Amanqaku olwazi malunga ne-hydroxyteethyl seluplose (hec ka-900-62-0)

Umlinganiswa:I-HYDROXYETYL Selelise (Hec Bas: 9004-62-0) yi-white okanye i-odolf engalunganga, engenakuthelene, kwaye ihamba ngokulula umgubo. Ukunyibilika kuwo omabini amanzi abandayo kunye namanzi ashushu, kodwa ngokubanzi i-insullen kwizinyibilikisi eziphilayo. Ixabiso le-pH litshintsha kancinci kuluhlu lwe-2-12, kodwa i-viscosity ihla ngaphezu kolu luhlu.

Ixabiso:I-HYDROXYETYL Selelise (Hec Bas: 9004-62-0) yi-tickener esetyenziswayo esetyenziswayo kwi-Insus esekwe emanzini ase-Seler. Yindawo eqingqiweyo yamanzi enamandla angenamanzi anezakhono ezilungileyo zamanzi, zinokuhlanjwa yi-oxygen, i-acids, kunye nee-enzymes, kwaye zinokuwela nge-CU2 + phantsi kweemeko ze-ALKALIIN. Ihlala izinzile, ayibonakali ijeli ngexesha lokufudumeza, ayizikhethi phantsi kweemeko ze-acidic, kwaye inepropathi efanelekileyo yefilimu. Isisombululo se-AICTO esikhuthazayo sinokwenziwa kwiifilimu ezibonakalayo, ezinokuthi zenziwa ngesenzo se-alkaline seseli ye-alkaline kunye neekhephethi ze-scowylene oxide, kwaye sinemilinganiselo yokutsala, ukhuseleko lokufuma, kunye nokhuseleko lokhuseleko lwefilimu. Indima ye-thiskeiners kwii-inki ezisekwe emanzini kukuzibandakanywa. Ukongeza i-thisfu kwi-inki kuyonyusa i-viscofity yayo, enokuphucula uzinzo lomzimba kunye neekhemikhali kwe-inki; Ngenxa yokwanda kwe-viscofity, i-raduology ye-inki inokulawulwa ngexesha lokuprinta; I-pigment kunye ne-filler kwi-inki akukho lula ukuba iphazamise, yandisa ukusetyenziswa kozinzo kwi-inki esekwe emanzini.

Indlela yemveliso: I-Alkali Selelose yi-polymer yendalo equkethe amaqela amathathu e-hydroxyl kwi-fibre iringi yesiseko. Elona qela lisebenzayo le-hydroxyl projeks ukuvelisa i-hydroxyEsethl sellulose. Thoba i-cotton ye-cotton yekotoni okanye i-pulp ehlaziyiweyo kwi-30% i-alkali, kwaye uyikhuphe ukuze ucinezele emva kwesiqingatha seyure. Cinezela kude kube ngumxholo wamanzi alkaline ufikelela kwi-1: 2.8, kwaye emva koko uyityumze. I-alkali i-alkali ifakwe kwireferensi, etywiniweyo, igonyiwe, yazaliswa yi-nitrogen. Incwadana yekhemikhali ephindaphindwe iphungulwe kwaye izaliswe yi-nitrogen yokutshintsha yonke umoya kwindawo yokuphendula. Cinezela kwi-Looylene ye-Oxide oXide, udlule amanzi okupholisa kwi-jacket, kwaye ulawule ubushushu bokuphendula malunga ne-25 ℃ ukufumana imveliso ye-hydroxyyl yellroxyyl ye-cleudethyl ye-cleudethyl ye-cleudethyl selly. Imveliso e-CROD ihlanjululwe ngotywala, inamacala nge-acetic acid ukuya kwi-PH 4-6, kwaye inxibelelene neGlyoxal yokwaluphala. Emva koko hlamba ngamanzi, iCentrifuge, ihydibe, eyomileyo, kwaye igalele i-hydroxyythyl sellyulose.
