3-(4-chlorophenyl)-4-phenyl-4,5-dihydro-1H-pyrazole 2-(chloromethyl)-3-methylpyridinehydrochloride 1-(2-bromo-4-methylphenyl)ethanone 3-chloroisoquinoline-4-carbonitrile 5,8-dichloropyrido[3,2-d]pyridazine 2-bromomalononitrile 2-(4-(bromomethyl)phenyl)benzo[d]thiazole 1-(bromomethyl)-3-methoxy-2-nitrobenzene 6-bromo-1H-[1,2,3]triazolo[4,5-b]pyridine 4-iodo-2-((trimethylsilyloxy)methyl)thiazole 6-iodoimidazo[1,2-a]pyridine-3-carbonitrile 2-(4-chlorophenyl)-2-morpholinoacetonitrile 4-chloro-7H-pyrrolo[2,3-d]pyrimidine 4-chloroisothiazole 5-bromo-6-chloro-1H-indole 7-chloro-3H-imidazo[4,5-b]pyridine ethyl3-(4-formylphenyl)propanoate 2,3-dibromobenzaldehyde 1-(5H-chromeno[2,3-b]pyridin-7-yl)ethanone 5H-chromeno[2,3-b]pyridin-5-one 3-chloroisoquinoline-4-carbaldehyde (E)-2-(3-oxoprop-1-enyl)benzaldehyde methyl4-formyl-3-nitrobenzoate 5,6-dimethoxy-2,2-dimethyl-2,3-dihydro-1H-inden-1-one 1-methylbicyclo[4.1.0]heptan-3-one 3-nitro-4-(trifluoromethoxy)benzaldehyde 2-hydroxyquinoline-6-carbaldehyde 2-nitro-3-(trifluoromethyl)benzaldehyde 1-(2-fluoro-4-methoxyphenyl)propan-2-one tert-butyl3-fluoro-4-oxopiperidine-1-carboxylate tert-butyl3-oxopropylcarbamate 2,2-dimethylcyclohexanone 9H-carbazole-3-carbaldehyde N,N-dimethyl-2-oxoacetamide 2-methylpent-4-yn-2-ol 3-tert-butyl-4-hydroxybenzonitrile 4-bromo-2-tert-butylphenol 1,3-dibutoxypropan-2-ol methyl4-hydroxyquinoline-6-carboxylate methyl3-cyano-4-hydroxybenzoate 4-chloro-6-methoxyquinolin-7-ol 3,4-dihydro-2H-benzo[b][1,4]oxazin-7-ol 2-(2-aminothiazol-5-yl)ethanolhydrochloride (R)-ethyl2-chloropropanoate (S)-4-amino-5-(4,4-dimethylcyclohexylamino)-5-oxopentanoicacid (1s,4s)-4-hydroxycyclohexanecarboxylicacid (S)-2-(tetrahydrofuran-3-yloxy)aceticacid (1S,4R)-1-methyl-4-(prop-1-en-2-yl)cyclohex-2-enol (R)-4-(hydroxymethyl)oxazolidin-2-one (S)-4-(hydroxymethyl)oxazolidin-2-one 化工資訊 6月26日，茂名石化化工分部聚丙烯車間開始在2#聚丙烯裝置上試產(chǎn)三元共聚新產(chǎn)品PPD-MT60。工藝主任湛貞、生產(chǎn)主任羅永劍和工程師程劉峰全程跟進(jìn)牌號(hào)切換過程，及時(shí)監(jiān)控指導(dǎo)，實(shí)現(xiàn)了環(huán)管反應(yīng)器從丙丁共聚向三元共聚的平穩(wěn)切換。
“外操外操，立刻到切粒水罐處補(bǔ)水！”到了12時(shí)，主操柯海霞的緊急呼叫聲突然響徹中控室。柯海霞發(fā)現(xiàn)，擠壓機(jī)切粒水罐D(zhuǎn)30806的水位LI8371處于下降趨勢(shì)。此時(shí)，巡檢外操楊鐵軍也用對(duì)講機(jī)反饋現(xiàn)場(chǎng)情況，一樓斗車處出現(xiàn)了粘連料。
經(jīng)驗(yàn)十足的柯海霞立即做出判斷：肯定是預(yù)脫水器處的大塊料閥堵了，導(dǎo)致切粒水無法正常返回切粒水罐！
副班長(zhǎng)黃可健迅速到現(xiàn)場(chǎng)檢查確認(rèn)，并讓外操楊鐵軍到現(xiàn)場(chǎng)打開切粒水補(bǔ)水閥，保證切粒水罐的料位。黃可健現(xiàn)場(chǎng)發(fā)現(xiàn)，預(yù)脫水器大塊料閥處有較多粘連料，并且大塊料閥根本無法正常閉合，切粒水罐水位正持續(xù)下降。如果不及時(shí)將粘連料清理干凈，擠壓機(jī)就會(huì)因切粒水罐水位低導(dǎo)致聯(lián)鎖啟動(dòng)，從而發(fā)生非計(jì)劃停車事故。
冒著65攝氏度的切粒水高溫，黃可健將粘連料一點(diǎn)一點(diǎn)清出來，同時(shí)也不停地調(diào)整大塊料閥閉合開度，確保切粒水水位不再下降。同一時(shí)間，柯海霞及時(shí)調(diào)整相關(guān)參數(shù)，減少粘連料的產(chǎn)生。
經(jīng)過一場(chǎng)驚心動(dòng)魄的時(shí)間追逐賽，12：20分切粒恢復(fù)正常，隨后大塊料閥關(guān)閉，切粒水箱液位開始回升，成功避免了擠壓機(jī)的非計(jì)劃停車。13:45分PPD-MT60各項(xiàng)數(shù)據(jù)達(dá)標(biāo)，標(biāo)志著新產(chǎn)品試產(chǎn)成功。
據(jù)悉PPD-MT60主要用于制造奶茶杯，制品成型性好，透明度高，此次三元共聚的試生產(chǎn)是應(yīng)用新技術(shù)改善產(chǎn)品綜合性能的成功嘗試，有利于增強(qiáng)茂名石化產(chǎn)品的在樹脂市場(chǎng)的競(jìng)爭(zhēng)性。
