Yankho

Barium sulfate ndi mankhwala ofunikira kwambiri osapangidwa kuchokera ku miyala ya barite. Sikuti imangokhala ndi mawonekedwe abwino komanso kukhazikika kwa mankhwala, komanso ili ndi makhalidwe apadera monga kuchuluka, kukula kwa quantum ndi mawonekedwe ake. Chifukwa chake, imagwiritsidwa ntchito kwambiri mu zokutira, mapulasitiki, mapepala, rabara, inki ndi pigment ndi zina. Nanometer barium sulfate ili ndi ubwino wokhala ndi malo apadera, ntchito yayikulu, kufalikira bwino, ndi zina zotero. Imatha kuwonetsa magwiridwe antchito abwino ikagwiritsidwa ntchito pazinthu zophatikizika. HCMilling (Guilin Hongcheng) ndi katswiri wopanga zinthubaritemphero yoperamakina athu.baritechozungulira choyimiriramphero Makina amatha kupukusa ufa wa barite wa 80-3000. Izi ndi zomwe zikuwonetsa momwe nano barium sulfate imagwiritsidwira ntchito.

1. Makampani opanga pulasitiki — pambuyo pokonza ndi baritemphero yoperamakina

Kuwonjezera nano barium sulfate yomwe imakonzedwa ndi makina opera a barite ku polima kuti ipeze zinthu zophatikizika zolimba komanso zolimba kwambiri kwakopa chidwi chachikulu. Mwachitsanzo, barium sulfate ikhoza kuwonjezeredwa ku polyethylene (PE), polypropylene (PP), polylactic acid (PLA), polytetrafluoroethylene (PTFE) ndi zinthu zina. Makamaka, mphamvu zamakina za barium sulfate zasintha kwambiri pambuyo pa kusintha kwa pamwamba.

Pazinthu zambiri zopangidwa ndi polima, pamene kuchuluka kwa chosinthira kumawonjezeka, mphamvu ndi kulimba kwa zinthu zopangidwa ndi polima kumawonjezeka kaye kenako kumachepa. Izi zili choncho chifukwa kuchuluka kwa chosinthira kumatsogolera ku kulowetsedwa kwa thupi kwa zigawo zambiri pamwamba pa nano barium sulfate, zomwe zimapangitsa kuti polima agwirizane kwambiri, zomwe zimakhudza mawonekedwe a makina a zinthu zopangidwa ndi polima, ndikupangitsa kuti zikhale zovuta kusewera makhalidwe abwino a zinthu zopangidwa ndi polima; Kuchuluka kochepa kwa chosinthira kumawonjezera zolakwika pakati pa nano barium sulfate ndi polima, zomwe zimapangitsa kuti mawonekedwe a makina a chophatikizacho achepe.

Kuwonjezera pa kuchuluka kwa pamwamba komwe kwatchulidwa pamwambapa kumakhudza kwambiri mawonekedwe a makina a composite, kuchuluka kwa barium sulfate nakonso ndikofunikira. Izi zili choncho chifukwa mphamvu ya nano barium sulfate ndi yayikulu kwambiri, yomwe ingathandize ponyamula ikawonjezedwa ku composite, motero imapanga mphamvu yolimbitsa. Komabe, pamene kuchuluka kwa nano barium sulfate kuli kokwera kwambiri (kuposa 4%), chifukwa cha kusonkhana kwake mu composite ndi kuwonjezera tinthu tosapanga organic, zolakwika za matrix zimawonjezeka, zomwe zimapangitsa kuti composite ikhale yosavuta kusweka, motero zimapangitsa kuti mawonekedwe a makina a composite akhale oyipa kwambiri. Chifukwa chake, kuchuluka kwa barium sulfate kuyenera kukhala mkati mwa mawonekedwe ake oyenera a makina.

2. Makampani opaka utoto — pambuyo pokonza ndibaritemphero yoperamakina

Monga mtundu wa utoto, barium sulfate imagwiritsidwa ntchito kwambiri popaka utoto ndipo imagwira ntchito yofunika kwambiri pakukweza makulidwe, kukana kukwawa, kukana madzi, kukana kutentha, kuuma pamwamba komanso kukana kukhudza kwa utoto. Kuphatikiza apo, chifukwa cha kuyamwa mafuta pang'ono komanso mphamvu yayikulu yodzaza, ingagwiritsidwe ntchito popaka utoto pogwiritsa ntchito madzi, ma primer, zopaka zapakati komanso zopaka utoto pogwiritsa ntchito mafuta kuti muchepetse mtengo wa utoto. Ikhoza kulowa m'malo mwa 10% ~ 25% ya titanium dioxide mu zopaka utoto pogwiritsa ntchito madzi. Zotsatira zake zikusonyeza kuti kuyera kwawonjezeka ndipo mphamvu yobisala siichepa.

Makhalidwe a barium sulfate yabwino kwambiri pazophimba ndi awa: 1) kukula kwa tinthu tating'onoting'ono komanso kufalikira kwa tinthu tating'onoting'ono; 2) Ndi yowonekera bwino ikafalikira mu resin solution; 3) Kufalikira bwino mu zinthu zoyambira zophimba; 4) Ingagwiritsidwe ntchito ngati chotulutsira pamodzi ndi utoto wachilengedwe; 5) Ikhoza kusintha mawonekedwe a thupi.

3. Makampani opanga mapepala — pambuyo pokonza ndi baritechozungulira choyimiriramphero makina

Barium sulfate nthawi zambiri imagwiritsidwa ntchito popanga mapepala chifukwa cha kukhazikika kwake kwabwino kwa thupi ndi mankhwala, kuuma pang'ono, kuyera kwakukulu, komanso kuyamwa kwa kuwala koopsa.

Mwachitsanzo, pepala la kaboni ndi lofala kwambiri pophunzira komanso ndi zinthu za muofesi, koma pamwamba pake ndi posavuta kusintha mtundu, kotero barium sulfate imafunika kuti ikhale ndi mafuta ambiri, zomwe zingathandize kuti inki ilowe m'pepala; Kukula kwa tinthu tating'onoting'ono ndi kochepa komanso kofanana, zomwe zingapangitse pepalalo kukhala lathyathyathya komanso kupangitsa kuti makina asawonongeke kwambiri.

4. Makampani opanga ulusi wa mankhwala — pambuyo pokonza ndi baritechozungulira choyimiriramphero makina

Ulusi wa Viscose, womwe umadziwikanso kuti "thonje lopangira", umafanana ndi ulusi wachilengedwe wa thonje, monga anti-static, chinyezi chabwino, utoto wosavuta, komanso kukonza nsalu mosavuta. Nano barium sulfate ili ndi zotsatira zabwino za nano. Ulusi wosakaniza wa nano barium sulfate/wosinthidwa wa cellulose wopangidwa kuchokera ku zinthu ziwirizi ndi mtundu watsopano wa ulusi wophatikizika, womwe ungasunge mawonekedwe apadera a gawo lililonse. Kuphatikiza apo, kudzera mu "mgwirizano" pakati pawo, ukhoza kulipira zofooka za chinthu chimodzi ndikuwonetsa mawonekedwe atsopano a zinthu zophatikizika.
