Izinto ezisetshenziswa kakhulu emkhakheni wokushisa: Izinto ezihlanganisiwe ze-C/C

Izinhlanganisela zekhabhoni-khabhoniziwuhlobo lwezinhlanganisela ze-carbon fiber, ezine-carbon fiber njengezinto zokuqinisa kanye ne-carbon ebekwe njengezinto ze-matrix. I-matrix yeIzinhlanganisela ze-C/C ziyi-carbonNjengoba cishe yakhiwe ngokuphelele nge-carbon elemental, inokumelana okuhle kakhulu nokushisa okuphezulu futhi izuza ifa lezakhiwo eziqinile ze-carbon fiber. Yake yathuthukiswa emkhakheni wokuzivikela ngaphambilini.

Izindawo zokufaka isicelo:

Izinto ezihlanganisiwe ze-C/Czitholakala phakathi nochungechunge lwezimboni, kanti oluphezulu luhlanganisa ukukhiqizwa kwe-carbon fiber kanye ne-preform, kanti amasimu okusetshenziswa aphansi abanzi kakhulu.Izinto ezihlanganisiwe ze-C/Czisetshenziswa kakhulu njengezinto ezingamelani nokushisa, izinto zokungqubuzana, kanye nezinto zokusebenza kahle kwemishini. Zisetshenziswa ezindiza (izintambo zomphimbo we-rocket nozzle, izinto zokuvikela ukushisa kanye nezingxenye zesakhiwo sokushisa kwenjini), izinto zokubopha (isitimela esinejubane eliphezulu, amadiski amabhuleki endiza), amasimu okushisa e-photovoltaic (imiphongolo yokushisa, izitsha zokushisa, amashubhu okuqondisa nezinye izingxenye), imizimba yezinto eziphilayo (amathambo okwenziwa) kanye neminye imikhakha. Njengamanje,Izinto ezihlanganisiwe ze-C/CIzinkampani zigxila kakhulu ekuxhumaneni okukodwa kwezinto ezihlanganisiwe futhi zinwebeka esiqondisweni sokuqala kwesimo.

Izinto ezihlanganisiwe ze-C/C zisebenza kahle kakhulu, zinobukhulu obuphansi, amandla aphezulu athile, i-modulus ephezulu ethile, ukuhanjiswa okuphezulu kokushisa, i-coefficient yokukhulisa ukushisa ephansi, ukuqina okuhle kokuqhekeka, ukumelana nokuguguleka, ukumelana nokususwa kwegesi, njll. Ikakhulukazi, ngokungafani nezinye izinto, amandla ezinto ezihlanganisiwe ze-C/C ngeke anciphe kodwa anganda ngokwanda kwezinga lokushisa. Ziyinto enhle kakhulu engamelani nokushisa, ngakho-ke ziye zaqala ukwenziwa zibe yizimboni kuma-rocket throat liners.

Izinto ezihlanganisiwe ze-C/C zizuza njengefa izakhiwo ezinhle kakhulu zemishini kanye nezakhiwo zokucubungula ze-carbon fiber, futhi zinokumelana nokushisa kanye nokumelana nokugqwala kwe-graphite, futhi sezibe ngumncintiswano oqinile wemikhiqizo ye-graphite. Ikakhulukazi ensimini yokufaka enezidingo zamandla aphezulu - insimu yokushisa ye-photovoltaic, ukusebenza kahle kwezindleko kanye nokuphepha kwezinto ezihlanganisiwe ze-C/C kuya ngokuya kugqama ngaphansi kwama-silicon wafer amakhulu, futhi sekuyinto efunwa kakhulu. Ngokuphambene nalokho, i-graphite isibe isengezo sezinto ezihlanganisiwe ze-C/C ngenxa yomthamo wokukhiqiza olinganiselwe ohlangothini lokuphakelwa.

Ukusetshenziswa kwensimu yokushisa ye-Photovoltaic:

Insimu yokushisa iyisistimu yonke yokugcina ukukhula kwe-silicon e-monocrystalline noma ukukhiqizwa kwama-ingots e-silicon e-polycrystalline ekushiseni okuthile. Idlala indima ebalulekile ekuhlanzekeni, ukufana kanye nezinye izimfanelo ze-silicon e-monocrystalline kanye ne-silicon e-polycrystalline, futhi iyingxenye engaphambili yomkhakha wokukhiqiza i-silicon e-crystalline. Insimu yokushisa ingahlukaniswa ibe uhlelo lwensimu yokushisa lwe-silicon e-monocrystalline single crystal pulling furnace kanye nohlelo lwensimu yokushisa lwe-polycrystalline ingot furnace ngokohlobo lomkhiqizo. Njengoba amaseli e-silicon e-monocrystalline enekhono eliphezulu lokuguqulwa kunamaseli e-silicon e-polycrystalline, isabelo semakethe sama-wafers e-silicon e-monocrystalline siyaqhubeka nokukhula, kuyilapho isabelo semakethe sama-wafers e-silicon e-polycrystalline ezweni lakithi besilokhu sincipha unyaka nonyaka, sisuka ku-32.5% ngo-2019 saya ku-9.3% ngo-2020. Ngakho-ke, abakhiqizi bensimu yokushisa basebenzisa kakhulu indlela yobuchwepheshe bensimu yokushisa yama-ovens e-single crystal pulling.

Umfanekiso 2: Insimu yokushisa ochungechungeni lwemboni yokukhiqiza ye-silicon ekristali

Insimu yokushisa yakhiwe yizingxenye ezingaphezu kweshumi nambili, kanti izingxenye ezine eziyinhloko yi-crucible, i-guide tube, i-insulation cylinder, kanye ne-heater. Izingxenye ezahlukene zinezidingo ezahlukene zezakhiwo zezinto ezibonakalayo. Isithombe esingezansi siwumdwebo we-schematic wensimu yokushisa ye-single crystal silicon. I-crucible, i-guide tube, kanye ne-insulation cylinder yizingxenye zesakhiwo zesistimu yensimu yokushisa. Umsebenzi wazo oyinhloko ukusekela yonke insimu yokushisa ephezulu, futhi zinezidingo eziphezulu zobuningi, amandla, kanye nokuqhuba ukushisa. I-heater iyisici sokushisa ngqo ensimini yokushisa. Umsebenzi wayo ukunikeza amandla okushisa. Ngokuvamile iyamelana, ngakho-ke inezidingo eziphakeme zokumelana nezinto ezibonakalayo.
