新式大棚:溫(wen)室(shi)(shi)(shi)的(de)透(tou)光(guang)覆(fu)蓋(gai)材(cai)料主要指其(qi)透(tou)光(guang)面材(cai)料,根據其(qi)材(cai)料的(de)不(bu)同(tong)可以(yi)把溫(wen)室(shi)(shi)(shi)劃分(fen)為玻璃溫(wen)室(shi)(shi)(shi)、硬質(zhi)板塑(su)料溫(wen)室(shi)(shi)(shi)、塑(su)料薄(bo)膜(mo)溫(wen)室(shi)(shi)(shi)和其(qi)他覆(fu)蓋(gai)材(cai)料溫(wen)室(shi)(shi)(shi)等。
1.玻(bo)(bo)(bo)璃溫(wen)(wen)室(shi)(shi) 玻(bo)(bo)(bo)璃溫(wen)(wen)室(shi)(shi)是以(yi)玻(bo)(bo)(bo)璃為(wei)主要透光(guang)覆(fu)蓋(gai)材(cai)料(liao)(liao)的(de)(de)溫(wen)(wen)室(shi)(shi),有單層(ceng)(ceng)玻(bo)(bo)(bo)璃溫(wen)(wen)室(shi)(shi)和(he)雙(shuang)層(ceng)(ceng)中空玻(bo)(bo)(bo)璃溫(wen)(wen)室(shi)(shi)。作為(wei)溫(wen)(wen)室(shi)(shi)覆(fu)蓋(gai)的(de)(de)玻(bo)(bo)(bo)璃主要為(wei)5mm厚或4mm厚的(de)(de)平板玻(bo)(bo)(bo)璃,其保溫(wen)(wen)性能介于塑料(liao)(liao)薄膜和(he)PC板之間,透光(guang)性較(jiao)好。玻(bo)(bo)(bo)璃溫(wen)(wen)室(shi)(shi)所需(xu)要的(de)(de)材(cai)料(liao)(liao)和(he)配件(jian)價格較(jiao)高(gao),而且玻(bo)(bo)(bo)璃質量大(da),對溫(wen)(wen)室(shi)(shi)骨(gu)架(jia)負荷(he)要求高(gao),骨(gu)架(jia)的(de)(de)用量也(ye)就相(xiang)應增加(jia),所以(yi)總體溫(wen)(wen)室(shi)(shi)的(de)(de)造價較(jiao)高(gao)。
2.硬質(zhi)板(ban)(ban)(ban)塑(su)料(liao)(liao)溫(wen)室(shi) 硬質(zhi)板(ban)(ban)(ban)塑(su)料(liao)(liao)溫(wen)室(shi)是以(yi)硬質(zhi)板(ban)(ban)(ban)塑(su)料(liao)(liao)為透光覆蓋材(cai)料(liao)(liao)的溫(wen)室(shi)。硬質(zhi)板(ban)(ban)(ban)材(cai)料(liao)(liao)包括聚碳(tan)酸酯中空板(ban)(ban)(ban)(PC板(ban)(ban)(ban))、聚氯乙(yi)烯板(ban)(ban)(ban)(PVC板(ban)(ban)(ban))、玻(bo)(bo)璃纖(xian)維增(zeng)強塑(su)料(liao)(liao)板(ban)(ban)(ban)(FRP)和玻(bo)(bo)璃纖(xian)維增(zeng)強丙烯酸樹脂(zhi)板(ban)(ban)(ban)等(deng)。硬質(zhi)板(ban)(ban)(ban)塑(su)料(liao)(liao)質(zhi)量輕、便于運輸、安裝和維護,是目前采用較(jiao)為廣泛的一種材(cai)料(liao)(liao)。
3.塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi) 用(yong)(yong)塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)為(wei)(wei)覆(fu)(fu)蓋(gai)材料(liao)(liao)(liao)(liao)(liao)的溫(wen)(wen)(wen)(wen)室(shi)(shi)稱為(wei)(wei)塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi)。塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)為(wei)(wei)軟質輕型(xing)材料(liao)(liao)(liao)(liao)(liao),塑料(liao)(liao)(liao)(liao)(liao)溫(wen)(wen)(wen)(wen)室(shi)(shi)的承重結構(gou)、固膜(mo)(mo)(mo)(mo)系統、安裝(zhuang)要求等比較(jiao)簡(jian)單。塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi)根據體型(xing)大(da)小(xiao)又可以分為(wei)(wei)塑料(liao)(liao)(liao)(liao)(liao)中小(xiao)拱棚(peng)、塑料(liao)(liao)(liao)(liao)(liao)大(da)棚(peng)和大(da)型(xing)塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi)。為(wei)(wei)增強塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi)的保溫(wen)(wen)(wen)(wen)性(xing)能,也采用(yong)(yong)雙層塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)覆(fu)(fu)蓋(gai),根據覆(fu)(fu)蓋(gai)的層數可以分為(wei)(wei)單層塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi)和雙層塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)溫(wen)(wen)(wen)(wen)室(shi)(shi)。常用(yong)(yong)的塑料(liao)(liao)(liao)(liao)(liao)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)有(you)聚(ju)乙(yi)烯(xi)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)(PE)、聚(ju)氯乙(yi)烯(xi)薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)(PVC)、聚(ju)乙(yi)烯(xi)無滴(di)長(chang)壽膜(mo)(mo)(mo)(mo)、聚(ju)氯乙(yi)烯(xi)無滴(di)長(chang)壽膜(mo)(mo)(mo)(mo)、彩色薄(bo)(bo)(bo)膜(mo)(mo)(mo)(mo)等。
