Ukubaluleka koShicilelo lweThickener

Printing thickener: Luhlobo lwesityebi esisetyenziswa kakhulu kushishino lokushicilela.Ekushicileleni, izinto ezimbini eziphambili, iglue kunye nokunamathisela umbala, zisetyenziswa.Kwaye ngenxa yokuba phantsi kwe-shear ephezulu, ukuhambelana kuya kuncitshiswa, ngoko ke kuyimfuneko ukusebenzisa i-thickener ukunyusa ukuhambelana kwezinto zokushicilela, emva koko kusetyenziswa i-thickener yokushicilela.

Ukushicilela i-thickener ye-china indima ephambili kukubonelela ngeempawu ezintle ze-rheological, ukudlulisa iglu okanye ukuncamathisela kombala kwisikrini sokushicilela kunye ne-roller yokushicilela kwilaphu, ukudibanisa idayi kunye nefayibha, kwaye uqinisekise ulwandlalo lwepateni yokushicilela.eyahlukileyo.Ipateni icacile, umbala ugqamile kwaye ufana;xa idayi ilungisiwe, imveliso yokusabela kunye nentsalela zisuswa ngokulula kwinkqubo esezantsi, ukwenza ilaphu lizive lithambile.Kuyabonakala ukuba i-printing thickener idlala indima ebaluleke kakhulu kushishino lokushicilela.

Imbali yoPhuhliso:

Izityebi zokushicilela zinembali ende yophuhliso.I-slurry eyayisetyenziswa kwakudala yayisisitatshi okanye i-modified starch.Le ngqimba ibizwa ngokuba yi-natural thickener, kodwa le nto yokushicilela ineendleko eziphezulu zokusetyenziswa, ubunzulu bombala ophantsi, ukucaca okungahambi kakuhle, kunye nokumelana Ukukhawuleza ekuhlambeni kwakhona kubi, kwaye ukuthungwa kwelaphu akwanelisi.Okwangoku, ezi ntlobo ze-thickeners ziye zapheliswa ngokuthe ngcembe.Kwakungoo-1950 kuphela apho abantu bavelisa i-A-state pulp, nto leyo eyenza ukuba ubugcisa bokushicilela busetyenziswe ngokubanzi.I-state pulp thickener yenziwe nge-high-speed emulsification ye-kerosene kunye namanzi phantsi kwesenzo se-emulsifier.Ngenxa yokuba esi sityebi siqulethe ngaphezu kwe-50 # i-kerosene, kunye nesixa esikhulu esisetyenzisiweyo, sibangela ungcoliseko olunzima kwi-atmosfera kunye nomngcipheko wokuqhuma.Ukongezelela, ukuhambelana kwe-paste yokushicilela akulula ukulungelelanisa, kwaye iphunga le-kerosene liya kuhlala phezu kwengubo emva kokushicilela.Ngoko ke abantu abakaneliseki ngolu hlobo lwe-printing thickener.

Ushicilelo Thickener

Ngeminyaka yee-1970, abantu baqala ukuphuhlisa nokuvelisa ii-thickeners zokwenziwa.Ukufika kwee-thickeners zokwenziwa kuye kwakhuthaza kakhulu uphuhliso lwemveliso yoshicilelo kwaye kwaphakamisa iteknoloji yokushicilela kwinqanaba elitsha.Isombulula iingxaki zokungcoliseka kwendalo kunye nokhuseleko.Ngaphezu koko, i-thickener yokwenziwa ineenzuzo zesiphumo esihle sokuqina, ukuhamba kakuhle kunye nokugcinwa, ukulungiswa okulula, ulwandlalo olucacileyo, umbala oqaqambileyo njalo njalo.

Ukuhlelwa kwe-thickener yokushicilela:

Kukho iintlobo ezininzi zee-thickeners zokushicilela, okwangoku zahlulwe zibe ziindidi ezimbini eziphambili: i-nonionic kunye ne-anionic.I-nonionic thickeners ininzi i-polyethylene glycol derivatives ye-ether.I-thickeners enjalo kufuneka ibe noluhlu olubanzi, kodwa umphumo wokuqina umbi, ubungakanani bokudibanisa bukhulu, kwaye inani elithile le-kerosene lisafuneka.Ngoko ke, oku kukwanciphisa uphuhliso lwayo olongezelelweyo.

I-anionic thickener yi-polymer electrolyte compound, eyi-copolymer ene-crosslinking yokukhanya.Ibonakaliswa yi-viscosity ephantsi, isiphumo esihle sokuqina, uzinzo oluhle, ukongezwa okuphantsi, i-rheology elungileyo, kunye nefuthe lokushicilela.kulungile.Ezona zixhaphakileyo ziikhompawundi zepolyacrylic.Okwangoku, eyona nto ixhaphakileyo ye-polyacrylic acid ikhompawundi yi-anionic polymer electrolyte.Isebenzisa indlela ye-emulsion polymerization ukwenza i-polymerize iimonomers ezinyibilikayo emanzini zibe yimveliso yobisi.Kukulungele ukwenza i-paste kunye nokuzinza kwe-original paste kunye nombala wombala.Ilaphu eliprintiweyo lithambile kwi-touch kwaye linokugcinwa ixesha elide.Yiloo nto esihlala siyithetha malunga ne-PTF thickener.
