石蜡基

When the powder loading was fixed as 58%,the molded compact of a gearwheel whose addendum circle diameter is 700 μm was obtained with well shape retention.

3μm的羰基铁粉和石蜡基热塑性粘结剂体系，当粉末的装载量为58%时，获得了形状良好的齿顶圆直径为700μm的微型齿轮注射生坯。

Bried introdution: The product is from oil lube distillate cut and leavings without asphaltum.

产品简介：本产品以精制的大庆石蜡基油为基础油，添加极压，抗磨剂，防锈剂、防氧剂、抗泡剂等多种优良添加剂调试而成。

with the hydroisomerization dewaxing process of shell company, apiⅱgroup and apiⅲgroup lube base oils were produced by taking vgo no.4 and dao from xinjiang karamay paraffin crude oil as raw materials after a series of lab tests and commercial trial production. the developed oils can meet the quality requirements of hviwh300 and vhvih90bs respectively. but all the haze points of the two products are about 16 ℃, and the floccus will appear in these oils with the time going by. the problem of haze point in high viscosity lube oil will still need to study continually.

采用壳牌公司以异构脱蜡催化剂为核心的全加氢工艺，对新疆克拉玛依石蜡基原油减四馏分油、轻脱油进行了实验室工艺研究，并经工业试生产，可以生产出apiⅱ、ⅲ类润滑油基础油，其主要产品性质可以分别满足中国石油hviwh300、vhvih90bs的质量要求，但这两种大粘度产品浊点达到16 ℃左右，室温下长期存储会出现絮状物，需要进一步研究解决。

Make incomplete heavy oil or olefin base crude oil comes to those who raise light oil close through deepness treatment method rate, finished product can serve as after classics of the benzine of generation, derv is purificatory, shan of the cent that weigh heat up in a steamer can serve as catalytic cracking or thermal cracking raw material, coke can serve as the raw material of production electrode, have ask rest method and continuous method etc.

使残重油或石蜡基原油通过深度加工方法来提高轻油的收率，产生的汽油、柴油经精制后可作为成品，重馏分汕可作为催化裂化或热裂化原料，焦炭可作为制造电极的原料，有问歇方法和连续方法等。

The construction of the heavy rawmaterial MEK toluol unit depended on resources superiority of paraffin base oil inHenan oil field , the microcrystalline wax products share and the competitive powerin the market might enhance.

装置的建成，充分依托了河南油田石蜡基原油的资源优势，可以提高微晶蜡产品的市场占有率和市场竞争力。

In order to reduce the cost for formulating lubricating oil, a small fraction of paraffinic base oil can be added into naphthenic base oil as far as the property of lubricating oil can meet the specification.

因此，为了减小润滑油的生产成本，可以在满足润滑油性能的基础上在所用的环烷基基础油中加入少量的石蜡基油。

The influence of paraffinic base oil on the performance of naphthenic base oil was investigated by studying the low-temperature viscosity of tested oils.

根据混合油样的低温运动粘度结果研究了石蜡基油对环烷基油性能的影响。

The viscosity of lube oils increased with an increasing content of high-viscosity paraffinic base oil in the oil mixture.

混合油样的粘度随着高粘度石蜡基油含量的增加逐渐增加。

Three kinds of FCC slurries from various crude oils were involved including naphthenic, intermediate and paraffinic base.

采用一种新型溶剂对环烷基，中间基，石蜡基FCC油浆进行萃取，分别得到饱和烃和芳烃。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
