Isticmaalka hydroxypropyl methylcellulose HPMC (heerka kiimikada maalinlaha ah)

1. Nooca kiimikada maalinlaha ah ee hydroxypropyl methylcellulose waa budo cad ama huruud yar, waana mid aan ur lahayn, dhadhan lahayn oo aan sun ahayn. Waxaa lagu milmi karaa biyo qabow iyo dareere isku dhafan oo walxo dabiici ah si loo sameeyo xal dareere ah oo hufan. Xalka biyaha wuxuu leeyahay firfircooni dusha sare ah, hufnaan sare iyo xasillooni xooggan, kala diristiisa biyahana saameyn kuma yeelanayso pH.

2. Saamaynta dhumucda iyo ka hortagga barafowga ee shaambada iyo jelka qubeyska, haynta biyaha iyo sifooyinka wanaagsan ee sameynta filimada ee timaha iyo maqaarka. Iyadoo ay soo badanayaan agabka ceeriin ee aasaasiga ah, isticmaalka cellulose (qafiifiyaha ka hortagga barafowga) ee shaambada iyo jelka qubeyska ayaa si weyn u yareyn kara kharashka oo gaari kara saameynta la rabo.
