Isiphumo sokuqina kwe-cellulose ether

I-ether yeseliInika i-wet mortar ene-viscosity egqwesileyo, inokunyusa kakhulu amandla okubopha kwe-wet mortar kunye ne-grassroots, iphucule ukusebenza kwe-anti-sag kwe-mortar, esetyenziswa kakhulu kwi-plaster mortar, inkqubo yokukhusela yangaphandle kunye ne-brick bonding mortar. Isiphumo sokuqina kwe-cellulose ether sinokunyusa amandla okufana kunye nokulwa nokusasazeka kwezixhobo ezintsha ezisekwe kwisamente, ukuthintela ukuqhekeka, ukwahlulwa kunye nokopha kwe-mortar kunye nesamente, ingasetyenziswa kwi-fiber concrete, kwi-underground concrete nakwi-self-compact concrete.

I-ether yeselikwandisa i-viscosity yezinto ezisekwe kwisamente ukusuka kwi-viscosity yesisombululo se-cellulose ether. Ngokuqhelekileyo kusetyenziswa "i-viscosity" le metric ukuvavanya i-viscosity yesisombululo se-cellulose ether, i-viscosity ye-cellulose ether ngokubanzi ibhekisa kuxinzelelo oluthile (2%) lwesisombululo se-cellulose ether, ubushushu (20 ℃) ​​kunye nesantya sokucheba (okanye isantya sokujika, njenge-20 RPM), kunye nezibonelelo zesixhobo sokulinganisa, ezifana namaxabiso e-viscosity alinganisiweyo e-viscometer. I-viscosity yiparameter ebalulekileyo yokuvavanya ukusebenza kwe-cellulose ether kunye ne-cellulose ether, i-viscosity ephezulu yesisombululo, kokukhona i-viscosity yezinto ezisisiseko zesamente ingcono, i-viscosity yezinto ezisisiseko iyakwazi, ukumelana nokuhla kunye nokuxhathisa kokukhona amandla okusasazeka aqinileyo, kodwa ukuba i-viscosity inkulu kakhulu, inokuchaphazela ukuhamba kwezinto ezisisiseko sesamente kunye nokuhamba (njengokwakhiwa kwe-plaster mortar adhesive plaster). Ke ngoko, i-viscosity ye-cellulose ether esetyenziswa kwi-mortar exutywe nodaka idla ngokuba yi-15,000 ~ 60,000 Mpa. s-1, kwaye i-viscosity ye-cellulose ether kufuneka ibe phantsi kwi-self-leveling mortar kunye ne-self-compactconcrete eneemfuno eziphezulu ze-fluidity. Ukongeza, isiphumo sokutyeba se-cellulose ether siya kwandisa imfuneko yamanzi yezinto ezisekwe kwisamente, ngaloo ndlela sandise imveliso ye-mortar. I-viscosity yesisombululo se-cellulose ether ixhomekeke kubunzima be-molecular (okanye inqanaba le-polymerization) kunye noxinzelelo lwe-cellulose ether, ubushushu besisombululo, izinga lokucheba, kunye nendlela yovavanyo. Okukhona i-polymerization degree ye-cellulose ether iphezulu, kokukhona ubunzima be-molecular buphezulu, kokukhona i-viscosity yesisombululo sayo samanzi iphezulu; Okukhona idosi (okanye uxinzelelo) lwe-cellulose ether iphezulu, kokukhona i-viscosity yesisombululo sayo samanzi iphezulu, kodwa xa isetyenziswa kufuneka iqwalasele ukukhethwa kwedosi efanelekileyo, ukuze ingaxubeki kakhulu, ichaphazele ukusebenza kwe-mortar kunye nekhonkrithi; Njengoninzi lwe-liquids, i-viscosity yesisombululo se-cellulose ether iya kuncipha ngokunyuka kobushushu, kwaye okukhona i-concentration ye-cellulose ether iphezulu, kokukhona isiphumo sobushushu siba sikhulu; Isisombululo se-cellulose ether sidla ngokuba ngumzimba we-pseudoplastic oneempawu zokucheba. Okukhona izinga lokucheba liphezulu, kokukhona i-viscosity iphantsi.

Ngoko ke, ukuhlanganiswa kwesamente kuya kuncitshiswa ngamandla angaphandle, nto leyo enceda ekwakheni isamente, okwenza isamente ibe nokusebenza kakuhle kunye nokubambisana. Nangona kunjalo, isisombululo se-cellulose ether siya kubonisa iimpawu zolwelo lweNewtonian xa uxinzelelo luphantsi kakhulu kwaye i-viscosity incinci kakhulu. Xa uxinzelelo lusanda, isisombululo siveza kancinci kancinci iimpawu zolwelo lwe-pseudoplastic, kwaye okukhona uxinzelelo luphezulu, kokukhona i-pseudoplastic icacile.
