2021 Tuam Tshoj Tshiab Tsim Microspheres Hmoov Rau Cement Slurries - Kub Rwb Thaiv Tsev Qis Dej Nqus Hollow Iav Spheres - Kehui

Cov iav microspheres hollow muaj qhov hnyav sib dua, ntim loj, thermal conductivity qis, lub zog compressive siab, thiab fluidity zoo. Lawv yog siv los ua cov khoom fillers thiab lightening agents hauv cov xim pleev xim, roj hmab, modified plastics, iav fiber reinforced plastics, pob zeb dag, putty thiab lwm yam lag luam; Hauv cov roj thiab roj teb mining lag luam, lawv qhov kev ua tau zoo ntawm lawv qhov kev tiv thaiv siab compression thiab qis density tuaj yeem tsim cov cement slurry siab muaj zog qis thiab qis density drilling fluid.
Cov iav me me uas tsis muaj qhov (hollow glass microspheres) yog cov iav me me uas tsis muaj qhov (hollow glass spheres) uas muaj qhov me me, uas yog cov khoom siv inorganic uas tsis yog hlau. Feem ntau cov khoom me me yog 28-120 microns, thiab qhov ceev ntawm cov khoom yog 0.2-0.6 g/cm3. Nws muaj qhov zoo ntawm qhov hnyav sib dua, kev ua kom sov tsis kub, kev rwb thaiv suab, kev tawg zoo, kev rwb thaiv hluav taws xob zoo thiab kev ruaj khov ntawm thermal. Nws yog cov khoom siv tshiab uas tsis hnyav nrog ntau yam kev siv thiab kev ua tau zoo heev.
1: Cov xim zoo li yog dawb huv. Nws tuaj yeem siv dav hauv txhua yam khoom uas muaj qhov yuav tsum tau ua rau pom thiab xim.
2: Lub zog tshwj xeeb ntawm lub teeb thiab qhov loj. Qhov ceev ntawm cov iav microspheres hollow yog li ib feem kaum ntawm qhov ceev ntawm cov khoom siv ib txwm muaj. Tom qab sau, nws tuaj yeem txo qhov hnyav ntawm cov khoom, hloov thiab txuag tau ntau cov resins tsim tawm, thiab txo cov nqi khoom.
3: Nws muaj qhov chaw hloov kho organic (lipophilic). Cov iav microspheres hollow yooj yim rau ntub thiab tawg, thiab tuaj yeem sau rau hauv feem ntau thermosetting thermoplastic resins, xws li polyester, pp, pvc, epoxy, polyurethane, thiab lwm yam.

Cov iav me me uas muaj cov txheej txheej conductive kuj muaj. Cov txheej txheej conductive nrog qhov tuab zoo tshaj plaws muab cov khoom me me uas muaj cov khoom conductivity zoo thiab cov khoom tiv thaiv thaum tseem tswj tau qhov hnyav uas cuam tshuam nrog cov khoom siv hollow-core qis-density. Cov microbubbles conductive no tsim nyog rau kev siv hauv kev siv tub rog, biotechnology, cov khoom siv kho mob, cov khoom siv hluav taws xob, thiab lwm yam kev lag luam tshwj xeeb.

Cov ntsiab lus:

Cov kev siv tseem ceeb ntawm cov iav hollow microspheres:
1. Kev hloov kho cov nylon, PP, PBT, PC, POM, PVC, ABS, PS thiab lwm yam yas tuaj yeem txhim kho kev npliag, tshem tawm kev raug iav fiber, kov yeej kev sib txhuam, txhim kho cov khoom tiv thaiv hluav taws, txo kev siv iav fiber, thiab txo cov nqi tsim khoom.
2. Kev sau cov khoom siv PVC, PP, PE, tsim cov ntaub ntawv, cov kav dej thiab cov ntawv, tuaj yeem ua rau cov khoom muaj kev ruaj khov zoo, txhim kho kev ruaj khov thiab kev tiv taus kub, txhim kho kev ua tau zoo ntawm cov khoom, txhim kho kev ua haujlwm ntawm cov khoom thiab txo cov nqi.
3. Puv nrog PVC, PE thiab lwm yam cables thiab insulating sheath cov ntaub ntawv, nws tuaj yeem txhim kho cov khoom kub tsis kam, rwb thaiv tsev, acid thiab alkali tsis kam thiab lwm yam khoom thiab kev ua haujlwm ntawm cov khoom, nce cov zis thiab txo cov nqi.
