PH botsitso ba hec
Ho tsitsa hec ha HC se susumetsoa ke lintlha tse 'maloa, ho kenyelletsa sebopeho sa lik'hemimu, se kopane le tikoloho efe kapa efe e teng ka sebopeho.
PH botsitso ba hec ho li-whenges tse fapaneng:
1. Acidic ph:
Acidic Phas, HEC ke ea tsitsitseng empa e ka atleha empa e ka feta linako tse eketsehileng tlasa maemo a thata acidic.

Hydroxethyl celdlouse ea (Hec) o fana ka thepa ea bohlokoa le e sebetsang likolong tse fapaneng. Ho utloisisa botsitso ba eona ho bohlokoa hore barekisi ba hlaole liphallelo tse tsitsitseng le tse sebetsang. Ha Hec Hec a supa botsitso bo botle tlasa maemo a ph a sa nke lehlakore lipolotiki le alkaline ho thibela ho soma le ho netefatsa ts'ebetso e nepahetseng. Ka ho khetha sehlopha se loketseng sa hec, likarolo tse matlafatsang tsa ho boloka thepa, matsale a ka rema lifate tse fapaneng tsa ph.
