deep brown - brown-black;Occupational acne;Verrucous vegetations and the accident cause thermal burns.In addition, there are dizziness, head bilges, headache, chest tightness, fatigue, nausea, loss of appetite and other systemic symptom and eye, nose, pharynx and irritation. 煤焦瀝(lì)青Coal tar 煤焦(jiao)瀝青是(shì)煉焦的(de)副産品(pǐn)，即焦油(yóu)蒸餾後(hòu)殘留在(zai)蒸餾釜(fu)内的黑(hēi)色物質(zhì)。它與精(jīng)制焦油(you)隻是物(wù)理性質(zhi)有分别(bie)，沒有明(míng)顯的界(jiè)限，一般(ban)的劃分(fèn)方法是(shi)規定軟(ruan)化點在(zài)26．7℃（立方塊(kuai)法）以下(xià)的為焦(jiāo)油，26．7℃以上(shàng)的為瀝(li)青。煤焦(jiāo)瀝青中(zhōng)主要含(hán)有難揮(hui)發的蒽(en)、菲、芘等(děng)。這些物(wù)質具有(yǒu)毒性，由(yóu)于這些(xie)成分的(de)含量不(bú)同，煤焦(jiao)瀝青的(de)性質也(yě)因而不(bu)同。溫度(du)的變化(hua)對煤焦(jiao)瀝青的(de)影響很(hen)大，冬季(jì)容易脆(cuì)裂，夏季(jì)容易軟(ruan)化。加熱(rè)時有特(tè)殊氣味(wei)；加熱到(dào)260℃在5小時(shí)以後，其(qí)所含的(de)蒽、菲、芘(pí)等成分(fen)就會揮(huī)發出來(lai)。Coal tar is a by-product of coking, namely tar distillation residue in distillation kettle black material.It has respectively with refined tar is only physical properties, there is no clear boundaries, is the way of dividing rules softening point in commonly 26.7 ℃ (cube method) for tar, under 26.7 ℃ above for asphalt.Coal tar mainly contains difficult volatilization of anthracene, phenanthrene, pyrene, etc.These substances have toxic, because the content of these compounds is different, the properties of coal tar are so different.The change of temperature has much effect on the coal tar, winter easy embrittlement, summer is easy to soften.Heating from time to tome special smell;Heated to 260 ℃ after 5 hours, its composition such as anthracene, phenanthrene, pyrene will evaporate. 石油瀝(li)青asphalt 石油(you)瀝青是(shì)原油蒸(zhēng)餾後的(de)殘渣。根(gen)據提煉(liàn)程度的(de)不同，在(zai)常溫下(xia)成液體(ti)、半固體(tǐ)或固體(ti)。石油瀝(li)青色黑(hei)而有光(guang)澤，具有(you)較高的(de)感溫性(xìng)。由于它(tā)在生産(chan)過程中(zhong)曾經蒸(zhēng)餾至400℃以(yǐ)上，因而(er)所含揮(huī)發成分(fen)甚少，但(dàn)仍可能(neng)有高分(fen)子的碳(tàn)氫化合(hé)物未經(jing)揮發出(chu)來，這些(xiē)物質或(huò)多或少(shǎo)對人體(ti)健康是(shi)有害的(de)。Petroleum asphalt is after crude distillation residue.Depending on the degree of refining, into a liquid, semi-solid or solid at room temperature.Petroleum pitch dark and luster, has higher heat resistance.Because it had distillation in the production process to more than 400 ℃, thus contained little volatile component, but may still have high polymer without volatile hydrocarbons, which more or less is harmful to human health. 天然瀝(lì)青Natural asphalt 天然(rán)瀝青儲(chǔ)藏在地(di)下，有的(de)形成礦(kuang)層或在(zai)地殼表(biao)面堆積(ji)。這種瀝(lì)青大都(dou)經過天(tiān)然蒸發(fa)、氧化，一(yi)般已不(bú)含有任(ren)何毒素(su)。Natural asphalt storage in underground, some forming seam or piled up in the earth's crust surface.The asphalt mostly through the natural evaporation and oxidation, generally do not contain any poison. 該泵結(jie)構簡單(dan)，适用範(fàn)圍廣，可(kě)以輸送(song)高粘度(du)和低粘(zhān)度的各(gè)種液體(tǐ)，最高輸(shu)送粘度(dù)可達500000cst-40— 不同(tóng)的使用(yong)條件，泵(beng)的結構(gòu)形式可(ke)能不同(tong)，具體應(yīng)用請向(xiàng)廠家或(huo)本公司(si)客戶代(dài)表咨詢(xun)。需要指(zhǐ)出的是(shi)泵的轉(zhuan)速愈高(gāo)，泵的磨(mo)損愈嚴(yán)重，液體(tǐ)中如含(han)有磨料(liào)物質，泵(beng)的材料(liao)應選用(yong)耐磨材(cái)質，在此(ci)種工況(kuàng)下，泵的(de)壓力和(he)轉速都(dou)應降低(di)，高溫條(tiao)件下，則(ze)應增加(jia)泵的間(jian)隙，并采(cai)用耐熱(re)材料 。
