Aluminum hydroxide, Nwa nke nke bụ Al (OH) 3, nwere ike dị na ọdịdị na-esonụ iche: gibbsite, nke bụ ịnweta, na doyleite, nordstrandite na bayerite, nile nke dị ụkọ polymorphs. Dabere na ya Njirimara, anyị nwere ike ikwu na aluminum hydroxide yiri ka ihe antacid. Ọ nwere dị iche iche na-eji eme ihe bụ isi otu nke bụ ọgwụ ngwa.
Chemical Properties
E nwere ọtụtụ dị iche iche nke aluminum oxide, gụnyere ma crystalline na-abụghị crystalline iche-iche. Ọ bụ ihe ọkụ insulator, nke pụtara na ọ na-adịghị na-eduzi ọkụ, na ihe ọ na-nwere dịtụ elu thermal conductivity. Ke adianade do, ya crystalline ụdị, corundum, ya ekweghị ekwe-eme ka ọ kwesịrị ekwesị dị ka ihe abrasive. The elu agbaze n'ókè nke aluminum oxide-eme ka ọ dị mma refractory ihe n'ihi na lining elu-okpomọkụ ngwa dị ka kilns, ite-ọku uku, incinerators, ngwa agha dị iche iche na ụdị, na crucibles.
Njirimara nke aluminum hydroxide
The ọcha aluminum hydroxide nwere ụdị keukwu powder nke na-acha ọcha na agba ma ọ bụ nsogbu dị iche iche na njupụta fọrọ nke nta 2,42 g kwa ml. Aluminum hydroxide agaghị igbari na mmiri, kama ọ ga igbari naanị na ndọkwasi nile na asịd. I nwere ike na-atụ anya aluminum hydroxide na-eme ihe dị ka ihe amphoteric umi mmiri. Ọ bụrụ na a siri ike isi bụ ugbu a, aluminum hydroxide ga-eme ihe dị ka ihe acid. Ma ọ bụrụ na a siri ike acid bụ ugbu a, ọ ga-eme ihe dị ka a siri ike isi.
Aluminum hydroxide ga-edozi na-elezi anya n'ihi ya ikpughe nwere ike ime ka iyatesịt. Otú ọ dị, naanị obere na mmapụta unan ga-adị ugbu a. Ma flammability, aluminum hydroxide abụghị flammable na ga ọkụ. E wezụga, aluminum hydroxide bụghị reactive, ya mere, ọ bụ anụ na ma ọkụ na mmiri na ọnọdụ.
Ngwa nke aluminum hydroxide
Aluminium hydroxide nwere ọtụtụ ngwa; ụfọdụ ndị kweere na ojiji ndị a bụ n'ezie ndị na-adịghị agwụ agwụ. Dị nnọọ iji gosi nghọta dị ukwuu nke ojiji, anyị nwere ike ikwu na aluminum hydroxide eji dị mordant na e ji esiji ákwà, purifier maka mmiri, mgwa maka ntecha, na ọbụna dị ka ihe mmewere maka Filiks na foto. E nwekwara ngwa nke obere agwa ceramik na-ewu. Ma ndị kasị mkpa n'ọhịa ebe aluminum hydroxide na-etinyere bụ na nkà mmụta ọgwụ.
Ngwa na nkà mmụta ọgwụ
Nyere na aluminum hydroxide bụ ike neutralize asịd, ọ na-eje ozi dị ka a eke antacid. Aluminum hydroxide nwekwara a nnọọ uru ihe onwunwe dị ka ọ na-akpali dịghịzi usoro mmadụ. E wezụga, dị iche iche vaccines, gụnyere ndị na-na-emeso ịba ọcha n'anya B, ịba ọcha n'anya A, na tetanus, na-kwadebere iji aluminum hydroxide. Ọ nwere ike na-eji maka ọgwụgwọ nke akụrụ ọrịa ndị nwere elu larịị nke phosphates ọbara n'ihi gbasara akụrụ odida. Nke a bara uru atụmatụ dị n'ihi na ike nke aluminum hydroxide eke agbụ na phosphates. Mgbe nkịtị na aluminum hydroxide, phosphates bụ flushed si ahụ mmadụ mfe.
Ntecha ngwa
E nwere dị iche iche ngwa maka aluminum hydroxide na ubi nke ntecha. Aluminum hydroxide na-ọtụtụ ugboro ugboro-eji maka mmepụta nke lipsticks, ka-acha ọkụ, na ndị ọzọ na ngwaahịa maka nlekọta anụ. Ọ na-eji n'ebe ahụ n'ihi na ọ bụ kpam kpam mụ na ndị na-abụghị na-egbu egbu ndị mmadụ. Mgbe ụfọdụ aluminum hydroxide emepụta ihe ntecha na-eji aluminum hydroxide na-emepụta-ekpocha maka anụ ahụ, suntan ngwaahịa, ahụ lotions, na moisturizers. Personal elekọta ngwaahịa, n'ihi na ihe atụ, shampoos, toothpastes, deodorants na ọtụtụ ndị ọzọ, na-na-agụnye iji nke aluminum hydroxide. Aluminum hydroxide na-mgbe ụfọdụ na-eji maka nchebe nke ụmụ mmadụ na anụ.
Ngwa na ụlọ ọrụ
Concrete ike-emepụta enweghị aluminum hydroxide. On ogbo nke mmepụta nke ihe aluminum hydroxide na-agbakwunyere ciment. Ọ bụkwa nnọọ uru n'ihi na simenti na aluminum hydroxide adianade dries ngwa ngwa ma ọ bụrụ na ọ na a na-gụrụ ikpo. Ceramics na iko ma ulo oru na n'ụlọ ngwa arụpụtara eji aluminum hydroxide. The kasị bara uru atụmatụ nke aluminum hydroxide mgbe ọ na-atụkwasịkwara iko mejupụtara na eziokwu na ọ na-eme ka iko okpomọkụ na-eguzogide. Ọ bụ omume n'ihi na, dị ka e ekwuola, aluminum hydroxide abụghị flammable na elu agbaze ebe. Aluminum hydroxide jikọtara na Polymers yiri ka a dị ezigbo mma ọkụ retardant.
