I-Plastic Net Khuluma ngomehluko phakathi kokubumba kokubumba nokuklolomba
September 04, 2023
Ukubumba okushayayo, owaziwa nangokuthi isikhunta esiqhakazile, iyindlela ethuthuka ngokushesha yokucubungula ngopulasitiki. Inqubo yokubumba ebumba yaqala ukukhiqiza ama-polyethylene aphansi empi yempi yezwe yesibili. Ngasekupheleni kwawo-1950s, ngokuzalwa kwe-polyethylene ephezulu kakhulu kanye nokuthuthukiswa kwemishini yokubumba ukushaya, ubuchwepheshe bokubumba obushayayo busetshenziswe kabanzi. Ukubumba kokujoka kuyindlela yokukhiqiza amajamo wemikhiqizo yezimboni. Imikhiqizo imvamisa ingumjovo obunjiwe kusuka enjoloba nepulasitiki. Okulandelayo uchungechunge oluncane lwe-jiuzhi.com ukukutshela ngomehluko phakathi kokubumba kokubumba nokuhlobisa. Kunamaphuzu amathathu aphambili:
1. Inqubo yehlukile, ukukhuthala okushayayo kungumjovo + ovunguzayo; Ukubumba komjovo kungumjovo + wokucindezela; Ukubumba okuguqukayo kungukuphazamiseka + kwengcindezi; Ukubumba okushayayo kumele kube nekhanda elishiywe ukukhishwa kwepayipi legesi, futhi ukubumba komjovo kumele kube nesigaba sesango. Ukuqamba ama-rolomolding kumele kusikwe ngaphandle kokunqunywa.
2. Ngokuvamile, ukukhuluma umjovo kuwumgogodla oqinile, nokubumba okushayayo nangokuqamba ama-rolomolding akulona imikhondo elingenalutho. Ingaphezulu lezingxenye ezibunjiweyo zomjovo liqhakazile, futhi ingaphezulu lokubumba okushayayo kanye ne-rolomolding akulingani. Ukubumba okushayayo kanye nokuqamba ama-rolomolding okungenani kuvunguza ukubumba. Kukhona umlomo ovunguzayo. Lokhu ukuqhathanisa okujwayelekile.
3. I-Shrinkage yepulasitiki kanye nezici zayo ezithonya izici zama-thermoplastics ukuthi bayanda ngemuva kokushisa, banciphise ngemuva kokupholisa, futhi ivolumu lizoncipha ngemuva kokucindezela. Enqubweni yokubumba komjovo, ipulasitiki ebilisiwe iqala ukufakwa emgodini womuntu, futhi ngemuva kokugcwaliswa, ukuncibilika kupholile futhi kuqiniswe, futhi ukuncipha kwengxenye kususelwa ekubumbeni, futhi kuthiwa yingxenye yeplastiki kwakha i-shrinkage. Usayizi wengxenye yepulasitiki usazoshintsha kancane kusukela ngesikhathi isikhunta sisuswa esimweni esizinzile. Ushintsho olulodwa ukuqhubeka nokuncipha. Le shrinkage ibizwa ngeShrikage emuva. Okunye ukuhluka yile ukuthi amanye ama-hygroscopic plastics avuvukala ngenxa yokutholwa komswakama. Isibonelo, lapho okuqukethwe kwamanzi kwe-nylon 610 kungu-3%, ukukhuphuka kobukhulu kungu-2%; Futhi lapho okuqukethwe kwamanzi kwe-fiber fiber kuqiniswa i-nylon 66 kungama-40%, ukukhuphuka kobukhulu kungu-0.3%. Kepha indima eyinhloko yi-shrinkage eyenziwe ngayo.
