流變一致性頻率決定了產(chǎn)品的可取為特定的應(yīng)用。例如，樹脂的表面涂料，涂料制造中的粘合劑。因而實(shí)驗(yàn)室精確的測(cè)定凝膠時(shí)間是生產(chǎn)配方和工藝條件所必要。

Rheological consistency frequency determines the desirability of a product for a particular application. For example, in resins for surface coatings, in paint manufacture, in adhesives. As a result the accurate laboratory determination of gelation time is necessary for the adjustment of manufacturing formulations or control of processing conditions.

利用Techne膠凝計(jì)時(shí)器的機(jī)械壓縮試驗(yàn)優(yōu)于其它方法的，例如，凝膠溶脹試驗(yàn)，攪拌試驗(yàn)，SP1凝膠時(shí)間，因它可重復(fù)的凝膠化時(shí)間與物理化學(xué)形成膠體液時(shí)間一致。該儀器對(duì)彈性而非粘性流體的變化十分敏感，因而提供了更一致和可重復(fù)的結(jié)果。

The mechanical compression test utilized by the Techne Gelation Timer is preferred over other methods, for example, gel swelling test, agitation test, SP1 gel time, because it provides repeatable gelation times consistent with the physical and chemical change in the gelating fluid. The instrument is sensitive to elastic rather than viscous changes in the fluid and as a result provides more consistent and repeatable results

GT-5/6膠凝計(jì)時(shí)器

GT-5/6 Gelation Timers

型號(hào)GT-5/6結(jié)合一個(gè)可移動(dòng)的不銹鋼柱塞被測(cè)液體垂直往復(fù)運(yùn)動(dòng)的機(jī)械裝置。凝膠發(fā)生時(shí)產(chǎn)生的彈性材料支持柱塞的重量導(dǎo)致儀器內(nèi)部的一個(gè)開關(guān)關(guān)閉,時(shí)鐘停止,指示燈開啟。型號(hào)GT-5讀取到最近的一刻。型號(hào)GT-6，精確到0.1分。柱塞的重量保持準(zhǔn)確，有效重量作為儀器往復(fù)移動(dòng)機(jī)制的一部分，以確保相同儀器或不同儀器之間的結(jié)果一致。應(yīng)用于柱塞的往復(fù)運(yùn)動(dòng)的小振動(dòng)來克服摩擦。

Models GT-5/6 incorporate a removable stainless steel plunger which is reciprocated vertically by mechanical means in the liquid under test. When gelation occurs the resulting elasticity of the material supports the weight of the plunger causing a switch inside the instrument to close,the clock to stop and an indicating light to come on. Model GT-5 reads to the nearest minute. Model GT-6 to the nearest 0.1 minute. The weights of the plungers are accurately maintained and the effective weight as part of the reciprocating mechanism in the instrument to ensure consistent and repeatable results with the same instrument and between different instruments. A small vibration is applied to the reciprocating motor of the plunger to overcome friction
