light and heavy 钙

01  basic concept, in ratio surface 积方面, 1000目 left right heavy and light ratio surface 积均约 is 4.5, in mono quality powder in, it surface performance versus 当. however, this in property can upper large versus 径庭, water difficult 容. significantly difference in poly property. light 钙 团 poly property relatively strong/high, heavy versus for relatively low. this 引发 一 issues: can use what indicators amount powder 体 团 poly phenomenon? more deep 层次 思考, poly is and powder surface structure has 关? this issues value in-depth discussion, is poly phenomenon effect/influence to product dispersion and property can.

02  ratio surface and property can comparison, light is through chemical pure method made as formed. 首先, will 石灰石 add hot high temperature, is 生石灰, rear hydrolysis, formed hydrogen oxidation 钙. 接, utilizing oxidation carbon reaction, in water versus in made fine small carbon acid powder 体, usually small 于12 micron. and different is, heavy is through material abrasion will understanding 石, large 理石, 石灰石 and other processing formed powder 体. this in appearance upper has significantly difference: light 钙呈纺锤体, heavy is 不规则形状. in micron grade pellets in, this type of appearance 差异似乎并未 for property can generate obvious effect/influence.

03 吸油 value 奥秘, value is key/critical indicators. light 钙 吸油 value high heavy 钙, rear is front 者 1/3 to 1/4. tube/pipe ratio surface versus 近, this large let 人不禁思考, is in 悄悄“偷油”? this and coating material or structure 胶密切 related. 例如, 107胶 price 不菲, 但吸油 value low powder 体往往 flow property good, however has outer in. has heavy 钙 吸油 value large understanding 石, flow property color large powder 体, this is is 何?

04 塑化方面, light by filling 至PVC in 时, speed degree fast, electrical high, most formed type gloss degree relatively high. heavy 钙 塑化 speed degree relatively slow, electrical low, type gloss degree 自然也不如 light 钙. ratio surface versus 似 两者, is in application in 却呈现出如此 large 差异? for 此, need more add in-depth research.

through for above issues 思考, summary lower:

01: structure property can: material property is 基础, chemical analysis can 够帮助我们 more 清楚 理 understanding.

02: powder structure and property can: this between 关系, will can 揭示一 product in value.

03: surface effect/influence: light and heavy surface structure significantly, 但当达 to fine degree 时, its property can can can 趋同. property factors is 另一项 need 考虑 维 degree
