Yintoni ukufakwa kwecalcium carbonate kwiipeyinti?

I-Calcium carbonate ayiyotyhefu, ayinavumba, ayithukuthezi ngumgubo omhlophe kwaye yenye yezona zinto zisebenza ngeendlela ezininzi zokuzalisa i-inorganic fillers. I-calcium carbonate i-neutral, ayinyibiliki kakhulu emanzini kwaye inyibilika kwiasidi. Ngokweendlela ezahlukeneyo zokuvelisa i-calcium carbonate, i-calcium carbonate inokwahlulwa ibe yi-calcium carbonate enzima kunye nekhabhoni ekhanyayo.

I-calcium acid, i-colloidal calcium carbonate kunye ne-crystalline calcium carbonate. I-calcium carbonate yinto eqhelekileyo emhlabeni. Ifumaneka kumatye afana ne-vermiculite, i-calcite, i-chalk, i-limestone, i-marble, i-travertine, njl. I-calcium carbonate yinto ebalulekileyo yokwakha kwaye isetyenziswa kakhulu kwishishini.

Ukusetyenziswa kwe-calcium carbonate kwipeyinti ye-latex

1. Indima ye-calcium enzima

• Njengombala womzimba, unempembelelo yokuzalisa ukuyenza ibe ntle, iyunifomu, kwaye imhlophe.
• Inamandla athile okufihla owomileyo, kunye nofuzoralsebenzisa iimveliso ezilungileyo kakhulu. Xa i-particle size isondele kwi-particle size ye-titanium dioxide, umphumo wokugubungela we-titanium dioxide unokuphuculwa.
• Inokuphucula amandla, ukuchasana kwamanzi, ukoma kunye nokuxhatshazwa kwe-scrub yefilimu yokupenda.
• phucula umbala ukugcinwa.
• Ukunciphisa iindleko, ukusetyenziswa yi-10% ~ 50%. Ukungalungi: ubuninzi obuphezulu, kulula ukukhwela, ubungakanani bokusetyenziswa akufanele bube bukhulu kakhulu.

 2. Indima ye-calcium ekhanyayo

• Njengombala womzimba, unempembelelo yokuzalisa, ilungile, kwaye yandisa ubumhlophe.
• Unamandla athile okufihla owomileyo.
• Ukuxinana kuncinci, indawo ethile yendawo enkulu, kwaye inepropati ethile yokunqunyanyiswa, kwaye idlala indima yokuchasana nokuhlaliswa.
• Nciphisa iindleko.
• Yandisa ukuziva. Ukungalungi: kulula ukuvutha, ukuvutha, ukuqina, umthamo wokusetyenziswa akufanele ube mkhulu kakhulu, awukwazi ukusetyenziswa kwipeyinti yodonga lwangaphandle.

Ukusetyenziswa kwe-calcium carbonate kwi-powder coating

• (1) Ingasetyenziswa njengesizalisi kwiimveliso zokugquma kweglosi ephezulu.
• (2) Iimveliso zokugquma kwe-semi-gloss zinokufuzaralifakwe ngokuthe ngqo nge-calcium carbonate ngaphandle kokongezwa kwe-agent yokulinganisa, ukonga iindleko.
• (3) Yibala elimhlophe le-inorganic pigment enokusetyenziswa kunye ne-titanium dioxide ukunciphisa iindleko.
• (4) Xa kuthelekiswa namanye ama-fillers, i-calcium carbonate iyona nto ifanelekileyo kwiimveliso ezihambelana nokusingqongileyo ezifuna amanqanaba aphantsi esinyithi esinzima, njengamathoyizi abantwana kunye neenqwelo zeentsana.
• (5) Inokuphucula izinga lomgubo kunye nendawo yokutshiza yepeyinti, ngakumbi kumgubo oxutywe.
•  (6) Ukuba ukuchasana kwemozulu kwangaphandle kuyadingeka, akunakusetyenziswa njengento yokuzalisa.
•  (7) Ngenxa yokufunxa kwayo i-oyile eninzi, kulula ukwenza ixolo leorenji kumphezulu wefilimu yepeyinti. Ngeli xesha, ioli encinci ye-hydrogenated castor inokongezwa kwizinto ezisisiseko.
•  (8) Isebenza njenge-skeleton yokwandisa ubukhulu befilimu yepeyinti kunye nokuphucula ukuxhathisa ukunxiba kunye nokuqina kwengubo.

Ukusetyenziswa kwe-calcium carbonate kwiingubo zokhuni

• (1) Ukuzalisa izinto ezinemibala kuqala ukunciphisa iindleko.
• (2) Ukwandisa amandla efilimu kunye nokuxhatshazwa kokugqoka.
• (3) Ikhalsiyam ekhanyayo inempembelelo encinci yokutyeba, kulula ukuyitshintsha, kunye ne-anti-sedimentation elungileyo.
• (4) I-calcium enzima iyanciphisa ipropati ye-sanding kwifilimu yepeyinti, kwaye kulula ukukhawuleza kwi-tank, ngoko kuyimfuneko ukunyamekela ukuqinisa ipropati yokuchasana.
• (5) Ukuphucula iglosi, ukoma kunye nokumhlophe kwefilimu yepeyinti.
• (6) Akufunekanga isetyenziswe kunye ne-alkali-resistant pigments kunye ne-fillers.

Ukusetyenziswa kwe-calcium carbonate kwipeyinti yemoto

 I-Ultra-fine calcium carbonate enobungakanani besuntswana elingaphantsi kwe-80nm isetyenziselwa ukugquma ilitye kunye ne-topcoat ye-chassis yemoto ngenxa ye-thixotropy yayo elungileyo. Umthamo wemarike yi-7000 ~ 8000t / a, kwaye ixabiso kwimarike yamazwe ngamazwe liphezulu njenge-1100 ~ 1200 USD / t. .

Ukusetyenziswa kwe-calcium carbonate kwi-inki

I-Ultrafine calcium carbonate isetyenziswa kwii-inki, ibonisa ukuchithwa okugqwesileyo, ukungafihli, iglosi egqwesileyo kunye namandla okufihla, kunye neempawu ezigqwesileyo ze-inki zokubhengeza kunye nokomisa, ekufuneka zivulwe ukuze zenze iikristale ezingqukuva okanye ezi cuboid.
