Ithini i-methyl hydroxyyl ilungisiwe?

Imvelaphi kunye noshwankathelo

I-Telupelose Ether yi-Polymer esetyenziswe kakuhle ye-polymer eyenziwe nge-pollummer yendalo ngonyango lweekhemikhali. Emva kwemveliso ye-seluplose i-selly kunye neseluplose Acetate ngenkulungwane ye-19, ooShemistics baphuhlise uthotho lwezinto ezininzi zeselselose yeSelulose yeSelulose yeSelulose eqhotyoshelweyo, ebandakanya amacandelo amaninzi emizini. Imveliso ye-Selelose Ether efana ne-Sodium Carboxymethyl Selelose (CMC), i-Ethyl selselyl Ityhlople (i-ECDC), i-HETYL Hydroxropyl seluplopyl .

I-HYDROXYETHyl Methyl Selelose (MHPC) yi-odorb engenanto, engenaxabiso, enganetyhefu emhlophe enokuthi ichithwe emanzini abandayo ukwenza isisombululo se-viscous esibonakalayo. It has the characteristics of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, maintaining moisture and protecting colloid. Ngenxa yomphezulu womsebenzi osebenzayo wesisombululo esinamandla, inokusetyenziswa njengearhente yokukhusela i-colloidal, i-eulsifier kunye nokusasazeka. I-HYDROXYETHyl Methylcelcelgalose isisombululo esihle kwaye iarhente efanelekileyo yokugcina amanzi. Kuba i-hydroxyleleyl methylcelcelcelose iqulethe amaqela e-hydroxyyteshyl, inamandla amahle ahlekisayo, ukungazinzi okuhle kunye nokunganyangeki komjelo ngexesha lokugcina ixesha elide.

I-HYDROXYETHyl Methylcelcelcelse Ubushushu be-methylcelcelfulose buphakane kune-MC.

Ulwakhiwo

Inqaku

Iimpawu eziphambili ze-Hydroxyutheyl MethylcelceLcelose: Hemc) zezi:

1. Ukungasebenzi: ukunyibilika emanzini kunye nezinye izinyibilikisi zendalo. I-HMC inokuchithwa kumanzi abandayo. Uxinzelelo oluphezulu luphezulu lumiselwe kuphela nguVeksity. Ukunyibilikisa kuyahluka nge-viscosity. Ezantsi kokufakwa kwe-viscosity, kokukhona ukonakala.

2. Ukunganyangeki kwetyuwa: Iimveliso zeHMC aziseseli ze-ionic selsulose oonina kwaye azizinzile kwizisombululo ze-act okanye zikhona, kodwa zisenzo eziphilayo, kodwa zisenzo esiphezulu sinokubangela ukungcwatywa kunye nokuchama.

3. Umsebenzi womphezulu: Ngenxa yomsebenzi osebenzayo wesisombululo esinamandla, inokusetyenziswa njengearhente yokukhusela i-colloidal, i-eulssifier kunye nokusasazeka.

4. Ijeli ye-thermal: Xa isisombululo semveliso yeHMC sishushube kubushushu obuthile, iba yi-Opaque, i-Gels, ibuyela ikakhulu kwi-gesices, kodwa i-gestipt ye-gesied ixhomekeke kubo i-bibriments, i-picloves, i-elloids, i-eulsiber njl njl.

I-5. I-Metabolic Intertity kunye ne-odor ephantsi kunye nevumba elimnandi: I-HMC isetyenziswa ngokubanzi ekutyeni neyeza kuba ayiyi kuba yi-metabolled kwaye inevumba eliphantsi kunye nevumba eliphantsi.

6. Ukunganyangeki kwe-mpuildew: i-HMC ichaze kakuhle kunye nokuzinza okuhle ngexesha lokugcina ixesha elide.

7. Uzinzo lwePH

Isicelo

I-Hydroxyyl Methylcelcelcelsulose inokusetyenziswa njengearhente yokukhusela i-colloidal, i-eulsifier kwaye isasazeke ngenxa yomsebenzi wayo osebenzayo kwisisombululo esinamandla. Imizekelo yayo yokwenza isicelo imi ngolu hlobo lulandelayo:

1. Isiphumo se-hydroxyyky I-Hydroxylceyl methylcelcelcelose yi-odorting yi-odolst, engenaxabiso, engabinayo ityhefu enokuchithwa emanzini abandayo ukwenza isisombululo se-viscous esibonakalayo. It has the characteristics of thickening, binding, dispersing, emulsifying, film-forming, suspending, adsorbing, gelling, surface active, maintaining moisture and protecting colloid. Kuba isisombululo se-ACTEACE sinomsebenzi obonakalayo ophucukileyo, inokusetyenziswa njengearhente yokukhusela i-colloidal, i-eulsifier kwaye isasazeke. I-HYDROXYETHyl Methylcelcelgalose isisombululo esihle kwaye iarhente efanelekileyo yokugcina amanzi.

2. Ipeyinti yokunceda eguquguqukayo kakhulu ilungisiwe, eyenziwe ngezixhobo ezilandelayo ezilandelayo kwiindawo ezinobunzima: 150-200 g yamanzi e-deeer I-60-700 g ye-emullion ecocekileyo; I-550-650 g ye-calcium enzima; I-70-90 g ye-Talcum powder; Isiseko isisombululo se-selselose ye-ITLEAG 30-30g; I-Lignocellose isisombululo se-10-20G; Uncedo lokwenza ifilimu 4-6G; i-antiseptic kunye ne-fungificide 1.5-2.5g; ukusasazeka 1.8-2.2g; iarhente emanzi 1.8-2.2g; 3.5-4.5G; Ethylene Glycol 9-11g; I-hydroxyleleeteyl methylcelcelcelse isisombululo senziwe ngokunyibilikisa 2-4% ye-hydroxyleleyl methylcelcelcelcelcelgalose emanzini; Isisombululo se-lignocelsulose senziwe nge-1-3% i-lignocelulose yenziwa ngokunyibilika emanzini.

Ukulungiselela

Indlela yokulungiselela i-hydroxythl methyl sethyl seluplose, le ndlela yile ndlela yokucoca i-cotton isetyenziswa njengezixhobo ezifunekileyo, kwaye i-i-ithylene oxide isetyenziswa njenge-arhente ye-e-Elethylse. Iinxalenye ezinobunzima bezixhobo eziluhlaza zokulungiselela i-Hydroxylcellyl Methylcelolce ngolu hlobo lulandelayo: iinxalenye ze-accetic acid; amanyathelo athile:

Inyathelo lokuqala, kwi-ketete ye-ketete, yongeza i-tolue kunye nomxube we-Isopropanol, kunye neSodium Hydroxide, ubushushu besiya kuthi ga kwi-60-80 ° C, qhubeka ufudumele imizuzu engama-20 ukuya kwengama-40;

Inqanaba lesibini, i-alkalition: Phola le nto ingentla ukuya kwi-30-50 ° C, yongeza i-cotton ye-Infork, kunye ne-Alkality Guqula i-3 ° CATRANE, kwaye i-APKROPAGOL MANDS i-3 ° C;

Inyathelo lesithathu: Isivumelwano: Emva kokuba i-alkalization igqityiwe, i-reactor ikhutshwe kwi-0.05-0.07.07MPA, kunye ne-ithylene oxide kunye ne-methyl chloride yongezwa imizuzu engama-30-50; Inqanaba lokuqala lokuthengiswa: 40-60 ° C, 1.0-2.0 iiyure, uxinzelelo lulawulwa phakathi kwe-0.15 ne-0.3mpa; Inqanaba lesibini le-Etherheli: 60 ~ 90 ℃, 2.0 ~ iiyure eziyi-2.5, uxinzelelo lulawulwa phakathi kwe-0.4 ne-0,8mpa;

Inqanaba lesine, ukungathathi cala: Yongeza i-aceid ye-acceting ye-GOCE kwangaphambili kwi-ketele, cinezela kwi-72 ° C yokuba kube yi-62 ° C ukuba ibe yintsimbi yesi-6 ngentsimbi yesi-8, i-ovelolting igqityiwe; Itanki yokuthintela i-develolvenution izaliswe ngamanzi e-PAPURE ephathwe nge-OSmois ye-OSmois kwi-90 ° C ukuya kwi-100 ° C;

Inyathelo lesihlanu, ukuhlamba kwe-centrifugal: Izinto ezikwinqanaba lesine lifakwe kwi-Centrifuge ethembekileyo, kwaye izinto ezahluliweyo zitshintshelwe kwitanki yokuhlamba ephethwe ngamanzi ashushu ngaphambi kokuhlamba umxholo;

Inyathelo lesithandathu, i-Centrifugal yomisa: Izinto ezihlanjwe zidluliselwa kwi-certififul ye-screyitifu, kwaye loo nto yomiswa nge-150-16 ° C, kwaye izinto ezomileyo zityunyuzwe kwaye zipakishwe.

Xa kuthelekiswa neTekhnoloji ye-EERMUSE ye-OERUSEE, i-Inglone yangoku isebenzisa i-E-Inglone Axide njenge-Arhente yokulungiselela i-Hydroxyl Methyl Sellyl Guiling Amaqela e-hydroxyyl. Inozinzo oluhle lozinzo kunye nokuxhathisa i-therdew ngexesha lokugcina ixesha elide. Ingasetyenziswa endaweni yokunye iiselwase.
