3. Alloys
Alloys ua si ib lub luag haujlwm tseem ceeb hauv kev ua kom tailoring cov hluav taws xob thiab cov yam ntxwv thermal ntawm cov fuse cov ntaub ntawv. Tin-txhuas thiab Nickel-chromium alloys feem ntau siv los kho lub suab nkauj melting taw tes thiab ua kom paub meej tias lub fuse ua haujlwm kom raug nyob rau hauv nws cov qauv tsis sib xws.
Tin-coj alloy fuses yog nthuav dav nyob rau hauv cov ntawv thov tsawg. Kev sib xyaw ua ke ntawm Tin thiab Lead muab cov ntsiab lus yaj yaj, tso cai rau kev tswj hwm tus cwj pwm fuse raws cov kev mob sib txawv raws li cov xwm txheej sib txawv.
Nickel-chromium alloys tau ua haujlwm hauv kev kub ntxhov siab vim lawv lub siab melting taw tes thiab kav ntev. Cov alloys kom paub tseeb tias cov fuse tuaj yeem tiv thaiv huab yuav tsis muaj kev txwv tsis pub dhau los yog ua tsis tiav.
Rooj 2: Ntau cov allo xijs siv nyob rau hauv fuse Hais
| Hlau | Melting taw tes ntau (degree) | Daim ntawv thov |
|---|---|---|
| Tin-txhuas | 183–215 | Tsawg heev voltage, electronics |
| Npib-Chromium | 1400–1500 | High temp, Kev Lag Luam |
4. Cov ntaub ntawv muaj feem xyuam
Cov ntaub ntawv ceramic tau siv ntau yam hauv kev tsim kho ntawm cov tsev fuse thiab vaj tse. Ceramics muab cov thermal hluav taws xob siab thiab cov hluav taws xob hluav taws xob siab, ua rau lawv zoo tagnrho rau kev tiv thaiv cov khoom siv fuse los ntawm kev ua haujlwm sab nraud thiab ua kom muaj kev nyab xeeb.
Ceramic fuse lub cev yog tsim kom muaj kev tiv thaiv kom muaj qhov kub siab rau lub sijhawm ua haujlwm fuse. Thaum lub tsev ntim fuse tiv thaiv kev tiv thaiv cov cua sov los ntawm kev cuam tshuam ib puag ncig ib puag ncig, txo kev pheej hmoo ntawm hluav taws lossis kev puas tsuaj.
5. Iav
Iav yog lwm yam khoom siv uas siv tau ua ke hauv fuse tsim, tshwj xeeb nyob rau hauv daim ntawv ntawm lub iav hlab. Iav muaj transparency, tso cai rau kev tshuaj xyuas lub fuse keeb, uas tau txais txiaj ntsig rau kev saib xyuas thiab daws teeb meem. Iav Kuj tseem muab cov khoom siv rasulies zoo thiab kav ntev.
6. Yas thiab Polymer Teb Chaws
Ntau yam plastics thiab polymer sib txuas yog siv hauv cov tshuab fuse, xws li Phenolic Resin thiab Polyester. Cov ntaub ntawv no tau xaiv rau lawv cov khoom siv hluav taws xob tsis muaj zog, thiab tiv thaiv kom sov, ua rau lawv haum rau cov txheej txheem fis.
