Mafuwa a mtundu wa belu

Chidule:
Ziwiya za mtundu wa belu zimagwiritsidwa ntchito makamaka poyatsira ndi kutentha, kotero ndi ziwiya zotentha zosiyanasiyana nthawi ndi nthawi. Kutentha kumakhala pakati pa 650 ndi 1100 ℃ nthawi zambiri, ndipo kumasintha nthawi yomwe yatchulidwa mu dongosolo lotenthetsera. Kutengera ndi kudzaza kwa ziwiya za mtundu wa belu, pali mitundu iwiri: ng'anjo yamtundu wa belu ndi ng'anjo yozungulira ya mtundu wa belu. Magwero a kutentha kwa ziwiya zamtundu wa belu nthawi zambiri amakhala gasi, kutsatiridwa ndi magetsi ndi mafuta opepuka. Kawirikawiri, ziwiya zamtundu wa belu zimakhala ndi magawo atatu: chivundikiro chakunja, chivundikiro chamkati, ndi chitofu. Chipangizo choyatsira nthawi zambiri chimayikidwa pachivundikiro chakunja chotetezedwa ndi kutentha, pomwe zida zogwirira ntchito zimayikidwa pachivundikiro chamkati kuti zitenthe ndi kuziziritsa.

Ziwiya zamtundu wa belu zimakhala ndi mpweya wabwino, kutentha kochepa, komanso kutentha kwambiri. Komanso, sizifunikira chitseko cha ng'anjo kapena njira yonyamulira ndi njira zina zosiyanasiyana zotumizira maginito, kotero zimasunga ndalama ndipo zimagwiritsidwa ntchito kwambiri mu ziwiya zotenthetsera kutentha za zinthu zogwirira ntchito.
Zofunikira ziwiri zofunika kwambiri pa zipangizo zophikira mu uvuni ndi kulemera kochepa komanso kugwiritsa ntchito mphamvu moyenera kwa zophimba zotenthetsera.

Mavuto ofala ndi refracto yachikhalidwe yopepukanjerwa za ry kapena st yopepuka yopoteraMapangidwe akuphatikizapo:

1. Zipangizo zopopera mphamvu zokhala ndi mphamvu yaikulu (nthawi zambiri njerwa zopopera mphamvu zopepuka zimakhala ndi mphamvu yeniyeni ya 600KG/m3 kapena kuposerapo; zopopera mphamvu zopepuka zimakhala ndi 1000 KG/m3 kapena kuposerapo) zimafuna katundu wambiri pa kapangidwe ka chitsulo cha chivundikiro cha ng'anjo, kotero kugwiritsidwa ntchito kwa kapangidwe ka chitsulo ndi ndalama zomwe zimagwiritsidwa ntchito pomanga ng'anjo kumawonjezeka.

2. Chivundikiro chakunja chachikulu chimakhudza mphamvu yonyamulira ndi malo a pansi pa malo opangira zinthu.

3. Ng'anjo ya mtundu wa belu imagwira ntchito pa kutentha kosiyanasiyana, ndipo njerwa zopepuka zosagwira ntchito kapena zopepuka zotayidwa zimakhala ndi mphamvu yayikulu yotenthetsera, kutentha kwambiri, komanso kugwiritsa ntchito mphamvu zambiri.

Komabe, zinthu zopangidwa ndi ulusi wosasunthika wa CCEWOOL zimakhala ndi kutentha kochepa, kutentha kochepa, komanso kuchuluka kochepa kwa voliyumu, zomwe ndi zifukwa zazikulu zomwe zimathandizira kuti zigwiritsidwe ntchito kwambiri pophimba zotenthetsera. Makhalidwe ake ndi awa:

1. Kutentha kwakukulu kogwira ntchito ndi mitundu yosiyanasiyana yogwiritsira ntchito
Ndi chitukuko cha kupanga ndi ukadaulo wa ulusi wa ceramic wa CCEWOOL, zinthu za ulusi wa ceramic wa CCEWOOL zafika pa serialization ndi functionality. Ponena za kutentha, zinthuzi zimatha kukwaniritsa zofunikira za kutentha kosiyanasiyana kuyambira 600 ℃ mpaka 1500 ℃. Ponena za mawonekedwe, zinthuzi pang'onopang'ono zapanga zinthu zosiyanasiyana zopangira zinthu zina monga thonje lachikhalidwe, mabulangeti, zinthu za felt mpaka ma module a ulusi, matabwa, ziwalo zapadera, mapepala, nsalu za ulusi ndi zina zotero. Zitha kukwaniritsa mokwanira zofunikira za uvuni zamafakitale pazinthu za ulusi wa ceramic m'mafakitale osiyanasiyana.
2. Kuchuluka kochepa kwa voliyumu:
Kuchuluka kwa zinthu zopangidwa ndi ulusi wa ceramic nthawi zambiri kumakhala 96 ~ 160kg/m3, zomwe ndi pafupifupi 1/3 ya njerwa zopepuka ndi 1/5 ya zinthu zopepuka zotayidwa. Pa ng'anjo yatsopanoyi, kugwiritsa ntchito zinthu zopangidwa ndi ulusi wa ceramic sikungopulumutsa chitsulo chokha, komanso kumapangitsa kuti katundu/kutsitsa katundu ndi kunyamula zikhale zosavuta, zomwe zimapangitsa kuti ukadaulo wa ng'anjo ya mafakitale upite patsogolo.
3. Kutentha pang'ono komanso malo osungira kutentha:
Poyerekeza ndi njerwa zopingasa ndi njerwa zoteteza kutentha, mphamvu ya zinthu zopangidwa ndi ulusi wa ceramic ndi yotsika kwambiri, pafupifupi 1/14-1/13 ya njerwa zopingasa ndi 1/7-1/6 ya njerwa zoteteza kutentha. Pa ng'anjo ya belu yomwe imagwiritsidwa ntchito nthawi ndi nthawi, mafuta ambiri omwe sagwiritsidwa ntchito popanga zinthu amatha kusungidwa.
4. Kapangidwe kosavuta, kanthawi kochepa
Popeza mabulangeti ndi ma module a ulusi wa ceramic ali ndi kusinthasintha kwabwino, kuchuluka kwa kupsinjika kumatha kunenedweratu, ndipo palibe chifukwa chosiya malo olumikizirana panthawi yomanga. Chifukwa chake, kapangidwe kake ndi kosavuta komanso kosavuta, komwe kumatha kumalizidwa ndi antchito aluso nthawi zonse.
5. Kugwira ntchito popanda uvuni
Pogwiritsa ntchito ulusi wonse, ng'anjo zimatha kutenthedwa mofulumira kufika kutentha kwa ndondomekoyi ngati sizikuletsedwa ndi zigawo zina zachitsulo, zomwe zimapangitsa kuti kugwiritsa ntchito bwino ng'anjo zamafakitale kukhale bwino komanso kuchepetsa kugwiritsa ntchito mafuta osakhudzana ndi kupanga.
6. Kutentha kochepa kwambiri
Ulusi wa ceramic ndi kuphatikiza kwa ulusi wokhala ndi mainchesi a 3-5um, kotero umakhala ndi kutentha kochepa kwambiri. Mwachitsanzo, pamene bulangeti la ulusi wa aluminiyamu wokhala ndi kuchuluka kwa 128kg/m3 lifika pa 1000℃ pamalo otentha, coefficient yake yotumizira kutentha ndi 0.22(W/MK) yokha.
7. Kukhazikika kwa mankhwala abwino komanso kukana kukokoloka kwa mpweya:
Ulusi wa ceramic ukhoza kusungunuka mu phosphoric acid, hydrofluoric acid, ndi hot alkali, ndipo umakhala wokhazikika kuzinthu zina zowononga. Kuphatikiza apo, ma module a ulusi wa ceramic amapangidwa popinda mabulangeti a ulusi wa ceramic mosalekeza pamlingo winawake wopsinjika. Pambuyo poti pamwamba pake pakonzedwa, kukana kukokoloka kwa nthaka kumatha kufika 30m/s.
