  1. Siv 120-grit sandpaper kom ntxhib ntawm qhov chaw HDPE .
  2. Siv lub khw-vac nrog lub bristle txuas los tshem tawm HDPE hmoov av.
  3. Sib tov kua nplaum raws li cov neeg tsim khoom cov lus qhia.
  4. Thov lub kua nplaum thickly rau saum npoo ntawm lub HDPE .
  5. Nias lub glued HDPE mus rau qhov chaw uas koj xav muab nws.

Tsis tas li ntawd, cov kua nplaum ua haujlwm dab tsi ntawm HDPE?

HDPE GLU . Pro-Poly yog lub zog siab polyethylene nplaum rau kev sib txuas ntawm HDPE yeeb nkab siv cov txheej txheem PVC couplings, HDPE couplings thiab lwm yam ntaub ntawv uas tsis yog-standard. Pro-Poly kuj tseem siv rau kev sib txuas polypropylene, LDPE, ABS, polycarbonate, nylon, fiberglass, hlau thiab txhuas.

Tom qab, lo lus nug yog, dab tsi yuav lo rau polyethylene? Lub Loctite All-Plastic Super Glue suav nrog lub raj ntawm kev sib txuas tus neeg sawv cev thiab lub raj mis ntawm qhov chaw ua haujlwm. Nws bonds nrog tawv thiab mos yas. Cov kua nplaum ua haujlwm zoo nrog polyethylene thiab polypropylene nto.

Hais txog qhov no, silicone puas yuav lo rau HDPE?

Polypropylene thiab polyethylene hu ua "low energy" lossis "non- stick " plastics. Cov pab pawg no suav nrog Teflon (los yog polytetrafluoroethylene). Cyanoacrylate, epoxy, polyurethane, silicone (RTV piv txwv), thiab feem ntau acrylic nplaum tsis stick rau polypropylene thiab polyethylene.

Yuav ua li cas muab HDPE rau hlau?

Txhawm rau muab cov nplaum polyethylene rau hlau

  1. Rough ob lub polyethylene thiab hlau nto nrog ib tug tsawg grit xuab zeb ntawv.
  2. Saturate lub polyethylene nrog ib tug adhesion txhawb tsim los ua hauj lwm nrog pol-plastics.
  3. Txau cov kuab tshuaj raws li Activator / Accelerator rau ntawm polyethylene nto los yog hlau.
