決定玻璃鋼水箱質量的要素
發布日期:2023年02月08日
    玻(bo)璃鋼(gang)模壓(ya)水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)是由SMC模壓(ya)板塊、密封材料、金屬結構(gou)件及配(pei)管系統現場(chang)組(zu)裝而(er)成。給設(she)計(ji)和施(shi)工帶來很大(da)方便(bian)(bian)。一般(ban)水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)按標準設(she)計(ji),水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)需(xu)要(yao)(yao)設(she)計(ji)。可根據(ju)用(yong)戶(hu)需(xu)要(yao)(yao)組(zu)裝0.125-1500立(li)方米的水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)。若(ruo)原有水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)需(xu)要(yao)(yao)換,不需(xu)要(yao)(yao)改造房屋,適(shi)應(ying)性很強。研(yan)制的定型產品密封帶,該密封帶、耐(nai)(nai)水(shui)(shui)(shui)、彈性大(da)、變型小,緊固(gu)密封。水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)整體(ti)強度高(gao),無滲漏,無變形,保養(yang)、檢修方便(bian)(bian)。 玻(bo)璃鋼(gang)水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)是目(mu)前(qian)采用(yong)的新型水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)。由整體(ti)SMC水(shui)(shui)(shui)箱(xiang)(xiang)(xiang)板拼裝而(er)成。其特點是采用(yong)食品樹脂,因此水(shui)(shui)(shui)質好;具有強度高(gao),重量(liang)輕(qing),耐(nai)(nai)腐蝕(shi),外型美(mei)觀,使用(yong)時(shi)間長,保養(yang)管理方便(bian)(bian)等特點。
    決定玻璃鋼模壓水(shui)箱(xiang)質(zhi)量的三(san)項要素
    一、合成樹脂
    合成(cheng)(cheng)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)是決(jue)(jue)定玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)鋼(gang)水箱(xiang)質量(liang)(liang)(liang)(liang)基體(ti)材(cai)料(liao),松散(san)的(de)玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)纖維靠它粘(zhan)接(jie)成(cheng)(cheng)整體(ti),主 要(yao)(yao)起(qi)傳遞(di)應力作(zuo)用,因此樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)對玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)鋼(gang)水箱(xiang)質量(liang)(liang)(liang)(liang)中的(de)強度起(qi)重要(yao)(yao)作(zuo)用,抗壓(ya)、彎曲、扭轉、剪切強度。 樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)對玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)鋼(gang)水箱(xiang)性(xing)(xing)(xing)能也(ye)有影(ying)響(xiang),通(tong)常(chang)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)為20%-35%,這和(he)成(cheng)(cheng)型(xing)(xing)方法(fa)、材(cai)料(liao)品(pin)種(zhong)有關。例(li)如(ru),纏(chan)繞(rao)和(he)模壓(ya)成(cheng)(cheng)型(xing)(xing),樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)偏(pian)低(di),而手糊成(cheng)(cheng)型(xing)(xing)、樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)則(ze)稍(shao)高。強度層樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)稍(shao)低(di),通(tong)常(chang)可(ke)在25%-40%之間;耐(nai)腐蝕(shi)、不滲層樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)較高,一般(ban)要(yao)(yao)過50%用玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)布(bu)作(zuo)材(cai)料(liao),樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)低(di)于用玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)氈。用玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)纖維表(biao)面氈作(zuo)材(cai)料(liao)時,可(ke)達85%的(de)富(fu)樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)含(han)量(liang)(liang)(liang)(liang)。  此外,樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)是決(jue)(jue)定玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)鋼(gang)水箱(xiang)品(pin)質的(de)基體(ti)材(cai)料(liao),它對玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)鋼(gang)的(de)彈(dan)性(xing)(xing)(xing)模量(liang)(liang)(liang)(liang)、耐(nai)熱性(xing)(xing)(xing)、不導(dao)電、透電磁(ci)波性(xing)(xing)(xing)、耐(nai)化(hua)學(xue)腐蝕(shi)性(xing)(xing)(xing)、耐(nai)氣候性(xing)(xing)(xing)、耐(nai)老化(hua)性(xing)(xing)(xing)等都有影(ying)響(xiang)。例(li)如(ru)玻(bo)(bo)(bo)璃(li)(li)(li)(li)(li)鋼(gang)的(de)耐(nai)化(hua)學(xue)液體(ti)浸蝕(shi)性(xing)(xing)(xing)和(he)耐(nai)水性(xing)(xing)(xing),主要(yao)(yao)取決(jue)(jue)于樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)基體(ti)的(de)性(xing)(xing)(xing)能。通(tong)常(chang)不飽(bao)和(he)聚(ju)酯樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)197#耐(nai)化(hua)學(xue)腐蝕(shi)較好,而1289#耐(nai)水較好。不同(tong)(tong)類型(xing)(xing)、不同(tong)(tong)牌號樹(shu)(shu)(shu)脂(zhi)(zhi)(zhi)其性(xing)(xing)(xing)能是不相同(tong)(tong)的(de)。
    二、玻璃纖維
    玻(bo)璃(li)纖(xian)維是決定(ding)玻(bo)璃(li)鋼水箱質量的(de)主要(yao)承力部分(fen),它能夠(gou)讓玻(bo)璃(li)鋼的(de)強(qiang)度(du)(du)和(he)彈性模量,而且能夠(gou)減少(shao)收縮變形,熱變形溫(wen)度(du)(du)和(he)低溫(wen)沖(chong)擊強(qiang)度(du)(du)等。例如(ru)306#聚酯樹脂澆(jiao)鑄體(ti),在加入50%的(de)玻(bo)璃(li)布(bu)后。拉伸(shen)強(qiang)度(du)(du)可(ke)由(you)(you)50MPa到200MPa,拉伸(shen)模量可(ke)由(you)(you)3.9GPa到14GPa.
    三、界面 
    所謂界(jie)面就是(shi)兩相物質間(jian)的分界(jie)面。  
    玻(bo)璃(li)鋼水箱(xiang)質量與所用(yong)的材料、合成樹脂(zhi)(zhi)有關,同(tong)時(shi),還和纖維與樹脂(zhi)(zhi)之間界面粘合的好壞及耐久性(xing)有關。  
    眾所周(zhou)知,玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)是(shi)(shi)(shi)(shi)一(yi)(yi)(yi)種圓柱(zhu)狀玻(bo)(bo)(bo)(bo)(bo)璃(li)(li),表(biao)面(mian)也象玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)那樣光滑,而(er)且表(biao)面(mian)還常(chang)地(di)吸附著一(yi)(yi)(yi)層(ceng)(ceng)薄(bo)的(de)(de)(de)水(shui)膜,這當然要影(ying)響(xiang)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)和樹(shu)脂的(de)(de)(de)粘接性能。玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)在(zai)拉絲紡(fang)織過程(cheng)中,為(wei)了達到集(ji)束、潤滑、靜電等目(mu)的(de)(de)(de),常(chang)涂上(shang)一(yi)(yi)(yi)層(ceng)(ceng)浸潤劑(ji),這種浸潤劑(ji)多數是(shi)(shi)(shi)(shi)石蠟類物(wu)質(zhi)(zhi),它們(men)存留(liu)在(zai)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)表(biao)面(mian)上(shang),對(dui)(dui)合(he)(he)成樹(shu)脂與玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)起作用(yong),妨礙兩(liang)者粘接。可(ke)(ke)見界面(mian)對(dui)(dui)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)的(de)(de)(de)性能影(ying)響(xiang)很大。如(ru)在(zai)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)表(biao)面(mian)覆蓋(gai)一(yi)(yi)(yi)層(ceng)(ceng)表(biao)面(mian)處理劑(ji),從而(er)使玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)和樹(shu)脂可(ke)(ke)以(yi)地(di)粘接在(zai)一(yi)(yi)(yi)起。這種方法是(shi)(shi)(shi)(shi)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)水(shui)箱質(zhi)(zhi)量很途徑,外(wai)都在(zai)研究和采用(yong)。實踐證(zheng)明(ming),玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)及(ji)其織物(wu),在(zai)經過表(biao)面(mian)處理劑(ji)處理后,玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)的(de)(de)(de)耐(nai)水(shui)、不導電,對(dui)(dui)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)水(shui)箱質(zhi)(zhi)量的(de)(de)(de)強(qiang)度,是(shi)(shi)(shi)(shi)潮濕情(qing)況下的(de)(de)(de)強(qiang)度。由此(ci)可(ke)(ke)見,影(ying)響(xiang)玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)鋼(gang)組(zu)合(he)(he)水(shui)箱質(zhi)(zhi)量的(de)(de)(de)因素,除了玻(bo)(bo)(bo)(bo)(bo)璃(li)(li)纖(xian)(xian)(xian)維(wei)和樹(shu)脂這兩(liang)大組(zu)分之(zhi)外(wai),界面(mian)也是(shi)(shi)(shi)(shi)重要的(de)(de)(de)。這三(san)大要素,它們(men)之(zhi)間(jian)是(shi)(shi)(shi)(shi)密(mi)切關聯(lian)的(de)(de)(de),不可(ke)(ke)分割(ge)。
