Maxay yihiin arrimaha saameeya viscosity hydroxypropyl methylcellulose?

Codsiga hydroxypropyl methylcellulose waa mid aad u ballaaran, wax badanna waa inuu ku sameeyo viscositykiisa, iyo viscosity looga baahan yahay isticmaalka kala duwan ee hydroxypropyl methylcellulose sidoo kale waa ka duwan yahay, marka marka aan isticmaalno alaabtiisa, ugu horreyntii, waa inaan ogaano waxa uu muujinayo waa, laakiin viscosity ee hydroxypropyl methylcellulose waxaa saameeya arrimo badan. Haddii kaydku aanu taxadir lahayn, waxa laga yaabaa inay sababi karto maw-galnimadeeda. Marka loogu talagalay hydroxypropyl methylcellulose, Maxay yihiin arrimo ku saabsan viscosity-keeda? Aan idin baro si kooban.

Guud ahaan, viscosity ee hydroxypropyl methylcellulose waxaa saameyn doona arrimaha soo socda:

1. Heerka sare ee polymerization of cellulose ether iyo miisaanka molecular weyn, sare viscosity ee xal aqueous;

2. The sare qiyaasta (ama fiirsashada) ee ether cellulose, sare viscosity ee ay xal aqueous, laakiin taxadar waa in la qaadaa si loo doorto qiyaasta ku haboon marka la isticmaalayo, si aanay u saamayn waxqabadka hoobiye iyo shubka haddii qiyaasta ayaa aad u sareysa;

3. Sida dareerayaasha intooda badan, viscosity of cellulose ether xal waxay hoos u dhigi doontaa korodhka heerkulka, iyo xoojinta sare ee ether-ka cellulose, saamaynta heerkulka;

Guud ahaan, marka aan xakameyno viscosity ee hydroxypropyl methylcellulose, waxaan ka fiirinaa qodobada kor ku xusan, sidaas darteed waa in aan hubinno oo aan isticmaalno marar badan marka la kaydinayo hydroxypropyl methylcellulose.
