Iindaba zeNkampani

Ziziphi iindlela eziqhelekileyo zokubumba iplastiki?

1) Unyango lwangaphambili (ukomisa ngeplastiki okanye ufake unyango lwangaphambi kokutshisa)

2) Ukubumba

3) Umatshini (ukuba kuyimfuneko)

4) Ukuchukumisa kwakhona (de-flashing)

5) INdibano (ukuba kuyimfuneko) Qaphela: Ezi nkqubo zintlanu zingentla kufuneka zenziwe ngokulandelelana kwaye azikwazi ukuguqulwa.

Izinto ezichaphazela ukuchaneka komgangatho wokubumba iplastiki:

1) Impembelelo yesantya sokucutheka kwezinto eziluhlaza

Okukhona ukucutheka kwezinto ezikrwada, kokukhona kusezantsi ukuchaneka kwemveliso. Emva kokuba izinto zeplastiki ziqiniswe okanye zitshintshwe ngokuzaliswa kwe-inorganic, izinga layo le-shrinkage liya kuncitshiswa kakhulu ngamaxesha angama-1-4. Iimeko zokucutshulwa kwePlastiki (izinga lokupholisa kunye noxinzelelo lwenaliti, iindlela zokulungisa, njl.), uyilo lwemveliso kunye noyilo lokungunda kunye nezinye izinto. Ukubumba ukuchaneka kweendlela ezahlukeneyo zokubumba kukwindlela ehlayo: ukubumba inaliti > i-extrusion > ukubunjwa kwesitofu > ukubunjwa kwe-extrusion > ukubunjwa koxinzelelo > ukubumba ikhalenda > ukwakhiwa kwevacuum

2) Impembelelo ye-creep yezinto eziluhlaza (i-creep yi-deformation yemveliso phantsi koxinzelelo). Ngokubanzi: Izinto zePlastiki ezinokuxhathisa okulungileyo: i-PPO, i-ABS, i-PC kunye neplastiki eyomeleziweyo okanye egcweleyo. Emva kokuba izinto zeplastiki ziqiniswe okanye zitshintshwe ngokuzaliswa kwe-inorganic, ukuchasana kwayo kwe-creep kuya kuphuculwa kakhulu.

I-3) Impembelelo yokwandiswa komgca wezinto eziluhlaza: i-coefficient yokwandisa umgca (i-coefficient yokwandisa i-thermal)

I-4) Impembelelo yezinga lokufunxa kwamanzi kwizinto eziluhlaza: Emva kokufunxa amanzi, umthamo uya kwanda, okubangela ukwanda kobukhulu, obuchaphazela kakhulu ukuchaneka komgangatho wemveliso. (Ukufunxwa kwamanzi kwemathiriyeli ekrwada nako kuya kuchaphazela ngokunzulu iipropathi ezibonakalayo kunye nezomatshini zemathiriyeli ekrwada emva kokuba zicutshungulwe zibe ziinxalenye.)

Iiplastiki ezinamanzi aphezulu: ezifana ne-PA, i-PES, i-PVA, i-PC, i-POM, i-ABS, i-AS, i-PET, i-PMMA, i-PS, i-MPPO, i-PEAK Nikela ingqalelo kwiimeko zokugcina kunye nokupakishwa kwezi plastiki.

5) Impembelelo yokudumba kwezinto eziluhlaza Isilumkiso! ! Ukuchasana kwe-solvent yezinto eziluhlaza kuya kuchaphazela kakhulu ukuchaneka komgangatho wemveliso kunye neempawu ezibonakalayo kunye nezomatshini zemveliso. Kwiimveliso zeplastiki ezinxibelelana nemidiya yekhemikhali, sebenzisa izixhobo zeplastiki ezinemithombo yeendaba ezingenakubangela ukuba zidumbe.

6) Impembelelo yokugcwalisa: Emva kokuba izinto zeplastiki ziqiniswe okanye zitshintshwe ngokuzaliswa kwe-inorganic, ukuchaneka komgangatho wemveliso yeplastiki kunokuphuculwa.
