Ungawulawula kanjani umehluko wombala wemikhiqizo yomjovo?

Ithiphu Yomqondo: Ukwahluka kombala kuyinkinga evamile ekubunjweni komjovo. Akujwayelekile ukuthi umshini wokubumba umjovo uklwebeke emabhuntshini ngenxa yokuhluka kombala wezingxenye ezifanayo. Kunezinto eziningi ezithinta umehluko wombala, kufaka phakathi i-resin eluhlaza, i-Colour Masterbatch (noma i-color color).

Umehluko wombala uyisici esijwayelekile ekubunjweni komjovo. Akujwayelekile ukuthi imishini yokubumba inaliti ifakwe emabhetshini ngenxa yokuhluka kombala kwezingxenye ezifanayo. Kunezinto eziningi ezithinta umehluko wombala, njenge-resin eluhlaza, i-Colour Masterbatch (noma i-color color), ingxube ye-color masterbatch nezinto ezingavuthiwe, inqubo yokubumba umjovo, umshini wokubumba injekishini, nokunye. Ngoba ifaka izici eziningi ezahlukahlukene, ubuchwepheshe bokulawula umehluko wemibala bubuye baziwa njengobunye bobuchwepheshe obunzima kakhulu bokukwazi ukwakha inaliti yokubumba. Kwinqubo yangempela yokukhiqiza, ngokuvamile silawula umehluko wemibala kusuka kulezi zinto eziyisithupha ezilandelayo.



1. Susa ithonya lomshini wokubumba womjovo kanye nezici zokubumba



Ukukhetha umshini wokujova onomthamo ofanayo nomkhiqizo womjovo, uma umshini wokujova unenkinga ye-engele efile yezinto ezibonakalayo, kungcono ukubuyisela imishini. Ukuze umehluko wombala obangelwe uhlelo lokuphonsa kanye nokudla okuphelele kokufayo, kungaxazululwa ngokugcinwa kwengxenye yokufa ehambisanayo. Kuyadingeka ukuxazulula izinkinga zemishini yokufaka umjovo kanye nezikhunta ukuze uhlele ukukhiqizwa futhi unciphise ubunzima benkinga.



2. Susa ithonya le-resin eluhlaza kanye ne-masterbatch yombala



Ukulawulwa kwezinto ezingavuthiwe kuyisihluthulelo sokuxazulula ngokuphelele inkinga yokuxhashazwa kwe-chromatic. Ngakho-ke, ikakhulukazi ekukhiqizweni kwemikhiqizo enemibala ekhanyayo, asikwazi ukunganaki ithonya elisobala lokuqina okuhlukile kwe-resin eluhlaza ekushintsheni kombala kwemikhiqizo.



Ngenxa yokuthi iningi labakhiqizi abakha umjovo abakhiqizi ama-masterbatches epulasitiki noma ama-color masterbatches uqobo, ukunakwa kungagxila ekuphathweni kokukhiqiza nasekuhlolweni kwezinto ezibonakalayo ezingavuthiwe. Lokho wukuthi, ukuqinisa ukuhlolwa kwezinto ezingavuthiwe kugcinwe; ukukhiqiza umkhiqizo ofanayo, umkhiqizi ofanayo, i-brand masterbatch efanayo ne-masterbatch yombala kufanele yamukelwe ngangokunokwenzeka;



Okwamakhompiyutha amakhulu, kufanele sisebenzise isheke nokuhlola ngaphambi kokukhiqizwa ngobuningi, hhayi kuphela ngokuhlolwa kokugcina, kodwa futhi kulokhu kuqhathaniswa, uma umehluko wombala ungemkhulu, singacabanga njengabaqeqeshiwe, njengoba ama-bandch masterbatches anombala omncane umehluko, singaphinda sixube ama-masterbatches bese siwasebenzisa ukuze sinciphise umehluko wombala obangelwa ukuhlanganiswa okungalingani kwama-masterbatches ngokwawo. Ngasikhathi sinye, futhi sidinga ukugxila ekuhlolweni kokuqina kwama-resins angaphekiwe kanye nama-masterbatches. Kulabo abanokuzinza okushisayo kwamafutha, siphakamisa ukuthi abakhiqizi bashintshe.



3. Susa ithonya lokuxuba okungalingani kwe-masterbatch ne-Masterbatch



Ukuxuba kabi ama-masterbatches epulasitiki ngama-masterbatches kungenza futhi umbala wemikhiqizo uguqulwe. Lapho i-masterbatch ne-masterbatch kuxutshwe ngokulinganayo futhi kudluliselwa e-hopper ngokusebenzisa ukudonsa, i-masterbatch idluliselwa kalula odongeni lwe-hopper ngenxa kagesi omile, okuzobangela ukushintshwa kwenani le-masterbatch kumjikelezo wokubumba umjovo, ngaleyo ndlela kuholele umbala umehluko.



Lesi simo singasombululwa ngokufaka imvuthuluka esetshenziselwa izinto zokusetshenziswa ibe ama-hoppers bese uyixuba ngesandla. Ekwenzeni imikhiqizo engeyona eyisijobelelo ngokufaka i-color color, indlela ephumelela kakhulu akuyona ukusebenzisa umshini wokugaya, kepha ukusebenzisa owomile wokomisa nomoya wendlela yokudla yokuvikela umehluko wombala obangelwa ukwahlukaniswa kwe-color color ne-masterbatch.



4. Umphumela wokwehlisa izinga lokushisa emgqonyeni ekuchithweni kwe-chromatic



Ekhiqizweni, kuvame ukuhlangana ukuthi amazinga okushisa emgqonyeni aguquka kakhulu ngenxa yokwehluleka kwendandatho yokushisa noma ukushiswa isikhathi eside kwengxenye yokulawula ukufudumala, kuholele ekuxoshisweni kwe-chromatic. Ukuxoshwa kwe-chromatic okubangelwa yilolu hlobo lwezizathu kulula ukwahlulela. Ngokuvamile, ukuhanjiswa okuvela ku-chromatic okubangelwa ukwehluleka kokufudumeza indandatho kuhambisana nokwenzakala kwepulasitiki engalingani, ngenkathi ukudubula isikhathi eside okungalawulwa kwengxenye yokulawula ukufudumala kuvame ukuhambisana nemboni yegesi yomkhiqizo, ukucwilisa okukhulu nokubanga. Ngakho-ke, kuyadingeka ukuhlola ingxenye yokufudumeza kaningi ekukhiqizweni, bese uyifaka esikhundleni futhi uyilungise ngesikhathi lapho ingxenye yokushisa ilimele noma ingasebenzi, ukuze kunciphise amathuba alolu hlobo lokuxoshwa kwe-chromatic.



5. Yehlisa ithonya lokulungiswa kwenqubo yomjovo



Lapho ulungisa imingcele yenqubo yokujova yezizathu ezingezona ze-chromatic, izinga lokushisa lomjovo, ingcindezi emuva, umjikelezo wokulimala kanye nenani le-masterbatch yombala akufanele liguqulwe ngangokunokwenzeka. Ngasikhathi sinye, ithonya lokuguqulwa kwamapharamitha wenqubo kumbala kufanele libhekwe. Uma kutholakala umehluko wombala, kufanele uguqulwe ngesikhathi.



Ngokusemandleni akho, gwema ukusebenzisa ubuchwepheshe bokubumba umjovo ngejubane eliphezulu lomjovo, ingcindezi ephezulu yangemuva nezinye izinto ezibangela umphumela oqinile we-shear, futhi uvikele umehluko wombala obangelwa ukweqiwa kwendawo ngokweqile noma ukubola okushisayo. Lawula ngokuqinile ukushisa kwengxenye ngayinye yokufudumeza yomgqomo, ikakhulukazi ingxenye yokufudumeza yomsindo kanye nozzle oseduze.



6. Kahle ithonya lokushisa emgqonyeni kanye nenani le-masterbatch ekushintsheni kombala womkhiqizo



Ngaphambi kokulungisa umehluko wombala, kuyadingeka ukwazi ukuthambekela kombala womkhiqizo ushintsha ngokushisa kanye ne-masterbatch. Ama-masterbatches ahlukene anemithetho ehlukile yokuguqula umbala ngokushintshwa kwezinga lokushisa noma inani lama-masterbatches. Umthetho oguqukayo unganqunywa ngenqubo yokuhlolwa kombala.



Akunakwenzeka ukulungisa umehluko wombala ngaphandle kokuthi umthetho oguqukayo wombala we-masterbatch waziwa, ikakhulukazi uma kusetshenziswa i-masterbatch entsha.
