Hydroxypropyl methylcelrellose, shahaadadan ma qoomameyn doonto!

1. HPMC waxay u qaybsan tahay nooca deg-degga ah iyo nooca dheeraadka ah ee kala-guurka

HPMC FIVID FIVID FIVENTHE Cloff S Hemrix, geedi socodka wax soo saarka, si loogu daro daaweynta gorlox.

Nooca degdegga ah ee HPMC kuma daro wax waraaqo ah, sida "100000" waa "100000 peaces si dhakhso leh oo kala firidhsan HPMC".

2. Iyada oo leh ama aan lahayn s, astaamo kala duwan

Ku soo dhaqso soonka HPMC, oo biyo qabow ah si dhakhso leh u kala firdhiyey, oo lagu waayey biyaha, maxaa yeelay HPMC ayaa ah mid ka dib ah, oo ku saabsan aragtida dareeraha ayaa si tartiib tartiib ah u noqota, sameysashada viscous viscous viscous.

Degdeg ah HPMC, si dhakhso ah ayaa loogu kala firdhiyaa biyo kulul ilaa 70 ℃, in lagu tuuro heerkul gaar ah, viscobar si tartiib ah ayuu u muuqdaa, ilaa samaynta viscouid viscous viscous.

3. Iyada oo leh ama aan lahayn s, adeegsi kala duwan

Isla markiiba HPMC waxaa loo isticmaali karaa oo keliya budada iyo hoobiyeynta, madaafiicda, ku jira xabagta dareeraha ah iyo rinjiga iyo dharka lagu dhaqo, waxaa jiri doona ifafaale kooxeed, lama isticmaali karo.

Soosaarka degdega ah ee HPMC, tirada dalabka ayaa aad u ballaaran, budada ah, hoobiye, hoobiye, xabagta dareeraha ah, rinjiga, maydhista saadka lagu dhaqdo waa la isticmaali karaa, majiro wax tabo ah.

Habka Kala-baxa

1. Qaado qaddarka loo baahan yahay ee biyaha kulul oo kululee ilaa 80 ℃ ama kolka ka sareeya weelka. Ku dar badeecadan si tartiib tartiib ah u hooseeyso kareyso gaabis ah.

2, ama kuleylka 1/3 ama 2/3 biyaha kulul ilaa in ka badan 85 ℃, ku dar cellulose, qaado sturry biyo kulul, ka dibna ku dar kareyso biyaha qabow, qaboojinta, qaboojinta isku dar ah ayaa la sameeyay.

3, tirada mesh-ka-buugga ayaa fiican, budada isku-darka ah waa qayb yar oo yar, ka dib marka biyaha si dhakhso ah loo kala diro, samaynta viscosity loo baahan yahay.

4. Si tartiib ah ugu dar cellulose si tartiib tartiib ah oo siman heerkulka qolka, si isdaba joog ah uga walaaq hawsha ilaa xalka daah furnaanta la sameeyo.

Waa maxay arrimaha saameeya haynta biyaha ee biyo-baxa hydroxypropyl bylule?

Hydroxypropylkyl methylcelrelose HPMC Waxyeelada laftooda ayaa inta badan saameyn ku leh qodobbada soo socda:

1. HPMC Hormgene of cell ether

HPMC Finjirosiinta yunifoomka, ee Methoxy, qaybinta labiska biyaha ee hydroxypropoxy, heerka biyo haynta ee biyaha.

2. Cilmiga unugyada Chert hpmc hbel kulul

Jel kulul wuxuu leeyahay kuleyl aad u sarreeya iyo heerka biyo-haynta biyaha sare. Taa baddalkeeda, heerka haynta biyaha ayaa hooseysa.

3. HPMC VOMBCOSIOSKA CELETOS

Markii qaboojinta ee HPMC ay kordho, heerka haynta biyaha ayaa sidoo kale kordha. Marka muuqaalku gaaro shahaado gaar ah, kororka heerka haynta biyaha wuxuu u muuqdaa mid siman.

Qaddarka cellulose ether hpmc ayaa lagu daray

Qaddarka badan ee unugyada cellulose ether HPMC ayaa ku dartay, heerka sare ee biyaha sare, ayaa sifiican u saameeya biyaha haynta biyaha.

Inta u dhexeysa 0.25-0.6%, heerka haynta biyaha ayaa si dhakhso leh kor ugu kacaya kororka qaddarka dheeriga ah. Kordhinta isbeddelka heerka keydka biyaha ayaa hoos u dhacay marka lacagta lagu kordhin lahaa.
