Ukusetyenziswa kwe-selsulose ether paste

1. Intshayelelo

Ukusukela ekufumaneni i-DYES esebenzayo, i-Sodium Algium (SA) ibe yeyona ndawo iphambili kwi-Dye ePrinta Printa i-CoTOPRICS.

Sebenzisa iindidi ezintathu zeI-seluploseI-CMC, i-HMC kunye ne-hecmc ilungiselelwe kwiSahluko 3 Njengoko i-Conter Sepreaktivent, bafakwa kwi-Dye Printa ngokulandelelana.

Intyatyambo. Iipropathi ezisisiseko kunye neepropathi zokuprinta zale ntembeko zintathu zavavanywa kwaye xa kuthelekiswa ne-SA, kunye neentsinga ezintathu zavavanywa.

Ukuprinta iipropathi zeevithamini.

I-2 yovavanyo

Izixhobo zovavanyo kunye neziyobisi

Izinto ezingafunekiyo kunye neziyobisi ezisetyenzisiweyo kuvavanyo. Phakathi kwazo, i-Dye Pring Priprings ishicile isetyenzisiwe kwaye ihlaziywe, njl.

Uthotho lwendlela ephathwe kwangaphambili ye-cotton ecocekileyo ye-cotton iwile, ukuxinana kwe-60 / 10cm × 50 / 10cm, i-21tex × 21tex

Ukulungiswa kwePasika yokuprinta kunye neMibala

Ukulungiswa kwePasika yokuprinta

Kwipasta yoqobo ye-SA, i-CMC, i-hec kunye ne-hecmc, ngokomyinge womxholo ohlukileyo, phantsi kweemeko ezinomdla

Ke, ngokuthe chu ukongeza ukuncamathisela emanzini, qhubeka nokushukumisa ixesha elithile, de i-paste yantlandlolo iyunifomu kwaye ibonakale, kwaye iyeke isitovu

Kwiglasi, vumelani ubusuku bonke.

Ukulungiswa kwePasika yokuprinta

Ukuqala ukunyibilikisa i-Urea kunye netyuwa yokudakumba kunye nexabiso elincinci lamanzi, emva koko wongeza i-dys esebenzayo echithwe emanzini, ubushushu kunye nokuvuselela igumbi lokuhlambela amanzi afudumeleyo

Emva kokuvuselela ixesha elithile, yongeza idayi etywine kwi-paste yokuqala kwaye ivuselele ngokuhlwa. Yongeza ukunyibilikisa de uqale ukuprinta

I-sodium elungileyo ye-sodium bicarbonate. Ifomula ye-Colaula yeMibala i: I-DYE ye-DEE 3%, ipasika yokuqala ye-80% (umxholo we-3%), iSodium Bicarbonate 3% 3%,

Ityuwa ye-Anti-Ungcoliseko s yi-2%, urea yi-5%, kwaye ekugqibeleni amanzi wongezwa kwi-100%.

Inkqubo yokuprinta

I-Cotton Ilaphu lokuPrinta iDye

I-100 ℃, i-10min) → Ukuhlamba amanzi ashushu (80 ℃) → Ukuhlamba amanzi okubandayo

Uvavanyo olusisiseko lokuSebenza lwePasika yantlandlolo

Cola uvavanyo lwexabiso

I-COSTES ezine ye-SA, CMC, i-Hec kunye ne-hecmc enemixholo eyahlukileyo eyomeleleyo ilungiselelwe, kwaye i-Brookfield DV-ⅱ

Uhlobo lwe-viscosity ye-paste nganye kunye nomxholo oqinisekileyo oqinisekileyo wavavanywa ngophawu, kwaye ijikajika le-viscofity yeyokwenza umyinge wokwenza i-paste.

ijika.

I-RUOOLOLOGY NOKUFUNDA IZELUNGELELWANO ZOKUGQIBELA

I-RHOOOLORT: MCR301 RHHEAMILREALRY isetyenziselwa ukulinganisa i-viscofity (η) yepasika yokuqala kumazinga okwahlukeneyo.

I-curve ye-Shear i-Shear ijika le-rubeology.

I-Viscofity Index: Isalathiso se-viscosity senziwa nguPvi, iPVI = η60 / η6, apho ¶60 kunye ne-η6 ngokulandelelana

I-viscosity ye-Colus yentsusa ilinganiswa yi-vismermeter ye-Brookfield DV-II kwindawo enye ye-rotor ye-60R / min kunye ne-6r / imiz.

Uvavanyo lokugcina amanzi

Ubunzima be-25g ye-paste yantlandlolo kwisicelo se-80ml beaker, kwaye ngokuthe ngcembe songeza i-25ml yamanzi ngelixa uvuselela ukwenza umxube.

Ixutywe ngokulinganayo. Thatha iPhepha lokuFihla uluhlu lobude obunobude be-10cm × 1cm, kwaye uqalise isiphelo sephepha elinamachaphaza, kwaye emva koko faka iphepha lokucoca, kwaye irekhodwe kwiphepha lemigqaliselo emva kwemizuzu engama-30.

Ukuphakama apho ukhula ukuphakama.

Uvavanyo olu-4 lweekhemikhali

Ukufumana i-DYE yokushicilela, vavanya ukuhambelana kwe-paste yokuqala kunye nezinye ii-dys zongezwa kwi-paste yokushicilela,

Oko kukuthi, ukungqinelana phakathi kwethuba lokuqala kunye nezinto ezintathu (iurea, iSodium Bicarbonate kunye neetyuwa ezichasene ne), amanyathelo ovavanyo oluthile ngolu hlobo lulandelayo:

.

Ixabiso le-viscosity elifunyenweyo lisetyenziswa njengesalathiso sesalathiso.

.

Isisombululo se-Irea (iqhekeza lesininzi), 3% i-Anti-Stainel Scova (iqhekeza lesininzi) kunye ne-6% sodium Bicarbonate (iqhekeza lesininzi)

25Ml yongezwa kwi-50g ye-paste yantlandlolo, ivuseleleke ngokulinganayo kwaye yabekwa kangangexesha elithile, emva koko lalinganisa i-viscosity yePasika. Okokugqibela, i-vickosity iya kulinganiselwa

Amaxabiso okubonisa ukuthelekiswa kwakuthelekiswa nesalathiso esihambelanayo, kunye nepesenti yokutshintsha kwe-viscofity ye-paste yokuqala ngaphambi nasemva kokudibanisa idayi nganye kunye nezinto zekhemikhali zabalwa.

Uvavanyo lokugcina imali

Gcina i-Conta i-Conta kubushushu begumbi (25 ° C) phantsi koxinzelelo oluqhelekileyo kangangeentsuku ezintandathu, kwaye lubale i-viscofity ye-pasika yentsusa emva kweentsuku ezi-6 xa kuthelekiswa nosuku lokuqala yiFomula 4- (1). Inqanaba lokusasazeka kwePasika nganye yoqobo ihlolwa ngumgangatho wokusasazeka njengesalathiso

Uzinzo lokugcina, incinci ukusasazeka, kungcono uzinzo logcino lwepasika yoqobo.

Uvavanyo lwexabiso lokuhamba

Okokuqala yomisa ilaphu lekotoni ukuba liprintwe kwisimo esihlala lisiphelo, silulinganise kwaye sirekhodishe njenge-M; emva koko yomisa ilaphu lekotoni emva kokuprinta ukuya kwisimo esihlala sinesidima, ubunzima kwaye sirekhodishe

yi-MB; Okokugqibela, ilaphu lekotoni eliprintiweyo emva kokuqhwaba, i-seap kunye nokuhlamba yomiswe kude kubunzima, ubunzima kwaye babhalwa njenge-MC

Uvavanyo lwezandla

Okokuqala, iilaphu zekotoni ngaphambi nasemva kokuprinta zisampulu njengoko kufuneka, kwaye emva koko isixhobo se-phabrometer se-fabrometer seliphuli sisetyenziselwa ukulinganisa ukuphathwa kweendwangu.

Imvakalelo yesandla ngendwangu ngaphambi nasemva kokuprinta yavavanywa ngokuthe ngqo ngokuthelekisa izandla ezintathu ezivakala iimpawu ezigudileyo, ukuqina kunye nokuthamba.
