Tilmaamaha 'Hydroxypropyl Metyl celluose'

Degdegga degdegga ah ee hydroxypropyl methylcelrellose ether waxaa loogu talagalay alaabada biyaha ku saleysan. Dusha sare ee hydroxypropylkyl methylrellase ether waxaa lagu daaweeyaa gelwal hoostiisa heerkul gaar ah iyo malax. Jeega hydroxyprose chetyl chether ether sidan loo daaweeyay oo keliya ayaa lagu kala firdhiyaa biyo qabow dhexdhexaad ah iyadoo aan la isticmaalin iyo viscosity, oo door ka ciyaara dib-u-dhigga bararka. Waqtigaan, xalka aqueous waxaa lagu kiciyaa 5-10 daqiiqo ama marka loo habeeyo jawiga xalka (qiimaha pH) inuu noqdo alkaline, hydroxypropyl methylcelrelose ethertyl chether wuxuu bilaabmayaa oo abuuraa viscosity. Noocan la daweeyay ee la daweeyay waxaa badanaa lagu tilmaamaa nooc deg deg ah.

Astaamaha ee ku saabsan hydroxypropylylrcellellalose ayaa ah in markii ay ku dhacdo biyaha qabow, laakiin waxay qaadataa waqti ay ku kacdo, sababtoo ah kaliya waxay ku kala firidhsan tahay biyaha marxaladda hore, mana ku milmayso macno weyn. Muuqaalkiisu wuxuu gaarayaa qiimaha ugu badan ee qiyaastii 20 daqiiqo ama ka badan. Faa'iidada tan ayaa ah in loo isticmaalo warshado gaar ah oo aan lahayn budo qalalan, ama marka loo baahan yahay in la kala diro oo biyo kulul looma adeegsan karo xaaladaha qalabka iyo sababao kale awgood. Degdegga ah ee hydroxypropyl methylcelrelose wuxuu xalliyaa dhibaatadaas oo kale.

Si dhakhso ah uqoran hydroxypropylpellerose methylrcellerose si dhakhso leh ayuu ugu kala firdhiyaa biyaha (heerka dambe), gaar ahaan marxaladda dambe, gaar ahaan 95%) iyo isku-darka guud, oo xallinaya dhibaatooyinka ku jira codsiyada la taaban karo. Caqabadaha, ballaarinta duurka dalabka, sida dalabka xabagta dhismaha, arjiga koollada dhismaha, iyo abaabulka tuubooyinka dareeraha ah, iyo beero gaar ah sida kiimikada maalinle ah.

Waxaan soo bandhignay qalabka wax soo saarka ee horumarsan ee adduunka iyo tikniyoolajiyada, oo leh qadka wax soo saarka casriga ee cellex, oo ay hubiso in ay bixiyaan isticmaaleyaasha alaabooyin lagu qanco oo leh nidaamkeeda xakameynta tayada leh, nidaamka imtixaanka iyo adeegga goobta ku habboon. Hadda badeecada ugu sareysa waa hyroxypropyl methylulolose chmc, hydroxyetyl ​​cell hyphcyl HEC, hydroxypropyl Starchdyl Etch, oo taxane ah oo taxane ah oo tabane ah. Alaabada ayaa si balaadhan loogu isticmaalaa dhismaha, warshadaha kiimikada, rinjiga, warshadaha kiimikada ee maalinlaha ah, warshadaha militariga iyo meelaha kale, oo loo kala qaado aqal-finsida, isku-darka, xasilinta, iwm.

Ku tiirsanaanta tayada wax soo saarkeeda iyo xaaladdeeda iyo saameyn ku yeelashada budada budada ah ee budada ah, iyo qaybta hoose ee sii wadida howlgalka shirkadda ee tayada, haddana waxay iskaashi la leedahay soo-saareyaasha caalamiga ah iyo kuwa taranka ee loo yaqaan badeecadaha dhameystiran. Hawlgallada taageeraya: polypropylenene-ka, fiber alwaax, oo ah istaarch, budada aalkolada aalkolada polyvinyl, dayactirka budada ah, kabixiyaha biyaha, qaabka kaalshiyamka ah iyo waxyaabaha kale ee lagu daro budada ah
