I-HPMC kunye ne-HEMC kwintsimi yokwakha

I-HPMC kunye ne-HEMC zineendima ezifanayo kwizinto zokwakha. Ingasetyenziswa njenge-dispersant, i-agent yokugcinwa kwamanzi, i-agent e-thickening kunye ne-binder, njl. Isetyenziselwa udaka lwesamente ukunyusa ukunamathela kwayo, ukusebenza, ukunciphisa i-flocculation, ukuphucula i-viscosity kunye nokunciphisa, kunye nokugcina amanzi, ukunciphisa ilahleko yamanzi kwindawo yekhonkrithi, ukuphucula amandla, ukuthintela iintanda kunye nemozulu yeetyuwa ezinyibilikayo zamanzi, njl. i-adhesive, self-leveling floor material, etc. Ingasetyenziswa njenge-agent-forming agent, i-thickener, i-emulsifier kunye ne-stabilizer kwiingubo ze-emulsion kunye neengqungquthela ze-resin ezinyibilikayo zamanzi, ukunika ifilimu ukuxhathisa okulungileyo kwe-abrasion, ukufana kunye nokunamathela, kunye nokuphucula ukuxinana komphezulu, ukuzinza kwi-acids kunye neziseko kunye nokuhambelana nentsimbi yehagu. Ngenxa yokuzinza kwayo yokugcina i-viscosity, ifanelekile ngokukodwa njenge-dispersant kwiingubo ze-emulsified. Ngelizwi, nangona isixa esikwinkqubo sincinci, siluncedo kakhulu kwaye sisetyenziswa ngokubanzi.

Ubushushu be-gel ye-cellulose ether inquma ukuzinza kwayo kwe-thermal kwizicelo. ukushisa kwe-gel ye-HPMC ngokuqhelekileyo isuka kwi-60 ° C ukuya kwi-75 ° C, kuxhomekeke kuhlobo, umxholo weqela, iinkqubo ezahlukeneyo zokuvelisa abavelisi abahlukeneyo, njl. Ngenxa yeempawu zeqela le-HEMC, linobushushu obuphezulu be-gel, ngokuqhelekileyo ngaphezu kwe-80 ° C. Ngoko ke, ukuzinza kwayo phantsi kweemeko eziphezulu zokushisa kuphezulu kune-HPMC. Enyanisweni, phantsi kwendawo yokwakha eshushu kakhulu ehlotyeni, ukugcinwa kwamanzi kwe-HEMC kumdaka womxube omanzi kunye ne-viscosity efanayo kunye ne-dosing kunenzuzo enkulu kune-HPMC.

I-ether ye-cellulose ephakathi kwishishini lokwakha lase-China isekho ikakhulu i-HPMC, njengoko ineentlobo ezininzi kunye namaxabiso aphantsi, kwaye inokukhethwa ngokukhululekileyo kwiindleko ezibanzi. Ngophuhliso lwemarike yolwakhiwo lwasekhaya, ngakumbi ukwanda kokwakhiwa koomatshini kunye nokuphuculwa kweemfuno zomgangatho wokwakha, ukusetyenziswa kweHPMC kwintsimi yokwakha kuya kuqhubeka nokunyuka.
