Umehluko phakathi kokuqhuma kokubumba nokuhlanganiswa

Ukushaya kokubumba nokuhlanganiswa komjovoziyizinqubo ezimbili zokubumba zepulasitiki ezihlukile ezahlukile ezicini eziningi. Okulandelayo ukuqhathanisa okuningiliziwe kwalezi zinqubo zokubumba ezimbili:

1, inqubo eyakhayo

Ukubumba okushayayo:

Ukubumba okushayayo, owaziwa nangokuthi ukugoba okuqhakaza okuyi-Hollow Blow, kuyindlela ethuthukisa ipulasitiki elisanda ngokushesha.

I-tubular placcity plastic etholwe ngokukhishwa noma ukuphathwa komjovo we-thermoplastic resin ibekwe esimweni sokuqhekeka ngenkathi kushisa (noma kufuthelwe esimweni esithambile). Ngemuva kokuvala isikhunta, umoya ocindezelwe ungeniswa ngokushesha ohlelweni lokuzithoba bese unamathela ngokuqinile odongeni lwangaphakathi lwesikhunta. Ngemuva kokupholisa futhi kudilizwe, kutholakala imikhiqizo ehlukahlukene eyize.

Ngokwendlela yokukhiqiza izisetshenziswa, ukuqhafaza okuvuthayo kungahlukaniswa kube yi-blow extlose yokubumba nokukhwabanisa, ngezindlela ezintsha ezisanda kuthuthukiswa kufaka phakathi ukubumba okuvuthayo kanye nokunwebeka kokubumba.

Ukubumba komjovo:

Ukubumba komjovo kubhekisele ekubumbeni komjovo wezinto zokwenza okukwi-thermoplastic.

Ukubumba kokuwohloka kuyinqubo yokuncibilika kwepulasitiki bese uyijova emgodini wefilimu. Lapho nje ipulasitiki elibunjiweyo lingena kubumba, lipholile futhi libunjiwe libe yisimo esithile ngokuya ngesampula ye-mold cavity, futhi ukwakheka okulandelayo kuvame umkhiqizo ophumelele ngaphambi kokufaka noma ukusetshenziswa njengomkhiqizo wokugcina.

Umshini wokubumba umjovo unezakhi ezimbili eziyisisekelo: idivaysi yokujova ngokuncibilika nokondla ngopulasitiki ekubumbeni, kanye nedivayisi yokuvala eyabanda. Umsebenzi wedivayisi yokubamba isikhunta ukuvala isikhunta ngaphansi kwengcindezi yomjovo bese ususa umkhiqizo. Idivaysi yokujova incibilikisa ipulasitiki ngaphambi kokulifaka kubumba, bese ilawula ingcindezi nesivinini sokufaka ukuncibilika kubumbiwe. Okwamanje kunemiklamo emibili yamadivayisi wokujova asetshenzisiwe: Screw Presizers noma amadivaysi amabili, kanye nezikulufo ezibuyisela.

2, ukusetshenziswa kwezinto ezingavuthiwe

Ukubumba okushayayo:

Izinto ezivuthiwe zokubumba okushayayo zivame ukuba yi-polyethylene, i-polyvinyl chloride, i-polypropylene, i-polystyrene, i-polycarbonastic, i-resin ye-polyethylene, phakathi kwayo i-polyethylene esetshenziswa kakhulu.

Ukubumba komjovo:

Izinto ezivuthiwe zokubumba umjovo zivame ukwenziwa i-thermoplastic noma iplastiki ye-thermoset.

3, uhlelo lokusebenza lomkhiqizo

Ukubumba okushayayo:

Ukubumba okushayayo kusetshenziswa kabanzi ezimbonini ezinjengamabhodlela, amathini, imikhiqizo yezingane, izimpahla zemidlalo, ukufakwa komkhiqizo wamakhemikhali, ukufakwa kwezinto ezibonakalayo, kanye nokupakishwa kwezinto ezibonakalayo. Iziqukathi ezitholwayo ezitholwayo nazo zisetshenziswa kabanzi njengeziqukathi zokufaka izimboni.

Ukubumba komjovo:

Ukubumba komjovo kusetshenziswa kabanzi emasimini anjengezimoto, izinto zasendlini, izingcingo eziphathwayo, amathoyizi, amathoyizi ahlukahlukene, amathoyizi, amafomu ahlukahlukene okukhiqiza anendlela yokukhiqiza ehlukahlukene embonini yemikhiqizo epulasitiki.

4, Izici zomkhiqizo

Ukubumba okushayayo:

Imikhiqizo ebunjiwe evuthayo imvamisa izakhiwo eziyize, ezinezindawo ezingalingani kanye nezinto zomoya.

Ukubumba komjovo:

Imikhiqizo Ebunjiwe Ebunjiwezivame ukuqina okuqinile ngekhwalithi ephezulu yokubukeka, ukunemba okunobukhulu, ukunemba okulinganiselayo, nokusebenza. Kodwa-ke, imikhiqizo ebunjiwe yokujova nayo ingahle ibe nezinkinga ezinjengezimpawu zesiliva, amamaki we-weld, imiphetho ye-flash, i-shrinkage, i-glue elahlekile, ukukhala, kanye nobucwebe.

Ngokufingqwa, ukuqhafaza kokubumba nokukholisa kokubumba kunomehluko omkhulu ezinhlelweni zokubumba, ukusetshenziswa kwezinto ezibonakalayo, izinhlelo zomkhiqizo, kanye nezimpawu zomkhiqizo. Ukukhethwa kwenqubo yokubumba ikakhulukazi kuncike kwizidingo ezithile kanye nezidingo zokuklama zomkhiqizo.
