Dab tsi yogCov ntawv thov thiab cov txiaj ntsig ntawm polyurethane elastewmer khoom?
Polyurethane elastomers, raws li lub siab -}}}}}}}} agent peeler, tau siv dav hauv ntau yam kev lag luam vim lawv lub cev thiab cov kws kho tshuab. Piv rau cov khoom siv roj hmab tsoos, polyurethane elastomers muaj lub zog siab dua, corrosion tsis kam, thiab siv sijhawm zoo tshaj plaws rau ntau cov ntawv thov engineering thiab kev lag luam. Hauv qab no, peb yuav tshuaj xyuas cov yam ntxwv thiab qhov zoo ntawm polyurethane elastomers hauv peb qhov chaw thov raug cai: Polyurethane chais, Liners, thiab Casters.
1. Polyurethane Chais
Polyurethane cov zaub mov tau ua siv kua polyurethane roj hmab los ntawm kev ua kom cov txheej txheem casting, muab cov txiaj ntsig tseem ceeb tshaj li cov roj roj roj. Ua ntej, lawv lub zog txhua yam yog 2 txog 3 zaug ntawm cov roj hmab ntuj, thaum lawv cov coj tsis kam yog 5 txog 10 zaug siab dua. Vim yog lawv cov zog compression tsis kam, polyurethane cov ntaub kom ua tau ruaj khov txawm nyob hauv siab thiab siab}} ceev tej xwm txheej. Lawv kuj muaj ntau yam kev nyuaj siab thiab khaws cia siab zoo ntawm qib siab, muaj tus yam ntxwv tsis pom nyob hauv lwm hom roj hmab.
Polyurethane cov ntaub ntawv muaj cov npoo av siab ua tiav thiab zoo tshaj plaws tshuab, tso cai rau lawv mus rau daim ntawv cog lus zoo nrog cov khoom lag luam hlau. Yog li ntawd, lawv yog tshwj xeeb yog tsim nyog rau siv nyob rau hauv cov kab tshwj xeeb thiab siab pressures. Tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov xws li luam ntawv, txheej, kev ua haujlwm textile, thiab cov khoom siv polyurethane, tau ua cov khoom siv tsis tseem ceeb, tau muaj qhov tsis tseem ceeb ntawm cov khoom siv tseem ceeb.
2. Hnab polyurethane
Polyurethane Liners yog cov khoom siv polymer siab uas ua ke ntawm cov txiaj ntsig roj hmab thiab yas, muab cov khoom siv tsis kam ua tsis kam thiab cov khoom siv mechanical. Piv rau cov khoom siv roj hmab ib txwm muaj, polyurethane hnab muaj polyurethane muaj cov tensior tensile lub zog, elongation thaum tawg, thiab kua muag yeem. Lawv kuj muaj cov elastness adjness haum ntau, tswj hwm siab nyob rau hauv ntug dej A10 rau Shore D98 Hardness ntau yam, nrog rau cov roj tsis zoo thiab tshuaj lom neeg.
Polyurethane Linters tseem muaj cov kev cuam tshuam zoo thiab kev nqus cov roj, thiab lawv cov roj thiab cov roj thiab cov roj npau taws siv nyob rau hauv ib puag ncig. Lawv yog qhov tsim nyog tshwj xeeb rau cov ntaub ntawv hauv kev lag luam xws li mining, metallurgy, thiab kev tsim kho, qhov chaw uas lawv siv tau zoo dua kev hnav thiab txuas ntxiv cov cuab yeej siv tshuab.
3. Polyurethane Casters (Log)
Polyurethane Casters, uas yog qhov kev xaiv muaj cov khoom siv muaj ntau, yog cov tshuab ua haujlwm zoo tshaj plaws, lub kua muag tiv, thiab corrosion tsis kam. Cov hnav tsis kam ntawm polyurethane casters yog 5 zaug ntawm cov roj hmab ntuj, thiab lawv cov roj ua haujlwm yog 3 txog 5,5% ntawm hardness, ua rau lawv yoog tau rau ntau qhov chaw ua haujlwm.
Qhov hloov tau yooj yim, muaj zog tensile zog, cuam tshuam lub zog, thiab siab} kub, hnyav} kev tso tawm, thiab cov chaw ib puag ncig. Txawm hais tias nyob rau hauv cov cuab yeej kho mob, cov khoom siv hluav taws xob, tshuab hluav taws xob, polyurethane castters muab kev ua haujlwm zoo dua, ua kom muaj kev ua haujlwm zoo thiab ntev} {5 5}} lub sij hawm termability.
