PVA hmoov puas muaj tiag?
Polyvinyl cawv (PVA) yeej muaj nyob rau hauv daim ntawv hmoov. Cov granules zoo li no zoo li hmoov nplej, tab sis lawv muaj cov khoom zoo kawg li thaum raug dej. PVA hmoov yog tsim los ntawm cov khoom siv raw los ntawm cov txheej txheem pulverization tshwj xeeb; nws qhov loj me feem ntau yog nyob nruab nrab ntawm 80 thiab 200 mesh, muab cov dej ntws zoo heev thiab ua haujlwm rau clumping. Ob chav kuaj thiab cov chaw tsim khoom lag luam nyiam nyiam cov hmoov daim ntawv, vim nws tso cai rau qhov hnyav dua thiab nrawm dua piv rau cov ntawv flake lossis fiber ntau.
Vim li cas thiaj xaiv daim ntawv hmoov?
High Dissolution Efficiency: Dissolves peb zaug sai dua li thaiv cov ntaub ntawv, yielding ib pob tshab gel tov nyob rau hauv tsuas yog tsib feeb.
Kev sib xyaw ua ke: Ua tiav qib molecular - kev sib xyaw ua ke thaum sib xyaw nrog lwm cov ntaub ntawv hmoov, xws li cov cement lossis gypsum.
Precise Control: Yooj yim ntsuas hauv feeb kom muaj nuj nqis- me me li 0.1 grams- siv lub ntsuas hluav taws xob.
Yooj Yim Cia: Nyob ruaj khov thiab tsis muaj degradation txog li ob xyoos thaum khaws cia hauv cov dej noo- pov thawj ntim.
Cov ntawv thov uas tsis xav tau
Tshaj li nws cov kev siv ntau hauv cov nplaum thiab cov khoom siv textile sizing, hmoov PVA pom niche - tseem txaus nyiam - daim ntawv thov hauv ntau qhov chaw:
3D Printing Support Material: Nws cov dej-soluble xwm simplifies tus ncej-processing ntawm complex 3D- luam tawm qauv.
Khawv koob Props: Siv los tsim "cov ntawv tsis paub" uas ploj mus thaum sib cuag nrog dej.
Horticultural Water Retainer: Tsuas yog ib gram ntawm hmoov tuaj yeem nqus tau txog 100 npaug ntawm nws qhov hnyav hauv dej.
DIY Crafts: Cov khoom tseem ceeb tseem ceeb rau kev ua hauv tsev "crystal slime."
Thaum tuav cov hmoov, nws raug nquahu kom hnav lub ntsej muag plua plav kom tsis txhob nqus cov khoom zoo, uas yuav ua rau ua pa ua pa.
