1. Waa maxay dalabka ugu weyn ee loo adeegsado hydroxypropyl methylcelrelosuse (HPMC)?
HPMC waxaa si weyn loogu adeegsadaa qalabka dhismaha, jaakadaha, isugeynta isku-darka, dhoobada, dawada, cuntada, dharka, waxyaabaha la isku qurxiyo, tubaakada iyo warshadaha kale. HPMC waxaa loo qaybin karaa fasalka dhismaha, heerka cuntada iyo darajada dawooyinka sida ku xusan ujeedadaas. Waqtigan xaadirka ah, inta badan waxyaabaha gudaha badankood waa fasalka dhismaha. Fasalka dhismaha, budada loo yaqaan 'perodty budada loo isticmaalo tiro badan, qiyaastii 90% waxaa loo isticmaalaa budada wareega, inta kalena waxaa loo isticmaalaa hoolkan.
2. Waa maxay urta urta hydroxypropyl methylcelrellase (HPMC)?
HPMC waxaa soo saaray habka solvent adeegsiga toluene iyo isopropanol inay yihiin solvents. Haddii maydhistu aysan aad u fiicneyn, waxaa jiri doona ur hadha.
3. Waa maxay hababka kala dirida ee hydroxypropyl methylcelrellase (HPMC)?
Habka Kala-goynta biyaha kulul Laba habab oo caadi ah ayaa lagu sifeeyay sida soo socota:
1) Dhex dhig qaddarka loo baahan yahay ee biyaha kulul weelka oo kululee ilaa 70 ° C. Hydroxypropylykylcellellase methylcelrelolose waxaa si tartiib tartiib ah loogu daray kareyso gaabis ah, markii hore HPMC dusha sare ee biyaha, ka dibna si tartiib tartiib ah ayaa loo sameeyay slurry, oo lagu qaboojiyey.
2), ku dar 1/3 ama 2/3 ee biyaha ee loo baahan yahay weelka, oo kululeeyaa 70 ° C, kala firdhin si waafaqsan habka 1), oo u diyaari biyo jilicsan; Ka dib ku dar qaddarka haray ee biyaha qabow si aad u jilicsan tahay biyaha kulul, isku dar ah ayaa la qaboojiyey ka dib markii uu karey kareemay.
Qaabka budada ah Budada budada ah iyo soosaaraha hoobiyeyaasha ayaa adeegsanaya qaabkan. [Hydroxypropyl methylrcellellase (HPMC) waxaa loo isticmaalaa inuu yahay wakiilka xajiska iyo biyaha ee madaafiicda budada ah. ]
4. Sideed u xukumaan tayada tayada hydroxypropyl methylrcellellase (HPMC) si fudud iyo si heer sare ah?
(1) Cunnadaha: In kasta oo cadaanku uusan go'aan ka gaari karin in HPMC ay fududahay in la isticmaalo, iyo haddii wakiilo caddaan ah lagu daro inta lagu gudajiro nidaamka wax soo saarka, waxay saameyn ku yeelan doontaa tayadeeda. Si kastaba ha noqotee, inta badan waxyaabaha wanaagsan ee wanaagsan waxay leeyihiin cadaan wanaagsan.
(2) Filinka: Liqiitii HPMC guud ahaan waxay leedahay 80 mesh iyo 100 mesh, iyo 120 mesh ayaa ka yar. Inta badan HPMC waxaa laga soo saaray ku yaal Hebei waa 80 mesh. Finalka wanaagsan, guud ahaan hadalka, ayaa ka fiican.
(3) TrafMaal Gardhanka Tartanka weyn ee iftiinka, ayaa ka fiican, muujinaya in ay jiraan wax yar oo ka yar in ka yar. . Quruxda badan ee dib-u-soo-celinta toosan waa mid wanaagsan, iyo in dib-u-helaha toosan ay ka sii darayaan, laakiin micnaheedu maahan in tayada dib-u-celinta tooska ahi ay ka fiican tahay tan dib-u-helka toosan, iyo tayada wax soo saarka waxaa go'aamiya arrimo badan.
(4) culeys gaar ah: culayska weyn ee culeyska gaarka ah, oo si fiican u sii culus. Tayo-siinta waa weyn tahay, guud ahaan maxaa yeelay nuxurka ku jira hydroxypropyl waa sarreysaa, oo nuxurka ku jira kooxda hyroxypropyl kooxda ayaa kacsan, haynta biyaha ayaa ka fiican.
5. Waa maxay farqiga u dhexeeya nooca biyaha-qabow iyo nooca kulul ee kululaynta hydroxypropyl methylcelrelosuse ee nidaamka wax soo saarka?
Nooca degdega ah ee HPMC-ga ayaa dusha sare ku daaweyneysa gelwal, waxayna si dhakhso leh ugu kala firidhsan tahay biyo qabow, laakiin runtii ma baabi'ineyso. Waxay baabi'isaa oo keliya marka codku uu kordho. Nooca degdegga ah kuma lahan daaweyn dusha sare leh geltox. Haddii qaddarka Gellxul uu weyn yahay, kala firidhsan ayaa si dhakhso leh, laakiin viscosity ayaa si tartiib ah kor ugu kacaya, iyo haddii qaddarka uu yar yahay, ka soo horjeedka ayaa run noqon doona.
6. Waa maxay jacaylka ku habboon ee ku habboon hydroxypropyl methylcelrelosuse (HPMC)?
Budada wareega guud ahaan waa 100,000 yuan, iyo shuruudaha hoobiyeyaasha ayaa ka sareeya, oo 150,000 yuan ayaa looga baahan yahay isticmaal fudud. Intaa waxaa dheer, shaqada ugu muhiimsan ee HPMC waa haynta biyaha, oo ay ku xigto dhumuc weyn. Budada wareega, illaa iyo inta ay haynta biyuhu wanaagsan yihiin oo ay taagan tahay mid taagan (70,000-80,000), sidoo kale waa macquul. Dabcan, waxa kor u kacaya sawirka, ayaa sifiican u haynta biyaha qaraabada ah. Markuu viscosisku ka badan yahay 100,000, codku wuxuu saameyn ku yeelan doonaa haynta biyaha. Mar dambe ma aha.
7. Waa maxay tilmaamayaasha farsamada ee ugu weyn ee hydroxypropyl methylcelrelose (HPMC)?
Hydroxypropyl iyo viscosity, dadka badankood waxay ka walaacsan yihiin labadan tilmaamayaasha. Kuwa leh hydroxypropyl nuxurka guud ahaan waxay leeyihiin haynta biyo ka fiican. Midda leh viscosity sare ayaa leh haynta biyaha ka fiican, si buuxda (gabi ahaanba), oo mid ka mid ah kan leh viscosity sare ayaa si fiican loogu isticmaalaa hoolkan.
8. Waa maxay aaladda ugu weyn ee ceeriin ee hydroxypropyl methylcelrellase (HPMC)?
Alaabada ugu weyn ee ceeriin ee hydroxypropylylulolose (HPMC): Waxaa lagu safeeyey suufka suufka ah, phimylne chloride, pretylne chloride, presylne-ka, iyo waxyaabaha kale ee ceeriin, aashitada, toluene, toopropanol, iwm.
9. Waa maxay shaqada ugu weyn ee codsiga HPMC ee budada wareega, oo miyaa loo sameeyaa kiimikada?
Budada wareega, HPMC waxay ku ciyaareysaa saddex doorar oo ah dhumuc, haynta biyaha iyo dhismaha.
Qulqulka: Cellulose waa la qaddarin karaa in la joojiyo oo xalka xalka u hayo kor iyo hoos, oo iska caabin karo inuu saq ka dhigo.
Haynta Biyaha: Ka dhig budada wareega si tartiib tartiib ah, oo ka caawiya kaalshiyamka Ash si aad uga jawaabto ficilka biyaha.
Dhismaha: Cellulose waxay leedahay saameyn saliiyin ah, kaas oo ka dhigi kara budada beddelka leh dhismaha wanaagsan.
Biyo ku darista biyaha budada ah oo gidaarka ku ridaya waa falcelin kiimikaad, maxaa yeelay walxaha cusub ayaa la sameeyay. Haddii aad derbiga ka saarto derbiga derbiga derbiga ah, ku kari budada, oo mar labaad u isticmaal, ma shaqeyn doonto maxaa yeelay walxaha cusub (Kalsium Calbor) ayaa la sameeyay. ) Sidookale.
The main components of ash calcium powder are: a mixture of Ca(OH)2, CaO and a small amount of CaCO3, CaO+H2O=Ca(OH)2—Ca(OH)2+CO2=CaCO3↓+H2O Ash calcium is in water and air Under the action of CO2, calcium carbonate is generated, while HPMC only retains water, assisting the better reaction of ash calcium, and does not participate in any reaction lafteeda.
10. HPMC waa unug aan inic-oonc-ka ahayn ether, markaa waa maxay non-ition?
Shuruudaha beenta ah, kuwa aan imaanaynin waa walxaha aan biyo ku lahayn. Ionition waxaa loola jeedaa geedi socodka elektrolyte ah oo loo kala diro dacwad lagu soo oogay ion oo si xor ah ugu dhaqaaqi kara xalka gaarka ah (sida biyaha, aalkolada). Tusaale ahaan, sodium chloride (NACL), milixyada aan cunno maalin kasta, waxaan ku kala dirnaa biyaha iyo ionizes si aan u soo saarno sodom ion (na +) kuwaas oo si wanaagsan loo soo dalacayo iyo khloride ion (cl) oo si xun loo eedeeyo. Taasi micnaheedu waa in la dhaho, marka HPMC lagu dhejiyo biyaha, uma kala saari doono ionsida lagu soo oogay, laakiin waxay ku jirtaa qaab moleekules.
11. Waa maxay heerkulka gel ee hydroxypropyl methylcellesulose la xiriirta?
Heerkulka geedka ee jel ee HPMC wuxuu la xiriiraa waxyaabaha ka kooban ee 'Metmc', ee hoostiisa hoose ee cudurka 'cothoxy', ee heerkulka gel-ka sare.
12. Ma jiraa xiriir ka dhexeeya dhibcaha budada ah iyo HPMC?
Budada budada ah ee budada isbadalka ah ayaa inta badan la xidhiidha tayada kaalshiyamka ash, wax yarna waxoogaa lagu sameeyo HPMC. Kalkay kacaamka hoose ee kalsiyum cawlan iyo saamiga aan habboonayn ee Cao iyo CA (Oh) 2 ee kaalshiyamka cawlan ayaa sababi doona lumis budada ah. Haddii ay wax ku qabato HPMC, markaa haddii HPMC ay leedahay haynta biyaha oo liita, waxay sidoo kale sababi doontaa lumis budo ah.
13. Waa maxay farqiga u dhexeeya nooca biyaha-qabow iyo nooca kulul ee hydroxypropyl methylcelrellase ee nidaamka wax soo saarka?
Nooca degdega ah ee HPMC-ga ayaa dusha sare ku daaweyneysa gelwal, waxayna si dhakhso leh ugu kala firidhsan tahay biyo qabow, laakiin runtii ma baabi'ineyso. Waxay baabi'isaa oo keliya marka codku uu kordho. Nooca degdegga ah kuma lahan daaweyn dusha sare leh geltox. Haddii qaddarka Gellxul uu weyn yahay, kala firidhsan ayaa si dhakhso leh, laakiin viscosity ayaa si tartiib ah kor ugu kacaya, iyo haddii qaddarka uu yar yahay, ka soo horjeedka ayaa run noqon doona.
