Ibisa nibitandukanyirizo byibikoresho bishya byavunitse byahinduwe na silicon kaseti hamwe na mika kaseti (2)

Mu myaka yashize, ubwoko bushya bwibikoresho bivunika - ceramic refractory silicone rubber na ceramic refractory silicone rubber composite umukandara bikoreshwa mugukora insinga zivunika, ahanini zikemura ibibazo byubwoko bubiri bwavuzwe haruguruinsinga zangiritse.

1. Ibiranga ceramic refractory silicone rubber

Ceramic refractory silicone reberi ikorwa hongerwamo ibikoresho bikora mubushyuhe bwo hejuru bwo hejuru (HTV) silicone rubber.Kurwanya ubushyuhe bwo hejuru kandi buke, kurwanya gusaza kwa ozone, kurwanya gusaza kwikirere, imikorere myiza yumuriro wamashanyarazi nibikorwa byiza byo gutunganya;munsi yubushyuhe bwo hejuru bwo gutwika umuriro, silicone rubber compte ivanze yongewemo nibikoresho bikora ikora urwego rukomeye rwo kurinda ibirwanisho bya ceramic, Irashobora kugira uruhare mukwitandukanya numuriro, gukumira umuriro, kubika, kubika ubushyuhe, kubika amazi no kurwanya umutingito, bityo bikagenda neza umuvuduko w'amashanyarazi n'itumanaho mugihe habaye umuriro.

2. Uburyo bwo kurwanya umuriro no kurwanya umuriro wa ceramic refractory silicone rubber

Ibikoresho bisanzwe bya polymer bihinduka ivu nyuma yo gukuraho flame, kandi ntibishobora guhinduka mubintu byubutaka;ceramic fireproof hamwe na rebero ya silicone reberi irashobora gucumurwa mubushyuhe bwo hejuru butagira umuriro hejuru ya 500°C no gutwika umuriro hejuru ya 620°C. Igihe kinini cyo kwiyuhagira hamwe nubushyuhe bwo hejuru, niko bigaragara ingaruka za ceramisation, kandi ubushyuhe bwo gukuraho bushobora kugera kuri 3000℃;ceramicized fire-anti-fire silicone reberi irashobora gukorwa hifashishijwe ibikoresho bisanzwe byo gutunganya reberi.Igicuruzwa cyarangiye gifite ibintu byose bya reberi ya silicone kandi bifite imikorere myiza.

Nibikoresho byinshi bishobora kuba farashi mubushyuhe bwinshi wongeyeho reberi ya silicone.Ikomeza ibintu byose biranga silicone reberi mubushyuhe bwicyumba.Iyo uhuye nubushyuhe bwo hejuru butagira umuriro hejuru ya 500℃no gutwika umuriro hejuru ya 620℃, bizahindurwa mubutaka butemewe.Ubu bwoko bwibikoresho bya ceramic bifite ibyiza byo kubika ceramic, kubika ubushyuhe, kubika umuriro, kubika amazi, kurwanya ihungabana, no gutakaza ibiro bito.

Ceramic irwanya umuriro kandi itavunika silicone reberi ntabwo ari uburozi kandi nta mpumuro nziza mubushyuhe bwicyumba, ifite ubworoherane nubworoherane, hamwe nubushuhe buhebuje hamwe no kurwanya amazi.Ifite ibiranga reberi ya silicone.Ceramic refractory silicone reberi irashobora gutwikwa numuriro Nyuma yo gutwika muminota 2-4, itangira gucengera mumashanyarazi akomeye asa na ceramic.Igikoresho cyiziritse cyiki ceramic kimeze nkigikonoshwa gishobora kubuza neza umuriro gukomeza gutwika;kandi iracika rwose nyuma yo gutwikwa muminota igera kuri 2.Umwotsi, muburyo bukurikira bwo gukuraho, nta mwotsi ubwawo uzabyara;umwotsi wabyaye mu minota 2 yambere nabwo nta halogene, idafite uburozi, kandi ntacyo bitwaye;umwotsi ni umwotsi ukomeye utangwa nyuma yo gutwikwa na silikoni kama, ibikoresho bya ceramic byatwitswe bisa nigikonjo gikomeye kandi kimwe.Ikintu nkiki gifite ubwiza buhebuje, kubika ubushyuhe, kurwanya umuriro no kurwanya umuriro, kandi birashobora no kwihanganira ihungabana no kunyeganyega, kandi bikarinda amazi kwinjira.Iremeza neza umurongo kumurongo mugihe cyo gutera no kunyeganyega.

Ceramic refractory silicone rubber ikomatanya umukandara

Ceramic refractory silicone rubber compte kaseti ikorwa muguhuza ceramic ceramic yumuriro hamwe na silicone ya silicone ya reberi kumyenda ya fibre fibre idashobora kwihanganira ubushyuhe bukabije ukurikije umubyimba runaka binyuze muburyo bwo guhuza, nyuma yo kuyikata, no kuyizinga ku muriro utazimya umuriro. insinga na kabili.

Ibiranga ceramic refractory silicone reberi na ceramic refractory silicone rubber ikomatanya umukandara:

1. Gukwirakwiza amashanyarazi meza cyane: birashobora kugera kumashanyarazi ya XLPE na EPDM: kwihanganira amajwi bishobora kugera kuri 2×1015Ω ·cm, imbaraga zo gusenyuka 22-25KV / mm, gutakaza dielectric tangent 10-3, guhora dielectricδ: 2-3.5, irashobora gukoreshwa mugukingira;

2. Kurwanya ubushyuhe buhebuje kandi buke: ubushyuhe bwigihe kirekire -70 ~ 200°C, ubuzima bwa serivisi bushobora kugera kumyaka 5-50 ukurikije ibidukikije bitandukanye;itangiye gukomera hejuru ya 350°C, kandi irashobora gukoreshwa igihe kirekire mubidukikije bihagaze;

3. Kurwanya imirasire ya ozone na ultraviolet: nta mpamvu yo kongeramo imiti igabanya ubukana na antioxydants, kandi ubuzima bwa serivisi bushobora kugera ku myaka irenga 30-50 mubushyuhe bwicyumba;

4. Imiterere yihariye y'ubutaka: igipimo cyo kwinjiza amazi 0.17%, hamwe na hygroscopique nkeya cyane no kwinjiza amazi, imikorere myiza yo kurwanya indwara ya mildew, kudafatana ibikoresho byinshi;

5. Ibidukikije byangiza ibidukikije: nta halogene, idafite ibyuma biremereye, bidafite uburozi, uburyohe, kandi nta ngaruka bigira ku mubiri w’umuntu no ku bidukikije;

6. Kurwanya ruswa ya chimique nziza, kutirinda amazi no kurwanya amavuta;

7. Hydrophobicite nziza, kurwanya umwanda wa flashover no kurwanya ibimera;

8. Imikorere myiza yo gutunganya: byoroshye gutunganya nko kuvanga, gukora, kalendari, gukuramo, kubumba, nibindi, kandi amazi yibikoresho bya reberi nibyiza;

9. Ubumara bwumwotsi nicyiciro cyo hejuru cya ZA1 mubikoresho bya polymer, cyane cyane ibikoresho bya kabili, ni ukuvuga umwotsi nyuma yo gutwikwa uhumeka nimbeba muminota 30, kandi nta gihinduka muminsi itatu;

10. Gukwirakwiza ubushyuhe bwiza, ubushyuhe bwumuriro 0.09W / Mk, cyane cyane nyuma yo gukuraho, imbere ni imiterere yubuki bumwe, bufite imbaraga zo kurwanya umuriro no kubika ubushyuhe;

11. Kubuza flame nziza: kutagira umuriro birashobora kugera kurwego rwa UL94V-0, igipimo cya ogisijeni kiri hejuru ya 28, naho hejuru irashobora kugera hejuru ya 40.5;

12. Nyuma yo gutwikwa nubushyuhe bwo hejuru, irashobora kurasa muburyo bwa ceramic kugirango ikore ibirwanisho bikomeye bya ceramic kugirango irinde imigendere myiza yumuzunguruko.Nibintu "byimpinduramatwara" cyane biranga ceramic irwanya umuriro na silicone reberi.Ubushyuhe buri hejuru, igihe kinini cyo gukuraho, hamwe nintwaro za ceramic Birakomeye umubiri;nibyiza kuruta mika kaseti, iba ikomeye kandi igacika nyuma yo gutwikwa ikagwa byoroshye;

13. Umuyoboro hamwe n’insinga birwanya umuriro n’umugozi wakozwe na ceramic itazimya umuriro hamwe na silicone irwanya umuriro hamwe na ceramic yumuriro wumuriro hamwe na silicone reberi ikomatanya kaseti irashobora kugera ku rwego rwa A urwego rwa GB12666.6, ni ukuvuga, gutwika mumuriro wa 950 ~ 1000℃kuri 90min, 3A fuse Nta guhuza;irashobora kandi kugera ku rwego rwo hejuru rwa CWZ yo mu Bwongereza BS6387, ni ukuvuga C.-gutwika mu muriro kuri 950°C kumasaha 3, W.-gutera amazi, Z.-kunyeganyega;

14. Ubucucike buto (1.42-1.45), igiciro gito nigikorwa kinini;

15. Ukurikije ibimaze kuvugwa haruguru, irashobora gusimbuza burundu kaseti ya mika, ntabwo ari iy'umuriro wa voltage nkeya irwanya umuriro ndetse n’insinga zidashobora kuzimya umuriro, ariko kandi no ku nsinga ziciriritse n’umuriro mwinshi hamwe n’insinga n’insinga.
