class="title">詳細(xì)說明</p><div id="xf3zg8q" class="box"><p><p> 碳酸鈣（CaCO3）是一種重要的、用途較廣的無機(jī)鹽，根據(jù)加工方式的不同通常分為重質(zhì)碳酸鈣和輕質(zhì)碳酸鈣。碳酸鈣無論是重質(zhì)碳酸鈣還是輕質(zhì)碳酸鈣，是塑料、橡膠、造紙等工業(yè)中使用數(shù)量大、應(yīng)用面廣的粉體填料。 </p> <p> <br /> </p> <p> 重質(zhì)碳酸鈣：又稱研磨碳酸鈣，簡稱重鈣，是以天然方解石、石灰石、白云石、白堊、貝殼等為原料通過物理方法加工制得。輕質(zhì)碳酸鈣：又稱沉淀碳酸鈣，簡稱輕鈣，是用化學(xué)方法加工制得。碳酸鈣可以降低塑料制品的原材料成本，海曙區(qū)普通輕質(zhì)碳酸鈣好口碑，還具有改善塑料材料某些性能的作用。研究成果表明，不同種類的碳酸鈣在使用得當(dāng)時，可明顯地提高基體塑料的性能，海曙區(qū)普通輕質(zhì)碳酸鈣好口碑。

在半結(jié)晶聚合物基體里加入精細(xì)的經(jīng)過表面處理的CaCO3改善了吹塑薄膜的性能，如： </p> <p> ● 增加剛度 </p> <p> ● 提高落錘耐沖擊性能 </p> <p> ● 防粘連效果 </p> <p> ● 提高抗撕裂蔓延性（埃爾曼多夫） </p> <p> ● 改善阻隔性能 </p> <p> ● 略微增加表面張力 </p> <p> ● 未拉伸：提高薄膜密度 </p> <p> ● 拉伸：降低密度，必要時還有滲透作用 </p> <p> 上述聚合物性能的變化幅度在很大程度上取決于薄膜成分、薄膜厚度、礦物含量以及CaCO3類型。 </p> <p> <br /> </p> <p> CaCO3成功應(yīng)用于吹塑薄膜的實例包括購物袋、背心袋、垃圾袋、紙狀薄膜，農(nóng)用薄膜、重型包裝袋以及背板薄膜。 </p> <p> （2）降低配方成本 </p> <p> CaCO3的加入提高了薄膜密度，因此有必要降低薄膜厚度以保持恒定的薄膜重量，即所謂的向下計量。值得注意的是，這種增長與礦物含量不存在線性關(guān)系。例如：CaCO3含量為30%，薄膜厚度*需減少20%即可保持薄膜的重量恒定。 </p> <p> （3）提高可持續(xù)性 </p> <p> 整個工藝鏈還額外節(jié)省了能源。通過混合CaCO3粉末，超融合技術(shù)還提供了更高的可持續(xù)性。該工藝在擠出過程中節(jié)省了熱能，因為這些礦物具有比聚合物明顯更低的比熱。從這一結(jié)果來看，該技術(shù)能夠明顯降低產(chǎn)品的碳排放量及其對環(huán)境的影響。 </p> <p> <p> （4）直接加料的優(yōu)勢 </p> <p> CaCO3的直接加料能夠大量節(jié)省原料成本。 </p> 寧波納米碳酸鈣重質(zhì)碳酸鈣與輕質(zhì)碳酸鈣，當(dāng)填充碳酸鈣超過30份以上時，輕質(zhì)碳酸鈣對邵A硬度的貢獻(xiàn)比重質(zhì)碳酸鈣稍大。</p> <span style="display:none;"></span><div style="width:100%;text-align:

納米碳酸鈣在造紙中的應(yīng)用 </p> <p> 應(yīng)用范圍：卷煙紙、記錄紙、簿頁印刷紙、高白度銅版紙以及**衛(wèi)生巾、紙尿布等。 </p> <p> 應(yīng)用特性：造紙中加入納米碳酸鈣可以提高紙張的松密度、表觀細(xì)膩性、吸水性；提高特種紙的強(qiáng)度、高速印刷性；調(diào)節(jié)卷煙紙的燃燒速度。 </p> <p> 造紙業(yè)是納米碳酸鈣相當(dāng)有開發(fā)潛力的市場。納米活性碳酸鈣作為造紙?zhí)盍暇哂幸韵聝?yōu)點：高蔽光性、高亮度、可提高紙制品的白度和蔽光性；高膨脹性，能使造紙廠使用更多的填料而大幅度降低原料成本；粒度細(xì)、均勻，制品更加均勻、平整；吸油值高、能提高彩色紙的預(yù)料牢固性。 </p> <p> 可用于涂布加工紙的原料，特別是用于高級銅板紙。由于它分散性能好，粘度低，能有效的提高紙的白度和不透明度，改進(jìn)紙的平滑度、柔軟度，改善油墨的吸收性能，提高保留率。 </p> <p> 碳酸鈣在造紙中主要作紙張的填料，為了保證紙張的一定強(qiáng)度、白度，同時降低成本，在紙張中添加大量碳酸鈣。造紙行業(yè)中大量使用碳酸鈣是基于國際上造紙工業(yè)從酸性造紙工藝轉(zhuǎn)向堿性或中性造成紙工藝，這樣就可以大量使用價廉的碳酸鈣代替以往的滑石和瓷土。 </p><p> 碳酸鈣呈白色固體狀，無味、無臭。有無定型和結(jié)晶型兩種形態(tài)。結(jié)晶型中又可分為斜方晶系和六方晶系，呈柱狀或菱形。相對密度2.71。825～896.6℃分解，在約825℃時分解為氧化鈣和二氧化碳。熔點1339℃，10.7MPa下熔點為1289℃。難溶于水和醇。與稀酸反應(yīng)，同時放出二氧化碳，呈放熱反應(yīng)。也溶于氯化銨溶液。幾乎不溶于水。 </p> <p> 遇稀醋酸、稀鹽酸、稀硝酸發(fā)生暴沸，并溶解。在101.325千帕下加熱到900℃時分解為氧化鈣和二氧化碳。在一大氣壓下將碳酸鈣加熱到900℃會分解成生石灰和二氧化碳（工業(yè)制取CO?）。由于碳酸鈣白度在90以上,還可以取代昂貴的白色顏料。</p><div style="width:100%;text-align: center;"><img style="max-width:

用途：橡膠的填充料，可使橡膠色澤光艷、伸長率大、抗張強(qiáng)度高、耐磨性能良好。還用作制人造革、電線、聚氯乙烯、涂料、油墨和造紙等工業(yè)的填料。可使成品具有一定的抗張強(qiáng)度及光滑的外觀。生產(chǎn)微孔橡膠時，可使其發(fā)泡均勻。 </p> <p> 制法及工藝流程 </p> <p> 碳化法：石灰石在高溫下煅燒之后，先用水消化，再經(jīng)篩濾、碳化、表面處理、干燥粉碎后，即得膠體碳酸鈣成品。海曙區(qū)普通輕質(zhì)碳酸鈣好口碑</p><p
