Koj puas paub cov yam ntxwv thiab kev siv ntawm cov nplaim retardant casing?
1. Kev nyab xeeb thiab kev tiv thaiv ib puag ncig, tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm
Cov iav fiber ntau tsis muaj alkali nws tus kheej muaj cov yam ntxwv ntawm lub zog tensile, tsis muaj wrinkle thiab puas, vulcanization tsis kam, tsis muaj pa taws, tsis muaj halogen, tsis muaj tshuaj lom, ntshiab oxygen, tsis muaj hluav taws xob, thiab zoo rwb thaiv tsev. Cov neeg ua haujlwm noj qab haus huv thiab qhov xwm txheej ntawm kev ua haujlwm raug txo qis. Tsis zoo li cov khoom lag luam asbestos, nws muaj kev phom sij heev rau tib neeg lub cev thiab ib puag ncig.
2. Zoo heev kub ua hauj
Cov qauv silicone rau ntawm qhov chaw ntawm lub qhov hluav taws kub muaj ob qho tib si "organic pawg" thiab "cov qauv inorganic". Qhov tshwj xeeb muaj pes tsawg leeg thiab cov qauv molecular no ua rau nws sib xyaw cov yam ntxwv ntawm cov teeb meem organic thiab kev ua haujlwm ntawm cov teeb meem inorganic. Piv nrog rau lwm cov ntaub ntawv polymer, nws qhov tseem ceeb tshaj plaws yog nws qhov kub thiab txias. Nrog silicon-oxygen (Si-O) daim ntawv cog lus raws li cov qauv tseem ceeb, daim ntawv cog lus lub zog ntawm CC daim ntawv cog lus yog 82.6 kcal / mol, thiab lub zog ntawm Si-O daim ntawv cog lus yog 121 kcal / mol hauv silicone, yog li nws thermal stability yog siab, thiab cov tshuaj bonds ntawm molecules tsis tawg los yog decomposed nyob rau hauv siab kub (los yog hluav taws xob irradiation). Silicone tsis yog tsuas yog tiv taus qhov kub thiab txias, tab sis kuj tsis tshua muaj kub, thiab tuaj yeem siv rau ntau qhov kub thiab txias. Txawm hais tias nws yog cov khoom siv tshuaj lom neeg lossis lub cev thiab cov khoom siv kho tshuab, qhov kev hloov pauv nrog qhov kub thiab txias yog qhov tsawg heev.
3. Anti-splash, ntau yam kev tiv thaiv
Hauv kev lag luam smelting, qhov kub ntawm qhov nruab nrab hauv lub tshuab hluav taws xob cua sov yog qhov siab heev, uas yog ib qho yooj yim rau kev kub hnyiab (tib yam muaj tseeb hauv kev lag luam hluav taws xob vuam). Tom qab txias thiab solidification, slag yog tsim nyob rau hauv lub pipeline los yog cable, uas yuav harden cov roj hmab nyob rau hauv txheej txheej ntawm lub raj xa dej los yog cable, thiab nws thiaj li nkig tawg. Thiab tom qab ntawd ua rau cov khoom siv tsis muaj kev tiv thaiv thiab cables. Tom qab ntau txheej ntawm silicone-coated hluav taws-resistant casings, ntau yam kev tiv thaiv kev nyab xeeb tuaj yeem ua tiav. Qhov siab tshaj plaws kub kuj tuaj yeem siab txog 1300 degrees Celsius, uas tuaj yeem thaiv cov hlau molten, molten tooj liab, molten aluminium thiab lwm yam kub kub melts. txaws los tiv thaiv kev puas tsuaj rau ib puag ncig cables thiab khoom siv.
4. thermal rwb thaiv tsev, txuag hluav taws xob thiab txo kev noj, hluav taws xob tiv thaiv
Hauv chav ua haujlwm kub kub, ntau cov kav dej, li qub lossis cov khoom siv muaj qhov kub thiab txias sab hauv. Yog tias lawv tsis npog nrog cov khoom siv tiv thaiv, nws yooj yim ua rau kub hnyiab lossis kub poob. Fireproof casing muaj thermal stability zoo dua, hluav taws xob tiv thaiv thiab thermal rwb thaiv tsev dua li lwm cov ntaub ntawv polymer, tiv thaiv kev sib tsoo, txo kev siv hluav taws xob, thiab tiv thaiv cov cua sov ntawm nruab nrab hauv cov kav dej los ntawm kev xa ncaj qha mus rau ib puag ncig ib puag ncig thiab ua rau lub rhiav kev puas tsuaj. Qhov kub thiab txias heev, txuag cov nqi cua txias.
5. Moisture-pov thawj, roj-pov thawj, huab cua-pov thawj, muaj kuab paug-pov thawj, thiab ua kom lub neej ntev ntawm cov khoom siv.
Lub fireproof casing muaj zog tshuaj stability. Cov silicone tsis hnov mob rau roj, dej, kua qaub thiab alkali thiab lwm yam khoom. Nws tuaj yeem siv tau ntev yam tsis muaj kev laus li ntawm 260 degree. Kev pabcuam lub neej hauv ib puag ncig ntuj tuaj yeem ncav cuag ntau xyoo lawm. Txhawm rau txhim kho kev tiv thaiv cov kav dej, cables thiab cov khoom siv hauv cov sijhawm no, ua kom lawv lub neej ua haujlwm ntev.
6. Ozone kuj, voltage kuj, arc kuj, corona kuj ua tau zoo
Vim tias qhov saum npoo yog coated nrog cov organic silica gel, nws cov saw tseem ceeb yog -Si-O-, thiab tsis muaj ob daim ntawv cog lus, yog li nws tsis yooj yim rau decomposed los ntawm ultraviolet lub teeb thiab ozone. Cov hluav taws kub hnyiab muaj cov khoom siv hluav taws xob zoo, nws cov dielectric poob, tiv taus hluav taws xob, arc tsis kam, corona kuj, ntim resistivity thiab deg resistivity yog qhov zoo tshaj plaws hauv cov ntaub ntawv insulating, thiab lawv cov khoom hluav taws xob cuam tshuam los ntawm qhov kub thiab txias. Qhov cuam tshuam me me. Yog li ntawd, lawv yog cov khoom siv hluav taws xob ruaj khov thiab tau siv dav hauv kev lag luam hluav taws xob thiab hluav taws xob.
7. Cov nplaim hluav taws kub hnyiab, txo qhov tshwm sim thiab kis hluav taws
Yog hais tias lub nruab nrab flammable los yog tshuaj lom nruab nrab yog thauj nyob rau hauv lub pipeline, nws yog ib qho yooj yim ua rau hluav taws kub los yog casualties nyob rau hauv cov kev tshwm sim ntawm to; cable yog feem ntau hlawv vim qhov kub hauv zos; Muaj cov khoom siv tshwj xeeb xws li cov nplaim hluav taws xob tsim nyog, uas ua rau nws muaj cov nplaim hluav taws zoo heev. Txawm hais tias muaj hluav taws kub hnyiab, nws tuaj yeem tiv thaiv kev sib kis ntawm hluav taws, thiab tseem tiv thaiv cov kav dej hauv tsev kom tsis txhob muaj kev puas tsuaj rau lub sijhawm ntev, muab sijhawm txaus thiab txaus rau kev cawm cov ntaub ntawv tseem ceeb xws li cov ntaub ntawv thiab cov ntaub ntawv.
8. Yooj yim rau nruab thiab siv
Tsis tas yuav tsum tso tseg cov khoom siv lossis tshem tawm cov hoses thiab cables thaum txhim kho lub tes tsho tiv thaiv hluav taws kub. Lwm qhov zoo dua yog tias nws tuaj yeem ntsia tau rau ntawm qhov chaw ntawm lub Hoobkas kom ntseeg tau tias tsim nyog thiab muaj kev ncaj ncees.
