Chii chinonzi pu yeganda risina solvent?

Solvent-isina PU dehwe iganda rekugadzira rine hushamwari rinoderedza kana kudzivirira zvachose kushandiswa kweorganic solvents mukugadzira kwayo. Traditional PU (polyurethane) maitiro ekugadzira matehwe anowanzo shandisa organic solvents se diluents kana additives, izvo zvingave zvisina kunaka kwezvakatipoteredza uye hutano mhedzisiro. Kuti uderedze kuita uku, dehwe rePU-isina solvent rinoshandisa nzira dzakasiyana dzekugadzira, senge tekinoroji yemvura kana mamwe matekinoroji ane hushamwari, kutsiva echinyakare organic solvents.

Saka sei solvent-isina PU dehwe rinogadzirwa?
Ngatitangei titarise kuti inogadzirwa sei-isina PU dehwe:
1. Kugadzirira kwejira rekutanga: Kutanga, unoda kugadzirira jira rekutanga, iro rinogona kuva donje kana zvimwe zvinhu zvakagadzirwa. Iyi substrate ichave hwaro hwePU dehwe,
2. Coating primer: Isa chigadziko cheprimer pamucheka wepasi. Iyi substrate inowanzova polyurethane (PU), iyo ine yakanaka adhesion properties uye kupfeka kuramba.
3. Kupfekedza chikamu chepamusoro: Mushure mokunge primer yakaoma, shandisa chidimbu cherudo. Iyi dhizaini zvakare yakagadzirwa ne polyurethane, iyo inotaridza kutaridzika uye kunzwa kwePU dehwe. Zvimwe zvikamu zvepamusoro zvingada kurapwa kwakakosha, sekunge embossing, kudhinda kana kutevedzera ganda rematehwe, kuwedzera kugadzirwa uye kunaka kweganda.
4. Kuomesa uye kuporesa: Mushure mekupedza jira rezhizha, PU yeganda inotumirwa kukamuri yekuomeswa kana kuburikidza nedzimwe nzira dzekuporesa, kuitira kuti primer uye nzvimbo yepamusoro inoporeswa zvakakwana uye yakabatanidzwa.
5. Kupedzisa nekucheka: Mushure mokunge PU yeganda yakagadziriswa, nzira yekupedzisa inoda kuitwa, kusanganisira kucheka muchimiro chaidiwa uye ukuru kuitira kuti uite zvigadzirwa zvekupedzisira zveganda, zvakadai sehombodo, shangu, nezvimwewo. Aya machira haabudise organic zvinonyungudutsa kana kuburitsa zvidiki zvidiki zvezvinonyungudutsa panguva yekupfeka, nekudaro kuderedza kusvibiswa kwezvakatipoteredza uye kukanganisa hutano hwevashandi.

Sei dehwe risina solvent-free pu richinyanya kufarirwa iye zvino?
Tese tine dambudziko here, patinoenda kuzvitoro kunotenga sofa kana fenicha, toona yakanaka uye ine fashoni chena sofa yeganda kana fenicha yematehwe, tinoda kutenga, asi zvakare kunetseka nezve chena sofa yeganda haina kusvibiswa netsvina, haipindike, isiri nyore kuchenesa, saka nguva zhinji unokanda mapfumo pasi nekuda kwechikonzero ichi, ikozvino usazvidya moyo, isu hatina dambudziko rekunyungudutsa. Solvo-yemahara PU dehwe nekuchengetedzwa kwayo kwezvakatipoteredza, kuita kwepamusoro uye maitiro akawanda ekushanda, asi zvakare ine hunhu hwekuramba tsvina, kuramba kukwenya uye kuchenesa kuri nyore, saka tinogona kusarudza iyo solvo-yemahara PU dehwe rakagadzirwa nesofa chena, hatichanetseke nezvesofa chena harina kusvibiswa, hatichanetseki nezvevana vane misikanzwa vachidhirowa pasofa nepeni.
Solvent-isina PU dehwe rinosangana nezvinodiwa zviviri zvevatengi vemazuva ano uye vagadziri vemhando yechigadzirwa uye mutoro wezvakatipoteredza, izvo zvinoita kuti ive ine hushamwari nharaunda uye inogadzikana sarudzo uye nekudaro inowedzera kufarirwa mumusika.
