Hloov hauv Chemical Reaction Rate

Qhov kub thiab txias yog qhov tseem ceeb cuam tshuam rau tus nqi ntawm cov tshuaj tiv thaiv. Rau cov tshuaj chemical hauv kua nplaum-raws li tsis siv neeg tua hluav taws cov ntaub ntawv, qhov nce hauv qhov kub yuav ua kom nrawm nrawm ntawm cov molecules, nce kev sib tsoo ntau zaus thiab lub zog ntawm cov molecules, thiab yog li ua kom cov tshuaj lom neeg muaj zog nce ntxiv. Piv txwv li, qee cov khoom siv hauv cov khoom yuav raug thermal decomposition tshwm sim, thiab tus nqi decomposition yuav nce ntawm qhov kub thiab txias, uas ua rau txo qis cov khoom siv hluav taws xob tua hluav taws thiab txo cov hluav taws tua hluav taws ntawm cov khoom siv. Piv txwv li, qee cov nplaim hluav taws kub hnyiab uas muaj nitrogen thiab phosphorus tuaj yeem decompose ua ntej ntawm qhov kub thiab txias thiab tsis tuaj yeem tiv thaiv kev sib tsoo thaum hluav taws tshwm sim.

Hloov hauv Cov Khoom Siv Lub Cev

1. Hloov viscosity: Kub hloov pauv yuav cuam tshuam qhov viscosity ntawm cov kua nplaum. Feem ntau hais lus, thaum qhov kub thiab txias nce, lub zog intermolecular tsis muaj zog, thiab viscosity ntawm cov kua nplaum yuav txo qis, ua rau nws muaj kua ntau dua; Thaum qhov kub thiab txias, qhov kev ua ntawm molecular tsis muaj zog, viscosity nce, thiab nws tuaj yeem ua kom khov lossis crystallize. Rau cov khoom siv hluav taws kub tsis siv neeg, qhov tsim nyog viscosity yog qhov tseem ceeb rau lawv txoj kev thauj mus los thiab kev faib tawm hauv cov khoom tua hluav taws. Yog tias qhov hloov pauv viscosity ntau dhau qhov tsim nyog, nws yuav ua rau cov khoom tsis tuaj yeem txau ib txwm los yog thaiv hauv cov kav dej, cuam tshuam rau kev tua hluav taws. Piv txwv li, nyob rau hauv qhov chaw kub kub, qhov viscosity ntawm cov kua nplaum yuav txo qis, uas tuaj yeem ua rau cov dej xau hauv lub thawv ntim khoom; Thaum qhov kub thiab txias qis, qhov viscosity nce, ua rau nws nyuaj rau tshuaj tsuag los ntawm lub nozzle.
2. Thermal Expansion thiab Contraction: Cov khoom yuav nthuav dav thaum cua sov thiab cog lus thaum txias. Qhov tshwm sim ntawm thermal expansion thiab contraction tuaj yeem ua rau muaj kev hloov pauv hauv cov qauv ntawm cov khoom siv thiab tsim kev ntxhov siab. Thaum cov khoom nyob rau hauv ib puag ncig kub-hloov mus ntev, cov teeb meem xws li tawg thiab delamination tuaj yeem tshwm sim, ua rau nws txoj kev ncaj ncees thiab ruaj khov, thiab cuam tshuam ntxiv rau nws qhov kev tua hluav taws. Piv txwv li, hauv qee qhov kev tua hluav taws sab nraum zoov, qhov kub thiab txias sib txawv ntawm nruab hnub thiab hmo ntuj ua rau cov khoom siv rov qab thermal expansion thiab contraction, uas yuav ua rau muaj kev puas tsuaj.

Acceleration ntawm Txoj Kev Laus

Qhov kub thiab txias yuav ua rau kom cov khoom qub, ua rau nws cov kev ua haujlwm poob sai dua lub sijhawm. Thaum lub sij hawm kev laus, cov saw molecular yuav raug hloov pauv xws li kev tawg thiab kev sib txuas, hloov cov qauv tshuaj thiab lub cev ntawm cov khoom. Piv txwv li, nyob rau hauv high-molecular polymer-raws li cov nplaum nplaum, cov saw molecular tawg ntawm qhov kub thiab txias, thiab qhov hnyav molecular txo, ua rau txo qis zog, yooj thiab lwm yam khoom ntawm cov khoom, txo qhov kev cia siab thiab kev pab cuam lub neej ntawm kev tua hluav taws.

 

Influence Mechanism of Humidity on the Stability of Glue-based Automatic Fire Suppression Materials

Moisture adsorption thiab tshuaj tiv thaiv

1. Hydrolysis Reaction: Ntau yam tshuaj nyob rau hauv cov kua nplaum uas tsis siv neeg tua hluav taws cov ntaub ntawv yuav ua rau muaj kev cuam tshuam hydrolysis nrog cov dej noo. Piv txwv li, qee cov organic ester Cheebtsam yuav hydrolyze nyob rau hauv qhov kev txiav txim ntawm dej los tsim cov kua qaub thiab cawv, hloov cov tshuaj muaj pes tsawg leeg thiab cov khoom ntawm cov khoom. Cov tshuaj tiv thaiv hydrolysis kuj tseem tuaj yeem tsim cov tshuaj acidic, uas yuav ua rau cov hlau tsis zoo ntawm cov cuab yeej tua hluav taws thiab cuam tshuam rau kev ua haujlwm ntawm cov khoom siv.
2. Kev Tshaj Tawm ntawm Lwm Cov Tshuaj Tiv Thaiv: Lub xub ntiag ntawm cov dej noo tuaj yeem ua rau muaj kev cuam tshuam rau lwm yam tshuaj lom neeg thiab ua kom cov khoom tsis zoo. Piv txwv li, nyob rau hauv ib puag ncig high-humidity, qee cov hlau ntsev catalysts yuav yaj hauv dej, ua rau muaj kev cuam tshuam tsis tsim nyog ntawm lwm cov khoom hauv cov khoom thiab txo cov hluav taws tua hluav taws.

Hloov hauv Cov Khoom Siv Lub Cev

1. Expansion Ua los ntawm Moisture Absorption: Cov khoom siv tuaj yeem nthuav dav tom qab nqus dej noo, hloov nws lub ntim thiab ntom. Qhov no yuav tsis tsuas yog cuam tshuam rau kev sau thiab kev faib khoom ntawm cov khoom siv hluav taws xob tua hluav taws tab sis kuj tseem ua rau lub zog ntawm cov qauv ntawm cov cuab yeej, uas ua rau muaj teeb meem xws li kev puas tsuaj rau cov ntsaws ruaj ruaj thiab deformation ntawm cov kav dej. Piv txwv li, qee cov khoom siv tua hluav taws uas muaj cov dej nqus dej tuaj yeem nthuav dav hauv cov ntim tom qab nqus dej noo, uas tuaj yeem tawg lub thawv ntim khoom.

Tom qab cov molecular absorbs lub zog photon, cov saw hlau molecular tawg, ua rau txo qis hauv molecular hnyav thiab kev ua haujlwm tsis zoo. Piv txwv li, cov polymers uas muaj cov ntawv cog lus tsis txaus ntseeg yog qhov ua rau tawg ntawm cov ntawv cog lus tsis txaus ntseeg nyob rau hauv cov hluav taws xob ultraviolet, ua rau cov khoom poob nws qhov qub zog thiab yooj thiab cuam tshuam rau nws cov hluav taws tua hluav taws.
2. Photooxidation: Lub teeb yuav ceev cov txheej txheem oxidation ntawm cov khoom, uas yog, cov tshuaj tiv thaiv photooxidation. Thaum muaj cov pa oxygen, cov molecules hauv cov khoom cuam tshuam nrog photons los tsim cov dawb radicals, thiab cov dawb radicals hnov ​​​​mob nrog oxygen los tsim cov khoom oxidation xws li peroxides, ntxiv rau kev tawg thiab kev sib txuas ntawm cov saw molecular thiab ua rau kev laus thiab kev ua haujlwm ntawm cov khoom. Piv txwv li, rau qee cov ntaub ntawv uas muaj cov tshuaj antioxidants, kev noj cov tshuaj antioxidants tau nrawm dua hauv lub teeb, thiab lawv tsis tuaj yeem cuam tshuam cov tshuaj tiv thaiv oxidation, ua rau cov khoom muaj hnub nyoog sai.

Hloov xim thiab pob tshab

Lub teeb yuav ua rau muaj kev hloov xim thiab pob tshab ntawm cov khoom. Kev hloov xim tuaj yeem cuam tshuam rau kev txiav txim siab ntawm cov khoom siv hauv lub xeev, thiab qhov txo qis ntawm qhov pom tseeb tuaj yeem cuam tshuam rau kev soj ntsuam ntawm qhov xwm txheej sab hauv ntawm cov khoom tua hluav taws. Ntxiv mus, cov kev hloov pauv ntawm cov khoom siv kho qhov muag feem ntau nrog cov kev hloov hauv cov qauv tshuaj thiab lub cev ntawm cov khoom. Piv txwv li, kev tsaus ntuj ntawm cov xim yuav txhais tau tias cov khoom tau dhau los ua carbonization lossis oxidation, uas yuav txo tau qhov ruaj khov thiab tua hluav taws ntawm cov khoom siv.

 

Synergistic Influence ntawm Comprehensive Environmental Factors

Hauv kev siv tswv yim, ib puag ncig yam xws li kub, av noo, thiab lub teeb feem ntau tsis ua ib leeg tab sis cuam tshuam nrog ib leeg thiab ua kom muaj zog ntawm cov kua nplaum uas siv hluav taws xob tua hluav taws. Piv txwv li, thaum kub kub thiab av noo nyob ib txhij, cov tshuaj tiv thaiv hydrolysis thiab thermal decomposition cov tshuaj tiv thaiv yuav txhawb ib leeg, accelerating lub deterioration ntawm cov khoom ua hauj lwm; Kev sib xyaw ua ke ntawm lub teeb thiab kub siab yuav ua rau cov tshuaj tiv thaiv photochemical thiab thermal aging, ua rau cov khoom muaj hnub nyoog sai. Yog li ntawd, thaum kawm txog kev ruaj ntseg ntawm cov khoom siv thiab txiav txim siab qhov chaw cia khoom, yuav tsum xav txog qhov kev cuam tshuam ntawm ntau yam ib puag ncig.

 

Cov xwm txheej cia rau txuas ntxiv lub neej kev pab cuam ntawm cov kua nplaum-raws li cov khoom siv hluav taws xob tua hluav taws

kub Control

1. Cia Khoom Kub Ntau Yam: Txiav txim siab qhov ntsuas kub kom tsim nyog raws li cov yam ntxwv ntawm cov khoom siv. Feem ntau hais lus, feem ntau cov kua nplaum uas tsis siv neeg tua hluav taws yog tsim rau khaws cia hauv ib puag ncig nrog qhov kub ntawm 5 ° C - 25 ° C. Nyob rau hauv qhov kub thiab txias no, cov tshuaj tiv thaiv tus nqi tuaj yeem ua rau qeeb qeeb, qhov cuam tshuam ntawm thermal expansion thiab contraction thiab aging yuav txo tau, thiab lub cev thiab tshuaj lub zog ntawm cov khoom yuav ruaj khov.
2. Zam kev hloov pauv kub: Sim txo qhov kub ntawm qhov hloov pauv hauv qhov chaw cia khoom thiab siv cov khoom siv hluav taws xob thiab cov khoom siv kub tsis tu ncua, xws li qhov kub thiab txias warehouses thiab insulated thawv.
