瓷磚粘結(jié)劑現(xiàn)在已經(jīng)比較普遍了糊渊，南方城市用的更多一些，尤其對于吸水率比較低的瓷磚虽苫，粘結(jié)的效果會更好些。那么你知道影響濟南瓷磚粘結(jié)劑粘度的原因有哪些嗎碴秽？

Ceramic tile adhesives are now more common, and are more commonly used in southern cities, especially for tiles with low water absorption, the bonding effect will be better. Do you know the reasons that affect the viscosity of Jinan ceramic tile adhesive?

1.極性

1. Polarity

一般說來膠粘劑和被粘體分子的極性影響著粘接強度沾陡，但并不意味著這些分子極性的增加就一定會提高粘接強度。從極性的角度出發(fā)為了提高粘接強度，與其改變膠粘劑和被粘體全部分子的極性蔫沐，還不如改變界面區(qū)表面的極性彼使。例如聚乙烯、聚丙烯激点、聚四氟乙烯經(jīng)等離子表面處理后接馏，表面上產(chǎn)生了許多極性基團，如羥基开辫、羰基或羧基等扇蚯，從而顯著地提高了可粘接性。

Generally speaking, the polarity of adhesive and adhesive molecules affects the bonding strength, but it does not necessarily mean that an increase in the polarity of these molecules will improve the bonding strength. From the perspective of polarity, in order to improve the bonding strength, it is better to change the polarity of the interface surface than to change the polarity of all molecules of the adhesive and the adherend. For example, after plasma surface treatment of polyethylene, polypropylene, and polytetrafluoroethylene, many polar groups such as hydroxyl, carbonyl, or carboxyl groups are generated on the surface, significantly improving their adhesiveness.

2.分子量

2. Molecular weight

聚合物的分子量(或聚合度)直接影響聚合物分子間的作用力颤榛，而分子間作用力的大小決定物質(zhì)的熔點和沸點的高低柿糖，對于聚合物決定其玻璃化轉(zhuǎn)變溫度Tg和溶點Tm.。所以聚合物無論是作為膠粘劑或者作為被粘體其分子量都影響著粘接強度黄锤。

The molecular weight (or degree of polymerization) of a polymer directly affects the intermolecular forces of the polymer, and the magnitude of the intermolecular forces determines the melting and boiling points of the substance. For polymers, it determines their glass transition temperature Tg and melting point Tm. So whether polymers are used as adhesives or as adherents, their molecular weight affects the bonding strength.

一般說來搪缨，分子量和粘接強度的關(guān)系于無支鏈線型聚合物的情況，包括兩種類型鸵熟。種類型在分子量全范圍內(nèi)均發(fā)生膠粘劑的內(nèi)聚破壞副编，這時，粘接強度隨分子量的增加而增加流强，但當分子量達到某一數(shù)值后則保持不變痹届。

Generally speaking, the relationship between molecular weight and adhesive strength is limited to the case of unbranched linear polymers, including two types. The first type undergoes cohesive failure of the adhesive throughout the entire range of molecular weight. At this point, the adhesive strength increases with the increase of molecular weight, but remains unchanged when the molecular weight reaches a certain value.

第二種類型由于分子量不同破壞部分亦不同。這時打月，在小分子量范圍內(nèi)發(fā)生內(nèi)聚破壞队腐，隨著分子量的增大粘接強度增大；當分子量達到某一數(shù)值后膠粘劑的內(nèi)聚力同粘附力相等奏篙，則發(fā)生混合破壞柴淘；當分子量再進一步增大時，則內(nèi)聚力超過粘附力秘通，浸潤性不好为严，則發(fā)生界面破壞。結(jié)果使膠粘劑為某一分子量時的粘接強度為值振沾。

The second type also has different destructive parts due to different molecular weights. At this point, cohesive failure occurs within a small molecular weight range, and the bonding strength increases with the increase of molecular weight; When the molecular weight reaches a certain value and the cohesive force of the adhesive is equal to the adhesive force, mixing failure occurs; When the molecular weight further increases, the cohesion exceeds the adhesion force, and the wettability is poor, leading to interface failure. The result is that the adhesive strength reaches its maximum value at a certain molecular weight.

3.側(cè)鏈

3. Side chain

長鏈分子上的側(cè)基是決定聚合物性質(zhì)的重要因素垛搏，從分子間作用力考慮，聚合物支鏈的影響是莽恩，當支鏈小時肩卡，增加支鏈長度，降低分子間作用力妨试。當支鏈達到一定長度后嗦忍，開始結(jié)晶殊童，增加支鏈長度，提高分子間作用力捉痰，這應(yīng)當是降低或提高粘接強度的原因阐拭。

The side groups on long chain molecules are an important factor determining the properties of polymers. From the perspective of intermolecular forces, the effect of polymer branching is to increase the length of the branching chain and reduce the intermolecular forces when the branching chain is small. When the branch chain reaches a certain length, it begins to crystallize, increasing the length of the branch chain and increasing the intermolecular force, which should be the reason for reducing or improving the bonding strength.
