Ntxiv hollow iav hlaws rau cov khoom siv roj hmab tuaj yeem nqa tau ntau yam zoo:
1 、 Qhov hnyav txo
Cov khoom siv roj hmab kuj mus rau lub teeb yuag, cov kev taw qhia ruaj khov, tshwj xeeb tshaj yog cov ntaub ntawv loj ntawm microbeads roj hmab ib leeg, los ntawm cov pa ntom ntom ntawm 1.15g / cm³ lossis yog li, ntxiv 5-8 feem ntawm microbeads, txo qis rau 1.0g / cm³ (feem ntau hu ua "floating on the water"), muaj qee qhov ntawm R & D muaj peev xwm ntawm cov neeg siv khoom. 0.85g / cm³, txo qhov ntom ntawm cov roj hmab, khau thiab tib qhov xwm txheej ua ntej qhov hnyav ntawm 20% los yog li ntawd. Tam sim no, qee cov neeg siv khoom nrog qee qhov R & D muaj peev xwm yuav ua rau qhov ceev 0.9 lossis txawm tias 0.85g / cm³ los ntawm kev ntxiv microbeads, uas txo cov roj hmab ntom ntom, thiab qhov hnyav ntawm nkawm khau yuav raug txo los ntawm 20% raws li qhov xwm txheej ua ntej.
2. Thaum tshav kub kub rwb thaiv tsev
Lub hollow qauv ntawm hollow iav hlaws muab cov hlaws uas tsis tshua muaj thermal conductivity, raws li cov thermal conductivity tsawg ntxiv rau cov khoom siv roj hmab tuaj yeem ua tau zoo thermal rwb thaiv tsev zoo, xws li hauv cov thermal rwb thaiv tsev pads, thermal rwb thaiv tsev boards thiab lwm yam khoom siv.
3 、 Lub suab nqus thiab txo suab nrov
Nyob rau hauv lub hollow iav hlaws dai yog nyias roj, suab yoj nyob rau hauv qhov no yuav tsis muaj zog, nyob rau hauv ib tug tej yam ntxiv mus ua si ib tug zoo heev nyhuv ntawm lub suab nqus thiab suab nrov txo.
4 、 Kev ruaj ntseg zoo
Beads puag khoom yog iav nrog tsawg coefficient ntawm thermal expansion, zoo seem stability thaum raug thermal poob siab, ntxiv rau cov khoom siv roj hmab yuav muab cov khoom zoo dua dimension stability.
Cov lus qhia rau kev siv hauv kev ua:
1, Roj hmab cov khoom lag luam feem ntau yog feem ntau cov khoom siv hluav taws xob tsis sib haum, thiab cov pob ntseg ntawm cov tshuab hluav taws xob yog ib nrab ntawm cov khoom siv tshuab
2, hollow iav hlaws muaj cov qauv sib txawv thiab cov tsis sib xws, raws li cov khoom sib txawv thiab cov khoom yuav tsum tau xaiv cov khoom siv hlaws zoo yog qhov tseem ceeb heev, St. Leite pom zoo kom siv HL38, HL42, HL50, HS38, HS42 hauv cov khoom siv roj hmab.
3, thaum siv lub tshuab ua kom zoo, muaj lub rotor ntawm cov khoom siv roj hmab shear, cov hlaws tsis tuaj yeem zam los ntawm lub zog shear, kom deb li deb tau kom txo tau lub sij hawm ntawm cov hlaws hauv kev ua kom zoo, nws raug nquahu kom ntxiv cov hlaws dai kom zoo kom paub meej tias cov hlaws ntxiv rau kev ua kom zoo dua 3-5min tuaj yeem faib ua ke; nyob rau hauv lub tshuab refining, cov menyuam qhov sib nrug thiab lub sij hawm refining ntawm crushing ntawm cov hlaws dai muaj kev cuam tshuam ntau dua, nws pom zoo tias cov menyuam qhov sib nrug> 2 hli, lub sijhawm ua kom zoo yuav tsum tsis txhob ntev dhau; Zuag qhia tag nrho shear quab yuam ntawm ib qho ntsia hlau extruder yog me me, kuj hais lus, qhov cuam tshuam ntawm microbeads yog me me, nws raug nquahu kom nce qhov kub ntawm extrusion los ntawm 5 ℃, txo cov viscosity ntawm cov khoom yog ntau conducive rau extrusion molding, txo cov microbeads tawg.
