Umphumela wokuqina we-cellulose ether

I-Cellulose EtherIfaka udaka olumanzi olunamandla okubonakala okuhle, ingakhulisa kakhulu amandla okubopha ngodaka olumanzi kanye notshani, ngcono ukusebenza kwe-anti-sag ngodaka, kusetshenziswe kabanzi ngodaka ngodaka, lusetshenziswe ngodaka lwangaphandle kanye nodaka lokufaka izitini. The thickening effect of cellulose ether can also increase the uniformity and anti-dispersion ability of new cement based materials, to prevent the stratification, segregation and bleeding of mortar and concrete, can be used in fiber concrete, underwater concrete and self-compacting concrete.

I-Cellulose EtherKwandisa ukubonwa kwezinto zokwenza usimende ezisekelwe ekuboneni kwesixazululo se-cellulose ether. Imvamisa sebenzisa "ukuhlakanipha" le metric ukuhlola isixazululo se-cellulose ether isixazululo, ukubonakala kwe-cellulose ether ngokusobala kubhekisele ekuhluphisweni okuthile (amazinga okushisa (20 ℃) ​​kanye ne-vear rate, njenge-20 Izimo ze-RPM), ezinikezwa yithuluzi lokulinganisa, njengokujikeleza kwe-VIPCOMETE elinganisekile amanani e-viscosity. I-Viscosity iyipharamitha ebalulekile yokuhlola ukusebenza kwe-cellulose ether kanye ne-cellulose ether, i-velicose ether, i-viscosity ye-vention sasekela, ukumelana nokumelana nekhono lokuhlakazeka, Kepha uma i-viscosity inkulu kakhulu, ingathinta ukuhamba kwesisekelo sesisekelo sokwenza usimende kanye ne-maneuverability (njengokwakhiwa kodaka olunamathela ngodaka). Ngakho-ke, i-viscosity ye-cellulose ether esetshenziswa ngodaka oluxutshwe omile imvamisa i-15,000 ~ 60,000 MPA. I-S-1, futhi ukubonwa kwe-verule ether kudingeka ukuba kwehliswe ngodaka lokuzimela nokuzimela ngezidingo eziphakeme ze-fluity. Ngaphezu kwalokho, umphumela wokuqina we-cellulose ether uzokhulisa imfuno yamanzi yezinto zokwenziwa komoya, ngaleyo ndlela yandisa ukuphuma kodaka. I-viscosity yekhambi le-ether ye-cellulose incike esimeni se-molecular (noma idigri ye-polymerization) kanye nokuhlushwa kwe-cellulose ether, izinga lokushisa lixazululwa, izinga lokuhlola, kanye nendlela yokuhlola. I-polymerization degree ye-cellulose ether, isisindo esikhulu molecular, okuphezulu kwesisombululo salo esinamanzi; Lapho ephakeme umthamo (noma ukugxila) kwe-cellulose ether, ukukhuphuka kwesisombululo sawo esinamanzi, kepha kuyasetshenziswa kufanele unake ukukhetha komthamo ofanele, ukuze ungahlanganisi phezulu kakhulu, kuthinte ukusebenza ngodaka nokhonkolo; Njengoketshezi oluningi, ukubonakala kwe-cellulose ether perher solution kuzokwehla ngokwanda kwezinga lokushisa, kanye nokuphakama kwe-cellulose ether, umphumela wokushisa kwezinga lokushisa; Isixazululo se-cellulose ether sivame ukuba ngumzimba we-pseudoplastic onesakhiwo sokuncipha kwe-shear. Izinga eliphakeme le-Shear, lehlise ukubonwa.

Ngakho-ke, ukubumbana kodaka kuzoncishiswa ngamandla angaphandle, okulungele ukwakhiwa okusolayo kodaka, okwenza udaka akwazi ukusebenziseka okuhle nokubumbana. Kodwa-ke, isixazululo se-ether ye-cellulose sizokhombisa izici ze-newtonian fluid lapho okuhlushwa kuphansi kakhulu futhi i-viscosity incane kakhulu. Lapho okuhlushwa kunyuka, ikhambi kancane kancane liveza izici ze-Pseudoplastic fluid, futhi likhuphuka okuhlushwa, okusobala kakhulu i-Pseudoplastic.
