1. 熔化玻璃，最省工，省錢的方法
一、用具
1、坩堝（模具）：它是用耐火材料製作而成，三使用前需檢查坩堝漏孔是否有砂眼、破裂、多眼、穿孔，漏板是否平整，檢查後進行預熱並置坩堝架上調試。坩堝在各耐火材料廠有生產供應，生產玻璃纖維的廠家也用此物。浙江省金華市較店鎮北山路金華市面磚廠長期供應各規格坩堝，每隻150孔1.70元，120孔1.60元，孔徑1.7，1.8，1.9，2.0，2.1，2.2，毫米的，我們使用2.2毫米大孔徑的坩堝為好。聯系人：方一，郵政編碼：321021，金華市廣場坐3路公共汽車直達。另：湖南省冷水灘市保險公司後面米家山路玻纖廠有售，聯系人：姜師傅，郵政編碼：425100；山東省淄博市淄川玻璃窯材料廠有售，聯系人：劉恩禮，郵碼：25154；山西省侯馬市晉都立交交橋西配件廠背後侯馬市南堡金湯坩堝廠有售，聯系人：吳明秀，郵碼：158321；江蘇省海安縣南屏坩堝廠有售，郵碼：21661；安徽省鳳陽縣坩堝廠有售，郵碼：233100。以上廠家地址請學員自己就近選擇，應先去信聯系好，再去人或託人購買，不能托動和郵寄。
2、噴打：是點引坩蝸（融化玻璃）的引火用具，只有在噴打高溫下，使玻璃熔化為液體，才能使玻璃自然充電並溶化，點燃噴燈時要噴燈完全預熱至工作狀態（噴燈呈藍色火焰）方可使用。（噴燈有汽油、煤油、柴油之分，以汽油噴燈為佳。在各縣市五交化公司門市部有售50元一隻）。另：也可用噴燈點火，而用化學葯物點火，化學葯物為氫氧化鈉，精細食鹽（氫氧化鈉是化學試劑葯物，各縣市化學試劑商店、醫葯公司試化櫃台，各縣市醫院化驗室或生化檢驗科均有售，每瓶500元，8元，可使用一年，精細食鹽就是家庭食用鹽，研成細末即可，一斤也可用上一年，成本極低）。
3、電極片、爐絲：電極片也稱堝片或電極板，是溝通電源重要部件，用鋼板和鋼筋焊接而成。爐絲也稱引火線，是用14號小鐵絲使用。
4、工作台：主要用來支撐坩堝架和添加玻璃方便的檯子，此台要300塊磚，一包水泥砌成，坩堝架用角鐵焊接而成，安裝時要求四周平衡至水平。
5、拉絲鉗：用6-8號鋼筋製作（手握部位要進行絕緣），鉗口要平衡、整齊，使用時要求輕松自如。另：用50公分長的玻璃棒管也可引接牽拉玻璃絲。
6、電源線路：電源要求具有三相電源（功率2.5千瓦以上），即兩根火線、一根零線，使用電表需10安以上，30-60安培三相總電閘一隻，30安培一閘兩用倒順閘刀一隻，一頭接兩根火線380伏，另一頭接一根零線220伏電源，使380伏及220伏能交替使用。

2. 哪裡有賣食用純鹼碳酸鈉的
1、食品添加劑商店都有
2、超市也有
3、食雜店多數也有
4、標食用鹼的就是了
3. 純鹼是啥化學式,純鹼一般哪裡有賣
1.純鹼即碳酸鈉，是一種無機化合物，其分類屬於鹽，不屬於鹼。
2.純鹼是一種重要的無機化工原料，主要用於平板玻璃、玻璃製品和陶瓷釉的生產，也廣泛用於生活洗滌、酸類中和以及食品加工等，還用於照相術和分析領域。
4. 介紹焦作的英語演講稿
Jiaozuo City, Henan Province is located northwest of the north border of Shanxi Taihang, south of the Yellow River in Zhengzhou, Luoyang sea. 4 jurisdiction over 2 cities and 4 counties and 1 district tech Instry Development Zone, with a total area of 4071 square kilometers, with a total population of 3,455,000, of which the urban population of 807,000, the urban population 1,331,000. In 2004, the Jiaozuo City realized 45.523 billion yuan GDP, per capita GDP reached 13,413 yuan, according to the current exchange rate can be converted into $ 1,633; Last year's local revenue of 2.44 billion yuan, fixed assets investment 18.72 billion yuan, All the instrial added value 23.51 billion yuan, per capita disposable income of urban residents per capita net income of rural residents reached 7,286 yuan, 3,374 yuan, urban and rural residents amounted to 25.39 billion yuan savings deposits. Jiaozuo has a superior geographical advantages. It is located in the intersection of North and South, East and West junction, but also a new Eurasian Continental Bridge in the heart of China, with east and west, north, Nantong hub groove. Jiaozuo has convenient transportation advantages. It is located in the north and south of the Yellow River channel, briefly hub of Shanxi Henan provinces, Henan Northwest has always been an important material distribution center. Coke territory branches (Jiaozuo - Zhicheng), coke too (Jiaozuo - Taiyuan), Jiao Xin (Jiaozuo - Xinxiang), Hou month (month Mountain - Houma) four railway lines, on mountains, to be king two large freight marshalling yard and railway transportation. The city's total length of 4953 km, road density, 121.6 km / hundred square kilometers, much higher than the provincial and the national average. Zheng has been built within the coke, coke Jin two high-speed, mileage of 72.8 kilometers, is under construction coke temperature, the new focus of economic, Ji Luo three high-speed, "fifteen" at the end, Jiaozuo will achieve "every county high-speed," the goal central city to city and county can achieve high-speed connection, will be to build up a half-hour economic circle, the city's expressway network will also work with the Beijing-Zhuhai, too Australia and even the national trunk highway Huo and other connectivity, Jiaozuo in central and western China region will be more obvious location advantages, economic radiation further enhanced. Jiaozuo has unique natural resources. First, very rich in mineral deposits. There 40 kinds of mineral resources with proven reserves of coal, limestone, bauxite, refractory clay, pyrite and other 20 kinds, including recoverable reserves of 600 million tons coal, into a single high-quality anthracite, is the chemical and steel ideal for instrial raw materials; refractory clay shallow, easy to exploit, is the proction of ceramics, high-quality refractory raw materials, has proven reserves of 50.49 million tons; iron ore reserve is 27.26 million tons of instrial reserves of 7.406 million tons, the magnetite Lord, the iron content of 32%; limestone reserves of 100 million tons forecast, the proction of soda ash, acetylene, cement and other procts of high quality raw materials; pyrite reserve is 34.755 million tons, accounting for 41% of the province's reserves. Second, abundant water resources. Jiaozuo is a rare water-rich North China area, many rivers within the basin area of 100 square kilometers of the river there are 23, there cited Qin channel, Kwong Lee two artificial drainage channels, there are heroes, Qingtian River, White wall, along streams and other large reservoirs, water diversion project will also benefit from the construction of the cut through downtown and over, which gave ample Jiaozuo bring surface water; particularly important, Jiaozuo City, is a natural collection of groundwater basins, and the southeastern mountains of northern mountainous area about 1400 square kilometers of the majority, are groundwater recharge areas of Jiaozuo, shallow groundwater in these areas and part of precipitation, in a complex geological structure under the control of collection to the city, karst formation of more abundant water resources, has proven reserves of 3.54 billion cubic meters of groundwater. In addition, the Taihang Mountains in the south of the northern distribution of Jiaozuo of about 500 square kilometers of land and gravel sloping piedmont plains Kong, hard solid geological strata great stamina, and neighbors deposits, water, transportation routes and towns, is highly desirable instrial land also very suitable for the construction of high-rise buildings.

焦作市位於河南省西北部，北依太行與山西省接壤，南臨黃河與鄭州、洛陽相望。現轄2市4縣4區和1個高新技術產業開發區，總面積4071平方公里，總人口345.5萬，其中市區人口80.7萬,城鎮人口133.1萬。
2004年，焦作市實現地區生產總值455.23億元，人均生產總值達到13413元，按現行匯率可摺合為1633美元；全年完成地方財政收入24.4億元，全社會固定資產投資187.2億元，全部工業增加值235.1億元，城鎮居民人均可支配收入和農村居民人均純收入分別達到7286元、3374元，城鄉居民儲蓄存款余額為253.9億元。
焦作有著優越的區位優勢。它地處我國南北交匯點，東西結合部，又是新歐亞大陸橋在中國境內的中心地帶，具有承東啟西、溝南通北的樞紐地位。
焦作有著便利的交通優勢。它地處黃河南北之通道，扼晉豫兩省之要沖，自古就是豫西北地區重要的物資集散地。境內有焦枝（焦作--枝城）、焦太（焦作--太原）、焦新（焦作--新鄉）、月侯（月山--侯馬）四條鐵路線，有月山、待王兩個較大的貨運編組站，鐵路交通便利。全市公路總里程達4953公里，公路密度121.6公里/百平方公里，遠高於全省和全國平均水平。境內已建成焦鄭、焦晉兩條高速，通車里程達72.8公里，正在建設焦溫、新焦濟、濟洛三條高速，「十五」末，焦作將實現「縣縣通高速」的目標，中心城市到各縣市均可實現高速連接，屆時將構築起一個半小時經濟圈，全市的高速公路網也將與京珠、太澳、連霍等國家干線高速公路連通，焦作在我國中西部地區的區位優勢將更加明顯，經濟輻射能力進一步增強。
焦作有著得天獨厚的自然資源。一是礦藏十分豐富。有礦產資源40多種，探明儲量的有煤炭、石灰石、鋁礬土、耐火粘土、硫鐵礦等20多種，其中煤田可開采儲量6億噸，為單一的優質無煙煤，是化工和鋼鐵工業的理想原料；耐火粘土埋藏淺，易開采， 是生產陶瓷、耐火材料的優質原料，已探明儲量5049萬噸；鐵礦保有儲量2726萬噸，工業儲量740.6 萬噸，以磁鐵礦為主，含鐵量32%；石灰石預測儲量100億噸，是生產純鹼、乙炔、水泥等產品的優質原料；硫鐵礦保有儲量3475.5萬噸，佔全省儲量的41%。二是水資源充沛。焦作是華北地區不可多得的富水區，境內河流眾多，流域面積在100平方公里以上的河流有23條，還有引沁渠、廣利渠兩大人工渠，有群英、青天河、白牆、順澗等較大水庫，即將修建的南水北調工程也將從中心城區斜穿而過，這些都給焦作帶來了充裕的地表水資源；特別重要的是，焦作市是一個天然的地下水匯集盆地，北部山區及晉東南山地約1400平方公里的廣大地區，均為焦作地下水的補給區，這些地區的淺層地下水和部分降水，在復雜的地質構造控制下，匯集到我市，形成較為豐富的岩溶水資源，目前已探明地下水儲量35.4億立方米。另外，在焦作北部太行山南麓分布著約500平方公里的山前崗地和礫石傾斜平地，地質堅硬穩固，地層耐力巨大，且近鄰礦點、水源、交通干線和城鎮，是極為理想的工業用地，同時也非常適宜建造高層建築。
