1. Kev nyab xeeb thiab kev tiv thaiv ib puag ncig los tiv thaiv kev noj qab haus huv ntawm cov neeg ua haujlwm.
Alkali-dawb iav fiber nws tus kheej muaj cov yam ntxwv ntawm lub zog tensile quab yuam, tsis muaj wrinkle thiab breakage, vulcanization kuj, tsis haus luam yeeb, halogen-dawb thiab nontoxic, ntshiab oxygen yog nonflammable, thiab zoo rwb thaiv tsev.Tom qab kho tau los ntawm cov organic silica gel, nws ntxiv dag zog rau nws txoj kev nyab xeeb thiab kev tiv thaiv ib puag ncig, tiv thaiv cov neeg ua haujlwm noj qab haus huv thiab txo cov xwm txheej ntawm kev ua haujlwm.Tsis zoo li cov khoom lag luam asbestos, nws muaj kev phom sij heev rau tib neeg lub cev thiab ib puag ncig.
2. Kev kub siab ua haujlwm zoo heev
Cov qauv silicone ntawm lub tes tsho tiv thaiv hluav taws muaj ob qho "organic group" thiab "inorganic structure".Qhov tshwj xeeb muaj pes tsawg leeg thiab cov qauv molecular no ua rau nws ua ke cov yam ntxwv ntawm cov teeb meem organic nrog kev ua haujlwm ntawm cov teeb meem inorganic.Piv nrog rau lwm cov ntaub ntawv polymer, nws qhov zoo 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 Si-O daim ntawv cog lus yog 121 kcal / mol hauv silicone, yog li nws muaj thermal stability, thiab cov tshuaj sib txuas ntawm cov molecules tsis tawg lossis decompose ntawm qhov kub thiab txias (los yog nyob rau hauv hluav taws xob irradiation).Silicone tsis tuaj yeem tiv taus qhov kub thiab txias, tab sis kuj tsis tshua muaj kub, thiab tuaj yeem siv rau hauv qhov kub thiab txias.Ob qho tshuaj lom neeg thiab lub cev thiab cov khoom siv kho tshuab hloov me ntsis nrog qhov kub thiab txias.
3. Kev tiv thaiv txaws thiab tiv thaiv ntau yam
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 ua kom kub-txias (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 embrittle thiab tawg.Tsis tas li ntawd, cov khoom siv tsis muaj kev tiv thaiv thiab cov cables raug puas tsuaj, thiab ntau yam kev tiv thaiv kev nyab xeeb tuaj yeem pom tau los ntawm ntau lub tes tsho tiv thaiv hluav taws uas muaj silica gel, thiab qhov kub siab tshaj plaws tuaj yeem ua rau siab txog 1,300 degrees Celsius, uas tuaj yeem tiv thaiv kev tawg ntawm qhov siab- kub melts xws li molten hlau, molten tooj liab thiab molten aluminium, thiab tiv thaiv cov cables nyob ib puag ncig thiab cov khoom siv los ntawm kev puas tsuaj.
4. thermal rwb thaiv tsev, txuag hluav taws xob, hluav taws xob tiv thaiv.
Nyob rau hauv qhov kub kub rhiav, qhov kub thiab txias ntawm ntau cov kav dej, li qub los yog cov khoom siv yog siab heev.Yog tias cov khoom tiv thaiv tsis yog coated, nws yog ib qho yooj yim uas yuav ua rau tus kheej kub hnyiab los yog kub poob.Lub tes tsho tiv thaiv hluav taws muaj kev ruaj ntseg zoo dua, hluav taws xob tiv thaiv thiab thermal rwb thaiv tsev dua li lwm cov ntaub ntawv polymer, uas tuaj yeem tiv thaiv kev sib tsoo thiab txo lub zog noj, thiab tseem tuaj yeem tiv thaiv qhov kub ntawm qhov nruab nrab hauv cov raj xa dej ncaj qha mus rau ib puag ncig, yog li ntawd. qhov kub ntawm lub rooj cob qhia yog siab dhau lawm thiab cov nqi txias tau txais kev cawmdim.
5. Moisture-pov thawj, roj-pov thawj, huab cua-laus-pov thawj thiab muaj kuab paug-pov thawj kom ntev lub neej kev pabcuam ntawm cov khoom siv.
Fireproof casing muaj cov tshuaj muaj zog ruaj khov, thiab nws tsis tuaj yeem ua rau cov roj, dej, kua qaub thiab alkali hauv silicone.Nws tuaj yeem siv tau ntev ntawm 260 ℃ yam tsis muaj kev laus, thiab nws lub neej kev pabcuam hauv ib puag ncig ntuj tuaj yeem ncav cuag ntau xyoo lawm, uas tuaj yeem tiv thaiv cov kav dej, cables thiab khoom siv hauv cov sijhawm no mus rau qhov siab tshaj plaws thiab ua kom nws lub neej ua haujlwm ntev.
6. Ozone kuj, voltage kuj, arc kuj thiab corona kuj.
Vim tias qhov saum npoo yog coated nrog cov organic silica gel, nws cov saw tseem ceeb yog-Si-O-, thiab tsis muaj daim ntawv cog lus, yog li nws tsis yooj yim rau decomposed los ntawm ultraviolet lub teeb thiab ozone.Lub tes tsho Fireproof muaj cov hluav taws xob rwb thaiv tsev zoo, thiab lawv cov dielectric poob, voltage tsis kam, arc kuj, corona kuj, ntim kuj coefficient thiab nto kuj coefficient yog qhov zoo tshaj plaws ntawm cov ntaub ntawv insulating, thiab lawv cov khoom hluav taws xob tsis tshua muaj kev cuam tshuam los ntawm qhov kub thiab txias.Yog li ntawd, lawv yog cov khoom siv hluav taws xob ruaj khov, uas tau siv dav hauv kev lag luam hluav taws xob thiab hluav taws xob.
7. Nplaim-retardant, txo cov hluav taws kub thiab kis ceev.
Yog tias cov nplaim hluav taws kub hnyiab tau raug thauj mus rau hauv cov raj xa dej, nws yooj yim ua rau hluav taws kub los yog raug mob thaum muaj hluav taws xob;Cables feem ntau hlawv vim qhov kub hauv zos;Lub tes tsho fireproof yog woven nrog kub-kub resistant iav fiber ntau, thiab silica gel nyob rau saum npoo yog ntxiv nrog tshwj xeeb raw cov ntaub ntawv xws li nplaim hluav taws retardant, uas ua rau nws muaj zoo heev nplaim retardancy.Txawm hais tias qhov hluav taws kub tawg, nws tuaj yeem tiv thaiv qhov hluav taws kub sib kis, thiab nws tseem tuaj yeem tiv thaiv cov kav dej sab hauv kom zoo rau lub sijhawm ntev, uas 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 installation thiab siv
Thaum txhim kho lub tes tsho thermal fireproof, nws tsis tas yuav tsum nres cov khoom siv thiab tshem tawm cov hose thiab cable.Lwm qhov zoo dua yog tias nws tuaj yeem ntsia tau rau ntawm qhov chaw hauv lub Hoobkas kom paub meej qhov tseeb haum thiab kev ua haujlwm zoo.
