Nguwuphi umahluko phakathi kwe-hydroxypropyl methyl seluplose ne methyl sellie?

1.(I-HPMC) impahla yomzimba kunye neekhemikhali:

I-1. Imbonakalo: mc imhlophe okanye i-fibrous emhlophe okanye i-graneul yomgubo, engenakuphela.

2. Iipropathi: I-MC iphantse ingenanto i-eshanol epheleleyo, i-ether ne-acetone. Isasaza ngokukhawuleza kwaye idumbe amanzi ashushu nge-80 ~ 90 ° C, kwaye inyibilike ngokukhawuleza emva kokupholisa. Isisombululo se-ACTEACE sizinzile kubushushu begumbi, kwaye sinokugeza kubushushu obuphezulu, kwaye ijeli inokutshintsha ngesisombululo kunye neqondo lobushushu. Inenkohliso egqwesileyo, ukusasazeka, ukunamathela, ukuqaqanjelwa, ukwenziwa, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu, kunye nokungafezeki kweoyile. Ifilimu eyenziweyo inobunzima obuhle, bhetyebhetye kwaye bungafihli. Kuba ayihambelani nenye i-ionic, inokuhambelana nezinye ii-EMulssifiers, kodwa kulula ukuthunyelwa ityiwa, kwaye isisombululo sizinzile ngaphakathi kwi-PH2-12.

I-3. Ukubonakala kokuxinana: 0.30-0.70G / CM³, uxinzelelo malunga ne-1.3G / CM³.

I-2. Indlela yokuchitha:

Xa iimveliso ze-MC zongezwa ngokuthe ngqo emanzini, ziya kudibanisa, kodwa ukuchithwa kucotha kakhulu kwaye kunzima. Zintathu iindlela zokuchitha ixesha eliphakanyisiweyo apha ngezantsi, kwaye abasebenzisi banokukhetha eyona ndlela ifanelekileyo ngokomsebenzi wabo:

1. Indlela eshushu yamanzi: Kuba i-MC ayinyibiliki emanzini ashushu, i-MC ingasasazeka kakhulu emanzini okuqala, kwaye emva koko xa ipholile, iindlela ezimbini eziqhelekileyo zichazwe ngolu hlobo lulandelayo:

1). Beka inani elifunekayo lamanzi ashushu kwisitya kwaye asitshise malunga nama-70 ° C. I-MC iyongezwa ngokuthe ngcembe phantsi kokukhulisa kancinci, ekuqaleni i-MC inyibilikile kumphezulu wamanzi, emva koko yazenzela ngokuthe ngcembe isilayidi, nto leyo eyayipholile.

2). Yongeza i-1/3 okanye i-2/3 yexabiso elifunekayo lamanzi kwisitya, kwaye sitshise ukuya kwi-70 ° C. Ngokwendlela ye-1), ukusasaza i-MC ukulungiselela ukulungisa amanzi ashushu; Emva koko yongeza inani eliseleyo lamanzi abandayo okanye amanzi omkhenkce ukuya kwi-slingry yamanzi ashushu, umxube wapholwa emva kokuvuselela.

2. Indlela yokuxuba iPowder: MC Powders amasuntswana kunye nesixa esilinganayo okanye esikhulu sezinye izithako ezilinganayo zisasazeke ngokupheleleyo, kwaye emva koko ichithwe emanzini, i-MC inokuchithwa ngeli xesha ngaphandle kwe-agegrammeration.

I-3. I-Organic Soltion Indlela: Ukusasazeka kwangaphambili okanye ukusasazeka kwangaphambili i-MC ngeenyibilikisi, ezinjenge-ethanol, i-etlone Glycol, i-oyile, kwaye yongeza amanzi ngokutyibilikwa kakuhle ngeli xesha.

3. Sebenzisa:

Le mveliso isetyenziswa ngokubanzi ekwakhiweni, izinto zokwakha, iingubo ezisasazayo, i-Polymerization yePhezulu, i-Tricker, i-Gicker kunye ne-Ginser, njl. Njl. I-tickener kwishishini elihlekisayo, kwaye isetyenziswa ngokubanzi kwi-petroleum yokuqhuba nemizi-mveliso yemichiza yemihla ngemihla.

I-Methylcelculose (MC) ye-MC kunye neekhemikhali:

I-1. Imbonakalo: mc imhlophe okanye i-fibrous emhlophe okanye i-graneul yomgubo, engenakuphela.

2. Iipropathi: I-MC iphantse ingenanto i-eshanol epheleleyo, i-ether ne-acetone. Ukusasazeka ngokukhawuleza kunye nokuntywila emanzini ashushu nge-80 ~ 90> ℃, kwaye inyibilike ngokukhawuleza emva kokupholisa. Isisombululo se-ACTEACE sizinzile kubushushu begumbi, kwaye sinokugeza kubushushu obuphezulu, kwaye ijeli inokutshintsha ngesisombululo kunye neqondo lobushushu. Inenkohliso egqwesileyo, ukusasazeka, ukunamathela, ukuqaqanjelwa, ukwenziwa, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye neempawu zokwenza ifilimu, kunye nokungafezeki kweoyile. Ifilimu eyenziweyo inobunzima obuhle, bhetyebhetye kwaye bungafihli. Kuba ayihambelani nenye i-ionic, inokuhambelana nezinye ii-EMulssifiers, kodwa kulula ukuthunyelwa ityiwa, kwaye isisombululo sizinzile ngaphakathi kwi-PH2-12.

I-3. Ukubonakala kokuxinana: 0.30-0.70G / CM³, uxinzelelo malunga ne-1.3G / CM³.

4. Indlela yokuphelisa

I-MC> Xa imveliso yongezwa ngokuthe ngqo emanzini, iya kudibanisa, kodwa ukuchithwa kucotha kakhulu kwaye kunzima. Zintathu iindlela zokuchitha ixesha eliphakanyisiweyo apha ngezantsi, kwaye abasebenzisi banokukhetha eyona ndlela ifanelekileyo ngokomsebenzi wabo:
