陶粒的介紹

陶(tao)(tao)(tao)(tao)粒(li)(li)填料(liao)(liao)(liao)的開發研究(jiu)陶(tao)(tao)(tao)(tao)粒(li)(li)的概念陶(tao)(tao)(tao)(tao)粒(li)(li)是以(yi)粘(zhan)土(tu)(tu)(tu)(tu)、頁巖(yan)、煤(mei)研石、粉(fen)煤(mei)灰等(deng)(deng)為(wei)(wei)主(zhu)要原(yuan)(yuan)料(liao)(liao)(liao)，摻加(jia)(jia)少量粘(zhan)結劑(ji)、附(fu)加(jia)(jia)劑(ji)等(deng)(deng)經(jing)加(jia)(jia)工成粒(li)(li)或(huo)粉(fen)磨成球，再經(jing)燒(shao)脹等(deng)(deng)工藝制(zhi)成的一種人造(zao)輕(qing)(qing)型骨(gu)料(liao)(liao)(liao)。頁巖(yan)陶(tao)(tao)(tao)(tao)粒(li)(li)外(wai)表堅(jian)硬，里面(mian)(mian)遍布小孔。粒(li)(li)徑在2mm-20mm之間。一般而(er)言(yan)，普通陶(tao)(tao)(tao)(tao)粒(li)(li)比表面(mian)(mian)積為(wei)(wei)300-1000m2/m3、堆(dui)積密(mi)度為(wei)(wei)200-1000kg/m3、孔隙率達到30%以(yi)上。早期的陶(tao)(tao)(tao)(tao)粒(li)(li)大多采用(yong)頁巖(yan)直(zhi)接燒(shao)制(zhi)而(er)成，為(wei)(wei)不規則狀。近來出現的球形輕(qing)(qing)質陶(tao)(tao)(tao)(tao)粒(li)(li)，大多采用(yong)粘(zhan)土(tu)(tu)(tu)(tu)為(wei)(wei)主(zhu)要原(yuan)(yuan)料(liao)(liao)(liao)，添加(jia)(jia)適當(dang)的化(hua)工原(yuan)(yuan)料(liao)(liao)(liao)做膨脹劑(ji)，經(jing)過高(gao)溫燒(shao)制(zhi)而(er)成。黏土(tu)(tu)(tu)(tu)陶(tao)(tao)(tao)(tao)粒(li)(li)因為(wei)(wei)其(qi)燒(shao)制(zhi)原(yuan)(yuan)料(liao)(liao)(liao)是黏土(tu)(tu)(tu)(tu)的原(yuan)(yuan)因，現在被廣(guang)泛(fan)應用(yong)與無土(tu)(tu)(tu)(tu)栽培和花(hua)卉種植方面(mian)(mian)。陶(tao)(tao)(tao)(tao)粒(li)(li)的分(fen)類(lei):按原(yuan)(yuan)料(liao)(liao)(liao)分(fen)類(lei)：粘(zhan)土(tu)(tu)(tu)(tu)陶(tao)(tao)(tao)(tao)粒(li)(li)、粉(fen)煤(mei)灰陶(tao)(tao)(tao)(tao)粒(li)(li)、頁巖(yan)陶(tao)(tao)(tao)(tao)粒(li)(li)、煤(mei)研石陶(tao)(tao)(tao)(tao)粒(li)(li)等(deng)(deng)。3.2.2 按擴散(san)容(rong)(rong)重(zhong)分(fen)：一般容(rong)(rong)重(zhong)陶(tao)(tao)(tao)(tao)粒(li)(li)，容(rong)(rong)重(zhong)大于500kg/m3；超(chao)輕(qing)(qing)容(rong)(rong)重(zhong)陶(tao)(tao)(tao)(tao)粒(li)(li)，容(rong)(rong)重(zhong)為(wei)(wei)200~500kg/m3；容(rong)(rong)重(zhong)200kg/m3。

按(an)加工(gong)形(xing)狀分：圓球形(xing)陶(tao)粒和(he)普通型(xing)陶(tao)粒。按(an)傳統(tong)的(de)(de)(de)(de)(de)(de)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)產工(gong)藝(yi)分：燒結型(xing)，以(yi)粘(zhan)土、頁巖為主(zhu)要(yao)(yao)原料；燒脹型(xing)，以(yi)粉煤灰為主(zhu)要(yao)(yao)原料等。再(zai)說(shuo)陶(tao)粒在(zai)(zai)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜的(de)(de)(de)(de)(de)(de)應(ying)用(yong)方面(mian)的(de)(de)(de)(de)(de)(de)分析：生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜在(zai)(zai)填料上形(xing)成的(de)(de)(de)(de)(de)(de)關鍵是(shi)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)在(zai)(zai)載(zai)體(ti)(ti)表(biao)(biao)(biao)(biao)面(mian)的(de)(de)(de)(de)(de)(de)固定情況。微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)在(zai)(zai)載(zai)體(ti)(ti)表(biao)(biao)(biao)(biao)面(mian)附(fu)(fu)著(zhu)(zhu)(zhu)并(bing)實(shi)現(xian)(xian)固定化是(shi)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)表(biao)(biao)(biao)(biao)面(mian)與載(zai)體(ti)(ti)表(biao)(biao)(biao)(biao)面(mian)之間(jian)的(de)(de)(de)(de)(de)(de)相(xiang)互作用(yong)。這種相(xiang)互作用(yong)的(de)(de)(de)(de)(de)(de)過(guo)程與微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)自身特(te)性(xing)(xing)有(you)關，同時(shi)也與固定載(zai)體(ti)(ti)的(de)(de)(de)(de)(de)(de)物(wu)(wu)(wu)理(li)化學特(te)性(xing)(xing)及環境因素（如pH值、離子強度、水(shui)(shui)力剪切力、溫度等）密切相(xiang)關。微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)向(xiang)載(zai)體(ti)(ti)表(biao)(biao)(biao)(biao)面(mian)的(de)(de)(de)(de)(de)(de)輸(shu)送(song)有(you)主(zhu)動(dong)運(yun)輸(shu)和(he)被動(dong)運(yun)輸(shu)兩種方式，其中主(zhu)動(dong)運(yun)輸(shu)起(qi)著(zhu)(zhu)(zhu)主(zhu)導的(de)(de)(de)(de)(de)(de)作用(yong)。微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)轉移到(dao)載(zai)體(ti)(ti)表(biao)(biao)(biao)(biao)面(mian)后，首先形(xing)成的(de)(de)(de)(de)(de)(de)是(shi)可(ke)(ke)逆(ni)附(fu)(fu)著(zhu)(zhu)(zhu)。可(ke)(ke)逆(ni)附(fu)(fu)著(zhu)(zhu)(zhu)實(shi)際上是(shi)一個附(fu)(fu)著(zhu)(zhu)(zhu)與解(jie)析的(de)(de)(de)(de)(de)(de)雙向(xiang)動(dong)態(tai)過(guo)程。不(bu)可(ke)(ke)逆(ni)附(fu)(fu)著(zhu)(zhu)(zhu)是(shi)指(zhi)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)在(zai)(zai)可(ke)(ke)逆(ni)附(fu)(fu)著(zhu)(zhu)(zhu)過(guo)程中分泌的(de)(de)(de)(de)(de)(de)粘(zhan)性(xing)(xing)代謝(xie)產物(wu)(wu)(wu)牢牢地(di)粘(zhan)封在(zai)(zai)載(zai)體(ti)(ti)表(biao)(biao)(biao)(biao)面(mian)，使得(de)附(fu)(fu)著(zhu)(zhu)(zhu)過(guo)程成為不(bu)可(ke)(ke)逆(ni)。不(bu)可(ke)(ke)逆(ni)附(fu)(fu)著(zhu)(zhu)(zhu)是(shi)微(wei)(wei)(wei)生(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)(sheng)物(wu)(wu)(wu)膜群落的(de)(de)(de)(de)(de)(de)基礎。這個特(te)性(xing)(xing)就決定了陶(tao)粒在(zai)(zai)水(shui)(shui)處理(li)和(he)作為濾料方面(mian)有(you)著(zhu)(zhu)(zhu)得(de)天獨厚的(de)(de)(de)(de)(de)(de)優勢，而陶(tao)粒的(de)(de)(de)(de)(de)(de)更多的(de)(de)(de)(de)(de)(de)使用(yong)方法正在(zai)(zai)被逐步(bu)發現(xian)(xian)。

陶(tao)(tao)粒(li)除了(le)(le)具有多(duo)孔、輕重、表面強度高(gao)等(deng)物理(li)性能(neng)外，在(zai)生(sheng)產(chan)(chan)過程中(zhong)(zhong)還使(shi)其具有了(le)(le)一定(ding)的(de)活性物質，因(yin)而已開始(shi)用(yong)(yong)(yong)于與日常(chang)生(sheng)活有關的(de)飲水(shui)(shui)、洗浴(yu)等(deng)方面來(lai)，如過放(fang)在(zai)飲水(shui)(shui)機中(zhong)(zhong)過濾(lv)飲用(yong)(yong)(yong)水(shui)(shui)、放(fang)在(zai)淋浴(yu)花(hua)灑(sa)的(de)手柄(bing)中(zhong)(zhong)增(zeng)加水(shui)(shui)的(de)活性等(deng)。所以(yi)陶(tao)(tao)粒(li)也常(chang)見于自來(lai)水(shui)(shui)廠(chang)及污水(shui)(shui)處理(li)廠(chang)。陶(tao)(tao)粒(li)濾(lv)料由于具有較高(gao)的(de)比(bi)表面積，化(hua)學(xue)和(he)熱(re)穩定(ding)性好，價格低廉因(yin)此得到了(le)(le)廣(guang)泛(fan)的(de)應(ying)用(yong)(yong)(yong)。建(jian)(jian)筑陶(tao)(tao)粒(li)在(zai)應(ying)用(yong)(yong)(yong)方面是毋庸(yong)置疑的(de)的(de)受到建(jian)(jian)筑商家的(de)好品(pin)和(he)贏得消費者的(de)肯定(ding)，產(chan)(chan)品(pin)突出的(de)特點，作(zuo)為一種新型材料，因(yin)其具有重量輕、強度高(gao)、導熱(re)系數(shu)小、吸水(shui)(shui)率小、耐(nai)高(gao)溫、抗老(lao)化(hua)、耐(nai)酸堿、無放(fang)射性、環保節能(neng)等(deng)特點而在(zai)建(jian)(jian)筑領域中(zhong)(zhong)得到廣(guang)泛(fan)的(de)應(ying)用(yong)(yong)(yong)。在(zai)此同時，陶(tao)(tao)粒(li)也被(bei)應(ying)用(yong)(yong)(yong)與社會(hui)的(de)方方面面。
