Thermoplastic Powder Coatings Types

Thermoplastic poda coatings mhando kunyanya vane marudzi anotevera:

• Polypropylene
• Polyvinyl chloride (PVC)
• Polyamide (zvinhu zvenaironi)
• Polyethylene (PE)

Mabhenefiti akanaka emakemikari kuramba, kusimba uye kuchinjika, uye anogona kuiswa kune akakora machira. Izvo zvisingabatsiri kupenya kwakashata, kusaenzana kwakanaka uye kusanamatira zvakanaka.

Iyo chaiyo sumo ye thermoplastic poda yekuputira marudzi:

Polypropylene powder coating

Polypropylene poda coating ndeye thermoplastic chena poda ine chidimbu dhayamita ye50 ~ 60 mesh. Inogona kushandiswa mu-anti-corrosion, kupenda uye mamwe minda.

Iyo thermoplastic coating yakagadzirwa nepolypropylene seye matrix resin uye yakagadziridzwa nekugadziriswa kwemuviri nemakemikari. Iine anotevera maitiro ekuita: yakanakisa kusamira kwemamiriro ekunze, kemikari kusagadzikana kwecorrosion, uye yakanyanya kunamatira kusimbi (senge simbi) substrates. Nzira yekushandisa: mubhedha wakanyungudika, electrostatic spray uye flame spray. Iyo yekuputira pamusoro yakati sandara, ukobvu hwakafanana uye hunogona kugadziriswa zvisina tsarukano.

Polyvinyl Chloride (PVC) Powder Coating

Polyvinyl chloride (PVC) poda coating ine zvakawanda zvakasiyana ruvara masisitimu, yakanaka yemamiriro ekunze kuramba, yakanakisa corrosion kuramba kweiyo bhaisikopo rekuputira, kuramba doro, peturu, uye anonhuwirira hydrocarbon zvinonyungudutsa, yakakwirira mechanical simba, uye kuchinjika kunoshamisa. Iyo yepamusoro-soro yekudzivirira ndeye (4.0-4.4) × 10 4 V / mm, iyo firimu yekuputira inotsvedza, inopenya uye yakanaka, uye mutengo wakaderera.

Iyo polyvinyl chloride poda yehupfu inogona kunyikwa mumubhedha wakanyungudutswa, uye saizi yehupfu yehupfu inodiwa kuve 100μm-200μm; kana electrostatic poda coating, saizi yehupfu yehupfu inodiwa kuve 50μm-100μm.

Polyamide (Nylon) Powder Coating

Polyamide resin, inowanzo zivikanwa senaironi, iresi ye thermoplastic ine zvakawanda zvekushandisa. Polyamide resin ine yakanaka yakazara zvivakwa, yakanyanya kuomarara, kunyanya yakasarudzika kupfeka kuramba. Firimu rayo rekuputira rine diki static uye dynamic friction coefficients, ine lubricating kugona, uye ine yakaderera kumhanya ruzha panguva yekushanda. Iro jira rakanakira kusapfeka risiri rakarukwa. Mafuta ekuzora ane yakanaka kuchinjika uye yakanakisa adhesion, makemikari kuramba, solvent kuramba, inoshandiswa kupfekedza machira emuchina mabhengi, magiya, mavharuvhu, midziyo yemakemikari, midziyo yeutsi, nezvimwe.

Polyethylene Powder Coating

Polyethylene poda coating is anti-corrosion powder coating inogadzirwa ne-high-pressure polyethylene (LDPE) sechinhu chekutanga, ichiwedzera zvakasiyana-siyana zvekuwedzera zvinoshanda uye kugadzirira kwemavara. Iyo yekuputira layer ine yakanakisa makemikari kuramba, kuchembera kuramba, kukanganisa kupikisa uye kukotama kuramba. , acid kuramba, munyu pfapfaidzo corrosion resistance, uye ine yakanaka yekushongedza pamusoro pekuita.
