⑥ Polyether series - polyether thiab roj sib xyaw ua ke, tiv taus cua sov thiab tshuaj lom neeg, feem ntau yog siv rau hauv qee yam kev lag luam roj hmab nrog cov kev txwv ntawm cov roj silicone. Tus nqi siab dua piv rau cov roj silicone series.
Cov Kev Cai Ua Haujlwm rau Cov Neeg Tso Tawm
Lub luag haujlwm ntawm tus neeg sawv cev tso tawm yog cais cov khoom kho, pwm tawm ntawm pwm, ua rau cov khoom du thiab sib npaug thiab xyuas kom meej tias pwm siv tau ntau zaus. Cov kev cai ua tau zoo tshwj xeeb yog raws li nram no:
Cov Khoom Tso Tawm (Lubricity):
Tus neeg sawv cev tso tawm yuav tsum tsim ib daim zaj duab xis nyias nyias thiab xyuas kom meej tias txawm tias cov khoom pwm uas muaj cov duab nyuaj muaj qhov loj me meej.
Kev Tso Tawm Zoo:
Tus neeg sawv cev tso tawm yuav tsum tswj tau nws qhov ua tau zoo ntawm ntau zaus siv yam tsis tas yuav rov siv dua ntau zaus.
Qhov Nto du thiab zoo nkauj:
Qhov saum npoo ntawm cov khoom pwm yuav tsum du thiab zoo nkauj, tsis muaj hmoov av vim yog qhov nplaum ntawm cov tshuaj tso tawm.
Kev Sib Txuas Zoo Tom Qab Ua Haujlwm:
Thaum tus neeg sawv cev tso tawm hloov mus rau cov khoom molded, nws yuav tsum tsis txhob cuam tshuam tsis zoo rau cov txheej txheem tom ntej xws li electroplating, kub stamping, luam ntawv, txheej, lossis kev sib txuas.
Yooj Yim ntawm Daim Ntawv Thov:
Tus neeg sawv cev tso tawm yuav tsum yooj yim siv sib npaug thoob plaws qhov chaw pwm.
Kev Tiv Thaiv Kub:
Tus neeg sawv cev tso tawm yuav tsum tiv taus qhov kub siab uas koom nrog hauv cov txheej txheem molding yam tsis muaj kev puas tsuaj.
Kev Tiv Thaiv Xim:
Tus neeg sawv cev tso tawm yuav tsum tiv thaiv kev ua qias tuaj lossis kev pleev xim ntawm cov khoom pwm.
Kev Ua Pwm Zoo thiab Kev Ua Haujlwm Zoo:
Tus neeg sawv cev tso tawm yuav tsum pab txhawb cov txheej txheem molding thiab pab txhawb rau kev ua haujlwm siab.
