Hydroxypropyl methylcellulose, oo sidoo kale loo yaqaano hypromellose iyo cellulose hydroxypropyl methyl ether, ayaa laga sameeyay cellulose cudbi ah oo aad u saafi ah waxaana si gaar ah loogu nadiifiyaa xaaladaha alkaline.
farqiga u:
sifooyinka kala duwan
Hydroxypropyl methylcellulose: cad ama cad fiber-u eg budo ama granules, oo ka tirsan noocyada kala duwan ee aan-ionic ee isku dhafka cellulose, alaabtani waa semi-synthetic, polymer viscoelastic aan firfircoonayn.
Hydroxyethyl cellulose waa caddaan ama jaalle, ur aan lahayn, fiber aan sun ahayn ama budo adag, alaabta ceeriin ee ugu weyn waa alkali cellulose iyo etherification ethylene oxide, taas oo ah ether cellulose ah oo aan ionic ahayn.
Isticmaalku wuu ka duwan yahay
Warshadaha rinjiga, hydroxypropyl methylcellulose waxay ku milmayn wanaagsan biyaha ama dareerayaasha organic sida dhumuc weyn, kala firdhiso iyo xasiliye.Polyvinyl chloride waxaa loo isticmaalaa sidii rinji-saare loogu talagalay polymerization hakinta si loogu diyaariyo polyvinyl chloride, taas oo si weyn loogu isticmaalo maqaarka, alaabta waraaqaha, ilaalinta khudradda iyo khudradda, dunta iyo warshadaha kale.
Hydroxypropyl methylcellulose: ku dhawaad aan lagu milmi karin ethanol dhammaystiran, ether, acetone;milmay in xal colloidal hufan ama turbid biyo qabow, si ballaaran loo isticmaalo daahan, khadadka, fiilooyinka, midabaynta, waraaqaha, isku qurxiyo, sunta cayayaanka, macdanta processing Product, soo kabashada saliidda iyo warshadaha dawooyinka.
milmayn kala duwan
Hydroxypropyl methylcellulose: ku dhawaad aan lagu milmi karin ethanol dhammaystiran, ether, acetone;ku milmay xal kolloidal cad ama waxoogaa daruuro leh oo biyo qabow ah.
Hydroxyethyl cellulose (HEC): Waxay diyaarin kartaa xalal kala duwan oo viscosity kala duwan, oo waxay leedahay sifooyin milix wanaagsan ee electrolytes.
