Thermoplastic Powder yeDipping Zvinangwa
Kutanga kwe thermoplastic poda yekunyudza zvinangwa
Upfu hwethermoplastic hwekushandisa pakunyikwa imhando yezvinhu zvinofukidza upfu zvinoshandiswa kupa chifukidziro chinodzivirira uye chinoshongedza zvinhu zvakasiyana-siyana. Chifukidziro chinoiswa kuburikidza nekunyikwa, uko chinhu chinonyikwa mumudziyo wakazadzwa neupfu hwethermoplastic. Zvidimbu zveupfu zvinonamatira pamusoro pechinhu, zvichiita chifukidziro chakafanana uye chinoenderera mberi.
Iyo thermoplastic poda inowanzogadzirwa kubva mupolymer resin, iyo inogona kunyungudutswa uye kusimbiswa zvakare kakawanda pasina kuchinja kwakakosha kemikari. Chimiro ichi chinoita kuti hupfu hupiswe uye hunyunguduke pamusoro pechinhu panguva yekunyura. Kana yatonhodzwa, hupfu hunoumba chifukidzo chakasimba uye chinodzivirira.
Dipping Process
Iyo thermoplastic poda dipping process inosanganisira akati wandei matanho. Kutanga, chinhu chacho chinocheneswa uye chisati chagadziriswa kuti chibvise chero tsvina, mafuta, kana zvimwe zvinosvibisa zvinogona kukanganisa kunamatira kwehupfu. Iko kusati kwarapwa kunogona kusanganisira kuwacha, kubvisa mafuta, kana kuputika kwejecha, zvichienderana nerudzi rwechinhu uye chishuwo chekupfekedza.
Zvadaro, chinhu chinodziiswa kusvika patembiricha yakatarwa, kazhinji pakati pe250°C ne330°C, kuitira kuti pamusoro pacho paome uye pasave nehunyoro. Chinhu chacho chinozonyudzwa mumudziyo wakazadzwa neupfu hwethermoplastic. Mudziyo wacho mubhedha une mvura.
Mumubhedha wakanyoroveswa, zvimedu zvehupfu zvinomiswa mumhepo, zvichiita mubhedha wakafanana nemvura. Chinhu chacho chinonyudzwa mumubhedha, uye zvimedu zvehupfu zvinonamatira kumusoro nekuda kwekuita kwemvura.
Mushure mokunge chinhu chacho chabviswa mumudziyo wehupfu, hupfu hwakawandisa hunowanzobviswa kuburikidza nekudengenyeka kana kuvhuvhuta kwemhepo. Chinhu chakaputirwa chinobva chaiswa pakurapa, uko kunosanganisira kudziyisa chinhu chacho kusvika kune imwe tembiricha kwenguva yakati. Munguva iyi, iyo thermoplastic poda inonyunguduka uye inoyerera, ichigadzira inoenderera uye yakafanana coating. Kana yatonhodzwa, kupeta kunoomesa uye kunopa dziviriro yakanakisa kubva pakupfeka, makemikari, uye mwaranzi yeUV.
Advantages
Thermoplastic poda coatings inopa akati wandei mabhenefiti pamusoro pedzimwe nzira dzekupfeka. Ivo vane yakaderera nharaunda kukanganisa sezvo ivo vasina volatile organic compounds (VOCs) uye inogona kugadzirwa zvakare nyore. Ivo zvakare vanopa huwandu hwakasiyana hwemavara, huchibvumira kugadzirisa uye aesthetic kukwezva.
Muchidimbu, thermoplastic poda yezvinangwa yekunyudza ndeye inochinja-chinja uye yakasimba yekubatisa zvinhu zvinogona kuiswa kuburikidza nekunyudza. Iyo inopa yakanakisa adhesion, kusimba, uye corrosion resistance zvivakwa, zvichiita kuti ive yakakodzera kune akasiyana maindasitiri. Kudhibha kunosanganisira matanho akati wandei, anosanganisira pre-kurapwa, kudziyisa, kunyudza, uye kurapa. Thermoplastic poda coatings inopa akati wandei mabhenefiti pamusoro pedzimwe nzira dzekupfekedza, kusanganisira kuderera kwemamiriro ekunze uye sarudzo dzekugadzirisa.
