Namhlanje uXiaobian ukuthetha nawe malunga nomkhenkce weacetic acid kunye noshicilelo kufuneka sithethe izinto.

Abantu abaninzi abazi ukuba yintoni ukuprinta kunye nokudaya, okukwabizwa ngokuba yidayi kunye nokugqiba. Luhlobo lwendlela yokucutshungulwa kwelaphu, ubukhulu becala ukuprintwa kwelaphu esilisebenzisa kubomi bemihla ngemihla. Kwaye kwinkqubo yokuprinta kunye nokudaya, ngokuqhelekileyo sisebenzisa iviniga emuncu ye-ice. Ke yintoni i-iced iviniga? Iviniga ye-glacial ikwabizwa ngokuba yi-acetic acid, eyaziwa ngokuba yi-acetic acid, i-organic monic acid, iyona nto iphambili yokusetyenziswa kweviniga yemihla ngemihla. Kwiqondo lobushushu begumbi, indawo yayo yokukhenkceza yi-16.6℃, kwaye iya kuba yikristale engenambala emva kokuqina.

Ngoko kutheni sisebenzisa i-acetic acid ye-glacial kwinkqubo yokushicilela kunye nokudaya? Isizathu sokuprinta kunye nokudaya usebenzisa i-acetic acid yeglacial? Kutheni ukongeza i-glacial acetic acid kwinkqubo yokuprinta kunye nokudaya? Oku kungenxa yokuba xa siprinta kwaye sidaya, ixabiso le-pH le-disperse polyester yedayi kufuneka libe phakathi kwe-4-6, ngoko kufuneka sisebenzise i-acetic acid ye-glacial ukuhlambulula idayi. Ngokomzekelo, xa siprinta kwaye sidaya, amanzi okudaya iitoni ezi-4, ngoko kufuneka songeze i-1000 milliliters ye-glacial acetic acid ukulungisa ixabiso le-pH phakathi kwe-4-6.

Olu hlengahlengiso lunokusinceda sizinzise ukuzinza kwedayi kumlinganiselo omkhulu, kwaye siphephe ingxaki yokubhidanisa umbala xa sishicilela. Kodwa kwiminyaka yakutshanje, uphuhliso lweshishini lokuprinta kunye nokudaya luncanyathiselwe ukubaluleka okukhulu ngurhulumente kunye neshishini lelaphu, kwaye inguqu yetekhnoloji yoshicilelo kunye neshishini lokudaya ibandakanyiwe kwelinye lamashishini aphambili enkxaso yoshishino lwelaphu. , ngoko iindlela zokudaya zoshishino ziye zaphuculwa kakhulu, ndiyakholwa ukuba kunye nophuhliso lwenzululwazi kunye nokuphuculwa okuqhubekayo, Ngokuqinisekileyo sinokusebenzisa iindlela zenzululwazi ukoyisa ishishini lokushicilela kunye nokudaya kunzima ukusombulula ingxaki yexabiso le-pH.

Kuyaziwa ukuba ngoku, siye sasebenzisa iindlela zenzululwazi ukuvela itekhnoloji yale mihla ye-elektroniki kunye ne-automation technology, i-biotechnology kunye nobunye ubuchwephesha obuphezulu njengeendlela zokuprinta kunye neshishini lokudaya. Ubuchwephesha bokushicilela obungenamanzi okanye obungenamanzi, obufana nokuprintwa kwe-micro-suspension, ukuprintwa kokudluliselwa kunye nokuprintwa kwedijithali, eziqhelekileyo kwimveliso, ziye zakhawuleza kakhulu uphando kunye nophuhliso kunye nokuveliswa kwemveliso ye-ecological textiles kunye neempahla ezisebenzayo. Ubukhulu becala, ulawulo longcoliseko lweshishini lokuprinta kunye nokudaya, ukusuka ekupheleni konyango ukuya kumthombo wothintelo.

Kodwa ngokumalunga nendlela yamandulo yokuprinta kunye nokudaya kwilizwe lethu, inzululwazi yanamhlanje kunye neteknoloji yokuprinta kunye nokudaya ilahlekelwe ngumgaqo wokumisela indlela yamandulo, ukukhawuleza kombala okulungileyo, kunye neenzuzo zokungafihli. Kodwa sikholelwa ukuba kuphuhliso olukhawulezayo lwesayensi, siya kuboyisa obu bunzima, kwaye sifumane indlela elungileyo yokuprinta kunye nokudaya. Ukudibanisa iteknoloji yoshicilelo lwemveli kunye nokudaya kunye neteknoloji yoshicilelo kunye nokudaya, ukuthatha ingundoqo kunye nokuphelisa intlenge, ukufumana iindlela zobugcisa obuphambili, kunye nokufezekisa iziphumo eziphawulekayo zemizi-mveliso.

Oku namhlanje uXiaobian ukwabelana nawe malunga nolwazi olufanelekileyo lwe-acetic acid ye-glacial, ndiyathemba ukukunceda.
