Ukusetyenziswa kwe-EipponCell HPMC YB400 inezi mpawu zilandelayo kwizinto zomgangatho wokuzilinganisa :
1.Ukugcinwa kwamanzi
Ukugcinwa kwamanzi kodaka lwesamente esandula kuxutywa yinto ebalulekileyo echaphazela uzinzo lwamalungu ayo angaphakathi.I-HPMC YB400 sisongezo esisebenzayo esisetyenziselwa ukugcina ukufuma kudaka ixesha elide, nto leyo eyenza ukuba imathiriyeli yejeli ingene kwi-action epheleleyo ye-hydration.HPMC YB400 iimveliso kunye viscosity ngeenxa 400mpa.s badla ngokuqeshwa kwizicelo zodaka lokuzilinganisa.Oku kongezwa konyusa ukusebenza komgangatho wodaka kwaye kwandisa ukubumbana kwawo kukonke.Ngokuphucula amandla okugcina amanzi odaka lokuzilinganisa, i-HPMC YB400 iqinisekisa ukuba udaka lugcina ukuhambelana kwayo okunqwenelekayo, okwenza kube lula ukufaka isicelo kunye nokukhokelela kwiziphumo ezingcono kwiiprojekthi zokwakha.
2. Ulwelo
IHydroxypropyl methylcellulose (HPMC) YB400 yinto ebalulekileyo ekumiseleni ukugcinwa kwamanzi, ukungaguquguquki, kunye nokusebenza kolwakhiwo lodaka oluzilinganisayo.Ukusetyenziswa kodaka lokuzilinganisa, ulwelo luphawu oluphambili olumisela umgangatho wokuzilinganisa.Ngokulungelelanisa ubungakanani be-HPMC YB400 eyongeziweyo, i-fluidity yodaka inokulawulwa ngaphandle kokuchaphazela ukubunjwa kwayo okuqhelekileyo.Nangona kunjalo, kubalulekile ukuqinisekisa ukuba idosi ye-HPMC ikuluhlu olufanelekileyo ukuphepha iziphumo ezibi ekusebenzeni kodaka.Ukulawula ngokufanelekileyo isixa HPMC YB400 eyongeziweyo kunokunceda ukuqinisekisa ukungaguquguquki olufunwayo kunye fluidity lodaka self-leveling, okukhokelela iziphumo ezingcono kwiiprojekthi zokwakha.
3.Ixesha lokuvala
Ukongezwa kwe-EipponCell HPMC YB400 kumdaka kunokubangela ukulibaziseka kwixesha lokumisela umxube.Njengoko isixa HPMC YB400 ukwanda, esi siphumo iba ngakumbi.Oku kubangelwa ukubunjwa kwefilimu eyinkimbinkimbi, enokuthi ibe nempembelelo enkulu kwi-hydration yokuqala ye-samente kwaye iholele ekunciphiseni okukhulu kwexesha lokumisela.I-HPMC YB400 inokubangela impembelelo yokuncipha kudaka, kwaye inqanaba lesiphumo linxulumene ngokusondeleyo kwidosi yayo.
Amandla e-4.Flexural kunye namandla oxinzelelo
Ukongezwa kwe-HPMC YB400 kwizinto ezisekelwe kwisamente kunokubangela ukuhla kwamandla oxinzelelo kunye nokuguquguquka kodaka njengoko umthamo unyuka.Amandla luphawu olubalulekileyo lovandlakanyo lwesiphumo sokunyanga ezo mathiriyeli.
5.Bond amandla
Ukusebenza kokubambisana kodaka kuchaphazeleka kakhulu ngokongezwa kwe-HPMC YB400.I-HPMC yenza ifilimu ye-polymer esebenza njengetywina phakathi kwenkqubo yesigaba solwelo kunye namasuntswana e-cement hydration, ukuphucula ukugcinwa kwamanzi kunye nokusebenza kodaka.Xa isixa esifanelekileyo se-HPMC YB400 songezwa, iplastiki kunye nokuguquguquka kodaka kuyaphuculwa, okunciphisa ukuqina kwendawo yokutshintsha phakathi kodaka kunye ne-substrate interface.Oku, kwakhona, kunciphisa isakhono sokutyibilika phakathi kojongano kwaye kukhokelela kumandla okuqina okuqina.Isiphumo sokutywinwa se-HPMC YB400 sikwanceda ekunciphiseni ilahleko yamanzi kunye nokuphucula ukusebenza kakuhle kokufakwa kwamanzi ngexesha lokuseta kunye nenkqubo yokunyanga, okukhokelela kwimathiriyeli exineneyo kunye neyomelele ngakumbi yesamente.Ukongezwa kwe-HPMC YB400 akuphuculi kuphela ukusebenza kwebhondi yodaka kodwa kuphucula ukusebenza kwayo kunye nokuqina.
