Kumashumi eminyaka adlulileyo, i-Precise ibizibandakanya kuphando kunye nokuveliswa kwemibala, kubandakanyaii-pigments eziphilayo, iidayi ezinyibilikayo, masterbatchkwayeukulungiswa kwebala. Ukucoceka kwaye kulula ukuyisebenzisa kusoloko kulindelwe ngabasebenzisi kweli shishini. Ngokunyuka komgaqo-nkqubo wokukhuselwa kokusingqongileyo kwihlabathi jikelele, kunye neemfuneko ezingakumbi nangakumbi zolutsha ukuze kubekho imeko-bume efanelekileyo yokusebenza, sinokuqikelela ukuba ukukulungela kwabavelisi ukusebenzisa imibala ehambelana nokusingqongileyo kuya kukhula ngokuqhubekayo. Inkampani yethu ikwabeke phambili ingcamango ekujoliswe kuyo, oko kukuthi, ukubonelela ngococeko olunjalo kwaye kulula ukuyisebenzisa umbala, ukuze sizabalazele isikhundla sokuqala saseTshayina.ukulungiswa kwebalaumenzi. Ngelo xesha, sifuna ukuphinda sihlaziye umfanekiso othi "Yenziwe eChina".
Njengoko sisazi, iChina lelinye lawona mazwe makhulu eebala kunye nedayi. Isivuno esipheleleyo sonyaka se-pigment yasekhaya yase-China imalunga ne-170,000 ukuya kwi-190,000 yeetoni, ibalwa malunga ne-45% yemveliso ye-pigment yehlabathi. Ngaphaya koko, i-China ikwanesakhono esitsha esiza kule minyaka mi-3-5 izayo, eya kuthi ifikelele kwi-280,000 ukuya kwi-290,000 yeetoni njengemali yonyaka. Ngokumalunga nombala we-masterbatch e-China, nayo inyuka ngesantya sokukhula ngonyaka malunga ne-12%. Ngoku umthamo wonyaka wombala we-masterbatch e-China ungaphezulu kwe-1.7 yezigidi zeetoni. Nangona kunjalo, kulusizi ukuba i-masterbatch yemibala yaseTshayina ayithathi kwisabelo semakethi esihambelanayo kwimakethi yokuthumela ngaphandle, kuba amashishini e-masterbatch awafane aphume kwaye amanye anomthamo omkhulu wemveliso. Zombini ixabiso kunye nomgangatho wemida yabo ye-masterbatch.
Ngokutsho ukusetyenziswa isiko kunye nexabiso imiba, siyazi ukuba uninzimasterbatchabavelisi basasebenzisa ii-pigments zomgubo, ngoko ke ziziphi iingenelo kunye neziphenei-pigments yomgubo? Singafumanisa kumfanekiso ongezantsi.

Kwisicelo esifuna usasazo oluphezulu, kuyimfuneko ukusasaza kwangaphambili i-pigment engumgubo kuqala, umzekelo, 'isigaba samanzi sokucudisa' saziwa njengenye yeendlela zemveli zangaphambili zokusasazwa kwe-organic pigment. Ukusebenzisa obu buchule, abavelisi baqala ukusuka kwinqanaba lekhekhe le-pigment filter, lilandelwa ngokusila, ukuguqulwa kwesigaba, unyango lwe-solvent, ukomisa kunye noluhlu lweenkqubo zokugqiba inkqubo yokusasazwa kwangaphambili. Izithwali zePolyolefin ezifana newax yePolyethylene zisetyenziswa njengearhente yokusasaza, ngoko ke ixesha lokugaya ibhola lide kakhulu. Kodwa isitshixo kukongeza i-arhente ye-fluidization kwinkqubo yokudluliselwa kobushushu. Iimveliso ezahlukeneyo kufuneka zongeze i-ejenti ehambelanayo ye-fluidization ngokwemichiza yazo. Ngokomzekelo, i-azo pigment ephindwe kabini kufuneka isebenzise ityuwa ye-quaternary ammonium okanye isinyithi (i-aluminium salts) kunye ne-Salt Lake-pigments esetyenziselwa i-acetyl amino benzene sulfuric acid, i-sodium hydroxide, njl. Inkqubo inzima, kwaye imveliso ichaphazeleka kakhulu. Kumashishini emveliso, oku kuyingozi kakhulu, kuya kuchaphazela ngokunzulu ukuhanjiswa kwexesha kunye nokukhuthazwa kwemveliso kunye nesantya sokwandisa.
Iimilo zothotho lwe-Preperse
Njengenye indlela ye-powdery pigment, ukulungiswa kwe-pigment kuneenzuzo ezibalaseleyo. I-dispersibility yayo ephezulu kunye neempawu ezingenalo uthuli ziyahlangabezana nentsingiselo yetekhnoloji yemveliso kunye nokhuseleko lokusingqongileyo kumashishini angoku.
Noko ke, eyemveliipigmentukulungiselelaakenzanga nkqubela phambili kule minyaka idlulileyo. Ziziphi izizathu zokuma okunjalo?
Isizathu sokuqala kukuba, nangona ngokwemveliamalungiselelo ebalaukuphucula umthamo we-dispersibility, iindleko ziphezulu kodwa azikho kakuhle iindleko-ukusebenza. Ukongeza, kukho ngaphezu kwe-50% ye-arhente yokusabalalisa (umzekelo, i-wax) ngokwemveliamalungiselelo ebala, okuthetha ukuba isicelo sabo kwiimfuno ezinzima silinganiselwe. Ngaphezu koko, ezinye iimveliso zisikelwe umda ngabalinganiswa bazo bemfuza, ngoko ke amandla abo okuhlakazeka aphuculwa kancinci kwaye ukusebenza kombala akwanelisi.
Ngokuvela kwe'Preperse' seriesukulungiswa kwebalasukusuka kwi-PNM, sifumana indlela yokusombulula ezi ngxaki zintathu zingasentla. Kukho ngaphezu kwe-70% ye-pigment content ngokupheleleyo'Preperse' series. Ngaphezu koko, i'Preperse-S'Uthotho lune-dispersibility egqwesileyo ethe yasungulwa kwi-polypropylene, i-polyester, inayiloni kunye nezinye izicelo ezikhethekileyo.
Ukuphucula umxholo we-pigment kuthetha ukwanda kwe-constituent esebenzayo, kunye nenani lezinto ezisasazayo ezifana ne-wax kwimveliso iyancitshiswa ngokuhambelanayo. Ngokwakheka okusebenzayo ngakumbi ngaphakathi, ixabiso lethu lisondele kwibala lomgubo. Ke ngoko, iindleko ziselubala kwaye zenza ezona parameters ziphambili zokwenza amaxabiso ethu.
Ngeli xesha, iwax encinci ithetha ukufuduka okuncinci kunye nokuba nokwenzeka okusezantsi kwesakhiwo kunye nokutshintsha kwepropathi yoomatshini. Ngamanye amazwi, uthotho lwethu lwe 'Preperse' luphucula ukusasazeka ngexabiso eliphantsi.
Njengoko sisazi, i-dispersibility engcono izisa inzuzo eninzi, isiphumo esihle sokubonwayo esinobukhazikhazi obungcono, amandla anamandla njl.njl. Abasebenzisi banokufumana inzuzo eyongezelelweyo ngokusebenzisa i-pigment encinci kodwa amandla afanelekileyo ombala.
Ngaphandle koko, i-dispersibility elungileyo ikwabonisa ixabiso elikhethekileyo ngexesha lemveliso. Umzekelo,Pigment emthubi 180, ukusebenza kwale pigment kunokuhlangabezana neemfuno zePP fiber, nangona kunjalo idinga i-pelletizing ephindaphindiweyo ukufezekisa i-dispersibility ehambelanayo kwiimfuno ezinzima. Ithiyori, i-pigments i-pigments ixhomekeke kwi 'Gene' - nokuba siyayazi ukuba umda ongaphezulu weI-Pigment Yellow 180singasizalisekisa isicelo sethu, kodwa kufuneka sibeke amandla amaninzi okucheba kunye ne-arhente yokusasaza ukuphumeza injongo.

Isiphene se-pigment dispersibility phantsi kwe-x160 microscope
Ke, siyazi ukuba i-dispersibility ephezulu akulula ukufikelela kuyo kodwa sicela umzamo owongezelelweyo kunye neendleko. Igalelo elongezelelweyo elifana nokuphinda i-pelletizing, liyinkcitho kumvelisi ekusebenzeni ngempumelelo kunye nethuba.
Yethu'Preperse'series iqwalasela ngokupheleleyo ezi ngxaki zingasentla. Ukuze siphakamise ukusasazeka, sithatha 'ukukhawuleza nokulula ukusasaza' njengezona ngqikelelo zoyilo lwemveliso. Ngenjongo ye-dispersibility epheleleyo ngexesha elinye i-pelletizing, senze isalathisi solawulo olungqongqo: Zonke'Preperse-S'uchungechunge luthobela iimfuno ze-filament ngexesha elinye kunye ne-FPV kufuneka ibe ngaphantsi kwe-1, phantsi kwemeko ye-meshes ye-1400, i-pigment ye-60g ngomatshini we-FPV (i-40% ye-pigment yokulayisha i-masterbatch iyancipha ukuya kwi-8%).
Kwiimeko ezininzi, ukwenza i-masterbatch ngokusebenzisa i-pelletizing yexesha elinye akwanelanga ukusondela kwintsebenzo eyamkelekileyo ye-FPV kwizicelo ezingqongqo, ezifana ne-filament, ifilimu encinci njl. Uxhamlo kwintsebenzo yaphambi kokusasazwa kunye nokusasazeka okugqwesileyo, ukulungiswa kwe-pigment 'Preperse' kunegalelo ekwenzeni umxholo we-pigment ephezulu i-mono masterbatch efumana ipesenti yebala ukusuka kwi-40% ukuya kwi-50%. Kwanezinye ii-pigments 'ezingenangqondo' ezingakwaziyo ukusasazwa kakuhle ngokwemfuza nazo zivelisa umxholo webala eliphezulu le-mono masterbatch. Umzekelo,I-Pigment Violet 23, eyaziwa njengeyona pigment enzima-ihlakazeka, thinavelisaPreperse Violet RL equlatheI-70% yexabiso le-pigment kwaye yenza ngokupheleleyo i-40% ye-mono masterbatch, kunye ne-FPV kwi-0.146 bar / g (jonga kumfanekiso ongezantsi).
Ngaphandle koko, wethu'Preperse'uchungechunge lunokufumana isiphumo esihle sombala ngaphandle kwezixhobo eziphezulu zokucheba. Umzekelo,Ukulungiselela i-pigment 'Preperse'ingasetyenziswa njengokutshintshaumbalakwayemono masterbatchxa usenza i-masterbatch okanye imveliso yetheminali ngokuthe ngqo ngesikrufu esinye.
Kubavelisi be-masterbatch, banokususa inkqubo yangoku yokwenza i-mono masterbatch okanye i-SPC kodwa bazenzele ngokwabo ukuthelekisa imibala. Ngale ndlela, abasebenzisi bagcina ixesha elininzi kwaye bazuze ngokusebenza okuphezulu.
