I. Nga painga matua o XPS extruded putorino kiriweti kirihou
1. He pai te mahi whakawera waiariki
- Te iti o te wera o te waiariki: XPS te kawe waiariki o te 0.028 ~ 0.030 W / (mK), he iti ake i te EPS (0.045 W / (mK)) me te perlite ciment (0.12 W / (mK)). Hei tauira, he rite te 20mm te matotoru XPS te awe ki te 50mm te matotoru EPS me te 120mm te matotoru ciment perlite.
- Te reeti katinga teitei: ka eke te reiti katinga ki te neke atu i te 99%, ka hanga he paparanga korehau, he pai te aukati i te wera o te wera, te roa me te pumau o te mahi whakawera waiariki. Ko te polyurethane kua pahuka i te 80% anake.
2. Te kaha o te pupuhi
- Ko te awhe o te kaha compressive ko 150~700 kPa (i runga i te tauira me te matotoru), ka taea te tu ki te utaina o te whenua me te pai mo nga ahuatanga kaha teitei penei i nga huarahi me nga huarahi rererangi. Hei whakataurite, ko te kaha compressive EPS he 110~140 kPa anake.
3. He pai te whakakore i te wai me te makuku
- He iti ake i te 0.3% te tere o te whakauru wai, tata ki te kore e uru ki te wai, e whakaoti ana i te raruraru o te whakahekenga o te mahi tiaki wera o te EPS i muri i te tango i te wai, me te hukapapa iti-mahana e whakangaro ana i te hanganga. Ko te hanganga ngota polystyrene he pumau, kaore he waahi, hei karo i te pakaru o te wai, te hukapapa me etahi atu raruraru.
4. Te pumau mo te wa roa me te aukati waikura
- Matū pūmau, kore-pahekeheke, kore-poho, ora ratonga o runga ki te 30-60 tau (rerekētanga tukanga rerekē), te taiao pāmahana teitei tonu te mahi o te EPS he ngāwari ki te mimiti makuku degradation, he rawakore te ātete huarere.
5. Te taimaha marama me te hanga watea
- Ko te hanganga o te pūtau kati he maamaa me te kaha teitei, he ngawari ki te tapahi, ki te kawe me te whakauru, ka taea te hanga i te takurua, ko te EPS e hiahia ana kia kaha ake nga tikanga hanga na te iti o te kaha.
6. Te mahi taiao
- Te tango i nga rawa-a-taiao (hei tauira, te kaihoko pupuhi CO₂), kaore i te paitini me te kino, kaore he parahanga i roto i te mahi whakaputa, ka eke ki te whakamatautau a-motu. Ko etahi EPS kei roto pea te toenga Freon.

1. Te hokohoko ohaoha: Ahakoa he teitei ake te utu o te XPS i tera o te EPS, ka iti ake pea te utu matawhānui na te mea he angiangi te whakamahi matotoru me te roa o te oranga.
2. tono tukanga motuhake: pērā i te hanawiti prefabricated waiariki mātao waho pūnaha paewhiri o Yuanda Sumitomo, te XPS kua tukutahia ki te taiepa, kia rite ki te whakatutuki i te roa te roa o te waiariki marara me te whare, me te karo i te hanga tuarua.
3. mahi ahi: XPS mahi ngingiha ki runga ki te B1 (muara mura), engari me aro ki te rerekētanga tukanga i waenganui i kaihanga rerekē.
Ko te whakataurite o runga ake e whakaatu ana ko te XPS extruded plastic pipe insulation i roto i te mahi whakaahuru, te kaha, te mauroa me etahi atu waahanga o nga painga matawhānui he mea nui, ina koa mo te kawenga nui, te makuku nui, nga whakaritenga mo te oranga roa o te waahi.
