1. Iipropati zezinto zesilicone
1.1 Ukwakhiwa kweekhemikhali kunye nolwakhiwo lweemolekyuli
I-Silicone yinto enezinto ezixutywe ngamakhemikhali kunye nesakhiwo se-molecular. Icandelo layo eliphambili yi-silicon dioxide (SiO₂), edla ngokubakho ngendlela ye-polymer. Ngokwembono yekhemikhali, yenziwe ngee-athomu ze-silicon kunye nee-athomu ze-oksijini ezidityanisiweyo ukuze zenze i-skeleton esisiseko. Ii-athomu ze-silicon zikwadityaniswe namaqela e-organic, afana ne-methyl (-CH₃), anika i-silicone iipropati ezahlukeneyo zomphezulu kunye neempawu zomzimba nezekhemikhali. Ulwakhiwo lwayo lwe-molecular lulwakhiwo lwenethiwekhi okanye oluthe ngqo. Ulwakhiwo lwenethiwekhi ye-silicone lunoxinano oluphezulu oludibanisa kwaye lubonisa amandla kunye nozinzo oluhle loomatshini, ngelixa ulwakhiwo oluthe ngqo lwe-silicone kulula ukulucubungula nokuyila. Olu lwakhiwo lwekhemikhali olukhethekileyo kunye nesakhiwo se-molecular zenza i-silicone yahluke kwezinye izinto ngokweempawu zomzimba ezifana ne-friction coefficient, enika isiseko sokufunda i-friction coefficient yayo kwimeko emanzi.

2. Izinto ezichaphazela i-frictional coefficient
2.1 Uburhabaxa bomphezulu
Uburhabaxa bomphezulu bunempembelelo ebalulekileyo kwi-coefficient yokungqubana kweii-silicone hip padskwimeko yokumanzi. Izifundo zibonise ukuba xa uburhabaxa bomphezulu bunyuka ukusuka kwi-0.1 microns ukuya kwi-1 micron, i-friction coefficient iyancipha malunga ne-15%. Oku kungenxa yokuba iindawo ezirhabaxa zinokwenzeka ukuba zenze iifilimu zamanzi ezincinci kwimeko yokumanzi, zinciphise indawo yoqhagamshelwano kwaye ngaloo ndlela zinciphise ukungqubana.

Iimolekyuli zamanzi ziya kwenza ifilimu yamanzi kumphezulu we-silicone, kwaye ubukhulu kunye nokuzinza kwale filimu yamanzi kuchaphazela ngokuthe ngqo i-friction coefficient. Xa iimolekyuli zamanzi zifakwe kumphezulu we-silicone, ziya kusebenzisana namaqela e-siloxane (-Si-O-) kumphezulu we-silicone ukuze zenze ii-hydrogen bonds. Ukwakheka kwale hydrogen bond kwenza iimolekyuli zamanzi zicwangciswe kakuhle kumphezulu we-silicone, ngaloo ndlela zidlala indima yokuthambisa ukuya kwinqanaba elithile. Izifundo zibonise ukuba xa uxinzelelo lweemolekyuli zamanzi luphakathi, ubukhulu befilimu yamanzi eyenziweyo bumalunga ne-100 nanometers, kwaye i-friction coefficient ye-silicone hip pad iya kuncipha kakhulu.

Umzekelo, xa umswakama ohambelanayo ungama-30%, i-friction coefficient ye-silicone hip pad xa idibana nolusu lomntu imalunga ne-0.3. Njengoko umswakama ohambelanayo usanda, inani leemolekyuli zamanzi ezifakwe kumphezulu we-silicone liyanda, ubukhulu befilimu yamanzi buyanda kancinci kancinci, kwaye i-friction coefficient iyancipha kancinci kancinci. Xa umswakama ohambelanayo ufikelela kuma-60% - 80%, i-friction coefficient ye-silicone hip pad ifikelela kwixabiso eliphantsi, malunga ne-0.1 - 0.15. Ngaphakathi kolu luhlu, iimolekyuli zamanzi zinokwenza ifilimu yamanzi ezinzileyo, enciphisa ngokufanelekileyo indawo yoqhagamshelwano kunye nokunamathelana phakathi komphezulu we-silicone nento eqhagamshelanayo.
Nangona kunjalo, xa umswakama ohambelanayo uqhubeka unyuka kwaye udlula i-80%, i-friction coefficient iya kunyuka kwakhona. Oku kungenxa yokuba umswakama ophezulu kakhulu uya kubangela ukuba umphezulu we-silicone ufunxe iimolekyuli zamanzi ezininzi kwaye wenze ifilimu yamanzi etyebileyo kakhulu. Ifilimu yamanzi etyebileyo kakhulu iya kwenza umphezulu we-silicone utyibilike kakhulu, nto leyo eya kwandisa ukumelana kokutyibilika kwento eqhagamshelanayo kumphezulu we-silicone. Umzekelo, xa umswakama ohambelanayo ungama-90%, i-friction coefficient ye-silicone hip pad xa idibana nolusu lomntu iya kunyuka iye malunga ne-0.2.
