5. I-Synthesis ammonia: Ikwimo ye-cuprammonia acetate, esetyenziswa ekusulungekiseni i-syngas ukususa i-litl CO kunye ne-CO2
6. Ifoto: uMphuhlisi
7. Irabha yendalo: I-Coagulant
8. Ushishino lokwakha: Ukuthintela ikhonkrithi ekukhenkceni9. Kwi-addtin ikwasetyenziswa ngokubanzi kunyango lwamanzi, i-syntheticfiber, i-pesticides, iiplastiki, ufele, ipeyinti, ukusetyenzwa kwesinyithi kunye neshishini lerubha.
Abantu abaninzi abazi ukuba yintoni ukuprinta kunye nokudaya, ukuprinta kunye nokudaya kukwabizwa ngokuba ngukudaya kunye nokugqiba, luhlobo lwendlela yokulungiswa kwangaphambili kwelaphu, ngakumbi ekusebenziseni kwethu imihla ngemihla yokushicilela ilaphu. Kwinkqubo yokushicilela kunye nokudaya, ngokuqhelekileyo sisebenzisa iviniga yomkhenkce. Ke yintoni i-iced iviniga? Iviniga ye-iced eyaziwa ngokuba yi-acetic acid, eyaziwa ngokuba yi-acetic acid, i-organic monic acid, iyona nto iphambili yokusetyenziswa kweviniga yemihla ngemihla. Kwiqondo lobushushu begumbi, indawo yokukhenkceza yi-16.6 ° C, kwaye iya kuba yikristale engenambala emva kokuqina.
Ngoko kutheni sisebenzisa i-acetic acid ye-glacial kwinkqubo yokushicilela kunye nokudaya? Kutheni ukuprinta kunye nokudaya kusebenzisa i-acetic acid yeglacial? Kutheni ukongeza i-glacial acetic acid kwinkqubo yokuprinta kunye nokudaya? Oku kungenxa yokuba xa siprinta kunye nokudaya, ixabiso le-pH le-polyester yedayi yokusabalalisa kufuneka ibe phakathi kwe-4-6, ngoko xa ulungelelanisa idayi, kuyimfuneko ukusebenzisa i-glacial acetic acid ukuhlambulula, umzekelo, xa siprinta kunye nokudaya. , amanzi afunekayo ukudaya iitoni ezi-4, ngoko kufuneka songeze i-1000 milliliters ye-glacial acetic acid ukulungisa ixabiso le-pH kwi-4-6.
Olu hlengahlengiso lunokusinceda sizinzise ukuzinza kwedayi ngomlinganiselo omkhulu size siphephe ingxaki yokubhidanisa umbala xa sishicilela. Nangona kunjalo, kwiminyaka yakutshanje, uphuhliso lweshishini lokuprinta kunye nokudaya laseTshayina luxatyiswe kakhulu ngurhulumente kunye neshishini lelaphu, kwaye urhulumente uquke ukuguqulwa kobugcisa bokushicilela kunye neshishini lokudaya kwelinye lamashishini aphambili axhaswa yi-textile. ishishini, ngoko indlela yokudaya kushishino loshicilelo nokudaya iye yaphuculwa kakhulu, ndiyakholwa ukuba ukuphuculwa okuqhubekayo kophuhliso lwezenzululwazi, Kufuneka sikwazi ukusebenzisa iindlela zenzululwazi ukoyisa ishishini loshicilelo nokudaya nzima ukusombulula ingxaki ixabiso pH. .
Kuyaziwa ukuba okwangoku, sisebenzise iindlela zesayensi ukuvela itekhnoloji ye-elektroniki yale mihla kunye netekhnoloji ye-automation, i-biotechnology kunye nolunye ushishino oluphezulu lokuprinta kunye nokudaya. Ubuchwephesha obungenamanzi okanye obungenawo amanzi kunye nokudaya ubuchwephesha obufana nokuprintwa kwe-micro-suspension, ukuprintwa kokudluliselwa, kunye nokuprintwa kwedijithali, ezixhaphake kakhulu kwimveliso, ziye zakhawulezisa kakhulu ukusebenza kakuhle kophando kunye nophuhliso kunye nokuveliswa kweempahla zendalo kunye neempahla ezisebenzayo. Ukuya kumlinganiselo omkhulu, uthintelo longcoliseko kunye nolawulo lweshishini lokuprinta kunye nokudaya luye lwaphunyezwa, kwaye ukuguqulwa ukusuka kunyango lokugqibela ukuya kuthintelo lomthombo luphunyeziwe.
Nangona kunjalo, xa kuthelekiswa neendlela zakudala zokushicilela kunye nokudaya e-China, inzululwazi yanamhlanje kunye neteknoloji yokushicilela kunye nokudaya ayinayo umgaqo wokumisela indlela yamandulo, iingenelo zokukhawuleza kombala okulungileyo kwaye akukho lula ukucima. Kodwa sikholelwa ukuba ngokukhula ngokukhawuleza kwenzululwazi, ekugqibeleni siya kuboyisa obu bunzima size sifumane ezona ndlela zibalaseleyo zokushicilela nezokudaya. Ukudibanisa ushicilelo lwemveli kunye nobuchwephesha bokudaya kunye nobuchwephesha bokuprinta kunye nokudaya, ukuthatha isiseko kunye nokuphelisa inkunkuma, ukufumana eyona ndlela iphambili yezobugcisa kunye nokuphumeza ezona ziphumo zibalaseleyo zoshishino.
