Qhov siv tau ntawm cov kev siv kub siab-tiv taus cov txheej txheem ntawm PP / PU CASTERS?

Daim ntawv thov ntawm high-kub-resistant txheej rau pp (polypropylene) thiab pu (polyurethaners tuaj yeem them nyiaj rau cov khoom siv kub tsis txaus ntawm cov khoom siv hluav taws xob. Cov txiaj ntsig tshwj xeeb yog raws li hauv qab no:

1. Txhim kho txoj kev txwv kub sab saud
Cov khoom siv hauv paus ntawm PP casters feem ntau muaj qhov kub tsis kam ntawm 60-80 degree, uas tuaj yeem soften yooj yim thiab deform thaum muaj kub. PU CASSERS muaj kub tsis kam ntawm kwv yees li 80-100 degree, tab sis muaj kev pheej hmoo uas laus thiab tawg nyob rau hauv lub caij nyoog kub siab. Txheej txheem (xws li Silicone thiab Ceramic-based txheej) tuaj yeem nce qhov ntsuas kub kom muaj 120-150℃rau cov bakery kev cob qhia thiab xim hlau thiab xim hlau cov khoom siv.

2. Nce Cov Khoom Siv Laus thiab Kev Ua Haujlwm degradation
Nyob rau hauv cov kev mob siab, PP / PP muaj kev cuam tshuam rau molecular chart breakage vim yog thermal oxidation, uas ua rau embrittlement thiab chipping. Cov txheej txheej txheej ceev cov yeeb yaj kiab tuab, thaiv cov qauv kub ncaj qha rau cov qauv molecular tshwm sim los ntawm cov qauv molecular xws li kev ua kom tawv me me, thiab kev tawg ntawm lub neej pabcuam.

3. Txhim kho hnav thiab corrosion tsis kam
Kev kub siab feem ntau koom nrog kev sib cuag nrog roj, av, thiab tshuaj me. Txheej tuaj yeem nce cov npoo hardness ntawm cov casters (piv txwv li, txo kev sib txhuam ntawm cov roj, thiab ua kom txo qis acids, thiab cov hauv paus, tswj kev ncaj ncees ntawm lub log nto.

Note: The coating's effectiveness is affected by thickness and application process. Too thin a coating can easily peel. Extremely high temperatures (e.g., >150 qib) tseem yuav tsum muaj tshav kub-resistant pob khoom siv, thiab txheej tsuas yog muab kev tiv thaiv kev tiv thaiv. Xaiv cov qauv txheej txheej tsim nyog raws li qhov ntsuas kub tshwj xeeb thiab tsis txhob muaj kev ntseeg siab.
