Kubaka imashini zikoreshwa mu gusimbuza imashini byateye imbere mu myaka ya vuba aha. Gusimbuza imashini byanavuye mu kuva aho bisanzwe bivangira kugeza ku imashini isanzwe ikoreshwa mu gusimbuza imashini n'imashini ivanze amazi. Ubushobozi bwayo bwiza n'ubudahangarwa ni byo bintu by'ingenzi bitera imbere mu iterambere ry'imashini zikoreshwa mu gusimbuza imashini, kandi imashini zikoreshwa mu gusimbuza imashini. Inyongera y'ibanze ifite uruhare rudasimburwa. Muri ubu bushakashatsi, binyuze mu guhindura ubukana n'amazi ya selulose, no mu guhindura sintetike, ingaruka z'ibipimo by'igerageza nko gufata amazi, gutakaza imiterere y'amasaha 2, igihe cyo gufungura, kudakomera, no kugenda kw'imashini zikoreshwa mu gusimbuza imashini zakozweho ubushakashatsi byizweho. Amaherezo, byagaragaye ko imashini zikoreshwa mu gusimbuza imashini zifite imiterere yo gufata amazi menshi n'ubushobozi bwiza bwo kuzipfunyika, kandi zikwiriye cyane cyane mu kubaka imashini zikoreshwa mu gusimbuza imashini, kandi ibipimo byose by'imashini zikoreshwa mu gusimbuza imashini byujuje ibisabwa ku rwego rw'igihugu.
Igipimo cyo kubika amazi mu gikoresho cyo gusigwa
Igipimo cyo kubika amazi mu gikoresho cyo gusigwa kiriyongera iyo ubukana bwa eteri ya selulose buva kuri 50.000 kugeza 100.000, kandi ni ukugabanuka iyo buva kuri 100.000 kugeza 200.000, mu gihe igipimo cyo kubika amazi cya eteri ya selulose yo gusukwa mu mashini kigeze ku kigero kirenga 93%. Uko igipimo cyo kubika amazi mu gikoresho cyo gusigwa kiri hejuru, ni ko amahirwe make yo kuva amaraso mu gikoresho cyo gusigwa. Mu igerageza ryo gusukwa hakoreshejwe imashini isukura mu gikoresho cyo gusigwa, byagaragaye ko iyo igipimo cyo kubika amazi cya eteri ya selulose kiri munsi ya 92%, igikoresho cyo gusigwa kirava amaraso nyuma yo gushyirwaho igihe runaka, kandi, mu ntangiriro yo gusukwa, biroroshye cyane kuziba umuyoboro. Kubwibyo, iyo dutegura igikoresho cyo gusigwa gikwiriye ubwubatsi bw'imashini, twagombye guhitamo eteri ya selulose ifite igipimo cyo kubika amazi kiri hejuru.
Gusiga sima mu masaha 2 nta bufatanye
Dukurikije ibisabwa na GB/T25181-2010 “Ready Mixed Mortar”, igisabwa cyo gutakaza imiterere y’isaha ebyiri kuri sima isanzwe yo gusigwa ni munsi ya 30%. Ubukana bwa 50.000, 100.000, 150.000, na 200.000 bwakoreshejwe mu igerageza ryo gutakaza imiterere y’isaha 2. Bigaragara ko uko ubukana bwa eteri ya selulose bwiyongera, agaciro k’ubukana bwa sima mu masaha 2 kazagabanuka buhoro buhoro, ibi kandi bigaragaza ko ubukana bwa eteri ya selulose Uko agaciro kaba kari hejuru, niko ubukana bwa sima burushaho kuba bwiza kandi ubushobozi bwa sima bugakomeza kurwanya ivangura. Ariko, mu gihe cyo gutera imiti, byagaragaye ko mu gihe cyo kugabanya imiterere y’isaha nyuma, kubera ko ubukana bwa eteri ya selulose ari bwinshi cyane, guhuza hagati ya sima n’icyuma bizaba byinshi, ibyo bikaba bidafasha mu bwubatsi. Kubwibyo, mu gihe cyo kwemeza ko sima idatuje kandi ntigasenyuke, uko ubukana bwa eteri ya selulose buba buke, niko birushaho kuba byiza.
Amasaha yo gufungura sima yo gusigwa
Nyuma y’uko sima yo gusigwa ikoreshejwe ku rukuta, bitewe n’uko amazi yinjira mu rukuta ndetse n’ubushuhe buva ku buso bwa sima, sima izakora imbaraga runaka mu gihe gito, ibyo bizagira ingaruka ku iyubakwa ry’ubugari bukurikira. Igihe cyo gufunga cyasesenguwe. Agaciro ka viscosity ya ether ya cellulose kari hagati ya 100.000 na 200.000, igihe cyo gushyiraho ntigihinduka cyane, kandi ifite isano runaka n’igipimo cyo kubika amazi, ni ukuvuga ko uko amazi agumana amazi menshi, ni ko igihe cyo gushyiraho sima kiba kirekire.
Uburyo bwo gusigwa plaster bugenda butemba
Gutakaza ibikoresho byo gutera imiti bifitanye isano rikomeye n’uburyo ibintu bigenda bihinduka. Mu gihe cy’ikigereranyo kimwe cy’amazi n’ibikoresho, uko ibintu bigenda bihinduka, ni ko agaciro k’ibintu bigenda bihinduka, bivuze ko uko ibintu bigenda bihinduka, ni ko ibintu bigenda bihinduka, kandi ibikoresho bikagenda bigabanuka. Kubwibyo, ku iyubakwa ry’ibikoresho byo gutera imiti mu buryo bwa mashini, uburyo ibintu bigenda bihinduka, ni ko ibintu bigenda bigabanuka.
Ubudahangarwa bw'imashini yo gusigwa
Nyuma y’uko sima yo gusigwa ikoreshejwe ku rukuta, iyo sima idakomeye, sima izagwa cyangwa ikanyerera, bigira ingaruka zikomeye ku buryo sima igongana, bizatera ibibazo bikomeye ku bwubatsi bukurikiyeho. Kubwibyo, sima nziza igomba kuba ifite thixotropy nziza kandi ikanagwa neza. Igerageza ryagaragaje ko nyuma y’uko eteri ya selulose ifite ubukana bwa 50.000 na 100.000 ishyizweho ihagaze, amatafari yamanukaga neza, mu gihe eteri ya selulose ifite ubukana bwa 150.000 na 200.000 idacika. Inguni iracyahagaze ihagaze, kandi nta kunyerera kuzabaho.
Imbaraga z'urukuta rwo gusigwa
Hakoreshejwe eteri za selulosi 50.000, 100.000, 150.000, 200.000, na 250.000 mu gutegura ingero za morti yo gusigwa kugira ngo ikoreshwe mu buryo bw'imashini, byagaragaye ko uko ubushyuhe bwa eteri ya selulosi bwiyongera, agaciro k'imbaraga za morti yo gusigwa kagabanuka. Ibi biterwa nuko eteri ya selulosi ikora umuti ufite ubushyuhe bwinshi mu mazi, kandi umubare munini w'udupira tw'umwuka duhamye uzashyirwa mu gihe cyo kuvanga mortiyo. Nyuma yuko sima ikomera, utu dupira tw'umwuka tuzakora umubare munini w'imyanda, bityo agaciro k'imbaraga za mortiyo kagabanuke. Kubwibyo, mortiyo yo gusigwa ikwiriye gukoreshwa mu bwubatsi bw'imashini igomba kuba ishoboye kuzuza agaciro k'imbaraga gasabwa n'igishushanyo, kandi eteri ya selulosi ikwiye igomba gutoranywa.
