Zochita za wollastonite

Wollastonite ndi wamtundu umodzi wa silicate mtundu wa ore, wokhala ndi mamolekyu a Ca3 [Si3O9], ndipo nthawi zambiri amakhala ngati ulusi, singano, flakes, kapena ma radiation.Wollastonite nthawi zambiri imakhala yoyera kapena yotuwa, yonyezimira.Wollastonite ili ndi mawonekedwe apadera a crystal morphology, chifukwa chake ili ndi kutchinjiriza bwino, katundu wa dielectric, komanso kutentha kwambiri komanso kukana nyengo.Katunduwa ndiwonso maziko owunikira momwe msika wa wollastonite akugwiritsidwira ntchito.

1. Zopaka
Wollastonite, yomwe ili ndi index yotsika kwambiri, yophimba mwamphamvu, komanso kuyamwa kwamafuta ochepa, ndiyodzaza zopangira zomangira, zokutira zotsutsana ndi dzimbiri, zokutira zopanda madzi komanso zosayaka moto.Ikhoza kupititsa patsogolo mphamvu zamakina za zokutira monga kukana kuchapa, kukana kwa nyengo, kukana kwa ming'alu, ndi kupindika, komanso kukana kwa dzimbiri, kukana nyengo, ndi kukana kutentha.Ndizoyenera kwambiri kupanga utoto woyera wapamwamba kwambiri komanso utoto wowoneka bwino komanso wowoneka bwino;Popanda kukhudza kuphimba ndi washability wa ❖ kuyanika, wollastonite akhoza m'malo 20% -30% titaniyamu woipa mu mkati khoma dongosolo utoto utoto, kusintha pH mtengo wa dongosolo, ndi kuchepetsa mtengo kupanga ❖ kuyanika.

2. Zoumba
Wollastonite itha kugwiritsidwa ntchito kwambiri pazinthu za ceramic monga matailosi onyezimira, zoumba tsiku ndi tsiku, zoumba zaukhondo, zoumba zaluso, zoumba zapadera zosefera, glaze ya ceramic, insulating high-frequency electric ceramics, lightweight ceramic molds, and electronic ceramics.Itha kusintha kuyera, kuyamwa kwamadzi, kukulitsa kwa hygroscopic, komanso kukana kuzizira kofulumira komanso kutentha kwa zinthu za ceramic, kupangitsa kuti zinthu ziwoneke bwino komanso zowala, ndikuwonjezera mphamvu komanso kukana kukakamiza.Mwachidule, ntchito za wollastonite muzoumba zikuphatikizapo: kuchepetsa kutentha kwa kuwombera ndikufupikitsa kuwombera;Kuchepetsa kuchepa kwa sintering ndi kuwonongeka kwa zinthu;Kuchepetsa kukula kwa hygroscopic kwa thupi lobiriwira komanso kufalikira kwamafuta panthawi yowombera;Kupititsa patsogolo mphamvu zamakina a mankhwala.

3. Mpira
Wollastonite imatha kulowa m'malo ambiri a titaniyamu woipa, dongo, ndi lithopone mu rabara yamitundu yopepuka, kuchitapo kanthu kolimbikitsa ndikuwongolera luso lophimba lamitundu yoyera, ndikuchita ntchito yoyera.Makamaka pambuyo organic kusinthidwa, padziko wollastonite osati lipophilicity, komanso chifukwa cha iwiri nsinga za kuchitira wothandizila sodium oleate mamolekyulu, akhoza nawo vulcanization, kumapangitsanso mtanda kugwirizana, ndipo kwambiri kumapangitsanso kulimbikitsa kwenikweni.

4. Pulasitiki
Kukaniza kwambiri, kutsika kwa dielectric mosakhazikika, komanso kuyamwa kwamafuta ochepa a wollastonite kumapangitsa kuti zabwino zake mumakampani apulasitiki ziwonekere kuposa zida zina zopanda zitsulo.Makamaka pambuyo pa kusinthidwa, kuyanjana kwa wollastonite ndi mapulasitiki kumakhala bwino kwambiri, komwe kungathe kupititsa patsogolo katundu wa pulasitiki ndikuonetsetsa kuti kutentha kumatenthedwa, kutsika kwa dielectric, kuyamwa kwamafuta ochepa, ndi mphamvu zamakina apamwamba.Zingathenso kuchepetsa mtengo wa mankhwala.Wollastonite imagwiritsidwa ntchito kwambiri popanga nayiloni, yomwe imatha kupititsa patsogolo mphamvu yopindika, kulimba kwamphamvu, kuchepetsa kuyamwa kwa chinyezi, ndikuwongolera kukhazikika kwa mawonekedwe.

5. Kupanga mapepala
Wollastonite ili ndi index yotsika kwambiri komanso yoyera kwambiri, ndipo ngati chodzaza, imatha kukulitsa mawonekedwe ndi kuyera kwa pepala.Wollastonite imagwiritsidwa ntchito popanga mapepala, ndipo maukonde opangidwa ndi wollastonite plant fiber ali ndi mawonekedwe a microporous, omwe amathandizira kuyamwa kwa inki pamapepala.Panthawi imodzimodziyo, chifukwa cha kusalala bwino komanso kuchepetsa kuwonekera, kumawonjezera kusindikizidwa kwa pepala.Wollastonite imasokoneza kumanga kwa ulusi wa zomera, zomwe zimapangitsa kuti zikhale zosakhudzidwa ndi chinyezi, kuchepetsa hygroscopicity ndi mapindikidwe, ndikuwonjezera kukhazikika kwa pepala.Malinga ndi zofunikira zamapepala, kudzaza kwa wollastonite kumasiyana 5% mpaka 35%.Kuyera, dispersibility, ndi mlingo wa ultrafine wophwanyidwa wollastonite ufa akhala bwino kwambiri, amene akhoza m'malo titanium dioxide ngati pepala filler.

6. Metallurgical chitetezo slag
Wollastonite ili ndi mawonekedwe otsika osungunuka, kutsika kwa kutentha kwapamwamba kwambiri, komanso ntchito yabwino yotchinjiriza, ndipo imagwiritsidwa ntchito kwambiri pakuponyera kosalekeza koteteza.Poyerekeza ndi nonwollastonite zoteteza slag, metallurgical zoteteza slag zochokera wollastonite ali ndi ubwino zotsatirazi: khola ntchito ndi kusinthasintha lonse;Ilibe madzi a crystalline ndipo imakhala ndi kutaya kochepa pa kuyaka;Ali ndi luso lamphamvu la adsorb ndi kusungunula ma inclusions;Ali ndi kukhazikika kwadongosolo;Ali ndi ntchito zabwino kwambiri zazitsulo;Amakhala aukhondo, athanzi, komanso okonda zachilengedwe;Ikhoza kusintha khalidwe ndi mphamvu ya mosalekeza kuponya kupanga.

7. Kukangana zinthu
Wollastonite ili ndi katundu wonga singano, kutsika pang'ono, komanso kukana kugwedezeka kwamafuta, zomwe zimapangitsa kuti ikhale m'malo mwa asbestosi wamfupi wa fiber.Zipangizo zomangira zomwe zimakonzedwa posinthana ndi asibesitosi wokhala ndi friction coefficient wollastonite zimagwiritsidwa ntchito makamaka m'magawo monga ma brake pads, ma plug ma valve, ndi zowomba zamagalimoto.Pambuyo kuyezetsa, magwiridwe antchito onse ndi abwino, ndipo mtunda wa braking ndi moyo wautumiki zimakwaniritsa zofunikira.Kuphatikiza apo, wollastonite imathanso kupangidwa kukhala ngati ubweya wa mchere ndi zina zolowa m'malo mwa asibesitosi monga kutchinjiriza mawu, zomwe zimatha kuchepetsa kwambiri kugwiritsa ntchito asibesitosi ndipo ndizopindulitsa pakuteteza chilengedwe ndikuwonetsetsa kuti anthu ali ndi thanzi.

8. Elekitirodi yowotcherera
Kugwiritsa ntchito wollastonite monga chophikira chopangira ma electrode owotcherera kumatha kukhala ngati chothandizira kusungunula ndikupangira ma slag, kupondereza kutulutsa pakuwotcherera, kuchepetsa kuphulika, kupititsa patsogolo kutulutsa kwa slag, kupanga seam yowotcherera kukhala yoyera komanso yokongola, ndikuwonjezera mphamvu zamakina.Wollastonite angaperekenso calcium oxide kwa flux wa ndodo kuwotcherera, pamene kubweretsa silicon dioxide kupeza mkulu wamchere slag, amene angathe kuchepetsa moto pores ndi zina zolakwika pa mfundo.Kuchuluka kowonjezera nthawi zambiri ndi 10-20%.
