Ii-cellulose ethers luhlobo lwe-polymer compound enyibilikayo emanzini eyenziwe emva kokuguqulwa kweekhemikhali ze-cellulose. Zisetyenziswa kakhulu kwizixhobo zokwakha, ingakumbi xa zisetyenziswa kwi-mortar enemiphumo ebalulekileyo.
Iipropati ezisisiseko ze-cellulose ethers
Ii-cellulose ethers luhlobo lwe-polymer olufunyenwe ngonyango lweekhemikhali lwe-cellulose yendalo. Ii-cellulose ethers eziqhelekileyo ziquka i-hydroxypropyl methylcellulose (HPMC), i-methylcellulose (MC), i-carboxymethylcellulose (CMC) njl. Ziyakwazi ukunyibilika kakuhle kwaye ziqine, kwaye zinokwenza izisombululo ze-colloidal ezifanayo nezizinzileyo emanzini. Ezi mpawu zenza ii-cellulose ethers zisetyenziswe kakhulu kwizixhobo zokwakha.
Iimpawu eziphambili ze-cellulose ethers ziquka:
Ukutyeba: kunokunyusa kakhulu i-viscosity yeenkqubo zolwelo.
Ukugcinwa kwamanzi: Inamandla okugcina amanzi kakhulu kwaye inokuthintela ukulahleka kwamanzi ngexesha lenkqubo yokwakha.
Iimpawu zokwenza ifilimu: Ingenza ifilimu efanayo phezu komphezulu wento ukuyikhusela nokuyiphucula.
Ukuthambisa: Kuphucula ukusebenza kolwakhiwo lwesamente, okwenza kube lula ukuyifaka nokuyila.
Indima ephambili ye-cellulose ether kwi-mortar
Indima ye-cellulose ether kwi-mortar ibonakala kakhulu kwezi zinto zilandelayo:
1. Ukuphucula ukugcinwa kwamanzi
I-mortar isengozini yokulahlekelwa ngamandla kunye neengxaki zokuqhekeka ngenxa yokulahleka kwamanzi ngexesha lokwakhiwa. I-cellulose ether inokugcinwa kakuhle kwamanzi kwaye inokwenza isakhiwo senethiwekhi kwi-mortar ukuze ivale umswakama kwaye inciphise ukufuma kwamanzi kunye nokulahleka, ngaloo ndlela iphucula ukugcinwa kwamanzi kwi-mortar. Oku akupheleli nje ekwandiseni ixesha lokuvulwa kwe-mortar, kodwa kuqinisekisa ukuba i-mortar imanzi ngokupheleleyo ngexesha lenkqubo yokuqina, okwandisa amandla ayo kunye nokuqina kwayo.
2. Phucula ukusebenza kolwakhiwo
Isiphumo sokuthambisa se-cellulose ether senza i-mortar ithambe ngexesha lokwakha, kube lula ukuyisebenzisa nokuyisasaza, kwaye kuphucula ukusebenza kakuhle kokwakha. Kwangaxeshanye, ipropathi yokuqina ye-cellulose ether yenza i-mortar ibe ne-thixotropy elungileyo, oko kukuthi, iba ncinci xa iphantsi kwamandla okucheba kwaye ibuyele kwi-viscosity yayo yokuqala emva kokuba amandla okucheba enyamalele. Olu phawu lwenza i-mortar ingabi namathuba amaninzi okuwa ngexesha lokwakha kwaye igcine imo entle yokwakha.
3. Yandisa ukunamathela kwesamente
I-cellulose ether inokwenza isakhiwo senethiwekhi esifanayo kwi-mortar, yonyuse amandla okunamathela kwi-mortar, kwaye iphucule ukunamathela kwayo kwi-substrate. Oku kunokuthintela i-mortar ukuba yahlulwe kwizinto ezisisiseko ngexesha lenkqubo yokuqina kwaye kunciphise ukuvela kweengxaki zomgangatho ezifana nokugoba nokuwa.
4. Phucula ukumelana nokuqhekeka
Ipropati yokwenza ifilimu ye-cellulose ether ivumela i-mortar ukuba yenze ifilimu encinci kumphezulu ngexesha lenkqubo yokuqina, edlala indima yokukhusela kwaye inciphisa impembelelo yendalo yangaphandle kwi-mortar. Kwangaxeshanye, iipropati zokugcina amanzi kunye nokuqina zinokunciphisa ukuqhekeka okubangelwa kukulahleka kwamanzi kwi-mortar kwaye ziphucule ukumelana kwayo nokuqhekeka.
Iziphumo ezithile ze-cellulose ethers kwiimpawu zedaka
Impembelelo ethile ye-cellulose ether ekusebenzeni kodaka ingahlalutywa ngokweenkcukacha kwezi nkalo zilandelayo:
1. Ukusebenza kakuhle
I-mortar eyongezwe nge-cellulose ether isebenza ngcono ngokwendlela esebenza ngayo. Ukugcinwa kwamanzi kunye nokuthamba kwayo okuhle kwenza i-mortar ibe lula ngexesha lokwakha, kube lula ukuyisebenzisa, kwaye kube lula ukuyakha. Kwangaxeshanye, isiphumo sokuqina kwe-cellulose ether sinokuphucula i-thixotropy ye-mortar, ukuze i-mortar ikwazi ukugcina imo yayo kakuhle ngexesha lokwakha kwaye kube nzima ukuyithoba nokuwa.
2. Amandla
Ukugcinwa kwamanzi kwe-cellulose ether kwenza i-mortar ikwazi ukugcina umswakama owaneleyo ngexesha lenkqubo yokuqina, ikhuthaza ukusabela komswakama wesamente, kwaye yenze isakhiwo semveliso yomswakama oqinileyo, ngaloo ndlela iphucula amandla e-mortar. Ukongeza, ukusasazwa okufanayo kunye nesiphumo sokubopha se-cellulose ether kunokwenza isakhiwo sangaphakathi se-mortar sizinze ngakumbi, sinciphise ukuqhekeka okuncinci, kwaye siphucule amandla ngokubanzi.
3. Ukuqina
Ngenxa yokuba i-cellulose ether inokugcina ngokufanelekileyo ukufuma kwi-mortar, i-mortar inokwenza isakhiwo esifanayo ngexesha lenkqubo yokuqina, inciphise ukwenzeka kokuqhekeka kokuqhekeka, ngaloo ndlela iphucula ukuqina kwe-mortar. Ifilimu eyenziwe yi-cellulose ether inokukhusela umphezulu we-mortar ukuya kwinqanaba elithile, inciphise ukukhukuliseka kwe-mortar yimeko-bume yangaphandle, kwaye iphucule ngakumbi ukuqina kwayo.
4. Ukugcinwa kwamanzi kunye nokumelana nokuqhekeka
I-cellulose ether inokuphucula kakhulu ukugcinwa kwamanzi kwi-mortar, ivumela i-mortar ukuba igcine umswakama owaneleyo ngexesha lenkqubo yokuqina kwaye inciphise ukwenzeka kwemingxunya yokuncitshiswa. Ukongeza, ipropathi yokwenza ifilimu ye-cellulose ether ivumela i-mortar ukuba yenze ifilimu ekhuselayo kumphezulu, inciphisa impembelelo yendalo yangaphandle kwi-mortar kwaye iphucule ukumelana kwayo neengxunya.
Ukusetyenziswa kwe-cellulose ether kwi-mortar kunemiphumo ebalulekileyo. Ukugcinwa kwayo kakuhle kwamanzi, ukuqina kwayo, ukwenza ifilimu kunye nokuthambisa kuye kwaphucula kakhulu ukusebenza kolwakhiwo, amandla, ukuqina kunye nezinye iinkalo ze-mortar. Ke ngoko, i-cellulose ether, njengesongezelelo esibalulekileyo, isetyenziswa kakhulu kwizixhobo zokwakha zanamhlanje kwaye iye yaba yindlela ebalulekileyo yokuphucula ukusebenza kwe-mortar.
