4 Su'aalood oo ku saabsan HPMC

1. Waa maxay isticmaalka ugu muhiimsan ee hydroxypropyl methylcellulose (HPMC)?
HPMC waxaa si weyn loogu isticmaalaa agabka dhismaha, dahaarka, xabagta synthetic, ceramics, farmashiyaha, cuntada, dharka, beeraha, isqurxinta, tubaakada iyo warshadaha kale.HPMC waxa loo qaybin karaa darajada dhismaha, darajada cuntada iyo heerka dawooyinka iyadoo loo eegayo isticmaalkeeda.Waqtigan xaadirka ah, inta badan wax soo saarka gudaha Shiinaha ayaa ku jira heerka dhismaha.Heerka dhismaha, budada putty waxaa loo isticmaalaa tiro aad u badan, qiyaastii 90% budada shubka ah iyo tan kale ee sibidhka iyo xabagta dhoobada.

2. Maxay yihiin sababaha nabarrada budada ah ee budada ah inta lagu guda jiro codsiga HPMC ee budada putty?
HPMC waxay u shaqeysaa sidii dhumuc weyn, biyo celiya iyo wax ku dhisa budada suufka ah.Wax falcelin ah kuma jirto.

Sababaha nabarrada: 1. Biyo badan.2. Lakabka hoose ma aha mid engegan, kaliya ku xoq lakabka sare ee lakabka, kaas oo sidoo kale si fudud u finan.

HPMC

3. Immisa nooc oo ah hydroxypropyl methylcellulose (HPMC) ayaa jira?Waa maxay faraqa u dhexeeya?
HPMC waxa loo qaybin karaa mid degdeg ah iyo mid kulul.Alaabta milmi leh, si dhakhso ah u daa oo ku baaba'a biyaha biyo qabow.Halkaa marka ay marayso, dareeruhu ma laha viscosity maadaama HPMC ay si fudud ugu firirsan tahay biyaha oo aan milmin.Qiyaastii 2 daqiiqo ka dib, viscosity ee dareeraha ayaa si tartiib tartiib ah u kordhaya, samaynta jel viscos ah oo cad.Alaabta kulul ee milmi kara waxay si degdeg ah ugu firdhi kartaa biyaha kulul waxayna ku baaba'aysaa biyaha kulul.Marka heerkulku hoos ugu dhaco heerkul gaar ah, mawgu si tartiib tartiib ah ayuu u soo baxayaa ilaa laga sameeyo gel cad oo viscos ah.

Nooca dhalaalka kulul waxaa loo isticmaali karaa oo kaliya budada suufka ah iyo hoobiyeyaal.Xabagta dareeraha ah iyo rinjiyada, dubista ayaa dhacda lamana isticmaali karo.Nooca degdega ah wuxuu leeyahay codsiyo kala duwan oo kala duwan waxaana loo isticmaali karaa budada putty iyo hoobiyeyaal iyo sidoo kale xabagta dareeraha ah iyo rinjiga.

4. Sidee loo go'aamin karaa tayada hydroxypropyl methylcellulose (HPMC) si fudud iyo muuqaal?
(1) Cuf-jiidadka gaarka ah: Mar kasta oo cuf-jiidadka gaarka ah uu sareeyo, ayaa tayada sii wanaagsanaaneysa.
(2) Caddaan: Inta badan alaabooyinka tayada leh waxay leeyihiin caddaan wanaagsan.Marka laga reebo kuwa leh walxaha caddaynta lagu daray.Waxyaalaha caddaynaya waxay saamayn karaan tayada.
(3) Fineness: Markasta oo ay fiicnaato, ayaa tayada wanaagsan.Wanaagsanaanta HPMC-gayada badanaa waa 80 mesh iyo 100 mesh, 120 mesh sidoo kale waa la heli karaa.
(4) Gudbinta: Ku rid HPMC biyaha si aad u sameysid jel hufan una fiirso gudbintiisa.Inta badan gudbinta, walaxda aan la milmi karin ayaa sii yaraanaysa.Reactors vertical sida caadiga ah waxay leeyihiin gudbin ka fiican iyo reactors jiifsan ay leeyihiin gudbin liidata, laakiin tani macnaheedu maaha in tayada wax soo saarka ee reactors toosan ay ka fiican tahay hababka kale ee wax soo saarka.Waxaa jira arrimo badan oo go'aamiya tayada badeecada ee reactors jiifka ah, kuwaas oo leh maaddo hydroxypropyl sare leh iyo maaddo sare oo hydroxypropyl ah, taas oo ugu fiican xajinta biyaha.
