Izinto zokushintsha isigaba (ama-PCM) zingahlukaniswa zibe izigaba eziningana ngokusekelwe ekwakhekeni kwamakhemikhali azo kanye nezici zokushintsha kwesigaba, ngayinye enezinzuzo nemikhawulo ethile yohlelo lokusebenza.Lezi zinto zibandakanya ikakhulukazi ama-PCM aphilayo, ama-PCM angaphili, ama-PCM asuselwa ku-bio, nama-PCM ayinhlanganisela.Ngezansi yisingeniso esinemininingwane yezimpawu zohlobo ngalunye lwezinto ezishintsha isigaba:
1. Izinto zokushintsha isigaba se-Organic
Izinto zokushintsha isigaba se-organic zihlanganisa ikakhulukazi izinhlobo ezimbili: upharafini nama-fatty acids.
- Upharafini:
-Izici: Ukuzinza kwamakhemikhali okuphezulu, ukusebenziseka kabusha okuhle, nokulungiswa kalula kwendawo encibilikayo ngokushintsha ubude bamaketanga wamangqamuzana.
-I-Disadvantage: I-conductivity eshisayo iphansi, futhi kungase kudingeke ukwengeza izinto zokuhambisa ezishisayo ukuze kuthuthukiswe isivinini sokuphendula esishisayo.
- Amafutha acid:
-Izici: Inokushisa okucashile okuphakeme kunopharafini kanye nendawo ebanzi yokuncibilika, ifanele izidingo ezihlukahlukene zokushisa.
-Okubi: Amanye ama-acids anamafutha angase ahlukaniswe ngezigaba futhi abiza kakhulu kunopharafini.
2. Izinto zokushintsha isigaba sezinto ezingaphili
Izinto zokushintsha isigaba sezinto ezingaphili zihlanganisa izixazululo ezinosawoti kanye nosawoti wensimbi.
-Isixazululo samanzi anosawoti:
-Izici: Ukuzinza okuhle kokushisa, ukushisa okucashile okuphezulu, nezindleko eziphansi.
-Ukungalungi: Ngesikhathi sokuqhwa, i-delamination ingase ivele futhi idle, idinga izinto zesitsha.
-Metal usawoti:
-Izici: Izinga lokushisa lokushintsha kwesigaba esiphezulu, lilungele ukugcina amandla okushisa aphezulu.
-Ukungalungi: Kukhona nezinkinga zokugqwala futhi ukuwohloka kokusebenza kungenzeka ngenxa yokuncibilika okuphindaphindiwe nokuqina.
3. Izinto ezisetshenziswayo zokushintsha isigaba sezinto eziphilayo
Izinto zokushintsha isigaba se-Biobased zingama-PCM akhishwe emvelweni noma ahlanganiswe nge-biotechnology.
-Izici:
-Inobungani nemvelo, iyabola, ayinazo izinto eziyingozi, ehlangabezana nezidingo zentuthuko esimeme.
-Ingakhishwa ezintweni ezingavuthiwe zezitshalo noma zezilwane, njengamafutha emifino namafutha ezilwane.
-Ukubi:
-Kungase kube nezinkinga ngezindleko eziphezulu kanye nokulinganiselwa komthombo.
-Ukuzinza kwe-thermal kanye ne-thermal conductivity kuphansi kune-PCM yendabuko, futhi kungadinga ukuguqulwa noma ukusekelwa kwezinto ezihlanganisiwe.
4. Izinto zokushintsha isigaba esiyinhlanganisela
Izinto zokushintsha isigaba esihlanganisiwe zihlanganisa ama-PCM nezinye izinto (njengezinto ezishisayo ezishisayo, izinto zokusekela, njll.) ukuze kuthuthukiswe izakhiwo ezithile zama-PCM akhona.
-Izici:
-Ngokuhlanganisa nezinto eziphezulu ze-thermal conductivity, isivinini sokuphendula esishisayo kanye nokuzinza kokushisa kungathuthukiswa kakhulu.
-Ukwenza ngokwezifiso kungenziwa ukuze kuhlangatshezwane nezidingo ezithile zohlelo lokusebenza, njengokuthuthukisa amandla emishini noma ukuthuthukisa ukuzinza kwe-thermal.
-Ukubi:
-Inqubo yokulungiselela ingase ibe yinkimbinkimbi futhi ibize.
-Kudingeka izindlela eziqondile zokuqhathanisa nezokucutshungulwa kwempahla.
Lezi zinto zokushintsha kwesigaba ngayinye inezinzuzo zayo ezihlukile kanye nezimo zohlelo lokusebenza.Ukukhethwa kohlobo olufanele lwe-PCM ngokuvamile kuncike ezidingweni ezithile zokushisa zohlelo lokusebenza, isabelomali sezindleko, ukucatshangelwa komthelela wendawo, nempilo yesevisi elindelekile.Ngokujula kocwaningo kanye nokuthuthukiswa kobuchwepheshe, ukuthuthukiswa kwezinto zokushintsha isigaba
Ububanzi besicelo kulindeleke ukuthi buqhubeke nokunwetshwa, ikakhulukazi ekugcinweni kwamandla nasekulawuleni izinga lokushisa.
