Putty yana jin nauyi

A lokacin gina putty, wasu mutane za su fuskanci yanayin da hannun ke jin nauyi. Menene takamaiman dalili? Ta yaya za a inganta shi?

Dalilan gama gari da yasa putty ke jin nauyi sune:

1. Amfani mara kyau na samfurin danko na ether cellulose:

A wannan yanayin, danko na ether cellulose gabaɗaya ya yi yawa sosai, kuma abin da aka yi sa zai ji nauyi yayin aikin gogewa;

Wani dalili kuma shi ne cewa a lokacin ginawa a lokacin rani, yin amfani da hydroxypropyl methylcellulose ether tare da mummunan yanayin zafi na iya sa putty ya rasa danko, wanda zai shafi ginin ginin.

2. Rabo mara kyau ko ingancin foda:

Gabaɗaya, akwai kayan gelling na inorganic da yawa, ko kuma ingancin filler ɗin da aka zaɓa ya yi kyau sosai, wanda ke da saurin mannewa wuka;

Hakanan yana yiwuwa don rage farashin, babu ko žasa da ƙari don inganta jin daɗin hannun da aka ƙara, kamar sitaci ethers da thixotropic lubricants.
