1)Porogaramu nyamukuru yo kubaka ibikoresho byo mu rwego rwa selile ether
Umwanya wibikoresho byubwubatsi nigice nyamukuru gisabwa cyaselile ether. Ether ya selulose ifite ibintu byiza cyane nko kubyimba, kubika amazi, no kudindiza, bityo ikoreshwa cyane mugutezimbere no gutezimbere minisiteri ivanze (harimo na minisiteri ivanze na minisiteri ivanze), gukora PVC resin, gukora amarangi ya latx, putty, gufatisha amatafari, Imikorere yibikorwa byubaka ibikoresho birimo ibikoresho byubaka kandi bikarinda ibikoresho byubaka kandi bikarinda ibikoresho byubaka kandi bigakorwa neza, ubwubatsi bwa pasteri yubatswe ninyuma ninyuma yo gushushanya urukuta rwubwoko butandukanye bwimishinga. Bitewe nubunini bunini bwishoramari mubijyanye nubwubatsi bwubwubatsi, ubwoko butandukanye bwimishinga yubwubatsi iratatana, hariho ubwoko bwinshi, kandi iterambere ryubwubatsi riratandukanye cyane, kubaka ibikoresho byo mu rwego rwa selulose ether bifite ibimenyetso biranga uburyo bwagutse, isoko rikenewe, hamwe nabakiriya batatanye.
Muri moderi yo hagati na murwego rwohejuru rwo kubaka ibikoresho byo mu rwego rwa HPMC, icyiciro cyubwubatsi HPMC hamwe nubushyuhe bwa geli ya 75 ° C ikoreshwa cyane cyane mumashanyarazi avanze yumye hamwe nindi mirima. Ifite ubushyuhe bwo hejuru bwo guhangana nubushakashatsi bwiza. Imikorere yacyo ni ubushyuhe bwa gel Ntibishobora gusimburwa no kubaka ibikoresho byo mu rwego rwa HPMC kuri 60 ° C, kandi abakiriya bo mu rwego rwo hejuru bafite ibyo basabwa hejuru kurwego rwiza rwibicuruzwa. Mugihe kimwe, biragoye mubuhanga kubyara HPMC hamwe nubushyuhe bwa gel 75 ° C. Igipimo cyishoramari ryibikoresho bitanga umusaruro ni kinini, kandi umubare winjira ni mwinshi. Igiciro cyibicuruzwa kiri hejuru cyane ugereranije nubwubatsi bwibikoresho byo mu rwego rwa HPMC hamwe nubushyuhe bwa gel bwa 60 ° C.
Hejuru-ya PVC yihariye HPMC ninyongera yingirakamaro kubyara PVC. Nubwo HPMC yongewemo muke kandi ikabarirwa ku gipimo gito cyibiciro byumusaruro wa PVC, ingaruka zo gusaba ibicuruzwa nibyiza, bityo ibisabwa byujuje ubuziranenge ni byinshi. Hano hari bake mu gihugu no mumahanga bakora HPMC kuri PVC, kandi igiciro cyibicuruzwa byatumijwe mu mahanga kiri hejuru cyane ugereranije nibicuruzwa byo murugo.
2)Iterambere ryubwubatsi bwibikoresho Urwego Cellulose Ether Inganda
①Iterambere rihamye ryinganda zubwubatsi bwigihugu cyanjye rikomeje guteza isoko isoko ryo kubaka ibikoresho bya selile selile
Dukurikije imibare yashyizwe ahagaragara n’ikigo cy’igihugu gishinzwe ibarurishamibare, mu 2021, igipimo cy’imijyi y’igihugu cyanjye (umubare w’abatuye imijyi mu baturage b’igihugu) kizagera kuri 64.72%, cyiyongereyeho amanota 0.83 ugereranije n’umwaka wa 2020, kandi kwiyongera ugereranije n’umujyi wa 49,95% mu mwaka wa 2010. Mu buryo nk'ubwo, ubwiyongere bw’ibisabwa byose ku isoko ry’imitungo yimbere mu gihugu nabwo bwinjiye mu ntera ihamye, kandi itandukaniro ry’ibisabwa mu mijyi itandukanye ryarigaragaje cyane. Isabwa ry'amazu rikomeje kwiyongera. Mu bihe biri imbere, hamwe n’igabanuka ry’igipimo cy’inganda zikora inganda mu gihugu cyanjye ndetse no kongera umubare w’inganda zitanga serivisi, kongera uburyo bworoshye bw’akazi nko guhanga udushya no kwihangira imirimo, ndetse no guteza imbere imiterere y’ibiro byoroshye, ibisabwa bishya bizashyirwa imbere mu bucuruzi bwo mu mijyi, aho gutura no kuringaniza amazu. Ibicuruzwa bitimukanwa ibikenerwa mu nganda bizarushaho kuba byinshi, kandi inganda z’imbere mu gihugu n’inganda zubaka zinjiye mu gihe cyinzibacyuho.
Igipimo cy’ishoramari mu nganda zubaka, agace k’ubwubatsi bw’imitungo itimukanwa, ahantu huzuye, ahantu ho gushariza amazu n’imihindagurikire yacyo, urwego rwinjiza rw’abaturage n’ingeso zo gushariza, n’ibindi, ni byo bintu nyamukuru bigira ingaruka ku isoko ry’imbere mu gihugu kugira ngo hubakwe ibikoresho bya selile ya selile. Inzira yo mumijyi ifitanye isano ya hafi. Kuva mu mwaka wa 2010 kugeza 2021, igihugu cyanjye cyarangije ishoramari ry’imitungo itimukanwa hamwe n’inganda ziva mu bwubatsi byagumye ahanini bigenda byiyongera. Mu 2021, igihugu cyanjye cyateje imbere ishoramari ry’imitungo itimukanwa ryiyongereyeho tiriyari 14,76 z'amafaranga y'u Rwanda, umwaka ushize wiyongereyeho 4.35%; inganda zubwubatsi zose hamwe zasohotse zingana na tiriyari 29.31, ziyongereyeho 11.04% umwaka ushize.
Kuva mu mwaka wa 2011 kugeza 2021, impuzandengo y’ubwiyongere bw’imyubakire y’imyubakire y’imyubakire y’inganda mu gihugu cyanjye ni 6.77%, naho impuzandengo y’ubwiyongere bw’umwaka buri mwaka y’ahantu hubakwa amazu ni 0,91%. Mu 2021, ahantu hubakwa amazu y’inganda zubaka mu gihugu cyanjye hazaba metero kare miliyari 9,754, hamwe n’ubwiyongere bw’umwaka ku mwaka bwa 5.20%; ubuso bwubatswe buzaba bingana na metero kare 1.014, hamwe nubwiyongere bwumwaka-mwaka wa 11,20%. Iterambere ryiza ryinganda zubwubatsi bwimbere mu gihugu bizongera ikoreshwa ryibikoresho byubaka nka minisiteri ivanze, uruganda rwa PVC, amarangi ya latx, putty, hamwe na tile, bityo bigatuma isoko rikenerwa mu kubaka ibikoresho bya selile ya selile.
②Igihugu giteza imbere cyane ibikoresho byubaka icyatsi bigereranywa na minisiteri ivanze, kandi umwanya witerambere ryisoko ryubaka ibikoresho byo mu rwego rwa selile selile yongerewe
Mortar nikintu gihuza gikoreshwa mukubaka amatafari. Igizwe numubare runaka wumucanga nibikoresho bihuza (sima, paste lime, ibumba, nibindi) namazi. Uburyo gakondo bwo gukoresha minisiteri ni ukuvanga ahakorerwa, ariko hamwe niterambere ryikoranabuhanga ryinganda zubwubatsi no kunoza ibisabwa byubwubatsi bwubatswe, ibitagenda neza bivangwa na minisiteri ya minisiteri byagaragaye cyane, nkubwiza budahungabana, imyanda nini y’ibikoresho, ubwoko bumwe bwa minisiteri, ubwubatsi buke bw’imyubakire kandi byangiza ibidukikije, nibindi.
Ugereranije no kuvanga minisiteri, inzira ya minisiteri ivanze-yibanze ivanze cyane, kuvanga gufunga, gutwara imiyoboro ya pompe, gutera imashini ku rukuta, hamwe nibikorwa biranga kuvanga ubwabyo, bigabanya cyane kubyara ivumbi kandi byoroshye kubaka imashini. Kubwibyo minisiteri ivanze yiteguye ifite ibyiza byo gutuza kwiza, ubwoko butandukanye, ibidukikije byubaka urugwiro, kuzigama ingufu no kugabanya ibicuruzwa, kandi bifite inyungu nziza mubukungu nibidukikije. Kuva mu 2003, leta yasohoye inyandiko zinyuranye za politiki zigamije guteza imbere umusaruro no gukoresha minisiteri ivanze kandi itezimbere inganda zivanze na minisiteri.
Kugeza ubu, ikoreshwa rya minisiteri ivanze aho kuba minisiteri ivanze ku kibanza cyabaye bumwe mu buryo bw'ingenzi bwo kugabanya imyuka ihumanya ikirere PM2.5 mu nganda zubaka. Mu bihe biri imbere, hamwe n’ubuke bw’umucanga n’amabuye, ibiciro byo gukoresha umucanga mu buryo butaziguye ku nyubako biziyongera, kandi izamuka ry’ibiciro by’umurimo rizatuma kwiyongera gahoro gahoro ikoreshwa ry’imvange ivanze ku kibanza, kandi icyifuzo cya minisiteri ivanze n’inganda zubaka kizakomeza kwiyongera. Ingano yo kubaka ibikoresho byo mu rwego rwa selulose ether mubiteguye-bivanze na minisiteri muri rusange bingana na 2 / 10,000. Ongeramo selile ether ifasha kubyimba minisiteri ivanze, kugumana amazi no kunoza imikorere yubwubatsi. Ubwiyongere buzanatera ubwiyongere bwibisabwa mukubaka ibikoresho bya selile selile.
