Main Ua haujlwm ntawm Mica
Av qhuav mica hmoov ntawm Huajing yog qhov sib tw hauv nqe thiab ruaj khov nyob rau hauv kev ua tau zoo. Lub siab purity mica hmoov ua los ntawm kev sib tsoo tsis hloov pauv txhua yam khoom ntiag tug. Lub sijhawm tag nrho ntau lawm, peb txais tag nrho cov kab ke ntim tshuab kom paub tseeb cov khoom zoo; Cov txheej txheem tshuaj ntsuam siv cov txheej txheem patent kom ntseeg tau qhov ruaj khov ntawm cov khoom zoo thiab faib kom zoo, tom qab ntawd txaus siab rau qee tus neeg siv cov lus thov siab dua. Raws li tus yam ntxwv zoo dua, Huajing mica hmoov yog siv dav ua cov khoom ntim hauv yas.
Ntawv thov ntawm Mica hauv PP
Mica hmoov muaj cov hluav taws xob zoo heev, lub siab tawg, hluav taws xob qis tsis tu ncua, tsis tshua muaj qhov poob qis thiab qhov zoo arc kuj. Nyob rau tib lub sijhawm, mica muaj qis hygroscopicity thiab siab thermal deformation kub thaum mica siv los ua cov muab tub lim, uas tau txais txiaj ntsig los tswj cov khoom hluav taws xob hauv cov huab cua noo thiab qhov kub dua. Piv txwv li, thaum 50% mica ntxiv rau PP, qhov hluav taws xob tawg yog ntau tshaj ob npaug. Daim ntawv thov ntawm mica hloov PP hauv tsheb thiab cov khoom siv hauv tsev los tsim cov tsheb khiav tsheb, lub taub hau tiv thaiv ntiv nplhaib, lub kiv cua lub cev thiab lwm qhov chaw tuaj yeem pom tseeb nws txoj kev ua kom nws nruj, tiv tshav kub, seem ruaj ntseg thiab molding shrinkage.
Daim ntawv thov ntawm Mica hauv PP-R
PP-R yeeb nkab yog hom tshiab ntawm PP random copolymer ntsuab lub tsev cov khoom siv dav siv hauv xyoo tsis ntev los no. Nws qhov kub tsis kam yog ntau dua lossis sib npaug txog 90 degrees, tus nqi qis thiab siv yooj yim. Cov yeeb yaj kiab PP-R nrog mica muaj lub zog zoo, zoo thaum tshav kub ua haujlwm, muaj zog tiv thaiv corrosion, thiab tus nqi raug txo ntau heev, yog li nws muaj qhov kev nthuav dav ua lag luam txhim kho.
