Iyada oo la adeegsanayo tikniyoolajiyada casriga ah iyo tas-hiilaadka, gacan-qabsiga tayada sare leh, qiimo macquul ah, taageero gaar ah iyo iskaashi dhow oo lala yeesho macaamiisha, waxaanu u heellannahay inaanu bixinno qiimaha ugu habboon ee macaamiisheena ee Ganacsatada Jumlada ah ee Shiinaha Qalalan Hoobiye Isku-dhafan ee HPMC/Mhec/HEC/ Kiimikada Dhismaha CMC, Nagu kalsoonow, waxaad ka heli kartaa dawo ka wanaagsan warshadaha walxaha baabuurta.
Anagoo adeegsanayna tignoolajiyada casriga ah iyo tas-hiilaadka, gacan tayo sare leh oo adag, qiimo macquul ah, taageero gaar ah iyo wada shaqayn dhow oo lala yeesho macaamiisha, waxaanu u heellannahay inaanu bixinno qiimaha ugu habboon ee macaamiisheenaShiinaha HPMC, hydroxypropyl methylcellulose, Badeecadahayaga waxaa loo dhoofiyaa adduunka oo dhan. Macaamiishayadu waxay had iyo jeer ku qanacsan yihiin tayadayada la isku halayn karo, adeegyada macaamiisha ku jihaysan iyo qiimaha tartanka. Hadafkayagu waa "inaan sii wadno si aan u kasbano daacadnimadaada anagoo u hurayna dadaalkeena horumarinta joogtada ah ee alaabtayada iyo adeegyadayada si aan u hubinno ku qanacsanaanta isticmaalayaashayada, macaamiisheena, shaqaalaha, alaab-qeybiyeyaasha iyo bulshooyinka caalamka ee aan iska kaashano".
Sharaxaada Alaabta
CAS NO.: 9004-65-3
Hydroxypropyl Methylcellulose (HPMC) Fasalka saabuunta waa budo cad oo leh milmi biyo wanaagsan. Hydroxypropyl Methylcellulose (HPMC) Fasalka saabuunta waxaa lagu daaweeyaa habka wax soo saarka ee gaarka ah, waxay ku siin kartaa viscosity sare leh firidh degdeg ah iyo xal daahsan. Heerka saabuunta HPMC si degdeg ah ayaa loogu milmi karaa biyo qabow oo waxay kordhisaa saamaynta dhumucdiisuna aad u fiican. Hydroxypropyl Methyl Cellulose (HPMC) waxay ku siin kartaa viscosity dhammaan noocyada nidaamka surfactant. Dusha sare ee budada waxaa lagu daaweeyay hannaan gaar ah, sidaa darteed si degdeg ah ayaa loogu milmi karaa biyaha oo aan lahayn wax qallafsan, qulqulaya ama roobab inta lagu jiro kala diri.
Fasalka saabuunta ee HPMC si degdeg ah ayaa loogu kala firdhi karaa iyadoo lagu dhex daray biyo qabow iyo walxo dabiici ah. Dhowr daqiiqo ka dib, waxay gaari doontaa joogteynta ugu badan waxayna sameyn doontaa xal muuqda oo hufan. Xalka aqueous wuxuu leeyahay dhaqdhaqaaqa dusha sare, daahfurnaanta sare, xasilloonida xooggan, iyo kala dirida biyaha ma saameynayso pH. Marka darajada saabuunta ee HPMC lagu milmi karo biyo qabow si degdeg ah oo ay kordhiso saamaynta dhumucdiisuna aad u fiican. Hydroxypropyl Methyl Cellulose HPMC waxaa loo isticmaalaa dareeraha saabuunta, gacmo nadiifiyaha, jelka khamriga, shaambada, dareeraha dhaqida, kiimikooyinka nadiifinta sida dhumuc iyo kala firdhiso.
darajada saabuuntahydroxypropyl methylcellulosewaxaa loo isticmaalaa saabuunta dharka lagu dhaqo, inta badan waxay u shaqeysaa sidii dhumuc dejineed, emulsifying stabilizer, iyo dhumucduna kala firdhiso, taas oo si weyn u kordhin karta viscosity ee alaabta iyo awooda in ay dhex gasho wasakhaha.
