Yi nazarin fa'idodi da rashin amfanin injinan polyurethane na ƙarfe na masana'antu

Simintin polyurethane na ƙarfe wani nau'in siminti ne mai kayan polyurethane, wanda aka haɗa shi da ƙarfen siminti, ƙarfen tsakiya ko farantin ƙarfe, wanda yake da shiru, nauyi mai jinkiri kuma mai araha, kuma ya dace da yawancin yanayin aiki.
Yawanci, girman injinan casters na masana'antu yana tsakanin inci 4-8 (100-200mm), tare da ƙafafun polyurethane mafi kyau. Tayoyin polyurethane suna da juriyar gogewa mai kyau, iya aiki mai yawa, hanyoyin sarrafawa daban-daban, amfani mai faɗi, da juriya mai kyau ga mai, ozone, tsufa, radiation, ƙarancin zafin jiki, da sauransu, kyakkyawan ƙarfin sauti, ƙarfin manne mai ƙarfi, kyakkyawan juriyar halitta da kuma dacewa da jini.

Babban fasalin polyurethane casters shine waɗannan abubuwan:
1. Babban kewayon aiki mai daidaitawa. Ta hanyar zaɓar kayan aiki da daidaita dabarar, ana iya zama mai sassauƙa a cikin wasu canje-canje a cikin wasu alamun aiki na zahiri da na injiniya, don biyan buƙatun mai amfani na musamman kan aikin samfura. Misali, ana iya yin polyurethanes elastomers su zama na'urorin bugawa masu laushi na roba da na'urorin ƙarfe masu tauri don biyan buƙatun masu amfani daban-daban.
2. Mafi kyawun juriya ga gogewa. A gaban ruwa, mai da sauran yanayin aikin danshi, juriyar lalacewa na masu jefa polyurethane ya fi na kayan roba na yau da kullun sau da yawa zuwa sau da yawa.

3. Hanyoyi daban-daban na sarrafawa da kuma amfani mai faɗi. Ana iya ƙera elastomer na polyurethane ta hanyar ƙera filastik, haɗawa da kuma ƙera ƙarfe (yana nufin MPU); kuma ana iya ƙera shi ta hanyar roba mai ruwa, ƙera siminti ko feshi, ƙera tukunya da ƙera centrifugal (yana nufin CPU); kuma ana iya ƙera shi ta hanyar allura, fitar da shi, ƙera shi, ƙera busa da sauran hanyoyin (yana nufin CPU).
4. Yana jure wa mai, ozone, tsufa, radiation, ƙarancin zafin jiki, ingantaccen watsa sauti, ƙarfin manne mai ƙarfi, kyakkyawan jituwa tsakanin halittu da kuma dacewa da jini.

Duk da haka, polyurethane elastomers suna da wasu rashin amfani, kamar zafi mai yawa na ciki, juriya ga zafin jiki mai yawa gabaɗaya, musamman rashin juriya ga danshi da zafi, rashin juriya ga ƙarfi mai ƙarfi na polar da kuma ƙarfi mai ƙarfi na acid da alkali.
