Codsiga iyo diyaarinta hydroxytylylylyl bylulel bycyl

Hydroxyetylytyl bylyl blulose hemcWaxaa loo isticmaali karaa inuu yahay wakiilka kahortagga coller, emulsifier iyo kala firidhsan sababtoo ah howsha dusha sare ee kacsan ee xalka aquous. Tusaalaha codsigiisa waa sida soo socota: Saamaynta ay ku leedahay hydroxytylylyl byluyl bylule oo ku saabsan guryaha sibidhka. Hydroxyetylylcellelrcellellase waa urxan, dhadhan la'aan, budo cad oo cad oo ku milmaysa biyo qabow si ay u sameeyaan xalka cad, viscous. Waxay leedahay astaamaha qarosiinta, xidhitaanka, kala firidhsan, emulsifideynta, sameynta filimka, oo la joojinayo, xaraashka, dusha sare, firfircoon, oo ah firfircooni, oo ilaalinaysa qoyaan iyo difaacida qoyaanka iyo ilaalinta codadka. Sababo la xiriira shaqada firfircoon ee tooska ah ee xalka aqueous, waxaa loo isticmaali karaa inay tahay wakiilka ka hortagga coller, emulsifier iyo kala firidhsan. Hydroxytylylylyl bluelose xalka aquolor wuxuu leeyahay hawo fiican oo uu yahay wakiil-ka-haynta biyaha-sare.
diyaarin
Qaab loo diyaariyo hydroxytylyl bylulel bylulose, habku wuxuu ka kooban yahay iyadoo la adeegsanayo suuf suuf ah oo ah shey ceyriin ah iyo ethylneneneene oksice ah si loo diyaariyohydroxytylylyl bylule. Alaabada ceyriinka ah ee loogu diyaariyo hydroxytylyl bylulose melulose waxaa loo diyaariyey qaybo miisaan ah: 700-800 qaybo ka mid ah isku dhafka toluene iyo isopropanol ahaan, 70-80 qaybood oo biyo ah oo ah sodium hydroxide, 80-85 qaybo ka mid ah oo lagu safeeyey suufka, 20-28 qaybood oo ka mid ah oksiyadaan, 80-90 qaybood oo ka mid ah methyl chloride, iyo 16-19 qaybood oo ka mid ah aashitada barafka ee glacial; Tallaabooyinka gaarka ah waa:

Tallaabada ugu horreysa, ka-faa'iideysta, ku dar isku dar ah isku dar ah iyo isopropropanol, biyo, iyo sodium hydroxide, kululaynta ilaa 60 ~ 80 ℃, la soosaaray 20 ~ 40 daqiiqo;

Tallaabada labaad, alantasization: Ku qabooji qalabka kor ku xusan illaa 30 ~ 50 ℃, ku dar suuf oo la safeeyey, ku buufiyo nitrogen-ka, oo ku beddelo nitrogen-ka 3 beddelaad ah, oo fuliso alkali ka dib markii la beddelo alantalization Shuruudaha waa sida soo socota: Waqtiga aleqalization waa 2 saacadood, iyo heerkulka alantasization waa 30 ° C illaa 50 ° C;

Tallaabada saddexaad, soo-saaris: alisiidhka ayaa la dhammeeyay, soo-saareyaasha ayaa loo daadgureeyay ilaa 0.05 ~ ~ 0.07Mpa, ethylineene oxide iyo methyl chloride-ka iyo methyl chloride-ka ayaa lagu daray, waxaana lagu hayaa 30 ~ 50 daqiiqo; Marxaladda koowaad ee xirashada: 40 ~ 60 ℃, 1.0 ~ 2.0 saac, cadaadiska ayaa la xakameynayaa inta u dhexeysa 0.150.3mpa; Marxaladda labaad ee xirashada: 60 ~ 90 ℃, 2.0 ~ 2.5 saacadood, cadaadiska ayaa la xakameynayaa inta u dhexeysa 0.40.8mpa;

Tallaabada 4-aad, dhex-saar: Ku dar aashitada aashitada barafka ah ee is-karka ah, kululee arinta ugu sareeya ee dhexdhexaad ah, kululeeyo 82 ~ si aad u sameyso roobab, heerkulka ayaa kor u kacaya 102 ℃℃ ph ph 68 Marka roobabku dhamaado, haanta roobka waxaa ka buuxa biyaha tuubada ee lagu daaweeyo aaladda osmosis-ka dib-u-soo-celinta ee 90 ℃ ℃;

Tallaabada shanaad, maydhista Centrifugal: Maaddadii tallaabada afraad waxay ku tilmaantaday centrifuge sentrifuge oo toosan, oo sheyga kala-baxa waxaa lagu wareejiyaa weelka lagu dhaqo ka buuxaan biyo kulul, iyo maaddada la maydhay;

Tallaabada lixaad, qalajinta Centrifugal: Waxyaabaha la maydhay ayaa loo qaadayaa qalajiyaha iyada oo loo marayo centrifeed centrifeed oo siman, maaddada waa la qalajiyaa 150-170 ° C, iyo maaddada la qalajiyey waa baara.

Marka la barbar dhigo jirachelther etherTeknolojiyadda wax soo saarka, soo-saarista soo-saarista oxide ee loo yaqaan 'ethyleneneeneeneene ovide' ee u diyaarinaya hyroxykylyl by byelyl, xasilloonida ugu sareeya maxaa yeelay, xasilloonida muuqaalka wanaagsan, iska caabbinta muuqaalka ah iyo kaydinta muddada-dheer. Waxaa loo isticmaali karaa halkii laga isticmaali lahaa wax kale oo keli ah ee keli ah ee keli ah.
