Marka rinjiga la samaynayo, viscosity ee HPMC (Hydroxypropyl Methylcellulose) ayaa door muhiim ah ka ciyaara gaaritaanka joogtada la rabo, faafinta, iyo waxqabadka guud.Maqaalkani wuxuu ujeedkiisu yahay inuu bixiyo hab cilmiyaysan si loo go'aamiyo viscosity ugu fiican ee HPMC ee samaynta rinjiga, iyadoo la tixgelinayo arrimo ay ka mid yihiin nooca midabka, habka codsiga, iyo sifooyinka rinjiga ee la doonayo.
Faham Doorka HPMC ee Samaynta Rinjiga:
HPMC waxay u adeegtaa wax-qabad badan oo isku dhafan qaabaynta rinjiga, ka qayb qaadashada xakamaynta viscosity, haynta biyaha, iyo guryaha samaynta filimada.Viscositykeedu wuxuu si toos ah u saameeyaa socodka iyo sifooyinka sinnaanta rinjiga, iyo sidoo kale awoodda uu u leeyahay inuu u hoggaansamo meelo kala duwan.
Tixgeli Nooca Midabka iyo Xooga saarista:
Midabka kala duwan waxay u baahan yihiin heerar kala duwan oo ah viscosity HPMC si loo gaaro kala firdhisanaanta ugu wanaagsan iyo xasiloonida samaynta rinjiga.Guud ahaan, midabada aadka u uruursan ama culus, sida titanium dioxide ama oksijiinta birta, ayaa laga yaabaa inay u baahdaan viscosity sare HPMC si ay u ilaaliso ka joojinta la midka ah oo looga hortago dejinta.Midabka khafiifka ah, sida midabada organic ama midabada hufan, ayaa laga yaabaa inay u baahdaan viscosity hoose ee HPMC si loo hubiyo kala firdhisanaan habboon oo aan saameyn ku yeelan hufnaanta.
Go'aami Habka Codsiga iyo Astaamaha Rinjiga:
Habka codsiga iyo sifooyinka rinjiga ee la doonayo ayaa sidoo kale saameeya viscosity-ka ugu fiican ee HPMC.Tusaale ahaan:
a.Codsiga buraash/Roller: Viscosity High HPMC ayaa inta badan la door bidaa buraashka ama rullaluistuyada si loo hubiyo in rinjiga kantaroolo oo wanaagsan, kala firdhiso oo yaraada, iyo haynta burushka/ rullaluistuyada
b.Codsiga buufinta: Viscosity hoose HPMC waxaa caadi ahaan loo isticmaalaa arjiga buufinta si loo fududeeyo atomization oo loo gaaro xitaa caymiska.
c.Iska caabbinta Sag: Si loo hagaajiyo iska caabbinta sag-caabbinta loogana ilaaliyo rinjiga inuu ka tifqxo ama ku dago dusha sare, HPMC ayaa laga yaabaa inay lagama maarmaan noqoto.
Samee Tijaabooyin Rheological:
Si cilmi ahaan loo go'aamiyo viscosity ugu fiican ee HPMC ee samaynta rinjiga, tijaabooyinka rheological ayaa la samayn karaa.Tijaabooyinku waxay cabbiraan socodka iyo habdhaqanka qallafsanaanta rinjiga ee xaaladaha la xakameeyey.Natiijadu waxay hagi kartaa xulashada viscosity HPMC iyadoo la tixgelinayo arrimo ay ka mid yihiin heerka xiirid, diiqad xiirid, iyo muuqaalada viscosity.
Tijaabi oo hagaaji:
Iyada oo ku saleysan natiijooyinka baaritaanka rheological, tiro badan oo ah viscosities HPMC ayaa loo aqoonsan karaa inay yihiin musharrixiinta suurtagalka ah samaynta rinjiga.Samee tijaabooyin yar-yar adiga oo samaynaya muunado rinji leh oo kala duwan oo HPMC ah oo ku dhex jira inta la cayimay.Qiimee halbeegyada muhiimka ah sida sifooyinka codsiga, simida, caabbinta sag, iyo sifooyinka qalajinta.Hagaji viscosity HPMC sida loogu baahan yahay si loo gaaro waxqabadka rinjiga la doonayo.
Go'aaminta viscosity-ga ugu fiican ee HPMC ee samaynta rinjiga waxay u baahan tahay hab cilmiyeysan oo tixgelinaya arrimaha sida nooca midabka, habka codsiga, iyo sifooyinka rinjiga ee la doonayo.Fahamka doorka HPMC, samaynta tijaabooyinka rheological, iyo tijaabinta iyo hagaajinta shaybaarada qaabaynta, soosaarayaasha rinji waxay gaari karaan viscosity-ka ugu fiican si kor loogu qaado socodka rinjiga, simida, dhejinta, iyo waxqabadka guud.Waa lagama maarmaan in la dhufto dheelitirka saxda ah si loo gaaro sifooyinka rinjiga ee la rabo iyadoo la ilaalinayo shuruudaha wax ku oolka ah ee habka codsiga.
