Intshayelelo kwi-Masterbatch yoMbala eSetyenziselwe ukuTshanisa iiGranules zePlastiki

Yintoni umbala masterbatch?

Umbala we-masterbatch, luhlobo olutsha lombala okhethekileyo wepolymer, okwaziwa ngokuba yi-pigment preparation.

Iqulunqwe zizinto ezintathu ezisisiseko: i-pigment okanye idayi, i-carrier kunye ne-additive. Yeyona aggregate ye-pigment engaguqukiyo kakhulu okanye idayi edityaniswe ngokufanayo kwiresin. Inokubizwa ngokuba yi-pigment concentrate, ngoko ke amandla ayo ombala aphezulu kune-pigment ngokwayo.

Ngamafutshane, i-masterbatch yombala yi-aggregate ye-pigment okanye idayi edityaniswe ngokufanayo kwi-resin.

Ngawaphi amacandelo asisiseko sombala we-masterbatch?

Ubume obusisiseko bombala we-masterbatch:

1. I-pigment okanye idayi

Ii-pigments zohlulwe zibe yi-organic pigments kunye ne-inorganic pigments.

I-pigments eziphilayo ezisetyenziswa ngokuqhelekileyo zezi: i-phthalocyanine ebomvu, i-phthalocyanine eluhlaza okwesibhakabhaka, i-phthalocyanine eluhlaza, ebomvu ngokukhawuleza, i-macromolecular ebomvu, i-macromolecular yellow, isigxina ephuzi, i-purple esisigxina, i-azo ebomvu njalo njalo.

I-pigments ye-inorganic esetyenziswa ngokuqhelekileyo zezi: i-cadmium ebomvu, i-cadmium emthubi, i-titanium dioxide, i-carbon black, i-iron oxide ebomvu, i-iron oxide etyheli njalo njalo.

2. Cumxhasi

Umthwali yimatrix yombala we-masterbatch. I-masterbatch yombala okhethekileyo ngokubanzi ikhetha i-resin efanayo ne-resin yemveliso njengomphathi, ukuhambelana kwezi zibini yeyona nto ingcono, kodwa kwakhona kuqwalaselwe ubumanzi bomthwali.

3. Dipersant

Ukukhuthaza i-pigment ihlakazeke ngokulinganayo kwaye ayisekho i-condensed, indawo yokunyibilika ye-dispersant kufuneka ibe ngaphantsi kune-resin, kwaye i-resin inokuhambelana kakuhle, kwaye i-pigment inobudlelwane obuhle. Ezona zixhaphazi zisetyenziswa kakhulu yi-polyethylene low molecular wax kunye ne-stearate.

4. Adiditive

Okufana ne-flame retardant, ukukhanya, i-antibacterial, i-antistatic, i-antioxidant kunye nezinye iindidi, ngaphandle kokuba isicelo somthengi, ngokuqhelekileyo asinazo ezongezo ezingentla kwi-masterbatch yombala.

Ziziphi iintlobo kunye namabanga e-masterbatch yombala?

Iindlela zokuhlela ze-masterbatch yombala ziqhele ukusetyenziswa ngolu hlobo lulandelayo:

Ukuhlelwa ngokweumthwali: ezifana PE master, PP master, ABS master, PVC master, EVA master, njl.

Ukuhlelwa ngokusetyenziswa: njenge-injection master, i-blow molding master, i-spinning master, njl.

Uluhlu ngalunye lunokwahlulwa lube ngamabanga ahlukeneyo, afana nala:

1. I-masterbatch yombala wenaliti ephucukileyo:Isetyenziselwa iibhokisi zokupakisha zokuthambisa, iithoyi, iindawo ezivaliweyo zombane kunye nezinye iimveliso eziphambili.

2. I-masterbatch yombala wenaliti eqhelekileyo:Isetyenziselwa iimveliso zeplastiki zemihla ngemihla, izitya zamashishini, njl.

3. I-masterbatch yombala wefilimu yokuvuthela ephucukileyo:isetyenziselwa ukubumba umbala weemveliso ezibhityileyo kakhulu.

4. I-masterbatch yombala wefilimu evuthelwayo eqhelekileyo:isetyenziselwa ukupakisha iingxowa jikelele, iingxowa ezilukiweyo zivuthela imibala.

5. Umbala ojikelezayo we-masterbatch:isetyenziselwa umbala we-textile fiber spinning, umbala we-pigment particles ilungile, ugxininiso oluphezulu, amandla ombala anamandla, ukumelana nobushushu okulungileyo, ukuchasana nokukhanya.

6. Umgangatho ophantsi masterbatch:esetyenziselwa ukuvelisa iimveliso ezikumgangatho ophantsi ezineemfuno zomgangatho ophantsi wombala, ezinje ngeetoti zenkunkuma, izitya zomgangatho ophantsi, njl.

7. Iqela elikhethekileyo lombala:ngokohlobo lweplastiki olucaciswe ngumsebenzisi kwiimveliso, khetha iplastiki efanayo nesithwali esenziwe ngombala obalaseleyo. Ngokomzekelo, i-PP master kunye ne-ABS master ngokulandelelana bakhetha i-PP kunye ne-ABS njengabathwali.

8. I-Universal colorbatch:i-resin (ngokuqhelekileyo i-PE enendawo ephantsi yokunyibilika) iphinda isetyenziswe njenge-carrier, kodwa ingasetyenziselwa umbala wezinye ii-resin ngaphezu kwe-resin carrier.

I-masterbatch yombala wendalo yonke ilula kwaye ilungile, kodwa inezingxaki ezininzi. Inqanaba lokumelana nobushushu be-masterbatch yombala okhethekileyo ngokuqhelekileyo lifanelekile kwiiplastiki ezisetyenziswa kwimveliso, kwaye zinokusetyenziswa kwiqondo lokushisa eliqhelekileyo. Amanqanaba ahlukeneyo okutshintsha kwebala anokubangelwa kuphela phantsi kweemeko ezilandelayo, enye iqondo lokushisa liphuma kuluhlu oluqhelekileyo, elinye ixesha lokuphumla lide kakhulu.

9. Xa kuthelekiswa nombala wegranulation, umbala we-masterbatch unezi nzuzo zilandelayo:

(1) Umbala kunye nokulungiswa kwemveliso kugqityiwe kanye, ukuphepha inkqubo yokufudumeza igranulation kunye nombala weplastiki, ukukhusela umgangatho weemveliso zeplastiki kulungile.

(2) Inkqubo yokuveliswa kweemveliso zeplastiki yeyona ilula kakhulu.

(3) Inokonga umbane omninzi.

Kutheni usebenziseumbala masterbatch?

 Ukusebenzisa umbala masterbatch kunezi nzuzo zilandelayo:

1. Ukusasazwa ngcono kwe-pigment kwiimveliso

Umbala we-masterbatch yi-aggregate eyenziwe ngokuqhotyoshela inani elikhulu le-pigment ngokulinganayo kwintlaka.

Kwinkqubo yokuveliswa kombala we-masterbatch, i-pigment kufuneka icocwe ukuze kuphuculwe ukusasazeka kunye namandla ombala we-pigment. Umthwali we-masterbatch yombala okhethekileyo ufana neplastiki yemveliso, kwaye unokudibanisa okulungileyo. Emva kokufudumeza kunye nokunyibilika, iinqununu ze-pigment zingahlakazwa kakuhle kwiplastiki yemveliso.

2. Mgcina uzinzo lwekhemikhali yebala

Ukuba i-pigment isetyenziswe ngokuthe ngqo, i-pigment iya kubamba amanzi kunye ne-oxidizing ngenxa yokudibanisa ngqo nomoya ngexesha lokugcinwa kunye nokusetyenziswa. Emva kokuba yi-masterbatch yombala, umthwali we-resin uya kuhlukanisa i-pigment emoyeni nasemanzini, ukuze umgangatho we-pigment uhlale ungatshintshi ixesha elide.

3. Qinisekisa ukuzinza kombala wemveliso

I-masterbatch yombala ifana ne-particle ye-resin, efanelekileyo ngakumbi kwaye ichanekile kumlinganiselo. Xa ukuxuba, akuyi kubambelela kwisitya, kwaye ukuxuba kunye ne-resin kufana ngakumbi, ngoko kunokuqinisekisa ukuzinza kwesixa sokongeza, ukwenzela ukuba kuqinisekiswe ukuzinza kombala wemveliso.

4. Khusela impilo yomsebenzisi

I-pigment ngokuqhelekileyo ingumgubo, okulula ukubhabha xa idityanisiwe kwaye ixutywe, kwaye iya kuchaphazela impilo yomqhubi emva kokuphefumlelwa ngumzimba womntu.

5. Gcina okusingqongileyo kucocekile kwaye izixhobo ezingenabala

6. Inkqubo elula, kulula ukuyijika umbala, igcina ixesha kunye nezinto eziluhlaza

Ngenxa yebala kwinkqubo yogcino kunye nokusetyenziswa koqhagamshelwano ngqo nomoya, ngoko kuya kubakho ukufunxa ukufuma, oxidation, clumping kunye nezinye izinto, ukusetyenziswa ngqo kuya kuvela kumphezulu iimveliso zeplastiki amabala umbala, umbala mnyama, umbala lula. ukucima, kwaye kubangele uthuli olubhabhayo xa luxutywa, luchaphazela impilo yomsebenzisi.

Kwaye i-masterbatch yombala kwinkqubo yokuvelisa ngokucutshungulwa ngoomatshini, i-pigment yacokiswa, i-pigment kunye ne-resin carrier, i-dipersant ixutywe ngokupheleleyo, ukuze i-pigment kunye nomoya, ukwahlukaniswa kwamanzi, ngaloo ndlela kuphuculwe ukumelana nemozulu ye-pigment, ukuphucula ukusasazeka kunye nemibala. amandla e-pigment, umbala oqaqambileyo. Ngenxa yobume obufanayo bombala we-masterbatch kunye ne-resin pellets, kulula ngakumbi kwaye ichanekile kumlinganiselo. Xa udibanisa, awuyi kubambelela kwisitya, ngoko ke ugcina ixesha lokucoca isitya kunye nomatshini kunye nezinto ezisetyenziswa kumatshini wokucoca.
