ukubumba umjovo kuthinte ingcindezi yangemuva ?

Umphumela wokucindezela emuva uvuliwe umjovo udini kubaluleke kakhulu, futhi kuthinta ngqo ukugcwaliswa kokuncibilika kanye nekhwalithi yezingxenye zepulasitiki.

(1) Kufanelekile ingcindezi emuva ingathuthukisa ikhwalithi yemikhiqizo

①Ingakwazi ukuhlanganisa ukuncibilika emgqonyeni, ukwandisa ukuminyana, futhi uthuthukise umthamo womjovo, isisindo somkhiqizo nokuzinza kwe-dimensional;

②Igesi ekuncibilikeni ingaba “akhishwe” ukunciphisa ukuqhakaza komoya kanye namabhamuza angaphakathi ebusweni bomkhiqizo, futhi uthuthukise ukufana kweglosi;

③Yehlisa isivinini sokuhlehla sesikulufu ukuze uncibilike emgqonyeni wenze ipulasitiki ngokugcwele, ukwandisa ukufana kokuxutshwa kwe-toner, masterbatch bese uncibilika, futhi ugweme ukuxubana kombala emkhiqizweni;

④ Ukwandisa kahle ingcindezi yangemuva kungathuthukisa ukushwabana kwendawo yomkhiqizo kanye neglue egijima eduze komkhiqizo.;

⑤Kungakhuphula umswakama wokuncibilika, ngcono ikhwalithi ye-plasticization yokuncibilika, futhi uthuthukise i-fluidity yokuncibilika lapho ugcwalisa isikhunta, futhi ubuso bomkhiqizo awunayo imigqa yeglue ebandayo.

(2) Umthelela wokucindezela okwedlulele emuva emikhiqizweni

①Ingcindezi yokuncibilika ekugcineni komgqomo iphezulu kakhulu, izinga lokushisa lempahla liphezulu, futhi i-viscosity iyancipha. Ukugeleza okubuyela emuva kokuncibilika ku-screw groove kanye nokwanda kokugeleza kokuvuza phakathi kombhobho nesikulufu kuzonciphisa ukusebenza kahle kwepulasitiki.;

②Okwamapulasitiki anokunganyakazi kahle kwe-thermal (njenge-PVC, I-POM, njll.) noma ama-colorants, izinga lokushisa lezinto ezincibilikisiwe liyakhula futhi isikhathi sokushisa emgqonyeni siyanda, okubangela ukubola okushisayo, noma izinga lokushintsha kombala liyakhula, kanye nombala ongaphezulu kanye nokucwebezela komkhiqizo Kuba kubi kakhulu;

③Ingcindezi yangemuva iphezulu kakhulu, isikulufu sihlehla kancane, futhi isikhathi sokubuya kwangaphambi kwepulasitiki side, okuzokwandisa isikhathi somjikelezo futhi kunciphise ukusebenza kahle kokukhiqiza;

④Ingcindezi yangemuva iphezulu futhi ingcindezi yokuncibilika iphezulu. Ngemva kokuba i-glue ijovwe, umlomo wombhobho ujwayele ukuncibilika amathe. Lapho ingcina ijovwe ngokuzayo, izinto ezibandayo kumgijimi we-nozzle zizovimba umlomo noma amabala abandayo azovela kumkhiqizo;

⑤Ngesikhathi se- umjovo udini umshini inqubo yokusebenza, umbhobho uyavuza ngenxa yokucindezela okukhulu emuva, okumosha izinto zokusetshenziswa futhi kubangele indandatho yokushisisa eduze nombhobho ukuthi ishise;

⑥ Ukuguga komshini we-pre-plastic mechanism kanye ne-screw barrel kuyakhuphuka.

(3) Umthelela wengcindezi ephansi emuva emikhiqizweni

① Uma ingcindezi yangemuva iphansi kakhulu, isikulufu sihlehla ngokushesha kakhulu, ukuminyana kokuncibilika okugeleza ekugcineni komgqomo wefeni kuncane (okuxekethile), futhi kunomoya omningi;

②Kuzoholela kukhwalithi embi ye-plasticization, umthamo womjovo ongazinzile, kanye nezinguquko ezinkulu esisindweni somkhiqizo nosayizi womkhiqizo;

③Ubuso bomkhiqizo buzovela buncipha, izimbali zomoya, imigqa yezinto ezibandayo, isicwebezelisi esingalingani nezinye izenzakalo ezingathandeki;

④ Amabhamuza kulula ukuvela ngaphakathi komkhiqizo, futhi i-periphery namathambo omkhiqizo kulula ukuhamba futhi awanelisekile ngeglue.

(4) Indlela yokuqondisa yokusetha ingcindezi emuva

I ukucindezela emuva kokubunjwa komjovo kufanele ilungiswe ngokuya ngezakhiwo zezinto ezingavuthiwe, izimo ezomile, isakhiwo somkhiqizo kanye nezimo zekhwalithi. Ingcindezi yangemuva ngokuvamile ilungiswa ku-3-15kg/cm3. Lapho indawo yomkhiqizo inokuqhuma komoya okuncane, ukuxuba umbala, ukuncipha kanye nezinguquko ezinkulu kusayizi womkhiqizo nesisindo, ingcindezi yangemuva inganyuswa ngokufanelekile. Lapho umbhobho uyavuza, amathe, iyancibilika ishise kakhulu futhi ibole, umkhiqizo uyashintsha umbala, futhi ukubuya kwempahla kuhamba kancane kakhulu, ungacabangela ngokufanelekile ukunciphisa ukucindezela emuva.
