護(hu)木(mu)架合金管用于晉(jin)安區(qu)園林局(ju)

光亮度高(gao)，適用于掛(gua)鍍(du)(du)鋅和滾鍍(du)(du)鋅生產中(zhong)合金(jin)管鍍(du)(du)層柔軟。容易進(jin)行鉻(ge)酸鹽鈍化有(you)市民(min)發現，晉(jin)安(an)(an)(an)北路，已安(an)(an)(an)裝了(le)(le)200多(duo)個合金(jin)管護(hu)(hu)木(mu)(mu)架(jia)。園林專家告訴記者，每年(nian)福州遭遇臺風，晉(jin)安(an)(an)(an)北路的樹木(mu)(mu)特別容易倒伏。這是(shi)因(yin)為早先種(zhong)(zhong)樹時，土層較(jiao)薄(bo)。今年(nian)秋季，15CrMoG合金(jin)管晉(jin)安(an)(an)(an)區園林局開始重(zhong)新(xin)種(zhong)(zhong)植行道樹，采用胸徑(jing)15厘米、四五(wu)米高(gao)的香樟(zhang)樹。為了(le)(le)保護(hu)(hu)樹苗，本月，晉(jin)安(an)(an)(an)區園林局給它配備了(le)(le)合金(jin)管護(hu)(hu)木(mu)(mu)架(jia)。昨日(ri)，記者在晉(jin)安(an)(an)(an)北路尋(xun)訪(fang)，看到超過(guo)200棵(ke)新(xin)種(zhong)(zhong)大樹安(an)(an)(an)裝上(shang)了(le)(le)這種(zhong)(zhong)兩米多(duo)高(gao)的護(hu)(hu)木(mu)(mu)架(jia)。

這些(xie)護木(mu)架是將四根合(he)(he)金管(guan)(guan)(guan)用(yong)鐵環(huan)串起，箍(gu)在大樹的腰部，合(he)(he)金管(guan)(guan)(guan)鐵環(huan)和(he)支架的連(lian)接(jie)處用(yong)螺絲擰緊，并(bing)進行焊接(jie)。說(shuo)到使(shi)用(yong)合(he)(he)金管(guan)(guan)(guan)護木(mu)架的優點，合(he)(he)金管(guan)(guan)(guan)參與晉安北路道路設計(ji)的羅(luo)先生說(shuo)，杉木(mu)和(he)竹條材質，二者使(shi)用(yong)壽命大約在一到兩年，比較容(rong)(rong)易被破壞，合(he)(he)金管(guan)(guan)(guan)材質的護木(mu)架則(ze)比較結實。寬廣的電(dian)流密度范(fan)圍(wei)內都(dou)可以得到光亮的鍍鋅層適用(yong)于低氰化(hua)物(wu)鍍鋅，減少環(huan)境(jing)污染工藝范(fan)圍(wei)廣，容(rong)(rong)易操(cao)作控制合(he)(he)金管(guan)(guan)(guan)大部分氰化(hua)鍍鋅工藝可直接(jie)補充此光亮劑(ji)，進行轉(zhuan)缸(gang)
