2021/03/05

1. Ba chóir go mbeadh na dathanna a bhaineann le gliú difriúil. Mura bhfuil aon riachtanas speisialta ann maidir le dath an táirge leantach féin, moltar greamachán leá buí a úsáid. Go ginearálta, tá greamachán leá te buí níos bán viscousthan. Láimhseálann an tábla seachtrach é. Le go ndéanfar cóireáil dromchla ar an gcuid a cheangal, níl an ghreamaitheach leá te chomh dian le greamacháin eile, ach ar cheart an deannach agus an ola ar dhromchla na coda atá le ceangal a chur i gceart? Ar an mbealach seo amháin, angreamachán leá teis féidir le cáithníní níos fearr a dhéanamh ar an nascáil.

 

2. Working hours. Hot melt adhesive has the characteristics of fast operation. With the wide application of modern production methods-assembly lines, the working time requirements for greamachán leá tes are getting shorter and shorter, such as book binding, speaker manufacturing, etc., and the working time requirements for greamachán leá tes are getting shorter and shorter, about 5 second.

 

3. Resistance to temperature. Thermal adhesives are sensitive to temperature. Will the temperature change? The greamachán leá te starts to soften and becomes brittle at a certain temperature. Therefore, the temperature change of the environment where the product is located should be considered when selecting the hot melt adhesive.
