Sidee loo diiwaan gelin karaa heerkulka kaydinta ee hydroxyethyl acrylate?

Xogta cilmi-baarista waxay muujinaysaa in haddii heerkulka haanta kaydinta ee hydroxyethyl acrylate uu ka hooseeyo 15°C muddo dheer inta lagu jiro kaydinta, qaar ka mid ah sifooyinkiisa jireed ayaa laga yaabaa inay saameeyaan. Sidaa darteed, waxaa ka wanaagsan in heerkulka lagu hayo heer dhexdhexaad ah intii suurtagal ah. La socodka maalinlaha ah, heerkulka haanta kaydinta hea hydroxyethyl acrylate waa in la duubaa 2dii saacadoodba mar si loo ogaado xaaladaha heerkulka aan caadiga ahayn si waqtigeeda ah loona qaado tallaabooyin u dhigma si loo hubiyo badbaadada kaydinta.

Marka laga eego dhinaca kaydinta badbaadada leh, marka heerkulka hydroxyethyl acrylate uu Kaydinta HEA hababka taangiga25°C, waa in la hawlgeliyaa habka digniinta hore, qalabka sida nidaamka qaboojintana waa in si habboon loo hubiyaa si looga hortago in heerkulku sii kordho.

Si loo kaydiyo heerkulka hydroxyethyl acrylate muddo dheer, heerkulka taangiga waa in la dejiyaa qiyaastii. 18°C, maadaama xaaladdan heerkulku ay sare u qaadi karto dammaanadda xasilloonida kiimikada iyo cimri dhererka tayada badeecadda.

Qaab-dhismeedka hydroxyethyl acrylate HEA wuxuu go'aamiyaa inuu leeyahay polarity gaar ah. Sababtoo ah farqiga elektaroonigga ah ee atomyada kala duwan ee molecule-ka, qaybinta dallacaaddu waa mid aan sinnayn. Polarity-gani wuxuu u oggolaanayaa inuu si fiican ula jaanqaado qaar ka mid ah dareerayaasha polarity-ga, sida ethanol iyo biyo.
