Kodi calcium carbonate imagwiritsidwa ntchito bwanji mu utoto?

Calcium carbonate ndi ufa woyera wopanda poizoni, wopanda fungo, wosakwiyitsa komanso ndi imodzi mwazodzaza zosunthika kwambiri. Calcium carbonate ndi yopanda pakeral, sasungunuka m'madzi komanso kusungunuka mu asidi. Malinga ndi njira zosiyanasiyana zopangira calcium carbonate, calcium carbonate imatha kugawidwa mu heavy calcium carbonate ndi light carbon.

Calcium acid, colloidal calcium carbonate ndi crystalline calcium carbonate. Calcium carbonate ndi chinthu chofala padziko lapansi. Amapezeka m'miyala monga vermiculite, calcite, choko, miyala yamchere, marble, travertine, etc. Ndiwo gawo lalikulu la mafupa a nyama kapena zipolopolo. Calcium carbonate ndi chinthu chofunikira chomangira ndipo chimagwiritsidwa ntchito kwambiri m'makampani.

Kugwiritsa ntchito calcium carbonate mu utoto wa latex

1. Udindo wa heavy calcium

• Monga pigment ya thupi, imakhala ndi mphamvu yodzaza kuti ikhale yabwino, yunifolomu, ndi yoyera.
• Iwo ali ena youma kubisala mphamvu, ndi jiniralamagwiritsa ntchito zinthu zabwino kwambiri. Pamene tinthu kukula ndi pafupi tinthu kukula kwa titaniyamu woipa, chophimba zotsatira za titaniyamu woipa akhoza bwino.
• Ikhoza kupititsa patsogolo mphamvu, kukana madzi, kuuma ndi kupukuta kukana kwa filimu yojambula.
• patsogolo mtundu kusunga.
• Chepetsani mtengo, kugwiritsa ntchito ndi 10% ~ 50%. Zoipa: kachulukidwe kachulukidwe, kosavuta kugwa, kuchuluka kwa ntchito sikuyenera kukhala kwakukulu.

 2. Ntchito ya calcium yowala

• Monga pigment ya thupi, imakhala ndi zotsatira zodzaza, zabwino, ndipo zimawonjezera kuyera.
• Ali ndi mphamvu yobisala yowuma.
• Kachulukidwe kakang'ono, malo enieniwo ndi aakulu, ndipo ali ndi katundu wina woyimitsidwa, ndipo amagwira ntchito yotsutsa-kukhazikitsa.
• Chepetsani ndalama.
• Wonjezerani kumverera. Zoipa: zosavuta kuyaka, kuphulika, kukhuthala, kuchuluka kwa ntchito sikuyenera kukhala kwakukulu, sikungagwiritsidwe ntchito pojambula kunja kwa khoma.

Kugwiritsa ntchito calcium carbonate mu zokutira ufa

• (1) Itha kugwiritsidwa ntchito ngati chodzaza zinthu zopaka gloss.
• (2) Semi-gloss zokutira mankhwala akhoza jinirally kuwonjezeredwa mwachindunji ndi kashiamu carbonate popanda kuwonjezera matting wothandizira, kupulumutsa mtengo.
• (3) Ndi mtundu woyera wa inorganic pigment womwe ungagwiritsidwe ntchito limodzi ndi titaniyamu woipa kuti achepetse ndalama.
• (4) Poyerekeza ndi zodzaza zina, calcium carbonate ndiyoyenera kwambiri kuzinthu zachilengedwe zomwe zimafuna zitsulo zolemera zochepa, monga zoseweretsa za ana ndi zonyamula ana.
• (5) Itha kuwongolera kuchuluka kwa ufa ndi malo opopera utoto, makamaka mu ufa wosakanikirana.
•  (6) Ngati kukana kwanyengo kwakunja kumafunika, sikungagwiritsidwe ntchito ngati chodzaza.
•  (7) Chifukwa cha kuyamwa kwake kwamafuta ambiri, ndikosavuta kuyambitsa peel ya lalanje pamwamba pa filimu ya utoto. Panthawiyi, mafuta ochepa a hydrogenated castor akhoza kuwonjezeredwa kuzinthu zapansi.
•  (8) Imakhala ngati chigoba kuti ionjezere makulidwe a filimu ya utoto ndikuwongolera kukana komanso kulimba kwa zokutira.

Kugwiritsa ntchito calcium carbonate mu zokutira zamatabwa

• (1) Kudzaza zinthu zamitundu phunziroli kuchepetsa mtengo.
• (2) Wonjezerani mphamvu ya filimu ndi kuvala kukana.
• (3) Kashiamu wopepuka ali ndi mphamvu yokhuthala pang'ono, yosavuta kusintha, komanso anti-sedimentation yabwino.
• (4) Kashiamu wolemera amachepetsa katundu wa mchenga mu filimu ya utoto, ndipo n'zosavuta kugwa mu thanki, choncho m'pofunika kumvetsera kulimbikitsa katundu wotsutsana ndi kumira.
• (5) Sinthani gloss, kuuma ndi kuyera kwa filimu ya utoto.
• (6) Siziyenera kugwiritsidwa ntchito limodzi ndi inki yolimbana ndi alkali ndi zodzaza.

Kugwiritsa ntchito calcium carbonate mu utoto wamagalimoto

 Ultra-fine calcium carbonate yokhala ndi tinthu ting'onoting'ono tochepera 80nm imagwiritsidwa ntchito ngati zokutira zotsutsana ndi miyala ndi topcoat ya chassis yamagalimoto chifukwa cha thixotropy wake wabwino. Kuchuluka kwa msika ndi 7000 ~ 8000t/a, ndipo mtengo pamsika wapadziko lonse lapansi ndi wokwera mpaka 1100~1200 USD/t. .

Kugwiritsa ntchito calcium carbonate mu inki

Ultrafine calcium carbonate imagwiritsidwa ntchito mu inki, imawonetsa kufalikira kwabwino, kuwonekera, gloss yabwino kwambiri ndi kubisala mphamvu, komanso kutsatsa kwa inki ndi kuyanika, zomwe ziyenera kutsegulidwa kuti zipange makristalo ozungulira kapena a cuboid.
