Dab tsi yog vim li cas rau xeb ntawm PU steel hlau hose?
Cov qauv ntawm cov khoom siv PU steel yeeb nkab yog cov hlau hlau yog kos rau hauv phab ntsa sab hauv ntawm lub hose. Cov yeeb nkab ntawm qhov zoo yuav tsum tau muab tso rau hauv nruj kom tsis muaj qhov khoob, thiab yuav tsis muaj chaw rau huab cua thiab dej nkag. Yog hais tias cov hlau xaim ntawm PU steel yeeb nkab tsis kos txaus Nws yog nruj thiab muaj kev cuam tshuam zoo rau cov khoom zoo, vim tias qhov xwm txheej no cuam tshuam rau lub luag haujlwm lub neej ntawm PU steel hlau yeeb nkab. , yuav ua rau cov tsos ntawm xeb ntawm tooj liab-plated steel hlau. Yog tias qhov xwm txheej zoo li no tshwm sim, yog tias lub hose yuav tsum muaj qee qhov kev txav txav ntawm lub telescopic thaum siv, nws yuav ua rau muaj kev sib txhuam ntawm cov hose thiab cov yeeb nkab phab ntsa nce, uas yuav yooj yim ua rau cov tsos ntawm cov yeeb nkab phab ntsa. Kev puas tsuaj tsis tsim nyog tshwm sim, uas cuam tshuam rau lub neej kev pab cuam ntawm PU steel yeeb nkab.
Kev tshuaj xyuas thiab kev tiv thaiv txoj kev xeb thiab yellowing ntawm PU steel yeeb nkab
Kev tshuaj xyuas thiab kev tiv thaiv yellowing ntawm PU steel hlau yeeb nkab lub cev
1. Lub yellowing ntawm PU steel hlau hose tshwm sim los ntawm cov nyhuv antioxidant. Tam sim no ntau PU steel hlau hoses feem ntau xaiv TDI (toluene diisocyanate) los yog MDI (diphenylmethane diisocyanate) ua raw khoom. Cov tshuaj no tau txais cov tshuaj lom neeg tsis zoo nyob rau hauv kev ua ntawm lub teeb, cua sov, oxygen, thiab tshwj xeeb tshaj yog ultraviolet rays los tsim chromophores. Yog li ntawd, qhov tshwm sim ntawm PU steel hlau hose yog ib qho yooj yim rau daj thiab tsis tuaj yeem tuav cov xim pob tshab rau lub sijhawm ntev.
2. Cov nyhuv ntawm ultraviolet rays tseem yuav ua rau PU steel hlau hose tig daj. Thaum ua tiav PU steel hlau hose yog tsim thiab yuav tsum tau muab tso rau lub sijhawm. Yuav tsum muab tso rau hauv qhov chaw qhuav nrog lub teeb qis. Tshwj xeeb tshaj yog zam kev tshav ntuj ncaj qha.
Kev daws los tiv thaiv yellowing ntawm PU steel hlau hoses:
Txo cov pa oxygen hauv thaj chaw uas PU steel hlau hoses raug tsim thiab khaws cia (tuaj yeem ntim nrog cov roj inert). Nws kuj tseem tuaj yeem siv los ntxiv cov tshuaj tua kab mob antioxidant, ultraviolet absorbers thiab lwm txoj hauv kev kom ua tau zoo ncua kev yellowing ntawm PU steel hlau hose.
