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(li)青Coal tar 石油瀝(lì)青asphalt 石油(yóu)瀝青是(shi)原油蒸(zhēng)餾後的(de)殘渣。根(gen)據提煉(liàn)程度的(de)不同，在(zài)常溫下(xià)成液體(tǐ)、半固體(tǐ)或固體(tǐ)。石油瀝(lì)青色黑(hēi)而有光(guang)澤，具有(yǒu)較高的(de)感溫性(xìng)。由于它(tā)在生産(chan)過程中(zhōng)曾經蒸(zhēng)餾至400℃以(yǐ)上，因而(er)所含揮(huī)發成分(fen)甚少，但(dan)仍可能(neng)有高分(fèn)子的碳(tan)氫化合(he)物未經(jīng)揮發出(chū)來，這些(xie)物質或(huo)多或少(shao)對人體(tǐ)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(li)青Natural asphalt 天然(ran)瀝青儲(chǔ)藏在地(di)下，有的(de)形成礦(kuang)層或在(zai)地殼表(biǎo)面堆積(jī)。這種瀝(li)青大都(dōu)經過天(tian)然蒸發(fa)、氧化，一(yi)般已不(bu)含有任(ren)何毒素(sù)。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. 瀝青材(cai)料分為(wei)地瀝青(qing)和焦油(you)瀝青兩(liǎng)大類。地(di)瀝青又(you)分為天(tian)然瀝青(qīng)和石油(you)瀝青，天(tiān)然瀝青(qing)是石油(yóu)滲出地(di)表經長(zhang)期暴露(lù)和蒸發(fā)後的殘(cán)留物；石(shí)油瀝青(qīng)是将精(jing)制加工(gōng)石油所(suǒ)殘餘的(de)渣油，經(jing)适當的(de)工藝處(chù)理後得(dé)到的産(chǎn)品。焦油(yóu)瀝青是(shì)煤、木材(cai)等有機(jī)物幹餾(liú)加工所(suǒ)得的焦(jiao)油經再(zai)加工後(hou)的産品(pǐn)。工程中(zhong)采用的(de)瀝青絕(jue)大多數(shu)是石油(you)瀝青，石(shí)油瀝青(qīng)是複雜(zá)的碳氫(qing)化合物(wù)與其非(fēi)金屬衍(yǎn)生物組(zǔ)成的混(hun)合物。通(tong)常瀝青(qīng)閃點在(zai)240℃~330℃之間，燃(ran)點比閃(shan)點約高(gao)3℃~6℃度，因此(cǐ)施工溫(wen)度應控(kòng)制在閃(shǎn)點以下(xia)。Asphalt material divided into two categories, pitch and bitumen.Asphalt is divided into natural asphalt and petroleum asphalt, natural bitumen is oil seepage surface after long exposure and evaporation residue;Petroleum asphalt is a residual of residual oil will be refined processing, after appropriate processing products.Bitumen is coal, wood and other organic matter carbonization processing tar after reprocessing of products.Engineering used in the asphalt is the vast majority of asphalt, asphalt is a complex mixture of hydrocarbons with nonmetal derivatives.Usually asphalt flash point between 240 ℃ ~ 330 ℃, flash point is higher than flash point about 3 ℃ ~ 6 ℃ degrees, so the construction temperature should be controlled below the flash point.v 瀝青輸(shu)送泵是容(róng)積式内(nei)齧合齒(chǐ)輪泵，主(zhǔ)動齒輪(lún)（外轉子(zi)）帶動被(bei)動齒輪(lun)（内轉子(zǐ)）旋轉時(shi)，不斷産(chan)生封閉(bi)的空間(jian)，在吸油(you)區齒輪(lun)逐漸脫(tuō)離齧合(he)而液體(ti)不斷地(di)充滿齒(chǐ)間并被(bei)帶到出(chu)油區，齒(chǐ)輪在出(chu)油區進(jin)入齧合(he)時液體(tǐ)被排出(chū)。兩個旋(xuán)轉齒輪(lun)的共同(tóng)作用，形(xing)成一個(gè)穩定的(de)體積排(pai)量，沒有(yǒu)脈動。由(you)于泵是(shì)完全對(dui)稱的，泵(bèng)可以反(fǎn)轉，液流(liú)方向也(yě)随之改(gǎi)變。但應(yīng)注意，泵(beng)的轉向(xiàng)可能受(shou)到密封(fēng)或泵内(nei)其它結(jié)構的限(xiàn)制，用戶(hu)有反轉(zhuǎn)要求時(shi)應在訂(ding)貨時做(zuo)出說明(ming)。 500000cst。溫度(dù)範圍自(zi)-40— 不同(tóng)的使用(yòng)條件，泵(beng)的結構(gou)形式可(ke)能不同(tóng)，具體應(yīng)用請向(xiàng)廠家或(huo)本公司(si)客戶代(dai)表咨詢(xun)。需要指(zhi)出的是(shì)泵的轉(zhuǎn)速愈高(gāo)，泵的磨(mo)損愈嚴(yan)重，液體(tǐ)中如含(hán)有磨料(liao)物質，泵(bèng)的材料(liào)應選用(yòng)耐磨材(cai)質，在此(cǐ)種工況(kuang)下，泵的(de)壓力和(he)轉速都(dou)應降低(dī)，高溫條(tiáo)件下，則(zé)應增加(jiā)泵的間(jiān)隙，并采(cǎi)用耐熱(rè)材料 。
