Shenhai Explosion-Ubungqina
Kwizicelo zombane ezingaqhushumba, izixhobo zokugquma zahlulwe zibe ziindidi eziqinileyo nezilulwelo, elungiselelwe ngokukodwa ezi zicelo, ngokungafaniyo neendidi ezibanzi zokugquma.
Izinto zokugquma eziSolid
Kubhekiselwa kuyo njenge “izinto zokugquma eziqinileyo,” ezi zizinto ezihlala ziqinile phantsi kweemeko zokusebenza. Olu didi lubandakanya izinto ezifana ne-insulating varnish, ezilulwelo ekuqaleni kodwa ziqina xa zifakwa.
Izinto ezixhaphakileyo zokugquma okuqinileyo kwizixhobo zombane ezingagqabhukiyo zidweliswe ngezantsi.
| Ibakala lezinto eziphathekayo | Xa kuthelekiswa ne-Tracking Index (CTI) | Igama lesixhobo |
|---|---|---|
| I | 600≤CTI | IiCeramics (imenyeziwe), mica, iglasi |
| II | 400≤CTI＜600 | Melamine asbestos arc iplastiki, abicah organic asbestos arc iplastiki ukumelana, unsaturated polyester aggregate |
| III-a | 175≤CTI＜400 | Polytetrafluoroethylene iplastiki, melamine glass fiber iplastiki, ibhodi yelaphu yeglasi ye-epoxy ephathwa ngepeyinti exhathisa i-arc kumphezulu |
| III-b | 100≤CTI＜175 | Iplastiki yePhenolic |
Ezi zixhobo zihlelwe ngokusekelwe kwi-Comparative Tracking Index (CTI), umlinganiselo wokusebenza kombane ongaphezulu. Nangona kunjalo, oomatshini babo, thermal, kunye neempawu zeekhemikhali zinokuhluka kakhulu, ifuna ukukhetha ngononophelo okusekwe kwiimeko ezithile zokusingqongileyo zokusetyenziswa, kuquka nokuqwalaselwa amandla oomatshini, ukumelana nobushushu, kunye nokuqina kweekhemikhali.
I-Ceramic (Ikhazimlisiwe) Izinto eziphathekayo
Iquka izinto zokugquma ezingezizo ezesinyithi, ezi zenziwe nge-sintering metal oxides kunye ne-non-oxygen metal compounds. Iimpawu zabo ziquka ubunzima be-1000 ~ 5000HV, amandla okuqina ukusuka kwi-26 ~ 36 MPa, amandla oxinzelelo ukusuka kwi-460 ~ 680 MPa, iindawo zokunyibilika ezingaphezu kwama-2000°C, ukwanda kwe-thermal ephantsi, kunye nokuzinza okuphezulu kweekhemikhali kunye nokuchasana nokubola.
Polytetrafluoroethylene (PTFE)
Esi sixhobo se-fluoroplastic sigcina ukusetyenziswa kwexesha elide kuwo wonke amaqondo obushushu ukusuka -180°C ukuya kuma-260°C.. Izinzile kakhulu kwiikhemikhali, ukumelana nomhlwa, ibonisa i-coefficient ephantsi yokhuhlane, kwaye ine-coefficient yokwandisa i-thermal ebalulekileyo.
Iplastiki yePhenolic
Iplastiki ye-thermosetting, eyaziwa ngokorhwebo njenge “bakelite” okanye “ibhodi phenolic,” inokumelana namaqondo obushushu angaphezu kwe-3000 ° C kwaye inika ukuxhathisa okugqwesileyo kokutshisa kunye nokuzinza kweekhemikhali, nangona i-brittle kwaye ayixhathisi kwi-alkali corrosion.
Ukongeza kwizinto eziqinileyo zokugquma ezikhankanywe, Isixhobo sombane esingenakugqabhuka sisebenzisa kakhulu izinto ezahlukeneyo zokugquma eziqinileyo, kubandakanywa izinto zeplastiki zamacandelo okugquma kunye nezixhobo ezithile ezincedisayo kwiinjini ezinobungqina bokuqhuma.
Izinto zokugquma ulwelo
Ezi zibhekisa kwizinto ezigqumayo ezifumaneka kulwelo, njengeoli ye-transformer, kunye nemathiriyeli efana nevanishi yokugquma esetyenziselwa ukumilisela ikhoyili, ezithi ziqina emva konyango oluthile ukanti zisajongwa njengezigqumatheli zolwelo.
1. Ioyile yoTshintsho
• Kubalulekile kwizixhobo zombane ezingaqhubi njengee-transformer, le oli kufuneka ihlangabezane nemigangatho ethile:
• Indawo yokutshisa ingabi ngaphantsi kwama-300°C.
• Indawo yokudanyaza ingabi ngaphantsi kwama-200°C (ikomityi evaliweyo).
• I-Kinematic viscosity engagqithiyo 1*10?? m²/s kwi-25°C.
• Amandla okuqhawuka kweDielectric ubuncinane ngama-27kV.
• Ukuxhathisa umthamo ubuncinane 1*10??? m kwi-25°C.
• Iqondo lokugalela lingabi ngaphezu kwe -30°C.
• Ubumuncu (ixabiso le-neutralization) ixhomekeke ku 0.03 mg/g (i-potassium hydroxide).
Ioli yokuguqula, ngokuyintloko i-oyile yokukhusela iminerali equka i-alkanes, iicycloalkanes, kunye neehydrocarbons ezinevumba elimnandi, inikeza iimpawu ezigqwesileyo zokugquma kunye nozinzo lokuguga. Nangona kunjalo, usetyenziso lwayo kwizixhobo zemigodi zeKlasi yoku-I luthintelwe ngenxa yokuthotywa okunokwenzeka kwezakhiwo zayo zokugquma phezu kokusetyenziswa ixesha elide..
2. Ivanishi
Isetyenziselwa ukufaka iikhoyili zombane kwisixhobo sokuthintela uqhushumbo, ukugquma ivanishi kuphucula amandla abo okugquma umbane. Ifumaneka kwiifom ezisekelwe kwi-solvent kunye ne-solvent-free, ezi vanishi zenziwe ngeereyini zendalo okanye ezenziweyo ezidityaniswe nezinyibilikisi ezahlukeneyo ezifana nebenzene kunye nealcohols kuhlobo olusekwe kwi-solvent., kunye neerasi zokwenziwa, ii-agent zokuqinisa, kunye ne-thinners esebenzayo njenge-styrene yodidi lwe-solvent-free.
Zombini iintlobo zevanishi zibonelela ngeendlela ezininzi zokuhlangabezana neemfuno ezahlukeneyo zesicelo, ukuqinisekisa ukuziqhelanisa neemfuneko ezithile zokusebenza.
