Intshayelelo
Kwizikhululo zeenqwelomoya, izibhedlele, amaziko okuthenga, i-subways, izakhiwo eziphakamileyo kunye nezinye iindawo ezibalulekileyo, ukwenzela ukuba kuqinisekiswe ukhuseleko lwabantu xa kukho umlilo kunye nokusebenza okuqhelekileyo kweenkqubo zongxamiseko, kuyimfuneko ukusebenzisa ucingo olungenakunqanda umlilo. kunye nentambo enokumelana nomlilo okugqwesileyo. Ngenxa yokonyuka kwengqalelo kukhuseleko lomntu, imfuno yentengiso yeentambo ezikwaziyo ukumelana nomlilo nayo iyanda, kwaye neendawo zokufaka izicelo ziya zisanda ngakumbi nangakumbi, umgangatho wocingo olukwaziyo ukumelana nomlilo kunye neemfuno zeentambo nazo ziya ziphakama.
I-wire-resistant wire kunye nentambo ibhekisela kwintambo kunye nekhebula elinamandla okusebenza ngokuqhubekayo kwimeko ethile xa uvutha phantsi komlilo ochaziweyo kunye nexesha, oko kukuthi ukukwazi ukugcina ingqibelelo yomgca. Ucingo olukwaziyo ukumelana nomlilo kunye nentambo idla ngokuba phakathi kwe-conductor kunye ne-insulation layer kunye nomaleko we-refractory layer, i-refractory layer idla ngokuba yi-multi-layer refractory mica tape esongelwe ngqo kwi-conductor. Inokuthi ifakwe kwi-insulator enzima, i-dense insulator ifakwe kumphezulu womqhubi xa ibonakaliswe emlilweni, kwaye inokuqinisekisa ukusebenza okuqhelekileyo komgca nokuba i-polymer kwilangatye elisetyenzisiweyo litshiswa. Ukukhetha i-mica tape enganyangekiyo ke ngoko idlala indima ebalulekileyo kumgangatho weengcingo ezikwaziyo ukumelana nomlilo kunye neentambo.
1 Ukuqulunqwa kweetape ze-mica ezichasayo kunye neempawu zokwakheka ngalunye
Kwitape ye-refractory mica, iphepha le-mica yeyona nto yokwenyani yokufakelwa kombane kunye nezinto ezichasayo, kodwa iphepha le-mica ngokwalo phantse alinamandla kwaye kufuneka liqiniswe ngezinto eziqinisayo ukuze ziphucule, kwaye ukwenza iphepha le-mica kunye nezinto zokuqinisa zibe yinto enye. sebenzisa i-adhesive. Izinto eziluhlaza ze-refractory mica tape ke ngoko zenziwe ngephepha le-mica, izinto zokuqinisa (indwangu yeglasi okanye ifilimu) kunye ne-resin adhesive.
1. Iphepha leMica eli-1
Iphepha leMica lihlulwe libe ziintlobo ezintathu ngokweempawu zemica minerals esetyenzisiweyo.
( 1) Iphepha leMica elenziwe kwimica emhlophe;
( 2) Iphepha leMica elenziwe ngegolide;
( 3) Iphepha leMica elenziwe nge-synthetic mica njengento ekrwada.
Ezi ntlobo zintathu zephepha le-mica zonke zineempawu zazo zendalo
Kwiintlobo ezintathu zephepha lemica, ubushushu begumbi iimpawu zombane zephepha lemica lelona lihle, iphepha lemica lokwenziwa lelesibini, iphepha lemica legolide lihlwempuzekile. Iimpawu zombane kumaqondo obushushu aphezulu, iphepha le-mica lokwenziwa lelona ligqwesileyo, iphepha le-mica legolide lesibini, iphepha lemica elimhlophe lihlwempuzekile. I-Synthetic mica ayinayo amanzi e-crystalline kwaye ine-melting point ye-1,370 ° C, ngoko inokumelana neyona ndlela yokushisa ephezulu; i-mica yegolide iqala ukukhulula amanzi e-crystalline kwi-800 ° C kwaye inesibini esichasayo kwiqondo lokushisa eliphezulu; i-mica emhlophe ikhupha amanzi e-crystalline kwi-600 ° C kwaye inokumelana kakubi kumaqondo aphezulu. I-Mica yegolide kunye ne-synthetic mica zidla ngokusetyenziselwa ukuvelisa i-refractory mica tapes kunye neempawu ezingcono zokuphikisa.
1. 2 Ukuqinisa imathiriyeli
Izinto zokuqinisa zihlala zilaphu leglasi kunye nefilimu yeplastiki. Ilaphu leglasi yifilament eqhubekayo yeglass fiber eyenziwe ngeglasi engena alkali, ekufuneka ilukwe. Ifilimu ingasebenzisa iintlobo ezahlukeneyo zefilimu yeplastiki, ukusetyenziswa kwefilimu yeplastiki kunokunciphisa iindleko kunye nokuphucula ukuxhathisa kwe-abrasion ebusweni, kodwa iimveliso eziveliswa ngexesha lokutsha akufanele zitshabalalise ukufakwa kwephepha le-mica, kwaye kufuneka zibe namandla okwaneleyo, okwangoku. ngokuqhelekileyo isetyenziselwa ifilimu ye-polyester, ifilimu ye-polyethylene, njl. Kuyafaneleka ukukhankanya ukuba amandla okuqina e-mica tape ahambelana nohlobo lwezinto zokuqinisa, kunye nokusebenza kwe-mica tape kunye nokuqiniswa kwelaphu yeglasi kuphezulu kakhulu kunoko kwe-mica tape. ngokuqiniswa kwefilimu. Ukongeza, nangona amandla e-IDF e-mica tapes kwiqondo lobushushu begumbi lihambelana nohlobo lwephepha le-mica, likwanxulumene ngokusondeleyo nezinto eziqiniswayo, kwaye ngokuqhelekileyo amandla e-IDF e-mica tapes kunye nokuqiniswa kwefilimu kwiqondo lokushisa eliphezulu kunoko. yeeteyiphu zemica ngaphandle kokuqiniswa kwefilimu.
1. 3 Izincamathelisi ze-resin
I-resin adhesive idibanisa iphepha le-mica kunye nezinto zokuqiniswa zibe yinye. I-adhesive kufuneka ikhethwe ukuhlangabezana nokuqina okuphezulu kwephepha le-mica kunye nezinto zokuqiniswa, i-tape ye-mica ine-flexibility ethile kwaye ayifuni emva kokutshisa. Kubalulekile ukuba i-mica tape ingatshisi emva kokutshisa, njengoko ichaphazela ngokuthe ngqo ukunyanzeliswa kwe-insulation ye-mica tape emva kokutshisa. Njengoko i-adhesive, xa udibanisa iphepha le-mica kunye nezinto zokuqinisa, zingena kwiipores kunye ne-micropores zombini, iba ngumjelo wokuqhuba umbane ukuba uyatshisa kunye ne-char. Okwangoku, i-adhesive esetyenziswa ngokuqhelekileyo kwi-refractory mica tape yi-adhesive ye-silicone ye-resin, evelisa umgubo omhlophe we-silica emva kokutsha kwaye ineempawu ezilungileyo zokugquma umbane.
Ukuqukumbela
( 1) Iiteyiphu ze-refractory mica zidla ngokuveliswa kusetyenziswa imica yegolide kunye ne-synthetic mica, eneempawu ezingcono zombane kumaqondo obushushu aphezulu.
(2) Amandla okuqina ee-mica tapes ahambelana nohlobo lwezinto eziqiniswayo, kunye neempawu zokuqina zemica tapes kunye nokuqinisa ngelaphu leglasi ngokuqhelekileyo ziphezulu kunezo zemica tapes kunye nokuqiniswa kwefilimu.
( 3 ) Amandla e-IDF eemica tapes kwiqondo lobushushu begumbi lihambelana nohlobo lwephepha lemica, kodwa nakwizinto eziqiniswayo, kwaye ngokuqhelekileyo ziphezulu kwimica tapes ngokuqiniswa kwefilimu kunabo bangenayo.
( 4 ) I-Adhesives ye-mica tapes ekwazi ukumelana nomlilo idla ngokuba yi-silicone.
