Waihanga-rua te paninga parewai
BiogoTMKo te paninga parewai-waahanga-rua no te whakakoi i nga rawa parewai, a ko te Rōpū A he isocyanate ka mutu i mua i te polymer polycondensated e te polyether me te isocyanate, ko te Rōpū B he wai tae he mea hanga ki te plasticizer, te rongoa rongoa, te whakapakeke, te kaihoko coagulant me te whakakii, ,ix Rōpū Ko te A me te B ka rite ki te reiti me te parai i runga i te mata tïpako parewai, hanga he kiriata whakakikorua me te rapa-rite ki te rapa ma te hono-whakawhiti me te whakakoi i te pāmahana noa, he mahi parewai.
Te ahuatanga
l BiogoTMKo te paninga parewai-waahanga-rua ka hangai korekore, whakauru i te elasticity paparanga parewai whakakorikori, me te whakapai ake i te parewai me te atete o te kaupapa, he membrane parewai e kore e taea te whakatutuki.Ina koa ko te kiriata paninga he elasticity teitei me te elongation, teitei te urutau ki te pakaru o te tïpako, te roha ranei.
l Maamaa te hononga ki te tïpako, ko te kiriata paninga he kaha te hono ki te raima, te rakau, te konganuku, te uku me te kirikiri asbestos, ka taea hoki te whakamahi hei here.
l tono watea, polyurethane paninga kiriata ko te tono matao paninga parewai, uru tika rōpū A me B rite reiti ka tono me te parai i runga i te tïpako parewai.
l Te tiaki ngawari, te pupuri noa i nga waahanga pakaru, ka tae ki nga paanga taketake o te parewai, te whakaora i te wa, te whakaora i te mana me te utu iti.
l Hua taiao, me te whakaiti i te kino o te tangata me te taiao.
Te whānuitanga e tika ana
Ka whakamahia nuitia i roto i nga tuanui, i raro, i te puna kaukau, me nga momo umanga katoa me te whakamaarama i te whare tangata.

Hangarau tono
l Me u te papapa, kia maeneene, kia kore he maha, ko te kokonga o roto me te kokonga o waho me hanga hei pewa porohita, kia neke ake i te 50mm te diameter o te kokonga o roto, me te taura o waho.
l Me nui ake i te 10mm.;
Te whakauru me te inenga: kia rite ki te inenga tono, kia rite te whakaranu ki a tatou.
l inenga tohutoro;paninga kiriata inenga ko e pā ana ki 1.3-1.5kg / sqm ina he 1mm te matotoru.
Ko te tono parewai nui, te paninga orite te paninga i konatunatua ki te rapa, ki te kirikiri kirihou ranei, ka mau tonu te matotoru, ko te tikanga he 1.5mm ki te 2.0mm, me parai kia 3 ki te 4 nga wa, ko te wa whakamutunga ka parai i muri i nga rongoa o te parai. a ka huri hei kiriata, ka parai i te huarahi kore.Ko te tikanga hei hanga kiriata motuhake, mo te papa kaupapa o raro o te whenua, me wharikihia he paparanga o nga rawa whakakaha hei taapiri.
Te matotoru paninga: Ki te matotoru kaupapa o raro he 1.2 ki te 2.0mm, te tikanga 1.5mm;ki te matotoru wharepaku kaua e iti iho i te 1.5mm;ki multilayer parewai o te matotoru hanga tuanui e kore e iti iho i te 1.2,,;ki tetahi paparanga parewai o te karaehe Ⅲ parewai, kaua e iti iho i te 2mm te matotoru;
Whakaoti tono paparanga: whakamararatia te onepu kua horoia i mua i te wa whakamutunga ka kore te parai kia pakari.
Paparanga Tiaki: i runga i te mata o te kiriata paninga me mahi te whakamarumaru whakamarumaru hei hoahoa.
Te aro
l Karekau e taea te waimeha te waikawa waipiro, te waimeha nitro penei i te peita angiangi, kaua e pa ki te wai.
l Puritia te hau hau, mo te ahi.
l Mena he iti te ahua o te rauemi, me whakakotahi i mua i te whakamahi
l Ko te waahi hanga me pupuri i te hau pai, kaua hoki e pa ki te ra ua;
l Whakatuwheratia te uhi ka whakamahia, me whakamahi i roto i te 40 meneti;
l Mena ka kitea he kiriata paninga pakaru i te waahi hanga, keria huri noa i te tuwhera pakaru me te maripi tapahi, katahi ka parai i te paninga parewai me te whakatika.
Te rokiroki me nga taonga aro
l Puritia nga taonga ki roto i te ruuma kua maroke me te whai hau
l A ape i te ra tika i te wa e kawe ana, karohia nga tukinga me te aro ki te ahi
l Ko te wa taurangi mo te rokiroki he ono marama, me whakamahi te paninga o te wa rokiroki i muri i te tirotiro ano
