Isikhundla esibalulekile kanye nomsebenzi we-polyester colorbatch embonini yemikhiqizo yepulasitiki ezicini ezine:
Imiphumela eyinhloko imi kanje:
(1) izici zombala ze-polyester colorbatch zivelele.
Ngenxa yokuxhumana okuqondile nomoya ohlelweni lokugcina nokusebenzisa ama-colorants, ukumuncwa komswakama, i-oxidation, i-agglomeration nezinye izenzakalo kulula ukwenzeka. Ukusetshenziswa okuqondile kombala kuzovela amaphuzu emibala ebusweni bemikhiqizo yepulasitiki, isigaba sombala simnyama, futhi umbala kulula ukufiphala. I-masterbatch yombala yenziwa ngomshini ekukhiqizeni, futhi umbala wacwengwa, futhi umbala, othwala i-resin kanye nezinsizi ezihlukahlukene zaxutshwa ngokugcwele ukuze kuhlukaniswe umbala emoyeni kanye nomswakama, ngaleyo ndlela kuthuthukise ukumelana nesimo sezulu sombala kanye nokwenza ngcono ukuhlakazeka nokuhlakazeka. amandla ombala we-colorant.
(2) I-polyester colorbatch ingenye yezinto ezibalulekile zokunquma ikhwalithi yemikhiqizo yepulasitiki esezansi nomfula.
Ingxenye yombala we-polyester masterbatch emikhiqizweni yepulasitiki ngokuvamile ingaphezu kuka-2%. Nakuba izindleko ezinkampanini ezansi nomfula ziphansi kakhulu, zinomthelela obalulekile ebuhleni naseqophelweni lemikhiqizo yepulasitiki. Imikhiqizo yepulasitiki ngokuvamile inkulu, ikhiqizwa ngokuqhubekayo, uma ukusetshenziswa kombala we-masterbatch umehluko wombala, ukuhlakazeka, ukumelana nokufuduka nezinye izinkomba zobuchwepheshe zingekho ezingeni elijwayelekile, ngokuvamile kuholela ekuwohlokeni kwekhwalithi yeqoqo lonke lemikhiqizo noma ngisho ne-scrap. , ngakho amakhasimende angaphansi komfula anaka kakhulu izinga lekhwalithi nokuzinza kwekhwalithi ye-masterbatch yombala. Ukuthuthukiswa nokujula kobuchwepheshe be-masterbatch color kukhuthaze inqubekelaphambili yezobuchwepheshe kanye nokuthuthukiswa kwezimboni embonini yemikhiqizo yepulasitiki.
(3) I-polyester colorbatch ingakhuthaza ukukhiqizwa okuhlanzekile kwemboni yemikhiqizo yepulasitiki ephansi.
Ukusetshenziswa kwe-masterbatch yombala ekukhiqizeni imikhiqizo yepulasitiki ngokuvamile kunganciphisa ukuchithwa kothuli, indle nokunye ukungcola, kuvikele impilo yabasebenzi, kodwa futhi kunciphise ukuchithwa kwama-colorants, ngokuhambisana nesiqondiso senqubomgomo kazwelonke yezimboni kanye nokuvikelwa kwemvelo okuluhlaza. umkhakha mkhuba. Amabhizinisi okukhiqiza amapulasitiki aphansi kulula ukubangela uthuli olundizayo lapho engeza futhi exuba izinto zendabuko zombala wempuphu, ezingase zidale ukulimala kwezempilo kubasebenzi bokukhiqiza, futhi zidinga ukuhlanza indawo yokusebenza kaningi, okuholela ekukhishweni kwamanzi angcolile e-pigment amaningi. Ngaphezu kwalokho, ukuhlakazwa kwezinto zendabuko zombala oyimpuphu ku-resin kubi kakhulu kunombala we-masterbatch, okuholela ekungezeni okwengeziwe ngaphansi kwezidingo ezifanayo zombala. Lapho uketshezi lombala lwengezwa futhi luxutshwa, kulula ukuchaphazeka nokuchichima, futhi lungase luphume ngesikhathi sokuhlanza, okungabangela kalula ukungcoliswa kwemithombo yamanzi.
I-masterbatch yombala isabalalisa umbala ku-resin yenkampani yenethiwekhi, futhi uthuli luncane enqubweni yokwengeza nokuxuba. Imvelo yokukhiqiza yebhizinisi lomkhiqizo ongezansi lisebenzisa umbala we-masterbatch coloring ihlanzekile, ukuhlanza kulula, futhi ukukhishwa kwamanzi angcolile kuyancishiswa, okuvumelana nenkambiso kanye nezidingo zokukhiqiza okuhlanzekile kwamabhizinisi okukhiqiza imikhiqizo yepulasitiki ephansi. I-masterbatch yombala inokuhlakazeka okuhle futhi inciphisa ukumosheka kombala.
(IV) ukunciphisa izindleko zokusetshenziswa okuhlanganisiwe komfula
Ngenxa yokuthi ukwakheka kwe-polyester colorbatch kufana nezinhlayiya ze-resin, kulula kakhulu futhi kunembe kakhulu ekukalweni, futhi ngeke kunamathele esitsheni lapho kuxutshwa, ngakho-ke kusindisa isikhathi sokuhlanza isitsha nomshini kanye nezinto zokusetshenziswa ezisetshenziswa umshini wokuhlanza. Inani elincane le-masterbatch yombala esebenzayo yengezwa enanini elikhulu lama-resin futhi acutshungulwe kanye ukuze abe umkhiqizo. Uma kuqhathaniswa nobuchwepheshe bepulasitiki obuguquliwe, izinto eziningi zidlula inqubo eyodwa encane yokucubungula kusuka ku-resin kuya kumkhiqizo, okungagcini nje kuphela ukulondoloza izindleko zokucubungula, kodwa futhi kunenzuzo kakhulu ukugcina ukusebenza komkhiqizo. I-masterbatch yombala esebenzayo ibonisa ithrendi ethile yokufaka esikhundleni samapulasitiki ashintshiwe.
