Ukusetyenziswa kweHydroxypropyl Methylcellulose kwiWall Putty nakwiSkim Coat
IHydroxypropyl Methylcellulose (HPMC) yenye yezona zinto zibalulekileyo ezisebenzayo ezisetyenziswa kwi-wall putty kunye ne-skim coat formulations. Njenge-cellulose ether esebenza kakhulu, ibonelela ngokugcinwa kwamanzi, ukuqina, ukuphucula ukusebenza, kunye nokulawula ukugqitywa komphezulu. Ukuqonda isitshixo Ukusetyenziswa kwe-hydroxypropyl methylcellulose kwi-wall putty nakwi-skimcoat inceda abavelisi kunye nabaqulunqi bezinto zokugqiba ukuba bavelise izinto zokugqiba ezigudileyo, ezizinzileyo, nezilula ukuzisebenzisa.
Esi sikhokelo sichaza indlela esebenza ngayo i-HPMC kwiinkqubo ze-putty, ukuba zeziphi izibonelelo zokusebenza ezizisayo, indlela yokukhetha umgangatho ochanekileyo we-viscosity, kunye nendlela yokuphucula idosi ukuze ufumane iziphumo ezihambelanayo.
Zithini Izinto Zokugquma I-Wall Putty Nezokufaka I-Skim Coat?
I-wall putty kunye ne-skim coat ziingqimba ezincinci zokugqiba ezisetyenziswa phezu kweplasta okanye kumphezulu wekhonkrithi ukwenza i-substrate egudileyo, elungele ukupeyintwa. Ezi zinto zihlala zisekelwe kwezi zinto zilandelayo:
- Izibopheleli zesamente okanye zegypsum
- Izithambisi ezincinci (i-calcium carbonate, i-talc, njl.njl.)
- Izilungisi zePolymer
