Emashumini eminyaka adlule, i-Precise ibambe iqhaza ocwaningweni nasekukhiqizweni kwama-colorants, kufaka phakathiizingulube eziphilayo, odayi be-solvent, masterbatchfuthiukulungiswa kombala.Ukuhlanzeka nokusebenziseka kalula kuhlale kulindelwe abasebenzisi kulo mkhakha.Ngokukhula kwenqubomgomo yokuvikela imvelo emhlabeni wonke, kanye nezimfuneko ezengeziwe zentsha zendawo yokusebenza enhle, singabikezela ukuthi ukuzimisela kwabakhiqizi ukusebenzisa imibala evumelana nemvelo kuzokwanda ngokuqhubekayo.Inkampani yethu iphinde yabeka phambili umqondo ohlosiwe, okungukuthi ukuhlinzeka ngombala ohlanzekile futhi kulula ukuwusebenzisa, ukuze ilwele isikhundla sokuqala samaShayina.ukulungiswa kombalaumkhiqizi.Ngesikhathi esifanayo, sifuna ukulungisa kabusha isithombe esithi "Made in China".
Njengoba sazi, i-China ingelinye lamazwe asekuqaleni amakhulu ombala nodayi.Isamba sesivuno sonyaka sombala wasekhaya waseShayina singamathani ayi-170,000 kuya ku-190,000, okubalelwa ku-45% wokukhiqizwa kombala emhlabeni jikelele.Ngaphezu kwalokho, i-China iphinde ibe namandla amasha azayo eminyakeni emi-3-5 ezayo, azofinyelela kumathani angama-280,000 kuye kwangama-290,000 njengesamba sonyaka.Mayelana ne-color masterbatch e-China, lokho kukhuphuka futhi ngezinga lokukhula lonyaka cishe ngo-12%.Manje umthamo waminyaka yonke we-color masterbatch e-China usungaphezu kwamathani ayizigidi ezingu-1.7.Kodwa-ke, kuyadabukisa ukuthi i-masterbatch yombala yase-China ayithathi ingxenye yemakethe ehambisanayo emakethe ethumela ngaphandle, ngoba amabhizinisi e-masterbatch awavamisile ukuphuma ngisho amanye enamandla amakhulu okukhiqiza.Kokubili Intengo kanye nekhwalithi yemikhawulo yabo ye-masterbatch.
Ngokusho kokusetshenziswa kwesiko kanye nezici zentengo, siyazi ukuthi iningi lemasterbatchabakhiqizi basasebenzisa i-powder pigments, ngakho-ke yiziphi izinzuzo kanye namaphuthaizingulube ze-powder?Singathola esithombeni esingezansi.

Ngohlelo lokusebenza oludinga ukuhlakazeka okuphezulu, kuyadingeka ukuthi uhlakaze kuqala i-pigment eyimpushana kuqala, isibonelo, 'isigaba samanzi sokukhama' saziwa njengenye yezindlela zendabuko zokuhlakazeka kwangaphambili kwe-organic pigment.Besebenzisa le nqubo, abakhiqizi baqala kusukela esigabeni sekhekhe lesihlungi se-pigment, kulandelwa ukugaya, ukuguqulwa kwesigaba, ukwelashwa kwe-solvent, ukomisa kanye nochungechunge lwezinqubo zokuqedela inqubo yangaphambi kokusabalalisa.Izithwali ze-Polyolefin ezifana ne-Polyethylene wax zisetshenziswa njenge-ejenti ehlakazayo, ngakho-ke isikhathi sokugaya ibhola futhi side kakhulu.Kodwa isihluthulelo siwukwengeza i-ejenti ye-fluidization inqubo yokudlulisa ukushisa.Imikhiqizo ehlukene idinga ukungeza i-ejenti ehambisanayo ye-fluidization ngokuya ngesakhiwo sayo samakhemikhali.Isibonelo, i-azo pigment ephindwe kabili idinga ukusebenzisa usawoti we-quaternary ammonium noma insimbi (usawoti we-aluminium) kanye ne-Salt Lake-pigments esetshenziselwa i-acetyl amino benzene sulfuric acid, i-sodium hydroxide, njll. Futhi lungisa i-pH futhi ushukumise noma kunini.Inqubo inzima, futhi umphumela uthinteka kakhulu.Emabhizinisini okukhiqiza, lokhu kuyabulala kakhulu, kuzothinta kakhulu ukufika kwesikhathi kokulethwa kanye nokukhuthazwa komkhiqizo kanye nesivinini sokwandisa.
Izimo zochungechunge lwe-Preperse
Njengenye indlela ye-powdery pigment, ukulungiswa kwe-pigment kunezinzuzo ezivelele.Isici sayo sokuhlakazeka okuphezulu kanye nokungenalo uthuli kuhlangabezana nokuthambekela kobuchwepheshe bokukhiqiza nokuvikelwa kwemvelo kumabhizinisi anamuhla.
Nokho, yendabukoingulubentukulungiselelaakenzanga intuthuko enhle phakathi neminyaka edlule.Yiziphi izizathu zokuma okunjalo?
Isizathu sokuqala, nakuba bendabukoamalungiselelo ombalangcono umthamo wokuhlakazeka, izindleko ziphezulu kodwa hhayi ukusebenza kahle kwezindleko.Ngaphezu kwalokho, kune-ejenti ehlakazayo engaphezu kuka-50% (isb, i-wax) ngokwesikoamalungiselelo ombala, okusho ukuthi ukusetshenziswa kwabo ezidingweni ezinzima kunomkhawulo.Ngaphezu kwalokho, eminye imikhiqizo inqunyelwe izinhlamvu zofuzo, ngakho-ke amandla ayo okuhlakazeka athuthukiswa kancane futhi ukusebenza kombala akwenelisi neze.
Ngokuvela kwe'Preperse' uchungechungeukulungiswa kombalaskusuka ku-PNM, sithola indlela yokuxazulula izinkinga ezintathu ezingenhla.Kunokuqukethwe kwe-pigment engaphezu kuka-70%.'Preperse' uchungechunge.Ngaphezu kwalokho, i-'I-Preperse-S'uchungechunge lunokuhlakazeka okuvelele okwengeziwe okwethulwe i-polypropylene, i-polyester, inayiloni nezinye izinhlelo zokusebenza ezikhethekile.
Ukuthuthukisa okuqukethwe kwe-pigment kusho ukukhuphuka kwengxenye esebenzayo, futhi ingxenye yezisakazi ezifana nengcina emkhiqizweni iyancipha ngokufanayo.Ngokuhlanganisa okusebenzayo ngaphakathi, izindleko zethu ziseduze ne-powdery pigment.Ngakho-ke, izindleko zisobala futhi zenza imingcele eyinhloko yokwenza intengo yethu.
Ngaleso sikhathi, i-wax encane isho ukufuduka okuncane kanye nethuba eliphansi lesakhiwo kanye nokushintsha kwempahla.Ngamanye amazwi, uchungechunge lwethu lwe-'Preperse' luthuthukisa ukuhlakazeka ngezindleko eziphansi.
Njengoba sazi, ukuhlakazeka okungcono kuletha inzuzo eyengeziwe, umphumela omuhle kangaka wokubonwayo onokucwebezela okungcono, amandla aqinile njll. Abasebenzisi bangathola inzuzo eyengeziwe ngokusebenzisa umbala obala kodwa amandla afanelekile.
Ngaphandle kwalokho, i-dispersibility enhle iphinde ibonise inani eliyingqayizivele ngesikhathi sokukhiqiza.Ngokwesibonelo,Pigment Yellow 180, ukusebenza kwalesi sombala kungahlangabezana nezidingo ze-PP fiber, nokho kudinga i-pelletizing ephindaphindiwe ukuze kuzuzwe ukuhlakazeka okuhambisanayo kwezidingo ezinzima.Ngokwethiyori, ukuhlakazeka kwama-pigments kuncike 'kufuzo' lwazo -— ngisho nathi siyazi ukuthi umkhawulo ongaphezuluI-Pigment Yellow 180singafeza isicelo sethu, kodwa kufanele sisebenzise amandla amaningi okugunda kanye ne-ejenti ehlakazayo ukuze sifeze lokho okuhlosiwe.
Okuvelele kwe-pigment dispersibility ngaphansi kwe-x160 microscope
Ukuhlakazeka kwe-pigment okungalungile ngaphansi kwesibonakhulu se-x160
Ngakho-ke, siyazi ukuthi ukuhlakazeka okuphezulu akulula ukusondela kodwa kucela umzamo owengeziwe kanye nezindleko.Okokufaka okwengeziwe okufana nokuphindaphinda i-pelletizing, kuyamosha kumkhiqizi ekusebenzeni kahle kokukhiqiza kanye nethuba.
Eyethu'Preperse'uchungechunge lucabangela ngokugcwele izinkinga ezingokoqobo ezingenhla.Ukuze sikhulise ukuhlakazeka, sithatha 'ukuhlakazeka okusheshayo nokulula' njengemiqondo ewumongo yokwakheka komkhiqizo.Ngomgomo wokuhlakazeka okugcwele ngesikhathi esisodwa, senze inkomba yokulawula ikhwalithi eqinile: Konke'I-Preperse-S'uchungechunge luthobelana nezidingo ze-filament ngesikhathi esisodwa futhi i-FPV kufanele ibe ngaphansi kuno-1, ngaphansi kwesimo samameshe angu-1400, i-pigment engu-60g ngomshini we-FPV (40% pigment loading masterbatch dilute kuya ku-8%).
Ezimweni eziningi, ukwenza i-masterbatch ngokusebenzisa i-pelletizing yesikhathi esisodwa akwanele ukusondela ekusebenzeni okwamukelekayo kwe-FPV ezisetshenziswa eziqinile, ezifana ne-filament, ifilimu elincanyana njll. Uchungechunge lwe-'Preperse' lungenye yezixazululo ezifanele zalo mkhawulo.Zuza ekusebenzeni kwangaphambi kokuhlakazeka kanye nokuhlakazeka okuhle kakhulu, ukulungiswa kwe-pigment 'Preperse' kunomthelela ekwenzeni okuqukethwe kwe-pigment ephezulu i-mono masterbatch ethola iphesenti le-pigment ukusuka ku-40% ukuya ku-50%.Ngisho nama-pigments 'angenambala' angakwazi ukuhlakazeka kahle ngokofuzo aphinde aveze okuqukethwe kwe-pigment ephezulu ye-mono masterbatch.Ngokwesibonelo,I-Pigment Violet 23, eyaziwa ngokuthi i-pigment enzima kakhulu ehlakazeka kakhulu, thinakhiqizaPreperse Violet RL equkethe70% inani le-pigment futhi lenza u-40% we-mono masterbatch ngokugcwele, ne-FPV ku-0.146 bar/g (bona esithombeni esingezansi).
Ngaphezu kwalokho, wethu'Preperse'uchungechunge lungathola umphumela omuhle we-colorant ngaphandle kwemishini ephezulu ye-shear force.Ngokwesibonelo,Ukulungiselela 'Preperse' pigmentingasetshenziswa esikhundleni seumbalafuthii-mono masterbatchlapho wenza i-masterbatch noma umkhiqizo ogcinayo owenziwe ngokuqondile ngesikulufa esisodwa se-extruder.
Kubakhiqizi be-masterbatch, bangasusa inqubo yamanje yokwenza i-mono masterbatch noma i-SPC kodwa mathupha benze ukufanisa imibala.Ngale ndlela, abasebenzisi bonga isikhathi esiningi futhi bazuze ngokusebenza kahle okuphezulu.
