Dhisidda Fasalka MHEC

Xadhiga Dhismaha MHEC

Dhisidda fasalka MHEC Metyl hydroxytylCEllelosewaa ur, dhadhan la'aan, budo cad oo aan sun lahayn oo lagu kala diri karo biyo qabow si loo sameeyo xalka viscous transpare. Waxay leedahay astaamaha dhumucda, isku xidhka, kala-sooca, emulsification, abuurista filimka, eryida, xayiraad, dhaqdhaqaaqyo dusha sare, nashaadaadka dusha, haynta qoyaanka iyo isbadalka qoyaanka iyo difaaca qoyaan. Maaddaama xalka aqueous uu leeyahay hawsha sare ee firfircoon, waxaa loo istcimaali karaa sidii wakiil ilaalin ah oo kahortag ah, emulsifier iyo kala firidhsan. Dhismaha Fasalka MHEC methyl hydroxyElcellersose xalka aquophicicicase wuxuu leeyahay hawo-mareenka wanaagsan oo uu yahay wakiilka biyaha sii hufan. Kariimka hydroxytylyl bylulel waxaa ku jira kooxaha hydoxytyl, sidaa darteed waxay leedahay awood wanaagsan oo caaryada wanaagsan, xasilloonida muuqaalka muuqaalka iyo wax-hayeeya-infekshanka muddada-dheer ee kaydinta muddada-dheer.

Guryaha jirka iyo kiimikada:

Muuqashada: MHEC waa cad ama ku dhawaad ​​cad cad ama budo granular; ur la'aan.

Xoolaha: MHEC waxay ku milmi kartaa biyaha qabow iyo biyaha kulul, moodalka L waxay ku milmeyn kartaa biyo qabow, MHEC waa mid aan ku jirin inta badan dareeraha dabiiciga ah badankood. Daaweynta dusha sare, kala firidhsan MHEC biyo qabow iyada oo aan la helin ammaanta, oo si tartiib ah ayaa loogu kala diri karaa iyadoo la hagaajinayo qiimaha pH ee 8 ~ 10.

Isticmaal 

Xadhiga dhisidda MHEC methylyyl hydroxykyl byluleyl waxaa loo isticmaali karaa si loo ilaaliyo, emulsifier, emulsifier, emullus, emullrier iyo kala firidhsan oo kala firidhsan awgeed howsha firfircoon ee xalka ah ee aqueous. Tusaalooyinka codsiyadeedu waa sida soo socota:

1. Saamaynta methylhydydydydytresyylcellosuse ee waxqabadka sibidhka MHEC metylylhydellcellcellcellcellcellexylcellelcellelcellelcellelcellelcellosureyl, oo aan sun lahayn, oo aan lagu kala diri karin biyo qabow si loo sameeyo xalka viscous ee hufan. Waxay leedahay astaamaha dhumucda, isku xidhka, kala-sooca, emulsification, abuurista filimka, eryida, xayiraad, dhaqdhaqaaqyo dusha sare, nashaadaadka dusha, haynta qoyaanka iyo isbadalka qoyaanka iyo difaaca qoyaan. Maaddaama xalka aqueous uu leeyahay oo ah howlo firfircoon oo dusha sare ah, waxaa loo isticmaali karaa emulsifier, emulsifier iyo kala firidhsan.
2.

Sida loo soo saaroDhisidda Fasalka MHEC?

-Ga / -dawax soo saarHabka dhisidda fasalka MHEC methyl hydroxytyl ceyrta byluxyl waa cudbirkaas oo la safeeyey waxaa loo istcimaalaa sida shey ceyriin ah iyo ethylenenenenene-ka waxaa loo istcimaadaa wakiilka loo yaqaan 'Etherne-ka' si loo diyaariyo fasalka MHEC. Alaabada ceyriinka ah ee loogu talagalay diyaarinta fasalka MHEC waxaa loo diyaariyey qaybo culeys ah: 700-800 qaybo ka mid ah toluene iyo isopropanol isku dar ah oo ah xalka biyaha, 70-80 qaybood oo ah sodium hydroxide, 80-85 qaybo ka mid ah suufka la safeeyey, Wac 20-28 qaybo ka mid ah ok okkythane, 80-90 qaybood oo ka mid ah methyl chloride, 16-19 qaybood oo ka mid ah aashitada barafka ee glacial; Tallaabooyinka qaaska ah waa sida soo socota:

Tallaabada ugu horreysa, ku dar isku dhafka toluene iyo isopropanol, biyo, iyo sodium hydroxide ku shub kel-ka-celin celinta, kor ugu qaad heerkulka 60-80 ° C, oo ku hay 20-40 daqiiqo;

Tallaabada labaad, alantasization: Ku qabooji qalabka kor ku xusan illaa 30-50 ° C, oo ku dar suuf la safeeyey, oo ku buufiyo isku-darka toluene iyo isoprogen, oo aad u soo buuxiso nitrogen-ka 3 beddelaad ah, oo aad u fuliso alkalis ka dib marka lagu beddelo xaaladaha alkalin waa sida soo socota: Waqtiga alantalization waa 2 saacadood, iyo heerkulka alantasization waa 30 ℃-50 ℃;

Tallaabada saddexaad, xirashada: ka dib markii loo yaqaan 'alkalization', jawaabta ayaa loo daadgureeyay ilaa 0.05~0.0MPA, ethelineeene oxide iyo methyl chloride-ka ayaa lagu daray oo lagu hayaa 30~50 daqiiqo; Marxaladda koowaad ee xirashada: 40~60 ℃, 1.0~2.0 saacadood, cadaadiska ayaa la xakameynayaa inta u dhexeysa 0.15-0.3mpa; Marxaladda labaad ee xirashada: 60~90 ℃, 2.0~2.5 saacadood, cadaadiska ayaa la xakameeyaa inta udhaxeysa 0.4-0.8mpa;

Tallaabada afraad, dhex-beelka: Ku dar aashitada barafka ee dareeraha ah ee loo yaqaan 'Spetlvel acid', riix agabka ether-ka ee dhexdhexaadnimada, kor u qaad heerkulka illaa 75~80 ℃ oo lagu khaldan yahay, heerkulku wuxuu u kici doonaa 102 ℃, qiimaha pH wuxuu noqon doonaa 68. Markuu gaabadu dhammaado; Buuxi khatarta dagaaleyda biyaha tuubada ah ee lagu daaweeyo aaladda osmosis-ka ee loo yaqaan 'osmosis' ee 90 ℃~100 ℃;

Tallaabada shanaad, dhalka Centerrifaatugal: Qalabka talaabada afraad waa Centrifuge by centrifuge by centrifeed daboolka toosan ee toosan, iyo agabyada kala go 'waxaa lagu wareejiyaa weelka lagu dhaqo oo ka buuxo biyo kulul.

Tallaabada lixaad, qalajinta Centrifugal: Qalabka la maydhay ayaa loo qaadaa qalajiyaha iyada oo loo marayo centrifeed centrifeed oo toosan, agabku waa la qallajiyaa 150-170 ° C, iyo agabyada qalalan waa la burburiyey oo xirxiran.

Marka la barbar dhigo tikniyoolajiyadda soosaarka ee ether ee jira, haddaHabka wax soo saarkaWuxuu adeegsadaa ethyleneeene ovide oo ah wakiilka ugu sarreeya si loo diyaariyo fasalka MHEC methroxyylyl hydroxyetyl ​​byluxyll, oo sababta oo ah waxaa ku jira kooxaha hydroxytyl, waxay leedahay awood ka hortal fiican. Deganaanshaha Muuqaalka Muuqaalka Fiican iyo Caabbitaanka Cabsida ee Wanaagsan Inta lagu jiro kaydinta muddada-dheer. Waxay beddeli kartaa kuwa kale ee keli ah ee keli ah ee keli ah.

BU eedeynta fasalka MHECwaa unugyada loo yaqaan 'cellosol ether',Cell chether waa shey polymer shey kiimiko ah oo leh noocyo fara badan oo ay ka samaysan tahay unugyada polymer ee dabiiciga ah iyada oo loo marayo daaweynta kiimikada. Maaddaama cudurka cellulose iyo unugyada cellulose ay la sameeyay qarnigii 19aad, farmashiistayaashu waxay soo saareen taxane badan oo isdaba joog ah oo ka mid ah anshaxa unugyada unugyada. Meelaha cusub ee arjiga ayaa si joogto ah loo ogaanayaa isla markaana waaxyo badan oo warshadeed ayaa ku lug leh. Cell Sylules Ether Stats sida Sodium Carborborykyl Cell (CMC), Hydroxytyl (HECCylyProsel (MHCYLYL Hydroxyl (MHPYL Hydroxylfyl (MHPCY Pladroxylfyphyl (MHPC) iyo anshaxa kale ee keli ah ayaa loo yaqaan "" Monosodium Monosodium Glutamate "iyo Darajada Darajada MHEC waxaa si weyn loogu isticmaalay dhagxaanta dhagaxa, hoobiye qalalan, sibidhka iyo balaastigga gypsum iwm.
