Isingeniso
Ezikhumulweni zezindiza, ezibhedlela, ezikhungweni zezitolo, ezitimeleni ezingaphansi komhlaba, ezakhiweni eziphakeme nezinye izindawo ezibalulekile, ukuze kuqinisekiswe ukuphepha kwabantu uma kwenzeka umlilo kanye nokusebenza okujwayelekile kwezinhlelo eziphuthumayo, kuyadingeka ukusebenzisa ucingo olungashi. kanye nekhebula elinokumelana nomlilo okuhle kakhulu. Ngenxa yokunakwa okwandayo kokuphepha komuntu siqu, isidingo semakethe samakhebuli angashi futhi siyakhula, futhi izindawo zokufaka izicelo ziya ngokuya ziba banzi, ikhwalithi yezintambo ezingashi kanye nezidingo zekhebula nazo ziya ngokuya ziba phezulu.
Intambo engashi kanye nekhebula isho intambo nekhebuli enekhono lokusebenza ngokuqhubekayo esimweni esishiwo lapho ivutha ngaphansi kwelangabi elishiwo nesikhathi, okungukuthi amandla okugcina ubuqotho bomugqa. Intambo engashi kanye nekhebula ngokuvamile kuba phakathi kwe-conductor kanye nongqimba olufakwa ngaphakathi kanye nongqimba lwe-refractory, ungqimba oluphikisayo luvamise ukuba yi-multi-layer refractory mica tape esongwe ngokuqondile ku-conductor. Ingacwiliswa kumshini wokuvikela oqinile, ominyene oxhunywe ebusweni bomqhubi lapho uvezwe emlilweni, futhi ungaqinisekisa ukusebenza okuvamile komugqa ngisho noma i-polymer elangabini elisetshenzisiwe ishiswa. Ngakho-ke ukukhetha kwe-mica tape ukumelana nomlilo kudlala indima ebalulekile kwikhwalithi yezintambo nezintambo ezingashi.
1 Ukwakhiwa kwamathephu e-mica aphikisayo nezici zokwakheka ngakunye
Kutheyiphu ye-mica ephikisayo, iphepha le-mica liwumthombo wangempela kagesi kanye nezinto eziphikisayo, kodwa iphepha le-mica ngokwalo alinawo amandla futhi kufanele liqiniswe ngezinto eziqinisayo ukuze lithuthukiswe, nokwenza iphepha le-mica nezinto eziqinisayo zibe into esemqoka. sebenzisa ingcina. Ngakho-ke impahla eluhlaza ye-refractory mica tape yenziwe ngephepha le-mica, izinto eziqinisayo (indwangu yengilazi noma ifilimu) kanye ne-resin adhesive.
1. 1 Mica iphepha
Iphepha le-Mica lihlukaniswe ngezinhlobo ezintathu ngokuya ngezakhiwo zamaminerali e-mica asetshenzisiwe.
( 1) Iphepha le-Mica elenziwe nge-white mica;
( 2) Iphepha le-Mica elenziwe ngegolide;
(3) Iphepha le-Mica elenziwe nge-synthetic mica njengempahla eluhlaza.
Lezi zinhlobo ezintathu zephepha le-mica zonke zinezici zazo zemvelo
Ezinhlotsheni ezintathu zephepha le-mica, izinga lokushisa likagesi legumbi lephepha le-mica lingcono kakhulu, i-synthetic mica paper ingeyesibili, iphepha le-mica legolide alilungile. Izakhiwo zikagesi emazingeni okushisa aphezulu, i-synthetic mica paper iyona ehamba phambili, i-mica paper yegolide ingeyesibili ehamba phambili, i-white mica paper impofu. I-synthetic mica ayinawo amanzi e-crystalline futhi inephuzu lokuncibilika lika-1,370 ° C, ngakho inokumelana okungcono kakhulu nokushisa okuphezulu; i-mica yegolide iqala ukukhulula amanzi e-crystalline ku-800 ° C futhi inokumelana kwesibili okuhle kakhulu nokushisa okuphezulu; i-white mica ikhipha amanzi ayi-crystalline ku-600 ° C futhi inokumelana okubi nokushisa okuphezulu. I-mica yegolide kanye ne-synthetic mica ngokuvamile isetshenziselwa ukukhiqiza amateyipu e-mica aphikisayo anezakhiwo ezingcono zokuphikisa.
1. 2 Izinto zokuqinisa
Izinto zokuqinisa ngokuvamile ziyindwangu yengilazi nefilimu yepulasitiki. Indwangu yengilazi iyi-filament eqhubekayo ye-glass fiber eyenziwe ngengilazi engena-alkali, okufanele ilukwe. Ifilimu ingasebenzisa izinhlobo ezahlukene zefilimu yepulasitiki, ukusetshenziswa kwefilimu yepulasitiki kunganciphisa izindleko futhi kuthuthukise ukumelana nokuhuzuka kwendawo, kodwa imikhiqizo ekhiqizwa ngesikhathi sokusha akufanele ichithe ukufakwa kwephepha le-mica, futhi kufanele ibe namandla anele, okwamanje. okuvame ukusetshenziswa ifilimu ye-polyester, ifilimu ye-polyethylene, njll. Kuhle ukusho ukuthi amandla aqinile we-mica tape ahlobene nohlobo lwezinto zokuqinisa, futhi ukusebenza okuqinile kwe-mica tape ene-glass cloth reinforcement ngokuvamile kuphakeme kunaleyo ye-mica tape. ngokuqiniswa kwefilimu. Ukwengeza, nakuba amandla e-IDF amateyipu e-mica ekamelweni lokushisa ahlobene nohlobo lwephepha le-mica, futhi lihlobene eduze nezinto eziqinisayo, futhi ngokuvamile amandla e-IDF amateyipu e-mica anokuqinisa ifilimu ekamelweni lokushisa aphakeme kunalokho. yamakhasethi we-mica ngaphandle kokuqiniswa kwefilimu.
1. 3 Izinamathiselo ze-resin
I-adhesive resin ihlanganisa iphepha le-mica kanye nezinto zokuqinisa zibe yinto eyodwa. I-adhesive kumele ikhethwe ukuze ihlangabezane namandla esibopho esiphezulu sephepha le-mica kanye nezinto zokuqinisa, i-mica tape inokuguquguquka okuthile futhi ayishisi ngemva kokuvutha. Kubalulekile ukuthi i-mica tape ingashi ngemva kokuvutha, njengoba ithinta ngokuqondile ukumelana nokufakwa kwe-mica tape ngemva kokuvutha. Njengento enamathelayo, lapho ibopha iphepha le-mica nezinto eziqinisayo, ingena kuma-pores kanye nama-micropores akho kokubili, iba ngumgudu wokuhambisa ugesi uma ivutha futhi i-char. Njengamanje, okunamathelayo okuvame ukusetshenziswa kwe-refractory mica tape iyingcina ye-silicone resin, ekhiqiza impushana emhlophe ye-silica ngemva kokusha futhi inezindawo ezinhle zokuvala ugesi.
Isiphetho
( 1) Amateyipu e-refractory mica ngokuvamile akhiqizwa kusetshenziswa i-golden mica kanye ne-synthetic mica, enezakhiwo ezingcono zikagesi emazingeni okushisa aphezulu.
( 2) Amandla aqinile wamateyipu e-mica ahlobene nohlobo lwezinto eziqinisayo, futhi izici eziqinile zamateyipu e-mica anezigxivizo zendwangu yengilazi ngokuvamile ziphakeme kunalawo amateyipu e-mica ane-reinforcement yefilimu.
( 3) Amandla e-IDF amateyipu e-mica ekushiseni kwegumbi ahlobene nohlobo lwephepha le-mica, kodwa futhi nezinto zokuqinisa, futhi ngokuvamile aphakeme kumateyipu e-mica anokuqinisa ifilimu kunalawo angenayo.
( 4) Izinamathiselo zamatheyiphu e-mica angashi zivame ukunamathela nge-silicone.
