Khoom Ikev taw qhia
Polyurethane (PU) valve cores tau teev tseg qhov kev puas tsuaj yog qhov tseem ceeb ntawm lub neej - txwv tsis pub hom - slurry kab, siab - cov khoom tawm, siab - voj voog dynamic sealing, thiab cov ntawv thov uas cov roj hmab sib xyaw ua ke yuav hnav los ntawm ib feem ntawm qhov kev pab cuam lub sijhawm. PU tsis yog cov khoom siv roj hmab; Nws yog ib qho elastomeric polymer uas nws lub zog txhua yam thiab kev ua haujlwm tsis zoo tshaj li cov txheej txheem vulcanizate, thaum khaws cov elastic raws li xav tau rau kev sib khi ua haujlwm.
Kev khiav hauj lwm kub yog los ntawm -40℃mus rau +70℃. Rau kev pabcuam aqueous, cov kua dej kub yuav tsum tau lees paub ua ntej qhia PU.

Taw qhia txog cov txheej txheem thiab cov khoom siv
TGE Polyurethane Valve Cores yog tsim los ntawm cam khwb cia elastomer los yog compression -moulded millable pos hniav txheej txheem nyob ntawm geometry thiab ntau lawm ntim. Hauv TGE, peb siv cov txheej txheem molding. Millable PU cov pos hniav yog ua tiav zoo ib yam li cov pa roj hmab sib xyaw ua ke thiab ua kom nruj dua - kev ua siab ntev sib koom ua ke.
Kev npaj hlau substrate ua raws tib qhov kev txhaj tshuaj - tawg thiab nplaum primer ib ntus siv thoob plaws peb cov khoom lag luam. Isocyanate-raws li kev sib txuas tshuab yog siv rau PU- rau- hlau sib txuas, thiab lub interface yog tshwj xeeb tshaj yog rhiab heev rau qhov chaw paug - degreasing thiab priming cov kauj ruam yog ua nyob rau hauv ib tug tswj cheeb tsam. Hardness thiab formulation hom (polyester vs. polyether PU) yog xaiv los ntawm daim ntawv thov: polyester qib rau siab tshaj plaws puas thiab roj kuj; polyether qib uas hydrolysis tsis kam yog qhov tseem ceeb.
Tej kev siv
Cov ntawv thov rau Polyurethane Valve Core muaj xws li:
Mining thiab ntxhia ua slurry li qub (siab-khoom, abrasive media)
Sand thiab gravel processing - kev faib tawm thiab thauj tswj li qub
High -dej siab jetting system li qub
Hydraulic lub tog raj kheej valve Cheebtsam - siab -cycle dynamic sealing
Coal npaj cog kev khiav tswj li qub
Oilfield fracturing khoom (siab-siab, luv- kev pabcuam sijhawm)
Qhov zoo
Hauv kev pabcuam abrasive, qhov kev ntsuas kev ua tau zoo tsis yog cov khoom siv tus nqi ib chav tsev tab sis cov khoom ntim khoom siv rau ib chav tsev ntawm lub sijhawm ua haujlwm. PU's abrasion resistance routinely ncua kev pab cuam los ntawm peb mus rau tsib lub sij hawm txheeb ze rau NBR hauv slurry daim ntaub ntawv - ib qho tseem ceeb uas txiav txim siab tag nrho cov nqi tu thiab unplanned downtime zaus ntau ncaj qha tshaj li tus nqi yuav.
Peb xaiv PU qib rau daim ntawv thov. Qhov chaw ua haujlwm nyob rau hauv NBR lub peev xwm, peb yuav pom zoo NBR. Qhov twg puas yog qhov txwv, peb muab PU nrog cov hom sib xyaw, hardness, thiab kev sib txuas ua ke nrog rau koj qhov nruab nrab thiab lub luag haujlwm.
FAQ
Q: Qhov kev lag luam twg yog koj cov khoom siv rau?
A: Peb cov khoom tau siv rau ntau yam kev lag luam xws li kev tsheb ciav hlau, kev tsim kho tshuab, aviation, marine, tsheb, thiab lwm yam.
Q: Koj puas ua cov roj hmab sib xyaw ntawm koj tus kheej lossis koj puas yuav los ntawm lwm tus?
A: Peb ua cov roj hmab sib xyaw ntawm peb tus kheej, nrog ntau lub tshuab sib xyaw roj hmab hauv peb lub hoobkas. Peb tseem tuaj yeem tsim cov qauv roj hmab kom tau raws li qhov yuav tsum tau ua ntawm kev siv sib txawv.
Q: Peb puas tuaj yeem tuaj xyuas koj lub Hoobkas ua ntej tso qhov kev txiav txim?
A: Yog lawm, peb txais tos cov neeg siv khoom tuaj xyuas kom muaj kev sib raug zoo rau kev lag luam.
