1. Nnyocha nyocha nke mmetụta nkecellulose etherna plastic free shrinkage nke ngwa agha
Mortar bụ ihe a na-ejikarị eme ihe n'ọrụ ihe owuwu, na nkwụsi ike nke ịrụ ọrụ ya nwere mmetụta dị mkpa n'ịdị mma nke ụlọ. Ngwunye plastik na-enweghị ihe ọ bụla bụ ihe nwere ike ime na ngwa agha tupu ọ gbasie ike, nke ga-ebute nsogbu dị ka mgbawa na ngwa agha, na-emetụta ịdịte aka ya na ihe ịchọ mma. Cellulose ether, dị ka ihe mgbakwunye a na-ejikarị eme ihe na ngwa agha, nwere mmetụta dị mkpa na mbelata ngwa ngwa na-enweghị plastik.
2. Ụkpụrụ nke cellulose ether mbenata plastic free shrinkage nke ngwa agha
Cellulose ether nwere ezigbo njigide mmiri. Ọnwụ mmiri n'ime ngwa agha bụ ihe dị mkpa na-eduga na mbelata nke plastik na-efu. Otu hydroxyl dị na cellulose ether molecules na oxygen atom na ether bond ga-emepụta njikọ hydrogen na mkpụrụ ndụ mmiri, na-atụgharị mmiri n'efu ka ọ bụrụ mmiri a kpara akpa, si otú ahụ na-ebelata mmiri ozuzo. Dịka ọmụmaatụ, n'ime nchọpụta ụfọdụ, a chọpụtara na site na mmụba nke cellulose ether doseji, ọnụ ọgụgụ mmiri na-efunahụ na ngwa agha na-ebelata n'ahịrị. Dị kamethyl hydroxypropyl cellulose ether (HPMC), mgbe usoro onunu ogwu bụ 0.1-0.4 (oke ntakiri), ọ nwere ike ibelata ọnụ ọgụgụ mmiri simenti na-efu site na 9-29%.
Cellulose ether na-eme ka akụrụngwa rheological dịkwuo mma, usoro netwọk porous na nrụgide osmotic nke cement ciment ọhụrụ, na ihe na-emepụta ihe nkiri ya na-egbochi mgbasa nke mmiri. Usoro usoro a na-ejikọta ọnụ na-ebelata nchekasị nke mgbanwe mmiri na-ebute na ngwa agha, si otú a na-egbochi nkwụsị nke plastik n'efu.
3. Mmetụta nke cellulose ether onunu ogwu na plastic free shrinkage nke ngwa agha
Nnyocha e mere egosiwo na nbibi rọba nke simenti n'efu na-ebelata n'ahịrị site na mmụba nke cellulose ether onunu ogwu. Na-ewere HPMC dị ka ihe atụ, mgbe usoro onunu ogwu bụ 0.1-0.4 (mass fraction), plastic free shrinkage nke ciment ngwa agha nwere ike ibelata 30-50%. Nke a bụ n'ihi na ka usoro onunu ogwu na-abawanye, mmetụta njigide mmiri ya na mmetụta mgbochi ndị ọzọ na-ebelata na-aga n'ihu na-abawanye.
Otú ọ dị, a pụghị ịbawanye dose nke cellulose ether ruo mgbe ebighị ebi. N'otu aka ahụ, site n'echiche akụ na ụba, nnukwu mgbakwunye ga-abawanye ọnụ ahịa; N'aka nke ọzọ, oke cellulose ether nwere ike inwe mmetụta na-adịghị mma na ihe ndị ọzọ nke ngwa agha, dị ka ike nke ngwa agha.
4. Ihe mmetụta nke cellulose ether pụtara na plastic free shrinkage nke ngwa agha.
Site n'echiche nke ngwa injinịa bara uru, mgbakwunye ezi uche dị na ya nke cellulose ether na ngwa agha nwere ike belata mbelata nke plastik n'efu nke ọma, si otú a na-ebelata ihe omume mgbawa ngwa agha. Nke a dị oke mkpa maka imeziwanye ogo ụlọ, karịsịa maka imeziwanye ịdịte aka nke ihe owuwu dịka mgbidi.
Na ụfọdụ pụrụ iche oru ngo na elu chọrọ maka ngwa agha àgwà, dị ka ụfọdụ elu-ọgwụgwụ residential ụlọ na nnukwu ọha ụlọ, site ịchịkwa mmetụta nke cellulose ether na plastic free shrinkage nke ngwa agha, e nwere ike hụ na oru ngo na-ezute elu àgwà ụkpụrụ. .
5. Atụmanya nyocha
Ọ bụ ezie na enweela ụfọdụ nchọpụta nyocha na mmetụta nke cellulose ether na plastic free shrinkage nke ngwa agha, a ka nwere ọtụtụ akụkụ nke nwere ike nyochaa na omimi. Dịka ọmụmaatụ, usoro mmetụta nke ụdị cellulose ethers dị iche iche na plastik free shrinkage nke ngwa agha mgbe ha na-emekọ ihe ọnụ na mgbakwunye ndị ọzọ.
Site na mmepe nke teknụzụ ihe owuwu na-aga n'ihu, ihe ndị a chọrọ maka ịrụ ọrụ ngwa agha na-abawanye kwa mgbe. A chọrọ nyocha ọzọ maka otu esi ejikwa nke ọma ngwa cellulose ether na ngwa agha iji nweta mmetụta kachasị mma nke igbochi nchikota plastik n'efu ma na-eburu n'uche njirimara ndị ọzọ nke ngwa agha.
