1、Makomba anopupuma asina kukwana

Zvinokonzera:

(1) matambudziko emhando yeanopupa furo;

(2) purasitiki yakaderera yezvinhu zverabha;

(3) yakanyanya kusanganiswa tembiricha uye kutanga kuora kweanopupa agent;

(4) Rabha yakapakwa kwenguva yakareba kana kuti yakanyanya tembiricha, uye imwe yeanopupa inobuda kana kuora;

(5) Iyo vulcanization kumhanya yerabha inokurumidza;

(6) dzvinyiriro yacho yakanyanyisa, inopfuura dzvinyiriro yemukati inoumbwa negasi remushonga unopupa, zvichikonzera kusakwana kwemakomba anopupuma;

Countermeasures:

(1) tarisa kana mumiriri anopupa ari mukati menguva shoma uye kuti anokodzera here;

(2) tarisa kana plastiki yezvigadzirwa zverabha inosangana neyakajairwa, purasitiki yakaderera zvakanyanya inofanira kuwedzerwa nekusanganisa, kuwedzera plasticity kuti ifambise kukura kwemakomba;

(3) Tarisa uone kana tembiricha yekuyerera yemuchina wekusanganisa yakakwira zvakanyanya, kana tembiricha yeroll yakanyanyisa, uye kuti rabha rapiswa here. Zvimwe zvinhu zverabha zvine tembiricha yekusanganisa yakakwira zvinogona kusanganiswa nehuwandu hushoma hwekurapa kana kuwedzera furo agent inorema indasitiri;

(4) Rabha rinofanira kudzoserwa pakucheneswa kuti riwedzere kugadziriswa mushure menguva yakarebesa yokupaka;

(5) gadziriso yeformula, tarisa kana tembiricha yakakosha yeajenti inokuvadza uye tembiricha yekuparara yeanopupa ari padyo nemumwe, uye kurongeka pamwe chete kuita kuti vulcanization imhanye nekumhanya kwefuro kuenderana;

(6) gadzirisa kudzvinyirira kwemuchina.

2. Kusakwana kuzadza mold

Zvinokonzera:

(1) Kusakwana kwerabha inoshandiswa;

(2) Kusakwana mold kupera kana mold inoshandiswa kwenguva yakareba pasina kuchenesa, kuyerera kwerabha kunoenderana nekupikiswa;

(3) Chimiro chegomba chakaoma uye kuyerera kwerabha hakuenderane, uye kazhinji haigone kuzadza pamusoro pe mold mushure mekunge gomba raburitswa, richigadzira kukanganisa;

(4) Mhepo iri mukona yakafa ye mold cavity haigoni kubudiswa, kuitira kuti rubber isazadzwa negomba, zvichiita kuti kumucheto kwekushaya glue;

Countermeasures:

(1) Kuyera huremu hwehuremu hwenamo;

(2) kunatsiridza kuyerera kwerabha;

(3) Shandura mold, inonzwisisika dhizaini yemakomba emhepo ekufambisa, mold chimiro, nezvimwe.

3. Makomba ane furo asina kuenzana (akakura kwazvo kana madiki)

Iyo furo gomba rakakura kwazvo, kuoma uye kuwanda kwechigadzirwa hakusi mwero, gomba rakavharwa richava gomba rakabatana, iyo micro hole inova gomba diki, zvimwe zvikamu zvinodonha kana zvimwe zvikamu hazvigone kutumirwa kumusoro.

Zvinokonzera:

(1) furo agglomeration kana zvimedu zvakanyanyisa;

(2) kusanganisa kusina kuenzana;

(3) mvura yakakwira yemubatanidzwa, mweya kana tsvina yakasanganiswa murubha;

(4) Kusakwana vulcanization, ramba uchigadzira makomba mushure mekuumbwa;

Countermeasures:

(1) tarisa iyo inoputika mumiriri, kana chiitiko che agglomeration chichifanira kusefa, zvidimbu zvakakashama zvinofanirwa kupwanywa, zvakasanganiswa zvakakwana (kana kuti zvakatetepa kupfuura) kuti zviparadzirwe zvakaenzana;

(2) nehunyoro hweajenti hunofanirwa kunge hwakanyanya kukwira mushure mekuoma, bvisa mweya kana tsvina murubha zvinhu, kuti zvinyatso vulcanized.

4. over-vulcanization kana under-vulcanization

(1) Kunyanya-vulcanization

General surface discoloration, diki eyelet, high hardness, product edge cracking, zvichibva pakushanda zvisina kufanira, kana tembiricha yakawandisa, nguva yakarebesa vulcanization kana kutadza kwechiridzwa, inofanira kutarisa kana mavharuvhu nezviridzwa zvine matambudziko, uyezve kunyatsoita mitemo yekushandisa.

(2) pasi pevulcanization

Kana vulcanization isingakwani, kudzvinyirirwa kwemukati kwepore kwakakura kudarika kudzvinyirira kwekunze mushure mokusiya mold, uye kana rubha ichiramba ichitumira makomba, chiedza chichaita kuti kuoma kwakaderera, simba risina simba uye deformation huru; rinorema richapaza maburi. Inofanira kutarisa kana pane dambudziko nechiridzwa uye valve, uye kunyatsoshandisa mitemo yekushanda.

Cherechedza: Zvigadzirwa zvefoam zvinodzora zviratidzo zvemhando

(1) Kuwanda kuri pachena, kudiki ndiko kuri nani;

(2) simba remagetsi rinowanzoita 0.5-1.6Mpa;

(3) static compression zvachose deformation;

(4) kuoma;

(5) kukanganisa elasticity;

(6) kuneta kunopfuurira kune simba;

(7) kuchembera bvunzo (70 madhigirii * 70 maawa; 100 madhigirii * 24 maawa);

(8) yakaderera tembiricha bvunzo.
