Please demystify cellulose grades and quality
请揭开纤维素的成绩和质量……为什么要使用一个纤维素品牌而不是另一个纤维素品牌？
I need the best for dense packing, new construction dry material install and I want it clean of sulphates.
否则，为什么我要购买一个品牌而不是另一个品牌。我在产品描述中看到了以下内容：
硼酸的浓度
纯与人造硼酸
“纤维化”
干净的原材料来源（纸张与纸板）
基于纤维化和纤维素来源的绝缘值
颜色和纹理
dust content
particulate size
零售价有很大差异……这是质量的代表吗？
提前感谢您的回复。

橡树果园,
Good questions, and not easy to answer briefly. I think that you should be satisfied with the products of any manufacturer. However, the larger manufacturers are more likely to provide good technical help. I'm most familiar with the products and technical service at National Fiber and U.S. Green Fiber, which are both excellent companies.
谢谢，马丁，这就是我发布的原因。您会注意到两个具有非常不同成分的品牌：绿色纤维（在Lowes和HD出售）在硫酸盐上很重，这是散装材料的很大一部分。另一方面，国家纤维不含硫酸盐，并通过专注于纯硼酸的使用来销售点。
If for example, you look at the claims of installed R-values, there are differences between companies, contents, etc. Perhaps fire resistance ratings and insect and mould protection ratings are also different.
是否存在诸如灰尘吸入之类的安全问题；灰尘的热情；安装过程中爆炸的机会；ETC。？我们怎么没有听到与纤维素安装相关的灰尘爆炸？

由于化学和成分，安装人员的健康和房主的健康状况如何？

我还没有看到任何方便安装的东西；材料的流量和可塑性；一旦加压设置并持有产品的力量；最佳管和孔尺寸，距压力障碍的距离等，以获得所需的密度；实现最佳的背压；等等
Green Fiber produces a number of cellulose formulas. If you are interested in an all borate formula, then you can use their 765LD for both dense pack and loose fill.

National Fiber has a quality product too---and their technical support is excellent.
Pyrophoricity? R-value, fire resistance, and insect resistance differences? I think you are getting lost in the details, looking for issues that don't exist.
The borate compounds used to treat cellulose (for fire and insect resistance) have a very low toxicity level---below that of table salt. That said, the manufacturers recommend that you wear a mask when handling the product.
您会做得很好，选择一家制造商，遵循他们的安装指南，并在您有其他疑问的情况下与他们的技术部门交谈。
纤维素安装过程中的大部分灰尘是阻燃的，而不是纤维素纤维 - 难以烧毁一团燃烧的云，是吗？
钻石是非挥发性的 - 它们不会悬挂在空中，不能穿过墙壁等，并且（正如丹尼尔指出的）人类的毒性非常低。唯一真正的曝光危险是在安装期间 - 一旦将其扣在墙上，它就会留在那里。
硼酸盐对需要这些原生动物来加工受损的木材的肠道虫（木匠/黄蜂/白蚁等）的肠道菌群有毒，并将通过剥夺宿主昆虫的营养而杀死宿主昆虫。即使是那些不吃木材营养的昆虫（例如木匠蚂蚁），这也是这样，因为积累的木纤维素会干扰其余的消化。由于那些昆虫会吞噬弱者和死亡，即使是不吃硼酸盐的人也被杀死，而且由于饥饿需要时间，因此甚至可以消除偏远的巢穴。这使纤维素的高脑化版本成为常见木材无聊昆虫的区域中更可取的绝缘材料。（尽管对建筑物组件的适当水分管理也是关键的一阶预防步骤。
I have no ideas what "artificial boric acid" is. If it's chemically identical H3BO3, who cares if it was synthesized from other feedstocks vs. dug out of a hole in the ground somewhere?
在我的本地市场，我没有看到“ ...零售价的广泛变化……”。任何配方的任何供应商似乎总是在20％的窗口F.O.B.分销商的院子，我什至从一个来源的全陈旧商品中以硫酸盐的价格来自另一个来源的价格 - 我猜想这仅取决于现货市场的当地需求。全纤维材料的典型保费在5-10％的范围内，但这是项目总成本变化的“噪音”。显然是ymmv。
National Fiber is just one vendor that I've used for dense packing, but since the distributor is quite close to me, it's mostly an ease of access thing. I've been satisfied with how their CelPak dry-blow goods install, but can't say that it's dramatically easier or harder than other vendor's goods. (I'm not in that biz, but I've done my own dense-packing ever since acquiring an insulation blower a handful of years back.)
