese zvakanaka wobva washandisa vacuum cleaner kuchenesa.
4. Peta shandisa primer yakakosha yepolyurea: Vharazve pamusoro pevhu, zvichiwedzera zvakanyanya kunamira pakati pepolyurea nehwaro.
5. Pfapfaidza polyurea isingapindi mvura: Mushure mekuedza spray, pfapfaidza nenzira kubva kumusoro kusvika pasi wozobva waisa pasi, uchifamba munzvimbo diki nenzira yakachinjika uye yakareba. Ukobvu hwependi yacho i1.5-2mm. Kupfapfaidza kunoitwa kamwe chete. Nzira dzakananga dzinogona kuwanikwa mu "Polyurea Engineering Coating Specifications". Inoita basa guru mukudzivirira mvura, haipfeki uye haitsvedzi.
6. Pfapfaidza/purura isa topcoat yakakosha yepolyurea: Sanganisa chinhu chikuru chinorapa nechinhu chinorapa zvakaenzana, kurunga zvakanaka, uye shandisa special roller kupuruzira zvakaenzana polyurea topcoat coat pamusoro pepolyurea coat yakaporeswa zvachose. Inodzivirira mwaranzi ye ultraviolet, inodzivirira kukwegura uye kuchinja kweruvara.

Uriri hweworkshop

1. Kugadzirisa nheyo: Kurura jira rinoyangarara panheyo, uchiisa pachena nzvimbo yakaoma yenheyo. Iva nechokwadi chekuti nheyo yasvika pagiredhi reC25 kana kupfuura, yakati sandara uye yakaoma, haina guruva, uye haidzokeri jecha zvakare. Kana paine huchi, nzvimbo dzisina kurongeka, mitswe, nezvimwewo, shandisa zvinhu zvekugadzirisa kugadzirisa uye kuienzanisa kuti ive nechokwadi chekuti inogara kwenguva refu.
2. Kuisa pombi yepolyurea: Isa pombi yepolyurea special primer zvakaenzana pahwaro kuti uvhare ma capillary pores pamusoro, simbisa chimiro chevhu, kuderedza zvikanganiso mu coating mushure mekupfapfaidza, uye kuwedzera kunamira pakati pe polyurea putty nesimende, pasi rekongiri. Mirira kusvika yanyatsopora usati waenderera mberi nedanho rinotevera rekuvaka. Kana paine nzvimbo yakakura yeruvara ruchena mushure mekuisa, inofanira kuiswazve kusvika pasi rese raita brown yakasviba.
3. Kuisa Polyurea putty: Isa polyurea special putty inoenderana zvakaenzana pahwaro kuti pasi pave pakadzikama, vhara ma capillary pores asingaonekwe nemaziso, uye dzivisa mamiriro ezvinhu apo kupfapfaidza polyurea kunokonzera maburi madiki nekuda kwema capillary pores ari pasi. Mirira kusvika yapora zvizere usati waenderera mberi nedanho rinotevera rekuvaka.
4. Kuisa polyurea primer: Pa polyurea putty yapora, isa polyurea primer zvakaenzana kuti uwedzere kubatana pakati pe polyurea layer yakapfapfaidzwa ne polyurea putty.
5. Kugadzira polyurea: Mukati memaawa makumi maviri nemana mushure mekupora kweprimer, shandisa michina yekupfapfaidza yehunyanzvi kuti ufafadze polyurea zvakaenzana. Pamusoro pejira rinofanira kunge rakatsetseka, pasina mvura inoyerera, maburi, maburi, kana kutsemuka; kana paine kukuvara kwenzvimbo kana maburi, kugadzirisa polyurea nemaoko kunogona kushandiswa.
6. Kushandiswa kwePolyurea topcoat: Kana pamusoro pepolyurea paoma, isa polyurea topcoat kudzivirira kukwegura, kuchinja ruvara, uye kuwedzera kuramba kwekupfekwa kwepolyurea coat, zvichidzivirira polyurea coat.

Midziyo yekuchera

1. Substrate yesimbi, jecha rinoputika kuti ribvise ngura rinosvika pachiyero cheSA2.5. Pamusoro payo hapana guruva rekusvibiswa, mavara emafuta, nezvimwewo. Kurapa kwakasiyana kunoitwa zvichienderana nehwaro.
2. Kupfapfaidza ne primer (kuwedzera kunamira kwe polyurea kuhwaro).
3. Kuvakwa kwepurasitiki inopfapfaidza (chikamu chikuru chinodzivirira. Ukobvu hwacho hunowanzo kurudzirwa kuva pakati pe2mm ne5mm. Mapurani chaiwo ekuvaka anopiwa zvichienderana nezvigadzirwa zvinoenderana).
4. Kuvakwa kwebrashi/spraying pamusoro pejasi (kunodzivirira yero, kuramba UV, kuwedzera mhando dzakasiyana dzemavara).
