Wall putty chalkingiya kwenza umphezulu wodonga ubukeke ungaguquki kwaye urhabaxa xa ubamba, ungcoliswe lula ngothuli, uchaphazela isiphumo sokuhombisa ngokubanzi. Ukongeza, i-putty chalking eludongeni iya kukhokelela ekunciphiseni ukunamathela phakathi komgangatho we-putty kunye ne-substrate eludongeni, ethanda ukuwa, ngaloo ndlela ichaphazela umgangatho kunye nomgangatho jikelele wodonga. Esi siganeko sibangelwa ikakhulu zizizathu ezisixhenxe eziphambili:umgangatho wokuzalisa,ukungalingani komlinganiselo wefomula,ukungabikho kwemfuneko[...]

Kulwakhiwo lwangoku, ukufuna ukuqina, ukuguquguquka, kunye nokuzinza kuye kwaqhuba ukwamkelwa kwezinto eziphambili.I-Redispersible Polymer Powder (RDP)umi phambili kule nguqu, eguqula iinkqubo zesamente zemveli. Njengenxalenye ephambili kwiidaka ezisebenza kakhulu,iRDPiphucula ukuncamathelisa, ukuthintela amanzi, kunye neempawu zoomatshini, oko kuyenza ibaluleke kakhulu [...]

I-HPMC idlala indima engenakuphinda ithathelwe indawo njengesongezo esiphambili ekuqulunqweni kwezinto zokuncamathelisa iithayile. Le powder emhlophe ibonakala iqhelekileyo yenye yezinto eziphambili ezimisela ukusebenza kwe-adhesives tile. Kweli phepha, siza kuxubusha ngokunzulu indlela i-HPMC ephucula ngayo ukusebenza kwe-adhesive tile kunye [...]

IHydroxypropyl Methyl Cellulose Ether (HPMC),I-Methyl Hydroxyethyl Cellulose Ether (MHEC/HEMC), kwayeI-Hydroxyethyl Cellulose Ether (HEC)zonke zibalulekile izinto eziphuma kwiselulosi ezisetyenziswa kakhulu kumashishini ahlukeneyo. Ezi ether ze-cellulose zifumaneka ngokuguqulwa kweekhemikhali ze-cellulose yendalo, zibanika iimpawu ezizodwa ezidibana [...]

I-Hydroxypropyl Methyl Cellulose ineempembelelo ezithile kumandla odaka lwesamente

IHydroxypropyl methyl cellulose idlala indima ebalulekileyo kudaka lwesamente.

IHydroxypropyl Methyl Cellulose (HPMC) yi-non-ionic cellulose ether polymer esekelwe kwi-cellulose, i-polymer yendalo ephuma kwi-cotton linter yokucoca.

Impembelelo ye-VAE powder kwiipropati ezisisiseko zodaka olungenamanzi.

Uvavanyo lwesamente yesamente yindlela ebalulekileyo yovavanyo kwintsimi yezinto zokwakha, ezisetyenziselwa ukuvavanya ukusebenza kunye nomgangatho wesamente yesamente.

IHydroxypropyl methylcellulose (HPMC) iphuma kwi cellulose esetyenziswa kakhulu kumashishini ahlukeneyo kwaye yaziwa ngokuguquguquka kwayo kunye nokuzinza. Nangona kunjalo, isiphumo samaqondo obushushu aphezulu kwi-HPMC sisihloko esinomdla kakhulu ngenxa yempembelelo enokubakho ekusebenzeni kunye neepropathi zale khompawundi ibalulekileyo.
