家用洗衣机主要依靠冼涤液与衣物之同的相对运动来达到洗净、脱水目的。洗涤液中的水的功能主要起膨润作用,它能把衣物上的污秽物泡胀,使之分脱离落;肥皂粉或洗涤剂的功能有二,一是物理作用,加强水的膨润作用,使衣物上的污秽物更易脱落,二是化学作用,衣物上的油污可与碱性洗涤液起皂化反应,形成水溶性化合物,溶解在水中,为了加速衣物污秽脱落,还要利用洗衣机的物理功能,使洗涤液和衣物在相对运动中产生离心作用,把衣物上的污秽物有效地分离开。影响洗净效果的因素是多方面的,首先 Household washing machines mainly rely on Xi washing liquid and clothing with the same relative movement to achieve the purpose of washing, dehydration. The function of the water in the washing liquid mainly plays the role of swelling, which can swell the grime on the clothes so as to separate them off. The functions of the soap powder or the detergent are twofold. The first is the physical effect of strengthening the water swelling The role of clothing so that the more easily fall off the grime, the second is chemical, oil stains on clothing and alkaline washing solution from the saponification reaction to form a water-soluble compounds, dissolved in water, in order to speed up the clothes off, but also the use of washing machines Physical function, so that the washing liquid and clothing in the relative movement of the centrifugal effect, the waste on the clothes effectively separated. The factors that affect the cleaning effect are many, first of all
