1. Okwu mmalite
Concrete bụ ọkpụkpụ azụ nke ihe owuwu nke oge a, na-enye ike na ịdịte aka na-enweghị atụ. Ọ bụ ihe owuwu a na-ejikarị eme ihe n'ụwa niile, na-akpụzi obodo anyị na akụrụngwa anyị. Otú ọ dị, mmetụta gburugburu ebe obibi na nkwado nke ihe owuwu ihe aghọwo ihe na-esiwanye ike. N'okwu a, ihe mgbakwunye dị ka cellulose ether apụtala dị ka ihe ndị bụ isi maka ịkwalite arụmọrụ nke kọnkịtị ka ọ na-eme ka ọ dịkwuogide.
2. Gịnị bụ Cellulose Ether?
Cellulose ether bụ ezinụlọ nke polymers soluble mmiri nke sitere na cellulose eke, nke a na-enwetakarị site na osisi pulp ma ọ bụ owu. A na-emezi ya na kemịkalụ iji kwalite njide mmiri ya, na-agbakọ, na njide. Cellulose ethers na-abịa n'ụdị dị iche iche ma na-ejikarị eme ihe na ụlọ ọrụ dị ka ihe owuwu, ọgwụ, nri, na ihe ịchọ mma. Na kọmpat, a na-eji ọtụtụ ụdị cellulose ethers, gụnyere Hydroxyethyl Methylcellulose (HEMC) na Hydroxypropyl Methylcellulose (HPMC). A maara ihe mgbakwunye ndị a maka ikike ha imeziwanye arụmọrụ, nrapado, na ịdịte aka nke ngwakọta ihe.
3. Mmetụta nke Cellulose Ether na Njirimara Ihe
Cellulose ethers na-ekere òkè dị ịrịba ama na-emetụta ihe dị iche iche nke ihe. Mmetụta ha gụnyere:
Ịkwalite arụmọrụ na Flow: Cellulose ethers na-eme ka arụ ọrụ nke ihe na-arụ ọrụ na-arụ ọrụ site n'ibelata nkewa mmiri na ịkwalite ikike nke ngwakọta. Nke a dị oke mkpa n'ịhụ na enwere ike idobe kọnkịrị ngwa ngwa na kọmpat, nke dị mkpa iji nweta otu na ibelata oghere.
Njide mmiri na ọgwụgwọ emelitere: Cellulose ethers na-ejigide mmiri n'ime ngwakọta kọmpụta, na-egbochi ihicha n'oge. Nke a dị mkpa maka ọgwụgwọ dị irè, nke na-enye aka na mmepe nke ike na ogologo oge. Ngwọta nke ọma dị mkpa maka ibelata ihe ize ndụ nke mgbawa na ịhụ na arụ ọrụ ogologo oge.
Ịtọ oge njikwa: Mgbakwunye nke cellulose ethers nwere ike inye aka ịchịkwa nhazi oge nke ihe. Nke a bara uru karịsịa n'ọnọdụ ebe achọrọ ogologo ịrụ ọrụ, dị ka n'ọnọdụ ihu igwe na-ekpo ọkụ, ma ọ bụ mgbe a na-atụ anya igbu oge na ntinye.
Mgbakwunye dị mma na ike nkekọ: Cellulose ethers na-eme ka adhesion nke konkịtị dị iche iche dị iche iche, gụnyere ihe nkwado, nke dị oke mkpa maka iguzosi ike n'ezi ihe. Ha na-eme ka ike nkekọ dịkwuo mma, na-ebelata ihe ize ndụ nke delamination na imeziwanye àgwà zuru oke nke ihe ahụ.
Mmetụta na Rheology nke Concrete: Cellulose ethers na-emetụta rheological Njirimara nke ihe, na-emetụta ya eruba, viscosity, na deformation àgwà. Nke a dị mkpa karịsịa n'ihe gbasara ihe nkedo nke onwe (SCC), ebe a chọrọ njikwa nhazi nke ọma maka ngwa ngwa nke ọma.
4. Ngwa nke Cellulose Ether na Concrete
Cellulose ethers na-achọta ngwa n'ụdị dị iche iche nke ụdị ihe na ụzọ ihe owuwu, gụnyere:
Jiri na Conventional Concrete: N'ime ihe ndị a na-emekarị, a na-agbakwunye cellulose ethers iji melite arụmọrụ, belata ọdịnaya mmiri, na ịkwalite ịdị n'otu, na-eme ka ngwakọta na-adịgide adịgide na-adịgide adịgide.
Concrete na-ejikọta onwe ya (SCC): SCC na-adabere na njikwa reological ziri ezi, na-eme ka cellulose ether bụrụ ihe dị mkpa. Ha na-eme ka ihe na-erugharị na nhazi nke onwe nke SCC na-eme ka ọ dị mma ka ha na-ejigide nkwụsi ike.
Njikere-Mix Concrete: A na-ejikarị kọmpat na-agwakọta ihe n'ọrụ ihe owuwu. A na-agbakwunye cellulose ethers na ngwakọta ndị a iji hụ na ihe ahụ na-anọgide na-arụ ọrụ n'oge njem na ntinye.
Shotcrete na Gunite: N'ime ngwa ebe a na-efesa ihe n'elu elu, dị ka maka mgbidi ọwara ma ọ bụ ebe igwu mmiri, cellulose ethers na-enyere aka n'inweta nkwụsi ike na nrapagidesi ike.
Ihe eji eme eriri na-eme ka ọ dị ike: Mgbakwunye nke eriri na kọnkịta bụ ihe a na-emekarị iji welie ihe nhịahụ ya na ngbanwe. Cellulose ethers nwere ike melite mgbasa nke eriri n'ime ngwakọta ma welie n'ozuzu arụmọrụ nke eriri-ike kọmpụta.
Precast Concrete: Ngwaahịa a na-emepụta ihe, dị ka paịlị precast na ọkpọkọ, na-erite uru site na iji cellulose ethers iji kwalite arụmọrụ yana ibelata agụụ mmiri. Nke a na-ebute ihe precast kacha mma.
5. Nkwado na uru gburugburu ebe obibi
Ojiji nke cellulose ethers na ihe na-enye aka n'ọtụtụ nkwado na uru gburugburu ebe obibi, gụnyere:
Mbelata ojiji mmiri na ịbawanye ogologo oge: Site na imeziwanye njide mmiri na ịrụ ọrụ, cellulose ethers na-enye ohere maka ibelata ọdịnaya mmiri na ngwakọta ihe. Ọ bụghị nanị na nke a na-echekwa mmiri kamakwa ọ na-eme ka ọ dị ogologo oge site n'ibelata ihe ize ndụ nke mgbawa na imeziwanye ọgwụgwọ.
Iwetu akara ukwu Carbon: Oke mmiri-ciment dị ala enwetara site na iji ether cellulose nwere ike bute mbelata ikuku carbon. Nke a dị mkpa karịsịa n'ihe gbasara mbọ zuru ụwa ọnụ iji belata mmetụta gburugburu ebe obibi nke ihe owuwu.
Ntụnye aka na asambodo ụlọ LEED na Green: Ọtụtụ ụkpụrụ ụlọ akwụkwọ ndụ akwụkwọ ndụ, dị ka LEED (Leadership in Energy and Environmental Design), na-akwụghachi ụgwọ maka iji usoro ihe owuwu na-adigide. Ntinye nke cellulose ethers n'ime ihe nwere ike inyere aka na-arụ ọrụ ihe owuwu nweta isi na asambodo ndị a.
Mbelata ihe mkpofu n'ime ihe owuwu: arụ ọrụ ka mma yana mbelata ọdịnaya mmiri na-ebute obere ihe mkpofu n'oge
ihe owuwu. Nke a nwere ike iduga n'ichekwa ego na usoro ihe owuwu na-adịgide adịgide.
6. Ihe ịma aka na echiche
Ọ bụ ezie na ethers cellulose na-enye ọtụtụ uru, enwere ihe ịma aka na echiche na ojiji ha:
Ndakọrịta na Mgbakwụnye Ndị Ọzọ: Nkwekọrịta nke cellulose ethers na ihe mgbakwunye ndị ọzọ, dị ka superplasticizers na ihe ndị na-emepụta ikuku, kwesịrị ka e jiri nlezianya tụlee. Usoro ọgwụgwọ kwesịrị ekwesị na usoro ịgwakọta dị mkpa iji hụ na ihe mgbakwunye niile na-arụkọ ọrụ ọnụ.
Ntụle usoro onunu ogwu na ngwakọta: Usoro ziri ezi nke cellulose ethers dị oke mkpa maka ị nweta nsonaazụ achọrọ. Ịṅụbiga mmanya ókè ma ọ bụ ịṅụbiga ihe ókè nwere ike inwe mmetụta dị njọ n'arụ ọrụ ihe ahụ.
Ihe ndọghachi azụ na njedebe: Ọ bụ ezie na ethers cellulose na-enye ọtụtụ uru, ọ dị mkpa ịnakwere na ha nwere ike ọ gaghị abụ ihe ngwọta dị nha-dabara-niile maka ngwa ọ bụla. Ịghọta mkpa ụfọdụ nke oru ngo na ihe onwunwe nke cellulose ethers dị mkpa iji bulie uru ha.
7. Ọmụmụ ihe gbasara ikpe
Ihe atụ ndị mere eme nke ether cellulose ether ji eme ihe n’ọrụ ihe owuwu pụrụ igosi abamuru na ihe mmụta ndị a mụtara na ntinye ha. Ọmụmụ ihe nwere ike inye nghọta maka iji cellulose ethers eme ihe bara uru n'ụdị ihe owuwu dị iche iche.
8. Ụdị Ọdịnihu na Nnyocha na Cellulose Ether Jiri
Ojiji nke cellulose ethers na ihe bụ ihe na-agbanwe agbanwe na nyocha na mmepe na-aga n'ihu. Usoro n'ọdịnihu nwere ike ịgụnye:
Ọganihu na teknụzụ Cellulose Ether: Ndị na-eme nchọpụta na-arụ ọrụ na-aga n'ihu iji melite ngwaahịa ether cellulose, na-eme ka ihe onwunwe ha dịkwuo elu ma gbasaa ngwa ha na ụlọ ọrụ ihe owuwu.
Ịgbasa ngwa n'ime ihe owuwu na-adịgide adịgide: Dị ka nkwado na-aghọ nchegbu dị mkpa karị n'ime ihe owuwu, ọrụ cellulose ethers na-enweta ihe omume enyi na enyi na ume nwere ike ịgbasa.
Nnyocha na mmepe mmepe: Ndị otu ọha na ndị nkeonwe na-etinye ego na nyocha na ọrụ mmepe iji nyochaa ohere ọhụrụ maka cellulose ethers na-ewu. Nke a na-agụnye nyocha iji ha eme ihe na usoro ihe owuwu ụlọ dị elu.
9. Nkwubi okwu
Cellulose ethers na-arụ ọrụ na-arịwanye elu n'ịkwalite arụmọrụ na nkwado nke ihe na ụlọ ọrụ mmepụta ihe. Ikike ha imeziwanye arụmọrụ ọrụ, belata ọdịnaya mmiri, kwalite adhesion, na ịkwalite usoro ihe owuwu na-adịgide adịgide na-eme ka ha bụrụ ihe mgbakwunye bara uru na ihe owuwu nke oge a. Site na nyocha na mmepe na-aga n'ihu, cellulose ethers dị njikere inye aka na-eme ka mmekọrịta enyi na gburugburu ebe obibi na-adịgide adịgide n'ọdịniihu, kwekọọ n'ọchịchọ na-eto eto maka omume owuwu na-adịgide adịgide.
N'ime ụwa ebe nchegbu gburugburu ebe obibi na-aghọ ihe kachasị mkpa, iji cellulose ethers eme ihe na-anọchite anya nzọụkwụ na-aga n'ihu n'inweta ma arụmọrụ yana nkwado na-ewu ụlọ. Mpaghara a dị ike na-aga n'ihu na-etolite, yana nyocha na mmepe na-aga n'ihu iji kpughee ikike nke mgbakwunye ndị a dị iche iche. Dị ka omume ihe owuwu na-aga n'ihu na-eme mgbanwe iji gboo ihe ịma aka nke narị afọ nke 21st, cellulose ethers ka atọrọ ka ọ rụọ ọrụ dị mkpa n'ịwulite gburugburu ebe obibi na-adịgide adịgide na nke siri ike.
