Thaum tshav kub kub rwb thaiv tsev Low Water Absorption Hollow iav Spheres
Hollow iav microspheres muaj lub teeb yuag, ntim loj, thermal conductivity tsawg, siab compressive zog, thiab zoo fluidity. Lawv yog siv los ua cov khoom ntim khoom thiab cov khoom siv hluav taws xob hauv cov xim pleev xim, roj hmab, hloov cov yas, iav fiber reinforced plastics, pob zeb dag, putty thiab lwm yam lag luam; Hauv kev lag luam roj thiab roj av mining, kev ua tau zoo ntawm lawv cov kev ua haujlwm siab compression thiab tsis tshua muaj siab tuaj yeem ua rau muaj zog qis qis qis cement slurry thiab low-density drilling kua.
Hollow iav microspheres yog hollow iav spheres nrog me me, uas yog inorganic non-metallic cov ntaub ntawv. Qhov nruab nrab particle loj yog 28-120 microns, thiab qhov ceev yog 0.2-0.6 g / cm3. Nws muaj qhov zoo ntawm lub teeb yuag, tsis tshua muaj thermal conductivity, suab rwb thaiv tsev, siab dispersion, zoo hluav taws xob rwb thaiv tsev thiab thermal stability. Nws yog ib qho tshiab tsim cov khoom siv hnyav nrog ntau yam kev siv thiab kev ua haujlwm zoo heev.
1: Cov tsos xim yog dawb huv. Nws tuaj yeem siv dav hauv txhua yam khoom uas muaj cov kev xav tau rau cov tsos thiab xim.
2: Lub teeb tshwj xeeb lub ntiajteb txawj nqus thiab ntim loj. Qhov ceev ntawm hollow iav microspheres yog hais txog ib feem kaum ntawm qhov ntom ntawm cov khoom siv ib txwm siv. Tom qab sau, nws tuaj yeem txo qhov hnyav ntawm cov khoom, hloov thiab txuag ntau cov resins, thiab txo cov nqi khoom.
3: Nws muaj cov organic hloov pauv (lipophilic) nto. Hollow iav microspheres yog ib qho yooj yim rau ntub thiab tawg, thiab tuaj yeem sau rau hauv feem ntau cov thermosetting thermoplastic resins, xws li polyester, pp, pvc, epoxy, polyurethane, thiab lwm yam.
Hollow iav microspheres kuj muaj nrog cov txheej txheem conductive. Conductive txheej nrog optimized thickness muab spherical hais nrog zoo conductivity thiab shielding zog thaum tswj qhov hnyav-txuag txiaj ntsig txuam nrog hollow-core low-density cov ntaub ntawv. Cov kab hluav taws xob microbubbles no tsim nyog siv rau hauv kev siv tub rog, biotechnology, khoom siv kho mob, hluav taws xob, thiab lwm yam kev lag luam tshwj xeeb.

Kev siv tseem ceeb ntawm hollow iav microspheres:
1. Kev hloov kho ntawm nylon, PP, PBT, PC, POM, PVC, ABS, PS thiab lwm yam yas tuaj yeem txhim kho fluidity, tshem tawm cov iav fiber ntau, kov yeej warpage, txhim kho cov nplaim hluav taws xob, txo cov iav fiber ntau, thiab txo cov nqi tsim khoom.
2. Filling rigidity PVC, PP, PE, ua cov profiles, cov kav dej thiab cov ntawv txheeb, tuaj yeem ua rau cov khoom muaj kev ruaj ntseg zoo, txhim kho rigidity thiab kub tsis kam, txhim kho cov nqi khoom, txhim kho kev tsim khoom thiab txo cov nqi.
3. Ua rau 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 cov khoom ua haujlwm, ua kom cov zis ntau ntxiv thiab txo cov nqi.
