Nyumba ya prefab idagwiritsidwa ntchito ngati malo ogona osakhalitsa pamalo omanga ndipo idachokera ku Guangdong.Pambuyo pa kukonzanso ndi kutsegulidwa, Shenzhen, monga malo oyendetsa ndege kuti asinthe ndi kutsegulira, ankafunika mwamsanga kumanga nyumba zosiyanasiyana, ndipo omangamanga ndi ogwira ntchito zomangamanga adatsanulira ku Shenzhen kuchokera kudziko lonse.Pofuna kuthetsa vuto la malo okhala antchito, okonza mapulani akhazikitsa malo ogona osakhalitsa.Nyumba zosakhalitsa pamalo omangawo poyamba inali nyumba yosakhalitsa yomangidwa ndi matailosi a asbestos monga pamwamba pake.Ngakhale mtengo wake unali wotsika, poyerekeza ndi nyumba zomangidwa pambuyo pake, zinali zophweka komanso zinali ndi chitetezo chochepa, ndipo kwenikweni zinalibe mphepo ndi kugwedezeka.Pambuyo pa zaka za m'ma 1990, dzikoli linalimbitsa kasamalidwe ka malo omanga kuti atsimikizire chitetezo cha ogwira ntchito;asibesitosi adatsimikiziridwanso kuti ndi chinthu chovulaza komanso choyambitsa khansa.Mzinda wa Shenzhen umaletsa momveka bwino kugwiritsa ntchito matailosi a asibesito kuti amange nyumba zogona zosakhalitsa, ndipo nyumba zogona zosakhalitsa ziyenera kukhala ndi chitetezo china, chopanda mphepo komanso kugwedezeka.Ziletso zakhazikitsidwanso m'dziko lonselo.Izi zimatsogolera mwachindunji kupanga nyumba zopangira prefab zokhala ndi matayala a PU ngati matayala apadenga.
M'masiku oyambilira, panalibe yunifolomu komanso yogwirizana yomanga nyumba za prefab.Motsatira nthawi, nyumba za prefab zitha kugawidwa m'magulu atatu:
1. Nyumba yopangira simenti.
Nyumba zosakhalitsa pamalo omangira oyambilira zimamangidwa ndi magulu omanga okha.Nyumba zosakhalitsa zomangidwa, zokhala ndi mawonekedwe apamwamba kwambiri, ziyenera kukhala zokhala ndi makoma a simenti monga gawo lalikulu.Matailosi a asbestos ataletsedwa, matailosi a PU adagwiritsidwa ntchito mwachindunji m'malo mwake.Iyi ndiye nyumba yoyambirira kwambiri: nyumba yopangira simenti.Komabe, nyumba ya prefab ya simenti sikuyenda.Ngakhale kuti zipangizo zomangirazo zimagwiritsidwa ntchito mwachindunji, nthawi yomangayo ndi yaitali ndipo mtengo wake ndi wokwera.Ntchitoyo ikamalizidwa, zimakhala zovuta kugwetsa nyumba ya simenti, yomwe imawononga anthu ambiri komanso zinthu zakuthupi;sichingasinthidwenso.
2. Magnesium ndi phosphorous zosunthika chipinda bolodi.
Magnesium-phosphorous prefab house ndi nyumba yeniyeni ya prefab, yogwiritsira ntchito bolodi la magnesium-phosphorous ngati khoma komanso chitsulo chopepuka ngati mafupa a board board.Ubwino wa kapangidwe kazitsulo zopepuka umazindikirika pang'onopang'ono ndi anthu.Tekinoloje ya msonkhano wa board house ikukulanso.Miyezo yopangira ndi kukhazikitsa nyumba za prefab imapangidwa pang'onopang'ono.Koma ndi maonekedwe a mtundu zitsulo prefab nyumba, magnesium phosphorous prefab nyumba wakhala chinthu kusintha.
3. Mtundu zitsulo prefab nyumba.
Magnesium-phosphorous board ndi yopepuka komanso yocheperako, ndipo magwiridwe ake osalowa madzi komanso osayaka moto sangafanane ndi mbale yachitsulo yamtundu wa EPS.Posakhalitsa, anthu adapeza kuti bolodi la magnesium-phosphorous siliyenera ngati khoma lakunja, koma loyenera ngati khoma lamkati.Choncho anayamba kugwiritsa ntchito mtundu zitsulo mbale ndi ntchito kwambiri ndi maonekedwe ngati kunja khoma zakuthupi.Mbalame yachitsulo yamtundu imagwiritsidwa ntchito ngati zida zakunja zakunja, ndipo modulus yokhazikika imagwiritsidwa ntchito popanga.Awa ndi mawonekedwe oyambilira a mbale yaposachedwa yosunthika.Maonekedwe onse ndi okongola, osakanikirana ndi kamangidwe ka mzinda wa Chengshi, ndipo machitidwe ake ndi abwinoko.Maonekedwe ake anathetsa kusowa kwa mphamvu yotsika ya khoma lakunja la magnesium-phosphorous-prefabricated house, ndipo mwamsanga m'malo mwa magnesium-phosphorous prefabricated nyumba ndipo anakhala mtundu muyezo wa nyumba prefabricated.Izi zimapangitsanso kuti nyumba yomangidwa kale ikhale yogwiritsidwa ntchito kwambiri, osati ngati nyumba zosakhalitsa pomanga
