Ọ bụrụ na ntụ ntụ mica azụrụ enweghị mmetụta pearlescent dị mma ma ọ bụ na ọ nweghị mmetụta pearlescent, a kwesịrị ilebara anya n'oge a.

Isi ihe e ji eme ntụ ntụ mica na mkpuchi.

A na-egosipụtakarị ojiji nke ntụ ntụ mica n'ime ihe mkpuchi n'akụkụ ndị a:

1. Mmetụta mgbochi: Ihe ndị e ji mee ihe ndị dị ka mpempe akwụkwọ na-emepụta nhazi dị mfe nke dabara adaba n'ime ihe nkiri agba, a na-egbochikwa ntinye mmiri na ihe ndị ọzọ na-emebi emebi n'ime ihe nkiri agba ahụ nke ukwuu. Mgbe ejiri ntụ sericite dị elu (oke dayameta na ọkpụrụkpụ nke chip ahụ dịkarịa ala ugboro 50, ọkacha mma karịa ugboro 70), oge ịbanye mmiri na ihe ndị ọzọ na-emebi emebi site na ihe nkiri agba ahụ na-agbatịkarị ugboro atọ. N'ihi eziokwu ahụ bụ na ihe ndị na-eme ka ntụ ntụ sericite dị ọnụ ala karịa resin pụrụ iche, ha nwere uru teknụzụ na akụ na ụba dị elu. Ojiji nke ntụ sericite dị elu bụ ụzọ dị mkpa iji melite mma na arụmọrụ nke mkpuchi mgbochi corrosion na mkpuchi mgbidi mpụta. N'oge usoro mkpuchi ahụ, a na-etinye ibe sericite n'elu nrụgide tupu ihe nkiri agba ahụ agbaa ike, na-emepụta ihe owuwu nke dabara na ibe ya na elu nke ihe nkiri agba ahụ. Ndokwa oyi akwa a site na oyi akwa, yana ntụzi ya kpọmkwem na ntụziaka ebe ihe ndị na-emebi emebi na-abanye na ihe nkiri agba ahụ, nwere mmetụta mgbochi kachasị dị irè.
2. Imeziwanye ihe ndị dị na ihe nkiri agba: Ojiji nke ntụ sericite nwere ike imeziwanye usoro ihe ndị dị na ihe nkiri agba. Isi ihe dị na ya bụ njirimara ọdịdị nke ihe mkpuchi ahụ, ya bụ, nha nha dayameta na ọkpụrụkpụ nke ihe mkpuchi dị ka mpempe akwụkwọ na nha nha ogologo na dayameta nke ihe mkpuchi eriri. Ihe mkpuchi ahụ, dị ka ájá na nkume dị na simenti, na-arụ ọrụ na-eme ka ogwe ígwè sie ike.
3. Ime ka ihe mkpuchi agba ahụ ka mma: Ike nke resin n'onwe ya pere mpe, ike nke ọtụtụ ihe mkpuchi adịghịkwa elu (dịka ntụ ntụ talc). N'ụzọ megidere nke ahụ, sericite bụ otu n'ime ihe ndị mejupụtara granite, nwere ike siri ike na ike igwe. Ya mere, itinye ntụ ntụ sericite dị ka ihe mkpuchi na mkpuchi ahụ nwere ike ime ka iguzogide iyi ya ka mma nke ukwuu. Ọtụtụ ihe mkpuchi ụgbọ ala, ihe mkpuchi okporo ụzọ, ihe mkpuchi igwe na-egbochi ire ere, na ihe mkpuchi mgbidi na-eji ntụ ntụ sericite.
4. Arụmọrụ mkpuchi: Sericite nwere oke iguzogide ma bụrụkwa ihe mkpuchi kachasị mma. Ọ na-emepụta ihe mgbagwoju anya na resin silicon organic ma ọ bụ resin silicon boron organic ma na-agbanwe ya ka ọ bụrụ ihe seramiiki nwere ezigbo ike mekaniki na arụmọrụ mkpuchi mgbe ọ na-ezute oke okpomọkụ. Ya mere, waya na eriri e ji ụdị ihe mkpuchi a mee ka ha na-anọgide na-enwe ọnọdụ mkpuchi mbụ ha ọbụlagodi mgbe ọkụ gbasịrị ha. Ọ dị oke mkpa maka ogbunigwe, ọwara, ụlọ pụrụ iche, ụlọ pụrụ iche, wdg.
5. Ihe na-egbochi ire ọkụ: Ntụ Sericite bụ ihe na-eme ka ire ọkụ dị mma. Ọ bụrụ na ejikọtara ya na ihe na-egbochi ọkụ halogen organic, enwere ike ịkwadebe ihe na-egbochi ire ọkụ na ihe mkpuchi na-anaghị agba ọkụ.
6. Nguzogide UV na infrared: Sericite nwere arụmọrụ dị mma n'ichebe megide ultraviolet na infrared radieshon. Ya mere, itinye ntụ sericite mmiri mmiri na mkpuchi mpụta nwere ike ime ka iguzogide UV nke ihe nkiri agba dịkwuo mma ma mee ka ọ ghara ịka nká. A na-eji arụmọrụ nchekwa infrared ya akwadebe ihe mkpuchi na ihe mkpuchi (dịka mkpuchi).
7. Radiation okpomọkụ na mkpuchi okpomọkụ dị elu: Sericite nwere ezigbo ike radiation infrared, dịka ya na iron oxide, nke nwere ike ịmepụta mmetụta radiation okpomọkụ dị mma.
8. Mmetụta nke mkpuchi ụda na mmetụta nke ịmịkọrọ ujo: Sericite nwere ike ịgbanwe usoro modulu anụ ahụ nke ihe, na-akpụ ma ọ bụ na-agbanwe viscoelasticity ha. Ụdị ihe a na-amịkọrọ ike ịma jijiji nke ọma, na-ebelata ebili mmiri na ebili mmiri ụda. Na mgbakwunye, ntụgharị ugboro ugboro nke ebili mmiri na ebili mmiri ụda n'etiti mica chips na-ebelatakwa ike ha. A na-ejikwa ntụ ntụ Sericite kwadebe mkpuchi mkpuchi ụda, ihe mgbochi ụda, na ihe mgbochi ujo.
