Isticmaalka hydroxypropyl methylcellulose

1. Warshadaha dahaarka: Waxaa loo isticmaalaa sidii dhumuc, kala firdhiyo iyo xasilinta warshadaha daahan, oo waxay leedahay waafaqsan wanaagsan ee biyaha ama dareerayaasha organic. Sida rinji-saar.

2. Warshadaha wax soo saarka dhoobada: Waxaa si weyn loo isticmaalaa sida xidhe ee wax soo saarka dhoobada.

3. Kuwo kale: Alaabtan waxa kale oo si weyn loogu isticmaalaa hargaha, alaabta waraaqaha, ilaalinta khudaarta iyo khudaarta iyo warshadaha dunta, iwm.

4. Khad daabacaadda: Waxa loo isticmaalaa dhumuc ahaan, kala firdhisa iyo xasilinta warshadaha khadka, waxayna leedahay iswaafajin wanaagsan oo biyaha ama dareeraha organic.

5. Caag: loo isticmaalo sidii samaynta wakiilka sii daynta, jilcisa, saliidaha, iwm.

6. Polyvinyl chloride: Waxaa loo isticmaalaa sida kala firdhiso soo saarista chloride polyvinyl, waana wakiilka ugu muhiimsan ee diyaarinta PVC by polymerization hakinta.

7. Warshadaha dhismaha: Sida wakiilka biyaha-haysta iyo dib-u-dejiya hoobiye sibidhka, waxay ka dhigi kartaa hoobiye mid la shubi karo. Malaasta, gypsum, budada suufka ah ama qalabka kale ee dhismaha si loo hagaajiyo faafinta iyo u dheereeyo wakhtiga shaqada. Waxaa loo isticmaali karaa sida foornada koollada, marmar, qurxinta caagga ah, xoojinta koollada, iyo sidoo kale waxay yareyn kartaa qaddarka sibidhka. Waxqabadka xajinta biyaha ee hydroxypropyl methylcellulose HPMC waxay ka hortagtaa qulqulka inuu dillaaco sababtoo ah si degdeg ah u qallaji codsiga ka dib, waxayna kordhisaa xoogga ka dib qallajinta.

8. Warshadaha dawooyinka: alaabta daahan; walxaha xuubabka; Qalabka polymer-ka ee lagu xakameynayo heerka-is-diyaarinta sii-deynta joogtada ah; xasiliyayaal; wakiilada shaqada ka joojinaya; xabagta kiniinka; wakiilada kordhinta viscosity

dabeecadda:

1. Muuqashada: budo cad ama ka baxsan.

2. Cabbirka walxaha; heerka gudbinta 100 mesh wuxuu ka weyn yahay 98.5%; heerka gudbinta ee 80 mesh waa 100%. Cabbirka walxaha gaarka ah waa 40 ~ 60 mesh.

3. Heerkulka kaarboonaynta: 280-300 ℃

4. Cufnaanta muuqata: 0.25-0.70g/cm (badanaa ku dhawaad ​​0.5g/cm), cufnaanta gaarka ah 1.26-1.31.

5. heerkulka midabka: 190-200 ℃

6. Xiisadda dusha sare: 2% xal aqueous waa 42-56dyn/cm.

7. Solubility: Ku milmay biyaha iyo qaar dareere ah, sida ethanol/biyaha, propanol/biyaha, iwm. Xalalka aqueous ayaa dusha firfircoon. Daah-furnaanta sare, waxqabadka xasilloon, qeexitaannada kala duwan ee alaabooyinka waxay leeyihiin heerkul jel oo kala duwan, isbeddelka milanka leh ee viscosity, hoos udhaca viscosity, ka weynaanta, noocyada kala duwan ee HPMC waxay leeyihiin kala duwanaansho gaar ah oo waxqabadka ah, iyo kala dirida HPMC ee biyaha ma saameynayso by pH

8. Marka la yareeyo maadada methoxyl, barta gelku way kordhisaa, milanka biyaha ee HPMC ayaa hoos u dhacaya, iyo dhaqdhaqaaqa dusha sare ayaa sidoo kale hoos u dhacaya.

9. HPMC waxa kale oo uu leeyahay sifooyinka awoodda dhumucdiisuna, caabbinta milixda, budada dambaska hoose, xasiloonida pH, haynta biyaha, xasilloonida cabbirka, hantida film-samaynta aad u fiican, iyo tiro balaadhan oo ah caabbinta enzyme, kala firdhisanaan iyo isku xidhnaan.
