Cov khoom caster uas tau coj khaub ncaws zoo dua?

Ntawm cov khoom siv feem ntau siv rau cov casters, polyurethane (pA) thiab nylon tshwj xeeb yog hnav-resistant. Cov lus raug hloov kho tshwj xeeb thiab hnav-resistant cov yam ntxwv muaj raws li hauv qab no:

1. POLYURETHANE (PU) LOG: Coj kev hnav kev tawm tsam thiab muaj zog yoog raws li cov xwm txheej

Hnav-resistant txoj ntsiab cai: PU khoom siv muaj cov qauv molecular, muaj qhov sib zog ntawm 85-95), thiab muaj ob qho elasticity thiab rigidity. Thaum dov, thaj chaw tiv tauj nrog hauv av yog niaj hnub sib txhuam, kev sib txhuam coefficient yog tsawg, thiab kua muag yeem yog muaj zog. Nws tsis yooj yim los poob tawm lossis tawg vim muaj kev cuam tshuam lossis dov.

Qhov zoo tshaj plaws cov xwm txheej:
Kev kho mob ib puag ncig (xws li cov khoom siv kho mob uas muaj nyob hauv cov kab mob no): PU log tau hnav zoo heev ntawm qhov chaw du zoo li cov vuas thiab PVC. Nyob rau tib lub sijhawm, lawv tau nyob ntsiag to thiab poob siab-nqus cov yam ntxwv kom tsis txhob cuam tshuam nrog pawg ntseeg ib puag ncig. Lawv kuj tseem tiv taus corrosion los ntawm cov tshuaj tua kab mob feem ntau thiab tsim nyog rau cov tsheb khiav tau zoo, cov txaj khomob thiab lwm yam khoom siv.

Cov cuab yeej siv hluav taws xob: ntawm cov cement, epoxy pem teb thiab lwm qhov chaw, cov kev pabcuam tsis kam tshaj li ntawm cov roj hmab log, thiab lub neej pabcuam feem ntau yog 2-3 zaug ntawm cov log tsheb roj hmab.
Cov kev txwv: thaum siv rau lub sijhawm ntev ntawm cov nplaim ntxhib (xws li cov av nkos) nrog cov khoom siv hnyav, hnav tsis zoo rau cov nylon log.

2. Nylon (pa) log: hnav zoo dua nyob hauv ib puag ncig heev

Hnav Cov Cai: Nylon yog lub zog ua kom muaj zog (Ntug dej D 70- Nws tsis yooj yim los hnav kev sib txhuam siab ntawm kev sib txhuam siab thiab cov khoom lag luam siab.

Cov xwm txheej zoo:

Cov cuab yeej hnyav: Rau cov casters nrog lub nra ntau dua 200kg (xws li cov tsheb kho mob muaj cov txiaj ntsig zoo hauv kev hnav tsis pom zoo. Nyob rau hauv av nrog ntau gravel thiab hlau khib nyiab (xws li cov tsev kho mob logistics warehouses), nws tsis yooj yim los ntawm cov khoom sib tw.

Qhov chaw hnyav ib puag ncig: hauv cov hluav taws xob kub thiab roj carming kub (xws li cov chaw ua haujlwm ntawm lub tsev kho mob
Cov kev txwv: muaj zog heev, tsis zoo elasticity, nrov nrov thaum dov, tsis haum rau kev siv nyiaj pab rau kev ua kom ntsiag to.

3. Kev sib piv ntawm kev hnav tsis kam ntawm lwm cov ntaub ntawv

Roj Hmab Log: ntuj roj hmab tau hnav tsis zoo thiab tsuas yog tsim nyog rau lub teeb thauj khoom thiab siv tsawg zaus; Roj roj hluav taws xob (xws li cov roj hmab nitrile) tau txhim kho cov roj coj tsis kam, tab sis nws tseem tsis zoo li pu thiab nylon, thiab yog yooj yim corroded los ntawm roj.

Thermoplastic elastomer (TPE) log: Cov hnav tsis kam yog zoo dua li roj hmab, tab sis qis dua li pu. Nws yog qhov haum rau lub teeb loads thiab scenes nrog cov kev cai siab ib puag ncig (xws li cov menyuam yaus kho mob). Ntev ntev loads yog nquag mus nto hnav thiab fluffing.

Lub ntsiab
Nylon log yog nyiam rau cov khoom siv hnyav, ntxhib chaw lossis pu log yog nyiam rau kev kho mob ntsiag to scenent, nruab nrab thiab lub teeb ntim khoom thiab cov chaw du. Ob qho tib si tau zoo heev hauv kev hnav tsis kam. Cov kev xaiv tshwj xeeb yuav tsum tau kev txiav txim siab rau kev txiav txim siab raws li cov khoom siv thauj khoom, cov khoom lag luam hauv pem teb, thiab tshuaj ib puag ncig) kom ua kom lub neej tshwj xeeb ntawm cov neeg ua haujlwm.
