M'zaka makumi angapo zapitazi, Precise yakhala ikuchita nawo kafukufuku ndi kupanga ma colorants, kuphatikizaorganic inki, zosungunulira utoto, masterbatchndikukonzekera pigment. Ukhondo ndi wosavuta kugwiritsa ntchito nthawi zonse amayembekeza ogwiritsa ntchito pamakampani awa. Chifukwa cha kuchuluka kwa mfundo zoteteza zachilengedwe padziko lonse lapansi, komanso kuchuluka kwa zomwe achinyamata amafuna kuti pakhale malo abwino ogwirira ntchito, titha kunena kuti kufunitsitsa kwa opanga kugwiritsa ntchito mitundu yoteteza zachilengedwe kukuchulukirachulukira. Kampani yathu idayikanso lingaliro lomwe likuyembekezeredwa, lomwe ndikupereka utoto woyera komanso wosavuta kugwiritsa ntchito, kuti tiyesetse kukhala woyamba ku China.kukonzekera pigmentwopanga. Panthawi imodzimodziyo, tikufuna kukonzanso chithunzi cha "Made in China".
Monga tikudziwira, China ndi limodzi mwa mayiko oyambirira a pigment ndi utoto. Zokolola zonse zapachaka za utoto waku China zimakhala pafupifupi matani 170,000 mpaka 190,000, zomwe zimatengera pafupifupi 45% ya kupanga pigment padziko lonse lapansi. Kuphatikiza apo, China ilinso ndi mphamvu zatsopano zomwe zikubwera zaka 3-5 zikubwerazi, zomwe zidzafika matani 280,000 mpaka 290,000 pachaka. Ponena za masterbatch ku China, izi zikukweranso ndi chiwonjezeko chapachaka pafupifupi 12%. Tsopano mphamvu yapachaka ya masterbatch yamitundu ku China ikupitilira matani 1.7 miliyoni. Komabe, ndizachisoni kwambiri kuti mtundu waku China wa masterbatch sutenga gawo lofananira pamsika wogulitsa kunja, chifukwa mabizinesi a masterbatch satuluka kawirikawiri ngakhale ena amakhala ndi mphamvu zopanga zambiri. Onse Mtengo ndi mtundu wa malire awo a masterbatch.
Malinga ndi kugwiritsa ntchito miyambo ndi mtengo zinthu, tikudziwa kuti ambiri amasterbatchopanga akugwiritsabe ntchito inki ya ufa, ndiye ubwino wake ndi zotaniutoto wa pigment? Tikhoza kupeza m'munsimu chithunzi.

Pakuti ntchito amene amafuna mkulu kubalalitsidwa, m'pofunika Pre-mwaziritse ufa pigment choyamba, mwachitsanzo, 'kufinya madzi gawo' amadziwika ngati mmodzi wa miyambo chisanadze kumwazikana njira za organic pigment. Pogwiritsa ntchito njirayi, opanga amayamba kuchokera pagawo la keke la pigment, ndikutsatiridwa ndi kugaya, kutembenuka kwa gawo, mankhwala osungunulira, kuyanika ndi njira zingapo kuti amalize ndondomeko yobalalika. Zonyamulira za Polyolefin monga sera ya Polyethylene zimagwiritsidwa ntchito ngati chobalalitsira, motero nthawi yophera mpira ndi yayitali kwambiri. Koma chinsinsi ndi kuwonjezera wothandizira fluidization mu ndondomeko kutentha kutengerapo. Zogulitsa zosiyanasiyana zimayenera kuonjeza wothandizira wa fluidization molingana ndi kapangidwe kake ka mankhwala. Mwachitsanzo, pawiri azo pigment ayenera kugwiritsa ntchito quaternary ammonium mchere kapena zitsulo (zitsulo zotayidwa mchere) ndi Salt Lake-pigments ntchito acetyl amino benzene sulfuric acid, sodium hydroxide, etc. Komanso kusintha pH ndi kusonkhezera nthawi iliyonse. Njirayi ndi yovuta, ndipo zotsatira zake zimakhudzidwa kwambiri. Kwa mabizinesi opanga, izi ndi zakupha kwambiri, zidzakhudza kwambiri nthawi yobweretsera ndi kukwezedwa kwazinthu komanso kuthamanga kwakukula.
Mawonekedwe a Preperse series
Monga m'malo mwa powdery pigment, kukonzekera pigment kuli ndi ubwino wake. Mawonekedwe ake owoneka bwino komanso opanda fumbi amakumana ndi ukadaulo wopanga & kuteteza chilengedwe kwa mabizinesi amakono.
Komabe, chikhalidwenkhumbantkukonzekerasichinapite patsogolo kwambiri m'zaka zapitazi. Zifukwa zoyima motere ndi chiyani?
Chifukwa choyamba ndi, ngakhale chikhalidwekukonzekera pigmentkupititsa patsogolo mphamvu ya dispersibility, mtengo wake ndi wokwera koma osati mtengo wabwino. Komanso, pali oposa 50% dispersing wothandizira (mwachitsanzo, sera) mu chikhalidwekukonzekera pigment, zomwe zikutanthauza kuti kugwiritsa ntchito kwawo pazofunikira zazikulu ndizochepa. Kuphatikiza apo, zinthu zina zimakhala zochepa chifukwa cha chibadwa chawo, motero kuthekera kwawo kwa dispersibility kumakhala bwino pang'ono ndipo mawonekedwe amitundu sakhala okhutiritsa.
Ndi zikamera wa'Preperse' mndandandakukonzekera pigmentskuchokera ku PNM, timapeza njira yothetsera mavuto atatuwa. Pali mitundu yopitilira 70% ya pigment yonse'Preperse' mndandanda. Komanso, a'Preperse-S'mndandanda uli ndi dispersibility zambiri zomwe zidayambitsa polypropylene, polyester, nayiloni ndi ntchito zina zapadera.
Kupititsa patsogolo mtundu wa pigment kumatanthauza kuwonjezereka kwa zinthu zogwira mtima, ndipo gawo la zosakaniza monga sera muzinthuzo zimachepetsedwa mofanana. Pokhala ndi mphamvu zambiri mkati, mtengo wathu uli pafupi ndi pigment ya powdery. Chifukwa chake, mtengo wake ndi wowonekera ndipo umapanga magawo akulu pakupanga mitengo yathu.
Pakadali pano, sera yocheperako imatanthauza kusamuka kochepa komanso kuthekera kochepera kwa kapangidwe & kusintha kwa makina. Mwanjira ina, mndandanda wathu wa 'Preperse' umapangitsa kuti dispersibility ndi mtengo wotsika.
Monga tikudziwira, dispersibility bwino kumabweretsa phindu, kotero zabwino zithunzi zotsatira ndi bwino bwino, amphamvu mphamvu etc. Ogwiritsa angapeze phindu owonjezera pogwiritsa ntchito pigment zochepa koma mtundu mphamvu.
Kupatula apo, dispersibility yabwino imawonetsanso phindu lapadera panthawi yopanga. Mwachitsanzo,PYellow 180, machitidwe a pigment iyi akhoza kukwaniritsa zofunikira za PP CHIKWANGWANI, komabe zimafunika mobwerezabwereza pelletizing kukwaniritsa dispersibility lolingana zofunika kwambiri. Mwachidziwitso, kupezeka kwa ma pigment kumadalira pa 'jini' -- ngakhale tikudziwa kuti malire apamwamba aPigment Yellow 180titha kukwaniritsa zopempha zathu, koma tiyenera kuyika mphamvu zambiri zometa ubweya ndi wobalalitsa kuti tikwaniritse zomwe tikufuna.

Kuwonongeka kwa pigment pansi pa x160 microscope
Choncho, tikudziwa kuti dispersibility pamwamba si kophweka kufikako koma kupempha khama owonjezera ndi mtengo. Zowonjezera monga kubwereza ma pelletizing, ndizowononga kwa opanga pakupanga bwino komanso mwayi.
Zathu'Preperse'mndandanda akuganizira bwino mavuto omwe ali pamwambawa. Pofuna kukweza kufalikira, timatengera 'kubalalika mwachangu komanso kosavuta' ngati mfundo zazikuluzikulu za kapangidwe kazinthu. Ndi cholinga cha dispersibility kwathunthu ndi pelletizing nthawi imodzi, tinapanga okhwima ulamuliro khalidwe index: Onse'Preperse-S'mndandanda ukugwirizana ndi zofunikira za filament ndi nthawi imodzi pelletizing ndipo FPV iyenera kukhala yotsika kuposa 1, pansi pa ma meshes 1400, 60g pigment kupyolera mu makina a FPV (40% pigment loading masterbatch kuchepetsa ku 8%).
Nthawi zambiri, kupanga masterbatch kudzera pa pelletizing nthawi imodzi sikokwanira kuyandikira ntchito yovomerezeka ya FPV pakugwiritsa ntchito mwamphamvu, monga filament, filimu yopyapyala ndi zina zambiri. Mndandanda wa 'Preperse' ndi imodzi mwa njira zothetsera vutoli. Kupindula ndi machitidwe obalalitsidwa kale komanso kufalikira kwabwino kwambiri, kukonzekera kwa mtundu wa 'Preperse' kumathandizira kuti pakhale pigment yayikulu kukhala mono masterbatch yomwe imapeza kuchuluka kwa pigment kuchokera pa 40% mpaka 50%. Ngakhale ma pigment ena 'opanda mikwingwirima' omwe sangathe kubalalika bwino mwachibadwa amawonetsanso mtundu wamtundu wa mono masterbatch. Mwachitsanzo,Pigment Violet 23, yomwe imadziwika kuti mtundu wovuta kwambiri wosabalalika, ifekupangaSinthani Violet RL zomwe zili70% pigment mtengo ndipo imapanga 40% mono masterbatch, ndi FPV pa 0.146 bar/g (onani pa chithunzi pansipa).
Komanso, athu'Preperse'mndandanda ukhoza kupeza zotsatira zabwino za colorant popanda zida zamphamvu zometa ubweya wambiri. Mwachitsanzo,'Preperse' pigment kukonzekeraangagwiritsidwe ntchito m'malo mwamtundundimono masterbatchpopanga masterbatch kapena terminal product yomwe mwachindunji ndi single screw extruder.
Kwa opanga ma masterbatch, atha kuchotsa njira yomwe ilipo popanga mono masterbatch kapena SPC koma okhawo omwe amafananiza mitundu. Mwanjira iyi, ogwiritsa ntchito amasunga nthawi yochulukirapo ndikupindula ndikuchita bwino kwambiri.
