Ukubumba i-Pulp, njengommeleli wokupakisha oluhlaza odumile, kuthandwa ngabanikazi bomkhiqizo. Enqubweni yokukhiqiza imikhiqizo ebunjiwe ye-pulp, isikhunta, njengengxenye eyinhloko, sinezidingo eziphakeme zobuchwepheshe zokuthuthukiswa nokuklama, ukutshalwa kwezimali okuphezulu, umjikelezo omude, kanye nobungozi obukhulu. Ngakho-ke, yimaphi amaphuzu abalulekile kanye nezinyathelo zokuphepha ekwakhiweni kwesikhunta sepulasitiki samaphepha? Ngezansi, sizokwabelana ngolwazi oluthile ekwakhiweni kwesakhiwo sokupakisha ukuze ufunde futhi uhlole ukwakheka kwesikhunta se-pulp.
01Ukwakha Isikhunta
Isakhiwo siqukethe isikhunta se-convex, isikhunta se-concave, isikhunta se-mesh, isihlalo sokubumba, isikhunta sangemuva, kanye negumbi lomoya. Isikhunta se-mesh siwumzimba oyinhloko wesikhunta. Njengoba isikhunta se-mesh silukwe ngezintambo zensimbi noma zepulasitiki ezinobubanzi obuyi-0.15-0.25mm, ayikwazi ukwakhiwa ngokuzimela futhi kufanele ifakwe ebusweni besikhunta ukuze isebenze.
Umgodi ongemuva wesikhunta umgodi ohlanganiswe ukujiya nokuma okuthile okuvunyelaniswe ngokuphelele nendawo yokusebenza yesikhunta, ngokuhlobene nesihlalo sokubumba. Isikhunta esiyi-convex ne-concave siyigobolondo elinodonga oluthile. Indawo yokusebenza yesikhunta ixhunywe emgodini ongemuva ngezimbobo ezincane ezisatshalaliswa ngokulinganayo.
Isikhunta sifakwe kwisifanekiso somshini wokubumba ngokusebenzisa isihlalo sokubunjwa, futhi ikamelo lomoya lifakwe ngakolunye uhlangothi lwesifanekiso. Ikamelo lomoya lixhunywe emgodini ongemuva, futhi kukhona neziteshi ezimbili zomoya ocindezelwe kanye ne-vacuum kuwo.
02Ukubumba isikhunta
Isikhunta sokubumba siyisikhunta esingena ngokuqondile ephepheni elimanzi lingenalutho ngemva kokwakheka futhi sinemisebenzi yokushisisa, ukucindezela, nokuphelelwa amanzi emzimbeni. Imikhiqizo eyenziwe ngesikhunta sokubumba inobuso obushelelezi, ubukhulu obunembile, ukuqina, nokuqina okuhle. I-tableware elahlayo yenziwa kusetshenziswa lesi sikhunta. Emaphaketheni embonini, ezinye izinto ezincane, ezinembayo, nezinkulu zipakishwa ungqimba ngongqimba, ngemikhiqizo yokupakisha esetshenziselwa ukubeka phakathi kongqimba ngalunye. Uma kusetshenziswa imikhiqizo eyenziwe nge-pulp, idinga ukwenziwa kusetshenziswa isikhunta sokubumba.
Kodwa-ke, imikhiqizo eminingi yokupakisha yezimboni isebenza ohlangothini olulodwa futhi ayidingi ukusetha ukushisa. Zingomiswa ngokuqondile. Isakhiwo sesikhunta sokubumba sihlanganisa isikhunta se-convex, isikhunta se-concave, isikhunta se-mesh, kanye nesici sokushisa. Isikhunta esiyi-convex noma se-concave esine-mesh mold sinezimbobo zokudonsa amanzi kanye ne-exhaust. Ngesikhathi sokusebenza, iphepha elimanzi elingenalutho liqala ukucwiliswa ngaphakathi kwesikhunta esibunjwayo, futhi u-20% wamanzi uyakhanywa futhi akhishwe. Ngalesi sikhathi, okuqukethwe kwamanzi ephepheni elimanzi elingenalutho kungu-50-55%, okubangela ukuthi amanzi asele ngemva kokuba iphepha elimanzi elingenalutho lishiswe ngaphakathi kwesikhunta ukuze livuthwe futhi likhishwe. Iphepha elimanzi elingenalutho liyacindezelwa, lomiswe, futhi libunjwe ukwenza umkhiqizo.
Isikhunta se-mesh ekubumbeni singadala izimpawu ze-mesh ebusweni bomkhiqizo, futhi isikhunta se-mesh singalimaza ngokushesha ngesikhathi sokukhishwa njalo. Ukuxazulula le nkinga, umklami wesikhunta uklame isikhunta samahhala se-mesh, esikhiqizwa kusetshenziswa i-copper based spherical powder metallurgy. Eminyakeni emibili edlule, ngemva kokuthuthukiswa okuningi kwesakhiwo kanye nokukhethwa kosayizi wezinhlayiya zempushana ezifanele, isikhathi sokuphila sesikhunta samahhala se-mesh esikhiqiziwe siphindwe izikhathi ezingu-10 kunesikhunta se-mesh, ngokunciphisa izindleko ezingu-50%. Imikhiqizo yephepha ekhiqizwayo inokunemba okuphezulu kanye nezindawo ezibushelelezi zangaphakathi nezingaphandle.
03Isikhunta Sokucindezela Okushisayo
Ngemuva kokoma, iphepha elimanzi elingenalutho liba ne-deformation. Lapho ezinye izingxenye zishintsha kakhulu noma zidinga ukunemba okuphezulu ekubukekeni komkhiqizo, umkhiqizo uba nenqubo yokubunjwa, futhi isikhunta esisetshenzisiwe sibizwa ngokuthi isikhunta sokubumba. Lesi sikhunta sidinga nezinto zokushisa, kodwa singenziwa ngaphandle kwesikhunta se-mesh. Imikhiqizo edinga ukubunjwa kufanele igcine umswakama ongu-25-30% ngesikhathi somiswa ukuze kube lula ukubunjwa.
Ekukhiqizeni, kunzima ukulawula okuqukethwe kwamanzi, okwenza kube nzima ngomkhiqizo ukuhlangabezana nezidingo zekhwalithi. Umkhiqizi uklame isikhunta sokubumba isifutho, futhi izimbobo zokufutha zenziwa esibunjeni esihambisana nezingxenye ezidinga ukubunjwa. Lapho usebenza, imikhiqizo ifakwa ekubunjweni kokubunjwa ngemuva kokumiswa kahle. Ngesikhathi esifanayo, imbobo yesifutho esibunjeni isetshenziselwa ukufutha ngokushisa ukucindezela imikhiqizo. Lesi sikhunta sithi siyafana nensimbi yesifutho embonini yezingubo.
04Ukudlulisa Isikhunta
Isikhunta sokudlulisa siyindawo yokugcina yokusebenza kuyo yonke inqubo, futhi umsebenzi waso oyinhloko ukudlulisa ngokuphepha umkhiqizo usuka kusikhunta esibalulekile esiwumsizi uye kuthreyi eyamukelayo. Ukuze uthole isikhunta sokudlulisa, idizayini yayo yesakhiwo idinga ukuba ibe lula ngangokunokwenzeka, ibe nezimbobo zokumunca ezihlelwe ngokulinganayo ukuze kuqinisekiswe ukuthi umkhiqizo ungakhanga kahle endaweni yesikhunta.
05Ukunquma Isikhunta
Ukuze wenze imikhiqizo ebunjiwe yephepha ihlanzeke futhi ibe yinhle, imikhiqizo eyenziwe ngephepha enezidingo eziphakeme zokubukeka ifakwe izinqubo zokusika onqenqemeni. Isikhunta se-Die cutting sisetshenziselwa ukunquma imiphetho enzima yemikhiqizo ebunjiwe yephepha, eyaziwa nangokuthi isikhunta sokusika onqenqemeni.
