Inzu ya prefab yabanje gukoreshwa nkuburaro bwigihe gito ahubatswe kandi yatangiriye muri Guangdong.Nyuma y'ivugurura no gufungura, Shenzhen, nk'icyitegererezo cy'ivugurura no gukingura, yari ikeneye byihutirwa kubaka amazu atandukanye, maze abashinzwe ubwubatsi n'abakozi b'ubwubatsi basuka muri Shenzhen baturutse mu gihugu hose.Kugira ngo ikibazo cy’amacumbi y’abakozi gikemuke, abashinzwe iterambere bashizeho amacumbi yigihe gito.Amazu y'agateganyo ahazubakwa ubusanzwe yari isuka y'agateganyo yubatswe na tile ya asibesitosi nkububiko bwo hejuru.Nubwo igiciro cyari gito, ugereranije namazu ya prefab nyuma, byari byoroshye kandi bifite umutekano muke, kandi mubyukuri nta muyaga no guhangana n’umuyaga.Nyuma ya za 90, igihugu cyashimangiye imicungire y’ahantu hubakwa hagamijwe umutekano w’abakozi;asibesitosi kandi yemejwe ko ari ibintu byangiza kandi bitera kanseri.Umujyi wa Shenzhen urabuza neza gukoresha ibiti bya asibesitosi byubaka amacumbi yigihe gito, kandi amacumbi yigihe gito agomba kuba afite urwego runaka rwumutekano, hamwe n’umuyaga no guhangana n’umuyaga.Hashyizweho kandi ibihano mu gihugu hose.Ibi biganisha ku buryo butaziguye kubyara amazu ya prefab hamwe na PU amabati.
Mu minsi ya mbere, nta mwambaro umwe wemeranijweho wo kubaka amazu ya prefab.Ukurikije ibihe byakurikiranye, amazu ya prefab arashobora kugabanywamo ibyiciro bitatu:
1. Inzu ya sima.
Amazu yigihe gito ahubatswe hakiri kare yubatswe namakipe yubwubatsi ubwabo.Amazu yigihe gito yubatswe, hamwe nibisobanuro bihanitse, agomba kuba inzu ifite inkuta za sima nkumubiri nyamukuru.Amabati ya asibesitosi amaze guhagarikwa, amabati ya PU yakoreshejwe mu buryo butaziguye.Ngiyo inzu ya mbere ya prefab: inzu ya sima prefab.Ariko, inzu ya sima prefab ntabwo igendanwa.Nubwo ibikoresho byubwubatsi bikoreshwa muburyo butaziguye, igihe cyo kubaka ni kirekire kandi ikiguzi ni kinini.Umushinga umaze kurangira, biragoye gusenya inzu ya sima, isesagura abakozi benshi nibikoresho;ntishobora gukoreshwa.
2. Magnesium na fosifore yimuka yicyumba.
Inzu ya Magnesium-fosifore ni inzu ya prefab nyayo, ikoresha ikibaho cya magnesium-fosifore nkibikoresho byurukuta hamwe nicyuma cyoroheje nka skeleti yinzu yubuyobozi.Ubwiza bwimiterere yicyuma cyoroheje abantu bamenyekana buhoro buhoro.Ikoranabuhanga ryo guterana ryinama yubuyobozi naryo riragenda rikura.Ibipimo byo gukora no kwishyiriraho amazu ya prefab bigenda bikorwa buhoro buhoro.Ariko hamwe no kugaragara kwicyuma cyamabara prefab inzu, magnesium fosifore prefab inzu yabaye ibicuruzwa byinzibacyuho.
3. Inzu y'amabara prefab inzu.
Ikibaho cya Magnesium-fosifore kiroroshye muburemere kandi gifite imbaraga nke, kandi imikorere yacyo idakoresha amazi kandi ntigishobora kugereranywa nicyuma cya EPS.Bidatinze, abantu basanze ikibaho cya magnesium-fosifore kidakwiriye nkibikoresho byo hanze, ariko bikwiriye gusa nkibikoresho byimbere.Yatangiye rero gukoresha ibara ryicyuma cyibara rifite imikorere myiza nigaragara nkibikoresho byo hanze.Isahani yamabara yicyuma ikoreshwa nkibikoresho byo hanze, naho modulus isanzwe ikoreshwa mugushushanya.Nuburyo bwambere bwibisanzwe byimukanwa bisanzwe.Muri rusange isura ni nziza, ivanze nuburyo bwububiko bwumujyi wa Chengshi, kandi imikorere ni nziza.Isura yacyo yakemuye ikibazo cyo kubura imbaraga nke zurukuta rwo hanze rwinzu ya magnesium-fosifore, kandi ihita isimbuza inzu ya magnesium-fosifore yubatswe kandi ihinduka ubwoko busanzwe bwinzu yabugenewe.Ibi kandi bituma inzu yabugenewe irushaho gukoreshwa cyane, ntabwo ari amazu yigihe gito yubatswe
