I-HPMC kunye ne-HEMC kwicandelo lokwakha

I-HPMC kunye ne-HEMC zinendima efanayo kwizixhobo zokwakha. Ingasetyenziswa njenge-dispersant, i-arhente yokugcina amanzi, i-arhente yokuqina kunye ne-binder, njl. Isetyenziswa kakhulu kwi-samente mortar kunye nokubumba iimveliso ze-gypsum. Isetyenziswa kwi-samente mortar ukwandisa ukunamathela kwayo, ukusebenza kwayo, ukunciphisa ukutyibilika, ukuphucula i-viscosity kunye nokuncipha, kunye nokugcina amanzi, ukunciphisa ukulahleka kwamanzi kumphezulu wekhonkrithi, ukuphucula amandla, ukuthintela ukuqhekeka kunye nokuguquka kwetyuwa ezinyibilikayo emanzini, njl. Isetyenziswa kakhulu kwi-plaster esekelwe kwisamente, i-gypsum plaster, iimveliso ze-gypsum, i-masonry mortar, i-sheet caulking, i-caulking agent, i-tile adhesive, izinto zomgangatho ezizilinganiselayo, njl. Ingasetyenziswa njenge-arhente yokwenza ifilimu, i-thickener, i-emulsifier kunye ne-stabilizer kwi-emulsion coatings kunye ne-resin coatings enyibilikayo emanzini, inika ifilimu ukumelana okuhle kokukrala, ukufana kunye nokunamathela, kunye nokuphucula uxinzelelo lomphezulu, ukuzinza kwi-asidi kunye neziseko kunye nokuhambelana neepigment zesinyithi. Ngenxa yokuzinza kwayo okuhle kokugcinwa kwe-viscosity, ifanelekile ngakumbi njenge-dispersant kwi-emulsified coatings. Ngamafutshane, nangona isixa esikwinkqubo sincinci, siluncedo kakhulu kwaye sisetyenziswa kakhulu.

Ubushushu bejeli ye-cellulose ether bumisela uzinzo lwayo lobushushu kwiindlela ezisetyenziswa ngayo. Ubushushu bejeli ye-HPMC buhlala buqala kwi-60°C ukuya kwi-75°C, kuxhomekeke kuhlobo, umxholo weqela, iinkqubo ezahlukeneyo zemveliso zabavelisi abahlukeneyo, njl. Ngenxa yeempawu zeqela le-HEMC, inobushushu obuphezulu bejeli, buhlala bungaphezulu kwe-80°C. Ke ngoko, uzinzo lwayo phantsi kweemeko zobushushu obuphezulu luphezulu kunolo lwe-HPMC. Ngokwesiqhelo, phantsi kwendawo yokwakha eshushu kakhulu ehlotyeni, ukugcinwa kwamanzi kwe-HEMC kwi-marsh mix mortar ene-viscosity efanayo kunye ne-dosing kunenzuzo enkulu kune-HPMC.

I-cellulose ether ephambili kushishino lokwakha eTshayina iseyi-HPMC ikakhulu, njengoko ineentlobo ezininzi kunye namaxabiso aphantsi, kwaye inokukhethwa ngokukhululekileyo ngexabiso elipheleleyo. Ngophuhliso lwemarike yokwakha yasekhaya, ngakumbi ukwanda kolwakhiwo olusebenzisa oomatshini kunye nokuphuculwa kweemfuno zomgangatho wokwakha, ukusetyenziswa kwe-HPMC kwicandelo lokwakha kuya kuqhubeka nokwanda.
