Izinto zokutshintsha iSigaba (i-PCMs) zinokuhlulwa zibe ziindidi ezininzi ngokusekwe kubume bemichiza kunye neempawu zokutshintsha kwesigaba, ngasinye sineengenelo ezithile zesicelo kunye nemida.Ezi zixhobo ziquka ii-PCM zendalo, iiPCM ezingaphiliyo, iiPCM ezisekwe kwibio, kunye neePCM ezihlanganisiweyo.Apha ngezantsi kukho isingeniso esineenkcukacha kwiimpawu zodidi ngalunye lwezixhobo zokutshintsha isigaba:
1. Izinto zokutshintsha isigaba se-Organic
Izinto zokutshintsha isigaba se-Organic ziquka iindidi ezimbini: iparafini kunye ne-fatty acids.
-Parafini:
-Iimpawu: Ukuzinza kweekhemikhali eziphezulu, ukuphinda kusetyenziswe kakuhle, kunye nokulungelelaniswa lula kwendawo yokunyibilika ngokuguqula ubude bamatyathanga e-molecular.
-I-Disadvantage: I-conductivity ye-thermal iphantsi, kwaye kunokufuneka ukuba ungeze izinto zokuqhuba i-thermal ukuze kuphuculwe isantya sokuphendula nge-thermal.
Iiasidi ezinamafutha:
-Iimpawu: Inobushushu obufihlakeleyo obuphezulu kuneparafini kunye nendawo ebanzi yokunyibilika, ilungele iimfuno ezahlukeneyo zobushushu.
-Izinto ezingeloncedo: Ezinye iiasidi ezinamafutha zisenokwahlulwa ngokwesigaba kwaye zibiza kakhulu kuneparafini.
2. Izinto zokutshintsha isigaba se-Inorganic
Izinto zokutshintsha isigaba se-Inorganic ziquka izisombululo ze-saline kunye neetyuwa zetsimbi.
-Isisombululo samanzi etyuwa:
-Iimpawu: Uzinzo oluhle lwe-thermal, ukushisa okufihlakeleyo okuphezulu, kunye neendleko eziphantsi.
-Izinto ezingeloncedo: Ngexesha lokukhenkceza, i-delamination inokuthi yenzeke kwaye iyadleka, ifuna izixhobo zesikhongozeli.
-Iityuwa zesinyithi:
-Iimpawu: Ubushushu besigaba esiphakamileyo sokutshintsha, silungele ukugcinwa kwamandla obushushu aphezulu.
-Izinto ezingeloncedo: Kukwakho nemiba yomhlwa kunye nokuthotywa komgangatho wokusebenza kungenzeka ngenxa yokunyibilika okuphindaphindiweyo kunye nokuqina.
3. Izinto zokutshintsha isigaba se-Biobased
Izinto zokutshintsha isigaba se-Bio-based zi-PCM ezikhutshwe kwindalo okanye zenziwe nge-biotechnology.
-Iimbonakalo:
-Inobuhlobo kwindalo, iyabola, ayinazinto ezinobungozi, ikhawulelana neemfuno zophuhliso oluzinzileyo.
-Inokukhutshwa kwizityalo okanye kwizilwanyana eziluhlaza, ezifana neoli yemifuno kunye namafutha ezilwanyana.
-Izinto ezingeloncedo:
-Kunokubakho imiba eneendleko eziphezulu kunye nokunciphisa umthombo.
-I-thermal stability kunye ne-thermal conductivity iphantsi kune-PCM zendabuko, kwaye inokufuna ukuguqulwa okanye ukuxhaswa kwezinto ezidibeneyo.
4. Izinto zokutshintsha isigaba esihlanganisiweyo
Izinto eziguqukayo zesigaba esihlanganisiweyo zidibanisa ii-PCM kunye nezinye izinto (ezifana nezixhobo zokuqhuba i-thermal, izinto ezixhasayo, njl.) Ukuphucula iimpawu ezithile ze-PCM ezikhoyo.
-Iimbonakalo:
-Ngokudibanisa nezinto eziphezulu ze-thermal conductivity, isantya sokuphendula i-thermal kunye nokuzinza kwe-thermal kunokuphuculwa kakhulu.
-Ukwenziwa ngokwezifiso kunokwenziwa ukuhlangabezana neemfuno ezithile zesicelo, njengokuphucula amandla omatshini okanye ukuphucula ukuzinza kwe-thermal.
-Izinto ezingeloncedo:
-Inkqubo yokulungiselela inokuba nzima kwaye ibiza kakhulu.
-Izixhobo ezichanekileyo zokuthelekisa kunye nobuchule bokusebenza ziyafuneka.
Ezi zixhobo zokutshintsha kwesigaba ngasinye zineenzuzo zazo ezizodwa kunye neemeko zesicelo.Ukhetho lodidi olufanelekileyo lwePCM ludla ngokuxhomekeke kwiimfuno zobushushu besicelo esithile, uhlahlo lwabiwo-mali lweendleko, iingqwalasela zempembelelo yokusingqongileyo, kunye nobomi benkonzo obulindelekileyo.Ngokunzulu kophando kunye nophuhliso lwetheknoloji, ukuphuhliswa kwezinto zokutshintsha isigaba
Umda wesicelo kulindeleke ukuba uqhubele phambili ukwandisa, ngakumbi kugcino lwamandla kunye nolawulo lobushushu.
