Isesengura ry'impamvu zitera gucika kw'urukuta rwa gypsum
1. Isesengura ry'impamvu zo gusigwa ibikoresho fatizo bya gypsum
a) Sima y'inyubako idafite ibyangombwa
Gypsum yo kubaka irimo gypsum nyinshi ya dihydrate, bigatuma gypsum yo kubaka yihuta. Kugira ngo gypsum yo kubaka igire igihe cyo gufungura gikwiye, hagomba kongerwamo retarder nyinshi kugira ngo ibintu birusheho kuba bibi; gypsum ishongesha idafite amazi mu kubaka gypsum AIII Ingano nini ya AIII irakomeye kurusha gypsum ya β-hemihydrate mu cyiciro cya nyuma, kandi impinduka z'ingano ya gypsum yo kubaka ntizingana mu gihe cyo gusya, bigatuma habaho gucikagurika gukomeye; ingano ya gypsum ya β-hemihydrate ivurwa mu kubaka gypsum ni nke, ndetse n'ingano yose ya calcium sulfate ni nke; Gypsum yo kubaka ikomoka kuri gypsum ya shimi, ubugari ni buto, kandi hari ifu nyinshi zirenga mesh 400; ingano y'uduce twa gypsum yo kubaka ni imwe kandi nta ngano ibaho.
b) Inyongeramusaruro zidafite ubuziranenge
Ntabwo iri mu rugero rwa pH rukora cyane rw'ifatizo; ubushobozi bwa gel bw'ifatizo ni buke, ingano y'ikoreshwa ni nini, imbaraga za gypsum zo gusigwa ziragabanuka cyane, igihe kiri hagati y'igihe cyo gushyiraho bwa mbere n'igihe cyo gushyiraho bwa nyuma ni kirekire; igipimo cyo kubika amazi cya eteri ya selulose ni gito, amazi aratakaza vuba; eteri ya selulose ishonga buhoro buhoro, ntikwiriye gukoreshwa mu buryo bwa mashini.
Igisubizo:
a) Hitamo gypsum y’inyubako ishoboye kandi ihamye, igihe cyo kuyishyiraho mbere ni iminota irenga 3, kandi imbaraga zo kuyihindura zirenze 3MPa.
b) Hitamoeteri ya seluloseifite utunyangingo duto kandi ifite ubushobozi bwo kubika amazi neza.
c) Hitamo retarder idafite ingaruka nyinshi ku miterere ya gypsum yo gusigwa.
2. Isesengura ry'impamvu z'abakozi b'ubwubatsi
a) Rwiyemezamirimo w’umushinga akoresha abakozi badafite uburambe mu bwubatsi kandi ntakora amahugurwa ajyanye no kwihutisha imirimo. Abakozi b’ubwubatsi ntibaramenya neza imiterere y’ibanze n’ibikenewe mu bwubatsi byo gusigwa gypsum, kandi ntibashobora gukora hakurikijwe amabwiriza y’ubwubatsi.
b) Imicungire ya tekiniki n'imicungire myiza y'ishami rishinzwe amasezerano y'ubwubatsi ni mibi, nta bakozi b'ubuyobozi bahari aho imirimo y'ubwubatsi ibera, kandi imikorere y'abakozi itubahirije amategeko ntishobora gukosorwa ku gihe;
c) Inyinshi mu mirimo yo gusimbuza no gusimbuza gypsum isanzweho ni iyo gusukura, hibandwa ku bwinshi no kwirengagiza ubwiza.
Igisubizo:
a) Gutera inkunga imishinga yo gusimwa bishimangira amahugurwa mu kazi no gutangaza amakuru ya tekiniki mbere yo kubaka.
b) Gushimangira imicungire y'aho imirimo y'ubwubatsi ibera.
3. Isesengura ry'impamvu za plaster yo gusigwa
a) Ingufu za nyuma zo gusigwa gypsum ni nkeya kandi ntizishobora kwihanganira gucika intege guterwa no kubura amazi; imbaraga nke zo gusigwa gypsum ziterwa n'ibikoresho fatizo bidafite ubuziranenge cyangwa formula idasobanutse.
b) Ubudahangarwa bw'icyuma gitera plaster ntabwo buhagije, kandi plaster plaster irarundana hasi, kandi ubunini ni bunini, bigatuma habaho imiyoboro inyuranamo.
c) Igihe cyo kuvanga imashini yo gusiga gypsum ni gito, bigatuma imashini ivangwa mu buryo butangana, imbaraga nke, igabanuka kandi urwego rwa gypsum rwo gusiga rugasaguka mu buryo butangana.
d) Imashini yo gusiga plasta ya gypsum yashyizweho bwa mbere ishobora kongera gukoreshwa nyuma yo kongeramo amazi.
Igisubizo:
a) Koresha gypsum ikoze neza, yujuje ibisabwa na GB/T28627-2012.
b) Koresha ibikoresho bihuza kugira ngo urebe neza ko plastering gypsum n'amazi bivanze neza.
c) Birabujijwe kongeramo amazi muri mortigo yashyizweho bwa mbere, hanyuma ukongera kuyakoresha
4. Isesengura ry'impamvu z'ibikoresho by'ibanze
a) Kuri ubu, ibikoresho bishya byo ku nkuta bikoreshwa mu kubaka inyubako zakozwe mbere, kandi ingano yabyo yo kumisha ni nini cyane. Iyo imyaka y'inyubako idahagije, cyangwa ubushuhe bw'inyubako ari bwinshi cyane, nibindi, nyuma y'igihe cy'izuba, hagaragara icyuho ku rukuta bitewe no kubura amazi no kugabanuka, kandi urwego rwo gusigaho iracika.
b) Aho ibintu bibiri bitandukanye bihurira, kandi ibipimo byabyo byo kwaguka biratandukanye. Iyo ubushyuhe buhindutse, guhinduka kw'ibintu byombi ntibihuzwa, kandi hagaragara icyuho gitandukanye. Inkingi zisanzwe z'urukuta Icyuho gihagaze hagati y'imiringa n'icyuho kitambitse kiri munsi y'umuringa.
c) Koresha ifishi ya aluminiyumu kugira ngo usuke sima aho iherereye. Ubuso bwa sima buraryoshye kandi ntibufatanye neza n'urwego rwa sima yo gusimbuza. Urukuta rwa sima yo gusimbuza rworoshye kuva ku rwego rwo hasi, bigatuma habaho imitumba.
d) Ibikoresho by'ibanze na gypsum yo gusigwa bifite itandukaniro rinini mu mbaraga, kandi iyo bihujwe no kugabanuka no guhinduka k'ubushyuhe, kwaguka no guhindagurika ntibihuza, cyane cyane iyo ibikoresho by'urukuta rw'urumuri rwo hasi bifite ubucucike buke n'imbaraga nke, urwego rwa gypsum yo gusigwa rukunze gutuma urubura rucika. Gucikamo ibice, ndetse n'ahantu hanini ho gupfuka. e) Urugingo rw'ibanze rufite umuvuduko mwinshi wo kwinjiza amazi n'umuvuduko wo kwinjiza amazi vuba.
Igisubizo:
a) Urufatiro rwa sima rumaze gusigwa rugomba kuba rwumye iminsi 10 mu mpeshyi n'iminsi irenga 20 mu gihe cy'itumba iyo hari umwuka mwiza. Ubuso buroroshye kandi urufatiro rufata amazi vuba. Hagomba gushyirwaho uburyo bwo guhuza ibintu;
b) Ibikoresho byo kongera imbaraga nk'igitambaro cy'urukuta bikoreshwa aho inkuta z'ibikoresho bitandukanye zihurira
c) Ibikoresho byoroshye ku nkuta bigomba kubungabungwa neza.
5. Isesengura ry'impamvu z'ibikorwa by'ubwubatsi
a) Urusobe rw'ibanze ruba rwumye cyane hatabayeho kunyobwa neza cyangwa gukoresha uburyo bwo guhuza. Gypsum yo gusigwa ihura n'urusobe rw'ibanze, ubushuhe buri muri Gypsum yo gusigwa buhita bwinjira, amazi arabura, kandi ingano y'urusobe rw'uruziga rwo gusigwa iragabanuka, bigatera imitumba, bigatuma imbaraga ziyongera kandi bikagabanya imbaraga zo gufatanya.
b) Ubwiza bw'inyubako y'ifatizo ni bubi, kandi urwego rwa gypsum rwo gusigwamo ruba rurerure cyane. Iyo sima yo gusigwa ikoreshejwe rimwe, sima izagwa igakora imiyoboro itambitse.
c) Imiyoboro y'amashanyarazi ikoreshwa n'amazi ntiyakozwe neza. Imiyoboro y'amashanyarazi ikoreshwa n'amazi ntabwo yuzuyemo gypsum cyangwa beto nziza y'amabuye ifite uburyo bwo kwagura, bigatuma urwego rwa gypsum rucikamo ibice, bigatuma urwego rw'amashanyarazi rushyirwamo plaster rucikamo ibice.
d) Nta buryo bwihariye bwo gutunganya imbavu zo gukubita, kandi urwego rwa gypsum rwo gusiga rwakozwe ahantu hanini rucamo ibice ku mbavu zo gukubita.
Igisubizo:
a) Koresha uburyo bworoshye bwo gutunganya urwego rw'ibanze rufite imbaraga nke kandi rufata amazi vuba.
b) Ubunini bw'urwego rwa gypsum rwo gusigwa ni bunini cyane, burenga mm 50, kandi bugomba gukurwaho buhoro buhoro.
c) Gushyira mu bikorwa inzira yo kubaka no kongera imicungire myiza y'aho kubaka.
6. Isesengura ry'impamvu z'inyubako
a) Ikirere kiba cyumye kandi gishyushye.
b) Umuvuduko w'umuyaga mwinshi
c) Mu mpera z'impeshyi n'impeshyi, ubushyuhe buba buri hejuru kandi ubushuhe buba buri hasi.
Igisubizo:
a) Kubaka ntibyemewe iyo hari umuyaga mwinshi uri ku rwego rwa gatanu cyangwa hejuru, kandi kubaka ntibyemewe iyo ubushyuhe bw'ikirere buri hejuru ya 40 ℃.
b) Mu mpera z'impeshyi n'impeshyi, hindura uburyo bwo gukora plastering gypsum.
